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.
--compress Filter plain text version of font index through
gzip.
--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.
--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 number 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;
3) ``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
``luaotfload-names.lua``. The experimental lookup cache will be
created as ``luaotfload-lookup-cache.lua`` in the same directory.
Both files are safe to delete, at the cost of regenerating them with
the next run of *LuaTeX*.
