3 PATCHES - track and distribute your code changes
7 This page documents how to distribute your changes to GNU LilyPond
11 Distributing a change normally goes like this:
17 make your fix/add your code
21 Add changes to NEWS, and add yourself to Documentation/AUTHORS.pod
29 e-mail your patch to one of the mailing lists
30 gnu-music-discuss@gnu.org or bug-gnu-music@gnu.org
35 =head1 GENERATING A PATCH
37 In F<VERSION>, set TOPLEVEL_MY_PATCH_LEVEL:
41 TOPLEVEL_MY_PATCH_LEVEL = jcn1
43 In F<NEWS>, enter a summary of changes:
49 Then, from the top of Lily's source tree, type
53 which leaves your patch as F<./patch-0.1.48.jcn1>.
55 If you didn't configure Lily using --srcdir, you can do:
59 tar-ball: ../patches/patch-0.1.48.jcn1.gz
60 patch: ../patches/patch-0.1.48.jcn1.gz
61 updeet: ../test/updeet
65 For creating a patch you need
71 All items mentioned in F<INSTALL>. You're not going to send a patch
72 that you haven't even built, right?
80 Python (version 1.4 or newer).
81 You can of course make a patch by hand, which would go something like:
85 diff -urN lilypond-0.1.48 lilypond-0.1.48.jcn1 > patch-0.1.48.jcn1
87 but there are handy python scripts available. If you're doing development,
88 you'll need Python for other LilyPond scripts anyway.
92 The Lily directory structure, which looks like:
101 =head1 APPLYING PATCHES
103 If you're following LilyPond development regularly, you probably want to
104 download just the patch for each subsequent release.
105 After downloading the patch (into the patches directory, of course), simply
108 gzip -dc ../patches/patch-0.1.49.gz | patch -p1 -E
110 and don't forget to make automatically generated files:
117 If you're not very quick with sending your patch, there's a good chance
118 that an new release of LilyPond comes available. In such a case (and
119 sometimes for other unkown reasons :-), the maintainer will probably ask
120 you to make a new patch against the latest release.
121 Your best bet is to download the latest release, and apply your patch
122 against this new source tree:
125 gzip -dc ../patches/patch-0.1.48.jcn1.gz | patch -p1 -E
129 Then, make a patch as shown above.
131 1) patches don't include automatically generated files, i.e. F<configure>
132 and files generated by F<configure>.
