HomePage >> BasicSource >> Github:
This program is an attempt to make TCL a more productive place for programmers. You can edit the command stack using standard bash/emacs key-bindings. There is also a stack of program files being worked on and shortcuts for the common operations of editing, compiling, running and interacting with version control.
Planned new features include tab-completion on commands, file and dictionary names (how to make it quick with thousands of entries is a problem).
The help information gives a good overview of what is currently there (though aliases, program token expansion and setting the prompt are extras not mentioned).
PRINT 'Ctrl-A Start of line Ctrl-R Toggle insert mode'
PRINT 'Ctrl-B Back one char Ctrl-W Delete word'
PRINT 'Ctrl-D Delete char Ctrl-X Forward word'
PRINT 'Ctrl-E End of line Ctrl-Z Back word'
PRINT 'Ctrl-F Forward char '
PRINT 'Ctrl-G Cancel line '
PRINT 'Ctrl-I Forward word ~xxx Search for xxx'
PRINT 'Ctrl-J Delete to end .Lm,n List entry m thru n'
PRINT 'Ctrl-M Accept line .Rn Restore entry n, edit'
PRINT 'Ctrl-N Next line .Dm,n Delete entry m thru n'
PRINT 'Ctrl-P Previous line Q Quit back to TCL'
PRINT
PRINT '/ List the program stack // List the stack with cvs status'
PRINT '[[/Nx]] Add a New program,'
PRINT '[[/Ex]] Edit the x`th program [[/WW]] Edit the program list'
PRINT '[[/Wx]] VI the x`th program [[/S]] Sort the program stack'
PRINT '[[/Bx]] Compile the x`th program [[/BR]] Compile and run'
PRINT '[[/CI]] Checkin a program to cvs [[/D]] Show diff with cvs version'
