This file is offered as-is, +without warranty of any kind. + +Basic Installation +================== + + Briefly, the shell command `./configure && make && make install' +should configure, build, and install this package. The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. Some packages provide this +`INSTALL' file but do not implement all of the features documented +below. The lack of an optional feature in a given package is not +necessarily a bug. More recommendations for GNU packages can be found +in *note Makefile Conventions: (standards)Makefile Conventions. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + + The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package, generally using the just-built uninstalled binaries. + + 4. Type `make install' to install the programs and any data files and + documentation. When installing into a prefix owned by root, it is + recommended that the package be configured and built as a regular + user, and only the `make install' phase executed with root + privileges. + + 5. Optionally, type `make installcheck' to repeat any self-tests, but + this time using the binaries in their final installed location. + This target does not install anything. Running this target as a + regular user, particularly if the prior `make install' required + root privileges, verifies that the installation completed + correctly. + + 6. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 7. Often, you can also type `make uninstall' to remove the installed + files again. In practice, not all packages have tested that + uninstallation works correctly, even though it is required by the + GNU Coding Standards. + + 8. Some packages, particularly those that use Automake, provide `make + distcheck', which can by used by developers to test that all other + targets like `make install' and `make uninstall' work correctly. + This target is generally not run by end users. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. This +is known as a "VPATH" build. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple `-arch' options to the +compiler but only a single `-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the `lipo' tool if you have problems. + +Installation Names +================== + + By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX', where PREFIX must be an +absolute file name. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. In general, the +default for these options is expressed in terms of `${prefix}', so that +specifying just `--prefix' will affect all of the other directory +specifications that were not explicitly provided. + + The most portable way to affect installation locations is to pass the +correct locations to `configure'; however, many packages provide one or +both of the following shortcuts of passing variable assignments to the +`make install' command line to change installation locations without +having to reconfigure or recompile. + + The first method involves providing an override variable for each +affected directory. For example, `make install +prefix=/alternate/directory' will choose an alternate location for all +directory configuration variables that were expressed in terms of +`${prefix}'. Any directories that were specified during `configure', +but not in terms of `${prefix}', must each be overridden at install +time for the entire installation to be relocated. The approach of +makefile variable overrides for each directory variable is required by +the GNU Coding Standards, and ideally causes no recompilation. +However, some platforms have known limitations with the semantics of +shared libraries that end up requiring recompilation when using this +method, particularly noticeable in packages that use GNU Libtool. + + The second method involves providing the `DESTDIR' variable. For +example, `make install DESTDIR=/alternate/directory' will prepend +`/alternate/directory' before all installation names. The approach of +`DESTDIR' overrides is not required by the GNU Coding Standards, and +does not work on platforms that have drive letters. On the other hand, +it does better at avoiding recompilation issues, and works well even +when some directory options were not specified in terms of `${prefix}' +at `configure' time. + +Optional Features +================= + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + + Some packages offer the ability to configure how verbose the +execution of `make' will be. For these packages, running `./configure +--enable-silent-rules' sets the default to minimal output, which can be +overridden with `make V=1'; while running `./configure +--disable-silent-rules' sets the default to verbose, which can be +overridden with `make V=0'. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU +CC is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + HP-UX `make' updates targets which have the same time stamps as +their prerequisites, which makes it generally unusable when shipped +generated files such as `configure' are involved. Use GNU `make' +instead. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its `' header file. The option `-nodtk' can be used as +a workaround. If GNU CC is not installed, it is therefore recommended +to try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + + On Solaris, don't put `/usr/ucb' early in your `PATH'. This +directory contains several dysfunctional programs; working variants of +these programs are available in `/usr/bin'. So, if you need `/usr/ucb' +in your `PATH', put it _after_ `/usr/bin'. + + On Haiku, software installed for all users goes in `/boot/common', +not `/usr/local'. It is recommended to use the following options: + + ./configure --prefix=/boot/common + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS + KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf limitation. Until the limitation is lifted, you can use +this workaround: + + CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of all of the options to `configure', and exit. + +`--help=short' +`--help=recursive' + Print a summary of the options unique to this package's + `configure', and exit. The `short' variant lists options used + only in the top level, while the `recursive' variant lists options + also present in any nested packages. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made.

