manual: use one-line titles instead of two-line titles (trivial)
Asciidoc supports two syntaxes for section titles: two-line titles (title
plus underline consisting of a particular symbol), and one-line titles
(title prefixed with a specific number of = signs).
The two-line title underlines are:
Level 0 (top level): ======================
Level 1: ----------------------
Level 2: ~~~~~~~~~~~~~~~~~~~~~~
Level 3: ^^^^^^^^^^^^^^^^^^^^^^
Level 4 (bottom level): ++++++++++++++++++++++
and the one-line title prefixes:
= Document Title (level 0) =
== Section title (level 1) ==
=== Section title (level 2) ===
==== Section title (level 3) ====
===== Section title (level 4) =====
The buildroot manual is currenly using the two-line titles, but this has
multiple disadvantages:
- asciidoc also uses some of the underline symbols for other purposes (like
preformatted code, example blocks, ...), which makes it difficult to do
mass replacements, such as a planned follow-up patch that needs to move
all sections one level down.
- it is difficult to remember which level a given underline symbol (=-~^+)
corresponds to, while counting = signs is easy.
This patch changes all two-level titles to one-level titles in the manual.
The bulk of the change was done with the following Python script, except for
the level 1 titles (-----) as these underlines are also used for literal
code blocks.
This patch only changes the titles, no other changes. In
adding-packages-directory.txt, I did add missing newlines between some
titles and their content.

=== Hooks available in the various build steps
|
2013-11-07 11:41:23 +01:00
|
|
|
|
|
|
|
|
The generic infrastructure (and as a result also the derived autotools
|
|
|
|
|
and cmake infrastructures) allow packages to specify hooks.
|
|
|
|
|
These define further actions to perform after existing steps.
|
|
|
|
|
Most hooks aren't really useful for generic packages, since the +.mk+
|
|
|
|
|
file already has full control over the actions performed in each step
|
|
|
|
|
of the package construction.
|
|
|
|
|
|
|
|
|
|
The following hook points are available:

==== Using the +POST_RSYNC+ hook
|
2013-11-07 11:41:24 +01:00
|
|
|
The +POST_RSYNC+ hook is run only for packages that use a local source,
|
|
|
|
|
either through the +local+ site method or the +OVERRIDE_SRCDIR+
|
|
|
|
|
mechanism. In this case, package sources are copied using +rsync+ from
|
|
|
|
|
the local location into the buildroot build directory. The +rsync+
|
|
|
|
|
command does not copy all files from the source directory, though.
|
|
|
|
|
Files belonging to a version control system, like the directories
|
|
|
|
|
+.git+, +.hg+, etc. are not copied. For most packages this is
|
|
|
|
|
sufficient, but a given package can perform additional actions using
|
|
|
|
|
the +POST_RSYNC+ hook.
|
|
|
|
|
|
|
|
|
|
In principle, the hook can contain any command you want. One specific
|
|
|
|
|
use case, though, is the intentional copying of the version control
|
|
|
|
|
directory using +rsync+. The +rsync+ command you use in the hook can, among
|
|
|
|
|
others, use the following variables:
|
|
|
|
|
|
|
|
|
|
* +$(SRCDIR)+: the path to the overridden source directory
|
|
|
|
|
* +$(@D)+: the path to the build directory

|
|
==== Target-finalize hook
|
|
|
|
|
|
|
|
|
|
Packages may also register hooks in +LIBFOO_TARGET_FINALIZE_HOOKS+.
|
|
|
|
|
These hooks are run after all packages are built, but before the
|
|
|
|
|
filesystem images are generated. They are seldom used, and your
|
|
|
|
|
package probably do not need them.
