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 🙏

gettext-extractor

License: MIT GitHub all releases GitHub issues GitHub commit activity [![Tests Status][status-tests-badge]][status-tests-link]

A flexible and powerful Gettext message extractor with support for JavaScript, TypeScript, JSX and HTML, and others via regular expressions.

This is a fork of the original program written by Lukas Geiter. As per some posts in the issues of the original repository, Lukas was in the middle of a full rewrite of the program, which has not materialized yet. However, a useful patch to use regex was contributed but it was never merged. Hence the fork.

This program works by running your files through a parser and then uses the AST (Abstract Syntax Tree) to find and extract translatable strings from your source code. All extracted strings can then be saved as .pot file to act as template for translation files.

Unlike many of the alternatives, this library is highly configurable and is designed to work with most existing setups.

For the full documentation check out the Github Wiki of the original project.

Installation

Note: This package requires Node.js version 6 or higher.

Yarn

yarn add gettext-extractor

NPM

npm install gettext-extractor

Getting Started

Let's start with a code example:

const { GettextExtractor, JsExtractors, HtmlExtractors, RegexExtractors } = require('gettext-extractor');

let extractor = new GettextExtractor();

extractor
    .createJsParser([
        JsExtractors.callExpression('getText', {
            arguments: {
                text: 0,
                context: 1
            }
        }),
        JsExtractors.callExpression('getPlural', {
            arguments: {
                text: 1,
                textPlural: 2,
                context: 3
            }
        })
    ])
    .parseFilesGlob('./src/**/*.@(ts|js|tsx|jsx)');

extractor
    .createHtmlParser([
        HtmlExtractors.elementContent('translate, [translate]')
    ])
    .parseFilesGlob('./src/**/*.html');

extractor
    .createRegexParser([
        RegexExtractors.addCondition({
            regex: /\_translate\((.*)\)/i,
            text: 1
        })
    ])
    .parseFilesGlob('./src/**/*.tmpl');

extractor.savePotFile('./messages.pot');

extractor.printStats();
