NAME

       qsource-highlight - A Qt4 front-end for GNU Source-Highlight.

SYNOPSIS

       qsource-highlight

DESCRIPTION

       With  qsource-highlight  you  can  highlight  your  code on the fly, and have the highlighted output in a
       format supported by source-highlight (e.g. HTML, LaTeX, Texinfo, etc.).  You can then save the  formatted
       output to a file, or copy and paste it.

       A preview of the highlighted output is available for some output formats (HTML and XHTML).

       Main Window

       The  main  window  of  qsource-highlight  permits opening a file to highlight, to tweak some highlighting
       options, and to see the output of highlighting.

       The language definition file is automatically selected according to the input file extension, but you can
       change it manually by using the corresponding combo box. In particular you have three combo boxes:

       the combo box for the input language definition (e.g., C, C++, Java, etc.); this refers to the .lang file
       names used by Source-Highlight; they should be quite intuitive.

       the combo box for the output format (e.g., HTML, LaTeX, etc.); this refers to the .outlang file names
       used by Source-Highlight; they should be quite intuitive (e.g., htmltable.outlang generates HTML output
       into an html table).

       the combo box for the highlighting style (e.g., colors, and formats of the elements of the language);
       these elements refer to Source-Highlight .style file names and to .css files.

       All the files named in these combo boxes refer to files  shipped  with  Source-highlight,  and  they  are
       searched  for in the Source-highlight corresponding installation path. In case the combo boxes are empty,
       then the path where source-highlight searches for these files is not correct: you  should  configure  the
       correct path for source-highlight using the settings dialog (Source-Highlight Settings).

       The  icons  corresponding  to  actions  available in QSource-Highlight should be quite standard and their
       meaning should be immediate; from left to right they are:

       Open File: this opens a file as an input file (whose contents can be edited, but, most of all,
       highlighted).

       Open Style: this opens a style file to be used for highlighting. Note that this is useful when you have
       your own style file that is not part of source-highlight style files (thus it would not be selectable in
       the corresponding combo box).

       Save current input file.

       Save the current output file (i.e., the output of highlighting).

       Save the current style file (see also Style Settings).

       Highlights the current input file using the selected language definition file, the selected output format
       and the selected style.

       As previous, but highlight only the currently selected lines of the input file.

       Options

       On the main window there is also an "Options" pane which can be used to tweak source-highlight formatting
       options. We refer to the documentation of source-highlight for further  details;  here  we  only  briefly
       summarize the main options:

       Document options

       entire document: generates a complete document with the highlighted output; the semantics of "entire"
       strictly depends on the formatting output (e.g., for HTML it means that html header will be used, for
       LaTeX that an output that can be compiled in isolation will be produced, etc.).

       header & footer: you can specify header and footer files that will be used in the formatted output
       (required the "entire document" option).

       tabs to spaces: tabular characters in the input are converted in the output into the corresponding number
       of spaces.

       Line options

       Line numbers: generates line numbers in the highlighted output (you may want to try the sub options and
       see what happens to the line numbers).

       Context lines: if only selected lines are highlighted, this option permits to specify the number of
       "surrounding context" lines to be put in the output as well (without highlighting though).

       Settings - Style Settings

       You  can  use  the highlighting style dialog to customize the current highlighting style. This provides a
       way to customize the output style of each language element recognized by the current language  definition
       file (e.g., keywords, comments, symbols, etc.). You can also save the currently customized style.

       Settings - Source-Highlight Settings

       Source-highlight  library  uses  a  path (called data dir) to search for language definition file, output
       format definition files, style files, etc.  This  path  must  be  set  correctly  otherwise  highlighting
       features  will  not  work.  In  a  standard  installation  this path should already be set appropriately.
       However, if you use a non standard installation of source-highlight, this path might not be set correctly
       (a symptom, as said in the previous section, is when the combo boxes are simply empty). You can set  this
       path using the Settings -> Source-highlight Settings menu. This will bring a dialog where you can set the
       path  (or  choose  it  with  the browse button); notice that the dialog also checks whether the currently
       selected path is a valid path for source-highlight (it should  contain  at  least  a  lang.map  file  and
       associated .lang, .outlang and .style files).
