# In case `local' is not supported by the shell, provide a function

Usage: $program [OPTION]... FILE...
|
||
or: texi2pdf [OPTION]... FILE...
|
||
or: pdftexi2dvi [OPTION]... FILE...
|
||
|
||
Run each Texinfo or (La)TeX FILE through TeX in turn until all
|
||
cross-references are resolved, building all indices. The directory
|
||
containing each FILE is searched for included files. The suffix of FILE
|
||
is used to determine its language ((La)TeX or Texinfo). To process
|
||
(e)plain TeX files, set the environment variable LATEX=tex.
|
||
|
||
In order to make texi2dvi a drop-in replacement of TeX/LaTeX in AUC-TeX,
|
||
the FILE may also be composed of the following simple TeX commands.
|
||
\`\\input{FILE}' the actual file to compile
|
||
\`\\nonstopmode' same as --batch
|
||
|
||
When invoked as \`texi2pdf' or \`pdftexi2dvi', or given the option --pdf
|
||
or --dvipdf, generate PDF output. Otherwise, generate DVI.
|
||
|
||
General options:
|
||
-b, --batch no interaction
|
||
-D, --debug turn on shell debugging (set -x)
|
||
-h, --help display this help and exit successfully
|
||
-o, --output=OFILE leave output in OFILE; only one input FILE is allowed
|
||
-q, --quiet no output unless errors (implies --batch)
|
||
-s, --silent same as --quiet
|
||
-v, --version display version information and exit successfully
|
||
-V, --verbose report on what is done
|
||
|
||
Output format:
|
||
--dvi output a DVI file [default]
|
||
--dvipdf output a PDF file via DVI (using a dvi-to-pdf program)
|
||
--html output an HTML file from LaTeX, using HeVeA
|
||
--info output an Info file from LaTeX, using HeVeA
|
||
-p, --pdf use pdftex or pdflatex for processing
|
||
--ps output a PostScript file via DVI (using dvips)
|
||
--text output a plain text file from LaTeX, using HeVeA
|
||
|
||
TeX tuning:
|
||
-@ use @input instead of \input for preloaded Texinfo
|
||
-e, -E, --expand force macro expansion using makeinfo
|
||
-I DIR search DIR for Texinfo files
|
||
-l, --language=LANG specify LANG for FILE, either latex or texinfo
|
||
--no-line-error do not pass --file-line-error to TeX
|
||
--shell-escape pass --shell-escape to TeX
|
||
--src-specials pass --src-specials to TeX
|
||
-t, --command=CMD insert CMD in copy of input file
|
||
or --texinfo=CMD multiple values accumulate
|
||
--translate-file=FILE use given charset translation file for TeX
|
||
|
||
Build modes:
|
||
--build=MODE specify the treatment of auxiliary files [$build_mode]
|
||
--tidy same as --build=tidy
|
||
-c, --clean same as --build=clean
|
||
--build-dir=DIR specify where the tidy compilation is performed;
|
||
implies --tidy;
|
||
defaults to TEXI2DVI_BUILD_DIRECTORY [$build_dir]
|
||
--mostly-clean remove the auxiliary files and directories
|
||
but not the output
|
||
--max-iterations=N don't process files more than N times [$max_iters]
|
||
|
||
The MODE specifies where the TeX compilation takes place, and, as a
|
||
consequence, how auxiliary files are treated. The build mode
|
||
can also be set using the environment variable TEXI2DVI_BUILD_MODE.
|
||
|
||
Valid MODEs are:
|
||
\`local' compile in the current directory, leaving all the auxiliary
|
||
files around. This is the traditional TeX use.
|
||
\`tidy' compile in a local *.t2d directory, where the auxiliary files
|
||
are left. Output files are copied back to the original file.
|
||
\`clean' same as \`tidy', but remove the auxiliary directory afterwards.
|
||
Every compilation therefore requires the full cycle.
|
||
|
||
Using the \`tidy' mode brings several advantages:
|
||
- the current directory is not cluttered with plethora of temporary files.
|
||
- clutter can be even further reduced using --build-dir=dir: all the *.t2d
|
||
directories are stored there.
|
||
- clutter can be reduced to zero using, e.g., --build-dir=/tmp/\$USER.t2d
|
||
or --build-dir=\$HOME/.t2d.
|
||
- the output file is updated after every successful TeX run, for
|
||
sake of concurrent visualization of the output. In a \`local' build
|
||
the viewer stops during the whole TeX run.
|
||
- if the compilation fails, the previous state of the output file
|
||
is preserved.
|
||
- PDF and DVI compilation are kept in separate subdirectories
|
||
preventing any possibility of auxiliary file incompatibility.
|
||
|
||
On the other hand, because \`tidy' compilation takes place in another
|
||
directory, occasionally TeX won't be able to find some files (e.g., when
|
||
using \\graphicspath): in that case, use -I to specify the additional
|
||
directories to consider.
|
||
|
||
The values of the BIBER, BIBTEX, DVIPDF, DVIPS, HEVEA, LATEX, MAKEINDEX,
|
||
MAKEINFO, PDFLATEX, PDFTEX, SED, T4HT, TEX, TEX4HT, TEXINDEX, and THUMBPDF_CMD
|
||
environment variables are used to run those commands, if they are set.
|
||
|
||
Regarding --dvipdf, if DVIPDF is not set in the environment, the
|
||
following programs are looked for (in this order): dvipdfmx dvipdfm
|
||
dvipdf dvi2pdf dvitopdf.
|
||
|
||
Any CMD strings are added after @setfilename for Texinfo input, or in
|
||
the first line for LaTeX input.
