shtool-version - Man Page

shtool version [-l|--language lang] [-n|--name name] [-p|--prefix prefix] [-s|--set version] [-e|--edit] [-i|--increase knob] [-d|--display type] file

This command displays and maintains version information in file.

The version is always described with a triple <version,revision,level> and is represented by a string which always matches the regular expression "[0-9]+\.[0-9]+[sabp.][0-9]+".

The hexadecimal format for a version v.rtl is VVRRTLL where VV and RR directly correspond to v and r, T encodes the level type as 9, 2, 1, 0 (representing s, p/., b, a in this order) and LL is either directly corresponding to l or set to 99 if level type is s.

The following command line options are available.

-v,  --verbose

Print verbose information during processing.

-l,  --language lang

Choose format of version file file. lang="txt", ANSI C (lang="c"), M4 (lang="m4"), Perl (lang="perl") or Python (lang="python"). Default is txt.

-n,  --name name

Name the program the version is maintained for. Default is unknown.

-p,  --prefix prefix =item -s,  --set version

Set the version to version.

-e,  --edit

Interactively enter a new version.

-i,  --increase knob

When option “-i” is used, the current version in file is updated by increasing one element of the version where knob can be one of the following: “v” for increasing the version by 1 (and resetting revision and level to 0), “r” for increasing the revision by 1 (and resetting level to 0) or “l” for increasing the level by 1.

-d,  --display type

Control the display type: "short" for a short version display, "long" for a longer version display, "hex" for a hexadecimal display of the version and "libtool" for a format suitable for use with GNU libtool.

 #   shell script
 shtool version -l c -n FooBar -p foobar -s 1.2b3 version.c

 #   configure.in
 V=`shtool version -l c -d long version.c`
 echo "Configuring FooBar, Version $V"

The GNU shtool version command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1994 for OSSP eperl. It was later rewritten from scratch for inclusion into GNU shtool.
