https://hermes.insa-strasbourg.fr/en/setup/configuration/plugins/attributes/regex_replace/ Description This plugin allows performing a replacement in a string using the specified regular expression. Configuration Nothing to configure for the plugin. hermes: plugins: attributes: regex_replace: Usage regex_replace(value: str, pattern: str, replacement: str, ignorecase: bool = False, multiline: bool = False, count: int = 0, mandatory_count: int = 0) → str As this plugin is just an adaptation of Ansible’s regex_replace_filter, you can also check its documentation. # Will be 'able' regex_result: "{{ 'ansible' | regex_replace('^a.*i(.*)$', 'a\\1') }}" # Will be '#CAR\n#tar\nfoo\n#bar\n' regex_result: "{{ 'CAR\ntar\nfoo\nbar\n' | regex_replace('^(.ar)$', '#\\1', multiline=True, ignorecase=True) }}" # It is possible to apply the method to a list of strings. Let's take LDAP_PASSWORD_HASHES, which contains a list of LDAP password hashes: # LDAP_PASSWORD_HASHES: # - "{SMD5}NGnIxNg+ZqB3XwhQK/jCRDWWpUQYVbwg" # - "{SSHA}9u8ZbEbeLPLI2f4isG7YjJsz6sfonjQAfbbadQ==" # - "{SSHA256}l0rZ10MhH6jKGogg2qFvCdiNAqkKVH9OuL0R3FgWRrV4mIaYM2cnYQ==" # - "{SSHA512}zKR46tmGg0NKq1FdkmLGZCqXqfnApvFRHSTW4H0Sem9zJH66mgZ6/aB/aypGX+dLAI02akd9lZbplX6y0Typzzir8RIKh6cw," # Remove the prefix inside the braces indicating the hash type. # regex_results: # - "NGnIxNg+ZqB3XwhQK/jCRDWWpUQYVbwg" # - "9u8ZbEbeLPLI2f4isG7YjJsz6sfonjQAfbbadQ==" # - "l0rZ10MhH6jKGogg2qFvCdiNAqkKVH9OuL0R3FgWRrV4mIaYM2cnYQ==" # - "zKR46tmGg0NKq1FdkmLGZCqXqfnApvFRHSTW4H0Sem9zJH66mgZ6/aB/aypGX+dLAI02akd9lZbplX6y0Typzzir8RIKh6cw," regex_results: "{{ LDAP_PASSWORD_HASHES | map('regex_replace', '^{[^}]+}(.*)$', '\\1') | list }}" Hugo en-US
