Julia Development Workflow

Set up a complete Julia development workflow with project activation, dependency installation, and Revise.jl hot-reloading.

Arguments

• path - Path to the project directory (default: current directory ".")

Instructions

Execute these steps in sequence:

1. Activate the project:

   activate(path="<path>")
   

2. Install dependencies:

   pkg(action="instantiate")
   

3. Load the package (if it's a Julia package with src/<PkgName>.jl):

   eval(code="using <PkgName>")
   

4. Verify Revise.jl is available:

   revise(action="status")
   

   If Revise is not available:

   pkg(action="add", packages="Revise")
   

   Then reset to reload (Revise auto-loads on startup).

5. Report the setup to the user:

   • Project path
   • Installed dependencies
   • Package loaded
   • Revise.jl status
   • Ready for iterative development

Development Cycle

Once set up, the iterative development cycle is:

1. Edit source files — Claude edits .jl files as needed
2. Hot-reload — revise(action="revise") picks up changes
3. Test — eval to run code, or pkg(action="test") for full test suite
4. Repeat — no session restart needed

For Package Development

When developing a local package alongside a project:

pkg(action="develop", packages="./path/to/MyPkg")

This puts the package in development mode. Combined with Revise, any edits to the package source are automatically picked up without restarting.

When done:

pkg(action="free", packages="MyPkg")
