NAME

       lhs2TeX - a literate Haskell to (La)TeX code translator

SYNOPSIS

       lhs2TeX [options] file

DESCRIPTION

       This  tool takes as its input a literate Haskell source file (Bird-style or LaTeX-style or
       even a combination thereof), and produces output, which, depending on the STYLE  selected,
       can  be either a LaTeX document or a stripped version of the code.  The output is produced
       on stdout.  Several directives are interpreted by  lhs2TeX  itself  and  can  be  used  to
       customize the output further.

OPTIONS

       There  are  two  sorts of options for lhs2TeX. The first selects a STYLE which governs the
       overal mode of operation for lhs2TeX. Only one style may be selected:

       --poly The poly style is an improvement of the older  math  style.  It  produces  a  LaTeX
              document,  with  the code blocks formatted using a proportional font. The output is
              highly customizable using formatting directives. Furthermore,  the  resulting  code
              respects some of the alignments made in the source file.

       --math The  math  style  is  as  poly  style,  but has less alignment capabilities. Tokens
              appearing in the source file at a special column are all  aligned  in  the  output.
              Furthermore, indentation is respected.

       --newcode
              In  the  new  code  style, everything but code blocks is stripped from the file. In
              addition, certain syntactic transformations can be  performed  on  the  code  using
              formatting  directives.  For  example,  if  the source code is annotated in certain
              positions to produce even nicer results in poly style, one can use newcode style to
              remove these annotations.

       --code In  code  style,  all comments and specification code is stripped from the file, so
              that only the code remains. Use this if you want to produce a  smaller  version  of
              your source file.

       --tt   Typewriter  style  prints  code  almost  verbatim,  using  a  monospaced  font, but
              formatting certain symbols (lambda  abstraction,  arrows  ...)  using  an  extended
              character  set.  This style is default if no style is explicitly selected, but this
              behaviour should not be relied upon.  The default style may be  changed  in  future
              versions.

       --verb Verbatim style prints code as-is, using a monospaced font. No formatting whatsoever
              is applied to the code. However, lhs2TeX does not make  use  of  a  LaTeX  verbatim
              environment,  but  rather  escapes  special TeX constructs in the translation. This
              implies that it is easier to pass the resulting TeX code to macros or use it inside
              certain environments than it would be with a native verbatim-environment.

       The  following  options  are  considered  are  also  considered as styles, but return only
       information about the program:

       -h, -?, --help
              Returns a short usage message listing all the available options.

       -V, --version
              Returns version information.

       --copying
              Displays the complete GNU General Public License.

       --warranty
              Displays the parts of the GPL than concerns warranty.

       The remaining options modify the behaviour of the program.

       -Ppath, --path=path
              Takes a (colon-separated) list path of paths that are used as search path for files
              to  be  included. If the list starts with a colon, then the list is appended to the
              current search path. If the list ends with a colon, then the list is  prepended  to
              the  current  search  path. If there is neither a colon at the beginning nor at the
              end of the list, then the list replaces the current search path.

              Environment variables can be used in the  list  of  paths,  if  enclosed  in  curly
              braces,  i.e.,  {VAR} expands to the current value of the environment variable VAR.
              If a path ends with a double slash //, then all subdirectories  of  that  path  are
              included  in  the  search  path. Note that this can significantly slow down lhs2TeX
              when looking for files.

              The built-in default search path of lhs2TeX is

                 {HOME}/lhs2TeX//
                 {HOME}/.lhs2TeX//
                 {LHS2TEX}//
                 /usr/local/share/lhs2tex//
                 /usr/local/share/lhs2TeX//
                 /usr/local/lib/lhs2tex//
                 /usr/local/lib/lhs2TeX//
                 /usr/share/lhs2tex//
                 /usr/share/lhs2TeX//
                 /usr/lib/lhs2tex//
                 /usr/lib/lhs2TeX//

       -ifile, --include=file
              Includes file before anything else. This option has the same effect as an

                 %include file

              directive at the beginning of the source file.

       -lequation, --let=equation
              Assumes equation while processing the source file. This option has the same  effect
              as a

                 %let equation

              directive at the beginning of the source file.

       -sflag, --set=flag
              Sets  flag  to  True  at the beginning of the source file. This option has the same
              effect as a

                 %let flag=True

              at the beginning of the source file.

       -uflag, --unset=flag
              Sets flag to False at the beginning of the source file. This option  has  the  same
              effect as a

                 %let flag=False

              at the beginning of the source file.
