Insert next level header

Use case or problem

When I’m writing my notes I tend to user a variety of different header levels (i.e. #, ##, ###, etc) and I often want to add a new header within the current section and within the Live Preview Editor it’s difficult for me to know the next level down (i.e. if the current section has a ## heading then I want to insert ###).

Proposed solution

So my proposal is to add a command with a name similar to Insert next level header that will look for the nearest header above the cursor and then insert a new line with the correct heading level.

Current workaround (optional)

Either:

  • Move my cursor up to the nearest header to check what level heading it is then move the cursor back to where I was to insert the next level heading manually
    • I don’t like this because it takes time and interrupts my flow
  • Run Toggle Live Preview/Source Mode
    • This often doesn’t work well because if there’s lots of rich text/links/images on the page the heading will jump around significantly.

If they’re going to add “Insert child heading”, they should also add “Insert sibling heading”

If they’re going to add “Insert child heading” and “Insert sibling heading”, they should also add “Insert parent heading”. :wink:

@axelson here’s a quick and easy Templater script to do exactly this:

<%*
// Get the document content up until the current cursor position
const lines = app.workspace.activeLeaf.view.editor.getCursor().line
const content = tp.file.content.split('\n').slice(0, lines).join('\n')

// Get an array of headings from the previous document content
const headings = content.match(/^#+ \S/mg)

// Get an integer representing the previous header level
const prevHeaderLevel = headings.pop().match(/^(#+)/)[1].length

// Output a child header
tR += '#'.repeat(prevHeaderLevel + 1) + ' '
%>

@obsequious @CawlinTeffid For sibling or parent header it would be this:

// Output a sibling header
tR += '#'.repeat(prevHeaderLevel) + ' '

// Output a parent header
tR += '#'.repeat(Math.max(1, prevHeaderLevel - 1)) + ' '

Assign the Templater script to a hotkey, and you can insert a child/sibling/parent header anywhere you wish.

@AlanG Awesome, thanks!

Is there a way to not insert a newline after the hash signs? Maybe triggering a backspace?

It doesn’t insert a newline for me. It does insert a space though, if that’s what you meant?

Just remove the + ' ' from the last line of the script.

<%*
// Get the document content up until the current cursor position
const lines = app.workspace.activeLeaf.view.editor.getCursor().line
const content = tp.file.content.split('\n').slice(0, lines).join('\n')

// Get an array of headings from the previous document content
const headings = content.match(/^#+ \S/mg)

// Get an integer representing the previous header level
const prevHeaderLevel = headings.pop().match(/^(#+)/)[1].length

// Output a child header
tR += '#'.repeat(prevHeaderLevel + 1)
%>

Most likely you have a newline at the end of your template file. The template will insert exactly what’s in the file, so if you add blank lines, it will insert blank lines:
