# HISTORY #
# #
# 0.8.7d - OCTOBER 1997 #
# * langmode is not case insensitive #
# #
# 0.8.7c - OCTOBER 1997 #
# * line numbers AGAIN :/ (this time everything schould work :) #
# #
# 0.8.7b - OCTOBER 1997 #
# * line numbers AGAIN :/ #
# #
# 0.8.7a - OCTOBER 1997 #
# * declared result in putout, so code2html runs with use strict #
# * patching works with stdin to stdout too. #
# #
# 0.8.7 - OCTOBER 1997 #
# * the newslines where missing with lin[ke]numbers. Fixed (PP) #
# * fixed patchmode. TNX to "Brad M. Garcia" <bgarcia@fore.com> #
# for the bug report (PP) #
# #
# 0.8.6 - OCTOBER 1999 #
# * changed some perl patterns, faster & smaller html (PP) #
# * replaced (abc|Abc|ABC) style patterns with (?i)abc (PP) #
# * changed config file layout; using a data structure now (PP) #
# * speed #
# o create_snippets tweaking (BS) #
# o Pod::Text not used but required (BS) #
# o _new_ _improved_ (great words, eh?) perl patterns (BS) #
# * checkTab in again (PP) #
# #
# 0.8.5 - AUGUST 1999 #
# * fixed linenumbers. #
# * html patching now also has an outputfile. #
# (Daniel Winkelmann <winkelma@chemie.fu-berlin.de>) #
# * html patching failed when refering to external files. this is #
# fixed now. TNX to Daniel Winkelmann for the bug report #
# * code2html in CGI mode now encodes the output as bz2/gz/Z if #
# the program is on the server and the format is accepted by #
# the client (HTTP_ACCEPT_ENCODING). #
# TNX to Matty <mattpratt@yahoo.com> for the idea. #
# #
# 0.8.4 - AUGUST 1999 #
# * Barrie Slaymaker <barries@slaysys.com> sent a different #
# approach for finding & inserting tags. the hidechar way is no #
# longer needed. It is quite fast and needs not that much #
# memory. #
# #
# 0.8.3 - AUGUST 1999 #
# * removed 'use HTML::Entities' line. it HTML::Entities was not #
# used anyway. #
# #
# 0.8.2 - AUGUST 1999 #
# * John Douglas Rowell <me@jdrowell.com> submitted some perl #
# tweaks to correctly parse <<"-x-"; and =begin/=end blocks. #
# * anchors are not used any more when no line numbers are wanted. #
# * John Interrante <interran@crd.ge.com> patched a typo that #
# made the html footer even printed if noheader was spezified. #
# * new option -T=s, --title=s; suggested by Harald Fielker #
# <fielker@informatik.fh-augsburg.de> as well as Barrie Slaymaker #
# <barries@slaysys.com>. #
# * significantly reduced memory usage #
# * Barrie Slaymaker <barries@slaysys.com> sent a patch to speed up #
# insert_tags. I already had a not that bad version some time ago #
# but somehow it got lost. Anyway Barrie's way is _a_lot_ faster #
# than mine. #
# #
# 0.8.1 - AUGUST 1999 #
# * Joor Loohuis <joor@casema.net> updated the documentation. #
# #
# 0.8.0 - AUGUST 1999 #
# * Joor Loohuis <joor@casema.net> converted the long help text to #
# pod (plain old documentation, see perlpod(1)). The major #
# advantage is that the documentation can now simply be #
# converted to html, man, LaTeX or plain text, by using one of #
# the filters from the standard Perl POD module. #
# * Joor Loohuis also contributed an example of automatic #
# language recognition. I adapted it and it is now part of #
# code2html. As a result the syntax has changed. langmode is no #
# longer obligatory but optional with -l <langmode> #
# * Joel Andersson <joel@post.netlink.se> sent me the patterns for #
# awl, m4, groff. #
# * perl tweaks; again :/ #
# * regular expressions in config files are now checked for #
# correctness. code2html fails gracefully if a regex is wrong. #
# #
# 0.7.1 - August 1999 #
# * corrected (hopefully) a gotcha in the perl patterns (again...) #
# * added one item to the changelog of 0.7.0 #
# * --replace_tabs no longer replaces every tab with the given #
# amount of spaces but instead it now replaces it with the right #
# number to go to the next tabstop. the parameter given to #
# replace_tabs gives the width of tabstops. #
# TNX to T. Jahn <tjahn@crosswinds.net> for providing an example #
# of how to do this in one of his programs. If I had known it #
# was that easy I'ld have done it earlier :) #
# #
# 0.7.0 - August 1999 #
# * No longer need for that stupid fatal_error sub. I now use perl's #
# handlers for __DIE__ and __WARN__ #
# * complete rewrite of the option and parameter fetching sub. I #
# now use Getopt::Long. TNX to Barrie for the pointer. As a #
# the number for --replace_tabs / -t is no longer optional. #
# * Added HTML patching: code2html now also allows you to have #
# inline source code in an html file. It can then take this html #
# file and insert the syntax highlighted code. #
# Look in the help. It's very usefull ( at least for me ) #
# * the CGI mode got a forth way to pass the input file. If the #
# input_selector parameter is set to REDIRECT_URL the file is #
# taken from ENV{'DOCUMENT_ROOT'}.