exec 'python3', $py, @ARGV

#
|

# 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> |
|
|
||||||
# full | realfull]
|
|
||||||
#
|
|
||||||
# Full usage description provided below.
|
|
||||||
#
|
|
||||||
# The following options are disabled instead of enabled with "full".

[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.
