crusca-cli

crusca-cli

crusca-cli is the Node client for crusca, a drop-in replacement for xgettext to extract translation strings from Javascript files.

xgettext falls short on ES6 template strings, that are incidentally the best and more modern way to create translation strings in JS clients.

---

From this approach that implies an String.prototype.format hack in place

  const str1 = t('Organisation {0} is now {1} #orgStatus').format(orgName, orgStatus);
  const str2 = t('Fill in the {0} #academy').format('<strong>{0}</strong>').format(this.state.title);

To this purely native approach

  const str1 = t`Organisation ${orgName} is now ${orgStatus} #orgStatus`;
  const str2 = t`Fill in the ${this.state.title} #academy`;

---

In it's very simplest form, this is it

# from this
find app/assets -type f -iname '*.js' | xargs xgettext --no-wrap --default-domain=javascripts --keyword=t --from-code=UTF-8 -o $pot_file

# to this
node_modules/.bin/crusca-cli -i app/assets -o $pot_file

Usage

crusca-cli -i path/to/files -o output.pot [-e -g -c -v]

Examples

Scanning the directory /Users/domo/projects/myPrj to look for .js files and extract strings using all the default parameters.

crusca-cli -i /Users/domo/projects/myPrj -o myPrj.pot

---

Parse a single file and extract strings from it.
Note: any --ignore or --ext option will be ignored when parsing a single file.

crusca-cli -i file.js -o strings.pot

Installation

You can either install crusca-cli as a global package or local to your project.

globally

npm install -g crusca-cli

You can then use it anywhere by simply calling crusca-cli

locally

npm install --save-dev crusca-cli

crusca-cli will then be available in node_modules/.bin/crusca-cli.
You can either use it from an NPM-script simply by calling it or you can reference to it's path to access it from anywhere, like a shell script.

E.g.

"scripts": {
  "extract": "crusca-cli -i ./src -o strings.pot -e .js -e .jsx"
}

or

#!/bin/bash

prj_dir=./src
output=strings.pot

node_modules/.bin/crusca-cli -i $prj_dir -o $output

Config File

crusca-cli can be configured using a config file which takes the same options listed in the options section, except --config obviously.

{
  "ignore": [
    "bower_components",
    "node_modules"
  ],
  "extensions": ["js", "jsx"]
}

Options

Bold options are required

Options	Default	Description
-i, --in	--	File or directory to search for translation strings
-o, --out	--	Output file that will contain the extracted strings
-e, --ext	.js	Whitelist file extensions you want to parse (adds leading dot, if missing). Multiple entries are allowed
-g, --ignore	[]	Blacklist file or directories you don't want to scan. Support minimatch glob expressions. Multiple entries are allowed
-c, --config	./cruscarc	Custom config path
-v, --verbose	false	Enable chatty version
-q, --quite	false	Completely silent on success
-h, --help	--	Show help

Configurations Priority

It is important to note that there is a priority when supplying options

config_file (default or custom with -c)
├── cli_arguments
├───── default_arguments

For example
crusca-cli -i some/folder -o strings.pot -c ./conf -e js -e jsx -g test

Where ./conf is

{
  "ext": "js"
}

Will only consider .js files, because the config has higher priority, while still ignoring the folder test, since it has not been overridden in the config file

TODOs

• get the same params of .cruscarc from command line
• add crusca options to crusca-cli config file and command line
• implement --ignore and --ext as cli options
• implement --verbose, --in, --out in cruscarc
• put defaults in a separate place
• output JSON to console (--json, -j)
• add tests
