JomeLib

JomeLib is the opiniated part of Jome. It gives access to a lot of utilities to help you get started.

It is a list of functions and constants.

It is like a playlist. It gives you something to get started quickly. Over time, you will probably make your own playlist.

Built-Ins

The language includes a lot of built-in functions and constants. They start with a hashtag (#) symbol.

For the complete list of utils: see the utils page.

// A constant
let x = #PI/2
let e = #e // Euler's number

// A function
let angle = #sin(x)
let logarithmic = #log10(2)
#log("The angle is:", angle) // #log is a shorthand for console.log

By addind a dot before the hashtag, you can call the function with the preceding token as an argument.

// A function acting upon a variable
let keys = obj.#keys // same as #keys(obj) or Object.keys(obj)

Utils include most things global in javascript and useful utils like in underscore.js.

Math: #PI, #sin, #cos, #tan, ..., #rand? console: #log, ... process: #argv, #env, #cwd... underscore.js: #map, #reduce, ...

For functions that have a sync and async version, use the exclamation mark after to use the sync version.

#write! 'Some content', to: './somefile.txt', overwrite: true

Piping

You can write the input to a function call to the left by using the operators :., |> or .#

.# refer to built-in functions which are always available. The other two will use local functions or global ones defined in the file config.jome.
