Distribute .all_stamp. + + * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION + to diversion/DIVERSION, this was a spelling error. + + * m4.c: Declare version[], remove #include "version.h". + * version.h: Deleted. + * Makefile.in: Remove references to version.h. + + * output.c (shipout_text): Centralize all `#line NUM ["FILE"]' + production, by using a simpler and more robust algorithm.

Also rename false to FALSE + and true to TRUE. + + * lib/Makefile.in (Makefile): New goal. + + * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not + so heavily loaded. It gets more easily overridable, calling make. + Reported by Jim Meyering. + + * Makefile.in (dist): Get .fname from the current directory name, + instead of from version.h. I need updating many files manually, + when the version changes, version.h is just one of them. + +1992-11-14 François Pinard <pinard@iro.umontreal.ca> + + * m4.h: Remove the tag `boolean' on the enum introducing typedef + `boolean'. This tag conflicts with <sys/types.h> on SVR4. + Reported by Tom McConnell. + +1992-11-13 François Pinard <pinard@iro.umontreal.ca> + + * m4.texinfo: Correct the examples for 33.divert, 38.divnum, + 39.cleardiv, which were describing missing or spurious newlines. + Modify examples 52.eval, 53.esyscmd and 54.sysval so the results + do not depend on machine word size, `/bin/false' implementation, + or `wc' output format. `make check' is more dependable, now. + + * checks/check_them: Summarize the failed tests by listing their + name, at end.

Currently it has +only been certified to work under Linux 2.0. + +Dynamic modules are only available if GNU m4 was configured with +--with-modules and if the dlopen(3) interface is available in the +operating system. + +Implementation details are in ../src/module.c + +A module is a compiled shared object, i.e., modules are written in C and +then compiled. The compiled file can then be loaded into a running m4 +process by calling the builtin "loadmodule". This will give GNU m4 +access to any system feature with a C interface. + +Modules are searched for in M4MODPATH, if set, and in a module directory +defined at configure time, default /usr/local/libexec/m4. + +A module extends GNU m4 by defining new builtins, It can define builtins +with the same names as existing builtins, which will then be +unavailable. A module cannot redefine internal functions of GNU m4, +such as the input parser or argument handling. + +The infrastructure for writing and compiling modules is still a bit +wanting. + +Each module should include the two header files ../src/m4.h and +../src/builtin.h. These will include <ctype.h>, <stdio.h>, +../lib/obstack.h and ../config.h. + +Each module *must* define the symbol "m4_macro_table" as a pointer to a +table of "struct builtin" (defined in m4.h). The table ends with an +entry with name == NULL. The builtins described in the table will be +defined by GNU m4 as were they normal builtins. + +If a module defines the symbol "m4_init_module", it is supposed to be a +function with a prototype of "void m4_init_module(struct obstack *obs)", +and it will be called as soon as the module is loaded. Any non-finished +object left on the obstack will be the expansion of the call of the +builtin "loadmodule". The obstack pointer might be NULL (in the future). + +If a module defines the symbol "m4_finish_module", it is supposed to be +a function with a prototype of "void m4_finish_module(void)", and it +will be called just before GNU m4 exits. This will allow a module to +clean up before exit. There is no way of communicating information to +the user, as GNU m4 exits immeidately afterwards. + +No other symbols will be used by GNU m4. Other external symbols within +the module are private and will not be accessible to GNU m4 or to other +modules. + +Modules are allowed to call external functions already defined within +the GNU m4 sources. Some of these have prototypes in builtin.h. + + +A complete, though silly, example is found in test.c.

