@msiebuhr/angular-enforcer v0.2.0

angular-enforcer

Command line script to lint style rules in Angular templates and automatically correct them. Can be used on any HTML file, not just Angular templates.

Corrects missing end-tags

from:

<div>
    <div>
        <span>
            <img>

to:

<div>
    <div>
        <span>
            <img>
        </span>
    </div>
</div>

Corrects inconsistent text case

from:

<B>BOLD TEXT</B>

to:

<b>
    BOLD TEXT
</b>

Installation

npm install angular-enforcer -g

Usage

On a specific file

enforce [file path] [options] where file path is a path to a file to enforce

On STDIN

cat [file path] | enforce -i Simply pipe some file into the enforce command

On a glob

enforce -g [glob string] [options] where glob string(https://github.com/isaacs/node-glob) is a string to search for files using Ex: enforce -g src/folder/**/*.tpl

On every html file in this folder and all child folders

enforce -g [options] This will run the angular-enforcer program on every html file in this folder and all child folders

From node

You can also import angular-enforcer and use it as you want.

import ngEnforcer from 'angular-enforcer';
import 'fs';
const file = fs.readFileSync('file');
const output = ngEnforcer(file, {
    lineLength: 150
});

The ngEnforce function takes a string of HTML and options and returns formatted HTML. Linting is not available when using this method.

Options

Formatting options

• --tab-length: the number of spaces to consider a tab. Default is 4.
• --spaces: If true (default), converts spaces to tabs, using the specified tab length. Otherwise it does the reverse, converting tabs to spaces.
• --line-length: max line length. Default is 100.
• --closing-slash: if true, convert to . Default is false.
• --short-tags: comma separated list of additional tags that have no associated end tag
• --expr-padding: add a space before and after angular expressions (and a space after the "::" in one-time binded expressions). Default is true.
• --attr-newline: If an html start tag is over the specified line-length, start each attribute on it's own line, indenting by one. Default is true.
• --empty-tag-same-line: Empty DOM nodes will end their tags on the same line if it's within the max line length.
• --short-text-nodes: DOM nodes with just text that can fit on one line will do so. Default is true. If this is false, the text nodes will be indented.
• `--attr-obj-indent: Indent JS objects inside attributes, ex: inside ng-class. True by default.
• --double-quotes: If true, use double quotes for attributes, otherwise use single quotes.
• --reorder-attrs: If true, alphabetize HTML attributes in each tag
• --block-spacing: If true, add an empty line in between each HTML block
• --text-wrap: If true, break long text nodes so that indentation + length of text <= line-length. Defaults to true.
• --wrap-ignored-tags: comma separated list of tags to ignore long text nodes inside
• --remove-comments: if true, enforcer will remove all HTML comments

CLI-only options

• --config -c: path to the formatting config file. Default is .enforcer.json
• --save -S: report and correct all problems, overwriting all affected files
• --glob -g: Glob strings to look for files
• --stdin -i: read from STDIN instead of giving a file path.
• --verbose -v: more verbose reporting, including locations of problems.
• --quite -q: silences all output, even when using --diff or --verbose.
• --diff -d: print a colored diff of the changes

.enforcer.json JSON file

All options can be specified in an .enforcer.json file. All options are in camelCase.

{
     "tabLength": 2,
     "lineLength": 120
}

Option load order:

1. command line options
2. .enforcer.json file in current directory (if it exists)
3. .enforcer.json file in home directory (if it exists)

TODO

• specify file extension to look for
• add a -s option to save files, disable by default
• add linting features
  • lint when using HTML tags in an invalid way
• add formatter options
  • tab length
  • option to start new attributes lined up with the first attribute:

    <input class="foobar"
           bar="baz">

  • max line length
  • Angular expression spaces
  • attribute spacing
  • attribute value formatting
  • self-closing tags
  • new line between code blocks
  • encoding of characters
  • better parsing of angular attributes: https://github.com/peerigon/angular-expressions
  • order attributes
    • build in angular directive's preferred order
• unit tests
