Polite linter for git prepush hooks

Everybody likes git prepush hooks – they prevent us from pushing invalid code to repository.

But there are always few problems:
* hooks run on current INDEX, so if your commits are pure, but INDEX is dirty and contains some lint errors, it won't be pushed.
* or vice versa, you have committed files with mistakes, fixed them after and would easily push them if prepush runs on current INDEX
* linters run on whole project, no matter that you have committed one file

Polite linter analyzes your log and runs linter only on files which are _committed_ since last push, linting their _HEAD_ version.

All linting runs in memory, not using or affecting local files at all

How to use

Polite linter for now supports eslint and tslint linters(contributions for another linters are welcome!)

npm i polite-linter --save-dev

If you are using husky, just add to your package.json

"prepush": "polite-tslint --rules=path_to_custom_rules --config=path_to_tslint_config

or

"prepush": "polite-eslint"

--
If you are using pure git hooks, use in your pre-push

polite-tslint --rules=path_to_custom_rules --config=path_to_tslint_config

Options

$3

If you are using _tslint_, there are two options you can provide:
* --rules – path to your custom rules directory(if you are using one)
* --config – path to your basic config file. By default ./tslint.json is used

$3

_Eslint_ for now does not support any flags – it will find .eslintrc by itself and use it to lint your files
