I've at least once gotten an error "whileRunning is not a function" at server.js:40, though I can't seem to reproduce it

if the edge doesn't have any characters and the user clicks "update", an error message should appear rather than deleting the edge

From Kevin:

I have no idea what the 'end' button does. It's possible these buttons conceptually map to "start" / "step" / "stop"; if so, those are the more usual names.

When I click '+', I can't find the "☐" very easily.

Error from console:

TypeError: undefined is not a function (evaluating 'names[i].endsWith ("@stanford.edu")')

I've tested Chrome, and submit functionality works fine. We should test Firefox as well.

Use Max's example:
https://web.stanford.edu/class/cs103/cgi-bin/restricted/tm.html?saved=asdf

Jay, I need an interface for showing the message. Thanks!

From Kevin:

"Force directed layout" gives "Uncaught TypeError: gTopMenu.forcedDirectedLayout is not a function"

Low priority. We could also take out this feature.

Kevin:
If you enter a test string which uses characters which are not in the alphabet and then 'run' then 'step' over such a character, it silently fails with " Uncaught TypeError: Cannot read property '0' of undefined gDFASimulator.step @ dfa.js:7 gTape.step @ tape.js:71 gTestMenu.step @ test.js:75 "

Kevin:

If a node was marked as the current node as part of a test, and then you load a saved automata, the little red halo remains where it was.

Seems to be an issue on my laptop?

There's no way to see the alphabet while working on a problem

There should be some message to the user when the browser is getting the list of saved automatas from the user.

I can use all of the buttons except save and load, which freeze the screen when I click. There are no console errors. My guess is that the modal appears somewhere off the screen.

from Kevin:

There's no indication that the machine you've entered is not a DFA (eg, missing edges)

It looks like it might require tspans inside text tags.

I'd suggest having two radio buttons or a switch for left and right rather than having to type in "L" or "R". Here are some ideas: http://www.google.com/design/spec/components/switches.html#switches-radio-button

From Kevin:
There is no indication that the machine is not running (eg, if you enter a string, run, then change the string, it looks like it's ready to go [or has already processed some characters], but won't actually do anything until you hit "run"). I would expect hitting 'enter' after entering a string would reset the machine such that hitting 'step' causes it to step through that string from the beginning, starting at the start state.

From Kevin:

The testing bar at the bottom highlights the character it's going to process next. This is a bit pedantic, but I would expect a highlighted character to be one which is currently being processed (so maybe highlighting an edge? not that this is an important feature), not one which is about to be processed. I think it's a lot clearer to have the cursor being between characters rather than over a particular one.

Questions to answer:

• Are there trailing and preceding "☐" characters in the main string?
• What if the tape head ends on a blank space before the beginning of the string?

Kevin:

Actually submitting leaves the button saying "Submitting..." seemingly forever; I can't tell if it actual submits or not (though the console shows an XMLHTTPResponse)

From my own testing: No error message appears in the console. Possibly server side error.

Enter nothing, only set initial state, st:
