-  * uploads resume if they are interrupted (for example by a reboot)
+  * uploads autoresume if they are interrupted by network issues

 * the last-modified timestamp of the file is preserved

+* `[✅ apply rename]` confirms and begins renaming
+* `[❌ cancel]` aborts and closes the rename window
+* `[↺ reset]` reverts any filename changes back to the original name
+* `[decode]` does a URL-decode on the filename, fixing stuff like `&` and `%20`
+* `[advanced]` toggles advanced mode
+
+advanced mode: rename files based on rules to decide the new names, based on the original name (regex), or based on the tags collected from the file (artist/title/...), or a mix of both
+
+in advanced mode,  
+* `[case]` toggles case-sensitive regex
+* `regex` is the regex pattern to apply to the original filename; any files which don't match will be skipped
+* `format` is the new filename, taking values from regex capturing groups and/or from file tags
+  * very loosely based on foobar2000 syntax
+* `presets` lets you save rename rules for later

+available functions:
+* `$lpad(text, length, pad_char)`

+so,
+
+say you have a file named [`meganeko - Eclipse - 07 Sirius A.mp3`](https://www.youtube.com/watch?v=-dtb0vDPruI) (absolutely fantastic album btw) and the tags are: `Album:Eclipse`, `Artist:meganeko`, `Title:Sirius A`, `tn:7`
+
+you could use just regex to rename it:
+* `regex` = `(.*) - (.*) - ([0-9]{2}) (.*)`
+* `format` = `(3). (1) - (4)`
+* `output` = `07. meganeko - Sirius A.mp3`
+
+or you could use just tags:
+* `format` = `$lpad((tn),2,0). (artist) - (title).(ext)`
+* `output` = `7. meganeko - Sirius A.mp3`
+
+or a mix of both:
+* `regex` = ` - ([0-9]{2}) `
+* `format` = `(1). (artist) - (title).(ext)`
+* `output` = `07. meganeko - Sirius A.mp3`
+
+the metadata keys you can use in the format field are the ones in the file-browser table header (whatever is collected with `-mte` and `-mtp`)

+file indexing relies on two databases, the up2k filetree (`-e2d`) and the metadata tags (`-e2t`). Configuration can be done through arguments, volume flags, or a mix of both.

 * `-e2d` enables file indexing on upload
-* `-e2ds` scans writable folders on startup
+* `-e2ds` scans writable folders for new files on startup
 * `-e2dsa` scans all mounted volumes (including readonly ones)

-* `-e2tsr` deletes all existing tags, so a full reindex
+* `-e2tsr` deletes all existing tags, does a full reindex
 
 the same arguments can be set as volume flags, in addition to `d2d` and `d2t` for disabling:
-* `-v ~/music::r:ce2dsa:ce2tsr` does a full reindex of everything on startup
+* `-v ~/music::r:c,e2dsa:c,e2tsr` does a full reindex of everything on startup
-* `-v ~/music::r:cd2d` disables **all** indexing, even if any `-e2*` are on
+* `-v ~/music::r:c,d2d` disables **all** indexing, even if any `-e2*` are on

+* `-v ~/music::r:c,d2t` disables all `-e2t*` (tags), does not affect `-e2d*`

+* `e2tsr` is probably always overkill, since `e2ds`/`e2dsa` would pick up any file modifications and `e2ts` would then reindex those, unless there is a new copyparty version with new parsers and the release note says otherwise

+## upload rules
+
+set upload rules using volume flags, some examples:
+
+* `:c,sz=1k-3m` sets allowed filesize between 1 KiB and 3 MiB inclusive (suffixes: b, k, m, g)
+* `:c,nosub` disallow uploading into subdirectories; goes well with `rotn` and `rotf`:
+* `:c,rotn=1000,2` moves uploads into subfolders, up to 1000 files in each folder before making a new one, two levels deep (must be at least 1)
+* `:c,rotf=%Y/%m/%d/%H` enforces files to be uploaded into a structure of subfolders according to that date format
+  * if someone uploads to `/foo/bar` the path would be rewritten to `/foo/bar/2021/08/06/23` for example
+  * but the actual value is not verified, just the structure, so the uploader can choose any values which conform to the format string
+    * just to avoid additional complexity in up2k which is enough of a mess already
+* `:c,lifetime=300` delete uploaded files when they become 5 minutes old
+
+you can also set transaction limits which apply per-IP and per-volume, but these assume `-j 1` (default) otherwise the limits will be off, for example `-j 4` would allow anywhere between 1x and 4x the limits you set depending on which processing node the client gets routed to
+
+* `:c,maxn=250,3600` allows 250 files over 1 hour from each IP (tracked per-volume)
+* `:c,maxb=1g,300` allows 1 GiB total over 5 minutes from each IP (tracked per-volume)
+
+
+## compress uploads
+
+files can be autocompressed on upload
+
+compression is either on user-request (if config allows) or forced by server-config
+
+* volume flag `gz` allows gz compression
+* volume flag `xz` allows lzma compression
+* volume flag `pk` **forces** compression on all files
+* url parameter `pk` requests compression with server-default algorithm
+* url parameter `gz` or `xz` requests compression with a specific algorithm
+* url parameter `xz` requests xz compression
+
+things to note,
+* the `gz` and `xz` arguments take a single optional argument, the compression level (range 0 to 9)
+* the `pk` volume flag takes the optional argument `ALGORITHM,LEVEL` which will then be forced for all uploads, for example `gz,9` or `xz,0`
+* default compression is gzip level 9
+* all upload methods except up2k are supported
+* the files will be indexed after compression, so dupe-detection and file-search will not work as expected

 copyparty creates a subfolder named `.hist` inside each volume where it stores the database, thumbnails, and some other stuff
 
 this can instead be kept in a single place using the `--hist` argument, or the `hist=` volume flag, or a mix of both:
-* `--hist ~/.cache/copyparty -v ~/music::r:chist=-` sets `~/.cache/copyparty` as the default place to put volume info, but `~/music` gets the regular `.hist` subfolder (`-` restores default behavior)
+* `--hist ~/.cache/copyparty -v ~/music::r:c,hist=-` sets `~/.cache/copyparty` as the default place to put volume info, but `~/music` gets the regular `.hist` subfolder (`-` restores default behavior)

 ## metadata from audio files

+* `-v ~/music::r:c,mte=title,artist` indexes and displays *title* followed by *artist*

 `-mtm` can be used to add or redefine a metadata mapping, say you have media files with `foo` and `bar` tags and you want them to display as `qux` in the browser (preferring `foo` if both are present), then do `-mtm qux=foo,bar` and now you can `-mte artist,title,qux`

+
+more notes
+- adding -hls_flags single_file makes duration wack during playback (for both fmp4 and ts), ok once finalized and refreshed, gives no size reduction anyways
+- bebop op has good keyframe spacing for testing hls.js, in particular it hops one seg back and immediately resumes if it hits eof with the explicit hls.startLoad(0); otherwise it jumps into the middle of a seg and becomes art
+- can probably -c:v copy most of the time, is there a way to check for cgop? todo
