# <img src="docs/_static/fileseq_large.png" width="30%" height="30%" title="Fileseq" alt="Fileseq"> [![Documentation Status](https://readthedocs.org/projects/fileseq/badge/?version=latest)](http://fileseq.readthedocs.io/en/latest/) [![Build status](https://github.com/justinfx/fileseq/actions/workflows/ci.yml/badge.svg)](https://github.com/justinfx/fileseq/actions/workflows/ci.yml) A Python library for parsing frame ranges and file sequences commonly used in VFX and Animation applications. ## Frame Range Shorthand Support for: * Standard: 1-10 * Comma Delimited: 1-10,10-20 * Chunked: 1-100x5 * Filled: 1-100y5 * Staggered: 1-100:3 (1-100x3, 1-100x2, 1-100) * Negative frame numbers: -10-100 * Subframes: 1001-1066x0.25, 1001.5-1066.0x0.5 * Padding: #=4 padded, @=1 padded * Alternate padding: #=1 padded, @=1 padded * Printf Syntax Padding: %04d=4 padded, %01d=1 padded * Houdini Syntax Padding: $F4=4 padding, $F=1 padded * Udim Syntax Padding: <UDIM> or %(UDIM)d, always 4 padded ## FrameSets A FrameSet wraps a sequence of frames in a list container. ### Iterate a FrameSet ```python fs = fileseq.FrameSet("1-5") for f in fs: print f ``` ### Access Frames #### Using Indices: ```python >>> fs = fileseq.FrameSet("1-100:8") >>> fs[0] # First frame. 1 >>> fs[-1] # Last frame. 98 ``` #### Using Convenience Methods: ```python >>> fs = fileseq.FrameSet("1-100:8") >>> fs.start() # First frame. 1 >>> fs.end() # Last frame. 98 ``` ## FileSequence ### Instantiate from String ```python fileseq.FileSequence("/foo/bar.1-10#.exr") fileseq.FileSequence("/foo/bar.1-10x0.25#.#.exr", allow_subframes=True) ``` ### Format Path for VFX Software #### Using FileSequence.format Method: ```python >>> seq = fileseq.FileSequence("/foo/bar.1-10#.exr") >>> seq.format(template='{dirname}{basename}{padding}{extension}') "/foo/bar.#.exr" >>> seq = fileseq.FileSequence("/foo/bar.1-10#.#.exr", allow_subframes=True) >>> seq.format(template='{dirname}{basename}{padding}{extension}') "/foo/bar.#.#.exr" ``` #### Joining: ```python >>> seq = fileseq.FileSequence("/foo/bar.1-10#.exr") >>> ''.join([seq.dirname(), seq.basename(), '%0{}d'.format(len(str(seq.end()))), seq.extension()]) "/foo/bar.%02d.exr" ``` #### Alternate Padding Styles: ```python >>> seq = fileseq.FileSequence("/foo/bar.1-10#.exr", pad_style=fileseq.PAD_STYLE_HASH1) >>> list(seq) ['/foo/bar.1.exr', '/foo/bar.2.exr', '/foo/bar.3.exr', '/foo/bar.4.exr', '/foo/bar.5.exr', '/foo/bar.6.exr', '/foo/bar.7.exr', '/foo/bar.8.exr', '/foo/bar.9.exr', '/foo/bar.10.exr'] >>> seq = fileseq.FileSequence("/foo/bar.1-10#.exr", pad_style=fileseq.PAD_STYLE_HASH4) >>> list(seq) ['/foo/bar.0001.exr', '/foo/bar.0002.exr', '/foo/bar.0003.exr', '/foo/bar.0004.exr', '/foo/bar.0005.exr', '/foo/bar.0006.exr', '/foo/bar.0007.exr', '/foo/bar.0008.exr', '/foo/bar.0009.exr', '/foo/bar.0010.exr'] ``` ### Get List of File Paths ```python >>> seq = fileseq.FileSequence("/foo/bar.1-10#.exr") >>> [seq[idx] for idx, fr in enumerate(seq.frameSet())] ['/foo/bar.0001.exr', '/foo/bar.0002.exr', '/foo/bar.0003.exr', '/foo/bar.0004.exr', '/foo/bar.0005.exr', '/foo/bar.0006.exr', '/foo/bar.0007.exr', '/foo/bar.0008.exr', '/foo/bar.0009.exr', '/foo/bar.0010.exr'] ``` ## Finding Sequences on Disk ### Check a Directory for All Existing Sequences ```python seqs = fileseq.findSequencesOnDisk("/show/shot/renders/bty_foo/v1") ``` ### Check a Directory for One Existing Sequence. * Use a '@' or '#' where you might expect to use '*' for a wildcard character. * For this method, it doesn't matter how many instances of the padding character you use, it will still find your sequence. Yes: ```python fileseq.findSequenceOnDisk('/foo/bar.@.exr') ``` Yes: ```python fileseq.findSequenceOnDisk('/foo/bar.@@@@@.exr') ``` No: ```python fileseq.findSequenceOnDisk('/foo/bar.*.exr') ``` * To find subframe sequences you must explicitly opt-in ```python fileseq.findSequenceOnDisk('/foo/bar.#.#.exr', allow_subframes=True) ``` ## Limitations While there may be many custom types of sequence patterns that could be considered a valid pipeline format, this library has taken an opinionated stance on acceptable sequence formats. This is done to keep parsing rules manageable and to not over-complicate the logic. The parsing rules can and have been expanded in some ways over time, such as adding support for new padding format patterns like printf "%04d", houdini "$F" and "<UDIM>". But other rules remain the same, such as expecting a frame number component to be found just before the file extension component. ## Language Ports * Go: https://github.com/justinfx/gofileseq * C++: https://github.com/justinfx/gofileseq/tree/master/cpp
