New Release - Firmware Version 1.02.06 for My Book World Edition I & II (1/4/2011)

Is rendered as:

The magic shanaigens should only happen if there is a space between it and other words… EG:

Sam and a 1/4 should get quarter magic
Sam was born 1/4/2001 should get no quarter magic.

I believe this is a default SmartyPants implementation, not our implementation. So the bug might be upstream for existing Ruby code…

The fix is clearly to convince the entire world to using proper (iso 8601) dates. Everything else is just stopgapping.

Yes, but I daresay there will be more topics about April 1st…

Raised:

the bug is here:

ext/redcarpet/html_smartypants.c

master


      
          	return 0;
          }
          
          // Converts 1/2, 1/4, 3/4
          static size_t
          smartypants_cb__number(struct buf *ob, struct smartypants_data *smrt, uint8_t previous_char, const uint8_t *text, size_t size)
          {
          	if (fraction_boundary(previous_char) && size >= 3) {
          		if (text[0] == '1' && text[1] == '/' && text[2] == '2') {
          			if (size == 3 || fraction_boundary(text[3])) {
          				BUFPUTSL(ob, "&frac12;");
          				return 2;
          			}
          		}
          
          		if (text[0] == '1' && text[1] == '/' && text[2] == '4') {
          			if (size == 3 || fraction_boundary(text[3]) ||
          				(size >= 5 && tolower(text[3]) == 't' && tolower(text[4]) == 'h')) {
          				BUFPUTSL(ob, "&frac14;");
          				return 2;
          			}

In particular word boundary is defined as: isspace(c) || ispunct(c); , ispunct includes /

Yeah, because David/Gene/Edward does seem like a word break to me. You could specialize it to numbers and say a slash between numbers is not a word break.

waiting for it to be accepted

we are carrying a lot of GEM around for this 1 c file out of the 20 it ships

Change is accepted, waiting on a stable release

sam · 9월 24, 2015, 3:39오전

This is now fixed per:

https://github.com/discourse/discourse/commit/ffb8cb8caca2f0b73c480b96a2b753ef5866a91e

We no longer ship the Redcarpet gem, we have a pure Ruby implementation of title prettify that is included in our code base.

Before:

After:

We no longer have to wait months for title prettify fixes.
