JVM: The Julia Version Manager

A ridiculously simple dependency manager for Julia packages.

Installation

Pkg.clone("[email protected]:tmlbl/JVM.jl.git")
Pkg.build("JVM")

JVM is a command-line utility that uses Base.Pkg to create and manage a localized package directory for managing explicit dependencies per-project.

Run jvm init in your project directory to create a .jdeps directory and a JDEPS file. You can then add dependencies using jvm add [pkg] [version].

~$ jvm add AppConf 0.0.3 # Add v0.0.3 of the AppConf package
~$ jvm add HttpCommon # Leave the version out to install the current version
# You can add unregistered packages as well
~$ jvm add [email protected]:tmlbl/Oanda.jl.git

Registered packages will be tracked by their version numbers. Unregistered packages will be tracked by SHA. Unlike REQUIRE, all dependencies will also be recorded at their explicit versions in JDEPS. If are running a project that includes a JDEPS file, you can fetch those dependencies by running jvm install. Then, run the project by setting JULIA_PKGDIR to the created .jdeps directory. Or, you can use the built-in shortcut to temporarily reassign JULIA_PKGDIR:

~$ jvm run app.jl

Running jvm package will create a julia_pkgs.tar.gz of unbuilt packages that can then be copied to and built on a target machine, or built inside a Docker container to create a Julia Virtual Machine.

~$ jvm init
~$ jvm add LevelDB
~$ jvm package

Dockerfile:

FROM julia:0.4.0

RUN apt-get update
RUN apt-get install -y wget build-essential libsnappy-dev

ADD . /opt/src
WORKDIR /opt/src
RUN tar xvf julia_pkgs.tar.gz
ENV JULIA_PKGDIR /opt/src/.jdeps.pkg
RUN julia -e "Pkg.build()"
ENTRYPOINT julia /opt/src/script.jl

Run jvm with no arguments to see help information.