$ENV{'REDIRECT_URL'}. #
# Kevin Burton <burton@relativity.yi.org> suggested this so that #
# it is possible to configure Apache with an action directive #
# to automatically print java files syntax highlighted. #
# #
# 0.6.6 - July 1999 #
# * added sql - it is still very poor since I don't know all the #
# keywords etc. If you know, tell me. #
# * Martynov Andrew <root@tn.energo.ru> pointed me to the qq, qx, #
# etc operators in perl. They should now no longer cause problems #
# * Wayne Roberts <wroberts1@cx983858-b.orng1.occa.home.com> #
# reported a problem with C strings like "\\". It should be fixed #
# too. #
# * I changed the operator with which the default language base #
# is assigned to a variable, so there's no need for \\\\\\\\\\ #
# quotes anymore :) #
# #
# 0.6.5 - June 1999 #
# * tweaking Perl regular expressions (TNX to Barrie Slaymaker #
# <rbs@telerama.com>) #
# * if a language mode cannot be found the error message now tells #
# you which lang you requested. #
# * new --fallback <lang> option. This language mode is used if the #
# given mode by parameter #1 is not available. This feature was #
# requested by Barrie Slaymaker <rbs@telerama.com> #
# * changed 'is called as CGI' heuristics. #
# #
# 0.6.4 - May 1999 #
# * the name attribute in the line numbers was wrong. there should #
# be no # in it. TNX to <stifle33@hotmail.com> #
# * linking to line numbers now works from the command line too #
# #
# 0.6.3 - May 1999 #
# * fixed C character constant regex. TNX to Jesse #
# <jesse@lmscadsi.com> #
# * line numbers now can link to themselves #
# * line numbers now have a constant width #
# #
# 0.6.2 - May 1999 #
# * fixed something in HTML lang #
# #
# 0.6.1 - May 1999 #
# * added 'plain' language mode #
# * cgi support improoved. should now also handle #
# enctype="multipart/form-data" forms #
# #
# 0.6.0 - May 1999 #
# * fixed Substitution loop at ./code2html.pl (5.2) line 627 #
# * changed string regular expressions: \" is no longer a problem #
# * default locations for the language files have changed: #
# first all the files listed in the enviroment variable #
# CODE2HTML_CONFIG (seperated by colons (:)) will be checked, #
# then, if HOME set, $HOME/.code2html.config and finally #
# /etc/code2html.config #
# TNX to Eric Brandwine <ebrandwi@UU.NET> for the hint. #
# * new: --no_header does not print the <html><head>... stuff #
# * new: --content_type prints Content-Type: text/html; #
# * C/C++: in preprocessor lines: strings are highlighted now #
# * -n now also names the lines with <a name="line<nr>">..</a> #
# * script may now be run as a CGI script. see the CGI section #
# in the help #
# * get_config_file was rewritten because it was _ugly_ #
# #
# 0.5.2 - May 1999 #
# * fixed Makefile dependency line bug. (a * in regexp instead a +) #
# #
# 0.5.1 - May 1999 #
# * clarified copyright questions on regular expressions #
# * changed -dumb_default_lang to -dump_default_lang :) #
# #
# 0.5.0 - Apr 1999 #
# * changed find_all_matches__create_taglist__insert_placeholders #
# so that it works around a bug in earlier perl versions, in which #
# pos() is not set if the return value of m//g is not used. #
# * changed a regex in get_config_file #
# #
# 0.4.1 - Mar 1999 #
# * changed JavaScript regexps slightly #
# * changed find_all_matches_.. slightly #
# #
# 0.4.0 - Mar 1999 #
# * script no longer needs $' and $` thus beeing faster. $& is still #
# needed #
# * regexps for perl changed slightly #
# * find_all_matches has been completly rewritten. verify is no #
# longer needed. taglist is built while searching. #
# May take a bit longer now, but otherwhise a bug could not have #
# been fixed. #
# * changed (fixed?) start of language_def_block