Supported Runtimes

Write Scripts in Bash, Python, JavaScript and TypeScript

You can write scripts in all of the most popular scripting languages. Bash, Python, JavaScript and TypeScript are supported out-of-the-box.

Choose a runtime from the dropdown in the Editor tab.

In order for your Fig script to be executed, the runtime must be installed and on your PATH. If the runtime binary is not installed, you will be prompted to install it.


Requires: bash

ObjectNaming conventionExample

Parameters passed to bash scripts are unquoted by default. Wrap inputs in single quotes to prevent them from being modified by the shell.

git commit -m '{{message}}'


Requires: python3

ObjectNaming conventionExample

When writing a script in Python, you can import libraries normally:

For instance, to manipulate PDFs using python, you can use the PyPDF2 library.

Run pip install PyPDF2 or pip3 install PyPDF2 to install the package, and then it will be accessible in your script.

import PyPDF2

pdf = open(fig.params.pdfpath, 'rb')

reader = PyPDF2.PdfFileReader(pdf)

# get first page of PDF
page = pdfReader.getPage(0)

# get the text from the first page
texts = page.extractText()

# print the text


Requires: node or deno

ObjectNaming conventionExample

When writing a script in JavaScript, you can import libraries using ES6 syntax:

import fs from "node:fs"

let contents = fs.readFileSync(fig.inputs.filepath)

You can also import node packages that are installed globally.

For example, to use the cowsay package, install it with the -g flag:

npm install -g cowsay
import * as cowsay from "cowsay"

let output = cowsay.say({ text: fig.inputs.message });


Requires: deno
