Hi all, Forgot to add, you can invoke it on a page with ":esource". If there was a demand for it, this could probably be updated to actually copy the full page source instead of relying on the jsapi_eval call to pull the innerHTML (outerHTML is closer but still excludes the doctype) and resave without the jsapi as well. -Matt On Fri, May 02, 2014 at 02:27:29PM -0400, Matthew Carter wrote: > Hi all, > > Attached is a patch to do what Marcos described, it also lets you edit > the source and upon saving and quitting your editor, it updates the > page's source code to match what you changed. > > Uses the same logic and URI handler as the special textarea editor > handling. > > It does not include the surrounding <html> tags or the doctype as that > makes it difficult to refresh the browser with what was edited (so > essentially you're getting a view of the > document.documentElement.innerHTML, which you can then change/look > through in your editor of choice). > > Thanks, > -Matt > > On Sun, Apr 20, 2014 at 03:35:10PM +0200, Marcos Cruz wrote: > > Hi all, > > > > Sometimes, when I need to examinate the source of a page, I prefer to do > > it with all the power of Vim instead of the internal viewer.
