Mundler

A simple tool help download and compile mruby when gems in your project change, automatically keeping track on whether a recompile is necessary or not.

Inspired by the ease-of-use of bundler, but certainly not the equivalent. This gem itself doesn't deal with dependency management or downloading the gems itself as mruby itself handles that all perfectly well.

Run:

$ gem install mundler

Put a Mundlefile at the root of your project and run mundle install (or just mundle). A Mundlefile.lock will be generated with the format of mruby's build_config.rb. The install will use this config to configure the compilation of mruby.

A Mundlefile declares desired gems. For example:

mruby tag: "3.0.0"

platform "ios", archs: [:armv7, :arm64]
platform "ios_simulator", archs: [:i386, :x86_64]

gembox "default"
gem "mruby-regexp-pcre"
gem "mruby-iijson"
gem "mruby-secure-random"
gem "mruby-eval", core: "mruby-eval"

Cached (source and compiled) versions of mruby will sit under ~/.mundler.

mundle clean will clean the mruby cache (of the mruby version applicable to the Mundlefile).

mundle update is the same as mundle clean and mundle install.

mundle exec execute a commands with mruby's bin prepended to $PATH (of the mruby version applicable to the Mundlefile)

mundle path prints out the path relevant to the compiled version of mruby relevant to the Mundlefile. This can be useful for using in compiler flags.

mundle summary will print a summary of the compiled binaries and libraries.
