Fixed (PP) # # * fixed patchmode. TNX to "Brad M. Garcia" # # 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 ) # # * 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 for the idea. # # # # 0.8.4 - AUGUST 1999 # # * Barrie Slaymaker 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 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 patched a typo that # # made the html footer even printed if noheader was spezified. # # * new option -T=s, --title=s; suggested by Harald Fielker # # as well as Barrie Slaymaker # # . # # * significantly reduced memory usage # # * Barrie Slaymaker 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 updated the documentation. # # # # 0.8.0 - AUGUST 1999 # # * Joor Loohuis 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 # # * Joel Andersson 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 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 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 pointed me to the qq, qx, # # etc operators in perl. They should now no longer cause problems # # * Wayne Roberts # # 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 # # ) # # * if a language mode cannot be found the error message now tells # # you which lang you requested. # # * new --fallback option. This language mode is used if the # # given mode by parameter #1 is not available. This feature was # # requested by Barrie Slaymaker # # * 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.

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 language modes and outputformats 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 -o --outputformat Selects the outputformat. html is the default. To find out which outputformats are defined, issue a code2html.pl C<--modes>. =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 --template <FILE> overrides the default template for the given output format. if C<--no_header> is given too, this has no meaning. =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 REDIRECT_URL. If you want apache to automatically call code2html for all program source code files you may do this by adding these two lines to your srm.conf: AddHandler text/code .c .cc .cpp .pas .h .p Action text/code /cgi-bin/code2html?input_selector=REDIRECT_URL&foo= or something similar to this. In the AddHandle line you can choose which extensions to pass through code2html. WARNING: Do not add .pl to this line and name this script "code2html.pl". This will result in a loop. Replace /cgi-bin/code2html with the virtual location under which the file can be accessed. Note the "foo=" part. Apache appends the URL of the file to display at the end of the action part. We do not need this since we use the environment variable "REDIRECT_URL" however we do not want to get the url addes to the input_selector string. Therefore we append the "&foo=" part. Tnx to Kevin Burton <burton@relativity.yi.org> for the idea. He also states that > 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> =back =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 * file specified by C<-L> or --language_file if any =item * files specified in the evironment variable F<CODE2HTML_CONFIG>, seperated by colons =item * F<$HOME/.code2html.config> =item * F</etc/code2html.config> =item * built in default languages =back Entries in a file that is mentioned earlier in this list override rules from later files. The file structure must be valid perl code. The global variable %LANGUAGE is already defined, so you should not redeclare it using "my". It is probably the best idea to look at the definition you can see at the bottom of code2html. If your pattern includes back references like a lot patterns do in perl for example, then you have to use \2 instead of \1, \3 instead of \2 and so on. I really don't like this hack but it is a lot faster. Example: <<([^\n]*).*?^\2$ 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/ =head1 AUTHOR Peter Palfrader, computer science student at the University of Salzburg/Austria.