It was renamed + to `posix.spawn` shortly after introduction, and can still be accessed + by the new symbol name. + +### Bugs Fixed + + - `local posix = require "posix"` works again, fixing the regression + introduced in the last release. The automated Travis checks have been + improved to catch this sort of bug in future. + + +## Noteworthy changes in release 33.3.0 (2015-02-28) [stable] + +### New Features + + - Improved documentation of `sockaddr` tables for `posix.sys.socket` calls. + + - New `posix.sys.socket.getsockname` binding. + + - Remove the `posix.bit32` library, and use Lua’s built-in `bit32` library. + + - Can now be linked against NetBSD curses, albeit with several functions + not implemented by that library returning a "not implemented" error as + a consequence. + + - New functions `popen`, `popen_pipeline` and `pclose` mimic the POSIX + functions of the same name while allowing tasks to be Lua functions. + + - `fdopen` has been re-added, working on all supported Lua versions. + + - `execx` allows a Lua function or command to be exec’d; `spawn` is now + implemented in terms of it. + +### Incompatible Changes + + - The ncurses-only `KEY_MOUSE` definition has been removed from + `posix.curses`. + +### Bugs Fixed + + - `posix.sys.resource` only provides RLIM_SAVED_CUR and RLIM_SAVED_MAX if + they are defined by the C library (which FreeBSD 10 does not). + + - `posix.dirent.dir` and `posix.dirent.files` now raise a Lua `error()` + when unable to open the path argument, for orthogonality with `io.lines`. + + - Workaround for manifest key clash between `posix.so` and `posix.lua` in + LuaRocks. + + +## Noteworthy changes in release 33.2.1 (2015-01-04) [stable] + +### Bugs Fixed + + - Install posix.curses.html documentation file correctly. + + +## Noteworthy changes in release 33.2.0 (2015-01-03) [stable] + +### New Features + + - QNX support. + +### Bugs Fixed + + - `posix.time.gmtime` and `posix.time.localtime` specifications now + work correctly in January too! + + +## Noteworthy changes in release 33.1.0 (2014-12-19) [stable] + +### New Features + + - New `posix.bit32` module with band, bnot and bor functions that can be + used from any supported Lua release, without worrying about loading an + external bit operations library. + + - Preliminary Lua 5.3.0 compatibility. + +### Bugs Fixed + + - No more 'Bad Hints' errors from `posix.sys.socket.getaddrinfo` on many + hosts. + + - `stdlib.setenv` accepts a 3rd argument again. + + +## Noteworthy changes in release 33.0.0 (2014-11-04) [stable] + +### New Features + + - The curses library is fully integrated into luaposix, including reasonably + comprehensive LDoc documentation (certainly much better than the single + wooly web-page in previous releases). For backwards compatibility, all + APIs are re-exported from the `curses` module. + + - Most constants available through luaposix are now listed in the LDocs of + the submodule that defines them. + + - For backwards compatibility, everything is still lumped together in the + `posix.???` namespace, but, now raw APIs have been reorganised according to + the POSIX header files they belong to: + + ```lua + local posix = require "posix" + local fcntl = require "posix.fcntl" + local unistd = require "posix.unistd" + + local fd = fcntl.open ("x", + bit32.bor (posix.O_WRONLY, posix.O_CREAT), "u=rw") + unistd.write (fd, "Hello, World!\n") + unistd.close (fd) + ``` + + This makes the documentation easier to navigate, and for a better mapping + between luaposix APIs and the C functions they wrap, so translating from + C is now easier than ever. + + - Each of the newly separated submodules is self-contained, and can be copied + to another project for compiling and/or loading in a custom Lua runtime. If + you want to make use of this, in addition to the source for the modules you + copy, you'll also need at least the files `ext/posix/_helpers.c` and + `ext/include/lua52compat.c`, and also `ext/include/strlcat.c` for one or + two of them. + + - Where submodule calls return a table representation of a similar C struct + from a POSIX API, the Lua return tables have an appropriate `_type` field + metatable entry compatible with lua-stdlib `std.object.type`. + + - `posix.signal.signal` now accepts the constants `posix.signal.SIG_DFL` or + `posix.signal.SIG_IGN` in place of the strings "SIG_DFL" and "SIG_IGN". + + - The submodule bindings `posix.time.gmtime`, `posix.time.localtime`, + `posix.time.mktime`, `posix.time.strftime` and `posix.time.strptime` now + accept or create PosixTm tables with 1-to-1 field name mappings with the + POSIX `struct tm`. The old APIs with custom field names is still available + as `posix.gmtime`, `posix.localtime`, `posix.mktime`, `posix.strftime` and + `posix.strptime`. + + - Similarly, `posix.time.nanosleep` now takes and returns a PosixTimespec + table. The old API is still available as `posix.nanosleep`. + + - Where supported by the underlying system, `posix.time.clock_getres` and + `posix.time.clock_gettime` now require a constant inte argument (newly + defined in the `posix.time` submodule), and returns a PosixTimespec table. + The old APIs are still available as `posix.clock_getres` and + `posix.clock_gettime`. + + - Add `posix.unistd.gethostid`. The old `posix.hostid` API is still available + as an alias. + + - Add group APIs from grp.h: `posix.grp.endgrent`, `posix.grp.getgrent`, + `posix.grp.getgrgid`, `posix.grp.getgrnam` and `posix.grp.setgrent`. + Consequently, `posix.getgroup` is now reimplemented in Lua over the POSIX + APIs. + + - `posix.getgroup` defaults to current effective group when called with no + arguments, for consistency with `posix.getpasswd` API. + + - Add pwd APIs from pwd.h: `posix.pwd.endpwent`, `posix.grp.getpwent`, + `posix.pwd.getpwnam`, `posix.pwd.getpwuid` and `posix.pwd.setpwent`. + Consequently, `posix.getpasswd` is now reimplemented in Lua over the POSIX + APIs. + + - Add missing constants from sys/resource.h: + `posix.sys.resource.RLIM_INFINITY`, `posix.sys.resource.RLIM_SAVED_CUR`, + `posix.sys.resource.RLIM_SAVED_MAX`, `posix.sys.resource.RLIMIT_CORE`, + `posix.sys.resource.RLIMIT_CPU`, `posix.sys.resource.RLIMIT_DATA`, + `posix.sys.resource.RLIMIT_FSIZE`, `posix.sys.resource.RLIMIT_NOFILE`, + `posix.sys.resource.RLIMIT_STACK`, `posix.sys.resource.RLIMIT_AS`. + + - Add