DESCRIPTION

       luaotfload-tool accesses the font names  database  that  is  required  by  the  Luaotfload
       package. There are two general modes: update and query.

       • update:  update the database or rebuild it entirely;

       • query:   resolve a font name or display close matches.

       Note  that  if  the  script  is  named mkluatexfontdb it will behave like earlier versions
       (<=1.3) and always update the database first. Also, the verbosity level will be set to 2.

OPTIONS

update mode
--update, -u
Update the database; indexes new fonts.

--force, -f
Force rebuilding of the database; re-indexes all fonts.

--no-reload, -n
Suppress auto-updates to the database (e.g. when --find is passed an unknown
name).

--no-strip
Do not strip redundant information after building the database. Warning: this will
inflate the index to about two to three times the normal size.

--no-compress, -c
Do not filter the plain text version of the font index through gzip. Useful for
debugging if your editor is built without zlib.

--prefer-texmf, -p
Organize the file name database in a way so that it prefer fonts in the TEXMF tree
over system fonts if they are installed in both.

--max-fonts=N
Process at most N font files, including fonts already indexed in the count.

--formats=EXTENSIONS
Extensions of the font files to index. Where EXTENSIONS is a comma-separated list
of supported file extensions (otf, ttf, ttc, dfont, pfa, and pfb). If the list is
prefixed with a + sign, the given list is added to the currently active one; -
subtracts. Default: otf,ttf,ttc,dfont. Examples:

1. --formats=-ttc,ttf would skip TrueType fonts and font collections;

2. --formats=otf would scan only OpenType files;

3. --formats=+pfb includes binary Postscript files. Warning: with a standard TeX
Live installation this will grow the database considerably and slow down font
indexing.

--dry-run, -D
Don’t load fonts, scan directories only. (For debugging file system related
issues.)

query mode
--find=NAME
Resolve a font name; this looks up <name> in the database and prints the file name
it is mapped to. --find also understands request syntax, i.e. --find=file:foo.otf
checks whether foo.otf is indexed.

--fuzzy, -F
Show approximate matches to the file name if the lookup was unsuccessful (requires
--find).

--info, -i
Display basic information to a resolved font file (requires --find).

--inspect, -I
Display detailed information by loading the font and analyzing the font table; very
slow! For the meaning of the returned fields see the LuaTeX documentation.
(requires --find).

--warnings, -w
Print the warnings generated by the fontloader library (assumes -I). Automatically
enabled if the verbosity level exceeds 2.

--show-blacklist, -b
Show blacklisted files (not directories).

--list=CRITERION
Show entries, where CRITERION is one of the following:

1. the character *, selecting all entries;

2. a field of a database entry, for instance version or format*, according to which
the output will be sorted. Information in an unstripped database (see the
option --no-strip above) is nested: Subfields of a record can be addressed using
the -> separator, e. g. file->location, style->units_per_em, or
names->sanitized->english->prefmodifiers. NB: shell syntax requires that
arguments containing -> be properly quoted!

3. an expression of the form field:value to limit the output to entries whose field
matches value.

For example, in order to output file names and corresponding versions, sorted by
the font format:

./luaotfload-tool.lua --list="format" --fields="file->base,version"

This prints:

otf latinmodern-math.otf Version 1.958
otf lmromancaps10-oblique.otf 2.004
otf lmmono8-regular.otf 2.004
otf lmmonoproplt10-bold.otf 2.004
otf lmsans10-oblique.otf 2.004
otf lmromanslant8-regular.otf 2.004
otf lmroman12-italic.otf 2.004
otf lmsansdemicond10-oblique.otf 2.004
...

--fields=FIELDS
Comma-separated list of fields that should be printed. Information in an
unstripped database (see the option --no-strip above) is nested: Subfields of a
record can be addressed using the -> separator, e. g. file->location,
style->units_per_em, or names->sanitized->english->subfamily. The default is
plainname,version*. (Only meaningful with --list.)

font and lookup caches
--flush-lookups
Clear font name lookup cache (experimental).

--cache=DIRECTIVE
Cache control, where DIRECTIVE is one of the following:

1. purge -> delete Lua files from cache;

2. erase -> delete Lua and Luc files from cache;

3. show -> print stats.

miscellaneous
--verbose=N, -v
Set verbosity level to n or the number of repetitions of -v.

--quiet
No verbose output (log level set to zero).

--log=CHANNEL
Redirect log output (for database troubleshooting), where CHANNEL can be

1. stdout -> all output will be dumped to the terminal; or

2. file -> write to a file to the temporary directory (the name will be chosen
automatically (experimental!).

--version, -V
Show version info of components and exit.

--help, -h
Show help message and exit.

--diagnose=CHECK
Run the diagnostic procedure CHECK. Available procedures are:

1. files -> check Luaotfload files for modifications;

2. permissions -> check permissions of cache directories and files;

environment -> print relevant
environment and kpse variables;

4. repository -> check the git repository for new releases,

5. index -> check database, display information about it.

Procedures can be chained by concatenating with commas, e.g.
--diagnose=files,permissions. Specify thorough to run all checks.

FILES

       The     font     name     database     is     usually    located    in    the    directory
       texmf-var/luatex-cache/generic/names/ ($TEXMFCACHE as set in texmf.cnf) of your  TeX  Live
       distribution  as  a zlib-compressed file luaotfload-names.lua.gz.  The experimental lookup
       cache will be created as luaotfload-lookup-cache.lua in the  same  directory.   These  Lua
       tables  are  not  used  directly by Luaotfload, though.  Instead, they are compiled to Lua
       bytecode which is written to corresponding files with  the  extension  .luc  in  the  same
       directory.   When modifying the files by hand keep in mind that only if the bytecode files
       are missing will Luaotfload use the plain version instead.  Both kinds of files  are  safe
       to delete, at the cost of regenerating them with the next run of LuaTeX.

BUGS

       Tons, probably.
