This function validates a single hub config file against it's corresponding
schema.
Note that, for tasks.json
config files, validation is performed
in two stages:
Initial validation against the schema is performed using the
jsonvalidate
package which uses the"ajv"
(Another JSON Schema Validator) validation engine.If the initial validation is successful, additional dynamic validations are performed. This means that only after the initial validation passes, will any dynamic validation errors be detected.
Usage
validate_config(
hub_path = ".",
config = c("tasks", "admin"),
config_path = NULL,
schema_version = "from_config",
branch = "main"
)
Arguments
- hub_path
Path to a local hub directory.
- config
Name of config file to validate. One of
"tasks"
or"admin"
.- config_path
Defaults to
NULL
which assumes all config files are in thehub-config
directory in the root of hub directory. Argumentconfig_path
can be used to override default by providing a path to the config file to be validated.- schema_version
Character string specifying the json schema version to be used for validation. The default value
"from_config"
will use the version specified in theschema_version
property of the config file."latest"
will use the latest version available in the hubverse schemas repository. Alternatively, a specific version of a schema (e.g."v0.0.1"
) can be specified.- branch
The branch of the hubverse schemas repository from which to fetch schema. Defaults to
"main"
.
Value
Returns the result of validation. If validation is successful, will
return TRUE
. If any validation errors are detected, returns FALSE
with
details of errors appended as a data.frame to an errors
attribute.
To access
the errors table use attr(x, "errors")
where x
is the output of the function.
You can print a more concise and easier to view version of an errors table with
view_config_val_errors()
.
