fntldr

fntldr can temporarily install (or "load") fonts into the system. It is also an easier-to-use replacement of FontLoader, FontLoaderSub and ListAssFonts.

The program supports GNU/Linux (using Fontconfig) and Windows.

Usage

Notice: Do not force kill the process, or fonts and temporary files won't be properly cleaned.

Default cache location is {user cache dir}/fntldr/fntldr_cache.bin.

Add --help after a subcommand for more information.

Load font files

fntldr load [--dir DIRECTORY]... [--recurse DIRECTORY]... [FONT_FILE]...

Load used fonts in (A)SSA subtitles

fntldr load-by [--dir DIRECTORY]... [--recurse DIRECTORY]... [--cache CACHE] [--font-list]

When --cache is not specified, it first try to load ./fntldr_cache.bin, if not present, then try default location.

Build index cache

fntldr index [--dir DIRECTORY]... [--recurse DIRECTORY]... [--cache CACHE] [--portable] [--rebuild]

By default, it tries to load cache from default location and update it, or you can specify --cache to operate on given cache file.

List used fonts in (A)SSA subtitles

fntldr list [--dir DIRECTORY]... [--recurse DIRECTORY]... [--cache [CACHE]] [--font-list] [--export DIRECTORY]

Font reexporting is not yet available on Windows.

Delete index cache file

fntldr clear [--cache CACHE]

Drag-and-drop Compatibility

Rename the executable to fontloader / fontloadersub / listassfonts (case insensitive) to use DnD compatibility modes.

FontLoader mode

fontloader [FONT_FILE]...

Equivalent to fntldr load ... or fntldr load --dir .. If running without any parameters, it loads all font files in the current working directory.

FontLoaderSub mode

fontloadersub [SUBTITLES_DIR]...

Equivalent to fntldr load-by --recurse ... if cache is found at ./fntldr_cache.bin. If the index cache is not found, it would recursively scans the current working directory for font files and build the cache, like running:

fntldr index --recurse . --cache . --portable

ListAssFonts mode

listassfonts [SUBTITLES_DIR]...

Equivalent to fntldr list --recurse ....

The program currently does not have all the features as in ListAssFonts, and they will be added in fntldr list, this mode is just for simple listing.

Problems with font installation check using Fontconfig

The program may load unnecassary fonts if you have aliases in your config, and fntldr list may mark them as not installed. So sad!
