In addition to " #pragma", " #error" should also be granted
an exception, since the unindented form would be rejected by
pre-ANSI C preprocessors.
From Karl Heuer
Write documentation
Include an example explaining how to use cppi as part of a cvs commit hook.
Add overwrite option -- maybe use GNU-style backup code.
Suggestion from Ulrich Drepper:
Add an option to convert code like this, removing unnecessary
parentheses and adding any spaces required to replace them:
#if defined(FOO) || !defined (BAR)
to this:
#if defined FOO || !defined BAR
Allow regex filtering (use Henry Spencer's new perl-like regexps)
rather than hard-coding test for .c and .h suffixes
Add an option to enable the following (there's already support for it):
Uli's suggestion for setting initial indentation level to e.g. -1
for header files bracketed with #ifdef FOO_H/#define FOO_H...#endif.
Make sure we get a reasonable failure when cppi.l is modified
and flex is not available.
Likewise with cpp.gp and gperf (do this via the `missing' script).
Currently, the indentation width is hard-coded
at one space per nesting level. Add an option to change that.
Add an option to tell cppi to ignore file-spanning directives like these:
#ifndef FOO_H
#define FOO_H
...
#endif FOO_H
