Iris - A GUI library to visualize function call paths of your codebase

rahultumpala

Hello Elixir community,

I work primarily on Java and other object oriented programming languages and often found it difficult to read an elixir codebase, to recollect what I have written when re-visiting my code after a break.

To help with this, I built the iris library.

Iris generates a webpage from your codebase and lists all your applications, modules and methods. Method call paths are also generated and visualized. You can use this to teach explain product managers about your codebase!

I am unable to add a screenshot here as I’m a new user. Please click on the link to see the screenshot in my github repo.

I would love to hear your feedback on the library. Please try it out !

Thanks!

Installation

def deps do
  [
    {:iris, "~> 0.1.0"}
  ]
end

Usage

$ mix iris

Hello Elixir Community,

Please find the interactive demo for this project generated by iris and hosted on HexDocs in the IrisUI section of the docs located at iris v0.2.3 — Documentation

Alternatively IrisUI can be directly found at https://hexdocs.pm/iris/irisui,html

Again, your feedback is much appreciated.

Thank you!

Very cool, however quite heretical to refer to functions as “methods”

Hazards of writing java a lot – everything starts looking like a method.

Hi, I wanted to try iris, but it broke with a dependency conflict. Would it be a good idea to make it installable as escript like: mix escript.install hex iris?

@rahultumpala it would make sense to restrict ex_doc to only: :dev here: iris/mix.exs at main · rahultumpala/iris · GitHub like

- {:ex_doc, "~> 0.38.4"}
+ {:ex_doc, ">= 0.38.4", only: :dev}

Indeed, this fixes the issue. Thanks @mudasobwa .

@ouven please retry with v0.1.3.

I am not entirely clear about the usage of escript.install mix task. Let me check on this.

Thank you! Works great.

Do you plan to also support umbrella apps?

Yes, its in my queue. Hopefully I can publish it by end of this month.

I played around with your example and it’s surely an interesting library. Well done!

A couple of things that I noticed:

you are not using tags in your github repo and therefore your documentation doesn’t go to the correct code
it would be nice if you could move from the iris documentation to the hexdoc documentation (and/or to the actual code). I have seen the “Documentation” icon which pops up the ExDoc documentation for the @moduledoc, but then you can’t get any further
Also the “Documentation” for function @doc doesn’t open when you select it, you need to click on the icon in the graph once more.