The code for HPUX shl_load() still needs testing and debugging. + A dld interface is also missing. Any volunteers? + +* The files from the GNU m4 web-site is now in examples/WWW as a more + complete example of what GNU m4 can do. + +Version beta 1.4l - November 1998, by Rene' Seindal + +* GNU m4 now has an escape syntax category. If a character is marked as + an escape, words are only recognised as macros if preceded by an escape + character. It is a bit like -P, but dynamic: it can be turned on and + off. The GNU m4 web-site on http://www.seindal.dk/rene/gnu/ is + maintained with this feature - the m4 source is available on the site. + +* The module interface is improved, thanks to "Brian J. Fox" + <bfox@datawave.net>, who have contributed some code from Meta-HTML. The + modules now build automatically and installs properly, by default in + /usr/local/libexec/m4. There is a preliminary, untested support for + shl_load(). + +* There is now a __m4_version__ macro that expands to the current version + number. + +Version beta 1.4k - November 1998, by Erick Branderhorst and Rene' Seindal + +* GNU m4 now uses gettext to support internationalization. + +* GNU m4 now uses automake to control Makefile.in generation. This + should make it more consistent with the GNU standards. + +* GNU m4 will use the gmp library for multiple precision integral and + rational arithmetic in `eval' if configured with `--with-gmp'. If + configured without `--with-gmp' or if gmp is not available, and the type + `long long int' is, GNU m4 will use that for `eval' arithmetic. + +* GNU m4 now parses the input according to a syntax table, that can be + modified through the new builtin `changesyntax'. It is a generalisation + of the existing builtins `changecom' and `changequote'. The changes are + completely backwards compatible (except for the existence of + `changesyntax'). + +* Sync lines can be turned on and off with the `syncoutput' builtin. The + builtin `syncoutput' is a GNU extension. + +* New experimental feature: dynamically loadable modules. New builtin + `loadmodules' loads shared libraries, that can define new builtin + macros, ie, new macros can be written in C. Depends on the dlopen() + interface, and is currently only tested on Linux. Enabled at configure + time with `--with-modules'. Documentation is in src/module.c and + module/README. + +* Implement a GNU message catalog for French (Franc,ois Pinard). + +* Filenames found through path searches are now correctly reflected in + error and debug messages and through the `__file__' macro. + +Bugs fixed + +* All 8-bit characters can now be used for quotes. + + +Version 1.4 - October 1994, by Franc,ois Pinard + +(No user visible changes) + + +Version 1.3 - September 1994, by Franc,ois Pinard + +* Diversions are created as needed. Option `-N' is still accepted, but +otherwise ignored. Users should use only negative diversion numbers, +instead of high positive numbers, for diverting to nowhere. + +* Diversions should also work faster. No temporary files will be needed +at all if all diversions taken altogether do not use more than 512K. + +* Frozen state files may be produced with the `--freeze-state' (-F) +option and later brought back through the `--reload-state' (-R) option. + + +Version 1.2 - July 1994, by Franc,ois Pinard + +* In patsubst(STRING, REGEXP, REPLACEMENT), \& in REPLACEMENT has been +changed to represent this part of STRING matched by the whole REGEXP, +instead of the whole STRING as before. \0 does the same, but emits a +diagnostic saying it will disappear in some subsequent release. + +* eval(EXPR) emits a diagnostic if EXPR has suffixed crumb. The same for +other numeric conversions in incr(), decr(), divert(), etc. + +* `--fatal-warnings' (-E) stops execution at first warning. + +* `--nesting-limit=LEVEL' (-L LEVEL) sets a limit to macro nesting. +It is initially fixed at 250. + +* `--word-regexp=REGEXP' (-W REGEXP) modifies macro name syntax, like +does the new `changeword(REGEXP)' macro. This feature is experimental, +tell me your opinions about it. You do need --enable-changeword at +configure time to get these things. Do *not* depend on them yet. + +* Trace output format is scannable by GNU Emacs' next-error function. + +* Stack overflow is detected and diagnosed on some capable systems. + +* Various bugs have been corrected, m4 should be more portable. See the +ChangeLog for details. + + +Version 1.1 - November 1993, by Franc,ois Pinard + +Changes which might affect