Module: D:\lcc\inria\inria.h
Author: Jacob
Project:
State:
Creation Date: June 2001
Description: The user interface works as follows:
1: At startup it will look for the path to the
ocaml interpreter in the registry using the
key HKEY_CURRENT_USER\SOFTWARE\ocaml. If not
found will prompt the user.
2: It will start the ocaml interpreter with
its standard output and standard input
connected to two pipes in a dedicated thread.
3: It will open a window containing an edit
field. The output from the interpreter will be
shown in the edit field, and the input of the
user in the edit field will be sent to the
interpreter when the user types return.
4: Line editing is provided by moving to the
desired line with the arrows, then pressing
return; If we aren't in the last input line,
the input will be copied to the last line and
sent to the interpreter.
5: The GUI ensures that when we exit the ocaml
interpreter is stopped by sending the
character string "#quit;;\nCtrl-Z"
6: A history of all lines sent to the interpreter
is maintained in a simple linked list. The
History dialog box shows that, and allows the
user to choose a given input line.
7: Memory limits. The edit buffer can be of an
arbitrary length, i.e. maybe 7-8MB or more,
there are no fixed limits. The History list
will always grow too, so memory consumption
could be "high" after several days of
uninterrupted typing at the keyboard. For that
cases it is recommended to stop the GUI and
get some sleep...
9: The GUI will start a timer, looking 4 times a
second if the interpreter has written
something in the pipe. This is enough for most
applications.

own thread, its workings are independent of the rest
of the program. After starting the interpreter, the
thread waits in case the interpreter exits, for
instance if the user or some program types #quit;;.
In this case, the waiting thread awakens and exits
the user interface.

is supposed to be correct, no test for its validity
are done here.
