expected an integer

Error message

expected an integer

What it means

Raised in parse_int while parsing snippet tabstop syntax when the parser expects digits (e.g. after `${` or `:` in a placeholder/choice) but the next characters are not an ASCII digit. The tabstop index is missing or malformed, so the snippet parse fails at that offset.

Solutions

1. Fix the snippet syntax: tabstops must be $0, $1, ${2:...} etc.
2. Remove stray $ or { characters
