My workflow (REPL-based, Juno in particular is probably different):
- Open a file ("MyModule.jl") that will consist of a single module, and
contains types & code
- Open a 2nd file ("mymodule_tests.jl") that will be the tests file for the
module. Inside of this file, say `import MyModule` rather than `using
MyModule`; you'll have to scope all calls, but that's a small price to pay for
the ability to `reload("MyModule")` and re-run your tests.
- Open a julia REPL
- Start playing with ideas/code in the REPL. Paste the good ones into the
files. And sometimes vice-versa, when it's easier to type straight into the
files.
- When enough code is in place, restart the repl. Cycle through
reload("MyModule")
include("mymodule_tests.jl")
<edit these two files>
until things actually work.
