How to use

You you can install via npm install locutus and require it via require('locutus/php/filesystem/pathinfo'). You could also require the filesystem module in full so that you could access filesystem.pathinfo instead.

If you intend to target the browser, you can then use a module bundler such as Browserify, webpack or rollup.js.

ES5/ES6

This function targets ES5, but as of Locutus 2.0.2 we also support ES6 functions. Locutus transpiles to ES5 before publishing to npm.

A community effort

Not unlike Wikipedia, Locutus is an ongoing community effort. Our philosophy follows The McDonald’s Theory. This means that we don't consider it to be a bad thing that many of our functions are first iterations, which may still have their fair share of issues. We hope that these flaws will inspire others to come up with better ideas.

This way of working also means that we don't offer any production guarantees, and recommend to use Locutus inspiration and learning purposes only.

Notes

  • Inspired by actual PHP source: php5-5.2.6/ext/standard/string.c line #1559 The way the bitwise arguments are handled allows for greater flexibility & compatability. We might even standardize this code and use a similar approach for other bitwise PHP functions Locutus tries very hard to stay away from a core.js file with global dependencies, because we like that you can just take a couple of functions and be on your way. But by way we implemented this function, if you want you can still declare the PATHINFO_* yourself, and then you can use: pathinfo(‘/www/index.html’, PATHINFO_BASENAME | PATHINFO_EXTENSION); which makes it fully compliant with PHP syntax.

Examples

Please note that these examples are distilled from test cases that automatically verify our functions still work correctly. This could explain some quirky ones.