missing APIs from unistd.h: `posix.unistd.getegid`, + `posix.unistd.geteuid`, `posix.unistd.getgid`, `posix.unistd.getuid`, + `posix.unistd.getpgrp`, `posix.unistd.getpid`, `posix.unistd.getppid`. + Consequently, `posix.getpid` is now reimplemented in Lua over the POSIX + APIs. + + - Add missing constants from signal.h; `posix.signal.SIG_DFL` and + `posix.signal.SIG_IGN'. + + - Add missing APIs from sys/stat.h: `posix.sys.stat.S_ISBLK`, + `posix.sys.stat.S_ISCHR`, `posix.sys.stat.S_ISDIR`, + `posix.sys.stat.S_ISFIFO`, `posix.sys.stat.S_ISLNK`, + `posix.sys.stat.S_ISREG`, `posix.sys.stat.S_ISSOCK`. + + - Add missing constants from sys/stat.h: `posix.sys.stat.S_IFMT`, + `posix.sys.stat.S_IFBLK`, `posix.sys.stat.S_IFCHR`, + `posix.sys.stat.S_IFDIR`, `posix.sys.stat.S_IFIFO`, + `posix.sys.stat.S_IFLNK`, `posix.sys.stat.S_IFREG`, + `posix.sys.stat.S_IRWXU`, `posix.sys.stat.S_IRUSR`, + `posix.sys.stat.S_IWUSR`, `posix.sys.stat.S_IXUSR`, + `posix.sys.stat.S_IRWXG`, `posix.sys.stat.S_IRGRP`, + `posix.sys.stat.S_IWGRP`, `posix.sys.stat.S_IXGRP`, + `posix.sys.stat.S_IRWXO`, `posix.sys.stat.S_IROTH`, + `posix.sys.stat.S_IWOTH`, `posix.sys.stat.S_IXOTH`, + `posix.sys.stat.S_ISGID`, `posix.sys.stat.S_ISUID`. + + - Add missing constants from syslog.h: `posix.syslog.LOG_CONS`, + `posix.syslog.LOG_NDELAY` and `posix.syslog.LOG_PID`. + + - Add missing API from syslog.h: `posix.syslog.LOG_MASK`. Use this to + convert syslog priority constants into mask bits suitable for bitwise + ORing as the argument to `posix.syslog.setlogmask`. + + - Add missing constants from time.h: `posix.time.CLOCK_MONOTONIC`, + `posix.time.CLOCK_PROCESS_CPUTIME_ID`, `posix.time.CLOCK_REALTIME` and + `posix.time.CLOCK_THREAD_CPUTIME_ID`. + + - New `posix.unistd.exec` and `posix.unistd.execp` require a table of + arguments, with [0] defaulting to the command name. The old string + tuple passing API is still available as `posix.exec` and `posix.execp`. + + - `posix.util.openpty` has moved to `posix.openpty`. The old API is still + available as an alias. + + - All posix APIs now fully and correctly diagnose extraneous and wrong + type arguments with an error. + + - Add `posix.IPC_NOWAIT`, `posix.MSG_EXCEPT` and `posix.MSG_NOERROR` + constants for message queues. + + - Add `posix.IPPROTO_UDP` for socket programming. + + - Add `posix.AI_NUMERICSERV` for posix.getaddrinfo hints flags. + + - Add `posix.WUNTRACED` for posix.wait flags. + + - Add `curses.A_COLOR` (where supported by the underlying curses library) for + extracting color pair assignments from the results of `curses.window.winch`. + + - Add missing `curses.KEY_F31` constant. + +### Bugs Fixed + + - `posix.fadvise` is now spelled `posix.fcntl.posix_fadvise` and takes a + file descriptor first argument rather than a Lua file handle. The old + misspelled bad argument type version is undocumented but still works. + + - `posix.getpasswd`, `posix.getpid`, `posix.pathconf`, `posix.stat`, + `posix.statvfs`, `posix.sysconf` and `posix.times` process a single table + argument with a list of types correctly. + + - `posix.syslog.openlog` now takes the bitwise OR of those constants. The + old string option specified API is still available as `posix.openlog`. + + - `posix.syslog.setlogmask` now takes the bitwise OR of bits returned by + passing priority constants to `posix.syslog.LOG_MASK`. The old API will + continue to be available as `posix.setlogmask`. + + - `posix.readlink` is much more robust, and reports errors accurately. + + - configured installation installs `posix.so` into the lua cpath directory + correctly. + + - fixed a long-standing bug where the stdio buffers were not restored after + some posix.fcntl() examples, resulting in the `make check` output being + truncated -- often before terminal colors were returned to normal. + + +## Noteworthy changes in release 32 (2014-05-30) [stable] + +### New Features + + - Support for posix.socketpair call and posix.AF_UNIX constant. + + - Previously undocumented spawn, pipeline, pipeline_iterator, pipeline_slurp, + euidaccess, timeradd, timercmp and timersub have been moved from the posix + table, which is reserved for strictly POSIX APIs to the posix.sys subtable. + The sys submodule automatically loads on first reference, so no need to + require it manually if you already have the main posix module loaded. + + - posix api documentation is separated into groups for better discovery. + +### Bugs Fixed + + - Builds correctly on hosts with no IPV6 capability. + + - Small improvements in organisation of generated html docs. + + - posix.openpty doesn't crash. + + - configure now detects Lua correctly with busybox grep. + + - Many fine portability fixes from latest gnulib. + + - Missing docs for accept, bind, connect, getaddrinfo, listen, recv, + recvfrom, send, sendto, setsockopt, shutdown, socket and socketpair apis + is now provided. + + - Missng docs for tcdrain, tcflow, tcflush, tcgetattr, tcsendbreak and + tcsetattr terminal apis are now provided. + + - Docs for apis implemented in Lua are now shown correctly. + + +## Noteworthy changes in release 31 (2013-09-09) [stable] + +### New Features + + - Missing termios cc flags are now available. + +### Bugs Fixed + + - posix.tcgetattr and posix.tcsetattr no save and restore all flags, + regardless of whether they are local extensions to POSIX. + + +## Noteworthy changes in release 30 (2013-08-29) [stable] + +### New Features + + - Support for file locks with fcntl() using F_SETLK, F_SETLKW, F_GETLK, + F_RDLCK, F_WRLCK and F_UNLCK. + + - Preliminary support for GNU Hurd, and OpenBSD. + +### Bugs Fixed + + - posix.shutdown can actually be called now. + + - Report the correct argument number in posix function error messages. + + - Much reduced compiler warning noise. + + - Many small typos and inconsistencies, see ChangeLog for details. + + +## Noteworthy changes in release 29 (2013-06-28) [stable] + + - This release adds wresize to curses, and sync, fsync, fdatasync, nice, + lseek as well as socket programming functions. Several small improvements + to