_loader/types: Compute provenance directly in 'Dependency'

2019-06-26T16:29:15+00:00

Merge branch 'bschubert/node-api-noget' into 'bschubert/new-node-api'

2019-06-26T14:11:52+00:00

introduce a Node api, and remove node_get

_yaml: Add a 'get_node' on Mapping, when return type can be of multiple types

2019-06-25T20:09:41+00:00

Sometimes, we might want to have a list or a string, in which case, we
can now use 'get_node', which can return multiple types.

This method doesn't contain a 'default' value, as building a 'Node' from
it would be hard. We therefore just have a 'allow_none' flag that allows
returning 'None' when the value is not found.

- includes: use the new 'get_node' instead of trying multiple versions

_yaml: Never create base 'Node' directly

2019-06-25T20:09:41+00:00

We shouldn't have to create normal nodes ever. Let's ensure we don't

_yaml: Remove 'node_get' and migrate all remaining calls to new API

doc/bst2html: Remove usage of 'node_get' and use new API

2019-06-25T20:08:50+00:00

element: Remove `node_get_member` and all references to it

2019-06-25T20:08:50+00:00

This can now be done more easily with the Node api

plugin: remove 'node_get_list_element'

2019-06-25T20:08:50+00:00

The new yaml API is able of getting these access with the same error
messages handling.

Having this helper is therefore not useful anymore.

element: remove 'node_subst_list_element'

2019-06-25T20:08:50+00:00

This method is unused and can be easily reimplemented with the new
Node API by looping over nodes.

tests: remove 'node_get_yaml_provenance()' helper and replace with the new API

2019-06-25T20:08:50+00:00

This function is hard to make generic and, with the new API, the access
is simplified. Therefore, removing this function and migrating all its
usages
