How does ''surround'' work?

#1 08-06-2008, 12:02 PM

I have this three indented lines:

for i := 1 to 10 do begin
DoSomething;
end {for};

If I select them, and right-click ''surround tryf'', I get this:

try
for i := 1 to 10 do begin
DoSomething;
end {for};

finally
end;

The selected code indentation is increased, which is correct, but the
try/finally/end is not indented at the former code indentation. Is that the
intended behaviour?

I would have expected this:

try
for i := 1 to 10 do begin
DoSomething;
end {for};
finally
end;

The resulting alignment is a bit random <g>, the template engine is not
quite up to the task here. If you select comlete lines you get what you
observered, with the try..finally positioned in column 0. If you start
the selection on the "f" of the for and extend it to the semicolon
after the end comment you get something a bit closer to what one would
expect: the finally end is aligned on the old column of the for but the
try ends up directly above the for, so one indentation level to far to
the right.

As Peter mentioned : " The resulting alignment is a bit random "

If you want better surround templates, check ModelMaker Code Explorer:
http://www.modelmakertools.com/code-explorer/index.html

This allows controlling the indent per template (and even unindent the template)
allows surrounds in a single line (FreeAndNil(..), Format(...)
and has two dedicated surrounds:

try finally wizard: this inserts finalization code based on the code before try.
block wizard: this surrounds a selection with a beginend bloc, determining
the indent automatically.

Both and several other "minor" features are demo-ed in this movie:

The try finally wizard is at about 3/4...
