ISSUES
1. [New comment] compile() does not recognize CO_FUTURE_PRINT_FUNCTION
http://ironpython.codeplex.com/workitem/35354
User jdhardy has commented on the issue:
"<p>Fixed in f064bdf.</p>"-----------------
2. [New issue] Installing a beta removes stable installation
http://ironpython.codeplex.com/workitem/35615
User MarkusSchaber has proposed the issue:
"Even though I chose a different installation directory when installing
IronPython 2.7.5b2, it did uninstall my stable 2.7.4 installation.
This should be changed that several IronPython installations can reside on the
same machine, as long as the user specifies different installation
directories."-----------------
3. [New comment] Installing a beta removes stable installation
http://ironpython.codeplex.com/workitem/35615

4. [New issue] ScriptSource.Execute returns null if expression is inside a
condition
http://ironpython.codeplex.com/workitem/35617
User kbranch38 has proposed the issue:
"I'm trying to use IronPython as an expression evaluator by hosting it from
.NET. After I discovered the SourceCodeKind.AutoDetect option, it works great
when the final statement is on its own, like this:
if True:
y = "True"
else:
y = "False"
y
ScriptSource.Execute will return "True" for the above, as expected. However,
this code will return null:
if True:
"True"
else:
"False"
This works as expected when entered into the IronPython interactive console,
just not when run from the .NET hosting side. The same seems to be true any
time the desired return value is inside another statement (a loop, function,
etc.).
Here's the hosting code (in VB.NET):
Dim engine As ScriptEngine = Python.CreateEngine()
Dim scope As ScriptScope = engine.CreateScope()
Dim source As ScriptSource = engine.CreateScriptSourceFromString(str,
SourceCodeKind.AutoDetect)
Dim result As Object = source.Execute(scope)
Is this a known limitation? Are there other options to achieve the same
result? I'm trying to make things as simple for the user as possible - the
alternatives I've found so far require a little more from them, like setting a
specific variable or using 'return' with their value."-----------------
5. [New comment] ScriptSource.Execute returns null if expression is inside a
condition
http://ironpython.codeplex.com/workitem/35617
User jdhardy has commented on the issue:
"<p>It's a limitation of the Python language. In Ruby, if blocks are actually
expressions and can have a return value like your example. In Python, they're
statements and have no value. I'm afraid it can't be done in Python the way you
want - the script writers will have to set a variable or use `return` or
`yield`.</p>"-----------------
6. [Status update] ScriptSource.Execute returns null if expression is inside a
condition
http://ironpython.codeplex.com/workitem/35617
User jdhardy has updated the issue:
Status has changed from Proposed to Closed with the following comment,
"If you have any further questions, please ask on StackOverflow or the mailing
list (http://ironpython.net/support/)."
