Flex compiler shows some smarts
Developers like to compare IDEs. I use both Adobe Flex Builder 3 and Microsoft Visual Studio regularly. I think both are pretty good; each has its quirks and problems, perhaps Visual Studio marginally more than Flex Builder. One little thing I noticed while developing my Flex project today; Flex Builder compiler generates a warning when a single equal sign (=) is used in place of a double (==) for a equality comparison within a conditional statement. For example, the following statement:
if (x = y) {// do something }
will generate an compiler warning “Assignment within conditional statement (did you mean == instead of =?)”. I appreciated that. This is one of the most common syntax errors for programming newbies, and even us old hands fall prey to it on those late nights when the code is being churned out on autopilot. I think VS2008 would let this statement through the compile without batting an eyelid. Are there any other IDEs which pick up this very common syntax error?
