screencast

changes

This new version is going to be more portable and the web interface will be detatchable.

Command line apps can be automated, typically using a docer image and a shell script

app do this
app do that --parameter=12345
etc.
Automating a web interface is not practical.

This app reminds me of jupyter which runs code in a browser

the first version

First one was built for windoows platform and got too bloated, this one will be primarily for linux, but I might add .net core if I run into a demand for it.

The original also used celery distributed job scheduler and another standalone python scheduler, have to find the link for that one...

It also had scaffolding & deployment tools, and monitoring built in.

I doubt I'll migrate those features over, it's overkill for anything I am working at the moment and I'm having more fun working on micro projects rather than big monoliths which generall become clunky slow and not fun.

snippets

this is the messy django view, it does 3 things right now

  • list the folders
  • lists the files
  • lists the contents of the file

later it will

  • detect the language using the file extension
  • have a db model so you can select a server to run the code against
  • the run button will work which will execute the code from a command line
  • a copy to clipboard button on all snippets
  • have a rules model where you can stack them up in sequence (many to many)
