Package Development in Julia

Start out by developing as a simple set of files to be included, say “/home/henry/devel/MyCode.jl”
- use by calling: julia> include(“/home/henry/devel/MyCode.jl”)
When ready to make it a real package
- Create a git repo with the name of the package, e.g. “MyPkg”, in ‘~/.julia/dev’:
  - cd /home/henry/.julia/dev
  - julia> generate MyPkg
  - cd MyPkg
  - git init
  - git add -A
  - git commit -m’init’
- Add it to the repo management
  - julia> ] develop /home/henry/.julia/dev/MyPkg
- Add the files to that freshly made package
  - echo “module MyPkg” > /home/henry/.julia/dev/MyPkg/src/MyPkg.jl
  - cat /henry/devel/MyCode.jl >> /home/henry/.julia/dev/MyPkg/src/MyPkg.jl
  - echo “end” > /home/henry/.julia/dev/MyPkg/src/MyPkg.jl
- Add dependencies
  - ] activate .
  - add LinearAlgebra
  - add …
  - …
  - restart julia
  - ] resolve
Now the package is available as
- using MyPkg
When you are ready for sharing it with friends
- create a (private) repo on github: MyPkg
- git push –set-upstream git@github.com:vonDonnerstein/MyPkg.git master
other people can start using it
- by clone-ing the repo to their ~/.julia/dev and
- ] develop ~/.julia/dev/MyPkg
