Greetings all. This note announces the next major release of GNU Awk: version 4.1.0.
The following files may be retrieved from ftp://ftp.gnu.org/gnu/gawk, or via HTTP from http://ftp.gnu.org/gnu/gawk: -rw-r--r-- 1 3003 3002 490 May 10 09:50 gawk-4.1.0.tar.xz.sig -rw-r--r-- 1 3003 3002 2049080 May 10 09:50 gawk-4.1.0.tar.xz -rw-r--r-- 1 3003 3002 490 May 10 09:49 gawk-4.1.0.tar.gz.sig -rw-r--r-- 1 3003 3002 3995528 May 10 09:49 gawk-4.1.0.tar.gz This is a major new release, with a number of new features. The relevant part of the NEWS file is appended below. This release represents close to two years of very hard work by a number of people. I thank them all for their contributions, I could not have done it by myself. Differences from gawk 4.0.2 are not available; they would be too large. The usual GNU build incantation should be used: tar -xpvzf gawk-4.1.0.tar.gz cd gawk-4.1.0 ./configure && make && make check Bug reports should be sent to bug-g...@gnu.org. Enjoy! Arnold Robbins (on behalf of all the gawk developers) arn...@skeeve.com ------------------------------------------------------------ Changes from 4.0.2 to 4.1.0 --------------------------- 1. The three executables gawk, pgawk, and dgawk, have been merged into one, named just gawk. As a result: * The -R option is gone * Use -D to run the debugger. An optional file argument is a list of commands to run first. * Use -o to do pretty-printing only. * Use -p to do profiling. This considerably reduces gawk's "footprint" and eases the documentation burden as well. 2. Gawk now supports high precision arithmetic with MPFR. The default is still double precision, but setting PREC changes things, or using the -M / --bignum options. This support is not compiled in if the MPFR library is not available. 3. The new -i option (from xgawk) is used for loading awk library files. This differs from -f in that the first non-option argument is treated as a script. 4. The new -l option (from xgawk) is used for loading dynamic extensions. 5. The dynamic extension interface has been completely redone! There is now a defined API for C extensions to use. A C extension acts like a function written in awk, except that it cannot do everything that awk code can. However, this allows interfacing to any facility that is available from C. This is a major development, see the doc, which has a nice shiny new chapter describing everything. This support is not compiled in if dynamic loading of shared libraries is not supported. The old extension mechanism is still supported for compatiblity, but it will most definitely be removed at the next major release. 6. The "inplace" extension, built using the new facility, can be used to simulate the GNU "sed -i" feature. 7. The and(), or() and xor() functions now take any number of arguments, with a minimum of two. 8. New arrays: SYMTAB, FUNCTAB, and PROCINFO["identifiers"]. SYMTAB allows indirect access to any defined variable or array; it is possible to "walk" the symbol table, if that should be necessary. 9. Support for building gawk with a cross compiler has been improved. 10. Infrastructure upgrades: bison 2.7.1, gettext 0.18.2.1, automake 1.13.1, libtool 2.4.2 for the extensions. _______________________________________________ GNU Announcement mailing list <info-gnu@gnu.org> https://lists.gnu.org/mailman/listinfo/info-gnu
