blackb1rd changed the title from C : Can't parsing function after macro line to C : Can't parse function after macro line Jul 5, 2015 Universal Ctags member masatake commented Mar That ticket has more discussion already. Use Cil.GFun to find out about functions and their locations with respect to the pragmas. Input stream must be hacked.

ROSE is implemented largely in C++; DMS is self-implemented using PARLANSE (a parallel programming language) and a set of DSLs. The same effect could be achieved using macros, for example #define DO_PRAGMA(x) _Pragma (#x) DO_PRAGMA (GCC dependency "parse.y") The standard is unclear on where a _Pragma operator can appear.

If you have to analyze the code to determine what to insert and where to insert it, you have far more work to do. https://sourceforge.net/p/cil/mailman/message/1237836/ We seem to both have good flow analyzers for C. This considerably simplifies the (post-)processing of the functions. >maybe I should modify CIL. ntrel commented Feb 2, 2015 Perhaps you could use ctags -I 'PRAGMA+' to skip the macro expansion part.

That way the file is more "portable" and external tools (like stylish-haskell) can read it more easily.
Is there a reason not to just always accept/parse both UnicodeSyntax and non-UnicodeSyntax source? If your intention is to automate permanent code changes, ROSE can make this hard: how will it retain comments in the resulting code, if it throws them away as it parses? What movie is this? http://fortecrm.net/cannot-parse/cannot-parse-text.html stylish-haskell owner jaspervdj commented Jul 7, 2016 Parsing language extensions from the cabal file is a bit outside of the scope of this project, in my opinion.

Which compiler framework is the easiest to do such a task.
Our DMS Software Reengineering Toolkit with its C Front End can probably do what you want. If the pragma conceptually is an attribute of the function, I prefer to attach the pragma to the function as a GNU-style attribute (Cil.addAttribute). UnicodeSyntax would definitely be part of that. 👍 1 siddharthist changed the title from Parse failed on UnicodeSyntax file without UnicodeSyntax pragma to Allow parsing certain language extensions when pragma Related 1How to manipulate C# AST?1973Improve INSERT-per-second performance of SQLite?6Recommend C front-end that preserves preprocessor directives2544Flash CS4 refuses to let go88What kinds of patterns could I enforce on the code to
They are documented in the GCC manual. They are not recognized with the GCC prefix. See Obsolete Features. http://fortecrm.net/cannot-parse/cannot-parse-hex-bytes.html From: George Necula - 2006-05-02 06:04:36 Indeed, CIL supports #pragmas only at global scope.
Note that CIL does not associate the pragma with the function. Regex works on strings. It is destringized, by replacing all ‘\\’ with a single ‘\’ and all ‘\"’ with a ‘"’. If what I said above won't work out for You, hack the sources of CIL and recompile. (You need an OCaml development system for that; but if You venture that far,

Retention means you don't get a symbol table. Could it also detect it from the cabal file?
To enforce this, you can poison the identifier with this pragma. #pragma GCC poison is followed by a list of identifiers to poison. This is in line with the STDC prefix on all pragmas defined by C99.