existing GNU m4 scripts: + +* Option `-V' has been removed, use `--version' instead. `--version' +writes on standard output instead of standard error, and inhibits any +script execution. + +* `--no-gnu-extensions' has been renamed `--traditional'. + +* In `eval', `^' used to indicate exponentiation, use `**' instead. + +* The automatic undiversion which takes place at end of all input is +forced into the main output stream. + +Changes which are unlikely to affect existing scripts: + +* `--help' prints an usage summary on standard output. Script execution +is then inhibited. + +* `--prefix-builtins' (-P) prefixes all builtin macros by `m4_'. + +* Most builtin macros for which arguments are mandatory, called without +any arguments, are no more recognized as builtin macros: they are +consequently copied verbatim to the output stream. + +* `define' and `pushdef' are usable with only one argument, they give +this argument an empty definition. + +* `eval' new operators for binary representation handling: `^' for +exclusive-or, `~' for the bitwise negation, `<<' and `>>' for shifts. + +* `eval' recognizes the notation 0bDIGITS for binary numbers and the +notation 0rRADIX:DIGITS for numbers in any radix from 1 to 36. + +Version 1.0.3 - December 1992, by Franc,ois Pinard + +Changes for the user: + +* `dnl' outputs a diagnostic if immediately followed by `('. Usually, +`dnl' is followed by newline or whitespace. + +* `ifelse' accepts without complaining the common idiom of having only +one argument. This is useful for introducing long comments. + +* `eval' always expresses values as signed, whatever the radix. + +* M4OPTS environment variable is no longer obeyed. + +* `--no-warnings' option is renamed `--silent'. + +* Debug lines use a new format more compatible with GNU standards. + +* Various bugs have been corrected. See the ChangeLog for details. + +Changes for the installer: + +* GNU m4 now uses an Autoconf-generated configure script, and should be +more easily portable in many ways. (Cray is not supported yet). + +* `make check' has been made more portable, expect no errors. + +Changes for the programmer: + +* Sources have been fully reindented to comply with GNU standards, and +cleaned up in many ways. + +* Sources have been protoized. Non-ANSI compilers are automatically +detected, then sources are unprotoized on the fly before compilation. + +* GNU m4 uses newer versions of obstack, regex, getopt, etc. + +Version 1.0 - October 1991, by Rene' Seindal + +* Uses GNU configure, taken from the gdb distribution. + +* Uses GNU getopt(), with long option names. + +* The -Q/+quiet option is added, which suppresses warnings about missing +or superflous arguments to built-in macros. + +* Added default options via the M4OPTS environment variable. + +* Several minor bugs have been fixed. + +Version 0.99 - July 1991, by Rene' Seindal + +* The builtins `incr' and `decr' are now implemented without use of +`eval'. + +* The builtin `indir' is added, to allow for indirect macro calls +(allows use of "illegal" macro names). + +* The debugging and tracing facilities has been enhanced considerably. +See the manual for details. + +* The -tMACRO option is added, marks MACRO for tracing as soon as it +is defined. + +* Builtins are traced after renaming iff they were before. + +* Named files can now be undiverted. + +* The -Nnum option can be used to increase the number of divertions +available. + +* Calling changecom without arguments now disables all comment handling. + +* A bug in `dnl' is fixed. + +* A bug in the multi-character quoting code is fixed. + +* Several typos in the manual has been corrected. More probably persist. + +Version 0.75 - November 1990, by Rene' Seindal + +* Implemented search path for include files (-I option and M4PATH +environment variable). + +* Implemented builtin `format' for printf-like formatting. + +* Implemented builtin `regexp' for searching for regular expressions. + +* Implemented builtin `patsubst' for substitution with regular +expressions. + +* Implemented builtin `esyscmd', which expands to a shell commands output. + +* Implemented `__file__' and `__line__' for use in error messages. + +* Implemented character ranges in `translit'. + +* Implemented control over debugging output. + +* Implemented multi-character quotes. + +* Implemented multi-character comment delimiters. + +* Changed predefined macro `gnu' to `__gnu__'. + +* Changed predefined macro `unix' to `__unix__', when the -G option is +not used.

