Julia Notes¶

Overview¶

I have created a seperate repository julia-notes where I will be documenting my exploration of the Julia language.

I will use this directory as a link and overview, with some special language features highlighted, and recipes included.

As always, this repository is a work in progress.

Working notes¶

Abstract typing in Julia is not a specification of data structure, and can indeed be field-less. Abstract types model behaviour for a set hierarchy.

Project Templating¶

For example, with PkgTemplate for creating the directory structure for a package:

using Pkg

Pkg.add("PkgTemplates")
using PkgTemplates

template = Template(; user="fjebaker")

And generate the project structure with

generate(template, "ProjectName")

Which will generate a new project in ~/.julia/dev/, but can be changed with the dir keyword in Template.

On `using` vs `import` vs `include`¶

In general, using when you are using the functionality, and import when you are intending to extend. include is different, in the sense of a C-like directive, which will “copy” the source code into the module, and becomes accessible as an extension; i.e.

module Something

using ModuleIwillUse

import ModuleIwillExtend

include("SubModuleIwantToExpose.jl")

end
