devenv

managing dev environments since '24

devenv is an extensible execution framework and library for authoring a simple set of high level commands - bootstrap, sync, doctor, nuke - that manage a repository's dev environment.

install

Download this and run it:

bash install-devenv.sh

user guide

devenv bootstrap

This is intended for initial setup.

devenv fetch [repository name]

Any repository on github in the form of [org]/[reponame]

Repositories are cloned to a "coderoot" directory which is specified in the global configuration.

Note: sentry and ops are currently special names which perform more complicated installations (e.g., sentry will set up both sentry and getsentry)

devenv sync

When you're inside a repository, this will bring the dev environment up to date, or create it if it doesn't exist. It runs [reporoot]/devenv/sync.py.

devenv doctor

When you're inside a repository, this diagnoses and tries to fix common issues. Checks and fixes are defined in [reporoot]/devenv/checks.

devenv nuke|uninstall (wip)

When you're inside a repository, this completely removes the dev environment.

technical overview

devenv itself lives in ~/.local/share/sentry-devenv. Inside:

• bin contains devenv itself and direnv
  • this is the only PATH entry needed for devenv
• a private python and virtualenv used exclusively by devenv

As much as possible, a repo's dev environment is self-contained within [reporoot]/.devenv.

We're relying on direnv (which bootstrap will install, globally) to add [reporoot]/.devenv/bin to PATH. Therefore a minimum viable [reporoot]/.envrc might look like:

if [ -f "${PWD}/.env" ]; then
    dotenv
fi

PATH_add "${HOME}/.local/share/sentry-devenv/bin"

if ! command -v devenv >/dev/null; then
    echo "install devenv: https://github.com/getsentry/devenv#install"
    return 1
fi

PATH_add "${PWD}/.devenv/bin"

configuration

global configuration is at ~/.config/sentry-devenv/config.ini.

repository configuration is at [reporoot]/devenv/config.ini.

develop

We use tox. The easiest way to run devenv locally is just using the tox venv's executable:

~/code/sentry $  ~/code/devenv/.tox/py311/bin/devenv sync