pos evaluation #
# #
# 0.3.3 - Feb 1999 #
# * fixed STDIN/STDOUT parameters when passed a - the scrpit though #
# options would follow and didn't tread this as a handle for STDIN #
# * added -V as shortcut to --version #
# #
# 0.3.2 - Feb 1999 #
# * removed -T from 1st line so activePerl will run the script #
# without any modifications #
# * changed perl string regexps. run now faster and better #
# (and run at all under win) #
# * added --replace_tabs #
# #
# 0.3.1 - Feb 1999 #
# * fixed language files bug (<space>lang_mode<space> no longer #
# starts langmode) #
# * fixed empty html tag bug when reading lang specs #
# * added languages: Makefile, Java, JavaScript, Perl #
# * added --modes #
# #
# 0.3.0 - Feb 1999 #

code2html - Converts a program source code to HTML
=head1 SYNOPSIS
=over 4
=item (1)
code2html [options] [input_file [output_file]]
=item (2)
code2html C<-p> [file]
=item (3)
code2html (as a CGI script: see CGI section below)
=back
=head1 DESCRIPTION
code2html is a perlscript which converts a program source
code to syntax highlighted HTML.
=over 4
=item (1) OPTIONS
=over 4
=item input_file
Is the file which contains the program source code
to be formatted. If not specified or a minus (-) is
given, the code will be read from STDIN.
=item output_file
Is the file to write the formatted code to. If not
specified or a minus (-) is given, the code will be
written to STDOUT.
=item -l, --language_mode
Specify the set of regular expressions to use.
These have to be defined in a language file
(see FILES below). To find out which language modes
are defined, issue a code2html.pl C<--modes>.
This input is treated case-insensitive.
If not given, some heuristics will be used to
determine the file language.
=item -v, --verbose
Prints progress information to STDERR. You will not
need this.
=item -n, --linenumbers
Print out the source code with line numbers.
=item -N, --linknumbers
Print out the source code with line numbers.
The linenumbers will link to themselves, which
makes it easy to send links to lines.
=item -t, --replace_tabs <TABSTOP WIDTH>
Replace each occurence of a <TAB> character with
the right amount of spaces to get to the next
TABSTOP.
can be changed by an optional argument.
=item -L, --language_file <FILE>
Specify an alternate languages file to take the
regular expressions from (see FILES below).
=item -m, --modes
Print all defined modes currently defined to STDOUT
and exit succesfully. Also prints modes from a
given language_file if applicable.
=item --fallback <LANG>
If the language mode givin with the first parameter
(language_mode) cannot be found then use this mode.
Usefull when code2html is called from a script to
ensure output is created: C<--fallback plain>
=item --dump_default_lang
Write default language file to STDOUT and exit
succesfully.
=item -h, -? --help
Print this text and exit succesfully.
=item -V --version
Print the program version and exit succesfully.
=item -c --content_type
Prints "Content-Type: text/html\n\n" prior to the
html file. Usefull if the script is ivoked as a
cgi script.
=item -H --no_header
do not print the <html>, <head>, <body>, <pre>
stuff. Usefull if this script is only a part in
a bigger program.
=item -T --title
Set the title of the produced HTML file.
=back
=item (2) code2html.pl -p [infile [outfile]]
code2html now also allows you to have inline source code
in an html file. It can then take this html file and
insert the syntax highlighted code.
If no file is given, code2html reads from STDIN and
writes to STDOUT. If just one file is given it replaces
this file with the output.
To use this feature, just insert a like like this into
your html file:
<!-- code2html add [options] <file> -->
the syntax highlighted file will be inserted at this
position enclosed in <pre> tags.
All options that can be given on the command line
like C<--linenumbers> etc. work. C<--help> and C<--version>
etc. work too however it is not very
intelligent to use them :). C<--content_type> is ignored.
You may also write the program's source code directly
in the html file with the following syntax:
<!-- code2html add [options]
<your program source code here>
-->
It is usually a good idea to at least give the C<-l> option
to specify the language.
