New submission from Sven Brauch <[email protected]>:
Hi,
I'm writing a python language support plugin for an IDE. I'm using the AST
module to get information about the loaded source code, which works pretty
well. However, in some cases, the information provided by the AST is simply not
sufficient to do proper highlighting (or whatever); for example,
class_instance.method(argument1.arg_attribute).attribute
class_instance.method( argument1. arg_attribute) . attribute
and
class_instance.method( argument1. \
arg_attribute) \
. attribute
produce exactly the same syntax tree, making it impossible to determine where
e.g. "attribute" starts and ends. Although technically obviously correct, the
information that the column offset for "attribute" is "0" is quite pointless.
It would really be great if there could be an additional attribute for
Attribute Access nodes which tells me where the attribute access the node
refers to *really* takes place, not just "column 0". :)
It would be even better if there was not only an offset, but also an "end"
attribute providing information on where the node ends; that'd make this module
way more useful, at least for me.
Thanks and best regards,
Sven
