Replace PreParse
As the PreParse page shows, PreParse
can be
used for a bunch of purposes.
Redrawing the screen
This version of PreParse
was written to accompany the more-elaborate
version of PrintStatusLine
on the
Replace PrintStatusLine page.
replace PreParse
{
! if the screen size has changed, we'll clear the screen,
! print the player's command, and redraw the status line before
! proceeding to interpret the command
if display.needs_repaint
{
! some text so transcripts aren't confusing when the player's
! input is listed twice
"[Detected screen size change; starting turn over...]"
cls
print prompt;
local i = 1, showfullstops
while word[i] ~= ""
{
print word[i];
if word[++i] ~= ""
print " ";
elseif word[++i] ~= ""
{
showfullstops = true
print ". ";
}
if word[i] = "" and showfullstops
{
print ".";
}
}
print ""
display.needs_repaint = false
PrintStatusLine
}
}
