you can wrap any Expression in an ExpressionStatement and get what you need

m = [|
def method(bar as string):
baz = bar
e = [| foo = bar |] // a BinaryExpression
s = ExpressionStatement(e)
m.Body.Statements.Add(s)

And yes, working with code generation via macros is challenging, and

I was misreading the error. I need a Statement, not an Expression.
This is really where I have so many issues composing methods with
Template Macros; getting Statements. Here's what I wrote, just s/
expression/statement/i it:

In general, I seem to have a lot of issues composing methods out of

Building Methods: Finding Expressions from Template Macros

rekt...@gmail.com (rektide) — Tue, 24 Nov 2009 20:38:48 UT

I'm doing some significant class generating code in boo. I seem to
have a lot of problem using Template Macros to build Expressions.

Here's a snippet of something I'm attempting:

ser = [|
def Serialize() as (byte):
pos = 0
....
ser.Body.Statements.Add( [| $(ReferenceExpression("ser"+i) ) =

oh I'm very sorry guys, I solved the issue but I didn't post yet, so
here is what I wrote in TomBoy to remember the solution:

From my experience it seems just a "nant rebuild" might suffice for some
weird reason.
Of course needs to be fixed anyways.

Yeah. That sucks.

You have to remove your old boo libraries from the GAC before building
the new version for now:

for m in Boo.Lang Boo.Lang.Compiler Boo.Lang.CodeDom
Boo.Lang.Parser Boo.Lang.Useful Boo.Lang.Interpreter
Boo.Lang.Extensions;
do sudo gacutil /u $m;
done

I have mono from trunk and latest boo source (boo-0.9.2.3383-src.zip)
when compiling:
"$ nant", I get the following error:

You might have to add a reference to the Boo.Lang.Extensions assembly...

Problem with "using" macro

eranth...@gmail.com (RickA) — Wed, 18 Nov 2009 19:22:28 UT

I just downloaded the latest version of SharpDevelop (3.1). When I
compile some older code it throws an unknown identifier error on the
"using" macro. Offending code below:

def email(subject as string, body as string):
if len(_smtp_from) > 0 and len(_smtp_to) > 0:
using smtp = SmtpClient(_smtp_ip):

Hi madic77,
I doubt the Rhino.DSL really needs Boo.Land and Boo.Lang.Compiler. If it
does, you should use something else instead (or please your provider to
install Boo implementation on his system :D ).

Boo for Silverlight

trus...@gmail.com (madic77) — Tue, 17 Nov 2009 17:04:24 UT

Hi, dear All!

In my Silverlight application I'm trying to implement DSL which will
manage user interface. I want to use Rhino.DSL. So I need to build
Rhino.DSL libraries for Silverlight. As far as I can see the only
issue is that Rhino.DSL references Boo.Lang, Boo.Lang.Compiler,
Boo.Lang.Parser.

unable to access a private field of an instance passed to a static method

simon.pl...@googlemail.com (psi) — Fri, 13 Nov 2009 21:09:49 UT

recently i tried turning a class generic, and found i couldn't access
a private field of an instance passed to a static method any more.

(also why is the error for a field signature of 'c2[of c2[of
T].T]._f1' and not just 'c2[of T]._f1')

class c1():
private _f1 as int = 1
static def m1(c as c1):

horac...@gmail.com (horace grant) — Thu, 12 Nov 2009 00:27:22 UT

my _FLOAT function (which is defined elsewhere - not in the macro file
but in the project where the macro will get used) converts from a
fixed point format to floating point.

def _FLOAT(v as int) as single:
return cast(single, v) / (1 << 10)

thanks! i will try this again once i continue working on my wrapper project...
