Title: Message Title

Henrik Lindberg created an issue   Puppet / PUP-2288 access operation vs. liststart causes confusing errors... Issue Type: Improvement Assignee: Andy Parker Components: DSL Created: 16/Apr/14 7:22 PM Fix Versions: 3.6.0 Priority: Normal Reporter: Henrik Lindberg We have seen this issue before when a name is followed by a '[', there must be no space before the '[' to make it into an access operation, everywhere else that does not matter. This was however only fixed for NAME tokens. For everything else it does not matter how much whitespace there is between the preceding token and the LBRACK (even newlines), it is always an access operation. To work around this issue, you have to separate the list _expression_ from the preceding _expression_ by using SEMIC ':'. This is really annoying, and especially so when functions can be written in the Puppet Programming Language. e.g. function foo($x) { notice "Hello $x"} [mary, john].each |$name| { foo($name) } Has the effect that an error is raised for the function since it is only allowed to be defined in a non nested _expression_ (in the above it becomes the LHS of the [] _expression_! The way to fix this is always require that a LBRACK (for access) is placed next to the preceding token - e.g. these provides access: $a[0] some_func($x)[0] But not these: $a [0] # a variable dereference, followed by a list some_func($x) [0] # first the result of the function, then a list While experimenting, there is not a single test that is affected by this. Think this should be fixed for 3.6. since it will drive people trying out puppet functions nuts otherwise.
