Subject: [PATCH] Add sysroot option to fc-cache and fc-cat
|
|
|
|
Whether one needs to generate the font cache offline and then deploy the
|
|
image to a target or do some testing in a separate rootfs, the sysroot
|
|
option will facilitate that.
|
|
|
|
Suppose you've got a rootfs in the following directory:
|
|
/path/to/test/rootfs. In order to contain the fc-cache generation to
|
|
that particular directory, the following command can be used:
|
|
|
|
fc-cache --sysroot=/path/to/test/rootfs
|
|
|
|
That will make fc-cache to prepend the sysroot directory to all paths
|
|
during scanning. For example, instead of searching /etc/fonts/ directory
|
|
for configuration files, it will look in /path/to/test/rootfs/etc/fonts.
|
|
The paths found in fonts.conf will also be prepended with the sysroot.
|
|
|
|
However, the generated cache files will not contain any references to
|
|
sysroot. This way, one can generate the font cache offline and then deploy
|
|
the image to target. Or, simply, use it for various tests without
|
|
polluting the system/user cache files.
|
|
|
|
In order to inspect the cache generated using the sysroot option, one
|
|
has to use fc-cat like below (for example):
|
|
|
|
fc-cat --sysroot=/path/to/test/rootfs
|
|
/path/to/test/rootfs/var/cache/fontconfig/*
|
|
