Commit 229455bc02b87f7128f190c4491b4ceffff38648 accidentally changed the separator between sed `s' command and its parameters from ':' to '/'. Revert this change.

2013-08-15scripts/config: use sed's POSIX interfaceClement Chauplannaz
Script `config' relies on extensions of `GNU sed', and is thus not working on all Unixes: - in-place edition of files (-i), which can be replaced with a temporary file; - extended-regexps (-r), which can be split into basic regexps; - single-line calls to `a' command, while some implementations require a leading newline before the parameter. Rewrite calls to `sed' to comply with POSIX interface, and move them to helper functions. Signed-off-by: Clement Chauplannaz <chauplac@gmail.com> Tested-by: "Yann E.

2013-06-18scripts/config: replace hard-coded script name by a dynamic valueClement Chauplannaz
The script `config' prints its name in usage() function. It is currently hard-coded to value `config'. However, the script may be reused under a different name in contexts other than the Linux Kernel. Replace the hard-coded value `config' by the name of the script at runtime.

2013-05-20scripts/config: fix assignment of parameters for short version of --*-after ↵Clement Chauplannaz
options When --*-after options are used, two parameters are parsed from the command-line before the adequate function is called: - the `before' option, after which the new option will be inserted, - the name of the option to enable/disable/modularise. With the short version of --*-after options (namely -E, -D, -M), the parsing step is not performed which leads to processing unset variables. Add options -E, -D, -M to the test that triggers assignment of parameters for --*-after options.

2012-06-28scripts/config: allow alternate prefix to config option symbolYann E. MORIN
While the Linux kernel uses 'CONFIG_' as a prefix to the config options symbols, many projects that use kconfig may use different prefixes, or even none at all. If the CONFIG_ environment variable is set, use it as the prefix (empty is a valid prefix). Otherwise, use the default prefix 'CONFIG_'. This matches the support for alternate prefixes in scripts/kconfig/lkc.h, which uses the same logic (albeit with a C define instead of an environment variable). Signed-off-by: "Yann E.

2012-06-28scripts/config: add option to not upper-case symbolsYann E. MORIN
Currently, scripts/config mangles the config option symbols to always be upper-case. While the Linux kernel almost exclusively uses upper-case symbols, there are still a few symbols with lower-case which this script can not handle: $ grep -r -E '^[[:space:]]*config[[:space:]]+[^[:space:]]*[[:lower:]][^[:space:]=.]*$' . |wc -l 173 (that's roughly 1.3% of the symbols in 3.5-rc1) Eg.: ./arch/arm/Kconfig:config VFPv3 ./arch/powerpc/platforms/Kconfig.cputype:config 40x ./arch/x86/Kconfig:config SCx200HR_TIMER ./drivers/video/console/Kconfig:config FONT_8x8 ./drivers/video/Kconfig:config NTSC_640x480 Also, other projects that use kconfig may allow for lower- or mixed-case symbols, and may find easier to reuse this script than implement each their own (potentially flawed) logic. For such a use-case, see: http://marc.info/?l=linux-kbuild&m=133409932115848&w=2 This patch adds a new option to keep the given case, and keep the current default to upper-case the symbols.

2012-05-16scripts/config: properly report and set string optionsYann E. MORIN
Currently, scripts/config removes the leading double-quote from string options, but leaves the trailing double-quote. Also, double-quotes in a string are escaped, but scripts/config does not unescape those when printing Finally, scripts/config does not escape double-quotes when setting string options. Eg. the current behavior: $ grep -E '^CONFIG_FOO=' .config CONFIG_FOO="Bar \"Buz\" Meh" $ ./scripts/config -s FOO Bar \"Buz\" Meh" $ ./scripts/config --set-str FOO 'Alpha "Bravo" Charlie' $ grep -E '^CONFIG_FOO=' .config CONFIG_FOO="Alpha "Bravo" Charlie" Fix those three, giving this new behavior: $ grep -E '^CONFIG_FOO=' .config CONFIG_FOO="Bar \"Buz\" Meh" $ ./scripts/config -s FOO Bar "Buz" Meh $ ./scripts/config --set-str FOO 'Alpha "Bravo" Charlie' $ grep -E '^CONFIG_FOO=' .config CONFIG_FOO="Alpha \"Bravo\" Charlie" Signed-off-by: "Yann E.

2009-01-07kconfig: add script to manipulate .config files on the command lineAndi Kleen
I often change single options in .config files. Instead of using an editor or one of the frontends it's convenient to do this from the command line. It's also useful to do from automated build scripts when building different variants from a base config file. I extracted most of the CONFIG manipulation code from one of my build scripts into a new shell script scripts/config The script is not integrated with the normal Kconfig machinery and doesn't do any checking against Kconfig files, but just manipulates that text format. This is always done at make time anyways. I believe this script would be a useful standard addition for scripts/* Sample usage: ./scripts/config --disable smp Disable SMP in .config file ./scripts/config --file otherdir/.config --module e1000e Enable E1000E as module in otherdir/.config ./scripts/config --state smp y Check state of config option CONFIG_SMP After merging into git please make scripts/config executable Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
