Patches
Patches are applied in filename order, with the -p1
option. Creation by
diff -Naur old_dir new_dir
or
diff -Nau old_file new_file
works well. They should be named 01-explanation.patch
, where the initial
numbers increase in the order for patches to be applied, and explanation
is a
short title giving some inkling of the patch’s purpose. Additionally, the first
few lines of the patch (before the
--- foo/1.0/file.bad
+++ foo/1.0/file.good
lines) should contain an explanation of why the patch is necessary. GoboLinux avoids patches to add features or optimizations; patches should fix compilation or installation, or true bugs.
Dynamic patches
These patches are modified by Compile prior to being applied. They should be
named 01-explanation.patch.in
. Dynamic variables may be
used, prefixed with the string @%Compile_
and postfixed with %@
. Such
variables include (where the Program being compiled has some dependency Foo
):
@%Compile_target%@
@%Compile_settings_target%@
@%Compile_variable_target%@
@%Compile_foo_path%@
@%Compile_foo_settings_path%@
@%Compile_foo_variable_path%@
