Older versions of git, when cloning a repo and
the expected source templates directory does not
exist, does not create .git/hooks, which causes
nhgitset.pl to fail. So do it here.
Update dat/gitinfo.txt if the current branch is different from the
one recorded in the file, not just when the commit hash is different.
Make the usual output less verbose so that it fits within 80 columns.
installing the hooks first
NHgithook.pm: add some warnings if nhversioning can't open files
make sure nhversioning fails before opening gitinfo.txt if it can't get valid
data
Incorporate some git information into NetHack so that it
is potentially visible to a player. That's useful when
collecting details about the version that they are
running and, if the gitinfo is present, it can tie the
code to a specific git commit in the repository.
This modifies 'makedefs -v' to check for the presence of a data file
called dat/gitinfo.txt and if it is there, parse out its
contents, then write additional lines to include/date.h beyond
what 'makedefs -v' was previously putting in there, similar to
this sample:
#define NETHACK_GIT_SHA "0c84e564c78e2024e562d39539376ce2e21eec8e"
#define NETHACK_GIT_BRANCH "NetHack-3.6.0"
The contents of an appropriate dat/gitinfo.txt are as follows,
and trailing/leading whitespace is not significant:
githash = 0c84e564c78e2024e562d39539376ce2e21eec8e
gitbranch = NetHack-3.6.0
It also adjusts the contents of the 'v' version information to
include the additional git info when available.
Also adds some hooks DEVEL/hooksdir and a perl file to DEVEL
for simplifying and automating the deposit of dat/gitinfo.txt
so that it generally reflects the most current git commit.
DEVEL/gitinfo.pl can be used to build dat/gitinfo.txt at any
time without doing a commit, merge, or checkout.
perl DEVEL/gitinfo.pl
command line --version and -version support
To complement the extra information being provided in the
version by the 'v' command, this also adds support for the
following new command line arguments:
--version
-version Output the NetHack version string then exit.
--version:paste Output the NetHack version string and also copy it to
-version:paste the platform's paste buffer for insertion somewhere,
then exit.
If the paste variation of -version is requested on a platform that
hasn't incorporated any support for the capability, it will deliver
the version info then an error message, prior to exiting.
To support the extended -version:paste variation, a port needs to:
- provide a port-specific routine to perform
the paste buffer copy in a port code file.
- #define RUNTIME_PASTEBUF_SUPPORT in the include/portconf.h header file.
--skeleton--
void port_insert_pastebuf(buf)
char *buf;
{
/* insert code to copy the version info from buf into
platform's paste buffer in a supported way */
}
macosx and Windows have both added support for RUNTIME_PASTEBUF_SUPPORT
- fix bug in git hooks that loses file permissions when doing variable expansion
- fix execute permissions on sys/unix/hints/macosx.sh
- explicitly call out perl as required for hooks in Developer.txt
I've put my best approximation of what the style should be in here. I
don't intend for this to be prescriptive, except as the DevTeam has
agreed, so I do encourage discussion on the mailing list. I would also
appreciate if people with other editors could include the appropriate
configuration recipes.
