Greg, using
inputline = gets(0) return inputlinethe input line stops at the end of the first screen row at the right side. If column count is 80, i can enter the 80th character, but the cursor stays at the 80th column as well. This is using eui or euiw , version Euphoria-10-Feb-2013 (the last stable release i am aware of).
However, using
-- get user text typed or pasted to input region at bottom of console window
-- test is echoed to screen as it's typed
-- 4 lines max, and only [backspace] is working
function get_text()
sequence inputline = ""
integer colflag = 0
while 1 do
--trace(1)
integer n = get_key()
if n != -1 then
if find(n,{10,13}) -- [enter]
then return inputline
else if equal(n,8) -- 8 = [backspace]
then
junk = get_position()
if not equal(junk[2],1) then
position(junk[1],junk[2]-1)
puts(1,' ')
position(junk[1],junk[2]-1)
inputline = inputline[1..$-1]
end if
if equal(junk[2],1) then
position(junk[1]-1,col_count)
puts(1,' ')
position(junk[1]-1,col_count)
inputline = inputline[1..$-1]
end if
else
inputline &= n
if (length(inputline) > (4*col_count)-2) then return inputline end if
junk = get_position()
if equal(junk[2],col_count) then colflag = 1 end if
position(row_count-3,1)
puts(1,inputline)
if colflag then
position(junk[1]+1,1)
colflag = 0
end if
end if
end if
end if
sleep(0)
end while
return ""
end function --get_text()
-- cursor go left = 1016384
-- cursor go right = 1016416
i can enter 4 screenlines 80 chars wide, and most likely as many screen lines as i want. But i also don't have mouse or cursor controls. I also coded a backspace function (ASerpa's Bug Ticket #915), as you can see, and i should recode the if-stack as a case-stack. I'm not really looking for much as a gui (it's only an irc bot interface, not a real client), but i did expect as much as i find in a dos console window, like when doing a netstat or wget or dir or mogrify operation.
