Filter Start Up

• Populate

Start up

• Need to make sure everything is closed before editing the filter file
  • If not galil will lock up
• Populate
  • Loaded filters
• Populate done
  • Nothing changed
• Read filters
  • Populated with past gall state filters
  • No buttons grayed when reading filters, could cause errors
  • Moving filter wheel
• Initialize
  • Populated with current filters
  • Moves through filters again

Important Notes

• #{} is string interpolation (substitution) like python {}.format
• hash is a dictionary like collection of keys and values
• stored in /usr/local/bin

Startup terminal output

• cannot open gui statefile
  • strange because it has no issue reading the lines of the state
  • I think the code is wrong there
    • should have a not (!)
• reads the state file
  • displays l + line of state file
  • displays read + GUI + state + line of state file

function readfwguistatefile

• reads file from location
  • /home/primefocus/fwgui.state
    • selectedfilter:none
    • initialized:yes
    • filterlist:g-u-z-i-r-bokr
    • loaded?:no
    • loadedfilter:none
    • filtersread:yes
    • loadedfiler:jammed
  • puts information into array $fwguistatehash

class Filter

• each line of the filter text is read into class Filter
• the line is split and assigned to magnet code, shortname, and filter color
• seems to create a hash of @filtercolor which is never used through the code
• also looking inside the filter text file, there is never supplied a filter color entered

Galil

• TCP Socket to localhost and server port
  • looks like serveraddress is not used function ogs (open galil socket)
• Creates a class Galil with telescope, instrument, server address, and server port
