Subject [jira] Updated: (LUCY-71) Remove Perl dependency of METAQUOTE
Date Sat, 21 Nov 2009 21:20:39 GMT


Marvin Humphrey updated LUCY-71:

    Attachment: charm_and_harm_to_c_and_h.diff

With commit r882993, I svn moved all .charm/.harm files to .c/.h and patched
the metaquote utility and to handle the new filenames.

This gets us past stage one of this issue.

> Charmonizer currently uses a Perl script 'METAQUOTE' to preprocess its '.charm' files
into '.c' files and '.harm' files into '.h' files.   This works, but requires a dependency
on Perl that seems inappropriate for a C language tool.
> The suggested alternatives were to use manual quoting or standard macros.  
> Manual quoting seemed error prone and cumbersome, so this patch proposes the using the
'stringify' (#expr) function within standard C preprocessor macros.
