Sherd

Crystal package manager, designed to be fast.

Experimental replacement to shards

The main purpose is to have faster dependencies resolution and download.

Features

• Fast, and light in memory, dependencies resolution
• Concurrent download of packages
• Compatible with shard.yml and shard.lock

Several features arestill lacking compared to shards.

Usage

Install locked dependencies:

sherd install

Build the first target:

sherd build

Configuration

The configuration file is sherd.ini and the lock file is sherd.lock, but shards.yml and shards.lock can still be used.

Dependencies

By default, dependencies will be cloned in Git/SSH, then HTTPS, if nothing is specified in the URI.

tag/ and heads/ match the syntax of git show. The only exception is commit:, which is the commit hash revision.

master will be taken if nothing is specified.

[dependencies]
first = github.com/user/first >=4.0.3 || <4.4.0
dep = github.com/user/dep1 tags/prerelease
somelib = https://gitlab.com/user/somelib heads/dev
otherlib = bitbucket.com/user/otherlib commit:1a400f9c6440fbrcb093066f54959eg9fbde5659

Scripts

Executes shell commands, or build a Crystal source file.

postinstall is a special key: the command will be executed at the end of the library installation.

The variable extra, like extra="--static", can be used to append extra instructions to the command.

Example:

[package]
name = sherd

[scripts]
postinstall = make
build = src/sherd.cr
build:test = src/other.cr

To run a script, use sherd exec [script name], or sherd e [script name]

If the string corresponds to a Crystal source file, it will be build with crystal build into bin/${package_name}.

Example: sherd e build extra="--static" will build statically a bin/sherd executable.

To change the binary name to build, add a name after a colon (like :test)

Example: sherd e build:test will build bin/test.

Multiple targets be run too:

Example: sherd e build run

Note: There is no targets nor executables sections compared to Shards.
