6 # @MAINTAINER:
7 # base-system@gentoo.org
8 # @BLURB: many extra (but common) functions that are used in ebuilds
9 # @DESCRIPTION:
10 # The eutils eclass contains a suite of functions that complement
11 # the ones that ebuild.sh already contain. The idea is that the functions
12 # are not required in all ebuilds but enough utilize them to have a common
13 # home rather than having multiple ebuilds implementing the same thing.
14 #
15 # Due to the nature of this eclass, some functions may have maintainers
16 # different from the overall eclass!

22 # @FUNCTION: epause
23 # @USAGE: [seconds]
24 # @DESCRIPTION:
25 # Sleep for the specified number of seconds (default of 5 seconds). Useful when
26 # printing a message the user should probably be reading and often used in
27 # conjunction with the ebeep function. If the EPAUSE_IGNORE env var is set,
28 # don't wait at all.
29 epause() {
30 [[ -z ${EPAUSE_IGNORE} ]] && sleep ${1:-5}
31 }

33 # @FUNCTION: ebeep
34 # @USAGE: [number of beeps]
35 # @DESCRIPTION:
36 # Issue the specified number of beeps (default of 5 beeps). Useful when
37 # printing a message the user should probably be reading and often used in
38 # conjunction with the epause function. If the EBEEP_IGNORE env var is set,
39 # don't beep at all.

72 EPATCH_FORCE="no"
73
74 # This function is for bulk patching, or in theory for just one
75 # or two patches.
76 #
77 # It should work with .bz2, .gz, .zip and plain text patches.
78 # Currently all patches should be the same format.
79 #
80 # You do not have to specify '-p' option to patch, as it will
81 # try with -p0 to -p5 until it succeed, or fail at -p5.
82 #
83 # Above EPATCH_* variables can be used to control various defaults,
84 # bug they should be left as is to ensure an ebuild can rely on
85 # them for.
86 #
87 # Patches are applied in current directory.
88 #
89 # Bulk Patches should preferibly have the form of:
90 #
91 # ??_${ARCH}_foo.${EPATCH_SUFFIX}
92 #
93 # For example:
94 #
95 # 01_all_misc-fix.patch.bz2
96 # 02_sparc_another-fix.patch.bz2
97 #
98 # This ensures that there are a set order, and you can have ARCH
99 # specific patches.
100 #
101 # If you however give an argument to epatch(), it will treat it as a
102 # single patch that need to be applied if its a file. If on the other
103 # hand its a directory, it will set EPATCH_SOURCE to this.
