Reasoning: I am going to add man pages support to the live ebuild, but it does
not make sense to add this to the 1.0 ebuild previously used as the base. Since
new features will likely continue to appear in the live ebuild powerline-release
script was modified to do the right thing under new circumstances.
In Python-3* it used to show the following:
Traceback (most recent call last):
File "/usr/lib/python-exec/python3.3/powerline-config", line 66, in <module>
args.function(pl, args)
AttributeError: 'Namespace' object has no attribute 'function'
now it shows
usage: powerline-config [-h] {tmux,shell} ...
powerline-config: error: too few arguments
in both python-2.7 and -3.3.
Fixes#1120.
Consider the following script:
% powerline-daemon -s powerline-test
% powerline --socket powerline-test -p/dev/null shell left
Config file not found in search paths (/dev/null): config.json
% powerline --socket powerline-test shell left
Config file not found in search paths (/dev/null): config.json
Note the problem: second call to powerline does not use offending path, but it
still emits the error “Config file not found in search paths”.
Now imports follow the following structure:
1. __future__ line: exactly one line allowed:
from __future__ import (unicode_literals, division, absolute_import, print_function)
(powerline.shell is the only exception due to problems with argparse).
2. Standard python library imports in a form `import X`.
3. Standard python library imports in a form `from X import Y`.
4. and 5. 2. and 3. for third-party (non-python and non-powerline imports).
6. 3. for powerline non-test imports.
7. and 8. 2. and 3. for powerline testing module imports.
Each list entry is separated by exactly one newline from another import. If
there is module docstring it goes between `# vim:` comment and `__future__`
import. So the structure containing all items is the following:
#!/usr/bin/env python
# vim:fileencoding=utf-8:noet
'''Powerline super module'''
import sys
from argparse import ArgumentParser
import psutil
from colormath.color_diff import delta_e_cie2000
from powerline.lib.unicode import u
import tests.vim as vim_module
from tests import TestCase
.
- Fixes lines where line with N tab indent is followed by a line with N+2 tab
indent or greater (most of such lines were already fixed in
ae92d83eae, but regex used there has one flow:
it does not catches lines where N=0 for which case first `\+` needs to be
replaced with `*`).
- Replace print(…, file=sys.stderr) with sys.stderr.write in powerline-daemon.
Assuming ascii was expected to be used when LANG=C it did not work in any case:
in this case preferred encoding is “ANSI_X3.4-1968”. Same for
`sys.getfilesystemencoding()`.
This byte is useless and can be seen in zsh output (strange that it did not
cause bugs so far, at least none I know about). It may have been needed if any
client was supposed to hold connection with daemon for a few runs, but all
current clients work in “request → output response → exit” fashion without
caring about terminating newline and definitely without preserving connection to
daemon accross runs.
Reason: there is no `file()` in Python 3.
Fix was originally presented by @kovidgoyal in [3deb69][1], but I cannot
cherry-pick this commit, because its commit message is highly undescriptive.
Fixes#1008
[1]: 3deb6988c8
It took 2/3 of do_render call according to profiler. New variant takes only 1/6.
WARNING: This commit will break all powerline installations with running daemon
because it changes communication protocol. You must kill and restart all your
powerline daemons for powerline to function properly.
Highlight @kovidgoyal
Minor changes have been applied:
- Removed copyright info and GPL 3 license since Powerline is MIT (needs
confirmation from kovidgoyal before merge)
- The `powerline-client` script is renamed to `powerline`, and calls the
daemon or `powerline-render` (the previous `powerline`) to render
a statusline
- Minor coding style corrections to match the rest of the project
- Python 3 support is removed for now due to setuptools failing with
binary scripts
Todo:
- Automatically attempt to launch powerline-daemon the first time
powerline is run if the daemon isn't already running?
- pip install -e fails with binary files (it appears that pip recodes
the powerline binary to ASCII, the compiled powerline script must be
copied manually to ~/.local/bin after pip install -e has been run)
Some notes on the commit:
1. As external_ip and email_imap_alert segments seem to be removed corresponding
segment_data keys also were removed.
2. Various files that import vim module now have the usual workaround that sets
vim local to dummy object on error.
3. Syntastic check was failing because it did not specify which highlighting
groups it uses in documentation. I made it specify them and also moved format
strings to keywords. Same for some other plugin-local themes.
4. powerline-lint script got --debug argument. Pretty useless currently though:
it only makes it output traceback for ImportError when failing to import
module to stderr.
5. Moved themes/vim/plugin/*.json to themes/vim/plugin_*.json.
6. Fixed powerline-lint that ignored problems from values.