the documentation were also added. + + - luaposix is compatible with Lua 5.1, Lua 5.2 and luajit 2.0, so the + 5.1 prefix to the release version has become an anachronism and has + been dropped from this release onwards. + +### New Features + + - Move to the Slingshot release system, which (among many other improvements) + fixes release tarballs from github to work with the standard GNU-style: + `./configure, make, make install`. `bootstrap` is still distributed for + those who need to re-bootstrap with a different version of gnulib and/or + slingshot. + + - Much improved former lunit and ad-hoc test scripts to Specl. + + +## Noteworthy changes in release 5.1.28 (2013-03-23) [stable] + + - This release fixes the previously unannounced posix.pipeline_iterator and + posix.pipeline_slurp functions, and adds a test for them. A workaround for + having LUA_INIT_5_2 set has been added to the build system. + + +## Noteworthy changes in release 5.1.27 (2013-03-17) [stable] + + - This release fixes broken Lua 5.1 compatibility in release 5.1.26 + (sorry! And thanks to Nick McVeity for the bug report and patch); renames + posix.system to posix.spawn (the old name is available for backwards + compatibility), generalizing it to take a shell command, file and + arguments, or Lua function; and adds posix.pipeline, which makes it easy + to run a pipeline of processes, each a shell command, program, or Lua + function. + + +## Noteworthy changes in release 5.1.26 (2013-03-04) [stable] + + - This release adds killpg, realpath and openpty, adds a flags parameter to + signal, and improves some documentation. + + +## Noteworthy changes in release 5.1.25 (2013-02-20) [stable] + + - This release adds support for message queues and UNIX 98 pseudoterminals + (thanks very much to the respective contributors), and allows argv[0] to + be set in exec calls. + + +## Noteworthy changes in release 5.1.24 (2013-02-15) [stable] + + - This release adds isatty and constants STDIN_FILENO, STDOUT_FILENO and + STDERR_FILENO, fixes a bug in readlink, adds a day field to time tables + for compatibility with os.date, and overhauls the build and release system. + + +## Noteworthy changes in release 5.1.23 (2012-10-04) [stable] + + - This release fixes the curses module for Lua 5.2; previously it would not + load with an unknown symbol error. The build process for luarocks has been + made more robust. + + +## Noteworthy changes in release 5.1.22 (2012-09-13) [stable] + + - This release fixes building on Mac OS X and some other OSes which don't + like building empty libraries. Thanks to Robert McLay for the bug report. + + +## Noteworthy changes in release 5.1.21 (2012-09-10) [stable] + + - This release adds comprehensive documentation for the posix module, from + Steve Donovan and Natanael Copa. + + - It makes one small change: rpoll now uses file descriptors, not Lua file + objects (hence, via fileno, it can use both). + + - Perhaps most importantly, it marks a change of maintainer, from + Reuben Thomas to Alexander Nikolaev. Thanks very much to Alexander for + agreeing to take over. Luaposix has garnered considerable interest in + recent months, and more contributors have stepped forwards with patches. + Alexander will help to oversee a maturing API, coordinate ongoing + improvements and additions, and help ensure that luaposix doesn't fall + back into disrepair as it has several times in the past. + + +## Noteworthy changes in release 5.1.20 (2012-06-22) [stable] + +### New Features + + - Improves signal handling. + - Improves the posix.system and creat functions (all thanks to Steve Donovan). + - Adds mkdtemp (thanks, 7hemroc). + - Adds statvfs (thanks to Like Ma). + - improves the tests. + - Adds some code guidelines. + +### Bugs Fixed + + - Fixes a bug in getgroup. + - Fixes some space leaks (thanks, Alexander Nikolaev), + - Copes with sysconf for _PC_PATH_MAX returning -1. + +### Incompatible Changes + + - The API of posix.open has changed to be more like the C version: the file + creation and status flags are now constants in the POSIX namespace. This + enables them to be used outside calls to open, and makes posix.open less + magic. posix.open will now raise an error if no creation flags are given + when O_CREAT is used. + + +## Noteworthy changes in release 5.1.19 (2012-04-10) [stable] + + - This release avoids the use of PATH_MAX, and copes with arbitrarily-long + paths. The implementation of strlcpy is changed to a BSD-licensed + implementation; the previously-used implementation was LGPL-licensed, which + is not MIT-compatible; thanks to Alexander Gladysh for bringing this + problem to my attention. (This was just mis-released as 5.1.18; sorry!) + + +## Noteworthy changes in release 5.1.18 (2012-03-26) [stable] + + - This release implements full Lua 5.2 compatibility; thanks to Enrico Tassi + for poking me to get this done. + + +## Noteworthy changes in release 5.1.17 (2012-02-29) [stable] + + - This release improves support for Lua 5.2; the curses module should now + work fine (the posix module still needs updating). Signal handling has been + improved to make it possible to chain to a C signal handler, and a bug in + resetting the process's signal mask after running a Lua handler has been + fixed. + + +## Noteworthy changes in release 5.1.16 (2012-02-18) [stable] + + - This release includes rewritten fcntl and signals support, and bug fixes + for read, chmod, getgroups and waitpid. curses boolean return values are + now Lua booleans rather than 0 for OK or ERR for not OK. fnmatch, strptime + and mktime are now supported, chmod now supports octal modes, thereâs + much expanded poll support, and some non-POSIX and obsolete features have + been removed. There are more tests and the build system has been improved. + Thanks go to the many contributors to this release. + + +## Noteworthy changes in release 5.1.15 (2011-09-29) [stable] + + - This release adds dup, pipe, pipe2 and more fcntl support (thanks to + Alexander V. Nikolaev and Alexander Gladysh for the patches). Two bugs in + the test code which used incorrect paths and caused only one set of tests + to run have been fixed. + + +## Noteworthy changes in release 