New Revision: 198366
URL: http://llvm.org/viewvc/llvm-project?rev=198366&view=rev
Log:
IOHandler rewrite which replaced InputReader classes with classes that properly manage stdin/out/err.
Benefits:
- curses is now supported as a IOHandler (run and hit a breakpoint and try the new "gui" command)
- editline abilities become available to any IOHandler
- the ability to edit any lines when entering multiple lines (hit up and down arrow when editing multiple lines, use ^B and ^N for history when in multi-line mode)
- separate editline history for all multi-line readers (script, commands, prompts, etc)
- readline support is now enabled for python when in multi-line mode (history, line editing, and auto completion)
- auto complete is now enabled when entering multi-line commands in "breakpoint command add" and any other commands that push IOHandlers
So please try out this branch and fix anything that needs fixing so we can get all the kinks worked out so we can switch to it and merge it back into mainline.
