* Allow yapf to lint individual files
* Add tip for using yapf
* Update doc
* Update script to autoformat changed py files
The new default is for the script to only updated changed files to encourage
using it as a pre-push hook. Travis still checks all since it's not that big an
increase to runtime.
* Exclude formatting thirdparty/autogen py files
* Symlink .travis -> scripts
Hidden directories may get glossed over otherwise.
* .travis -> scripts in docs
They are symlinks to the same thing, but `scripts` is more dev-friendly, while
`.travis` is really only for Travis CI.
* Document different yapf format functions
Most devs will only need `format_changed`, and this is run by default.
`format_changed` should be fast enough in most cases to work as a pre-commit
hook.
* Speed up yapf by only formatting changed files
* Update docs
1. Mention how yapf can be used a pre-commit hook
2. rm `bash`, script is executable
* Update yapf.sh
* Update development.rst
* Update yapf.sh
* Use bash arrays for correct argument splitting
Playing fast and loose with whitespace in bash is a terrible idea.
* Only format non-excluded by default
* Check changes against master
Normally, the remote is called `origin`, but naming it explicit
* Adding missing directory to `format_all`
* Cleanup YAPF code
Remove unused function and move around code to make clearer and adding lines
give cleaner diffs.
* Ensure correct files are autoformatted
* Fix cmd line arg splitting
Each arg has to be in its own set of quotes.
* Diff against mergebase
TIL there's a clean syntax for doing that, but it's too clever to belong in a
shell script.
We use `mapfile -t` to ensure no problems down the line with weird filenames.
* Use pep8 style
The original style file is actually just pep8 style, but with everything
spelled out. It's easier to use the `based_on_style` feature. Any overrides are
clearer that way.
* Improve yapf script
1. Do formatting in parallel
2. Lint RLlib
3. Use .style.yapf file
* Pull out expressions into variables
* Don't format rllib
* Don't allow splits in dicts
* Apply yapf
* Disallow single line if-statements
* Use arithmetic comparison
* Simplify checking for changed files
* Pull out expr into var
