618325 - Web Console use of tab for command line completion is inconsistent

Status: RESOLVED FIXED

(DevTools :: General, defect)

Description

[B.J. Herbison]

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.13) Gecko/20101206 Ubuntu/10.10 (maverick) Firefox/3.6.13 ( .NET CLR 3.5.30729; .NET4.0C)

Sometimes the Web Console completes a word with tab, and sometimes it goes to the next element.

For example, open the console with control-shift-K and type "cons" and "ole" will show up in gray and with "<tab>" and the word console will be completed.

Now type "." to the end of "console" and "classID" will show up in gray. Based on the previous behavior I expected <tab> to complete "classID", but instead "classID" was replaced with "error".

Reproducible: Always

I agree that this seems inconsistent. We'll have to think about alternatives (suggestions welcome)

It seems inconsistent until you understand what's happening. The tab key will iterate through the list of available properties if there is more than one. After completing "console" and entering a '.', you'll iterate through each of the properties. If you type a character, it will iterate through any remaining properties until you type another matching character, eventually with only one completion left, tab will finish the completion.

I think the best way to fix this would be to implement an actual popup showing the available completions in a list.

Requestion UI feedback for comments.