5.1.14 (2011-09-19) [stable] + + - This release allows some constants to be case-insensitive in Lua, and fixes + a small build-system bug. + + +## Noteworthy changes in release 5.1.13 (2011-09-17) [stable] + +This release adds a rockspec. + + +## Noteworthy changes in release 5.1.12 (2011-09-09) [stable] + + - This release adds some basic functions such as open, close, read and write, + and integrates the pure Lua module which was previously in Lua stdlib. It + also adds a whole new module, curses, which was previously in the separate + lcurses project (curses is part of the POSIX standard). + +### Incompatible Changes + + - Note that the C part of the POSIX module is now called posix_c.so (or + similar), so if you have an old posix.so (or similar) you should delete it + to avoid clashing with the new posix.lua. + + +## Noteworthy changes in release 5.1.11 (2011-04-27) [stable] + + - Apologies, 5.1.10, released earlier today, had a buffer overflow bug + in the new mkstemp function. 5.1.11, just out, fixes it. + + +## Noteworthy changes in release 5.1.10 (2011-04-27) [stable] + +### This release adds mkstemp, adds some fixes for building on Mac OS X + (thanks to Gary Vaughan), removes some non-POSIX rlimit constants, + guards some functions that were not correctly guarded, so that they + will not be compiled on systems that don't support them, and makes + other minor fixes. + + +## Noteworthy changes in release 5.1.9 (2011-03-24) [stable] + +### New Features + + - support for signals and for getopt. See below for details. + + - Equally, there is still only the barest documentation: to use the various + APIs you have to grep to see if the one you want is there and then read the + C comment which gives the Lua API. If anyone is interested in adding better + documentation, I'd be delighted to hear from them. (My work on luaposix is + purely aimed at getting the support I need for GNU Zile, but as usual I + welcome patches from others. luaposix is still far from complete, so please + send patches for your favourite POSIX APIs!) + + - luaposix 5.1.9 improves compatibility with Darwin/Mac OS X, and adds + various new API bindings, for signals, getgroups, setting errno and + _exit, as well as some slight code cleanup. + + +## Noteworthy changes in release 5.1.8 (2013-03-23) [stable] + +### Bugs Fixed + + - fix bugs for setrlimit and gettimeofday. + - an improvement to test.lua. + - better use of POSIX feature macros to determine what APIs to support. + - removal of the obsolete timezone argument to gettimeofday, + - remove the non-POSIX gecos field of struct passwd + - improvements to the build system + - some code tidy-up, + - removal of Lua 5.0 compatibility + +### New APIs + + - abort, raise, isprint, isgraph, errno and stdio.h constants, and getopt_long. + + +## Noteworthy changes in release 5.1.7 (2013-03-23) [stable] + +A new minor bugfix release of luaposix is out. + +### Bugs Fixed + + - make clock_* functions' argument optional + - fixes posix.version string + + +## Noteworthy changes in release 5.1.6 (2010-08-11) [stable] + + - This release adds time functions: gettimeofday, clock_getres, + clock_gettime, localtime, gmtime, time, strftime. + + +## Noteworthy changes in release 5.1.5 (20??-??-??) [stable] + +The release notes for this release were lost in the mists of thyme. + + +## Noteworthy changes in release 5.1.4 (2008-07-18) [stable] + + - Includes a fix for rpoll() from debian[1] and a patch from openwrt[2] + that adds crypt(). + + +## Noteworthy changes in release 5.1.3 (2013-03-23) [stable] + +No changes. + + +## Noteworthy changes in release 5.1.2 (2008-01-29) [stable] + +### Incompatible changes + + - Please note that this release breakes the API for dup() and exec() + +### New Features + + - dup() now takes and returns lua files rather than file descriptors + (int). + + - exec() uses now execv(3) rather than execvp(3). This means that the + PATH environment variable is no longer used which means that all scripts + currently using exec() without an absolute path will break. If you need + the PATH variable, use the new execp() function. + + - Added openlog(), syslog() and closelog() functions. + + - The openlog(ident, [option], [facility]) function differs from the + recently released luasyslog by giving the user possibility to set + "option". The "option" parameter is a string containing one or more of + the chars: + + ``` + 'c' - LOG_CONS + 'n' - LOG_NDELAY + 'e' - LOG_PERROR + 'p' - LOG_PID + ``` + + It is possible to disable those funcs compile time by setting the + ENABLE_SYSLOG define to 0. + + - fileno() function was added. + + +## Noteworthy changes in release 5.1.1 (2008-01-25) [stable] + + - I have forked lposix. First release includes some patches submitted on + this list. + + This first release is basicly lposix with a cleaned up Makefile + the + patches found here: + + http://lua-users.org/lists/lua-l/2006-10/msg00448.html + http://lua-users.org/lists/lua-l/2007-11/msg00346.html + + - When the promised extened OS library[1] arrives I will most likely + remove the overlapping functions in luaposix. posix specific functions + that does not overlap will still be maintained and added. (e.g dup()) + + - Releases numbered 5.1.x[.y] will work with lua-5.1 series. The 'x' will + add/change features and .y releases will be strict bugfixes (no new + features). + + - I had planned to add syslog functions and fix dup() to handle lua files + (FILE*) rather than file descriptors (int). Now that luasyslog just + released I will have to re-evaluate that. diff --git a/README b/README new file mode 100644 index 0000000..6da3fb2 --- /dev/null +++ b/README @@ -0,0 +1,96 @@ +luaposix +======== + +By the [luaposix project][GitHub] + +[![travis-ci status](https://secure.travis-ci.org/luaposix/luaposix.png?branche=master)](http://travis-ci.org/luaposix/luaposix/builds) +[![Stories in Ready](https://badge.waffle.io/luaposix/luaposix.png?label=ready&title=Ready)](https://waffle.io/luaposix/luaposix) + +luaposix is a POSIX binding, including curses, for [Lua] 5.1, 5.2 and +5.3; like most libraries it simply binds to C APIs on the underlying +system, so it won't work on non-POSIX systems.

