Properties
isInputOpen
Is an input line open? This is true between sending an <inputLine> event and either getting a reply, or explicitly sending a close or cancel event.
lastInput
the text of the last input line we received from the client
lastInputClient
client session who sent the last input line
lastInputReady
is input ready?
mode
Current UI mode. This is ‘working’ if the program is running and in the process of computing and/or generating output; ‘inputLine’ if we’re waiting for the user to enter a line of input; ‘morePrompt’ if we’re showing a “More” prompt.
moreMode
flag: we’re in More mode
outbuf
pending output buffer, since last flush
scrollback
Scrollback list. After each input, we add the contents of ‘textbuf’ to this list. If this pushes the list past the limit, we drop the oldest item. This is used to reconstruct a reasonable amount of scrollback history when a new client connects, or when an existing client refreshes the page.
scrollbackLimit
The scrollback limit, as a number of command inputs. Each input interaction adds one item to the scrollback list. When the number of items in the list exceeds the limit set here, we drop the oldest item.
srcOVERRIDDEN
no description available
textbuf
main window text buffer since last input read
vpathOVERRIDDEN
my virtual path, and the actual resource file location
Methods
cancelInputLine (reset)
Cancel an input line that was interrupted by a timeout
clearWindow ( )OVERRIDDEN
Clear the window
endMoreMode ( )
receive notification from the client that the user has responded to the More prompt, ending the pause
flushWin ( )OVERRIDDEN
Flush the buffers
getInputLine (timeout?)
Read a line of input in this window. Blocks until the reply is received. Returns nil on timeout.
getState (client)OVERRIDDEN
Get the state of this command window
receiveInput (req, query)
Receive input from the client
showMorePrompt ( )
Show a “More” prompt
textbufToScrollback (cmd)
Move the current text buffer contents to the scrollback list. If this would make the scrollback list exceed the limit, we’ll drop the oldest item.
‘cmd’ is the command line text of the last input. We include this in the srollback list with special tagging so that the UI can display it in a custom style, if it wants.
write (txt)OVERRIDDEN
Write to the window
