PTREPACK(1)

💖 PTREPACK(1) 💖

okay so bestie, welcome to the General Commands Manual glow-up of ptrepack 👑 this is the whole entire vibe, no cap.

✨ NAME ✨

ptrepack — copy any PyTables Leaf, Group or complete subtree into another file 🦋

✨ SYNOPSIS ✨

ptrepack -h -v -o -R start,stop,step --non-recursive --dest-title=title
--dont-copyuser-attrs --overwrite-nodes --complevel=(0-9) --complib=lib
--shuffle=(0|1) --fletcher32=(0|1) --keep-source-filters
--upgrade-flavors --dont-regenerate-old-indexes sourcefile:sourcegroup
destfile:destgroup

✨ DESCRIPTION ✨

So basically 💅 ptrepack copies any Leaf, Group or complete subtree out of a PyTables file and drops it into a whole other file. It's giving moving day, but for your data. Slay.

✨ OPTIONS ✨

Here's the lil rundown of everything you can pass it, bestie — every single one, we're not skipping a thing 🫶

• -h — prints a help text. ur friendly lil "what do I even type" button 🌸
• -v — show more information. she's chatty and we love that for her ✨
• -o — overwrite the destination file. bold move, iconic energy 💅
• -R RANGE — pick a RANGE of rows, in the form start,stop,step, while copying all the leaves. like a lil slice of the whole cake 🍓
• --non-recursive — do NOT do a recursive copy. (default is that it does do the recursive copy, so this is the "actually, just the one level please" flag 🙈)
• --dest-title=title — title for the new file. if u don't specify one, the source gets copied over instead 🎀
• --dont-copy-userattrs — do not copy the user attrs (default is to copy them, so this is the "leave my lil extras at home" option) 💜
• --overwrite-nodes — overwrite destination nodes if they already exist. default is not to overwrite them, so heads up ⚠️
• --complevel=(0-9) — set a compression level. 0 means no compression, and that's the default 🧚
• --complib=lib — set the compression library to be used during the copy. lib can be "zlib", "lzo", "ucl" or "bzip2". defaults to "zlib" 💖
• --shuffle=(0|1) — activate or not the shuffling filter. default is active if complevel>0 🔥
• --fletcher32=(0|1) — whether to activate or not the fletcher32 filter. not active by default 🌈
• --keep-source-filters — use the original filters from the source files. the default is not doing that if any of --complevel, --complib, --shuffle or --fletcher32 is specified ⭐
• --upgrade-flavors — when repacking PyTables 1.x files, the flavor of leaves gets unset. with this, such leaves get serialized as objects with the internal flavor ("numpy" for the 2.x series) 👑
• --dont-regenerate-old-indexes — disable regenerating old indexes. the default is to regenerate old indexes as they're found 🔍
