add dot command for views

[zachvalenta]

Description

I use the .tables command a lot and occurred to me it might be useful to have one for views as well. I'd use it at least!

@amjith It occurs to me - if the premise of this PR is accepted - there's likely some doc changes that need to be made. Happy to chip in there as well, just lemme know.

[amjith]

Could you add a test for this? Here's a good candidate test you can use as reference.

BTW, I like the PR I do plan on merging this once I get a chance to try it out locally.

[zachvalenta]

Sounds good on both counts! Will do it over the weekend if that works.

I tried the branch in my local db and works as expected. Here is the output

Is there a specific reason to ignore views with prefix sqlite_? Do you happen to know when these(sqlite_xxx) views are created?

[amjith]

I believe this query is a modified version of the tables_query in sqlexecute.py. SQLite will create temporary tables for query planning purposes such as sqlite_stat*. I don't think it is applicable to views.

[amjith]

Merging this now. I can add tests for it.
