Cause the tool(s) built by this package to be used also when running

commands via e.g., "make syntax-check". Doing this a little sooner

would have avoided a grep infloop bug.

export PATH := $(builddir)/src$(PATH_SEPARATOR)$(PATH)

Used in maint.mk's web-manual rule

manual_title = GNU Grep: Print lines matching a pattern

Use the direct link. This is guaranteed to work immediately, while

it can take a while for the faster mirror links to become usable.

Tools used to bootstrap this package, used for "announcement".

Override the default Cc: used in generating an announcement.

The tight_scope test gets confused about inline functions.

like 'to_uchar'.

Now that we have better tests, make this the default.

Comparing tarball sizes compressed using different xz presets, we see

that -6e adds only 60 bytes to the size of the tarball, yet reduces

(from -9) the decompression memory requirement from 64 MiB to 9 MiB.

Don't be tempted by -5e, since -6 and -5 use the same dictionary size.

Many m4 macros names once began with 'jm_'.

Make sure that none are inadvertently reintroduced.

sc_prohibit_jm_in_m4: @grep -nE 'jm_[A-Z]' \ $$($(VC_LIST) m4 |grep '.m4$$'; echo /dev/null) && \ { echo '$(ME): do not use jm_ in m4 macro names' \ 1>&2; exit 1; } || :

sc_prohibit_echo_minus_en: @prohibit='\<echo -[en]' \ halt='do not use echo ''-e or echo ''-n; use printf instead' \ $(_sc_search_regexp)

Look for lines longer than 80 characters, except omit:

- program-generated long lines in diff headers,

- the help2man script copied from upstream,

- tests involving long checksum lines, and

- the 'pr' test cases.

LINE_LEN_MAX = 80 FILTER_LONG_LINES = \ /^[^:].diff:[^:]:@@ / d; \ |^[^:]TODO:| d; \ |^[^:]man/help2man:| d; \ |^[^:]tests/misc/sha[0-9]sum..pl[-:]| d; \ |^[^:]tests/pr/|{ |^[^:]*tests/pr/pr-tests:| !d; }; sc_long_lines: @files=$$($(VC_LIST_EXCEPT)) \ halt='line(s) with more than $(LINE_LEN_MAX) characters; reindent'; \ for file in $$files; do \ expand $$file | grep -nE '^.{$(LINE_LEN_MAX)}.' | \ sed -e "s|^|$$file:|" -e '$(FILTER_LONG_LINES)'; \ done | grep . && { msg="$$halt" $(_sc_say_and_exit) } || :

Indent only with spaces.

sc_prohibit_tab_based_indentation: @prohibit='^ * ' \ halt='TAB in indentation; use only spaces' \ $(_sc_search_regexp)

Don't use "indent-tabs-mode: nil" anymore. No longer needed.

sc_prohibit_emacs__indent_tabs_mode__setting: @prohibit='^( [#] *)?indent-tabs-mode:' \ halt='use of emacs indent-tabs-mode: setting' \ $(_sc_search_regexp)

Ensure that the list of test file names in tests/Makefile.am is sorted.

sc_sorted_tests: @perl -0777 -ne \ '/^TESTS =(.*?)^$$/ms; ($$t = $$1) =~ s/[\\s\n]+/\n/g;print $$t' \ tests/Makefile.am | sort -c

THANKS.in is a list of name/email pairs for people who are mentioned in

commit logs (and generated ChangeLog), but who are not also listed as an

author of a commit. Name/email pairs of commit authors are automatically

extracted from the repository. As a very minor factorization, when

someone who was initially listed only in THANKS.in later authors a commit,

this rule detects that their pair may now be removed from THANKS.in.

sc_THANKS_in_duplicates: @{ git log --pretty=format:%aN | sort -u; \ cut -b-36 THANKS.in | sed '/^$$/d;s/ *$$//'; } \ | sort | uniq -d | grep . \ && { echo '$(ME): remove the above names from THANKS.in' \ 1>&2; exit 1; } || :

Ensure that tests don't use cmd ... && fail=1 as that hides crashes.

The "exclude" expression allows common idioms like test ... && fail=1

and the 2>... portion allows commands that redirect stderr and so probably

independently check its contents and thus detect any crash messages.

sc_prohibit_and_fail_1: @prohibit='&& fail=1' \ exclude='(stat|kill|test |EGREP|grep|compare|2> *[^/])' \ halt='&& fail=1 detected. Please use: returns_ 1 ... || fail=1' \ in_vc_files='^tests/' \ $(_sc_search_regexp)
