New in version 5.0.

Functions

`guess_mimetype`(data)	Guess the MIME type of the given file content.
`match_mimetype`(pattern, test)	Return a score for how well the pattern matches the mimetype.
`parse_mimetype`(mime_type)	Parse a MIME type into its component parts.

Classes

MIMEType

A MIME type, parsed into its component parts.

class rbtools.utils.mimetypes.MIMEType[source]¶

Bases: TypedDict

A MIME type, parsed into its component parts.

New in version 5.0.

type: str¶

The full MIME type.

Type:: str

main_type: str¶

Main type (For example, “application” for “application/octet-stream”)

Type:: str

sub_type: str¶

Sub-type (for example, “plain” for “text/plain”).

This will include vendor information, if present.

Type:: str

vendor: str¶

The vendor tag, if available.

For example, “vnd.reviewboard.org.test” in “application/vnd.reviewboard.org.test+json”.

Type:: str

format: str¶

The sub-type format, if available.

For example, “json” in “application/vnd.reviewboard.org.test+json”.

Type:: str

__optional_keys__ = frozenset({})¶

__orig_bases__ = (<function TypedDict>,)¶

__required_keys__ = frozenset({'format', 'main_type', 'sub_type', 'type', 'vendor'})¶

__total__ = True¶

rbtools.utils.mimetypes.parse_mimetype(mime_type: str) → MIMEType[source]¶

Parse a MIME type into its component parts.

New in version 5.0.

Parameters:: mime_type (str) – The MIME type to parse.
Returns:: The type, parsed into its component parts.
Return type:: ParsedMIMEType
Raises:: ValueError – The given MIME type could not be parsed.

rbtools.utils.mimetypes.guess_mimetype(data: bytes) → str[source]¶

Guess the MIME type of the given file content.

New in version 5.0.

Parameters:: data (bytes) – The file content.
Returns:: The guessed MIME type.
Return type:: str

rbtools.utils.mimetypes.match_mimetype(pattern: MIMEType, test: MIMEType) → float[source]¶

Return a score for how well the pattern matches the mimetype.

This is an ordered list of precedence (_ indicates non-match):

Format	Precedence
`Type/Vendor+Subtype`	2.0
`Type/Subtype`	1.9
`Type/*`	1.8
`*/Vendor+Subtype`	1.7
`*/_ +Subtype`	1.6
`/`	1.5
`_`	0

New in version 5.0.

Parameters:

pattern (MIMEType) – A parsed mimetype pattern to score. This is a 3-tuple of the type, subtype, and parameters as returned by mimeparse.parse_mime_type(). This may include * wildcards.
test (MIMEType) – A parsed mimetype to match against the pattern. This is a 3-tuple of the type, subtype, and parameters as returned by mimeparse.parse_mime_type().

Returns:

The resulting score for the match.

Return type:

float
