Kate ,Kwrite gets real slow with minified file (wraped lines) like in jquery.min.js I haven't tried it on other file types other than js.
it consumes much cpu time and the whole program seems to hang.

Reproducible: Always

Steps to Reproduce:
1.open kate
2.open a js minified file
Actual Results:  
gets real slow when moving cursor or making search.

Expected Results:  
function properly.

Please explain what you mean by minified file. Is it that the entire contents is in one single line?

The minified file contains no Enter special char (#13) Tab char (#27) among others

Comment 4 Christoph Cullmann 2014-09-22 20:29:51 UTC

For that, we have the "line length limit" on load.
this is unfixable, as layouting long lines is just slow with Qt, even with Qt 5.
Minified files are not there for editing, for viewing, it works just fine, with the line length limit.

or you can try this free online js minifier http://www.online-code.net/minify-js.html,
I used this free tool for a long time.
