When I select Filter Lines: Include ... (either string or regex) nothing happens with a large file

[bradlitterell]

When trying to filter a large file (6 million lines). nothing happens, I never get the opportunity to input a filter expression/string. I simply get dropped back in my 6 million line log file.

With smaller text files the extension seems to work, but inability to use it on large files defeats the purpose.

Hey @bradlitterell! The absence of a prompt window suggests that VS Code doesn't even get to executing the extension's code. The extension registers a text editor command, and VS Code needs to set up an editing context so that the extension could do its job. With 6 million lines, this preparatory work alone take too much time. I would say, such an amount warrants using separate tools rather than relying solely on an IDE...

Same behaviour here also with a rather big file (800.000 lines), in the output of extension host I get a warning:

2025-01-03 15:07:20.031 [warning] Cannot execute filterlines.includeLinesWithString because there is no active text editor.

If this is a limitation of VSC, the only thing I could dream of would be a notification instead of "nothing happens" :)

Apparently it is an old issue in VS Code...

Thanks for the reference. Closing this as not-planned.
