ls-lint

# The Basics

# Creating configuration

Your ls-lint configuration must be located in a .ls-lint.yml file in your project root directory and provides two options:

.ls-lint.yml 
ls: 
    ... 

ignore: 
    ...

ls defines the structure of your project directories with all their rules for your extensions, sub-extensions and directories while ignore can ignore some of these files and directories completely

# Extensions & sub-extensions

You might ask yourself - what the hell are sub-extensions? ls-lint describes file extensions like .js or .html as extensions while .d.ts, .umd.js or .local.build.js file extensions are described as sub-extensions.

# Global configuration

A global configuration for your project is optional but could be the best solution. Imagine you want to define that all of your .js, .ts and .d.ts project files must be named in the kebab-case style but you want to ignore your .git and node_modules directories - this can be solved like this:

.ls-lint.yml 
ls:
    .js: kebab-case
    .ts: kebab-case
    .d.ts: kebab-case

ignore: 
    - .git 
    - node_modules

Pretty easy, isn`t it?

Rules Rules Rules

Don`t worry, there are many more rules to use: All rules

# Linting directory names

You also can define rules for directories by the .dir definition

ls:
    packages/src:
        .dir: kebab-case # applies for the current directory and all their subdirectories
        .js: kebab-case

# Using multiple rules

Sometimes you need to accept multiple rules for a single file extension - This can be easily solved by the | operator:

.ls-lint.yml 
ls:
    .js: kebab-case | camelCase | PascalCase

# Different rules for different directories

Pretty often there are different rules for different directories or you just want to define rules only for some specific directories:

.ls-lint.yml 
ls:
    .js: kebab-case

    models:
        .js: PascalCase

    src/templates:
        .js: snake_case

Keep in mind

Directory configurations like models or src/templates will override all rules for the current directory and all their subdirectories

# Using directory patterns

# The glob pattern

The glob pattern * or ** can be used for all of your ls and ignore directory configurations:

.ls-lint.yml 
ls:
    packages/*/src: # matches any sequence of non-path-separators
        .js: kebab-case

    packages/**/templates: # matches any sequence of characters, including path separators
        .html: kebab-case

ignore:
    - '**/*.png'
    - bazel-*

# The alternative pattern

The alternative pattern can be used for all of your ls and ignore directory configurations:

.ls-lint.yml 
ls:
    packages/*/{src,tests}: # matches a sequence of characters if one of the comma-separated alternatives matches
        .js: kebab-case

ignore:
    - '**/{a,b}/*.js'