This is a very new feature, so if you have problems or
questions, please let me know. An example can be found
at my homepage: http://www.cosy.sbg.ac.at/~ppalfrad
=item (3) CGI
If the the script is used as a CGI script
(GATEWAY_INTERFACE environment set and no command line
arguments given) code2html reads the arguments either from
the query string or from stdin. (methods POST and GET).
--content_type is switched on automatically and the output
always goes to STDOUT.
The following parameters/options are accepted:
=over 4
=item language_mode - optional
'c', 'cc', 'pas', etc.
if not given, some heuristics are used to find out the
language.
=item fallback - optional
'plain', 'c', etc.
if language_mode cannot be found, use this one
=item input_selector - optional
either 'file', 'cgi_input1', 'cgi_input2', or
'REDIRECT_URL'
default: file
=item filename
file to read from if input_selector is 'file'
=item cgi_input1
the source code to syntax highlight
for example from a <textarea> or from a upload.
see input_selector
=item cgi_input2
the source code to syntax highlight
for example from a <textarea> or from a upload.
see input_selector
=item line_numbers - optional
'yes', 'no' or 'link'
default: no
=item replace_tabs - optional
if 0 then tabs are not replaced, if larger then each
tab is replaced by that many spaces.
default: 0
=item title - optional
Set's the title of the HTML file.
=item no_encoding - optional
By default code2html tries to encode the output as either
bz2/gz/Z if the client supports this (HTTP_ACCEPT_ENCODING)
and the needed program is available on the server.
You may need to modify @CGI_ENCODING in the script to match
your program locations.
If no_encoding is defined and true code2html does not try to
encode the output.
=back
Why two cgi_inputs you may ask: This is to allow your
users to choose vie a <form> interface whether they want
to insert their file into a <textarea> or user a <browse>
button to select their file. See the example on my home-
page.
Note that by default it is possbile for your users to read
all the files the httpd can read (if you don't run a cgi-
wrapper or something like this . You may disallow file
reading via cgi with setting FILES_DISALLOWED_IN_CGI to 1
at the top of the script.
The input selector REDIRECT_URL needs a special
explaination. The file name is formed from the two
enviroment variables DOCUMENT_ROOT and REDIRECET_URL.
Kevin Burton <burton@relativity.yi.org> will tell you
what you need this for:
> So I had a problem where I wanted all my Java files
> automatically converted to html and displayed. But I
> didn't want to write any crazy web interface for
> code2html.
> So what I did was this.
>
> Configured Apache with an "Action" directive in srm.conf
> like this:
>
> Action text/java
> /cgi-bin/code2html?language_mode=java&input_selector=REDIRECT_URL
>
> Works great!
>
> It is more powerfull if you use it in an Apache
> <Directory> tag
>
> <Directory /source>
>
> #with your Action tag here... this way you can
> #still have regular .java files on your server.
>
> </Directory>

=head1 EXAMPLE
assuming code2html.pl is in the current directory, you may
type
code2html.pl -l perl code2html.pl code2html.html
to convert the script into a html file.
=head1 FILES
=over 4
=item *

=back
Entries in a file that is mentioned earlier in this list
override rules from later files.
The file structure must be valid perl code.
The global variable %LANGUAGE is already defined, so you
should not redeclare it using "my".
It is probably the best idea to look at the definition
you can see at the bottom of code2html.
If your pattern includes back references like a lot patterns
do in perl for example, then you have to use \2 instead of \1
\3 instead of \2 and so on. I really don't like this hack but
it is a lot faster.
Example:
<<([^\n]*).*?^\2$
In this example the perl << stuff is matched, i.e. everything
from a << until a line that consists of exactly the same
string as behind the << was. The \2 references the matched
chars in the parentenses.
If you ever write languages files yourself, I'ld be happy
if you could send be them, so I put them on my homepage
with full credits of course.
Before you do so you might also have a look at my site to
check wheter someone has written the file for your
language already.
=head1 NOTES
The language recognition mechanism relies on specific patterns within
the name and content of a file that is to be highlighted, such as
extensions and shebangs (#!). This means that if an unnamed or
incomplete file is to be filtered, typical for patch and CGI modes,
the language name should be specified using the C<-l> command line
parameter.
=head1 BUGS
Please report bugs to ppalfrad@cosy.sbg.ac.at. This
program is still in beta so you might find some. Also have
a look at my web-site, perhaps a new version is available
already: http://www.cosy.sbg.ac.at/~ppalfrad/
