= SWHID inline macro extension
:toc:


An inline macro for easily linking link:https://docs.softwareheritage.org/devel/swh-model/persistent-identifiers.html[SWHIDs].


== Synopsis

[source, asciidoc]
----
swh:$SWHID[$CAPTION]
----

If no caption is given, the link text will be the core identifier of the SWHID.


== Attributes

You can configure certain behavior of the macro with the link:https://docs.asciidoctor.org/asciidoc/latest/attributes/options/[options attribute].
Here's a list of them...

- `full` will make the entire SWHID as the default link text.


== Extra notes

You would use like in the following form `swh:swh:1:snp:6ea7d28dfd4789609e0be2b64179fc9c12931beb[]` but you could also cut off `swh:` from the SWHID if you want to (i.e., `swh:1:snp:6ea7d28dfd4789609e0be2b64179fc9c12931beb[]`) to make it aesthetically pleasing.

Whatever your preference is, the best practice for dealing with linking SWHIDs with this macro is setting attributes containing the SWHIDs.

== Example usage

This should work with the following types of SWHIDs.

- A SWHID with only the core identifier: `swh:1:snp:6ea7d28dfd4789609e0be2b64179fc9c12931beb[]`.

- A SWHID with only one qualifier with a link caption: `swh:1:cnt:ce4dd1988d2d5dfcec48252757a6fea94339ac38;lines=3-4[some code text]`

- A SWHID with full contextual information.
This is as depicted from the recommended practice for writings (i.e., blog posts, technical documentation, research papers) when referring to one of the objects in the archive.
