c1: fatal error C1083: Cannot open source file: 'build/readline/bind.c': No such file or directory

And i can't setup it.

Is there any way to execute user code each time menu-complete displays the next completion?

E.g. in the script below, if I hit tab repeatedly, it cycles through displaying "a" and "b". I would like some of my python code to execute when it displays "a", and when it displays "b".

import rl

def complete(text):
    return ['a', 'b']

rl.completer.parse_and_bind('tab: menu-complete')
rl.completer.completer = rl.generator(complete)
raw_input()

In the readline C code I see, e.g. a call to display_matches (which itself calls rl_completion_display_matches_hook) in rl_menu_complete, but I am not entirely sure whether what I want is possible and wanted to check.

Thanks!

When a directory_completion_hook is set, readline always tilde-expands filenames. This means we lose the ability to "set expand-tilde off".

In readline before 5.2 the filename_dequoting_function is protected by a condition we are unable to satisfy, effectively disabling the hook.

I'm trying to import the rl packet using pip install in anaconda prompt(same problem in cmd) but the system can't seem to build a wheel for this package. I am using Python 3.9.12 for this system. I've found out that this problem may occur when the packet is not able to handle my python version. The documentation mentions about the usability of the packet over Python version 2.7 but it does not mention anything about the newest version it can be used in. Is there such a limitation for this package?

If it should work fine with 3.9.12, what may be the problem causing the wheel building error?

The #define has not been updated in readline 6.1. We are therefore currently blocked from implementing the new filename_rewrite_hook.

What it says. Works in 2.6.

rl 1.5.1 experiences segfaults on Linux under Python 3.1, likely related to Unicode decoding. We are investigating.

I'm trying to write a custom display matches hook, but I'm having a hard time. Basically, I can't get the redisplay(force=True) to work.

I looked at the default implementation, default_display_matches_hook, and it looks like it is doing some other stuff like clearing control-C, which I would have never even thought of. It would be nice if this function were exposed to the Python API.

Basically, all I want to do with my custom hook is to change what matches are displayed (or, more precisely, to remove a common prefix from each match, so that they aren't so long). In theory, this is as simple as creating a hook that modifies the matches list, subtracts an amount from the longest match length, calls display_match_list, and then calls redisplay(force=True), but as I noted, it doesn't work.

What exactly is the license of this code? The only reference I could find was the trove classifiers in setup.py, which list both GPL and PSF. Is it either or, or are some parts GPL and some parts PSF? Whatever it is, it would help if there were a LICENSE file that explained it.

Readline currently lacks a hook that applications could use to reliably reset their own completion variables. The logical place for such a hook would be in set_completion_defaults.

Decomposed UTF-8 causes problems with accented characters and umlauts, i.e. an "Ä" typed on the console does not have the same representation as an "Ä" occurring in a filename.
