Hi,
this idea may need further refining, but it may be easier to handle
in Lazarus source editor, than in the compiler, where it was
originally posted.
In short, to have the nested try...finally/except...end; blocks display
in a single tier flatter manner, like
try
try
code block 1;
finally
code block 2;
end;
except
code block 3;
end;
display in Lazarus like
try
code block 1;
finally
code block 2;
except
code block 3;
end;
with similar handling like the collapsible code blocks (e.g. a [+] or [-] on
the gutter next to all the try's,
depending on what the default setting is, to display or not to display nested
try blocks)
and handling of more 'sophisticated' nests like
try...except...finally...except...end;
(that means, in raw source code, this still will display like nested try
blocks, not flat,
and as such be fed into the compiler).
This being handled in Lazarus would mean, that it would work in ANY compiler
mode selected
(regardless if it's Delphi or not) and the benefits of flatter display of the
code blocks
would really show (like making it harder to enter code blocks where they
normally don't go in such constructs,
and helping to catch errors made like that - e.g. if someone consciously needed
to put code in places it
does not normally go, collapsing the construct would not work).
It was met with resistance in the FPC mailing lists, and then it was dropped
there;
I can't say I don't agree with /some/ of their arguments actually.
Hope this would actually make more sense here :) as a coding tool.
Kind Regards
