Converts a .sty file (LaTeX package) to .dtx format (documented LaTeX source), by surrounding macro definitions with ’macro’ and ’macrocode’ environments. The macro name is automatically inserted as an argument to the ’macro’ environemnt. Code lines outside macro definitions are wrapped only in ’macrocode’ environments. Empty lines are removed. The script is not thought to be fool proof and 100% accurate but rather as a good start to convert undocumented style files to .dtx files.
perl sty2dtx.pl infile [infile ...] outfile
or
perl sty2dtx.pl < file.sty > file.dtx
The following macro definitions are detected when they are at the start of a line (can be prefixed by \global, \long, \protected and/or \outer):
\def \edef \gdef
\xdef
\newcommand{\name} \newcommand*{\name}
\newcommand\name \newcommand*\name
\renewcommand{\name} \renewcommand*{\name}
\renewcommand\name \renewcommand*\name
\providecommand{\name} \providecommand*{\name}
\providecommand\name \providecommand*\name
\@namedef{\name} \@namedef\name
The following environment definitions are detected when they are at the start of a line:
\newenvironment{name} \renewenvironemnt{name} \provideenvironment{name}
The macro and environment definition must either end at the same line or with a ’"}"’ on its own on a line.
sty2dtx [<options>] [−−<VAR>=<VALUE> ...] [−−] [<infile(s)>] [<outfile>]
|
• |
can be ’"−"’ for STDIN or STDOUT, which is the default if no files are given | ||
|
• |
multiple input files are merged to one output file |
Variables can be defined using
−−<VAR>=<VALUE>
or
−−<VAR> <VALUE>
and will be used for substitutions in the template file.
Common variables:
author, email,
maintainer, year (for copyright),
version, date, description (of package/class),
type (either 'package' default or 'class'),
filebase (automatically set from output or input file
name),
−h
Print
this help text
−H
Print
extended help
−V
Print
version and copyright
−v
Be
verbose
−o output Use given file
as output
−O
Overwrite
already existing output file(s)
−B
Use
basename of single input file for output file
−I
Also
create .ins (install) file
−c
Only
use code section (like v1.0)
−r
Remove
existing ’macro’, ’macrocode’, etc.
environments.
−R
Do
not remove existing ’macro’,
’macrocode’, etc.
environments.
−i ins-file Create .ins file with
given name
−t template Use this file as template
instead of the default one
−T template Use this file as template
for the .ins file
−e file
Export default .dtx
template to file and exit
−E file
Export default .ins
template to file and exit
−D
Use
current date as file date
−F file Read
more options and variables from file.
−N
Do
not read default config file; must be the first option
A default config file either named ’sty2dtx.cfg’ or ’.sty2dtx.cfg’ is searched in the current directory, the users home directory and the directory of this script, in this order. The first one found is loaded. If none is found the ’texmf’ tree is searched for a ’sty2dtx.cfg’ config file. As with −F files the config file should contain one option or variable per line. Lines starting with ’"%"’ or ’"#"’ are ignored.
Produce ’file.dtx’ from ’file.sty’:
sty2dtx.pl < file.sty > file.dtx
or
sty2dtx.pl file.sty file.dtx
or
sty2dtx.pl −B file.sty
Produce ’file.dtx’ and ’file.ins’ from ’file.sty’:
sty2dtx.pl −I file.sty file.dtx
or
sty2dtx.pl file.sty −i file.sty file.dtx
or
sty2dtx.pl −IB file.sty
Set custom variable values:
sty2dtx.pl −−author Me −−email [email protected] mypkg.sty mypkg.dtx
Produce DTX file for a class:
sty2dtx.pl −−type class mycls.sty mycls.dtx
