Summary [PATCH] Additional commands for multi-line mode
Component All Bugs
Created attachment 16220 [details] Editline patch. This patch makes two small changes to the multi-line debugger mode, aimed at fixing some usability issues with the Swift REPL, which uses this mode exclusively. 1. A command (bound to Alt-Enter by default) to immediately execute a buffer, if possible, as opposed to breaking the current line. 2. Two commands (bound to Alt-Up/Down by default) to immediately move around in command history, without having to scroll through multiple lines with keyboard arrows. Because the REPL uses multi-line mode, it's not possible to achieve this using standard editline bindings. I don't particularly care about having specific keys bound by default, this can be done in .editrc, if suitable commands are available in the first place. Note: The comment in the line-break command states that "the completion test is allowed to change the input lines when complete", but the command itself makes no effort to redisplay them if they actually *are* changed. I've opted to do this in BufferRun, but since I'm not sure about the approach, I haven't changed any pre-existing commands. If this needs cleaning up or some follow-up explanation, do ask.
