Interactive Redis: A Cli for Redis with AutoCompletion and Syntax Highlighting.

IRedis is a terminal client for redis with auto-completion and syntax highlighting. IRedis lets you type Redis commands smoothly, and displays results in a user-friendly format.

IRedis is an alternative for redis-cli. In most cases, IRedis behaves exactly the same as redis-cli. Besides, it is safer to use IRedis on production servers than redis-cli: IRedis will prevent accidentally running dangerous commands, like KEYS * (see Redis docs / Latency generated by slow commands).

Features

• Advanced code completion. If you run command KEYS then run DEL, IRedis will auto-complete your command based on KEYS result.
• Command validation. IRedis will validate command while you are typing, and highlight errors. E.g. try CLUSTER MEET IP PORT, IRedis will validate IP and PORT for you.
• Command highlighting, fully based on redis grammar. Any valid command in IRedis shell is a valid redis command.
• Human-friendly result display.
• pipeline feature, you can use your favorite shell tools to parse redis' response, like get json | jq ..
• Support pager for long output.
• Support connection via URL, iredis --url redis://example.com:6379/1.
• Support cluster, IRedis will auto reissue command for MOVED response in cluster mode.
• Store server configuration: iredis -d prod-redis (see dsn for more).
• peek command to check the key's type then automatically call get/lrange/sscan, etc, depending on types. You don't need to call the type command then type another command to get the value. peek will also display the key's length and memory usage.
• Ctrl + C to cancel the current typed command, this won't exit IRedis, exactly like bash behaviour. Use Ctrl + D to send a EOF to exit IRedis.
• Ctrl + R to open reverse-i-search to search through your command history.
• Auto suggestions. (Like fish shell.)
• Support --encode=utf-8, to decode Redis' bytes responses.
• Command hint on bottom, include command syntax, supported redis version, and time complexity.
• Official docs with built-in HELP command, try HELP SET!
• Written in pure Python, but IRedis was packaged into a single binary with PyOxidizer, you can use cURL to download and run, it just works, even you don't have a Python interpreter.
• You can change the cli prompt using --prompt option or set via ~/.iredisrc config file.
• Hide password for AUTH command.
• Says "Goodbye!" to you when you exit!

Install

Pip

Install via pip:

pip install iredis

pipx is recommended:

pipx install iredis

Brew

For Mac users, you can install iredis via brew 🍻

brew install iredis

Linux

You can also use your Linux package manager to install IRedis, like apt in Ubuntu (Only available on Ubuntu 21.04+).

apt install iredis

Download Binary

Or you can download the executable binary with cURL(or wget), untar, then run. It is especially useful when you don't have a python interpreter(E.g. the official Redis docker image which doesn't have Python installed.):

wget  https://github.com/laixintao/iredis/releases/latest/download/iredis.tar.gz \
 && tar -xzf iredis.tar.gz \
 && ./iredis

(Check the release page if you want to download an old version of IRedis.)

Usage

Once you install IRedis, you will know how to use it. Just remember, IRedis supports similar options like redis-cli, like -h for redis-server's host and -p for port.

$ iredis --help

Usage: iredis [OPTIONS] [CMD]...

  IRedis: Interactive Redis

  When no command is given, IRedis starts in interactive mode.

  Examples:
    - iredis
    - iredis -d dsn
    - iredis -h 127.0.0.1 -p 6379
    - iredis -h 127.0.0.1 -p 6379 -a <password>

  --client_name TEXT              Assign a name to the current connection.
  --raw / --no-raw                Use raw formatting for replies (default when
                                  STDOUT is not a tty). However, you can use
                                  --no-raw to force formatted output even when

  --help                          Show this message and exit.

Using DSN

IRedis support storing server configuration in config file. Here is a DSN config:

[alias_dsn]
dev=redis://localhost:6379/4
staging=redis://username:[e-mail]:6379/1

Put this in your iredisrc then connect via iredis -d staging or iredis -d dev.

Change The Default Prompt

You can change the prompt str, the default prompt is:

127.0.0.1:6379>

Which is rendered by {host}:{port}[{db}]> , you can change this via --prompt option or change iredisrc config file. The prompwt string uses python string format engine, supported interpolations:

• {client_name}
• {db}
• {host}
• {path}
• {port}
• {username}
• {client_addr}
• {client_id}

The --prompt utilize Python String format engine, so as long as it is a valid string formatter, it will work( anything that "<your prompt>".format(...) accepts). For example, you can limit your Redis server host name's length to 5 by setting --prompt to iredis --prompt '{host:.5s}'.

Configuration

IRedis supports config files. Command-line options will always take precedence over config. Configuration resolution from highest to lowest precedence is:

• Options from command line
• $PWD/.iredisrc
• ~/.iredisrc (this path can be changed with iredis --iredisrc $YOUR_PATH)
• /etc/iredisrc
• default config in IRedis package.

You can copy the self-explained default config here:

https://raw.githubusercontent.com/laixintao/iredis/master/iredis/data/iredisrc

And then make your own changes.

(If you are using an old versions of IRedis, please use the config file below, and change the version in URL):

https://raw.githubusercontent.com/laixintao/iredis/v1.0.4/iredis/data/iredisrc

Keys

IRedis support unix/readline-style REPL keyboard shortcuts, which means keys like Ctrl + F to forward work.

Also:

• Ctrl + D (i.e. EOF) to exit; you can also use the exit command.
• Ctrl + L to clear screen; you can also use the clear command.
• Ctrl + X Ctrl + E to open an editor to edit command, or V in vi-mode.

Development

Release Strategy

IRedis is built and released by GitHub Actions. Whenever a tag is pushed to the master branch, a new release is built and uploaded to pypi.org, it's very convenient.

Thus, we release as often as possible, so that users can always enjoy the new features and bugfixes quickly. Any bugfix or new feature will get at least a patch release, whereas big features will get a minor release.

Setup Environment

IRedis favors poetry as package management tool. To setup a develop environment on your computer:

First, install poetry (you can do it in a python's virtualenv):

pip install poetry

Then run (which is similar to pip install -e .):

poetry install

Be careful running testcases locally, it may flush you db!!!

Development Logs

This is a command-line tool, so we don't write logs to stdout.

You can tail -f ~/.iredis.log to see logs, the log is pretty clear, you can see what actually happens from log files.

Catch Up with Latest Redis-doc

IRedis use a git submodule to track current-up-to-date redis-doc version. To catch up with latest:

1. Git pull in redis-doc
2. Copy doc files to /data: cp -r redis-doc/commands* iredis/data
3. Prettier markdownprettier --prose-wrap always iredis/data/commands/*.md --write
4. Check the diff, update IRedis' code if needed.
