2004-05-12all numbers as one composite regexp.Marc Espie
2004-05-12replace hand-made expr() parser with a lex/yacc affair that is shorter,Marc Espie
easier to understand and extend, and better conformant to Single Unix 3 (especially doing all arithmetic as int32_t). Comments and approval millert@, otto@, fries@
2004-02-17Change the maketemp() description into what it really does.Miod Vallat
ok espie@ jmc@
2004-02-01add paper.txt target;Jason McIntyre
remove explicit paper.ps target, since it's already built by default; (this paper not installed yet)
2003-11-22the the typo. from rohee@Marc Espie
2003-11-17Modify xalloc so that it also takes err(3)-like arguments.Marc Espie
Write an xrealloc wrapper that works the same way, and use it as well. People who feel like it may want to add more explicit error messages to all the places m4 can fail allocating memory... okay tedu@
2003-06-30Fold trace status into the single hash table that's left.Marc Espie
Inline some macros/functions for speed. So, this achieves the goal of one single lookup for macro/trace status, which does speed up m4 in partial tracing situations somewhat. This does also speed up m4 in large pushdef situations, since it no longer has to lookup large chains of macros. okay millert@
2003-06-30add a flag for each macro name that records built-in status.Marc Espie
Fold built-in lookup into normal lookup. okay millert@
2003-06-30replace old hash structure with open hashing.Marc Espie
make the stack structure of macro definitions explicit. okay millert@
2003-06-30Make the trace status of a macro an actual argument that gets pushedMarc Espie
in the frame for the macro expansion. (This will allow one single lookup to grab the macro definition and the trace status) okay millert@
2003-06-30clean up internal lookup interface:Marc Espie
define an interface with explicit define/pushdef/popdef... and use it. That way, most details of the hashtable are no longer visible. okay millert@
2003-06-29Explain in more details how define interacts with pushdef/popdef, andMarc Espie
how that varies from an m4 implementation to another. ok jmc@
2003-06-27- replace .Ql with .Sq; this was also causing a problem with postscriptJason McIntyre
- escape ampersand - missing full stop fixes from wiz@netbsd

2003-06-18- store builtin name as definition for builtin macros.Marc Espie
this removes the need for code->name conversion, in exchange for systematically testing the definition type, since we can no longer rely on the defn being NULL. - commonnalize the builtin-detection code, so that we can use it for pushdef as well with define, so that pushdef handles builtins correctly as well. okay fries@, millert@.
2003-06-12switch from linked list to hash table for traced macros.Marc Espie
speeds up recent autoconf somewhat, since it traces a large set of individual macro. (more rework of m4 internal interfaces to unify lookup tables in order) okay fries@
2003-06-10mostly ansi cleanup; pval okTheo de Raadt
2003-06-10- section reorderJason McIntyre
- COMPATIBILITY merge - macro cleanup - kill whitespace at EOL - new sentence, new line ssh pages ok markus@
2003-06-08Better argv tests, enough to fix autoconf 2.57, apparently.Marc Espie
okay millert@
2003-06-08Let patsubst handle empty patterns: those match anywhere, and don'tMarc Espie
replace any character. Like gnu-m4 does, and other regexp languages do. okay fries@
2003-06-07Show filename and line number in regexp error.Marc Espie
Okay fries@
2003-06-03Remove the advertising clause in the UCB license which BerkeleyTodd C. Miller
rescinded 22 July 1999. Proofed by myself and Theo.
2003-04-14built in -> built-in;Jason McIntyre
from NetBSD (Igor Sobrado); smrsh(8) passed on to sendmail people; ok millert@
2003-04-05say goodbye to strcpy, okay deraadt@Marc Espie

2003-02-16Forgot to document -o, somehow.Marc Espie
2003-01-07.Sq -> .QlMike Pechkin
Make sence. Spotted by jmc@acn.waw.pl pvalchev@, millert@
2003-01-05Grammar and typo fixes, general language improvementsPeter Valchev
from jmc@prioris.mini.pw.edu.pl with changes by me
2002-04-28Implement -s.Marc Espie
Triggered by recent FreeBSD changes. - emits #line directives at every file change (like FreeBSD) - maintains a synch_lineno variable to verify when the output gets out of synch with the input, so that it can emit #line to re-synch as well (unlike FreeBSD) To do: either handle \end-of-line, or recognize when a macro expansion is in progress, so that line synch don't perturb cpp on multi-line expansions. With this, we should have a fully POSIX-compliant m4. ok miod@
2002-04-26use ansi function declarations. ok millert@Marc Espie
2002-04-26prototype mismatch, ansi conversion rules...Marc Espie
add -pedantic to flags.
2002-04-26fix indentation errorMarc Espie
2002-04-26rename `bool' to something else, to avoid C99 surprises.Marc Espie
2002-04-22Do not hardcode mvme88k-specific compilation flags here, especially sinceMiod Vallat
the new flags happen to be no different from those set in <sys.mk>
2002-04-18correct description of undefine, both according to the code, and toMarc Espie
single unix.
2002-02-16Part one of userland __P removal. Done with a simple regexp with some minor ↵Todd C. Miller
hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.
2001-12-28Kill yet another hardcoded size. Ok fries@Marc Espie
and flush(stdout) on debugging mode, as a vicious coredump can leave you without info otherwise.
2001-11-16incorrect writeTheo de Raadt
2001-10-13Resize buffer correctly, I'm an idiot.Marc Espie
Found by fries@, ok deraadt@
2001-10-10Handle macro expansion even if argc==2, which can happen in indir() calls.Marc Espie
Problem encountered by obecian@.
2001-10-10Prototypes shouldn't mention argument name.Marc Espie
2001-10-10Quote filename properly.Marc Espie
2001-10-10Fix indentMarc Espie
2001-10-06This PUTBACK must be protected against EOF. The others are fine.Marc Espie
2001-09-29show level of macro expansion, not dummy 1 (finally found some gnu-m4Marc Espie
scripts where that level != 1, hard to test otherwise...) Put a space after comma. Both these make trace output much closer to gnu-m4 output for debugging purposes.
2001-09-29Synchronize comment with reality.Marc Espie
In gnu-m4 mode, pass the real number of arguments to changequote/changecom, since those distinguish changequote() from changequote.
2001-09-29document tracing and compatibility with other m4.Marc Espie
2001-09-28Remove debugging scaffoldingMarc Espie
2001-09-28more emacs regexps in -g mode. Ok millert@Marc Espie
With this, some autoconf 2.52 scripts are now working completely.
