+## quickstart
+
+download [copyparty-sfx.py](https://github.com/9001/copyparty/releases/latest/download/copyparty-sfx.py) and you're all set!
+
+running the sfx without arguments (for example doubleclicking it on Windows) will let anyone access the current folder; see `-h` for help if you want accounts and volumes etc
+
+you may also want these, especially on servers:
+* [contrib/systemd/copyparty.service](contrib/systemd/copyparty.service) to run copyparty as a systemd service
+* [contrib/nginx/copyparty.conf](contrib/nginx/copyparty.conf) to reverse-proxy behind nginx (for legit https)
+
+
 ## notes
 
 * iPhone/iPad: use Firefox to download files
 * Android-Chrome: set max "parallel uploads" for 200% upload speed (android bug)
 * Android-Firefox: takes a while to select files (in order to avoid the above android-chrome issue)
 * Desktop-Firefox: may use gigabytes of RAM if your connection is great and your files are massive
+* paper-printing is affected by dark/light-mode! use lightmode for color, darkmode for grayscale
+  * because no browsers currently implement the media-query to do this properly orz

 summary: it works! you can use it! (but technically not even close to beta)
 
 
+# bugs
+
+* probably, pls let me know
+
+
+# searching
+
+when started with `-e2dsa` copyparty will scan/index all your files. This avoids duplicates on upload, and also makes the volumes searchable through the web-ui:
+* make search queries by `size`/`date`/`directory-path`/`filename`, or...
+* drag/drop a local file to see if the same contents exist somewhere on the server (you get the URL if it does)
+
+path/name queries are space-separated, AND'ed together, and words are negated with a `-` prefix, so for example:
+* path: `shibayan -bossa` finds all files where one of the folders contain `shibayan` but filters out any results where `bossa` exists somewhere in the path
+* name: `demetori styx` gives you [good stuff](https://www.youtube.com/watch?v=zGh0g14ZJ8I&list=PL3A147BD151EE5218&index=9)
+
+add `-e2ts` to also scan/index tags from music files:
+
+
+## search configuration
+
+searching 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.
+
+through arguments:
+* `-e2d` enables file indexing on upload
+* `-e2ds` scans writable folders on startup
+* `-e2dsa` scans all mounted volumes (including readonly ones)
+* `-e2t` enables metadata indexing on upload
+* `-e2ts` scans for tags in all files that don't have tags yet
+* `-e2tsr` deletes all existing tags, so a full reindex
+
+the same arguments can be set as volume flags, in addition to `d2d` and `d2t` for disabling:
+* `-v ~/music::ce2dsa:ce2tsr` does a full reindex of everything on startup
+* `-v ~/music::cd2d` disables **all** indexing, even if any `-e2*` are on
+* `-v ~/music::cd2t` disables all `-e2t*` (tags), does not affect `-e2d*`
+
+`e2tsr` is probably always overkill, since `e2ds`/`e2dsa` would pick up any file modifications and cause `e2ts` to reindex those
+
+`-mte` decides which tags to index and display in the browser (and also the display order), this can be changed per-volume:
+* `-v ~/music::cmte=title,artist` indexes and displays *title* followed by *artist*
+
+if you add/remove a tag from `mte` you will need to run with `-e2tsr` once to rebuild the database, otherwise only new files will be affected
+
+`-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`
+
+see the beautiful mess of a dictionary in [mtag.py](https://github.com/9001/copyparty/blob/master/copyparty/mtag.py) for the default mappings (should cover mp3,opus,flac,m4a,wav,aif,)
+
+`--no-mutagen` disables mutagen and uses ffprobe instead, which...
+* is about 20x slower than mutagen
+* catches a few tags that mutagen doesn't
+* avoids pulling any GPL code into copyparty
+* more importantly runs ffprobe on incoming files which is bad if your ffmpeg has a cve
+
+
+# client examples
+
+* javascript: dump some state into a file (two separate examples)
+  * `await fetch('https://127.0.0.1:3923/', {method:"PUT", body: JSON.stringify(foo)});`
+  * `var xhr = new XMLHttpRequest(); xhr.open('POST', 'https://127.0.0.1:3923/msgs?raw'); xhr.send('foo');`
+
+* curl/wget: upload some files (post=file, chunk=stdin)
+  * `post(){ curl -b cppwd=wark http://127.0.0.1:3923/ -F act=bput -F f=@"$1";}`  
+    `post movie.mkv`
+  * `post(){ wget --header='Cookie: cppwd=wark' http://127.0.0.1:3923/?raw --post-file="$1" -O-;}`  
+    `post movie.mkv`
+  * `chunk(){ curl -b cppwd=wark http://127.0.0.1:3923/ -T-;}`  
+    `chunk <movie.mkv`
+
+* FUSE: mount a copyparty server as a local filesystem
+  * cross-platform python client available in [./bin/](bin/)
+  * [rclone](https://rclone.org/) as client can give ~5x performance, see [./docs/rclone.md](docs/rclone.md)
+
+copyparty returns a truncated sha512sum of your PUT/POST as base64; you can generate the same checksum locally to verify uplaods:
+
+    b512(){ printf "$((sha512sum||shasum -a512)|sed -E 's/ .*//;s/(..)/\\x\1/g')"|base64|head -c43;}
+    b512 <movie.mkv

