Vint is a Vim script Language Lint. The goal to reach for Vint is:

• Highly extensible
• Highly customizable
• High performance

But now, Vint is under development. We hope you develop a policy to help us.

Quick start

You can install with pip <https://pip.pypa.io/en/latest/>__.

::

$ pip install vim-vint

You can use Vint with vim-syntastic/syntastic <https://github.com/vim-syntastic/syntastic>__::

let g:syntastic_vim_checkers = ['vint']

Configure

Vint will read config files on the following priority order:

• User config <#user-config>__:

• e.g. ~/.vintrc.yaml (the filename can be .vintrc.yml or .vintrc)

• Project config <#project-config>__:

• e.g. path/to/proj/.vintrc.yaml (the filename can be .vintrc.yml or .vintrc)

• Command line config <#command-line-config>__:

• e.g. $ vint --error, $ vint --max-violations 10

• Comment config <#comment-config>__ (highest priority):

• e.g. " vint: -ProhibitAbbreviationOption +ProhibitSetNoCompatible

You can see all options on Wiki <https://github.com/Kuniwak/vint/wiki/Config>__.

The default configuration is defined in default_config.yaml <vint/asset/default_config.yaml>_.

User config

You can configure global Vint config by ``~/.vintrc.yaml`` as following:

.. code:: yaml

    cmdargs:
      # Checking more strictly
      severity: style_problem

      # Enable coloring
      color: true

      # Enable Neovim syntax
      env:
        neovim: true

    policies:
      # Disable a violation
      ProhibitSomethingEvil:
        enabled: false

      # Enable a violation
      ProhibitSomethingBad:
        enabled: true

You can see all policy names on `Vint linting policy
summary <https://github.com/Kuniwak/vint/wiki/Vint-linting-policy-summary>`__.

Project config

You can configure project local Vint config by .vintrc.yaml as following:

.. code:: yaml

cmdargs:
  # Checking more strictly
  severity: style_problem

  # Enable coloring
  color: true

  # Enable Neovim syntax
  env:
    neovim: true

policies:
  # Disable a violation
  ProhibitSomethingEvil:
    enabled: false

  # Enable a violation
  ProhibitSomethingBad:
    enabled: true

You can see all policy names on Vint linting policy summary <https://github.com/Kuniwak/vint/wiki/Vint-linting-policy-summary>__.

Command line config

You can configure linting severity, max errors, ... as following:

::

    $ vint --color --style ~/.vimrc

And you can see all available options by using `--help`:

::

    $ vint --help
    usage: vint [-h] [-v] [-V] [-e] [-w] [-s] [-m MAX_VIOLATIONS] [-c]
                [--no-color] [-j] [-t] [--enable-neovim] [-f FORMAT]
                [--stdin-display-name STDIN_DISPLAY_NAME]
                [files [files ...]]

    Lint Vim script

    optional arguments:
      -h, --help            show this help message and exit
      -v, --version         show program's version number and exit
      -V, --verbose         output verbose message
      -e, --error           report only errors
      -w, --warning         report errors and warnings
      -s, --style-problem   report errors, warnings and style problems
      -m MAX_VIOLATIONS, --max-violations MAX_VIOLATIONS
                            limit max violations count
      -c, --color           colorize output when possible
      --no-color            do not colorize output
      -j, --json            output json style
      -t, --stat            output statistic info
      --enable-neovim       enable Neovim syntax
      -f FORMAT, --format FORMAT
                            set output format
      --stdin-display-name STDIN_DISPLAY_NAME
                            specify a file path that is used for reporting when
                            linting standard inputs

Comment config
~~~~~~~~~~~~~~

You can enable/disable linting policies by a comment as following:

.. code:: vim

    " vint: -ProhibitAbbreviationOption

    let s:save_cpo = &cpo
    set cpo&vim

    " vint: +ProhibitAbbreviationOption

    " do something...

    " vint: -ProhibitAbbreviationOption

    let &cpo = s:save_cpo
    unlet s:save_cpo

And you can use line config comments. It can enable/disable linting policies in only one line by the postfix comment:

.. code:: vim

    " vint: next-line -ProhibitUnusedVariable
    let s:foobar = 'x'
    echo s:{'foo' . 'bar'}

This syntax is: `" vint: [next-line] [+-]<PolicyName> [+-]<PolicyName> ...`.
