How line numbers can be off in js debugger.

A user filed issue 246 with Firebug including an example that explains
at least some of the problems I have had with line numbers from JSD. Script tags like: <script language="javascript" type="text/javascript" src="foo.js"></script> <script language="javascript" type="text/javascript" src="bar.js"></script> cause the line numbers from JSD to be off by 4 lines. I guess (6 - 2) = 4, 6 original lines and 2 compressed lines. If I use 12 lines in 4 script inclusions I get 8 line offset: (12-4)= 8. But I can't figure out the direction: JSD gets larger line numbers, not smaller as I would guess. Also a workaround will need some work... Affects both Venkman and Firebug. Test case: http://fireclipse.svn.sourceforge.net/viewvc/*checkout*/fireclipse/trunk/FireclipseTests/WebContent/issue246badForDebugging.html John. _______________________________________________ dev-apps-js-debugger mailing list dev-apps-js-debugger@... https://lists.mozilla.org/listinfo/dev-apps-js-debugger |

Could you file a bug on this on bugzilla.m.o ? It's a bit of a shame that there's no possibility to distinction engine bugs from venkman bugs, but it'd still be nice to have this filed. Thanks! ~ Gijs PS: In a hurry now, so I haven't spent any time looking up causes/solutions/whatevers - but if we want this fixed in jsd we need to be pretty quick... _______________________________________________ dev-apps-js-debugger mailing list dev-apps-js-debugger@... https://lists.mozilla.org/listinfo/dev-apps-js-debugger |
