# A nix flake that sets up a complete Synapse development environment. Dependencies
|
||||
# for the SyTest (https://github.com/matrix-org/sytest) and Complement
|
||||
# (https://github.com/matrix-org/complement) Matrix homeserver test suites are also
|
||||
# installed automatically.
|
||||
#
|
||||
# You must have already installed nix (https://nixos.org) on your system to use this.
|
||||
# nix can be installed on Linux or MacOS; NixOS is not required. Windows is not
|
||||
# directly supported, but nix can be installed inside of WSL2 or even Docker
|
||||
# containers. Please refer to https://nixos.org/download for details.
|
||||
#
|
||||
# You must also enable support for flakes in Nix. See the following for how to
|
||||
# do so permanently: https://nixos.wiki/wiki/Flakes#Enable_flakes
|
||||
#
|
||||
# Usage:
|
||||
#
|
||||
# With nix installed, navigate to the directory containing this flake and run
|
||||
# `nix develop --impure`. The `--impure` is necessary in order to store state
|
||||
# locally from "services", such as PostgreSQL and Redis.
|
||||
#
|
||||
# You should now be dropped into a new shell with all programs and dependencies
|
||||
# availabile to you!
|
||||
#
|
||||
# You can start up pre-configured, local PostgreSQL and Redis instances by
|
||||
# running: `devenv up`. To stop them, use Ctrl-C.
|
||||
#
|
||||
# A PostgreSQL database called 'synapse' will be set up for you, along with
|
||||
# a PostgreSQL user named 'synapse_user'.
|
||||
# The 'host' can be found by running `echo $PGHOST` with the development
|
||||
# shell activated. Use these values to configure your Synapse to connect
|
||||
# to the local PostgreSQL database. You do not need to specify a password.
|
||||
# https://matrix-org.github.io/synapse/latest/postgres
|
||||
#
|
||||
# All state (the venv, postgres and redis data and config) are stored in
|
||||
# .devenv/state. Deleting a file from here and then re-entering the shell
|
||||
# will recreate these files from scratch.
|
||||
#
|
||||
# You can exit the development shell by typing `exit`, or using Ctrl-D.
|
||||
#
|
||||
# If you would like this development environment to activate automatically
|
||||
# upon entering this directory in your terminal, first install `direnv`
|
||||
# (https://direnv.net/). Then run `echo 'use flake . --impure' >> .envrc` at
|
||||
# the root of the Synapse repo. Finally, run `direnv allow .` to allow the
|
||||
# contents of '.envrc' to run every time you enter this directory. Voilà!
