Aelve Guide

The beta version is running at guide.aelve.com. The most complete section yet is the one about lenses.

Installation instructions and the explanation of config variables (in config.json) are here: INSTALL.md. Don't be afraid to install it locally – it's very easy! You don't need to set up any databases or anything like that, and you can get a full copy of the data from the site by simply cloning it from Github.

Contributing

If you want to contribute but don't know where to start, grep the source for [very-easy] and [easy], or look at these issues:

• “your first pull request” – really easy things, with detailed “how to fix it” instructions
• “your second pull request” – less easy things, which assume that you already know where stuff happens in the code
• “not-fleshed-out idea” – discussion issues (“should we have users? what better ways are there to present pros and cons?”) which you can help with even if you don't know Haskell
• “design” – issues about design (which I'm not good at, and so help is wanted)

Testing

You need chromedriver and selenium-server-standalone installed (those are the package names on Arch Linux). Then you can do

$ java -jar /usr/share/selenium-server/selenium-server-standalone.jar

$ stack test

Overview of the code

Folder structure

• lib – actual code (as a library)
• src – just a dumb Main.hs file to compile an executable
• tests – tests
• static – icons, CSS, Markdown pages, HTML pages, and some JS libraries
• templates – HTML templates for pages and elements of pages
• scripts – some scripts used by automatic testing
• favicon – code used to generate a favicon
• guidejs – client side JavaScript
• front – the new frontend, written in Vue.js

Frontend

To lint Vue.js components, you need to do:

npm install --global eslint eslint-plugin-vue@next
cd static/components
eslint .

Maybe there's a better way than npm install --global, I don't know. I'm not a Node.js guy.

Notes

When you see something like

-- See Note [acid-state]

it means that there's an extensive comment somewhere else in the code, which you can find by grepping for Note [acid-state]. This convention was stolen from GHC. If you know some plugin for Emacs that would help with jumping to comments (even if those comments would have to be formatted differently), let me know.
