Hi Pavilioners, I thought I’d write some aide-memoire notes for myself about things I sometimes forget about Discourse development, but also thought while I was doing so I’d describe my setup in a bit more detail, in case this helps any members or the wider community - also because I might get helpful tips and feedback myself!
I’m using my general purpose laptop which I use for everything else - a Dell XPS15 9560 laptop with 4K/QHD screen, 32Gb RAM and a 1Tb NVMe SSD.
I run Linux Mint (currently on 19.3 which is latest, and is built on Ubuntu 18.04 LTS
General development setup
I use Atom for most development (Nano if I’m editing a file on a server over SSH). I don’t have extensive editor customisations, it’s basically stock. I add a few custom keyboard shortcuts.
- a community-driven suite of customisations, themes and tools for ZSH, including a lot of very useful Git aliases and helpers. The Git branch prompt and ruby version prompt is very useful.
I generally use Firefox now, unless I’m testing something across different browsers, or need a Chromium-based browser because some Google thing refuses to work, in which case I use Brave.
Firefox has the ability to
Ctrl-Tab between tabs in Most Recently Used order, which I find super valuable for switching tabs quickly without mousing.
- I use the CopyQ cross-platform open source clipboard manager, which I use to allow me to keep the last 1000 clips in a palette of clipboard, which is really useful and time saving.
You can drag any particularly useful snippets across into a ‘persistent’ tab.
copyq: copy(mimeText, 'firstname.lastname@example.org', mimeHtml, '<a href="mailto:email@example.com">firstname.lastname@example.org</a>') paste()
- a script which slugifies any clipped text for me: (I use this for filenames and Git feature branch names taken from a relevant Issue that it’s supposed to fix, for projects that work like that)
copyq: // lowercase, replace non-word with hyphens, trim multiple hyphens, trim leading and trailing hyphens text=str(clipboard()).toLowerCase().replace(/\W/g, "-").replace(/-+/g, '-').replace(/^-|-$/g, '') tab(selectedtab()) write(0, 'text/plain', text) copy('text/plain', text) paste()
wd - ‘warp directory’
- neat little utility which is a plugin for
oh-my-zshthat lets you jump to a directory quickly with less typing. ohmyzsh/plugins/wd at master · ohmyzsh/ohmyzsh · GitHub
- yes, I guess you could define aliases to do the same, but you’d need to keep
echoing the aliases into a
.*rcfile to make them persistent.
Discourse development setup & workflow
I develop using Discourse Docker - the documentation on Meta was recently refreshed it seems, and it much clearer than it was.
Performance is acceptable, no worse than it was in a VM, probably better.
Useful commands to develop with Discourse Docker
|Run bundler to install/update gems||
|Migrate and seed the database||
|Clear cache and start server||
|Run a Rails command||
|Run a Discourse CLI command||
Quick way to install latest Docker:
curl -fsSL https://get.docker.com/ | sh
sudo groupadd docker
sudo usermod -aG docker $USER
sudo systemctl restart docker
(also need to log out and in again to pick up the addition of user to
- try to keep things clean by moving the plugin symlinks in and out of the
pluginsdirectory. Plugins not currently being worked on are moved to a
plugins-availablefolder, a bit like how sites are managed in NGINX/Apache.
Gotchas (mainly for me when I forget)
Symlinking plugins into the
- symlinks MUST contain an absolute path not a relative path, or the
d/boot_dev --initcommand will fail silently, and your
discourse_devDocker container will not exist.
