## About
|
|
Sometimes, you just need a way to randomly display media from your filesystem.
|
|
|
|
Simply point this tool at one or more directories, and then open the specified port (default `8080`) in your browser.
|
|
|
|
A new file will be selected if you open `/` directly, or if you click on any displayed files.
|
|
|
|
Browser history is preserved, so you can always go back to any previously displayed media.
|
|
|
|
Feature requests, code criticism, bug reports, general chit-chat, and unrelated angst accepted at `roulette@seedno.de`.
|
|
|
|
Static binary builds available [here](https://cdn.seedno.de/builds/roulette).
|
|
|
|
I only test the linux/amd64, linux/arm64, and windows/amd64 builds, the rest are all best-effort™.
|
|
|
|
x86_64 and ARM Docker images of latest version: `oci.seedno.de/seednode/roulette:latest`.
|
|
|
|
Dockerfile available [here](https://git.seedno.de/seednode/roulette/raw/branch/master/docker/Dockerfile).
|
|
|
|
## Filtering
|
|
You can provide a comma-delimited string of alphanumeric patterns to match via the `include=` query parameter, assuming the `-f|--filter` flag is enabled.
|
|
|
|
Only filenames matching one or more of the patterns will be served.
|
|
|
|
You can also provide a comma-delimited string of alphanumeric patterns to exclude, via the `exclude=` query parameter.
|
|
|
|
Filenames matching any of these patterns will not be served.
|
|
|
|
You can combine these two parameters, with exclusions taking priority over inclusions.
|
|
|
|
Both filtering parameters ignore the file extension and full path; they only compare against the bare filename.
|
|
|
|
## Indexing
|
|
If the `-i|--indexing` flag is passed, all specified paths will be indexed on start.
|
|
|
|
This will slightly increase the delay before the application begins responding to requests, but should significantly speed up subsequent requests.
|
|
|
|
The index can be regenerated at any time by accessing the `/rebuild_index` endpoint.
|
|
|
|
If `--index-file` is set, the index will be loaded from the specified file on start, and written to the file whenever it is re-generated.
|
|
|
|
## Info
|
|
If the `-i|--info` flag is passed, six additional endpoints are registered.
|
|
|
|
The first of these—`/html` and `/json`—return the contents of the index, in HTML and JSON formats respectively.
|
|
|
|
If `--page-length` is also set, these can be viewed in paginated form by appending `/n`, e.g. `/html/5` for the fifth page.
|
|
|
|
This can prove useful when confirming whether the index is generated successfully, or whether a given file is in the index.
|
|
|
|
The remaining four endpoints—`/available_extensions`, `/enabled_extensions`, `/available_mime_types` and `/enabled_mime_types`—return information about the registered file types.
|
|
|
|
## Refresh
|
|
If the `--refresh` flag is passed and a positive-value `refresh=<integer><unit>` query parameter is provided, the page will reload after that interval.
|
|
|
|
This can be used to generate a sort of slideshow of files in any browser with Javascript support.
|
|
|
|
Pressing Spacebar will pause automatic refreshing until Spacebar is pressed again, the page is manually refreshed, or a new page is loaded.
|
|
|
|
Minimum accepted value is 500ms, as anything lower seems to cause inconsistent behavior. This might be changed in a future release.
|
|
|
|
Supported units are `ns`, `us`/`µs`, `ms`, `s`, `m`, and `h`.
|
|
|
|
## Russian
|
|
If the `--russian` flag is passed, everything functions exactly as you would expect.
|
|
|
|
That is, files will be deleted after being served. This is not a joke, you *will* lose data.
|
|
|
|
This uses `os.Remove()` and checks to ensure the specified file is inside one of the paths passed to `roulette`.
|
|
|
|
That said, this has not been tested to any real extent, so only pass this flag on systems you don't care about.
|
|
|
|
Enjoy!
|
|
|
|
## Sorting
|
|
You can specify a sorting direction via the `sort=` query parameter, assuming the `-s|--sort` flag is enabled.
|
|
|
|
A value of `sort=asc` means files will be served in ascending order (lowest-numbered to highest).
|
|
|
|
If a file exists with a numbered suffix one higher than the currently displayed file, it will be served next.
|
|
|
|
A value of `sort=desc` means files will be served in descending order (highest-numbered to lowest).
|
|
|
|
If a file exists with a numbered suffix one lower than the currently displayed file, it will be served next.
|
|
|
|
In either case, if no sequential file is found, a new random one will be chosen.
|
|
|
|
For `sort=asc`, the lowest-numbered file matching a given name will be served first.
|
|
|
|
For `sort=desc`, the highest-numbered file will be served instead.
|
|
|
|
If any other (or no) value is provided, the selected file will be random.
|
|
|
|
Note: These options require sequentially-numbered files matching the following pattern: `filename[0-9]*.extension`.
|
|
|
|
## Themes
|
|
The `--code` handler provides syntax highlighting via [alecthomas/chroma](https://github.com/alecthomas/chroma).
|
|
|
|
Any [supported theme](https://pkg.go.dev/github.com/alecthomas/chroma/v2@v2.9.1/styles#pkg-variables) can be passed via the `--theme` flag.
|
|
|
|
By default, [`solarized-dark256`](https://xyproto.github.io/splash/docs/solarized-dark256.html) is used.
|
|
|
|
