Crul

Crul is a curl replacement, that is, it's a command line HTTP client. It has less features and options, but it aims to be more user friendly. It's heavily inspired by httpie.

It's written in the Crystal language. It's in an early stage but it allows already basic usage.

Features

• Fast
• No dependencies, easy to install
• Basic HTTP features (method, request body, headers)
• Syntax highlighting of the output (JSON and XML)
• Basic authentication

Planned features

• User friendly headers and request body generation (similar to httpie's)
• Digest authentication
• More fancy stuff

Installation

Mac

brew tap porras/crul
brew install crul

Or, if you prefer, download the latest release and unzip it somewhere in your $PATH.

Linux

The latest release includes a Linux 64 bits binary that reportedly works on:

• Ubuntu 12.04 LTS
• Ubuntu 14.04
• Debian testing

If you're a user of those distros (or a different one and want to help trying), download it and unzip it somewhere in your $PATH.

If you use a different distro, you'll have to build it from the source code, see Development.

Development

After checking out the repo (or decompressing the tarball with the source code), run make to run the tests and compile the source. Optionally, you can run make install to install it (as a default, in /usr/local/bin, override it running PREFIX=/opt/whatever make install).
