Dynamic folding and jumping to line IDs rely on unique IDs within the document
to work. If generated HTML is copied into a larger document, these IDs are no
longer guaranteed to be unique. Set g:html_id_expr to an expression Vim can
evaluate to get a unique string to append to each ID used in a given document,
so that the full IDs will be unique even when combined with other content in a
larger HTML document. Example, to append _ and the buffer number to each ID: >
:let g:html_id_expr = '"_".bufnr("%")'
<
To append a string "_mystring" to the end of each ID: >
:let g:html_id_expr = '"_mystring"'
<
Note, when converting a diff view to HTML, the expression will only be
evaluated for the first window in the diff, and the result used for all the
windows.
