changes to get it to build on NetBSD are extensive - for reference,
and the one who comes after me, they are:
+ awk.h defines "proc" in a cpp macro. This doesn't sit too well with
"struct proc" references, as found in <sys/uio.h>. The good news is that
only awk.h and awkgram.y need to be modified to workaround this.
+ the present Makefile copying wrt gettext Makefile.in.in is unnecessary
+ automake is a pre-req of this package
+ and there is a problem in Makefile.in/configure with ${AUTOMAKE} not
being defined properly
and many, many more...
Enable this package for all platforms.
Added GAWK_ENABLE_PORTALS to mk/bsd.pkg.defaults.mk to enable/disable gawk
handling file names that start with `/p/' as a 4.4 BSD type portal file.
Changes from 3.0.4 to 3.0.5:
- bug fix release only.
Changes from 3.0.5 to 3.0.6:
- bug fix release only.
Changes from 3.0.6 to 3.1.0:
- A new PROCINFO array provides info about the process. The non-I/O /dev/xxx
files are now obsolete, and their use always generates a warning.
- A new `mktime' builtin function was added for creating time stamps. The
`mktime' function written in awk was removed from the user's guide.
- New `--gen-po' option creates GNU gettext .po files for strings marked
with a leading underscore.
- Gawk now completely interprets special file names internally, ignoring the
existence of real /dev/stdin, /dev/stdout files, etc.
- The mmap code was removed. It was a worthwhile experiment that just
didn't work out.
- The BINMODE variable is new; on non-UNIX systems it affects how gawk
opens files for text vs. binary.
- Gawk no longer supports `next file' as two words.
- On systems that support it, gawk now sets the `close on exec' flag on all
files and pipes it opens. This makes sure that child processes run via
system() or pipes have plenty of file descriptors available.
- If `--posix' is in effect, newlines are not allowed after ?:.
- Weird OFMT/CONVFMT formats no longer cause fatal errors.
- Diagnostics about array parameters now include the parameter's name,
not just its number.
- It is now possible to open a two-way pipe via the `|&' operator.
See the discussion in the manual about putting `sort' into such a pipeline,
though. (NOTE! This is borrowed from ksh: it is not the same as
the same operator in csh!)
- The close() function now takes an optional second string argument
that allows closing one or the other end of the two-way pipe to
a co-process. This is needed to use `sort' in a co-process, see
the doc.
- If TCP/IP is available, special file names beginning with `/inet'
can be used with `|&' for IPC.
- With `--enable-portals' on the configure command line, gawk will also
treat file names that start with `/p/' as a 4.4 BSD type portal file,
i.e., a two-way pipe for `|&'.
- Unrecognized escapes, such as "\q" now always generate a warning.
- The LINT variable is new; it provides dynamic control over the --lint
option.
- Lint warnings can be made fatal by using --lint=fatal or `LINT = "fatal"'.
Use this if you're really serious about portable code.
- A number of lint warnings have been added. Most notably, gawk will
detect if a variable is used before assigned to. Warnings for
when a string that isn't a number gets converted to a number are
in the code but disabled; they seem to be too picky in practice.
Also, gawk will now warn about function parameter names that shadow
global variable names.
- It is now possible to dynamically add builtin functions on systems
that support dlopen. This facility is not (yet) as portable or well
integrated as it might be. *** WARNING *** THIS FEATURE WILL EVOLVE!
- Profiling has been added! A separate version of gawk, named pgawk, is
built and generates a run-time execution profile. The --profile option
can be used to change the default output file. In regular gawk, this
option pretty-prints the parse tree.
- Gawk has been internationalized, using GNU gettext. Translations for
future distributions are most welcome.
- New asort() function for sorting arrays. See the doc for details.
- The match function takes an optional array third argument to hold
the text matched by parenthesized sub-expressions.
- The bit op functions and octal and hex source code constants are on by
default, no longer a configure-time option. Recognition of non-decimal
data is now enabled at runtime with --non-decimal-data command line option.
- Internationalization features available at the awk level: new TEXTDOMAIN
variable and bindtextdomain() and dcgettext() functions. printf formats
may contain the "%2$3.5d" kind of notation for use in translations. See
the texinfo manual for details.
- The return value from close() has been rationalized. Most notably,
closing something that wasn't open returns -1 but remains non-fatal.
- The array effeciency change from 3.0.5 was reverted; the semantics were
not right. Additionally, index values of previously stored elements
can no longer change dynamically.
- The new option --dump-variables dumps a list of all global variables and
their final types and values to a file you give, or to `awkvars.out'.
- Gawk now uses a recent version of random.c courtesy of the FreeBSD
project.
- The gawk source code now uses ANSI C function definitions (new style),
with ansi2knr to translate code for old compilers.
- `for (iggy in foo)' loops should be more robust now in the face of
adding/deleting elements in the middle; they loop over just the elements
that are present in the array when the loop starts.
Summary of changes:
- removal of USE_GTEXINFO
- addition of mk/texinfo.mk
- inclusion of this file in package Makefiles requiring it
- `install-info' substituted by `${INSTALL_INFO}' in PLISTs
- tuning of mk/bsd.pkg.mk:
removal of USE_GTEXINFO
INSTALL_INFO added to PLIST_SUBST
`${INSTALL_INFO}' replace `install-info' in target rules
print-PLIST target now generate `${INSTALL_INFO}' instead of `install-info'
- a couple of new patch files added for a handful of packages
- setting of the TEXINFO_OVERRIDE "switch" in packages Makefiles requiring it
- devel/cssc marked requiring texinfo 4.0
- a couple of packages Makefiles were tuned with respect of INFO_FILES and
makeinfo command usage
