up of patching it away in various autoconf derivatives.

before the error message. Use it to simplify code.

- 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.

- 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.

is seen in the regexp, this means we need to take new lines into account.
Otherwise, we don't.

based on Noah Misch's bug report.
okay otto, jmc.

wanted output; from Andreas Burmester <buster_hh@gmx.net>

on div or mod by zero, print error message instead.
ok espie@

Leave out the changed description of changecom/changequote for later.
|
|
|
|
easier to understand and extend, and better conformant to Single Unix 3
(especially doing all arithmetic as int32_t).

remove explicit paper.ps target, since it's already built by default;
(this paper not installed yet)
|

|
|
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@

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@
|
|
Fold built-in lookup into normal lookup.
okay millert@
|
|
make the stack structure of macro definitions explicit.
okay millert@
|
|
in the frame for the macro expansion.
(This will allow one single lookup to grab the macro definition and
the trace status)
okay millert@
|
|
define an interface with explicit define/pushdef/popdef... and use it.
That way, most details of the hashtable are no longer visible.
okay millert@
|
|
how that varies from an m4 implementation to another.
ok jmc@
|
|
- escape ampersand
- missing full stop
fixes from wiz@netbsd
|
|
|

|
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@.
|
|
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@
|
|
|
|
- COMPATIBILITY merge
- macro cleanup
- kill whitespace at EOL
- new sentence, new line

replace any character.
Like gnu-m4 does, and other regexp languages do.
