[fpc-devel] Dynamic GUI/Console apptype

Currently, programs for Windows have to be specified as either $APPTYPE
Console or GUI.
If the user runs a console-mode program from a console, the existing
console is kept; run outside a console, a new console is created.
If the user runs a GUI-mode program outside a console, no console is
created, and if run inside a console, the console is immediately released.
But suppose I want a program that will continue running in a console if
run from a console, but will not automatically create a new one if run
from outside a console. (Eg. without command-line arguments, launch the
program's GUI, otherwise print a list of valid arguments in the console.)
Would this be hard to implement? Presently I have to compile a
console-mode application, and use the Windows API call FreeConsole to
eliminate the console if it is not needed. This still makes a useless
console pop up for a moment, which looks silly. This could be as simple as
adding a check somewhere in the system unit for whether a console is
associated with the process or not, and decide the appropriate $APPTYPE at
As far as I can tell, this is an issue with FPC, but the feature request
was redirected for discussion here.
