1 Contributing to GNU Stow
2 ========================
4 Development of Stow, and GNU in general, is a volunteer effort, and
5 you can contribute. If you'd like to get involved, it's a good idea to join
6 the [stow-devel](https://lists.gnu.org/mailman/listinfo/stow-devel)
12 Please follow the procedure described in [the "Reporting Bugs"
13 section](https://www.gnu.org/software/stow/manual/html_node/Reporting-Bugs.html#Reporting-Bugs)
14 of [the manual](README.md#documentation).
19 For [development sources](https://savannah.gnu.org/git/?group=stow)
20 and other information, please see the [Stow project
21 page](http://savannah.gnu.org/projects/stow/) at

28 Please be aware that all program source files (excluding the test
29 suite) end in `.in`, and are pre-processed by `Makefile` into
30 corresponding files with that prefix stripped before execution. So if
31 you want to test any modifications to the source, make sure that you
32 change the `.in` files and then run `make` to regenerate the
33 pre-processed versions before doing any testing. To avoid forgetting
34 (which can potentially waste a lot of time debugging the wrong code),
35 you can automatically run `make` in an infinite loop every second via:
39 (You could even use fancier approaches like
40 [`inotifywait(1)`](https://www.man7.org/linux/man-pages/man1/inotifywait.1.html)
41 or [Guard](https://guardgem.org/). But those are probably overkill in
42 this case where the simple `while` loop is plenty good enough.)
47 The test suite can be found in the [`t/`](t/) subdirectory. You can
48 run the test suite via:
52 Tests can be run individually as follows. First you have to ensure
53 that the `t/`, `bin/`, and `lib/` directories are on Perl's search path.
54 Assuming that you run all tests from the root of the repository tree,
57 export PERL5LIB=t:bin:lib
59 (Not all tests require all of these, but it's safer to include all of
62 Secondly, be aware that if you want to test modifications to the
63 source files, you will need to run `make watch`, or `make` before each
64 test run as explained above.
66 Now running an individual test is as simple as:
70 or with a given debugging verbosity corresponding to the `-v` / `--verbose`
73 TEST_VERBOSE=4 perl t/chkstow.t
75 The [`prove(1)` test runner](https://perldoc.perl.org/prove) is another
76 good alternative which provides several handy extra features. Invocation
77 is very similar, e.g.:
81 or to run the whole suite:
85 However currently there is an issue where this interferes with
88 If you want to create test files for experimentation, it is
89 recommended to put them in a subdirectory called `playground/` since
90 this will be automatically ignored by git and the build process,
91 avoiding any undesirable complications.
96 To view test coverage reports, first ensure that
97 [`Devel::Cover`](https://metacpan.org/dist/Devel-Cover) is installed.
98 Then type `make coverage`. The last lines of the output should
99 include something like:
101 HTML output written to /home/user/path/to/stow/cover_db/coverage.html
103 which you can open in a web browser to view the report.
108 Stow is not currently multi-lingual, but patches would be very
109 gratefully accepted. Please e-mail
110 [stow-devel](https://lists.gnu.org/mailman/listinfo/stow-devel) if you
111 intend to work on this.
116 Stow is currently being maintained by Adam Spiers. Please use [the
117 mailing lists](README.md#mailing-lists).