If +you intend to use m4 seriously, you might find useful material down +there. + +See file `COPYING' for copying conditions. +See file `INSTALL' for compilation and installation instructions. +See file `ABOUT-NLS' for how to customize this program to your language. +See file `NEWS' for a list of major changes in the current release. +See file `THANKS' for a list of contributors. + +By using `./configure --with-gmp, you get multiple precision integral +and rational arithmetic in eval. The implementation depends on the GNU +gmp v2 library. + +By using `./configure --with-modules, you get the possibility of using +dynamic modules. The implementation depends on dlopen(3) interface. +See file `modules/README' for a more detailed description. + +By using `./configure --enable-changeword', you get an experimental +feature which allows for changing the syntax of what is a "word" in +`m4'. THIS WILL PROBABLY GO AWAY, so don't count on it. Some of the +same things can be achieved with `changesyntax' at a much better speed. + +By using `./configure --with-dmalloc', GNU m4 is linked with Gray +Watson's dmalloc package. It is a debugging option for finding memory +management problems. Gray Watson's dmalloc package is available at +ftp://ftp.letters.com/src/dmalloc/dmalloc.tar.gz. + +Send bug reports, comments or ideas to `bug-m4@gnu.org'. A bug report +is an adequate description of the problem: your input, what you +expected, what you got, and why this is wrong. Diffs are welcome, but +they only describe a solution, from which the problem might be uneasy to +infer.

Macros are either +builtin or user-defined, and can take any number of arguments. Besides +just doing macro expansion, m4 has builtin functions for including named +files, running UNIX commands, doing integer arithmetic, manipulating +text in various ways, recursion, etc... m4 can be used either as a +front-end to a compiler, or as a macro processor in its own right. +</P> + + +<P> +The m4 macro processor is widely available on all UNIXes. Usually, +only a small percentage of users are aware of its existence. However, +those who do often become commited users. The growing popularity of GNU +Autoconf, which prerequires GNU m4 for generating the `configure' +scripts, is an incentive for many to install it, while these people will +not themselves program in m4. GNU m4 is mostly compatible with the +System V, Release 3 version, except for some minor differences. +</P> + + +<P> +Some people found m4 to be fairly addictive. They first use m4 for +simple problems, then take bigger and bigger challenges, learning how to +write complex m4 sets of macros along the way. Once really addicted, +users pursue writing of sophisticated m4 applications even to solve +simple problems, devoting more time debugging their m4 scripts than +doing real work. Beware that m4 may be dangerous for the health of +compulsive programmers. +</P> + + +<P> +Autoconf needs GNU m4 for generating `configure' scripts, but not for +running them. +</P> + + + +</TD> + +</TR> + +</TABLE> + +</BODY> + + +</HTML> + + diff --git a/examples/capitalize.m4 b/examples/capitalize.m4 new file mode 100644 index 00000000..5c28de22 --- /dev/null +++ b/examples/capitalize.m4 @@ -0,0 +1,8 @@ +dnl +dnl convert to upper- resp. lowercase +define(`upcase', `translit(`$*', `a-z', `A-Z')') +define(`downcase', `translit(`$*', `A-Z', `a-z')') +dnl +dnl capitalize a single word +define(`capitalize1', `regexp(`$1', `^\(\w\)\(\w*\)', `upcase(`\1')`'downcase(`\2')')') +define(`capitalize', `patsubst(`$1', `\w+', ``'capitalize1(`\0')')') diff --git a/examples/capitalize.test b/examples/capitalize.test new file mode 100755 index 00000000..5b80f5c0 --- /dev/null +++ b/examples/capitalize.test @@ -0,0 +1,21 @@ +#!