apmtool in the CLI:
apm install linter-julia
You may need to tell linter-julia where to find the Julia executable
C:\Julia-1.5.3\bin\julia.exe). The default assumes 'julia' just works.
Julia must have the General registry added.
The code generates its private shared environment at the Julia depot in 'environments/linter-julia'. It also places a logfile there.
Guessing the environment works by walking upwards in the path and looking for Project.toml. If nothing found, the default environment is assumed. The project's root file is then looked for at the canonical X/src/X.jl etc. locations.
I know nothing of Atom development or js, so the changes are likely messy there, please revise. Atom seems to be unable to shut down the server process, so the server exits by polling Atom's PID right now.
Good catch. Let us know what about this package looks wrong to you, and we'll investigate right away.
