RiKi, I have been through this (curly removal) before.
While Perl can remove braces easily and quick and dirty as in s/\{//g; s/\}//g; this will remove ANY and ALL curlies. If the LyX document contains other curlies they will also go. So you might need to copy the formula from the LyX file into a buffer, remove the curies and then paste again. Writing a Regular Expression to do this intelligently (ie working from the outside braces to the inside) is extremely difficult. Never mind how the LyX code actually looks like. (I.e. who are the curlies represented there) Zhao, can you post a minimal working example LyX file here? A line of text or two and one single imported math formula. greetings, el On 01/03/2020 02:11, Richard Kimberly Heck wrote: > On 2/28/20 10:52 AM, zhao_yuns...@cnu.edu.cn wrote: >> Hello there >> I have a lyx file converted from a LaTeX file. >> But in the formula of the lyx file, there are a lot of paired braces, >> as is shown blow.
