Usage of crackfortran:
======================
Command line keys: -quiet,-verbose,-fix,-f77,-f90,-show,-h <pyffilename>
-m <module name for f77 routines>,--ignore-contains
Functions: crackfortran, crack2fortran
The following Fortran statements/constructions are supported
(or will be if needed):
block data,byte,call,character,common,complex,contains,data,
dimension,double complex,double precision,end,external,function,
implicit,integer,intent,interface,intrinsic,
logical,module,optional,parameter,private,public,
program,real,(sequence?),subroutine,type,use,virtual,
include,pythonmodule
Note: 'virtual' is mapped to 'dimension'.
Note: 'implicit integer (z) static (z)' is 'implicit static (z)' (this is minor bug).
Note: code after 'contains' will be ignored until its scope ends.
Note: 'common' statement is extended: dimensions are moved to variable definitions
Note: f2py directive: <commentchar>f2py<line> is read as <line>
Note: pythonmodule is introduced to represent Python module
Usage:
`postlist=crackfortran(files,funcs)`
`postlist` contains declaration information read from the list of files `files`.
`crack2fortran(postlist)` returns a fortran code to be saved to pyf-file
`postlist` has the following structure:
*** it is a list of dictionaries containing `blocks':
B = {'block','body','vars','parent_block'[,'name','prefix','args','result',
'implicit','externals','interfaced','common','sortvars',
'commonvars','note']}
B['block'] = 'interface' | 'function' | 'subroutine' | 'module' |
'program' | 'block data' | 'type' | 'pythonmodule'
B['body'] --- list containing `subblocks' with the same structure as `blocks'
B['parent_block'] --- dictionary of a parent block:
C['body'][<index>]['parent_block'] is C
B['vars'] --- dictionary of variable definitions
B['sortvars'] --- dictionary of variable definitions sorted by dependence (independent first)
B['name'] --- name of the block (not if B['block']=='interface')
B['prefix'] --- prefix string (only if B['block']=='function')
B['args'] --- list of argument names if B['block']== 'function' | 'subroutine'
B['result'] --- name of the return value (only if B['block']=='function')
B['implicit'] --- dictionary {'a':<variable definition>,'b':...} | None
B['externals'] --- list of variables being external
B['interfaced'] --- list of variables being external and defined
B['common'] --- dictionary of common blocks (list of objects)
B['commonvars'] --- list of variables used in common blocks (dimensions are moved to variable definitions)
B['from'] --- string showing the 'parents' of the current block
B['use'] --- dictionary of modules used in current block:
{<modulename>:{['only':<0|1>],['map':{<local_name1>:<use_name1>,...}]}}
B['note'] --- list of LaTeX comments on the block
B['f2pyenhancements'] --- optional dictionary
{'threadsafe':'','fortranname':<name>,
'callstatement':<C-expr>|<multi-line block>,
'callprotoargument':<C-expr-list>,
'usercode':<multi-line block>|<list of multi-line blocks>,
'pymethoddef:<multi-line block>'
}
B['entry'] --- dictionary {entryname:argslist,..}
B['varnames'] --- list of variable names given in the order of reading the
Fortran code, useful for derived types.
B['saved_interface'] --- a string of scanned routine signature, defines explicit interface
*** Variable definition is a dictionary
D = B['vars'][<variable name>] =
{'typespec'[,'attrspec','kindselector','charselector','=','typename']}
D['typespec'] = 'byte' | 'character' | 'complex' | 'double complex' |
'double precision' | 'integer' | 'logical' | 'real' | 'type'
D['attrspec'] --- list of attributes (e.g. 'dimension(<arrayspec>)',
'external','intent(in|out|inout|hide|c|callback|cache|aligned4|aligned8|aligned16)',
'optional','required', etc)
K = D['kindselector'] = {['*','kind']} (only if D['typespec'] =
'complex' | 'integer' | 'logical' | 'real' )
C = D['charselector'] = {['*','len','kind']}
(only if D['typespec']=='character')
D['='] --- initialization expression string
D['typename'] --- name of the type if D['typespec']=='type'
D['dimension'] --- list of dimension bounds
D['intent'] --- list of intent specifications
D['depend'] --- list of variable names on which current variable depends on
D['check'] --- list of C-expressions; if C-expr returns zero, exception is raised
D['note'] --- list of LaTeX comments on the variable
*** Meaning of kind/char selectors (few examples):
D['typespec>']*K['*']
D['typespec'](kind=K['kind'])
character*C['*']
character(len=C['len'],kind=C['kind'])
(see also fortran type declaration statement formats below)
Fortran 90 type declaration statement format (F77 is subset of F90)
====================================================================
(Main source: IBM XL Fortran 5.1 Language Reference Manual)
type declaration = <typespec> [[<attrspec>]::] <entitydecl>
<typespec> = byte |
character[<charselector>] |
complex[<kindselector>] |
double complex |
double precision |
integer[<kindselector>] |
logical[<kindselector>] |

<charselector> = * <charlen> |
([len=]<len>[,[kind=]<kind>]) |
(kind=<kind>[,len=<len>])
<kindselector> = * <intlen> |
([kind=]<kind>)
<attrspec> = comma separated list of attributes.
Only the following attributes are used in
building up the interface:
external
(parameter --- affects '=' key)
optional
intent
Other attributes are ignored.
<intentspec> = in | out | inout
<arrayspec> = comma separated list of dimension bounds.
<entitydecl> = <name> [[*<charlen>][(<arrayspec>)] | [(<arrayspec>)]*<charlen>]
[/<init_expr>/ | =<init_expr>] [,<entitydecl>]
In addition, the following attributes are used: check,depend,note
TODO:
* Apply 'parameter' attribute (e.g. 'integer parameter :: i=2' 'real x(i)'
-> 'real x(2)')
The above may be solved by creating appropriate preprocessor program, for example.
