SqlLine integration #17

Open snuyanzin opened 5 years ago

snuyanzin commented 5 years ago

The PR suggests initial integration with SqlLine mentioned at #9. Some sqlline commands are hidden, especially for mat-calcite-plugin there is added !open_dump Short demo how it currently looks like https://asciinema.org/a/251789, https://asciinema.org/a/251617

Startup: ./MemoryAnalyzer -application MatCalcitePlugin.execute sqlline

The issue which I currently faced is that it looks like jna/jansi could not handle ctrl-c correctly in eclipse env... It leads to endless loop. Right now I do not see any way to cope with it without changes in third party (at least sqlline)

I tried with MAT 1.10.0 + Sqlline 1.9.0 + macOS, and it seems to work (including ctrl+c)

just checked: for me it is still reproducing. It seems Linux specific. Based on trace jline3 uses System specific pty (in my case LinuxNativePty). I suppose that could be a reason why on macOS it could work
