I disagree with that. The existing JDT content assist is expected to return results fast. Slow completion processors are flagged and disabled. So, there won't be more delay than when you currently type '.' or invoke Ctrl+Space. Did you try it before commenting here?

The issue is not whether to use a workaround or not - it's quite easy to add a preference that auto-invokes completion with any keypress.

The foremost issue is what Mickael Istria mentioned: the completion API needs to be adapted to work in asynchronous mode, instead of in the UI thread. Otherwise, enabling auto-invocation of completion is almost certain to be a grief to the user.

There's no need for a regex or adding more complexity. Entering the characters is just a current hack/workaround. What we would have to add is support to support auto-completion at any position after the specified delay.

Good point....would an exclusion string or RegExp work ?
 
Perhaps it's irrelevant; the concept of content assist 'trigger' sounds like it's language specific (in more ways than one...;-). Is there an LSP concept for this ? To get the best experience we need to have as much context as possible to filter / rank the results (things like whether the editor is expecting a field, methods with different args...).
 
Just for my interest do you know how close preference change approach comes to mimicking IJ ?

What if I’m using Unicode characters in my identifiers, do I have to enter all 32000? Sorry, that workaround is a bit silly. And it sounds like there are a lot of issues to solve before we even get there anyway.

Re: [ide-dev] Auto content assist

 
For at least some editors (java) this can be controlled through preferences...Preferences->Java->Editor->content assist has a value called 'Auto-activation triggers for java'. it's defaults to '.' but if you change it to 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ.' then it'll always invoke content assist (much closer to the IJ feel).
 
Onwards,
Eric

Then I switched back to Eclipse to do some CDT work and typed the beginning of an identifier and expected content assist to just pop up. I forgot that I had to ask the editor to pop it up for me. Auto content assist is one of those features that once you start using it just becomes natural.
It's also a reason why some people do prefer IJ for Java development. Auto content-assist is a must-have nowadays.
