Multiline support

[Tolriq]

We discussed this in another thread, but in the logs I need to analyze today this is problematic.

Currently there's no support for multi line log lines, this means that the other lines have no date / log level and tag.

Meaning all you can do is eventually filter them out via -^$ but it will filter all of them and in my case I need to keep some and remove all the very verbose others and there's no way to achieve that.

Would be nice if the message part supported multiline and the other lines were added to the previous message or if the date/level and tags where at least copied from the previous line to allow filtering (A little less good as it would probably add those extra data when copy pasting).

Rendering multiline text in Swing can be challenging because it requires variable renderer heights, leading to remeasurement during rendering, which affects performance. Additionally, in the current log-processing workflow, content is split into lines, and any log message containing a line break is treated as a new line.

Never said it would be easy, but still nice to have.

From a quick look of all usages, the LogParser.parse() could be extended to pass a previousLine: String? to handle those lines without too much changes.

The other solution is to extend the LogParser interface with a sequenceFilter that is added between the first sequence generation and the actual parser calls. This allows to merge lines back together via for example a regexp that if not matching merge with previous line if there's one. Even if the GUI does not show all the lines we can see them via double click and copy paste.

As a quick solution on my side I went the second way Tolriq@dce0769

Nice solution for your problem.It will be better to make it configurable.

[Tolriq]

Yes but I have 0 knowledge of the swingui part for that.

Should be part of the logParserInterface with optional step configurable in log parser configuration.

So if you are interested would be nice, else I'll keep it as an hack for now, I doubt I'll have time to learn all the UI aspect just for this :(
