In practice there will be limited communication between backend threads and the frontend console, I think I've managed to organise things so that there's effectively a single point of contact and the program will be able to run in text mode (i.e. inside something like GNU Screen) or with a GUI.

The basics are (now) rather clear to me: - The stuff needs to be appropriately integrated in the WidgetType selection mechanism Lazarus provides. - The stuff needs to be appropriately integrated in the Project Source mechanism Lazarus provides. - You need to do (at least) a TApplication class and a TTimer class - Any not GUI related stuff in TApplicartion should work as expected (.ExeName, Callback-events, QueueAsyncCall ) should work as expected - WakeMainThread needs to be implemented according to the OS we compile for. - After the initialization a main loop is executed that calls CheckSynchronize with an appropriate timeout (see below) - to do a really simple TTimer class my idea is: - - calculate the common denominator (but rounding to an appropriate minimum aka Granularity) of any instanciated TTimers' Time settings - - use that value as Timeout in CheckSynchronize. - - in the main loop, count a global timer and call TTimer Events as appropriate (if timer mod Timer[i].TimeSpec = 0, with Timer[i].TimeSpec := Timer[i].Time div Granularity) - - The Granularity should be a property the user can set.

[Lazarus] Getting and setting the x numbered word in a sentence
Hi, Is there an existing routine in Lazarus that will get and set effectively the x numbered word in a sentence without actually knowing what the actual word is? E.g with the string the cat sat on the mat You could say replace word 3 with string stood so the result would be a string which was the cat stood on the mat even though you didn't know that the 3rd word was originally sat?

It may be that without IPro the html version is just stripped of the

I don't appear to have turbopoweriprodsgn installed on any systems, and
removing the turbopoweripro package doesn't appear to change anything.
Possibly
CommentStr:=ExtractCommentContent(CommentCode.Source,CommentStart,
NestedComments,true,true,true);
if CommentStr '' then
Result:=Result+'span class=comment'+TextToHTML(CommentStr)
+' ('+SourcePosToFPDocHint(CodeXYPos^,'Source')+')'
+'/spanbr'+LineEnding;
etc. in ide/codehelp.pas. If so that gives me something to get my teeth
into.
