Pref::postInput
-- actions
after inputWith Pref::postInput
, actions directly after the data
input can be initiated.

- | function to be executed after data input |
the previously defined function

,
Pref::promptString
Pref::postInput
a function can be defined to
initiate actions after ending every complete input line with
<RETURN>
.Pref::postInput
in joint with Pref::promptString
und Pref::postOutput
can be used
to create status informations about evaluation. Possibilities are
informations to time, memory usage, types of results etc. (see Pref::postOutput
)Pref::postInput
without arguments will
return the current value. The argument NIL
will reset the
default value, which is NIL
.Pref::postInput
will be used to numerate
the input lines in joint with Pref::promptString
. The global
variable NumberOfLine
must be initialized with
0
. This all can be done in the file
``userinit.mu
''.
>> NumberOfLine:= 0: Prompt:= Pref::promptString(): Pref::postInput(proc() begin NumberOfLine:= NumberOfLine + 1; Pref::promptString(expr2text(NumberOfLine) . Prompt) end_proc):
Time mesure in seconds.
>> Pref::postInput(() -> (TIME:= time())): Pref::postOutput(proc() local Time; begin Time:= trunc((time() - TIME)/1000); stringlib::format("Time: ".expr2text(Time)." s", TEXTWIDTH, Right) end_proc): T:= time(): while time() - T < 1000 do null() end_while
Time: 2 s
The output depends on the value of the variable TEXTWIDTH
.
