Default Base Object

[just me]

The examples in the v2 docs don't run with v2.0-a076 and v2.0-a077 (Error: This line does not contain a recognized action). Is it intended?

[guest3456]

The default base may be accessed by using .base with any non-object value; for instance, "".base.

i guess the example "".base is no longer valid because of this:

Variable names cannot start with a digit and cannot contain the following characters which were previously allowed: @ # $. Only letters, numbers, underscore and non-ASCII characters are allowed.

changing "". to dummyvar. works, but then you run into the next issue:

Code: Select all

empty_var.foo := "bar"       ; <-------- no object to invoke

because of:

Error Handling

Expressions

An exception is thrown when any of the following failures occur (instead of ignoring the failure):

- An invocation fails because the target is not an object, or the method/property is not handled. For associative arrays, only a method call can cause this.

The examples in the v2 docs don't run

That is expected.

A great many examples have not been updated.
Topic: Documentation updated

"" is clearly not a variable.

It is not recognized as a standalone action because of a change to the way quotation marks are handled. Note that " ".base doesn't work in v1 either. The problem is only with detection of what kind of action the line contains, not parsing of the expression once it is recognized as such. The simple workaround is to use ("") or 0.

I was aware of the problem and hadn't planned to fix it, but maybe I will.

To avoid the exception, you just need to return value.

Thanks for the explanation.
