Replaces calls to a function __ with replacements from a dictionary.
An example. Given a test.js like so:
console.log(__("HELLOWORLDKEY"));
And a dictionary.tsv like so:
"Key" "English"
"HELLOWORLDKEY" "Hello, World"
Running replace-i18n.js -l en -d dictionary.tsv < test.js > test.en.js gives an output file like so:
console.log("Hello, World");
