Create baseline

Write a baseline file for a selection (SR-050, ADR-0018): name, date, the HEAD commit of every repository involved, ID and version of every element. Refused while files of the selection are not committed. Never commits, never replaces a baseline.

Command baseline.create. Writes files in the working tree, never to Git. It is refused while the workspace is read-only. Stores the current versions of the selection, which depend on the metamodel (which properties count).

Input

Field	Type	Required	Description
`name`	`name`	yes	Name of a baseline (SR-050), unique in the workspace ignoring case and Unicode normal form. The file name is the name made portable, as attachment names (ADR-0004); a taken file name gets -2, -3, ….
`selection`	`selection`	yes	Stored in the file: a saved filter as its where and view, package and view with their title. Not baseline.

Output

Field	Type	Required	Description
`files`	array of `string`	yes
`baseline`	`object`	yes
`baseline.name`	`string`	yes
`baseline.file`	`string`	yes	The file, relative to the workspace root, / as separator.
`baseline.repository`	`string`	yes	The repository that holds the file; `repository` in the file is relative to it.
`baseline.date`	`dateTime`	yes	A date and time with time zone (RFC 3339 date-time), for example 2026-10-26T09:30:00Z.
`baseline.elements`	`integer`	yes	Number of elements in the file.
`problems`	array of `problem`	no
`incomplete`	`incomplete`	no	A repository is not here, so the view may miss a replacement or exclusion stored there (SR-006); the file is written all the same, with a warning.

App

In the command prompt (Ctrl+Shift+P, macOS ⌘⇧P): the command Create baseline.

baseline.

Options:
  --name <value>          instead of the argument <name>
  --input <json|@file|->  command input as JSON: inline, from a file, or from
                          standard input
  --workspace <path>      workspace root (default: nearest folder upwards with
                          reqseq-workspace.yaml)
  --json                  print exactly the command output as JSON
  --yaml                  print the whole command output as YAML, problems one
                          per line
  -h, --help              show help

Only via --input: selection
