If an error occurs at the TeX stage, processing halts immediately and the tail of the log file is sent to stderr. version 0.14 2015-12-01 DL Writes `musixtex.log` and deletes other logfiles (except with -i) Hierarchy of extensions emphasized in usage() and consistently used elsewhere. Unknown option-like arguments reported and ignored, not treated as filenames Warnings and error messages generated by musixtex.lua start with respctively `!` and `!!`. version 0.13 2015-11-30 RDT Process .mtx and .pmx files (suggested by Dirk Laurie) exit_code is now an error count Use pmxab exit code to distinguish between errors and warnings version 0.12 2015-11-28 RDT Process .ltx files, with -l implied version 0.11 2015-07-16 RDT Automatic autosp preprocessing. version 0.10 2015-04-23 RDT Add -a option to preprocess using autosp version 0.9 2015-02-13 RDT Add an additional latex pass to resolve cross-references. Add -e0 option to dvips as given in musixdoc.tex Add -x option to call makeindex version 0.8 2014-05-18 RDT Add -g option version 0.7 2013-12-11 RDT Add -F fmt option version 0.6 2012-09-14 RDT Add -1 (one-pass [pdf][la]tex processing) option. version 0.5 2011-11-28 RDT Add -i (retain intermediate files) option. version 0.4 2011-04-30 RDT Allow multiple filenames (and options). Add -f (default) and -l (latex) options. version 0.3 2011-04-25 RDT Add -d (dvipdfm) and -s (stop at dvi) options. version 0.2 2011-04-21 RDT Allow basename.tex as filename. Add -p option for pdfetex processing. Add standard -v -h options. --]] local orig_print = print function usage() orig_print [[ Usage: [texlua] musixtex.lua { option | basename[.mtx | .pmx | .aspc | .tex | .ltx] } ... When no extension is given, extensions are tried in the above order until a source file is found. Preprocessing goes mtx-pmx-tex or aspc-tex, with the entry point determined by the extension. The normal route after preprocessing goes tex-dvi-ps-pdf, but shorter routes are also available, see the options. Options: -v version -h help -l latex source -p direct tex-pdf (pdftex etc) -F fmt use fmt as the TeX processor -d tex-dvi-pdf (dvipdfm) -c preprocess pmx file using pmxchords -m stop at pmx -t stop at tex/mid -s stop at dvi -g stop at ps -i retain intermediate and log files -q quiet mode (give only musixtex's own messages) -1 one-pass [pdf][la]tex processing -x run makeindex -f restore default processing Four TeX engines are available via the -l and -p options. etex default latex -l pdfetex -p pdflatex -l -p The -F option allows any engine to be named. In that case, an attempt is made to deduce implied -l and -p settings from the presence or absence of the strings `latex` and `pdf` in the name of the engine.