No non-POSIX APIs; no platform-specific code. When wrapping APIs + introduced in POSIX 2001 or later, add an appropriate #if.

Class posix.curses.chstr

+

Curses attributed string buffers.

+

An array of characters, plus associated curses attributes and +colors at each position.

+ +

Although marginally useful alone, the constants used to set colors +and attributes in chstr buffers are not defined until after +curses.initscr () has been called.

+ + +

Methods

+ + + + + + + + + + + + + + + + + + + + + +
posix.curses.chstr:dup ()Duplicate chstr.
posix.curses.chstr:get (o)Get information from the chstr.
posix.curses.chstr:len (cs)Retrieve chstr length.
posix.curses.chstr:set_ch (o, int[, attr=A_NORMAL[, rep=1]])Set a character in the buffer.
posix.curses.chstr:set_str (o, s[, attr=A_NORMAL[, rep=1]])Change the contents of the chstr.

Module posix.curses

+

Full-screen Text Terminal Manipulation.

+

In the underlying curses C library, the following functions:

+ + +
+getstr()   (and wgetstr(), mvgetstr(), and mvwgetstr())
+inchstr()  (and winchstr(), mvinchstr(), and mvwinchstr())
+instr()    (and winstr(), mvinstr(), and mvwinstr())
+
+ +

are subject to buffer overflow attack. This is because you pass in the + buffer to be filled in, which has to be of finite length. But in this + Lua module, a buffer is assigned automatically and the function returns + the string, so there is no security issue. You may still use the alternate + functions:

+ + +
+s = stdscr:getnstr()
+s = stdscr:inchnstr()
+s = stdscr:innstr()
+
+ +

which take an extra "size of buffer" argument, in order to impose a maximum + length on the string the user may type in.

+ +

Some of the C functions beginning with "no" do not exist in Lua. You should + use curses.nl(false) and curses.nl(true) instead of nonl() and nl(), + and likewise curses.echo(false) and curses.echo(true) instead of + noecho() and echo() .

+ +

In this Lua module the stdscr:getch() function always returns an integer. + In C, a single character is an integer, but in Lua (and Perl) a single + character is a short string. The Perl Curses function getch() returns a + char if it was a char, and a number if it was a constant; to get this + behaviour in Lua you have to convert explicitly, e.g.:

+ + +
+if c < 256 then c = string.char(c) end
+
+ +

Some Lua functions take a different set of parameters than their C + counterparts; for example, you should use str = stdscr.getstr() and + y, x = stdscr.getyx() instead of getstr(str) and getyx(y, x), and + likewise for getbegyx and getmaxyx and getparyx and pair_content. + The Perl Curses module now uses the C-compatible parameters, so be aware of + this difference when translating code from Perl into Lua, as well as from C + into Lua.

+ +

Many curses functions have variants starting with the prefixes w-, mv-, + and/or wmv-. These variants differ only in the explicit addition of a + window, or by the addition of two coordinates that are used to move the + cursor first. For example, in C addch() has three other variants: + waddch(), mvaddch() and mvwaddch(). The Lua equivalents, + respectively being stdscr:addch(), somewindow:addch(), + stdscr:mvaddch() and somewindow:mvaddch(), with the window argument + passed implicitly with Lua's : syntax sugar.

This is because you pass in the + buffer to be filled in, which has to be of finite length. But in this + Lua module, a buffer is assigned automatically and the function returns + the string, so there is no security issue. You may still use the alternate + functions: + + s = stdscr:getnstr() + s = stdscr:inchnstr() + s = stdscr:innstr() + + which take an extra "size of buffer" argument, in order to impose a maximum + length on the string the user may type in. + + Some of the C functions beginning with "no" do not exist in Lua. You should + use `curses.nl(false)` and `curses.nl(true)` instead of `nonl()` and `nl()`, + and likewise `curses.echo(false)` and `curses.echo(true)` instead of + `noecho()` and `echo()` . + + In this Lua module the `stdscr:getch()` function always returns an integer. + In C, a single character is an integer, but in Lua (and Perl) a single + character is a short string. The Perl Curses function `getch()` returns a + char if it was a char, and a number if it was a constant; to get this + behaviour in Lua you have to convert explicitly, e.g.: + + if c < 256 then c = string.char(c) end + + Some Lua functions take a different set of parameters than their C + counterparts; for example, you should use `str = stdscr.getstr()` and + `y, x = stdscr.getyx()` instead of `getstr(str)` and `getyx(y, x)`, and + likewise for `getbegyx` and `getmaxyx` and `getparyx` and `pair_content`. + The Perl Curses module now uses the C-compatible parameters, so be aware of + this difference when translating code from Perl into Lua, as well as from C + into Lua. + + Many curses functions have variants starting with the prefixes `w-`, `mv-`, + and/or `wmv-`. These variants differ only in the explicit addition of a + window, or by the addition of two coordinates that are used to move the + cursor first. For example, in C `addch()` has three other variants: + `waddch()`, `mvaddch()` and `mvwaddch()`. The Lua equivalents, + respectively being `stdscr:addch()`, `somewindow:addch()`, + `stdscr:mvaddch()` and `somewindow:mvaddch()`, with the window argument + passed implicitly with Lua's `:` syntax sugar. + +@module posix.curses +*/ + + +#include + +#include "curses/chstr.c" +#include "curses/window.c" + + +#if HAVE_CURSES + +#include "_helpers.c" +#include "strlcpy.c" + + +static const char *STDSCR_REGISTRY = "curses:stdscr";

