Vim syntax looks like BRE (*not* ERE) on steroids unless you use very magic modifier at the start of regex. It looks like nothing else if you do. It is vim who has unique syntax. PCRE has a bunch of similarities with ERE (nearly any ERE regex can be used without modifications with PCRE) and is pretty common: Perl 5, Python, Ruby, go, PHP, grep (if build with PCRE support and provided -P switch), zsh (if build with PCRE support and some options enabled or specific comparison switch is used). Note that neither Python nor Perl are actually using PCRE: Python just borrowed the syntax and Perl is where PCRE borrowed syntax from. Do not know which of the other languages I mentioned with PCRE-like regex syntax are actually using PCRE. Thus by bringing this argument you contradict yourself: if you want to leverage learning across utilities you must use PCRE. > Erik > > -- > The Kyoto Protocol, drafted in 1997, aimed to reduce the world's greenhouse gas > emissions by around five per cent from 1990 levels by the end of 2012. > Instead, global greenhouse gases have risen around 58 per cent in that time. > - http://www.abc.net.au/news/2012-12-08/troubled-un-climate-talks-spill-over/4416696 > > -- > -- > You received this message from the "vim_use" maillist. > Do not top-post!
