Usage
|
|
|
|
|
============================
|
|
|
|
|
|
|
|
|
|
highlight takes one argument, the filename. highlight then reads from
|
|
|
|
|
standard input until end-of-file and writes to standard output.
|
|
|
|
|
highlight attempts to guess at the language to use for the
|
|
|
|
|
highlighting but if it fails writes plain HTML without any
|
|
|
|
|
highlighting.
|
|
|
|
|
|
|
|
|
|
Guessing the Language
|
|
|
|
|
============================
|
|
|
|
|
|
|
|
|
|
highlight attempts to guess what language to use for the syntax
|
|
|
|
|
highlighting based on a number of criteria. highlight first checks for
|
|
|
|
|
an emacs file local variable that specifies the major mode to use and
|
|
|
|
|
if it finds one maps that to the language to use for highlighting.
|
|
|
|
|
Note that it currently only checks the first line of the input. It
|
|
|
|
|
supports both the single variable form and extended form. So both '-*-
|
|
|
|
|
scheme -*-' and '-*- mode: scheme -*-' work. If it can't find an emacs
|
|
|
|
|
file local variable for the major mode it instead guesses based on the
|
|
|
|
|
file extension of the filename provided as its first argument. If it
|
|
|
|
|
still can't figure out what language it uses it will not syntax
|
|
|
|
|
highlight and instead output plain HTML.
|
|
|
|
|
|
|
|
|
|
Highlight is a generic syntax highlighter outputting HTML.
