no-missing-description-on-validation-rules.ts	Checks that the "Description" field is populated on validation rules.
description-min-length-on-objects.ts	Checks that the "Description" field on custom objects meets a minimum length.
description-min-length-on-fields.ts	Checks that the "Description" field on custom fields meets a minimum length.
description-min-length-on-flows.ts	Checks that the "Description" field on flows meets a minimum length.
description-min-length-on-validation-rules.ts	Checks that the "Description" field on validation rules meets a minimum length.
error-message-min-length-on-validation-rules.ts	Checks that the "Error Message" field on validation rules meets a minimum length.

no-prefix-on-metadata.ts	Blocks a given prefix on API names of metadata.
no-double-spaces-in-picklist-fields.ts	Checks for unintended double spaces in picklist labels and values.

Config

Configuring which rules run, their level and other options, is managed via a config file that is passed into the linter when executing.

An example config file is available in this repo: https://github.com/tomcarman/sf-metadata-linter/blob/main/example/config.yaml

Global Settings

Name	Description	Example
csvFilename	The name of the file when outputting to CSV.	results.csv
sarifFilename	The name of the file when outputting to SARIF.	results.sarif
parentDirectory	This is the path above the specific metadata folders (eg. classes, flows, objects etc). If supplied, it will strip this from the results when rending the CLI table (saving space).	force-app/main/default/

Example

config:
  csvFilename: results.csv
  sarifFilename: results.sarif
  parentDirectory: force-app/main/default/

Rule Settings

All rules support the following:

Name	Description	Example
active	(boolean) Controls if the rule is run or not.	true or false
level	(enum) The level of the rule.	info, warning, or error

Example

rules:
  - name: no-missing-description-on-fields
    active: true
    level: warning

Rule Options

Some rules can be customised with additional options, see the rule documentation for further information.

Example

  - name: description-min-length-on-fields
    active: true
    level: warning
    options:
      - name: minimumLength
        value: 100

Output formats

Different output formats are available for the results, defined by the --format flag.

Table

• This is the default output format and what is used when no other format is supplied.
• Not all fields are included (eg. rule full description) in order to save space.

SARIF

• SARIF (Static Analysis Results Interchange Format) is standardised format for static analysis tools.
• It's supported by various DevOps tools - eg. GitHub, Azure DevOps.
• The SARIF output can be used when running the linter as part of CI/CD pipelines. The results can be shown inline in pull requests.

CSV

• Results can be outputted to a CSV - useful for one-off audits etc.
