Redis documentation

Clients

All clients are listed in the clients.json file. Each key in the JSON object represents a single client library. For example:

"Rediska": {

  # A programming language should be specified.
  "language": "PHP",

  # If the project has a website of its own, put it here.
  # Otherwise, lose the "url" key.
  "url": "http://rediska.geometria-lab.net",

  # A URL pointing to the repository where users can
  # find the code.
  "repository": "http://github.com/Shumkov/Rediska",

  # A short, free-text description of the client.
  # Should be objective. The goal is to help users
  # choose the correct client they need.
  "description": "A PHP client",

  # An array of Twitter usernames for the authors
  # and maintainers of the library.
  "authors": ["shumkov"]

}

Commands

Redis commands are described in the commands.json file.

For each command there's a Markdown file with a complete, human-readable description. We process this Markdown to provide a better experience, so some things to take into account:

• Inside text, all commands should be written in all caps, in between backticks. For example: INCR.

• You can use some magic keywords to name common elements in Redis. For example: @multi-bulk-reply. These keywords will get expanded and auto-linked to relevant parts of the documentation.

There should be at least two predefined sections: description and return value. The return value section is marked using the @return keyword:

Returns all keys matching the given pattern.

@return

@multi-bulk-reply: all the keys that matched the pattern.

Styling guidelines

Please use the following formatting rules:

• No need for manual lines wrapping at any specific length, doing so usually means that adding a word creates a cascade effect and changes other lines.
• Please avoid writing lines that are too long, this makes the diff harder to review when only one word is changed.
• Start every sentence on a new line.

Luckily, this repository comes with an automated Markdown formatter. To only reformat the files you have modified, first stage them using git add (this makes sure that your changes won't be lost in case of an error), then run the formatter:

$ rake format:cached

The formatter has the following dependencies:

• Redcarpet
• Nokogiri
• The par tool
• batch

Installation of the Ruby gems:

gem install redcarpet nokogiri batch

Installation of par (OSX):

brew install par

Installation of par (Ubuntu):

sudo apt-get install par

Checking your work

You should check your changes using Make:

$ make

This will make sure that JSON and Markdown files compile and that all text files have no typos.

You need to install a few Ruby gems and Aspell to run these checks. The gems are listed in the .gems file. Install them with the following command:

$ gem install $(sed -e 's/ -v /:/' .gems)

The spell checking exceptions should be added to ./wordlist.
