A simple viewer for logs in lsptrace format.

Example parsed viewer format looks like:

Usage

Install plugin mparq/lsptrace.

Setup creates the :LSPTraceView (ignore :LSPTraceShowFullLine for now, I don't know how to do plugins well) which you can run while viewing a .lsptrace file to open up a buffer from the contents of that file which contains a helpful, parsed representation of the lsptrace.

The plugin right now directly sets up the following maps:

• <TAB> when cursor is on a line to open up the full raw lsptrace message in a popup window. <TAB> again closes the window.
• q to exit the buffer.

Right now, I've only tested by viewing one buffer at a time, viewing multiple may break as the plugin manages a global state of trace lines.
