Automatically generate route name

[Dimitar5555]

🚀 feature request

Description

Currently PT routes will show only their ref if name is not present.

The screenshot is taken from https://www.openstreetmap.org/node/10744861347.

Describe the solution you'd like

Generating names like iD editor does it should work.

https://github.com/openstreetmap/iD/pull/8276/files

display_name:
      direction: "{direction}"
      from_to: "from {from} to {to}"
      from_to_via: "from {from} to {to} via {via}"
      network_direction: "{network} {direction}"
      network_from_to: "{network} from {from} to {to}"
      network_from_to_via: "{network} from {from} to {to} via {via}"
      ref: "{ref}"
      ref_direction: "{ref} {direction}"
      ref_from_to: "{ref} from {from} to {to}"
      ref_from_to_via: "{ref} from {from} to {to} via {via}"
      network_ref: "{network} {ref}"
      network_ref_direction: "{network} {ref} {direction}"
      network_ref_from_to: "{network} {ref} from {from} to {to}"
      network_ref_from_to_via: "{network} {ref} from {from} to {to} via {via}"

Describe alternatives you've considered

The only workaround is to add a name, but there is not much point in duplicating the data that is already available in machine readable format.

It's not clear in which order should we apply the rules:

display_name:
      direction: "{direction}"
      from_to: "from {from} to {to}"
      from_to_via: "from {from} to {to} via {via}"

In order they are mentionned they won't work as 3rd option wouldn't make sense as it will be always captured by 2nd option, may be they are applied in reverse order

[Dimitar5555]

I haven't noticed that detail. It should be fine if they are applied from the bottom to the top.

display_name:
      direction: "{direction}"
      from_to: "from {from} to {to}"
      from_to_via: "from {from} to {to} via {via}"
      network_direction: "{network} {direction}"
      network_from_to: "{network} from {from} to {to}"
      network_from_to_via: "{network} from {from} to {to} via {via}"
      ref: "{ref}"
      ref_direction: "{ref} {direction}"
      ref_from_to: "{ref} from {from} to {to}"
      ref_from_to_via: "{ref} from {from} to {to} via {via}"
      network_ref: "{network} {ref}"
      network_ref_direction: "{network} {ref} {direction}"
      network_ref_from_to: "{network} {ref} from {from} to {to}"
      network_ref_from_to_via: "{network} {ref} from {from} to {to} via {via}"

Summarizing rules following observations are:

1. {ref} is core, if it's present it will always show.
2. {from} to {to} via {via} or {direction} - will always show up if they are present. {from} {to} has more priority if {direction}
3. {network} will always append to the beginning if present

Name typically contains from / to, so we need to focus on examples when name is not present or not relevant
