Elm Format

In an effort to standardize how Elm code should be formatted, elm-format was created. It is still in alpha, but I figured you might just as well start playing with it.

Precondition

You will need to install elm-format and make sure the executable is available in your path for it to work from the plugin.

Format editor contents

• With an elm file open, select the command Elm: Format editor contents

• If no errors the whole editor is formatted (but any format changes aren't saved)

• If there are any errors (typically syntax errors), a message is shown in the Statusbar and details can be found in the console

Format top level expression

If for some reason you find yourself wanting to just format a top level expression, this is the command for you.

• Place the cursor somewhere within the top level expression you wish to format

• Select the command Elm: Format top level expression at point

Format a file

With an elm file open, select the command Elm: Format file

WARNING: Any unsaved changes will be lost when running this command. This command updates the file backing the editor in question.

Adding keyboard shortcuts

[:editor.elm.common "cmd-shift-l" :elm-format-expression]````[:editor.elm.common "cmd-ctrl-l" :elm-format-buffer]

Configuring indent in Light Table

[:editor.elm.common :lt.objs.editor/tab-settings false 4 4] ;; or 2 2 if the war continues and things change back
