Suffix:

.zip

Support:

✅ Full

Example:

from scfile import formats

with formats.zip.TexarrEncoder(data) as zip:
    zip.encode().save("output.zip")

Encoder#

class TexarrEncoder(data, options=None, output=None)[source]#

Bases: FileEncoder[TexarrContent]

format: FileFormat = 'zip'#

Associated file format.

order: ByteOrder = '<'#

Default byte order for pack/unpack operations.

serialize()[source]#

Write self.data to the output stream. Called by encode().

add_signature()#

Write the format signature to the output stream.

Return type:

None

close()#

Flush and close the IO object.

This method has no effect if the file is already closed.

Return type:

None

property closed: bool#
encode(transforms=None)#

Runs encoding pipeline.

Parameters:

transforms (Optional[list[Callable[[ModelScene], ModelScene]]]) – Override the default transforms for this call.

Return type:

Self

Returns:

Self (chaining).

export(path, mode='wb')#

Write encoded data to file by stem. Format suffix appended. Closes encoder.

Parameters:

  • path (str | Path | PathLike[str]) – Output file path.

  • mode (Literal['rb', 'rb+', 'wb', 'wb+', 'ab', 'ab+']) – File mode (binary).

Return type:

None

export_as(path, mode='wb')#

Write encoded data to file by stem. Format suffix appended. Keeps the encoder open.

Parameters:

  • path (str | Path | PathLike[str]) – Output file path.

  • mode (Literal['rb', 'rb+', 'wb', 'wb+', 'ab', 'ab+']) – File mode (binary).

Return type:

Self

fileno()#

Returns underlying file descriptor if one exists.

OSError is raised if the IO object does not use a file descriptor.

flush()#

Flush write buffers, if applicable.

This is not implemented for read-only and non-blocking streams.

Return type:

None

getvalue()#
Return type:

bytes

is_eof()#
Return type:

bool

isatty()#

Return whether this is an ‘interactive’ stream.

Return False if it can’t be determined.

property location: str#
prelude()#

Hook called before transforms, signature and serialization.

Return type:

None

read(size=-1)#
Return type:

bytes

readable()#

Return whether object was opened for reading.

If False, read() will raise OSError.

Return type:

bool

readline(size=-1, /)#

Read and return a line from the stream.

If size is specified, at most size bytes will be read.

The line terminator is always b’n’ for binary files; for text files, the newlines argument to open can be used to select the line terminator(s) recognized.

readlines(hint=-1, /)#

Return a list of lines from the stream.

hint can be specified to control the number of lines read: no more lines will be read if the total size (in bytes/characters) of all lines so far exceeds hint.

save(path, mode='wb')#

Write encoded data to file by name. Closes encoder.

Parameters:

  • path (str | Path | PathLike[str]) – Output file path.

  • mode (Literal['rb', 'rb+', 'wb', 'wb+', 'ab', 'ab+']) – File mode (binary).

Return type:

None

save_as(path, mode='wb')#

Write encoded data to file by name. Keeps encoder open.

Parameters:

  • path (str | Path | PathLike[str]) – Output file path.

  • mode (Literal['rb', 'rb+', 'wb', 'wb+', 'ab', 'ab+']) – File mode (binary).

Return type:

Self

seek(pos, whence=0)#

Change the stream position to the given byte offset.

offset

The stream position, relative to ‘whence’.

whence

The relative position to seek from.

The offset is interpreted relative to the position indicated by whence. Values for whence are:

  • os.SEEK_SET or 0 – start of stream (the default); offset should be zero or positive

  • os.SEEK_CUR or 1 – current stream position; offset may be negative

  • os.SEEK_END or 2 – end of stream; offset is usually negative

Return the new absolute position.

Return type:

int

seekable()#

Return whether object supports random access.

If False, seek(), tell() and truncate() will raise OSError. This method may need to do a test seek().

Return type:

bool

signature: Optional[bytes] = None#

Expected file signature.

size()#
Return type:

int

skip(size)#
property suffix: str#
tell()#

Return current stream position.

Return type:

int

transform(transforms=None)#

Apply format-specific transforms to model data.

transforms: EncoderTransforms = None#

Format-specific transforms applied to model data before serialization.

truncate()#

Truncate file to size bytes.

File pointer is left unchanged. Size defaults to the current IO position as reported by tell(). Returns the new size.

unicode_errors: str = 'replace'#

Error handling mode for UTF-8 encoding/decoding.

writable()#

Return whether object was opened for writing.

If False, write() will raise OSError.

Return type:

bool

write(data)#
Return type:

int

writelines(lines, /)#

Write a list of lines to stream.

Line separators are not added, so it is usual for each of the lines provided to have a line separator at the end.

data: ContentType#
options: Options#

Shared handlers options.
