From 35583c3dec4e060c4845ba7b8fb25af6176bef60 Mon Sep 17 00:00:00 2001 From: Trevor Buckner Date: Thu, 7 Apr 2022 21:52:55 -0400 Subject: [PATCH] fix: allow emStrong regex to consume more characters at once (#2433) Just a small tweak so `emStrong` regex doesn't have to check character-by-character. Try to consume everything up to the delimiter we are checking for. --- src/rules.js | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/src/rules.js b/src/rules.js index bb8b384884..58b917d2b2 100644 --- a/src/rules.js +++ b/src/rules.js @@ -168,9 +168,9 @@ export const inline = { emStrong: { lDelim: /^(?:\*+(?:([punct_])|[^\s*]))|^_+(?:([punct*])|([^\s_]))/, // (1) and (2) can only be a Right Delimiter.
