`validate_schema_description_new`(hed_entry)	Check the description of the entry for invalid character issues
`validate_schema_tag_new`(hed_entry)	Check tag entry for capitalization and illegal characters.
`validate_schema_term_new`(hed_entry[, hed_term])	Check the term for invalid character issues

get_allowed_characters(value_classes)[source]¶

Returns the allowed characters in a given container of value classes

Returns:: The set of all characters from the given classes
Return type:: character_set(set)

get_allowed_characters_by_name(character_set_names)[source]¶

Returns:: The set of all characters from the names
Return type:: character_set(set)

get_problem_indexes(validation_string, character_set, index_adj=0)[source]¶

Finds indexes with values not in character set

Parameters:

validation_string (str) – The string to check characters in
character_set (set) – the list of valid characters(or the value “nonascii” as a set entry)
index_adj (int) – the value to adjust the reported indices by, if this isn’t the start of a string.

Returns:

The list of problematic characters and indices

Return type:

index_list(tuple of (str, int))

schema_version_for_library(hed_schema, library_name)[source]¶

Given the library name and HED schema object, return the version

Parameters:

hed_schema (HedSchema) – the schema object
library_name (str or None) – The library name you’re interested in. “” for the standard schema.

Returns:

The version number of the given library name. Returns None if unknown library_name.

Return type:

version_number (str)

validate_schema_description_new(hed_entry)[source]¶

Check the description of the entry for invalid character issues

Parameters:: hed_entry (HedSchemaEntry) – A single schema entry
Returns:: A list of all invalid characters found in description. Each issue is a dictionary.
Return type:: list

validate_schema_tag_new(hed_entry)[source]¶

Check tag entry for capitalization and illegal characters.

Parameters:: hed_entry (HedTagEntry) – A single tag entry
Returns:: A list of all formatting issues found in the term. Each issue is a dictionary.
Return type:: list

validate_schema_term_new(hed_entry, hed_term=None)[source]¶

Check the term for invalid character issues

Parameters:

Returns:

A list of all formatting issues found in the term. Each issue is a dictionary.
