aspect - I'm not a big fan of IDEs. Give me Vim and a shell and a REPL, such as Tkcon. To make Tkcon a better IDE I've developed some tools to make working between Tkcon and Vim much nicer. Hopefully others can use and improve these, and contribute their own inventions.
This toolkit allows you to start gvim from tkcon, with Tcl variables, arrays and procs, just by typing vi procname. When you save the file in gvim, it is evaluated in the running Tkcon. Suggested for use with the MiniBufExplorer vim plugin.
First, a few dependencies:
Namespace FTPD: Tcllib's ftpd package set up so that you can retrieve procs, arrays and variables from a running Tcl. It makes use of Tkcon's dump proc, which is really useful but also easily duplicated (or copied from Tkcon sources).
WARNING: this performs no authentication so it's really dangerous on any networked system. Any file uploaded to this FTP server will be executed as Tcl code in the running interp!
Call this file nsftpd.tcl.
# TODO: evaluate uploaded code in the appropriate namespace
# TODO: return ensembles for namespaces
# TODO: user authentication
