Tree Editor TrEd 

Author: Petr Pajas, 2001

Description

TrEd is a graphical editor and viewer of tree structures. Internally TrEd works with so called FS-format developed by M. Kren (the same file format is used also in editor Graph).

If configured properly, TrEd may also open and save files in different formats, provided that a tool for conversion to/from FS-format is given. Moreover, if nsgmls SGML parser is installed on the system, CSTS SGML files may be opened in TrEd directly.

TrEd may be extended by user-defined macros written in Perl. There are many pre-defined functions for treating of tree structures at macro-programmer's disposal. Macros may invoked by user-defined keyboard shortcuts or using menu items.

There is also a non-graphical (off-line) variant of TrEd called btred - "Batch-mode Tree Editor" - which allows user to run macros on trees without having to enter the graphical interface and a command-line tool based on the TrEd's libraries with facilities for automated printing trees or exporting them to other graphical formats.
