Usage: $prg [-user|-sys] [OPTION] ... [COMMAND]
or: $prg-sys [OPTION] ... [COMMAND]
or: $prg-user [OPTION] ... [COMMAND]
or: mktexfmt FORMAT.fmt|BASE.base|FMTNAME.EXT
Rebuild and manage TeX fmts and Metafont bases, collectively called
"formats" here. (MetaPost no longer uses the past-equivalent "mems".)
If the command name ends in mktexfmt, only one format can be created.
The only options supported are --help and --version, and the command
line must be either a format name, with extension, or a plain name that
is passed as the argument to --byfmt (see below). The full name of the
generated file (if any) is written to stdout, and nothing else.
If not operating in mktexfmt mode, exactly one command must be given,
extensions should generally not be specified, no non-option arguments
are allowed, and multiple formats can be generated, as follows.
By default, the return status is zero if all formats requested are
successfully built, else nonzero.
Options:
--sys use TEXMFSYS{VAR,CONFIG}
--user use TEXMF{VAR,CONFIG}
--cnffile FILE read FILE instead of fmtutil.cnf
(can be given multiple times, in which case
all the files are used)
--fmtdir DIR write formats under DIR instead of TEXMF[SYS]VAR
--no-engine-subdir don't use engine-specific subdir of the fmtdir
--no-error-if-no-format exit successfully if no format is selected
--no-error-if-no-engine=ENGINE1,ENGINE2,...
exit successfully even if a required engine
is missing, if it is included in the list.
--no-strict exit successfully even if a format fails to build
--nohash don't update ls-R files
--recorder pass the -recorder option and save .fls files
--quiet be silent
--catcfg (does nothing, exists for compatibility)
--dolinks (does nothing, exists for compatibility)
--force (does nothing, exists for compatibility)
--test (does nothing, exists for compatibility)
Commands:
--all recreate all format files
--missing create all missing format files
--refresh recreate only existing format files
--byengine ENGINE (re)create formats built with ENGINE
--byfmt FORMAT (re)create format FORMAT
--byhyphen HYPHENFILE (re)create formats that depend on HYPHENFILE
--enablefmt FORMAT[/ENGINE] enable FORMAT, as built with ENGINE
--disablefmt FORMAT[/ENGINE] disable FORMAT, as built with ENGINE
If multiple formats have the same name and
different engines, /ENGINE specifier is required.
--listcfg list (enabled and disabled) configurations,
filtered to available formats
--showhyphen FORMAT print name of hyphen file for FORMAT
--version show version information and exit
--help show this message and exit
Explanation of trees and files normally used:
If --cnffile is specified on the command line (possibly multiple
times), its value(s) are used. Otherwise, fmtutil reads all the
fmtutil.cnf files found by running \`kpsewhich -all fmtutil.cnf', in the
order returned by kpsewhich.
In any case, if multiple fmtutil.cnf files are found, all the format
definitions found in all the fmtutil.cnf files are merged.
Thus, if fmtutil.cnf files are present in all trees, and the default
layout is used as shipped with TeX Live, the following files are
read, in the given order.
For fmtutil-sys:
TEXMFSYSCONFIG \$TEXLIVE/YYYY/texmf-config/web2c/fmtutil.cnf
TEXMFSYSVAR \$TEXLIVE/YYYY/texmf-var/web2c/fmtutil.cnf
TEXMFLOCAL \$TEXLIVE/texmf-local/web2c/fmtutil.cnf
TEXMFDIST \$TEXLIVE/YYYY/texmf-dist/web2c/fmtutil.cnf
For fmtutil-user:
TEXMFCONFIG \$HOME/.texliveYYYY/texmf-config/web2c/fmtutil.cnf
TEXMFVAR \$HOME/.texliveYYYY/texmf-var/web2c/fmtutil.cnf
TEXMFHOME \$HOME/texmf/web2c/fmtutil.cnf
TEXMFSYSCONFIG \$TEXLIVE/YYYY/texmf-config/web2c/fmtutil.cnf
TEXMFSYSVAR \$TEXLIVE/YYYY/texmf-var/web2c/fmtutil.cnf
TEXMFLOCAL \$TEXLIVE/texmf-local/web2c/fmtutil.cnf
TEXMFDIST \$TEXLIVE/YYYY/texmf-dist/web2c/fmtutil.cnf
(where YYYY is the TeX Live release version).
According to the actions, fmtutil might write to one of the given files
or create a new fmtutil.cnf, described further below.
Where formats are written:
By default, format files are (re)written in TEXMFSYSVAR/ENGINE by
fmtutil-sys, and TEXMFVAR/ENGINE by fmtutil, where /ENGINE is a
subdirectory named for the engine used, such as "pdftex".
If the --fmtdir=DIR option is specified, DIR is used instead of
TEXMF[SYS]VAR, but the /ENGINE subdir is still used by default.
In any case, if the --no-engine-subdir option is specified, the
/ENGINE subdir is omitted.
Where configuration changes are saved:
If config files are given on the command line, then the first one
given will be used to save any changes from --enable or --disable.
If the config files are taken from kpsewhich output, then the
algorithm is more complex:
1) If \$TEXMFCONFIG/web2c/fmtutil.cnf or \$TEXMFHOME/web2c/fmtutil.cnf
appears in the list of used files, then the one listed first by
kpsewhich --all (equivalently, the one returned by kpsewhich
fmtutil.cnf), is used.
2) If neither of the above two are present and changes are made, a
new config file is created in \$TEXMFCONFIG/web2c/fmtutil.cnf.
In general, the idea is that if a given config file is not writable, a
higher-level one can be used. That way, the distribution's settings
can be overridden system-wide using TEXMFLOCAL, and system settings
can be overridden again in a particular user's TEXMFHOME.
Resolving multiple definitions of a format:
If a format is defined in more than one config file, then the definition
coming from the first-listed fmtutil.cnf is used.
Disabling formats:
fmtutil.cnf files with higher priority (listed earlier) can disable
formats in lower priority (listed later) fmtutil.cnf files by
writing a line like
\#! <fmtname> <enginename> <hyphen> <args>
in the higher-priority fmtutil.cnf file. The \#! must be at the
beginning of the line, with at least one space or tab afterward, and
there must be whitespace between each word on the list.
For example, you can disable the luajitlatex format by creating
the file \$TEXMFCONFIG/web2c/fmtutil.cnf with the line
#! luajitlatex luajittex language.dat,language.dat.lua lualatex.ini
(As it happens, the luajittex-related formats are precisely why the
--no-error-if-no-engine option exists, since luajittex cannot be
compiled on all platforms.)
fmtutil-user (fmtutil -user) vs. fmtutil-sys (fmtutil -sys):
When fmtutil-sys is run or the command line option -sys is used,
TEXMFSYSCONFIG and TEXMFSYSVAR are used instead of TEXMFCONFIG and
TEXMFVAR, respectively. This is the primary difference between
fmtutil-sys and fmtutil-user.
See http://tug.org/texlive/scripts-sys-user.html for details.
Other locations may be used if you give them on the command line, or
these trees don't exist, or you are not using the original TeX Live.
Supporting development binaries
If an engine name ends with "-dev", formats are created in
the respective directory with the -dev stripped. This allows for
easily running development binaries in parallel with the released
binaries.
