Power Form Validation is class which helps a programmer to validate form inputs just in few lines of code. This class can help control whether a field is empty, whether a component is selected, whether the values of two components are the same, whether a text entry value consists only of letters, whether a value was changed from a given value, and whether a value is longer than or shorter than or equal to a given value. The class can also control how many components are not selected or how many of them have no value entered. Email addresses can be validated with regular expressions.
Stratego/XT is a development environment for creating stand-alone transformation systems. It combines Stratego, a language for implementing transformations based on the paradigm of programmable rewriting strategies, with XT, a collection of reusable components and tools for the development of transformation systems. In general, Stratego/XT is intended for the analysis, manipulation, and generation of programs, though its features make it useful for transforming any structured documents. In practice, it has been used to build many types of transformation systems including compilers, interpreters, static analyzers, domain-specific optimizers, code generators, source code refactorers, documentation generators, and document transformers.
PHP Link Directory is link indexing software with many features, extensions, customizations, and flexibility of design. It uses mod_rewrite to display friendly URLs, and has the option to display the Google pagerank of links. Email templates can be set up to make it easy to do link exchanges, as well as send notifications about link acceptance.
The Off-the-Record (OTR) Messaging proxy is a multi- platform proxy that allows you to have private conversations using the AIM client of your choice. It provides encryption, which prevents someone who intercepts your instant messages from reading them, authentication, which ensures that the correspondent is who you think it is, and perfect forward secrecy, which ensures that no previous conversation is compromised if you lose control of your private keys.
Tidybot traverses one or more source directories, and runs all HTML files it finds through the TidyLib checker, collecting all warnings and errors it encounters and presenting them nicely in an XHTML report. It is possible to specify files/directories to exclude from the checks, warnings/errors to suppress in the generated report, and "key:value" options to pass directly to the underlying TidyLib engine. The generated report can use a custom CSS stylesheet. Tidybot has both a command-line interface and a GUI. Tidybot is not an XML/XHTML validator.
"jscpp" is an ANSI C preprocessor and language parser that can analyze and instrument C code. Currently, its most prominent application is to add tracing to existing C programs simply by recompiling and linking it with the "jscc" compiler frontend. The standard tracing shows when a function is entered or left along with the parameters passed or return values. It is also possible to trace each source line and watch read/write access to simple variables. Tracing is achieved by instrumenting the source code before calling the system compiler. The program is modular and can be easily extended to other kinds of source code modifications.
