Can you retry with the current jedi dev branch?

micbou commented 8 years ago

Here's a reproducible testcase with Jedi be2a97cd36ce1b7d6f587ef122efc3433b1e8ae2:

import jedi

args = (
  '''import asyncio
async def test():
    reader, writer = await asyncio.open_connection()
    writer.
''',
  4,
  len('    writer.'),
  'example.py'
)

jedi.Script(*args).completions()

Chasing on this issue for #775

ehzawad commented 8 years ago

I swear, concurrency is always hard.. Can we take advantages from new vim 8.0 packages..? Asynchronous I/O support, channels ~

Vim can now exchange messages with other processes in the background. This makes it possible to have servers do work and send back the results to Vim. See |channel-demo| for an example, this shows communicating with a Python server.

Closely related to channels is JSON support. JSON is widely supported and can easily be used for inter-process communication, allowing for writing a server in any language. The functions to use are |json_encode()| and |json_decode()|.

This makes it possible to build very complex plugins, written in any language and running in a separate process.

Jobs ~

Vim can now start a job, communicate with it and stop it. This is very useful to run a process for completion, syntax checking, etc. Channels are used to communicate with the job. Jobs can also read from or write to a buffer or a file. See |job_start()|.

Timers ~

Also asynchronous are timers. They can fire once or repeatedly and invoke a function to do any work. For example: > let tempTimer = timer_start(4000, 'CheckTemp') This will call the CheckTemp() function four seconds (4000 milli seconds) later. See |timer_start()|.

@ehzShelter WTF are you talking about. This issue has absolutely nothing to do with either async stuff or VIM. :laughing:

ehzawad commented 8 years ago

No idea.. :D

micbou commented 7 years ago

This is fixed in the dev branch.

Thank you :)
