CodeBeagle allows you to quickly find all occurances of a search term inside source code files. It can handle large projects with thousands of files with a very good performance. To do so it creates a full text index of the desired source files. Because it is tolerant to whitespace its search syntax works great for searching source code. The search results are displayed in a source viewer with customizable syntax highlighting. It runs without installation and leaves you in full control when to update the index. Advanced features are the support of multiple search locations, extensible context menus and custom search scripts which allow to automate sequences of searches. Although written in Python it is not required to install a Python interpreter. Version 1.2.1 is released. See CHANGES on the download page for details.
