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