Set up important Lua paths, such as the directories in +# which to install scripts and modules (shared libraries). +# +# Also detect Lua headers and libraries. The Lua version contained in the +# header is checked to match the Lua interpreter version exactly. When +# searching for Lua libraries, the version number is used as a suffix. +# This is done with the goal of supporting multiple Lua installs (5.1 and +# 5.2 side-by-side). +# +# A note on compatibility with previous versions: This file has been +# mostly rewritten for serial 18. Most developers should be able to use +# these macros without needing to modify configure.ac. Care has been taken +# to preserve each macro's behavior, but there are some differences: +# +# 1) AX_WITH_LUA is deprecated; it now expands to the exact same thing as +# AX_PROG_LUA with no arguments. +# +# 2) AX_LUA_HEADERS now checks that the version number defined in lua.h +# matches the interpreter version. AX_LUA_HEADERS_VERSION is therefore +# unnecessary, so it is deprecated and does not expand to anything. +# +# 3) The configure flag --with-lua-suffix no longer exists; the user +# should instead specify the LUA precious variable on the command line. +# See the AX_PROG_LUA description for details. +# +# Please read the macro descriptions below for more information. +# +# This file was inspired by Andrew Dalke's and James Henstridge's +# python.m4 and Tom Payne's, Matthieu Moy's, and Reuben Thomas's ax_lua.m4 +# (serial 17). Basically, this file is a mash-up of those two files. I +# like to think it combines the best of the two! +# +# AX_PROG_LUA: Search for the Lua interpreter, and set up important Lua +# paths. Adds precious variable LUA, which may contain the path of the Lua +# interpreter. If LUA is blank, the user's path is searched for an +# suitable interpreter. +# +# If MINIMUM-VERSION is supplied, then only Lua interpreters with a +# version number greater or equal to MINIMUM-VERSION will be accepted. If +# TOO-BIG-VERSION is also supplied, then only Lua interpreters with a +# version number greater or equal to MINIMUM-VERSION and less than +# TOO-BIG-VERSION will be accepted. +# +# The Lua version number, LUA_VERSION, is found from the interpreter, and +# substituted. LUA_PLATFORM is also found, but not currently supported (no +# standard representation). +# +# Finally, the macro finds four paths: +# +# luadir Directory to install Lua scripts. +# pkgluadir $luadir/$PACKAGE +# luaexecdir Directory to install Lua modules. +# pkgluaexecdir $luaexecdir/$PACKAGE +# +# These paths are found based on $prefix, $exec_prefix, Lua's +# package.path, and package.cpath. The first path of package.path +# beginning with $prefix is selected as luadir. The first path of +# package.cpath beginning with $exec_prefix is used as luaexecdir. This +# should work on all reasonable Lua installations. If a path cannot be +# determined, a default path is used. Of course, the user can override +# these later when invoking make. +# +# luadir Default: $prefix/share/lua/$LUA_VERSION +# luaexecdir Default: $exec_prefix/lib/lua/$LUA_VERSION +# +# These directories can be used by Automake as install destinations. The +# variable name minus 'dir' needs to be used as a prefix to the +# appropriate Automake primary, e.g. lua_SCRIPS or luaexec_LIBRARIES. +# +# If an acceptable Lua interpreter is found, then ACTION-IF-FOUND is +# performed, otherwise ACTION-IF-NOT-FOUND is preformed. If ACTION-IF-NOT- +# FOUND is blank, then it will default to printing an error. To prevent +# the default behavior, give ':' as an action. +# +# AX_LUA_HEADERS: Search for Lua headers. Requires that AX_PROG_LUA be +# expanded before this macro. Adds precious variable LUA_INCLUDE, which +# may contain Lua specific include flags, e.g. -I/usr/include/lua5.1. If +# LUA_INCLUDE is blank, then this macro will attempt to find suitable +# flags. +# +# LUA_INCLUDE can be used by Automake to compile Lua modules or +# executables with embedded interpreters. The *_CPPFLAGS variables should +# be used for this purpose, e.g. myprog_CPPFLAGS = $(LUA_INCLUDE). +# +# This macro searches for the header lua.h (and others). The search is +# performed with a combination of CPPFLAGS, CPATH, etc, and LUA_INCLUDE. +# If the search is unsuccessful, then some common directories are tried. +# If the headers are then found, then LUA_INCLUDE is set accordingly. +# +# The paths automatically searched are: +# +# * /usr/include/luaX.Y +# * /usr/include/lua/X.Y +# * /usr/include/luaXY +# * /usr/local/include/luaX.Y +# * /usr/local/include/lua-X.Y +# * /usr/local/include/lua/X.Y +# * /usr/local/include/luaXY +# +# (Where X.Y is the Lua version number, e.g. 5.1.) +# +# The Lua version number found in the headers is always checked to match +# the Lua interpreter's version number. Lua headers with mismatched +# version numbers are not accepted. +# +# If headers are found, then ACTION-IF-FOUND is performed, otherwise +# ACTION-IF-NOT-FOUND is performed. If ACTION-IF-NOT-FOUND is blank, then +# it will default to printing an error. To prevent the default behavior, +# set the action to ':'. +# +# AX_LUA_LIBS: Search for Lua libraries. Requires that AX_PROG_LUA be +# expanded before this macro. Adds precious variable LUA_LIB, which may +# contain Lua specific linker flags, e.g. -llua5.1. If LUA_LIB is blank, +# then this macro will attempt to find suitable flags. +# +# LUA_LIB can be used by Automake to link Lua modules or executables with +# embedded interpreters. The *_LIBADD and *_LDADD variables should be used +# for this purpose, e.g. mymod_LIBADD = $(LUA_LIB). +# +# This macro searches for the Lua library. More technically, it searches +# for a library containing the function lua_load. The search is performed +# with a combination of LIBS, LIBRARY_PATH, and LUA_LIB. +# +# If the search determines that some linker flags are missing, then those +# flags will be added to LUA_LIB. +# +# If libraries are found, then ACTION-IF-FOUND is performed, otherwise +# ACTION-IF-NOT-FOUND is performed. If ACTION-IF-NOT-FOUND is blank, then +# it will default to printing an error. To prevent the default behavior, +# set the action to ':'. +# +# AX_LUA_READLINE: Search for readline headers and libraries. Requires the +# AX_LIB_READLINE macro, which is provided by ax_lib_readline.m4 from the +# Autoconf Archive. +# +# If a readline compatible library is found, then ACTION-IF-FOUND is +# performed, otherwise ACTION-IF-NOT-FOUND is performed. +# +# LICENSE +# +# Copyright (c) 2015 Reuben Thomas +# Copyright (c) 2014 Tim Perkins +# +# This program is free software: you can redistribute it and/or modify it +# under the terms of the GNU General Public License as published by the +# Free Software Foundation, either version 3 of the License, or (at your +# option) any later version. +# +# This program is distributed in the hope that it