2## This target generates an include file that contains the git version
3## string of the current branch, it must be continuously updated when
4## we build in the git repo and shipped in dist tarballs to reflect the
5## status of the tree when it was generated. If the tree is clean and
6## the current commit is tag a starting with "v", consider this a
7## release version and set an empty git version.
8##
9## Here is what the inline script does:
10##
11## First, delete any stale "version.i.tmp" file.
12##
13## If "bootstrap" and ".git" exists in the top source directory and the git
14## executable is available, get the current git version string in the form:
15##
16## "latest_tag"(-"number_of_commits_on_top")(-g"latest_commit_hash")(-dirty)
17##
18## And store it in "version.i.tmp", if the current commit is tagged, the tag
19## starts with "v" and the tree is clean, consider this a release version and
20## overwrite the git version with an empty string in "version.i.tmp".
21##
22## If we don't have a "version.i.tmp" nor a "version.i", generate an empty
23## string as a failover. If a "version.i" is present, for example when building
24## from a distribution tarball, get the git_version using grep.
25##
26## Fetch the EXTRA_VERSION_NAME define from "version/extra_version_name" and output it
27## to "version.i.tmp".
28##
29## Fetch the EXTRA_VERSION_DESCRIPTION define from "version/extra_version_description",
30## sanitize and format it with a sed script to replace all non-alpha-numeric values
31## with "-" and join all lines by replacing "\n" with litteral string c-style "\n\t" and
32## output it to "version.i.tmp".
33##
34## Repeat the same logic for the "version/extra_patches" directory.
35## Data fetched from "version/extra_patches" must be sanitized and
36## formatted.
37## The data is fetched using "ls" with an ignore pattern for the README file.
38## The sanitize step uses sed with a script to replace all
39## non-alpha-numeric values, except " " (space), to "-".
40## The formatting step uses sed with a script to join all lines
41## by replacing "\n" with litteral string c-style "\n\t".
42##
43## If we don't have a "version.i" or we have both files (version.i, version.i.tmp)
44## and they are different, copy "version.i.tmp" over "version.i".
45## This way the dependent targets are only rebuilt when the git version
46## string or either one of extra version string change.
