topvhost is a curses-based display of virtual host activity on a Web server. The display is created by monitoring a collection of server log files to show update time, update count, and selected fields from the last record of each file in a top-like presentation which can be sorted by last update time, update count, or domain name. Log file format and display columns are configured using an extension of the Apache LogFormat syntax. The collection of associations between domain name and log file is specified either by direct enumeration or a file system glob() pattern in those cases where the domain name is part of the log file path. These details are saved in an INI format configuration file in the user's home directory.
HGL is a compiler/interpreter suite for developing images. It features its own simple but powerful language, Lua integration, output in various formats as well as runtime input handled by plugins, and easy integration into various environments like Web servers or graphical applications. The input is taken from a source file, which has to be compiled for quick and frequent access by the interpreter. An interpreter then runs the compiled files, takes input from custom plugins (if neccessary), and outputs its result via custom plugins.
