TIA is an ncurses-based console IDE for GCC, G++, Java, Perl, PHP, BASH, BUSH, HTML, and GNAT (Ada 95). It has integrated support for CVS, SVN, and ncurses compatible mice. Features include a ddd-style console debugger, automatic spelling correction, keyword hilighting, project statistics, automatic backups, and keyboard macros. The project window controls optimization and debug settings all in one place. TIA supports make, cook, and gnatmake project builders. For large projects, each user has a separate preference file.
RANCID (Really Awesome New Cisco confIg Differ) collects a router's (or device's) configuration, including software and hardware (cards, serial numbers, etc.), and uses CVS to display differences from a previous collection. It supports Cisco routers, Juniper routers, Catalyst switches, Foundry switches, Redback NASs, and ADC EZT3 muxes. The Beta version currently includes support for Bay Networks (nortel) routers and Extreme switches. Rancid also includes a lookingglass and the device login scripts may be used to automate a number of tasks.
Meld is a visual diff and merge tool. It integrates with most version control systems. The diff viewer lets you edit files in place (diffs update dynamically), and a middle column shows detailed changes and allows merges. The margins show location of changes for easy browsing, and it also features a tabbed interface that allows you to open many diffs at once.
xRecurseDiff is a small program that can rapidly traverse entire directory trees to show the differences between different copies of the same file. It can be useful for code analysis, expecially for collaborative development. For example, it can analyze differences before a CVS/SVN submission or to resolve a conflict in concurrent editing.
