Free regexp software for linux

The Castor project has been developed out of need: the need to get stuff done and the need to write useful code.
It has been designed and coded over many cups of Dunkin Donuts Hazlenut coffee, Starbucks Latte, and tall no-whip White Mochas, as proof that coffee beans do come in handy.
Castor includes software, such as Xerces, Jakarta ORO, and Jakarta Regexp, developed by the Apache Software Foundation. Castor also includes JUnit testing framework
Main features:
- Castor XML: Java object model to and from XML (XML databinding)
- Generate source code from an XML Schema
- Default introspection or mapping file for existing object models
- Castor JDO: Java object persistence to RDBMS Castor JDO is not the same-as or compatible with Suns JDO. We have a different approach to handling data object to RDBMS mappings.
- XML-based mapping file to specify bindings for existing object models
- Support for schema-less Java to XML binding
- In memory caching and write-at-commit reduces JDBC operations
- Two phase commit transactions, object rollback and deadlock detection
- OQL query mapping to SQL queries
- EJB container managed persistence provider for OpenEJB
- Ability to create base mapping from existing Java classes
- Ability to create an XML Schema from an XML input document
Enhancements:
- Fixed problem with TransactionContext.getObjectEntry(Object) that was introduced as a result of adding support for lazy loading 1:1 relations.
- Added F.A.Q. entry describing compatibility problems between various releases of mySQL 4.1.x and its JDBC drivers.
- Reverted various DOCTYPE definitions in src/tests/jdo to use DTDs.
- Fixed issue with GeneralizedFieldHandler not able to handle collections. Collections are now automatically iterated over during getValue() calls and each item in the collection is passed into the convertUponGet method. To retain the old behavior simply add a call to #setCollectionIteration with a value of false in the constructor of your GeneralizedFieldHandler. The behavior for setter methods is not changed since only one item at a time is passed into the setter already.
- Fixed whitespace processing bug, where a was actually getting appended to the end of a string value if the parser was calling the #characters method again with only whitespace following a previous call to #characters method where valid content existed.
- Fixed recent issue where ElementDecl#getType() method was always returning null for element references.

KLMCL is a graphical MUD client for KDE with support for aliases, regexp triggers, spellup spells management, key bindings More detailed information can be found under DocManager: Project Documentation.
Enhancements:
- Colour codes shouldnt break between buffers now.
- ANSI sequences besides colours are gracefully ignored instead of thrown away.
- Screen selections wont disappear.
- Random minor cleanups.

Randomplay is a command-line based shuffle music player that remembers songs between sessions.
Randomplay plays your music collection (or execute any arbitrary commands on any arbitrary filetypes) in random order, remembering songs played across sessions.
Randomplay also has many features to make command-line music playing more convenient, including recursive regexp searching for tracks and the ability to specify a certain number of tracks, bytes, or minutes to play.
Randomplay will also generate a list of music files to be loaded onto a portable music player device. It includes a random weighting feature, so your favorite songs are more likely to come up in the random shuffle.
Randomplay is a convenient tool for the user who does everything in an xterm window or console and is constantly devising complex find/grep/sed command lines to play just the right set of songs.
Following are some example invocations of randomplay to give a general sense of its flexibility; see the manpage for more complete information:
Play all ogg files in dir1 and dir2 under your home directory, and dir3 under the base directory specified in ~/.randomplayrc, which have not been played for 15 days in random order with 5 seconds between songs:
randomplay --days=15 --pause=5 --player ogg=ogg123 ~/dir1 ~/dir2 =dir3
Play all ogg, wav, and mp3 files under the current directory (or base directory, if specified in .randomplayrc file) which have not been played for 10 days in alphabetical order, switch the skip to next song keystroke to G or g and quit to q or c:
randomplay --norandom --key next=Gg --key quit=qc
Play all files under the current directory with the strings "frisell" and "bill" in the filename, in any order, (saves having to hunt down a file in a hierarchy), ignore whether the file has been played recently, but stop playing after 15 minutes:
randomplay --regexp frisell bill -0 --maxtime=15m
Display 100M worth of music files, randomly sorted, without recording the history of tracks, using the default music directory (or the current directory if not specified):
randomplay --maxsize=100M --noremember --names-only
Play the last 10 songs played over again:
randomplay --last=10
Play songs test.ogg, test2.ogg, test3.ogg, and all files in musicdir in random order without weighting preferred songs:
randomplay --noweight test.ogg test2.ogg test3.ogg musicdir
Copy 128M of songs into a Neuros Audio Player, using positron:
positron add randomplay --names-only --maxsize=128M
Pick a random jpeg or png file that has not been displayed in the last week from the images directory and display it with ImageMagick display command:
randomplay --player jpg=display --player gif=display --days 7 ~/images
Enhancements:
- New keystrokes for pausing and displaying all available keystrokes while playing were added.
- UTF-8 output for MP3 tags can now be disabled.
- A bug that prevented randomplay from working with sox was fixed.
- The documentation was improved.