 currently there are two self-contained binaries:
-* `copyparty-sfx.sh` for unix (linux and osx) -- smaller, more robust
-* `copyparty-sfx.py` for windows (unix too) -- crossplatform, beta
+* [copyparty-sfx.py](https://github.com/9001/copyparty/releases/latest/download/copyparty-sfx.py) -- pure python, works everywhere
+* [copyparty-sfx.sh](https://github.com/9001/copyparty/releases/latest/download/copyparty-sfx.sh) -- smaller, but only for linux and macos
 
-launch either of them and it'll unpack and run copyparty, assuming you have python installed of course
+launch either of them (**use sfx.py on systemd**) and it'll unpack and run copyparty, assuming you have python installed of course
 
 pls note that `copyparty-sfx.sh` will fail if you rename `copyparty-sfx.py` to `copyparty.py` and keep it in the same folder because `sys.path` is funky
 
-if you don't need all the features you can repack the sfx and save a bunch of space, tho currently the only removable feature is the opus/vorbis javascript decoder which is needed by apple devices to play foss audio files
 
-steps to reduce the sfx size from `720 kB` to `250 kB` roughly:
-* run one of the sfx'es once to unpack it
-* `./scripts/make-sfx.sh re no-ogv` creates a new pair of sfx
+## sfx repack
 
-no internet connection needed, just download an sfx and the repo zip (also if you're on windows use msys2)
+if you don't need all the features you can repack the sfx and save a bunch of space; all you need is an sfx and a copy of this repo (nothing else to download or build, except for either msys2 or WSL if you're on windows)
+* `724K` original size as of v0.4.0
+* `256K` after `./scripts/make-sfx.sh re no-ogv`
+* `164K` after `./scripts/make-sfx.sh re no-ogv no-cm`
+
+the features you can opt to drop are
+* `ogv`.js, the opus/vorbis decoder which is needed by apple devices to play foss audio files
+* `cm`/easymde, the "fancy" markdown editor
+
+for the `re`pack to work, first run one of the sfx'es once to unpack it
+
+**note:** you can also just download and run [scripts/copyparty-repack.sh](scripts/copyparty-repack.sh) -- this will grab the latest copyparty release from github and do a `no-ogv no-cm` repack; works on linux/macos (and windows with msys2 or WSL)

+* works on windows, linux and macos
+* assumes `copyparty-sfx.py` was renamed to `copyparty.py` in the same folder as `copyparty.bat`
+
+### [`index.html`](index.html)
+* drop-in redirect from an httpd to copyparty
+* assumes the webserver and copyparty is running on the same server/IP

+
+### [`explorer-nothumbs-nofoldertypes.reg`](explorer-nothumbs-nofoldertypes.reg)
+* disables thumbnails and folder-type detection in windows explorer
+* makes it way faster (especially for slow/networked locations (such as copyparty-fuse))
+
+### [`cfssl.sh`](cfssl.sh)
+* creates CA and server certificates using cfssl

+# hi
+this showcases my worst idea yet; *extending markdown with inline javascript*
+
+due to obvious reasons it's disabled by default, and can be enabled with `-emp`
+
+the examples are by no means correct, they're as much of a joke as this feature itself
+
+
+### sub-header
+nothing special about this one
+
+
+## except/
+this one becomes a hyperlink to ./except/ thanks to
+* the `copyparty_pre` plugin at the end of this file
+* which is invoked as a markdown filter every time the document is modified
+* which looks for headers ending with a `/` and erwrites all headers below that
+
+it is a passthrough to the markdown extension api, see https://marked.js.org/using_pro
+
+in addition to the markdown extension functions, `ctor` will be called on document init
+
+
+### these/
+and this one becomes ./except/these/
+
+
+#### ones.md
+finally ./except/these/ones.md
+
+
+### also-this.md
+whic hshoud be ./except/also-this.md
+
+
+
+
+# ok
+now for another extension type, `copyparty_post` which is called to manipulate the generated dom instead
+
+`copyparty_post` can have the following functions, all optional
+* `ctor` is called on document init
+* `render` is called when the dom is done but still in-memory
+* `render2` is called with the live browser dom as-displayed
+
+## post example
+
+the values in the `ex:` columns are linkified to `example.com/$value`
+
+| ex:foo       | bar      | ex:baz |
+| ------------ | -------- | ------ |
+| asdf         | nice     | fgsfds |
+| more one row | hi hello | aaa    |
+
+and the table can be sorted by clicking the headers
+
+the difference is that with `copyparty_pre` you'll probably break various copyparty features but if you use `copyparty_post` then future copyparty versions will probably break you
+
