Merchant: A package manager for the Mercury logic programming language.

Merchant is a command line tool that downloads your Mercury project's library dependencies and compiles your project.

Installing Merchant

$ git clone https://github.com/stewy33/merchant
$ sh merchant/install.sh

Test that Merchant is installed by running:

$ merchant version

Create a default config:

$ merchant configure --reset-config

This creates a platform-specific global configuration file at ~/.merchant/config.json, like the one below:

{
    // default config file for OSX
    "build_profiles" : {
        // arguments before "--" are passed to "merchant build", everything after is passed to the mmc compiler
        "default" : "-- --grade none.gc.decldebug.stseg",
        "dev" : "-- --grade none.gc.decldebug.stseg --opt-level 0"
    },
    
    "install_profiles" : {
        "default" : "-- --no-libgrade --libgrade none.gc.decldebug.stseg",
        "dev" : "-- --no-libgrade --libgrade none.gc.decldebug.stseg --opt-level     0"
    }
}

The config file is editable, and sets default installation and build profiles. If you create a new build profile, called production for example, you could build your project with it by running:

$ merchant build --profile production

You can use the config file to set install and build options per system.

Using Merchant

Basic Usage

1. Inside project folder, generate manifest file with merchant init.
2. Edit manifest.json with project name, author, dependencies.
3. After each update to manifest.json, run merchant install, and merchant build to compile the project.

Example Manifest file

{
    "name": "test", // should match name of main module
    "author": "Stewy Slocum",

    "dependencies": {
        "mercury_json": "https://github.com/stewy33/mercury-json"
    }
}

NOTE: This project has only been tested on Mac and Linux, though it will probably work on Windows with Cygwin or Ubuntu shell.
