CCTree is a Vim 7 plugin that displays hierarchical call-trees for functions or files using a cscope database. The functionality is similar to that offered by other IDEs and source-analysis applications, like Kscope, Source Navigator, and Eclipse. CCTree features a symbol dependency tree analyzer for C using a cscope database. It has basic support for functions and macros, and extended support for global variables, macros, enums, and typedefs.
Rho is a small, very powerful console-based POSIX text editor and mini-IDE with Bash/Emacs key bindings. A configuration file allows the user to create macros using not only any internal function but anything available to a shell command. Keyboard macros (Ctl-Alt-A through Z) can be sourced into the editor for each kind of task, the next sourcing overwriting the last. Rho also allows an unlimited number of templates (sh, awk, python, etc.) to be injected into executable buffers which trap stdout and stderr.
Exchanges is a Bash CGI script for collaborative creation of manuscripts. It allows new entries to be injected between existing entries. Owners of entries may edit or delete them. Anyone may comment on them. By default, one views the entire document. Exchanges are directory-based, with a single CGI handling multiple writing projects.
XOSDVolume is a graphical sound volume level indicator. It monitors the audio mixer device, and whenever there is a change, it displays the current volume level on an OSD-type window for a short time. It supports real transparency by using the X Shape extension, without the need of an X compositing manager.
