+# copyparty-fuse.py
+* mount a copyparty server as a local filesystem (read-only)
+* **supports Windows!** -- expect `194 MiB/s` sequential read
+* **supports Linux** -- expect `117 MiB/s` sequential read
+* **supports macos** -- expect `85 MiB/s` sequential read
+
+filecache is default-on for windows and macos;
+* macos readsize is 64kB, so speed ~32 MiB/s without the cache
+* windows readsize varies by software; explorer=1M, pv=32k
+
+note that copyparty should run with `-ed` to enable dotfiles (hidden otherwise)
+
+also consider using [../docs/rclone.md](../docs/rclone.md) instead for 5x performance
+
+
+## to run this on windows:
+* install [winfsp](https://github.com/billziss-gh/winfsp/releases/latest) and [python 3](https://www.python.org/downloads/)
+  * [x] add python 3.x to PATH (it asks during install)
+* `python -m pip install --user fusepy`
+* `python ./copyparty-fuse.py n: http://192.168.1.69:3923/`
+
+10% faster in [msys2](https://www.msys2.org/), 700% faster if debug prints are enabled:
+* `pacman -S mingw64/mingw-w64-x86_64-python{,-pip}`
+* `/mingw64/bin/python3 -m pip install --user fusepy`
+* `/mingw64/bin/python3 ./copyparty-fuse.py [...]`
+
+you could replace winfsp with [dokan](https://github.com/dokan-dev/dokany/releases/latest), let me know if you [figure out how](https://github.com/dokan-dev/dokany/wiki/FUSE)  
+(winfsp's sshfs leaks, doesn't look like winfsp itself does, should be fine)

+# 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
+
+
+### 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
+
+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    |
+
+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
