Follow links in requirement files named *.req.yml or *.req.yaml (for example satisfies: GRD-SYS-001) via click or Go to Definition.
The extension activates when you open YAML in a workspace whose root contains shallgraph.yaml or shallgraph.yml. Link navigation, Go to Definition, schema validation under requirements/, and the rendered view apply to *.req.yml and *.req.yaml files. Requirement YAML validation uses the YAML extension: on activation, ShallGraph registers the JSON Schema from core and refreshes it when shallgraph.yaml / shallgraph.yml or workspace folders change.
Rendered requirement view
Opening a *.req.yml or *.req.yaml file shows the YAML editor. A file may contain one requirement or several requirements separated by a line that contains only ---. With that file active, use the editor title Show Rendered View action (preview icon) to replace that tab with an HTML rendering of every requirement in the file. Show YAML Source switches the same tab back to the YAML editor. Links and Go to Definition resolve a requirement id to the file that contains it, including when that file's name is not the id.
The rendered view uses the same HTML as the exported requirements report. Edits belong in the YAML file. When that YAML changes while the rendered view is showing, the view refreshes. A requirement link in the rendered view opens the target requirement file as YAML. When the git origin remote is GitHub, file paths in the view are the same GitHub links as in the exported report.
