The wrapper for jill.py and manage Julia environments with Python virtualenv
Project description
JILL Wrapper
JILL Wrapper (jillw
) is a lightweight and cross-platform Julia version manager. This work is based on johnnychen94/jill.py and Python venv.
jillw
targets several different use cases:
- cross-platform julia installation
- cross-platform julia version management (create, switch, remove, etc.)
- providing the "one Julia, one Python" installation
Installation
pip install -U jillw
Usage
Create environments
> jillw create --help
usage: create [-h] [--name NAME] [--upstream UPSTREAM] [--version VERSION] [--confirm] [--unstable] [name] [upstream] [version]
# create a new environment using Julia 1.8
> jillw create myenv --version 1.8
The explanations of the arguments except name
are referred to johnnychen94/jill.py.
Activate environments
> jillw switch <envname>
> jillw switch myenv
Start julia
under environments
> jillw switch myenv
> julia --compile=min --quiet
julia> Sys.which("julia")
"~/.jlenvs/myenv/julia/julia-1.8/bin/julia.exe"
List environments
> jillw list
myenv => ~/.jlenvs/myenv
latest => ~/.jlenvs/latest
Remove environments
> jillw remove latest
Environment latest removed.
Run commands under environments
> jillw switch myenv
> jillw run 'echo %VIRTUAL_ENV%'
~/.jlenvs/myenv
Configuring the julia
command (Experimental)
By creating a Development.toml
at a working directory, you can conveniently configure the julia
command to have the following features:
- reduce the startup time by using interpreted mode
- activate a project on startup
- preload some specified files on startup
- preload some modules on startup
Use jillw devhere
to create a template Development.toml
at the current working directory.
The following options can be modified to fit your needs:
-
min-latency
: a boolean that tells whether to use interpreted mode. This makes Julia code slow, but much faster at Julia startup and first-time module loading. -
no-startup-file
: a boolean that tells whether to load the~/.julia/config/startup.jl
file. -
project
: a string thats indicates the path to the project that is expected to be activated on startup. -
sysimage
: a string thats indicates the path to the sysimage that is expected to be used on startup. -
using
: a list of strings that indicates the modules that are expected to be preloaded on startup. -
files
: a list of strings that indicates the files that are expected to be preloaded on startup.
