CmdLine

About

CmdLine is a prompt component, which has a few extra features to fit better into a VCL environment.

Its main features over those of an ordinary prompt are :

• Dynamic line length: lines which are too long are wrapped (Word wrapping or Char wrapping)
• Independent input buffer so you can still write during input
• Input history
• Copy/paste/cut for input
• Multispace font support
• ANSI escape codes or CmdBox special escape codes (or none if you switch them off)

If you find bugs, don't work around them please, contact me, I probably can fix it in less than a day and you don't have to work around again if the next version is released.

It should work on Win32, GTK and GTK2.
