8 # @BLURB: helper functions to install systemd units
9 # @DESCRIPTION:
10 # This eclass provides a set of functions to install unit files for
11 # sys-apps/systemd within ebuilds.
12 # @EXAMPLE:
13 #
14 # @CODE
15 # inherit autotools-utils systemd
16 #
17 # src_configure() {
18 # local myeconfargs=(
19 # --enable-foo
20 # --disable-bar
21 # )
22 #
23 # systemd_to_myeconfargs
24 # autotools-utils_src_configure
25 # }
26 # @CODE

46 # Install systemd unit(s). Uses doins, thus it is fatal in EAPI 4
47 # and non-fatal in earlier EAPIs.

72 # @USAGE: target service
73 # @DESCRIPTION:

76 # EAPIs.

90 # @FUNCTION: systemd_with_unitdir
91 # @USAGE: [configure option]
92 # @DESCRIPTION:
93 # Output '--with-systemdsystemunitdir' as expected by systemd-aware configure
94 # scripts. This function always succeeds. Its output may be quoted in order
95 # to preserve whitespace in paths. systemd_to_myeconfargs() is preferred over
96 # this function.
97 #
98 # If upstream does use invalid configure option to handle installing systemd
99 # units (e.g. `--with-systemdunitdir'), you can pass the 'suffix' as an optional
100 # argument to this function (`$(systemd_with_unitdir systemdunitdir)'). Please
101 # remember to report a bug upstream as well.

108
109 # @FUNCTION: systemd_to_myeconfargs
110 # @DESCRIPTION:
111 # Add '--with-systemdsystemunitdir' as expected by systemd-aware configure
112 # scripts to the myeconfargs variable used by autotools-utils eclass. Handles
113 # quoting automatically.
