c2html
======
Where to get c2html?
--------------------
The homepage of c2html is
http://user.cs.tu-berlin.de/~schintke/x2html/index.html
You can get c2html also from the metalab server:
ftp://metalab.unc.edu/pub/Linux/apps/www/converters/
What is c2html?
---------------
The c2html program is a syntax highlighter for C source code that
produces a highlighted html file as output. The output can be read by
any graphical WWW-Browser. If the browser understands the tags to
change font colors (as Netscape does) the output will look like
highlighted by emacs. Otherwise it will not look so nice, but
readability is increased too.
Who uses c2html?
----------------
Everyone who provides sources in the web.
How do I use c2html?
--------------------
This is rather simple. If you start the program without any parameters
it will read the source from stdin and prints the output to stdout.
If you invoke c2html with filenames on the command line it will
process every given file in sequence and will store the output in new
files. The names of the new files are built by appending ".html" to
the corresponding input filename.
How do I convert my C sources on demand only?
---------------------------------------------
You need a webserver to do this. The webserver must be configured to
INVOKE c2html as a CGI program to handle all *.c and *.h files. If
your webserver is apache you can achieve this by adding lines
AddType text/x-c .c .h
Action text/x-c /cgi-bin/c2html
to configuration file "http.conf". The c2html program expects the
pathname of it's input file in environment variable PATH_TRANSLATED.
CGI mode works by checking for environment variables GATEWAY_INTERFACE
and PATH_TRANSLATED. If both are set a HTTP header line
Content-Type: text/html
and meta tags with the files last modification date and the program
that generated the html file are written to the html header.
If you want to call the converter with default parameters like -n you
have to write a wrapper script like the following (Notice that you
have to 'chmod +x' the script file):
file c2html_wrap in the cgi-bin directory of your webserver:
--
#! /bin/sh
./c2html -n
--
Then you let apache call the wrapper script with the following entry:
Action text/x-c /cgi-bin/c2html_wrap
Since your sources are converted on-the-fly to HTML you don't need any
webspace for your html-ized files. Furthermore you don't have to
bother about keeping your published html-ized sources up to date. :)
If one wants to save the html-ized source for compiling it is best to
use the "Text" format when saving from the browser.
How can I save bandwidth using c2html as a CGI?
-----------------------------------------------
If c2html has been compiled with -DCOMPRESSION=1 it will compress it's
HTML output with gzip if your browser supports it. This will save
bandwidth but add additional load to your webserver machine. If you
are connected to a server on 'localhost', c2html will not compress
it's output by gzip. Larger values for COMPRESSION than 1 are not
recommended because it adds more CPU load to the server without saving
much bandwidth.
