mismatch between title variable and actual edm screen title for some motors

[KaushikMalapati]

Expected Behavior

motor-expert-screen should finish executing and move the screen to the cursor irrespective of the type of motor

Current Behavior

For certain types of motors including but not limited to pulsepickers, aerotechs, and smaracts, the variabel title will not match the actual title of the screen opened, resulting in xdotool search --sync hanging forever, the screen never being aligned to the cursor, and motor-expert-screen never completing.

Possible Solution

I think the way title is set should be changed. Instead of having on if-elif-else block to set the title, and another to open the screen, we should only have one block where we set the title variable and another variable containing the command that will open the screen. At the end of the block, xdotool search for old windows, then execute the command. This will make it easier to make sure each different type of screen correctly sets the title variable.

Steps to Reproduce (for bugs)

1. Run motor-expert-screen with a pv for a pulsepicker, aerotech, or smaract motor (XPP:SB2:MMS:29, XCS:SND:T1:Y1, or XPP:MCS2:01:m1 respectively)
2. Observe that motor-expert-screen never finishes executing, it just stays in the foreground until you manually terminate it, and that the screen is never moved to your mouse by xdotool.

Context

I noticed it while working on #233. I also feel like I've noticed this before but never paid it much attention.

Mismatches I have found so far

Type		PV			MES title	        actual title
PP	        XPP:SB2:MMS:29		Aerotech motor		IMS Motor Control
AeroTech  	XCS:SND:T1:Y1		Aerotech motor		SmarAct Motor Control
SmarAct		XPP:MCS2:01:m1		Aerotech motor		SmarAct Motor Control

How title variables are set (no fall through)

title
Newport XPS Positioner		rtyp == xps8p
IMS Motor Control -- Main	rtyp == ims
Typhos Suite - $(PREFIX)	rtyp == motor and caget "${PREFIX}:PLC:nErrorId_RBV"
Aerotech motor			rtyp = motor
IMS Motor Control -- Main	rtyp != motor and caget "$PREFIX.PN"
IMS Motor Control		rtyp != motor

How the screen is decided (also no fall through)

screen
typhos				rtyp == motor and caget "${PREFIX}:PLC:nErrorId_RBV"
xps8				rtyp == xps8p
mmc				rtyp == mmca
pcds_motion			rtyp == motor and caget "$PREFIX:PN"
mcs2_main			rtyp == motor and ($PREFIX == *"MCS2"* || $(caget "$PREFIX:PTYPE_RBV") and enc == *"Yes"*
mcs2_openloop			rtyp == motor and ($PREFIX == *"MCS2"* || $(caget "$PREFIX:PTYPE_RBV") and enc != *"Yes"*
aerotech			rtyp == motor
ims				rtyp != motor
