# Purpose
|
||||||
|
#
|
||||||
|
# Comments and uncomments #define lines in the given header file and optionally
|
||||||
|
# sets their value or can get the value. This is to provide scripting control of
|
||||||
|
# what preprocessor symbols, and therefore what build time configuration flags
|
||||||
|
# are set in the 'config.h' file.
|
||||||
|
#
|
||||||
|
# Usage: config.pl [-f <file> | --file <file>] [-o | --force]
|
||||||
|
# [set <symbol> <value> | unset <symbol> | get <symbol> |
|
||||||

Commands
|
||||||
|
set <symbol> [<value>] - Uncomments or adds a #define for the <symbol> to
|
||||||
|
the configuration file, and optionally making it
|
||||||
|
of <value>.
|
||||||
|
If the symbol isn't present in the file an error
|
||||||
|
is returned.
|
||||||
|
unset <symbol> - Comments out the #define for the given symbol if
|
||||||
|
present in the configuration file.
|
||||||
|
get <symbol> - Finds the #define for the given symbol, returning
|
||||||
|
an exitcode of 0 if the symbol is found, and 1 if
|
||||||
|
not. The value of the symbol is output if one is
|
||||||
|
specified in the configuration file.
|
||||||
|
full - Uncomments all #define's in the configuration file
|
||||||
|
excluding some reserved symbols, until the
|
||||||
|
'Module configuration options' section
|
||||||
|
realfull - Uncomments all #define's with no exclusions
|
||||||
|
baremetal - Sets full configuration suitable for baremetal build.
|
||||||
|
|
||||||
|
Options
|
||||||
|
-f | --file <filename> - The file or file path for the configuration file
|
||||||
|
to edit. When omitted, the following default is
|
||||||
|
used:
|
||||||
|
$config_file
|
||||||
|
-o | --force - If the symbol isn't present in the configuration
|
||||||
|
file when setting its value, a #define is
|
||||||
|
appended to the end of the file.
