dev Command

The dev command is a helper for using docker compose.

For example, you can run a sql script via

dev sqlcmd -i ./data/funding_submission_lines.sql

assuming the file is located at /db/data/funding_submission_lines.sql

Note that the dev command uses the db service, and so only has access to folders under the top-level db directory.

Set up dev command

The dev command vastly simplifies development using docker compose. It only requires ruby; however, direnv and asdf will make it easier to use.

It's simply a wrapper around docker compose with the ability to quickly add custom helpers.

All commands are just strings joined together, so it's easy to add new commmands. dev prints out each command that it runs, so that you can run the command manually to debug it, or just so you learn some docker compose syntax as you go.

1. (optional) Install asdf as seen in https://asdf-vm.com/guide/getting-started.html.

   e.g. for Linux

   apt install curl git
   
   git clone https://github.com/asdf-vm/asdf.git ~/.asdf --branch v0.12.0
   
   echo '
   # asdf
   . "$HOME/.asdf/asdf.sh"
   . "$HOME/.asdf/completions/asdf.bash"
   ' >> ~/.bashrc
   

2. Install ruby via asdf as seen here https://github.com/asdf-vm/asdf-ruby, or using whatever custom Ruby install method works for your platform.

   e.g. for Linux

   asdf plugin add ruby https://github.com/asdf-vm/asdf-ruby.git
   
   # install version from .tool-versions file
   asdf install ruby
   
   asdf reshim ruby
   

   You will now be able to run the ./bin/dev command.

3. (optional) Install direnv and create an .envrc with

    #!/usr/bin/env bash
   
    PATH_add bin
   

   and then run direnv allow.

   You will now be able to do dev xxx instead ov ./bin/dev xxx.

Extras

If you want to take over a directory or file in Linux you can use dev ownit <path-to-directory-or-file>.

If you are on Windows or Mac, and you want that to work, you should implement it in the bin/dev file. You might never actually need to take ownership of anything, so this might not be relevant to you.
