coq-tex

COQ-TEX(1)						      General Commands Manual							COQ-TEX(1)

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 egin{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 egin{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 egin{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 out-
       put 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 out-
	      put.

       -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  egin...  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 charac-
       ter  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''.)
