2009-06-26undefine() leaves the hash entry for the macro (for use by builtin()) andPhilip Guenthe
only deletes the definition; macro_for_all needs to skip those to keep dumpdef() from segving ok and regress test by espie (thanks!)
2009-02-08bump the posix reference in STANDARDS to IEEE Std 1003.1-2008, with a fewJason McIntyre
updates to follow;
2008-08-22kill trailing whitespace;Jason McIntyre
2008-08-21Document new gnu extensions, okay jmc@, otto@Marc Espie
2008-08-21in gnu-m4 mode, allow definition of the empty macro (yes, autoconf 2.62Marc Espie
actually uses this, bleh) okay otto@
2008-08-21extend format support to cater to recent GNU autoconfMarc Espie
okay otto@, some useful ideas from miod@
2008-08-21gnu extension: 0rN:az for baseN numbers.Marc Espie

2008-08-16revert eval.cMarc Espie
2008-08-16not yet, committed too muchMarc Espie
2008-08-16argument parsing should only skip spaces outside of parenthesis.Marc Espie
Inside matching parenthesis, keep spaces as is (use chrsave instead of pbstr, since there's no way it can be a further macro expansion). Fixes a long-standing issue with autoconf ( --option -> --option), matches other m4 than gnum4 okay millert@, fries@
2008-08-16be more liberal in include handling, namely we only error out if it'sMarc Espie
the end of the last included file AND we still have a macro to expand. autoconf uses this in wine, and it turns out other m4 also do things that way (not only gnu m4). okay fries@, millert@

2005-09-06finally make our m4 SusV3-compliant.Marc Espie
- changecom and changequote have a simple definition (that matches gnu-m4, coincidentally, so we no longer need two distinct modes for these) - off-by-one bug in -s, this finally works. - reorder main parser loop, so that we can use alphabetic constructs in quotes/comments. - rename putback to pushback, this matches comments, and makes more sense. - more uniform (and updated) description of changequote/changecom. - new, systematic regression tests of comments/quotes. - framework to test -s: one perl script to reconstitute `full' files with all line numbers, so that we can verify the output without needing a complete match. okay otto@, fries@
2005-08-06zap rcsid. It's not ramdisk, but they still take space.Marc Espie
2005-05-29fix a few minor compatibility issues.Marc Espie
- let eval() handle a base and number of digits, like it's advertized to. - in gnu-mode, undivert can take file names as arguments. - in gnu-mode, map can handle reversed charsets. Suggestions and okay otto@, mostly prompted by looking at the regress tests in newer gnu-m4.
2005-05-21more heuristics to coerce gnu-m4 mode to work like we wish: if a ^ or $Marc Espie
is seen in the regexp, this means we need to take new lines into account. Otherwise, we don't.

2004-05-12replace hand-made expr() parser with a lex/yacc affair that is shorter,Marc Espie