The Revisionist is a tool for extracting and indexing hidden metadata (such as deleted or modified text) from large collections of MS Word files.
It can operate whole Web sites or SMB or NFS directories. The Revisionist project is handy for pen-testing, or it can be used just to spot embarrassing secrets.
My primary goal is to provide pen-testers and content administrators with a handy tool to detect hidden data in all documents available at a specific location (be it a locally mounted network share, a HTTP site, or whatnot), and easily review it all.
Right now, the tool only detects and indexes deleted text in documents with "change tracking" enabled, and can also index usernames and hardware addresses embedded in documents (to facilitate external assessment of company structure); future versions should be able to recover other goodies, too.
Usage:
To run the tool against a local directory, a mounted SMB or NFS directory, or such, simply issue the following command (after doing make, that is):
./therev @/path/to/directory
After the tool completes, you should be able to view master.html in current directory using your favourite browser (Lynx, Netscape, etc). Cached copies of documents would be placed in subdirectories named document.XXXXXX, where X is a random digit; hence, it is recommended to run the tool in a separate directory.
Note that you may also instruct the tool to look for specific substring and only choose those documents that contain it (strict checking, no regexp available):
./therev linux @/path/to/directory
To run the program against a specific site or top-level domain, do the following:
./therev site.com
Note that com, gov, gov.pl, www.microsoft.com are all a valid site name. The first parameter works similar to the previous case:
./therev homeland security gov
As a special bonus, when running the script against multilinguinal sites, you might want to specify a third parameter - desired language (using a two-letter code: en, pl, etc). NOTE: DO NOT USE LANGUAGE QUALIFIER UNLESS NECESSARY:
./therev linux microsoft.com en
The HTTP search mode uses Google.com to locate all matching Word documents on a specific site. For a document to be found, it must be indexable (that is, not excluded in robots.txt) and be in the first 1000 of results for a specific site. If there are more than 1000 documents at some website, consider sub-searches with keywords.
Enhancements:
- This release was fixed to work with the new Google page layout.
- Some other minor fixes were made.

Visual REGEXP project can easily design and debug regular expressions by providing a graphical visualization of the expression and its matches on a sample of your choice.
Version restrictions:
- some regexp can consume a lot of CPU time. This seems to be caused by the use of -all, -inline and -indices flags together.
- when a subexpression is not matched (empty match), the last character of the previous match are coloured. This is due to a problem in Tcl (bug submitted to Scriptics).
Enhancements:
- new version done by Martin Lemburg. Many thanks, Martin.
- it is now a tcl 8.5a4 starpack
- GUI layout changed to be based on a paned window
- GUI code looks different, to be more ergonomic
- the informational labels (replacements & matches) are now sunken
- there are now additional the "first" and "last" navigation buttons
- there is a new option to navigate through matches or matches and submatches
- the displayed count of matches is changed to display the current and the count of matches used for navigation (probably changes, if the new navigation option is changed)
- the replace widget is disabled on startup
- the tcl console is added to the help menu
- the key bindings inside the regexp text widget changed a bit to allow for expanded regexp (-expanded or (?x)) to contain tabs and newlines. Tabs are created with Control-Tab and newlines with Control-Return. Additional with Control-C|V|X (not c|v|x) it is possible to use the clipboard like with Control|Shift-Insert, Shift-Delete.
