NAME
coq-tex - Process Coq phrases embedded in LaTeX files
SYNOPSIS
coq-tex [ -o output-file ] [ -n line-width ] [ -image coq-image ] [ -w
] [ -v ] [ -sl ] [ -hrule ] [ -small ] input-file ...
DESCRIPTION
The coq-tex filter extracts Coq phrases embedded in LaTeX files,
evaluates them, and insert the outcome of the evaluation after each
phrase.
Three LaTeX environments are provided to include Coq code in the input
files:
coq_example
The phrases between \begin{coq_example} and \end{coq_example}
are evaluated and copied into the output file. Each phrase is
followed by the response of the toplevel loop.
coq_example*
The phrases between \begin{coq_example*} and \end{coq_example*}
are evaluated and copied into the output file. The responses of
the toplevel loop are discarded.
coq_eval
The phrases between \begin{coq_eval} and \end{coq_eval} are
silently evaluated. They are not copied into the output file,
and the responses of the toplevel loop are discarded.
The resulting LaTeX code is stored in the file file.v.tex if the input
file has a name of the form file.tex, otherwise the name of the output
file is the name of the input file with `.v.tex' appended.
The files produced by coq-tex can be directly processed by LaTeX. Both
the Coq phrases and the toplevel output are typeset in typewriter font.
OPTIONS
-o output-file
Specify the name of a file where the LaTeX output is to be
stored. A dash `-' causes the LaTeX output to be printed on
standard output.
-n line-width
Set the line width. The default is 72 characters. The responses
of the toplevel loop are folded if they are longer than the line
width. No folding is performed on the Coq input text.
-image coq-image
Cause the file coq-image to be executed to evaluate the Coq
phrases. By default, this is the command coqtop without
specifying any path which is used to evaluate the Coq phrases.
-w Cause lines to be folded on a space character whenever possible,
avoiding word cuts in the output. By default, folding occurs at
the line width, regardless of word cuts.
-v Verbose mode. Prints the Coq answers on the standard output.
Useful to detect errors in Coq phrases.
-sl Slanted mode. The Coq answers are written in a slanted font.
-hrule Horizontal lines mode. The Coq parts are written between two
horizontal lines.
-small Small font mode. The Coq parts are written in a smaller font.
CAVEATS
The \begin... and \end... phrases must sit on a line by themselves,
with no characters before the backslash or after the closing brace.
Each Coq phrase must be terminated by `.' at the end of a line. Blank
space is accepted between `.' and the newline, but any other character
will cause coq-tex to ignore the end of the phrase, resulting in an
incorrect shuffling of the responses into the phrases. (The responses
``lag behind''.)
