Limitations of custom delimiters

[rauschma]

Status quo

These are some of the current tokens:

• <%
• <%=
• <%-
• <%%
• %>
• -%>

We can specify:

• delimiter
• openDelimiter
• closeDelimiter

Then % in the tokens is replaced with delimiter, < with openDelimiter and > with closeDelimiter.

I see two issues with that approach:

• If delimiter is (e.g.) = or - then escaping doesn’t work. It also looks odd if delimiter is more than one character.
• It limits the open and close delimiters we can specify. Recent use case I had:
  • Open with '/* ' (space after *)
  • Close with '*/' (no space)

Suggestion

Let us specify:

• openDelimiter: the whole open delimiter
• closeDelimiter: the whole close delimiter
• escapedOpenDelimiter. Default: openDelimiter + '%'
