Workaround low 'updatetime' intelligently
This should hopefully resolve the following issues and pull requests: #31, #33, #42. I tried several of their suggestions in Vim 7.2 & 7.3 but it didn't work as it should IMHO. All of the issues and pull requests seem to imply that CursorHold events fire continuously when you set a low enough updatetime, but in my testing on Vim 7.2 and 7.3 this is not true. The event fires once, then Vim waits for user input before any new events fire. I'm not sure exactly what user input is required; moving the text cursor is not always enough but mode switching is. So what happens (in my testing) with all of the proposed solutions is that you stop typing for 'updatetime' milliseconds, the event fires, the plug-in simply increments or decrements a counter and then Vim just sits there doing absolutely nothing expect blinking the cursor... What I'm now trying instead is to remember the last time the plug-in was executed (the result of localtime()) and not acting on the CursorHold event until the following condition holds true: localtime() > (last_automatic_run + (easytags_updatetime_min/1000)) I hope this provides a reliable solution. In any case it should be better than the previous annoying behavior :-)
