mingw-pkg

Fork

Optimize program configuration procedure.

* src/modules/config.sh (/etc/mingw-pkg/*.sh): New configuration
script source; process matching scripts before, but together with...
($HOME/.mingw-pkgrc, .mingw-pkg/*.sh): ...these, as previously, but
now incorporating all within the scope of a single "for" loop.

Identify mkspec target directory more intelligently.

* src/modules/mkspec.sh (SPECSFILE_DIR): Assign it as...
[SRCDIR defined] (SRCDIR): ...this; otherwise assign it as...
[! SRCDIR defined] (PACKAGE_SRCDIR): ...this.

Add mkspec "--edit" and "--force-overwrite" options.

* src/modules/options.sh (--edit, --force-overwrite): Define them.
* src/modules/mkspec.sh (--edit, --force-overwrite): Implement them.
* src/modules/help.sh (--edit, --force-overwrite): Document them.

Avoid accidental overwrite of pkgspec files.

* src/modules/options.sh (OUTPUT_STREAMING_OPTION): Rename as...
(write_stdout): ...this; set value to "true", when applicable.

* src/modules/mkspec.sh (write_stdout): Evaluate it.
(SPECSFILE_DIR, SPECSFILE): Identify pkgspec file as a composite of
this pair of shell variables; do NOT include any contribution from...
(RELEASE): ...this additional variable, even if it is assigned.
[! write_stdout]: Test for prior existence of pkgspec file;
abort when already present.

Encapsulate component package examples within comments.

* src/modules/mkspec.sh (component ...): Mark all as comments.
(subpackage): Add example, encapsulating the DLL component.

Honour "--identity" option for specification file name.

* src/modules/pkgspec.sh (pkgspec_from_srcdir): Prioritize over...
[-n PACKAGE_ABS_SRCDIR] (PACKAGE_ABS_SRCDIR): ...this, preferred to...
[-z PACKAGE_ABS_SRCDIR] (PACKAGE_SRCDIR): ...this; do NOT use this by
default, because it doesn't yield a valid specification file name, in
the common case where its basename is "..", or ".".

Avoid duplication of diagnostic message functions.

* src/modules/config.sh (bold, unbold, error_colour, warning_colour)
(warning, error): Delete definitions; import them by requiring...
* src/modules/dmh.sh: ...this instead.

Don't track autoconf backup files in SCM.

* .hgignore (**~): Add glob pattern.

Verify accessibility of git and hg root directories.

* src/plugins/git.sh src/plugins/hg.sh (initialize_abs_srcdir): Use it
to verify that the nominated package source directory actually exists;
abort if it doesn't, when it is required to do so.

Improve source directory identification mechanisms.

* src/modules/pkgspec.sh (initialize_abs_srcdir, abs_srcdir): New
functions; implement them to identify, and report source path name.
(pkgspec_from_srcdir): Do not require the basename from...
(PACKAGE_ABS_SRCDIR): ...this; it may not be defined, whereas...
(PACKAGE_SRCDIR): ...this is, and is sufficient.

* Makefile.in (clean, mostlyclean, distclean, realclean)

Ensure version changes are propagated to scripts.
