NAME¶
guards - select from a list of files guarded by conditionsSYNOPSIS¶
guards [--prefix=dir] [--path=dir1:dir2:...] [--default=<0|1>] [--check|--list] [--invert-match] [--with-guards] [--config=<file>] symbol ...DESCRIPTION¶
The script reads a configuration file that may contain so-called guards, file names, and comments, and writes those file names that satisfy all guards to standard output. The script takes a list of symbols as its arguments. Each line in the configuration file is processed separately. Lines may start with a number of guards. The following guards are defined:+xxx Include the file(s) on this line if the
symbol xxx is defined.
- xxx Exclude the file(s) on this line if the symbol xxx is
defined.
+! xxx Include the file(s) on this line if the symbol xxx is not
defined.
-! xxx Exclude the file(s) on this line if the symbol xxx is not
defined.
- Exclude this file. Used to avoid spurious --check messages.
The guards are processed left to right. The last guard that matches determines
if the file is included. If no guard is specified, the --default
setting determines if the file is included.
If no configuration file is specified, the script reads from standard input.
The --check option is used to compare the specification file against the
file system. If files are referenced in the specification that do not exist,
or if files are not enlisted in the specification file warnings are printed.
The --path option can be used to specify which directory or directories
to scan. Multiple directories are separated by a colon (":")
character. The --prefix option specifies the location of the files.
Use --list to list all files independent of any rules. Use
--invert-match to list only the excluded patches. Use
--with-guards to also include all inclusion and exclusion rules.
