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. ---------------------------------------------------------------------------- #!/usr/bin/env python import sys import mmap import re for input in sys.argv[1:]: f = open(input, 'r+') f.flush() s = mmap.mmap(f.fileno(), 0) # Level 0 (top level): ====================== = # Level 1: ---------------------- == # Level 2: ~~~~~~~~~~~~~~~~~~~~~~ === # Level 3: ^^^^^^^^^^^^^^^^^^^^^^ ==== # Level 4 (bottom level): ++++++++++++++++++++++ ===== def replace_title(s, symbol, replacement): pattern = re.compile(r'(.+\n)\%s{2,}\n' % symbol, re.MULTILINE) return pattern.sub(r'%s \1' % replacement, s) new = s new = replace_title(new, '=', '=') new = replace_title(new, '+', '=====') new = replace_title(new, '^', '====') new = replace_title(new, '~', '===') #new = replace_title(new, '-', '==') s.seek(0) s.write(new) s.resize(s.tell()) s.close() f.close() ---------------------------------------------------------------------------- Signed-off-by: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

== Coding style
|
|
|
|
Overall, these coding style rules are here to help you to add new files in
|
|
Buildroot or refactor existing ones.
|
|
|
|
If you slightly modify some existing file, the important thing is
|
|
to keep the consistency of the whole file, so you can:
|
|
|
|
* either follow the potentially deprecated coding style used in this
|
|
file,
|
|
|
|
* or entirely rework it in order to make it comply with these rules.

|
=== +Config.in+ file
|
|
|
|
+Config.in+ files contain entries for almost anything configurable in
|
|
Buildroot.
|
|
|
|
An entry has the following pattern:
|
|
|
|
---------------------
|
|
config BR2_PACKAGE_LIBFOO
|
|
bool "libfoo"
|
|
depends on BR2_PACKAGE_LIBBAZ
|
|
select BR2_PACKAGE_LIBBAR
|
|
help
|
|
This is a comment that explains what libfoo is.
|
|
|
|
http://foosoftware.org/libfoo/
|
|
---------------------
|
|
|
|
* The +bool+, +depends on+, +select+ and +help+ lines are indented
|
|
with one tab.
|
|
|
|
* The help text itself should be indented with one tab and two
|
|
spaces.
|
|
|
|
The +Config.in+ files are the input for the configuration tool
|
|
used in Buildroot, which is the regular _Kconfig_. For further
|
|
details about the _Kconfig_ language, refer to
|
|
http://kernel.org/doc/Documentation/kbuild/kconfig-language.txt[].

|
|
|
=== The +.mk+ file
|
|
|
|
* Header: The file starts with a header. It contains the module name,
|
|
preferably in lowercase, enclosed between separators made of 80 hashes. A
|
|
blank line is mandatory after the header:

################################################################################
|
|
---------------------
|
|
+
|
|
* Assignment: use +=+ preceded and followed by one space:
|
|
+
|
|
---------------------
|
|
LIBFOO_VERSION = 1.0
|
|
LIBFOO_CONF_OPT += --without-python-support
|
|
---------------------
|
|
+
|
|
Do not align the +=+ signs.
|
|
|
|
* Indentation: use tab only:
|
|
+
|
|
---------------------
|
|
define LIBFOO_REMOVE_DOC
|
|
$(RM) -fr $(TARGET_DIR)/usr/share/libfoo/doc \
|
|
$(TARGET_DIR)/usr/share/man/man3/libfoo*
|
|
endef
|
|
---------------------
|
|
+
|
|
Note that commands inside a +define+ block should always start with a tab,
|
|
so _make_ recognizes them as commands.
|
|
|
|
* Optional dependency:
|
|
|
|
** Prefer multi-line syntax.

LIBFOO_DEPENDENCIES += $(if $(BR2_PACKAGE_PYTHON),python,)
|
|
---------------------
|
|
|
|
** Keep configure options and dependencies close together.
|
|
|
|
* Optional hooks: keep hook definition and assignment together in one
|
|
if block.
