the RegExp is not correrct, it can not match url start with 'http'

[shuidian]

the RegExp(\\[${config.tag}\\]\\((http|https://.+)\\)) can not match url that start with http.such as: 'https://raw.githubusercontent.com/docsifyjs/docsify/develop/README.md' the correct RegExp may be like this :RegExp(\\[${config.tag}\\]\\((http://.+|https://.+)\\))

[AlexYegupov]

...or mayve even RegExp(\[${config.tag}\]\((.+)\));

to support local markdowns like './mylocalfile.md'
