1999-12-21Recursive definitions are not the real problem.Marc Espie
Trying to expand them is. So flag obvious recursive definitions for later, and give an error only if we expand them. (Some gnu-m4 files, including autoconf, do define some macros with themselves as the replacement text, for use in test-if-set patterns) Since type is no longer MACRTYPE, those macros end up in builtins... but this is not a problem, since expanding them is an error.
1999-11-30Recognizes comments while parsing macros arguments, as every otherMarc Espie
m4 implementation does (including DEC/OSF, Solaris, HP/UX, Aix, and gnu-m4). Checked with millert@.
1999-11-30Clean up comment/quote recognition a little bit:Marc Espie
- use strlcpy to make clear that the strings are line terminated, - remove the number of magic constants, - use assert() for preconditions, - use puts instead of looping over array of chars...

o Add a missing 'unsigned' to 'h' in remhash() o Say 'unsigned int' not just 'unsigned'
1999-11-20Optimization: cache the hashed value to avoid negative comparisons.Marc Espie
With 2^32 possible hash values, this means that collisions no longer incur supplementary string compares, which was most of the reason for STREQ in the first place...
1999-11-17Turn warnings on,Marc Espie
Add missing prototypes, Make local functions static, Sort extern.h by file, Constify all char * that can be, Copy temp file name so that eval does not modify its arguments.

repairs patterns such as divert(6) divert(7) undivert(6) divert(6) which are not that frequent, but were *quite* thoroughly broken...

Bug found by dugsong@. I can't believe it wasn't found before.

Noticed by aaron@.
1999-09-14Style: kill register and indent properly.Marc Espie
Let indx match netbsd flavor, to simplify diffs. Show how many quotes were not closed. Increase stack slightly, now that we're no longer bound by argspace.
1999-09-14-I works better when activated...Marc Espie
Fuss with prototypes.
1999-09-14Add support for hex constants.Marc Espie
Not the same code as NetBSD.

1999-09-06Remove STRSPACE limitations.Marc Espie
A bit wasteful, but not too intrusive. Also remove pushback buffer limitations, as this would be mostly useless otherwise. Incidentally, pushback buffer overflow detection in pbstr was wrong.
1999-09-06Use EOS pervasively.Marc Espie
1999-09-06Get rid of mktemp in the handling of diversion.Marc Espie
Simply put, mkstemp/unlink/rewind has the proper semantics under Unix, and so we don't have to keep track about temp file names and remove them.

1997-12-10cgd: add a typedef which describes elements in the push-back buffer. MakeTheo de Raadt
that typedef 'short'. 'char' (which was previously used) because char may be unsigned and ((char)EOF) != EOF if that is the case. That was causing the (char)EOF (0xff) pushed back in main to be interepreted as a character, and, in some cases, to be written to the output. 'short' was used rather than 'signed char' because if the latter is used, 0xff characters in the input would confuse m4. (No point in introducing (more?) 8-bit lossage.)
