jEdit is the result of numerous years of work, mainly into plug-ins. The result is an advanced text editor for programmers around the world, who prefer the advantages of free software, especially because the entire source code is available. Being open source software, one notices that the project is an achievement of an international team, so we should expect good performances from it. Another result of this collaboration on the Java written editor is the large number of macros and plug-ins, which can be downloaded using the _plug-in manager’ function. Obviously, you get auto indent and syntax highlighting for more than 200 languages. Highly customizable, it also features source code editing; a search and replace function and file management.
