In-app editor

Editing a file without changing window

Everything slope hot-reloads is a text file, and E opens an editor on those files inside the running presentation. You can correct a shader, retype a line of pseudocode or add a slide to the deck, wtithout a text-editor.

The list on the left is every watched file: the deck, the latex definitions and preamble, Lua snippets, shader sources and their includes, and the files shown as code or pseudocode.

The editor only writes to disk. The same file watch used for an external editor reads the change on the next frame, so saving is what reloads.

Keys

Key	Action
E	open and close the editor
Ctrl + S	save the open file, which reloads it
Ctrl + /	comment or uncomment the selected lines, in the language of the file
Tab	indent, two spaces in a yaml file
Enter	a new line, indented like the one it ends
Ctrl + C / X / V	copy, cut, paste
Escape	leave the text field, then close the window

The size slider scales the editor font. Syntax highlighting is the one a code primitive uses, and covers the same languages.

Files that do not exist yet

A file a deck names but that does not exist is shown greyed out in the list, with a Create file button. Write shader: new.glsl in the deck, then create the file from the list.
