usdmanager.parsers.usd module¶
USD file parsers
-
class
usdmanager.parsers.usd.
UsdAsciiParser
(*args, **kwargs)[source]¶ Bases:
usdmanager.parser.AbstractExtParser
USD ASCII files.
Treat as plain text. This is the simplest of the Usd parsers, which other USD parsers should inherit from.

parse
(nativeAbsPath, fileInfo, link)[source]¶ Parse a file for links, generating a plain text version and HTML version of the file text.
Parameters: - nativeAbsPath : str
OS-native absolute file path
- fileInfo : QFileInfo
File info object
- link : QUrl
Full file path URL
-
parseLongLine
(line)[source]¶ Process a long line. Link parsing is skipped, and long USD arrays are truncated in the middle.
Parameters: - line : str
Line of text
Returns: Line of text
Rtype: str
-
parseMatch
(match, linkPath, nativeAbsPath, fileInfo)[source]¶ Parse a RegEx match of a path to another file.
Override for specific language parsing.
Parameters: - match
RegEx match object
- linkPath : str
Displayed file path matched by the RegEx
- nativeAbsPath : str
OS-native absolute file path for the file being parsed
- fileInfo : QFileInfo
File info object for the file being parsed
Returns: HTML link
Rtype: str
Raises ValueError: If path does not exist or cannot be resolved.

class
usdmanager.parsers.usd.
UsdCrateParser
(*args, **kwargs)[source]¶ Bases:
usdmanager.parsers.usd.UsdAsciiParser
Parse USD file assuming it is a crate file.
Don’t bother checking the fist line for PXR-USDC. If this is a valid ASCII USD file and not binary, but we use this parser accidentally, the file will load slower (since we do a usdcat conversion) but won’t break anything.
-
acceptsFile
(fileInfo, link)[source]¶ Accept .usdc files, or .usd files that do have a true binary query string value (i.e. .usd files we’ve already confirmed are crate).
Parameters: - fileInfo : QFileInfo
File info object
- link : QtCore.QUrl
Full URL, potentially with query string
-

class

UsdParser
(*args, **kwargs)[source]¶ Bases:
usdmanager.parsers.usd.UsdAsciiParser
Parse ambiguous USD files that may be ASCII or crate.
-
acceptsFile
(fileInfo, link)[source]¶ Accept .usd files that do not have a true binary query string in the URL (i.e. we haven’t yet opened this file to determine if it is crate, or we have checked and it wasn’t crate).
Parameters: - fileInfo : QFileInfo
File info object
- link : QtCore.QUrl
Full URL, potentially with query string
