* bug#24709: 26.0.50; Support for Markdown in electric-quote-mode @ 2016-10-16 17:19 Philipp Stephani 2016-10-19 11:10 ` Alan Third ` (2 more replies) 0 siblings, 3 replies; 7+ messages in thread From: Philipp Stephani @ 2016-10-16 17:19 UTC (permalink / raw To: 24709 When editing a Markdown document with electric-quote-mode enabled, the experience is not optimal because ` (backtick) in Markdown is a syntax element (for introducing code spans and blocks), but is converted by electric-quote-mode. Also ` and ' inside code spans and blocks continue to insert curly quotes where they shouldn't. I propose the following: - Provide an alternative behavior of electric-quote-mode where ` doesn't trigger replacement and ' can insert left or right curly quotes, depending on whether it follows a space or similar (newline, beginning of buffer, opening parenthesis). - Provide a way to disable electric-quote-mode for certain regions, effectively the inverse of the existing electric-quote-string etc. This could be in the form of syntactic elements or text properties.
