PHP Autocomplete is an auto-complete and combo box component for PHP developers. A working auto-complete text box requires only two lines of PHP code. It features support for multiple dependent, cascading, nested drop-downs, customization with templates and images, the ability to quickly set up fields for tagging, built-in combo box support, and loading of remote data with built-in AJAX/JSONP support.
PHP Text Diff Highlight class can find and view the difference between text strings. It takes two text strings and uses the diff algorithm to find the differences between them and return a list of changes to patch the original string to become the final string. The patch list shows what text should be added or removed to change one string into the other. The difference between the text strings may be computed in three modes: by character, by word, or by line. The class may also format the strings to view them as HTML, showing which characters are added and removed with special insertion and deletion styles. The example page works as a tool to interactively view the changes as the user changes the texts before and after the changes are applied.
Many times, developers (or even, normal users) run into an issue of searching for a resource that is inside a zip. Worse, sometime the resource is inside a zip that is itself inside another zip (i.e. a nested archive). zfind solves this problem. It is very fast and works on most common archive/compress files. It support full name search as well as regular expression search. Apart from command line usage, it also provides API support that lets you use it in your Java code as a 3rd party library.
pycdep is a tool for analyzing and visualizing C/C++ header file dependencies. A script extracts information about your code and dumps it in a Prolog database, which is used to query the dependency graph. It comes with a large number of predefined queries for finding out which files include or depend on which other files, how files depend on another file, circular dependencies, transitively implied dependencies, and design rule checks (limitations on which project can include from which other project). Visualization is supported by dumping graphs to .dot files. It also has the beginnings of a natural language interface.
CAD Scripts automates a range of CAD tasks. It includes text_to_dxf for drawing figures in DXF format by specifying co-ordinates in an input text file.It also includes support for automatically create an entire beam and column structure for FreeCAD or StadPro after entering the specifications of a building.
