Tests scrolling in processes_rows()
-----------------------------------
>>> from blessed import Terminal
>>> from pgactivity.types import *
>>> from pgactivity.views import *
>>> term = Terminal(force_styling=None)
>>> term.width
80
>>> processes_scroll = [
... RunningProcess(
... pid=x,
... application_name="pgbench",
... database="pgbench",
... user="postgres",
... client=None,
... state="active",
... query=f"SELECT {x}",
... encoding=None,
... duration=0.0,
... xmin=1234,
... wait=False,
... query_leader_pid=x,
... is_parallel_worker=False,
... ) for x in range(0, 10)]
>>> ui = UI.make(flag=Flag.PID|Flag.DATABASE)
>>> sproc = SelectableProcesses(processes_scroll)
>>> _ = sproc.focus_next()
>>> sproc.position()
0
>>> lc = line_counter(4)
>>> processes_rows(term, ui, sproc, lc.value, lines_counter=lc)
0 pgbench active SELECT 0
1 pgbench active SELECT 1
2 pgbench active SELECT 2
3 pgbench active SELECT 3
>>> for x in range(9):
... _ = sproc.focus_next()
>>> sproc.position()
9
>>> lc = line_counter(5)
>>> processes_rows(term, ui, sproc, lc.value, lines_counter=lc)
6 pgbench active SELECT 6
7 pgbench active SELECT 7
8 pgbench active SELECT 8
9 pgbench active SELECT 9
0 pgbench active SELECT 0
>>> _ = sproc.focus_next()
>>> sproc.position()

3 pgbench active SELECT 3
4 pgbench active SELECT 4
>>> for x in range(9):
... _ = sproc.focus_next()
>>> sproc.position()
9
We never put the focus on the lower 1/5th of the screen.
For 5 display lines, the focus will be on the 4th .
>>> lc = line_counter(5)
>>> processes_rows(term, ui, sproc, lc.value, lines_counter=lc)
6 pgbench active SELECT 6
7 pgbench active SELECT 7
8 pgbench active SELECT 8
9 pgbench active SELECT 9
0 pgbench active SELECT 0
For 10 display lines, it should be at 8th line.
>>> lc = line_counter(10)
>>> processes_rows(term, ui, sproc, lc.value, lines_counter=lc)
2 pgbench active SELECT 2
3 pgbench active SELECT 3
4 pgbench active SELECT 4
5 pgbench active SELECT 5
6 pgbench active SELECT 6
7 pgbench active SELECT 7
8 pgbench active SELECT 8
9 pgbench active SELECT 9
0 pgbench active SELECT 0
1 pgbench active SELECT 1
