ahhhHAaaa... that makes sense in a way... why not use it in the LCL or

That would be great indeed, but Widget Type are complex beasts and
unfortunately they do not adhere to a common hierarchical structure but
due to their being created one by one "on demand" suffer from their
historical heritage, especially as I suppose the Windows Widget set has
been created first and same is the most "propriety" interface of all of
them.
A complete restructuring of all Widget Types seems to bee too much work
and risk to be considered viable.
something that would be like or take the place of the nogui one?
Not really, IMHO, a completely "headless" (no user interface) Widget Set
that allows for stuff like TTimer and Inter Process Event Queues is
viable, for embedded projects, too.
maybe even call it textGUI or some such?
The technical Term is TUI ("Text User Interface"). You also could use
TurboVision, as same is the base of what is provided with FPC
something that offers many of the same features as graphical GUIs but
in text mode?? ;)
Fell free to create this Widget Type. (Even though IMHO a restructuring
of the Widget Type Interfaces to introduce a decent hierarchy as a
container for all of them would be make creating new Widget Types a lot
easier) I'd be happy to test it :).
To start, I would take a look at FPGUI, as this Widget Type also does
not use external Widgets (like the Windows, KDE, Mac etc. Widget Types)
but creates it's own Widgets in Pascal code.

P.S.:
A decent hierarchy for Widget Type Interfaces might look like this:
- dummy (no functionality, just making projects compilable (this is
what NoGUI does)
- introducing exception handling (AFAIK, this is what the CGI Widget does)
- introducing TTimer and an inter thread events queue (this would
best done in FPC, but I fear they will not do so)
- introduce Widget set and a binding to a user interface either of
- create a Text based Widget set and link to input/output stream
for text (your idea)
- create a GUI Widget Set and link to "X" (FPGui)
- link to the KDE Widget Set implementation
- link to the QT Widget Set implementation
- link to the OSX Widget Set implementation
- link to the Windows Widget Set implementation
- link to FastCGI (with or without allowing for a HTML widget set
such as EXTJS) (just a dream :) )
- link to a remote Widget set connected via a byte stream (such as
TCP/IP) and implemented as a Lazarus Program running on a remote PC
(just another dream :) )
- ...
have fun :)
