I am trying to merge a bunch of my pascal units into a single unit, to avoid
circular references. This is quite a challenge because they are not all
compiled with the same mode.
Some units use {$Mode TP} And I can't compile some of the procedures from
that unit in other modes because I use features that only work in Turbo
Pascal mode, like modifying a for loop variable from inside the loop. I
also have issues with the curly brace { I can't use it as a literal
character like MyChar:='{'; because it thinks it's starting comment and
it's very strict in not allowing nested comments with curly braces like
this Case RunExt of { #134: {F12}
Thing1;}
#3: {Ctrl C}
Thing2;
End;
But then I have other procedures that just won't work in Turbo Pascal mode,
because I have used % to specify binary numbers like this:
My_Binary_Number := %10011001; and that just give me an error in Turbo Pascal
mode.. I could just change them to hex, but there are hundreds of them.
I'm wondering if there is some way that I can have some procedures compiled
with {$Mode FPC} and others with {$Mode TP}
I see something about {$ModeSwitch EXCEPTIONS} here:
https://wiki.freepascal.org/Compiler_Mode but I can't get that to work..
it doesn't say much about it... If I put that in I still can't change mode for
individual procedures.
You can't switch modes between procedure, because a mode implicitly alters the
uses clause, and for this reason can only occur before the uses clause.
Some mode-specific features can be switched on or off on a per-feature
basis, but this is not so for all features, and they are also global (i.e.
can be set only once for a unit).
Alternatively, is there any way to force it to allow circular unit references?
Only from interface to implementation.
If you have such a strange set of units, I would recommend a rewrite in each
case: it doesn't sound like a 'healthy' code base...
