In Atom-Nuclide for simple errors (indentation, semicolons, const etc) it appears a tooltip with a button to fix it automatically.
This is very useful but still a bit time consuming.
Is there a way to automate it with a command or a macro that simulates clicking on all the fix buttons?
Alt+Shift+A
does what you want (default on Linux).
The command is called "Nuclide Diagnostics: Fix all errors in current file", I found it using the command-palette.
