ConTEXT is a text editor for Microsoft Windows. It has built-in syntax highlighters for C, C++, Pascal, Delphi, FORTRAN, 80x86 assembler, Java, JavaScript, Visual Basic, Perl, CGI, HTML, SQL, Python, PHP, Tcl, Tk and its own syntax highlighter definition language. Other features are code templates and the ability to work with several document windows using the Multiple Document Interface. ConTEXT can integrate compilers to compile source code from within the editor, and run external tools to manipulate loaded files (e.g. Pretty Printer). The output of such external programs, e.g. error messages, can be captured for further use. Incremental search and basic regular expressions are supported for searching and replacing. ConTEXT is available in many languages.