/bin/sh + +# capitalize.test is part of the GNU m4 testsuite + +. ${srcdir}/defs + +cat ${srcdir}/capitalize.m4 >in + +cat <<\EOF >ok + + +CONVERT TO UPPER CASE +convert to lower case + + +This Sentence Should Be Capitalized +EOF + +M4PATH=$srcdir:$srcdir/../tests $M4 -d in >out 2>err +sed -e "s, ../../src/m4:, m4:," err >sederr && mv sederr err +$CMP -s out ok diff --git a/examples/comments.m4 b/examples/comments.m4 new file mode 100644 index 00000000..c1e3be0a --- /dev/null +++ b/examples/comments.m4 @@ -0,0 +1,7 @@ +# An ordinary comment +define(`foo', # A comment in a macro +`Macro `foo' expansion') +foo +define(`comment', `*** Macro `comment' expansion ***') +changecom(`@', `@') +foo diff --git a/examples/comments.test b/examples/comments.test new file mode 100755 index 00000000..63161dc2 --- /dev/null +++ b/examples/comments.test @@ -0,0 +1,24 @@ +#!/bin/sh + +# comments.test is part of the GNU m4 testsuite + +. ${srcdir}/defs + +cat <<\EOF >in +include(comments.m4)dnl +EOF + +cat <<\EOF >ok +# An ordinary comment + +# A comment in a macro +Macro foo expansion + + +# A *** Macro comment expansion *** in a macro +Macro foo expansion +EOF + +M4PATH=$srcdir $M4 -d in >out + +$CMP -s out ok diff --git a/examples/ddivert.m4 b/examples/ddivert.m4 new file mode 100644 index 00000000..e6e0017e --- /dev/null +++ b/examples/ddivert.m4 @@ -0,0 +1,4 @@ +divert(1)Text diverted a first time. +divert(0)undivert(1)dnl +divert(1)Text diverted a second time. +divert(0)undivert(1)dnl diff --git a/examples/ddivert.test b/examples/ddivert.test new file mode 100755 index 00000000..5db82e90 --- /dev/null +++ b/examples/ddivert.test @@ -0,0 +1,18 @@ +#!/bin/sh + +# ddivert.test is part of the GNU m4 testsuite + +. ${srcdir}/defs + +cat <<\EOF >in +include(ddivert.m4)dnl +EOF + +cat <<\EOF >ok +Text diverted a first time. +Text diverted a second time. +EOF + +M4PATH=$srcdir $M4 -d in >out + +$CMP -s out ok diff --git a/examples/debug.m4 b/examples/debug.m4 new file mode 100644 index 00000000..16f4c74e --- /dev/null +++ b/examples/debug.m4 @@ -0,0 +1,4 @@ +define(`countdown', `$1 ifelse(eval($1 > 0), 1, `countdown(decr($1))', `Liftoff')') +debugmode(`aeqc') +traceon(`countdown') +countdown(2) diff --git a/examples/debug.test b/examples/debug.test new file mode 100755 index 00000000..0260641e --- /dev/null +++ b/examples/debug.test @@ -0,0 +1,33 @@ +#!/bin/sh + +# debug.test is part of the GNU m4 testsuite + +. ${srcdir}/defs + +cat <<\EOF >in +include(debug.m4)dnl +EOF + +cat <<\EOF >ok + + + +2 1 0 Liftoff +EOF + +cat <<\EOF >okerr +m4trace: -1- countdown ... +m4trace: -1- countdown(`2') -> ??? +m4trace: -1- countdown(...) -> `2 ifelse(eval(2 > 0), 1, `countdown(decr(2))', `Liftoff')' +m4trace: -1- countdown ... +m4trace: -1- countdown(`1') -> ??? +m4trace: -1- countdown(...) -> `1 ifelse(eval(1 > 0), 1, `countdown(decr(1))', `Liftoff')' +m4trace: -1- countdown ... +m4trace: -1- countdown(`0') -> ??? +m4trace: -1- countdown(...) -> `0 ifelse(eval(0 > 0), 1, `countdown(decr(0))', `Liftoff')' +EOF + +M4PATH=$srcdir $M4 -d in >out 2>err +sed -e "s, ../../src/m4:, m4:," err >sederr && mv sederr err + +$CMP -s out ok && $CMP -s err okerr diff --git a/examples/defs b/examples/defs new file mode 100644 index 00000000..cf97e3b3 --- /dev/null +++ b/examples/defs @@ -0,0 +1,54 @@ +# -*- ksh -*- +# Defines for GNU m4 testing environment. +# Erick Branderhorst <Erick.Branderhorst@asml.nl> + +# Ensure $srcdir set correctly. +test -f ${srcdir}/defs || { + echo "defs: installation error" 1>&2 + exit 1 +} + +# If srcdir is relative, we need to modify it. +case "$srcdir" in + /*) + ;; + + *) + srcdir="../$srcdir" + ;; +esac + +rm -rf testSubDir > /dev/null 2>&1 +mkdir testSubDir +cd testSubDir + +# Build appropriate environment in test directory.
