Cannot Parse Language Pragma

Linked 1 How can insert pragmas above some functions in my C code 2 How can I get the function name as text not string in a macro? Tell us about it. That ticket has more discussion already. Why is this C++ code faster than my hand-written assembly for testing the Collatz conjecture? weblink

I'd say we should add StandaloneDeriving to the list 😄 I think that ultimately, stylish-haskell can't really have http://en.wikipedia.org/wiki/Regular_expression share|improve this answer answered Jun 9 '12 at 13:07 Superman 2,523178 Regular expressions can't really parse C reliably. –Ira Baxter Jun 9 '12 at 17:49 I

Please don't fill out this field. DMS can parse, build ASTs, and carry out custom transformations on source text, either procedural or as a surface syntax transform. Reload to refresh your session. https://ghc.haskell.org/trac/ghc/ticket/3396 However, I always recommend putting all the extensions on top of the file.

Cil.GFun is a member of type Cil.global, too. To enforce this, you can poison the identifier with this pragma. #pragma GCC poison is followed by a list of identifiers to poison.

The message contained in the pragma must be a single string literal. Sorry!

Note that CIL does not associate the pragma with the function. Note that the same function parses OPTION pragmas, which do work correctly even if they fall on a 1024-byte boundary. New description: A language pragma like {{{ {-# LANGUAGE TypeOperators, FlexibleContexts #-} }}} parses just fine but {{{ {-# LANGUAGE TypeOperators, FlexibleContexts #-} }}} doesn't, saying: {{{ Cannot parse LANGUAGE pragma check over here Could it also detect it from the cabal file?

Adding still more breaks it again as soon as the 2048th byte is among the contents of the {-# #-}, so this is indeed an alignment issue.

DMS's C++ flow analysis is limited to control flow at the moment but we're pushing to dataflow; dunno if Rose does any C++ data flow. –Ira Baxter Jun 9 '12 at I'm not familiar enough with the system to be able to fix it, but it seems to me that modifying the definition of parseLanguage (in the where clause) somehow should suffice. Other pragmas are meaningful to the C or C++ compilers. this content masatake added this to the Feature plan milestone Dec 25, 2014 Universal Ctags member masatake commented Dec 25, 2014 Private note: We have to record the macro definition in directiveDefine of

I think ROSE does poorly with processing and retaining comments, because it uses the EDG compiler front end, that throws away comments just as most compiler front ends do. New description: Language pragmas like {{{ {-# LANGUAGE TypeOperators, FlexibleContexts #-} }}} or {{{ {-# LANGUAGE TypeOperators, FlexibleContexts #-} }}} parse just fine but {{{ {-# LANGUAGE TypeOperators, FlexibleContexts #-} }}} Type Cil.global grants access to the pragmas' contents via Cil.GPragma. They are not recognized with the GCC prefix.
