A basic desk skeleton and dependency management approach for Urbit app development.

No more symlinks and dependency hell across kernel updates.

This setup uses peru to manage external dependencies. You can install it with:

• pip: pip install peru
• Homebrew: brew install peru
• The AUR if you use Arch Linux

Fork the repo and git clone it. Install peru then run ./build.sh to fetch dependencies and compile a desk.

You can then spin up a fakezod, run |new-desk %example and |mount %example in the Dojo, copy the contents of the dist folder in, |commit %example, and |install our %example. The included example app will then be running in Landscape.

The repo contains two folders and two files:

• desk: where you add your source code like agents, libraries, threads, etc. This should follow a standard desk structure (app, sur, lib, mar, etc).
• desk-dev: an optional separate folder for marks and libraries that other developers integrating with your app might need. These shared libraries are pulled in by build.sh so you don't need to keep copies in both desk and desk-dev.
• peru.yaml: dependency configuration. This is where you specify what files you need from external repos. By default it includes base-dev from urbit/urbit and landscape-dev from tloncorp/landscape.
• build.sh: A script to copy the desk and desk-dev contents into a dist folder along with the remote dependencies via peru.

You can optionally include a separate peru-dev.yaml file to pull any external developer dependencies into a dist-dev folder along with the contents of desk-dev. This can be done by running ./build build-dev.

This script brings together the files in desk and desk-dev, pulls remote dependencies, and puts them all together in a dist folder which can be committed to a ship and run.

When run without any arguments, it builds dist as described. Other arguments are:

• build: the same as without arguments, builds dist.
• build-dev: builds dist-dev from the contents of desk-dev and any remote dependencies specified in the optional peru-dev.yaml.
• clean: deletes dist and dist-dev
• help: prints these options.

You can run ./build.sh each time you change anything to rebuild dist, you don't need to run ./build.sh clean between changes.

All remote dependencies are configured in the peru.yaml file (or peru-dev.yaml for the developer stuff). You can look at the included peru.yaml to see how entries look and refer to the peru readme for detail configuration instructions.

The default peru.yaml specifies the latest commit from the master branch of base-dev and landscape-dev at the time this repo was last updated. If there's a kernel update down the line and you need to update those libraries, you can simply run peru reup to update peru.yaml to the latest commits. Then you just run ./build.sh to rebuild dist.

You can of course add additional entries in peru.yaml for other libraries you need. Everything is managed in the one place and can be kept up-to-date with a single command.

This system is intended for managing desk dependencies. If you have a separate front-end written in something like React, I'd suggest you create a ui directory and manage it there as you usually would.
