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][gnu] which we should
|
|
probably implement
|
|
|
|
Example usecase of the GNU alternate interface can be found here:

|
|
|
|
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
