This release fixes a bug with parsing negative numbers (#385): before, -10 would be parsed as (minus, number) whereas
right now it's going to be parsed as (number) only.
This fixes a bug with precedences, where -1.str() would be parsed as (-, (1, str)), leading to first calling the str method on the positive number, then applying the minus.
Before:
⧐ -1.234.str()
ERROR: unknown operator: -STRING
[1:1] -1.234.str()
After:
⧐ -1.234.str()
-1.234
If a space is found between the minus and the number, the old parsing mechanism still applies.
It's inspired by Ruby, where:
$ - 1.to_s()
-@: undefined method `-@' for "1":String
$-1.to_s()
-1
$ -10.3.floor()
-11
$ - 10.3.floor()
-10
In addition, the documentation for strings has been improved (#384).
Thanks to @gromgit both for finding the bug as well as improving the documentation ❤️
