### Binary
Ubuntu and macOS binaries are available under [releases](https://github.com/Yvee1/hascard/releases/). To be able to run it from any directory, it has to be added to the PATH. This can be done by copying it to e.g. the `/usr/local/bin` directory.
+### Arch Linux
+Thanks to [loki7990](https://github.com/loki7990), hascard is also on the AUR: https://aur.archlinux.org/packages/hascard/.
+
### Snapcraft
Hascard is also on [snapcraft](https://snapcraft.io/hascard). Installation instructions are on that site. If you already have snap installed you can just install hascard via `sudo snap install hascard`. By default snap applications are isolated from the system and run in a sandbox. This means that hascard does not have permission to read or write any files on the system aside from those under `%HOME/snap/hascard`. To be able to read cards also in other directories under the home directory, hascard makes use of the `home` interface which might need to be enabled manually using `sudo snap connect hascard:home :home`.

### Open question
Open questions are also supported. The words that have to be filled in should be surrounded by underscores `_`. Underscores can also be escaped by `\_` if they are part of the text, like is done in [`cards/analysis3.txt`](https://github.com/Yvee1/hascard/blob/48b5c0751ac72df791402b88c033e05488c9350d/cards/analysis3.txt#L34-L37t).

## Miscellaneous info
Written in Haskell, UI built with [brick](https://github.com/jtdaugherty/brick) and parsing of cards done with [parsec](https://github.com/haskell/parsec). Recordings of the terminal were made using [terminalizer](https://github.com/faressoft/terminalizer). The filebrowser widget was mostly copied from the brick [filebrowser demo program](https://github.com/jtdaugherty/brick/blob/master/programs/FileBrowserDemo.hs). Homebrew and Travis configurations were made much easier by [the tutorial from Chris Penner](https://chrispenner.ca/posts/homebrew-haskell).
