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`.@@ -32,8 +40,11 @@ and do `stack install hascard` or `nix-build` respectively.  ## Usage-Simply run `hascard` to open the main application.

This, and a couple other things, can be changed in the settings menu. Currently there is no functionality for making cards inside the hascard application itself, but they can easily be written in your favorite text editor since the syntax is human-friendly.

As an example, say you have a file `deck.txt` with lots of cards in it and you want to review 5 random ones, you can use `hascard deck -s -a 5`. Here `-s` shuffles the deck and `-a 5` specifies we only want to look at 5 of them.+ ## Cards Decks of cards are written in `.txt` files. Cards are seperated with a line containing three dashes `---`. For examples, see the [`/cards`](https://github.com/Yvee1/hascard/tree/master/cards) directory. In this section the 4 different cards are listed, with the syntax and how it is represented in the application. @@ -84,4 +95,4 @@ ![](./recordings/gapped-question.gif)  ## 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).
