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. ---------------------------------------------------------------------------- #!/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>

== 'make' tips
This is a collection of tips that help you make the most of Buildroot.
.Configuration searches:
The +make *config+ commands offer a search tool. Read the help message in
the different frontend menus to know how to use it:
* in _menuconfig_, the search tool is called by pressing +/+;
* in _xconfig_, the search tool is called by pressing +Ctrl+ + +f+.
The result of the search shows the help message of the matching items.
.Display all commands executed by make:
--------------------
$ make V=1 <target>
--------------------
.Display all available targets:
--------------------
$ make help
--------------------
Not all targets are always available,
some settings in the +.config+ file may hide some targets:
* +busybox-menuconfig+ and +busybox-savedefconfig+ only work when
+busybox+ is enabled;
* +linux-menuconfig+ and +linux-savedefconfig+ only work when
+linux+ is enabled;
* +uclibc-menuconfig+ is only available when the uClibc C library is
selected in the internal toolchain backend;
* +barebox-menuconfig+ and +barebox-savedefconfig+ only work when the
+barebox+ bootloader is enabled.
.Cleaning:
Explicit cleaning is required when any of the architecture or toolchain
configuration options are changed.
To delete all build products (including build directories, host, staging
and target trees, the images and the toolchain):
--------------------
$ make clean
--------------------
.Generating the manual:
The present manual sources are located in the 'docs/manual' directory.
To generate the manual:
---------------------------------
$ make manual-clean
$ make manual
---------------------------------
The manual outputs will be generated in 'output/docs/manual'.
.Notes
- A few tools are required to build the documentation (see:
xref:requirement-optional[]).
.Reseting Buildroot for a new target:
To delete all build products as well as the configuration:
--------------------
$ make distclean
--------------------
.Notes
If +ccache+ is enabled, running +make clean+ or +distclean+ does
not empty the compiler cache used by Buildroot. To delete it, refer
to xref:ccache[].
