Can't select anything on the first line of XML file using the mouse #3009

I can't reproduce your issue. Am I doing it right? Tested on:
|
|
I'm on Win8, atom v116, and it's working for me too, no problem here. |
|
Possibly fixed in 0.116 then, maybe also only on Windows? I will try again on Monday when I'm back at my desk. @lee-dohm Steps look correct to me. I will see if it's specific to the XML passed in by trying with some more variations. |
|
Are you using the react editor? |
|
I was using the React editor, yes. So that is definitely something to try. |
|
Ok, I've done some more testing. It turns out I just wasn't being patient enough - I can select text, it's just incredibly laggy (2-3 seconds on a quad core desktop). The first line of the document I was using is over 4000 characters long. Enabling soft wrap makes it much quicker to select characters on the top line. Sample file pasted below: |
|
I tried your file as well, also on Win8, quad-core, and couldn't find any noticeable lag: Even selecting it all with Do you use packages that may interfere with selection? Edit: You said it was all on one line, so I removed \n and \r before this test. |
|
@batjko Disable wrapping. What are you using for those screen grabs by the way? I've not got any packages installed, I just did a standard "choco install Atom" install. |
I didn't say it was all on one line, just that the first line was very long. |
|
@tjrobinson Disabled wrapping and still no issues here: I'm using LiceCap. It's old and ugly, but simple and works just fine. Sorry I can't replicate what you're experiencing. The only difference is that I didn't use chocolatey. |

Hopefully this will make the behaviour clearer. I create a new document, paste my XML (straight from this issue report), press HOME, try to select some text on the top line (note the delay after I swipe). I then try selecting it a few different ways. As I said before, it does work, just very slowly sometimes. It seems to improve the longer Atom has been running. Note that when I select text on lines 2,3 and 4 it's very quick. |
|
Yes that's what I understood. I just tried to increase the effect by putting it all on one buffer line, but I tried various formats of the text, various ways of selecting etc. Never fails me. I'm not sure how to debug this, other than to run Also possible is a memory issue, I suppose? |
|
Safe mode doesn't make any difference, Windows reports 7GB of RAM free. Atom is using 21MB. |
|
@tjrobinson Does this issue cover the performance problems you described here? If not, could you add a comment to that issue; seems like this is related to long lines, not XML or the first line? Also, does turning on react editor mode in Atom > Preferences > Settings help? It should help -- I can reproduce the slow selection behavior when react is turned off, and can't if it's turned on. (Note: you'll need to restart Atom after turning on react mode). |
