Id used twice

A heading is given an id in braces, ## Title {#id}, that something earlier on the page already has: another heading given the same id, or a footnote. Statac writes footnotes’ ids itself: note-1, note-2 and so on for the notes, and back-1 and the like for the markers pointing at them. The message points at the second, and shows the first heading where there is one.

What you’ll see

warning  Id used twice: a heading above has the id `rust`
  Give this heading an id of its own.

In the terminal the message also names the file and line where there is one, and marks the exact text.

Why Statac warns

An id names one place on a page. A link to it lands on the first thing that has it, so the second heading can’t be linked to. Statac keeps the id as you wrote it, since it is yours, and tells you. An id Statac makes from a heading’s words never takes one you wrote: it gets a number instead.

How to fix it

Give the heading an id of its own, or leave the braces off and let Statac make one from its words. Ids starting note- or back- belong to the footnotes.

Example

In content/post-1.md:

## Getting there {#route}

## Coming back {#route}

Give the second heading its own id:

## Getting there {#route}

## Coming back {#return}

Its name

Name	id-used-twice
In the terminal	statac explain id-used-twice
To stop showing it	quiet: [id-used-twice] in statac.yaml, once you have understood it. Statac still counts it.
