TODO

Issues in need of work. Mostly compatibility with GNU readline, BSD libedit, and usability improvements.

Remember, the general idea is to keep this library editline small with no external dependencies, except a C library.

Add support for running in an event loop

To be able to use libeditline from within an event loop like libuEv there are few things to do:

• Refactor editinput() and readline(). Break out the active code used for set up and teardown, and the character input logic
• Add bare necessities for external callbacks so that an event loop that monitors el_infd has something to call on events
• GNU Readline has its alternate interface which we should probably implement

Example usecase of the GNU alternate interface can be found here: http://www.mcld.co.uk/blog/blog.php?274

Verify custom completion handlers

Verify for v1.14.0 that custom completion handlers still work After reverting a "fix" in v0.2.2 that made rl_complete() a function pointer we need to make sure the same functionality is still available with the new infrastructure. Which is more inspired by BSD libedit and GNU readline.

Check what's needed to run the fileman example

The BSD libedit library has imported the GNU readline "fileman" example into its tree to demonstrate the abilities of that library. This would also be quite useful for this library!

The first task is to investigate the depependencies and form TODO list items detailing what is missing and, if possible, proposals how to implement including any optional configure flags.

Other minor TODO's

• Instead of supporting multiline input, try the Emacs approach, line scrolling.
• Add support for rl_bind_key(), currently only en editline specific el_bind_key() exists.
• Make char *rl_prompt; globally visible.
• Add support for rl_set_prompt()
• Add support for --enable-utf8 to configure script
• Use strcmp(nl_langinfo(CODESET), "UTF-8") to look for utf8 capable terminal
• Implement simple UTF-8 parser according to http://www.cl.cam.ac.uk/~mgk25/unicode.html#utf-8
