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. + +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 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 (default); or + 2) ``file`` -> write to a file to the temporary + directory (the name will be chosen + automatically. + +--version, -V Show version numbers of components as well as + some basic information 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 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*. + +SEE ALSO +======================================================================= + +**luatex** (1), **lua** (1) + +* ``texdoc luaotfload`` to display the manual for the *Luaotfload* + package +* Luaotfload development ``_ +* LuaLaTeX mailing list ``_ +* LuaTeX ``_ +* ConTeXt ``_ +* Luaotfload on CTAN ``_ + +BUGS +======================================================================= + +Tons, probably. + +AUTHORS +======================================================================= + +*Luaotfload* is maintained by the LuaLaTeX dev team +(``__). +The fontloader code is provided by Hans Hagen of Pragma ADE, Hasselt +NL (``__). + +This manual page was written by Philipp Gesang +. + -- cgit v1.2.3
