Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

TextMate helpers

Installing

npm install first-mate

Using

ScopeSelector

{ScopeSelector} = require 'first-mate'
selector = new ScopeSelector('a | b')
selector.matches(['c']) # false
selector.matches(['a']) # true

GrammarRegistry

{GrammarRegistry} = require 'first-mate'
registry = new GrammarRegistry()
grammar = registry.loadGrammarSync('./spec/fixtures/javascript.json')
{line, tags} = grammar.tokenizeLine('var offset = 3;')
# convert compact tags representation into convenient, space-inefficient tokens
tokens = registry.decodeTokens(line, tags)
for {value, scopes} in tokens
  console.log("Token text: '#{value}' with scopes: #{scopes}")

loadGrammar(grammarPath, callback)

Asynchronously load a grammar and add it to the registry.

grammarPath - A string path to the grammar file.

callback - A function to call after the grammar is read and added to the registry. The callback receives (error, grammar) arguments.

loadGrammarSync(grammarPath)

Synchronously load a grammar and add it to the registry.

grammarPath - A string path to the grammar file.

Returns a Grammar instance.

scopeForId(id)

Translate an integer representing an open scope tag from a tags array to a scope name.

id - A negative, odd integer.

Returns a scope String.

decodeTokens(line, tags)

Convert a line and a corresponding tags array returned from Grammar::tokenizeLine into an array of token objects.

line - A String representing a line of text.

tags - An Array of integers returned from Grammar::tokenizeLine.

Returns an Array of token objects, each with a value field containing a string of the token's text and a scopes field pointing to an array of every scope name containing the token.

Grammar

tokenizeLine(line, [ruleStack], [firstLine])

Generate the tokenize for the given line of text.

line - The string text of the line.

ruleStack - An array of Rule objects that was returned from a previous call to this method.

firstLine - true to indicate that the very first line is being tokenized.

Returns an object with a tags key pointing to an array of integers encoding the scope structure of the line, a line key returning the line provided for convenience, and a ruleStack key pointing to an array of rules to pass to this method on future calls for lines proceeding the line that was just tokenized.

The tags array encodes the structure of the line as integers for efficient storage. This can be converted to a more convenient representation if storage is not an issue by passing the line string and tags array to GrammarRegistry::decodeTokens.

Otherwise, the integers can be interpreted as follows:

  • Positive integers represent tokens, with the number indicating the length of the token. All positive integers in the array should total to the length of the line passed to this method.

  • Negative integers represent scope start/stop tags. Odd integers are scope starts, and even integers are scope stops. An odd scope tag can be converted to a string via GrammarRegistry::scopeForId. If you want to convert an even scope tag, representing a scope end, add 1 to it to determine the corresponding scope start tag before calling ::scopeForId.

tokenizeLines(text)

text - The string text possibly containing newlines.

Returns an object containing a lines key, pointing to an array of tokenized lines and a tags key, pointing to an array of tags arrays described above.

Developing

  • Clone the repository
  • Run npm install
  • Run npm test to run the specs
  • Run npm run benchmark to benchmark fully tokenizing jQuery 2.0.3 and the CSS for Twitter Bootstrap 3.1.1