will be useful, but +# WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The NcursesW +# (wide-character) library is searched for first, followed by Ncurses, +# then the system-default plain Curses. The first library found is the +# one returned. +# +# The following options are understood: --with-ncursesw, --with-ncurses, +# --without-ncursesw, --without-ncurses. The "--with" options force the +# macro to use that particular library, terminating with an error if not +# found. The "--without" options simply skip the check for that library. +# The effect on the search pattern is: +# +# (no options) - NcursesW, Ncurses, Curses +# --with-ncurses --with-ncursesw - NcursesW only [*] +# --without-ncurses --with-ncursesw - NcursesW only [*] +# --with-ncursesw - NcursesW only [*] +# --with-ncurses --without-ncursesw - Ncurses only [*] +# --with-ncurses - NcursesW, Ncurses [**] +# --without-ncurses --without-ncursesw - Curses only +# --without-ncursesw - Ncurses, Curses +# --without-ncurses - NcursesW, Curses +# +# [*] If the library is not found, abort the configure script. +# +# [**] If the second library (Ncurses) is not found, abort configure. +# +# The following preprocessor symbols may be defined by this macro if the +# appropriate conditions are met: +# +# HAVE_CURSES - if any SysV or X/Open Curses library found +# HAVE_CURSES_ENHANCED - if library supports X/Open Enhanced functions +# HAVE_CURSES_COLOR - if library supports color (enhanced functions) +# HAVE_CURSES_OBSOLETE - if library supports certain obsolete features +# HAVE_NCURSESW - if NcursesW (wide char) library is to be used +# HAVE_NCURSES - if the Ncurses library is to be used +# +# HAVE_CURSES_H - if is present and should be used +# HAVE_NCURSESW_H - if should be used +# HAVE_NCURSES_H - if should be used +# HAVE_NCURSESW_CURSES_H - if should be used +# HAVE_NCURSES_CURSES_H - if should be used +# +# (These preprocessor symbols are discussed later in this document.) +# +# The following output variable is defined by this macro; it is precious +# and may be overridden on the ./configure command line: +# +# CURSES_LIB - library to add to xxx_LDADD +# +# The library listed in CURSES_LIB is NOT added to LIBS by default. You +# need to add CURSES_LIB to the appropriate xxx_LDADD line in your +# Makefile.am. For example: +# +# prog_LDADD = @CURSES_LIB@ +# +# If CURSES_LIB is set on the configure command line (such as by running +# "./configure CURSES_LIB=-lmycurses"), then the only header searched for +# is . The user may use the CPPFLAGS precious variable to +# override the standard #include search path. If the user needs to +# specify an alternative path for a library (such as for a non-standard +# NcurseW), the user should use the LDFLAGS variable. +# +# The following shell variables may be defined by this macro: +# +# ax_cv_curses - set to "yes" if any Curses library found +# ax_cv_curses_enhanced - set to "yes" if Enhanced functions present +# ax_cv_curses_color - set to "yes" if color functions present +# ax_cv_curses_obsolete - set to "yes" if obsolete features present +# +# ax_cv_ncursesw - set to "yes" if NcursesW library found +# ax_cv_ncurses - set to "yes" if Ncurses library found +# ax_cv_plaincurses - set to "yes" if plain Curses library found +# ax_cv_curses_which - set to "ncursesw", "ncurses", "plaincurses" or "no" +# +# These variables can be used in your configure.ac to determine the level +# of support you need from the Curses library. For example, if you must +# have either Ncurses or NcursesW, you could include: +# +# AX_WITH_CURSES +# if test "x$ax_cv_ncursesw" != xyes && test "x$ax_cv_ncurses" != xyes; then +# AX_MSG_ERROR([requires either NcursesW or Ncurses library]) +# fi +# +# If any Curses library will do (but one must be present and must support +# color), you could use: +# +# AX_WITH_CURSES +# if test "x$ax_cv_curses" != xyes || test "x$ax_cv_curses_color" != xyes; then +# AC_MSG_ERROR([requires an X/Open-compatible Curses library with color]) +# fi +# +# Certain preprocessor symbols and shell variables defined by this macro +# can be used to determine various features of the Curses library. In +# particular, HAVE_CURSES and ax_cv_curses are defined if the Curses +# library found conforms to the traditional SysV and/or X/Open Base Curses +# definition. Any working Curses library conforms to this level. +# +# HAVE_CURSES_ENHANCED and ax_cv_curses_enhanced are defined if the +# library supports the X/Open Enhanced Curses definition. In particular, +# the wide-character types attr_t, cchar_t and wint_t, the functions +# wattr_set() and wget_wch() and the macros WA_NORMAL and _XOPEN_CURSES +# are checked. The Ncurses library does NOT conform to this definition, +# although NcursesW does. +# +# HAVE_CURSES_COLOR and ax_cv_curses_color are defined if the library +# supports color functions and macros such as COLOR_PAIR, A_COLOR, +# COLOR_WHITE, COLOR_RED and init_pair(). These are NOT part of the +# X/Open Base Curses definition, but are part of the Enhanced set of +# functions. The Ncurses library DOES support these functions, as does +# NcursesW. +# +# HAVE_CURSES_OBSOLETE and ax_cv_curses_obsolete are defined if the +# library supports certain features present in SysV and BSD Curses but not +# defined in the X/Open definition. In particular, the functions +# getattrs(), getcurx() and getmaxx() are checked. +# +# To use the HAVE_xxx_H preprocessor symbols, insert the following into +# your system.h (or equivalent) header file: +# +# #if defined HAVE_NCURSESW_CURSES_H +# # include +# #elif defined HAVE_NCURSESW_H +# # include +# #elif defined HAVE_NCURSES_CURSES_H +# # include +# #elif defined HAVE_NCURSES_H +# # include +# #elif defined HAVE_CURSES_H +# # include +# #else +# # error "SysV or X/Open-compatible Curses header file required" +# #endif +# +# For previous users of this macro: you should not need to change anything +# in your configure.ac or Makefile.am, as the previous (serial 10) +# semantics are still valid. However, you should update your system.h (or +# equivalent) header file to the fragment shown above. You are encouraged +# also to make use of the extended functionality provided by this version +# of AX_WITH_CURSES, as well as in the additional macros +# AX_WITH_CURSES_PANEL, AX_WITH_CURSES_MENU and AX_WITH_CURSES_FORM. +# +# LICENSE +# +# Copyright (c) 2009 Mark Pulford +# Copyright (c) 2009 Damian Pietras +# Copyright (c) 2012 Reuben Thomas +# Copyright (c) 2011 John Zaitseff +# +# This program is free software: you can redistribute it and/or modify it +# under the terms of the GNU General Public License as published by the +# Free Software Foundation, either version 3 of the License, or (at your +# option) any later version. +# +# This program is distributed in the hope that it will be useful, but +# WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
