Atom

A text editor I seemed to be using


Atom -- a code editor made by Github, easily extensible because much like emacs, it’s mostly written in a dynamic language (javascript) and is open source. Unlike emacs, it’s not currently in an apparent evolutionary cul-de-sac. Powerful. Slow and RAM-hungry. I have given it up for VS Code.

Misc tips

What scope is my current document?

I don’t know. Run Editor: Log Cursor Scope.

Notable extensions

  • symbol-tree-view for bearable navigation between definitions.
  • remote-atom allows you to edit files on remote servers that you don’t want to use vim on.
  • teletype enables generic live collaborative document editing

Panes

tl;dr if a pane has an italic header, double click on it to keep it. Be aware the pending pane feature is handy but will confuse the crap out of you if you expect Atom not to try to guess whether you want to look at a file temporarily or permanently.

Atom as a platform

People can and do build whole IDEs in atom.

jupyter

hydrogen turns atom into an interface to jupyter kernels, for live code inspection and execution.

julia

Juno is an IDE for julia which I personally don’t particularly like because a single-window IDE is claustrophobic.

other

Nuclide is Facebook’s extensions to atom for web-centric development. I don’t use it because I’ve served my webdev time, but web people might care about it.
