GTK4-UPDATE-ICON-CACHE() GTK4-UPDATE-ICON-CACHE()
NAME
gtk4-update-icon-cache - Icon theme caching utility
SYNOPSIS
gtk4-update-icon-cache [OPTIONS...] <PATH>
DESCRIPTION
gtk4-update-icon-cache creates mmap(2)-able cache files for icon
themes.
It expects to be given the PATH to an icon theme directory containing
an index.theme, e.g. /usr/share/icons/hicolor, and writes a
icon-theme.cache containing cached information about the icons in the
directory tree below the given directory.
GTK can use the cache files created by gtk4-update-icon-cache to avoid
a lot of system call and disk seek overhead when the application
starts. Since the format of the cache files allows them to be shared
across multiple processes, for instance using the POSIX mmap(2) system
call, the overall memory consumption is reduced as well.
OPTIONS
-f, --force
Overwrite an existing cache file even if it appears to be
up-to-date.
-t, --ignore-theme-index
Don't check for the existence of index.theme in the icon theme di-
rectory. Without this option, gtk4-update-icon-cache refuses to
create an icon cache in a directory which does not appear to be the
toplevel directory of an icon theme.
-i, --index-only
Don't include image data in the cache.
--include-image-data
Include image data in the cache.
-c, --source <NAME>
Output a C header file declaring a constant NAME with the contents
of the icon cache.
-q, --quiet
Turn off verbose output.
-v, --validate
Validate existing icon cache.
