# rpg-cli — your filesystem as a dungeon!



rpg-cli is a minimalist [computer RPG](https://en.wikipedia.org/wiki/Role-playing_video_game) written in Rust. Its command-line interface can be used as a `cd` replacement where you randomly encounter enemies as you change directories.

## Installation



### From binary



Just download the binary for your platform (linux/macOS/windows) from the [GitHub releases page](https://github.com/facundoolano/rpg-cli/releases/latest).



### Using Cargo

Assuming you have [Rust and Cargo installed](https://doc.rust-lang.org/cargo/getting-started/installation.html#install-rust-and-cargo):



    $ cargo install --git https://github.com/facundoolano/rpg-cli --force --tag 1.0.1



The binary should be available as `rpg-cli` (assuming you have `~/.cargo/bin` in your `$PATH`).



### Other installation methods



  Show details



#### Homebrew (macOS)

You can use homebrew to install the binary on macOS::



    $ brew install rpg-cli



#### Nixpkgs

If you use Nix/NixOS you can get rpg-cli from nixpkgs, either install it by adding it to your system config, with `nix-env -i rpg-cli`/`nix profile install nixpkgs#rpg-cli` or try it in a ephemeral shell with `nix-shell -p rpg-cli`/`nix shell nixpkgs#rpg-cli`.



#### Portage (Gentoo)

If you use Gentoo, you can get rpg-cli from portage:



    # emerge -av games-rpg/rpg-cli



#### Pacman (Arch Linux)



rpg-cli can be installed from the [extra repository](https://archlinux.org/packages/extra/x86_64/rpg-cli/) for Arch Linux:



    $ pacman -S rpg-cli



## Shell integration



The game is designed to integrate with common file system operations, such as changing directories or deleting files.

The most basic type of integration consists in wrapping rpg-cli in a shell function, such that the working directory is updated to match the hero's progress, effectively working as a `cd` alternative:



```sh

rpg () {

    rpg-cli "$@"

    cd "$(rpg-cli pwd)"

}

```



If you want to go all the way and *really* use it in place of `cd`:



```sh

cd () {

    rpg-cli cd "$@"

    builtin cd "$(rpg-cli pwd)"

}

```



Other commands like `rm`, `mkdir`, `touch`, etc. can also be aliased. Check [this example](shell/example.sh) and the [shell integration guide](shell/README.md) for more sophisticated examples, as well as their fish shell equivalents.



## Gameplay



This example session assumes a basic `rpg` function as described in the previous section.



### Character setup

The first time you run the program, a new hero is created at the user's home directory.



    ~ $ rpg

     warrior[1]@home

        hp:[xxxxxxxxxx] 48/48

        mp:[----------] 0/0

        xp:[----------] 0/30

        att:10   mag:0   def:0   spd:10

        equip:{}

        item:{}

        0g



When running without parameters, as above, the hero status is printed (health points, accumulated experience, etc.).

The stats are randomized: if you run `rpg reset` you will get a slightly different character every time:



    ~ $ rpg reset; rpg

     warrior[1]@home

        hp:[xxxxxxxxxx] 50/50

        mp:[----------] 0/0

        xp:[----------] 0/30

        att:13   mag:0   def:0   spd:12

        equip:{}

        item:{}

        0g



You can also pick a different class (default options are `warrior`, `thief` and `mage`, but [more can be added](#customize-character-classes)).

For example, the `mage` class enables magic attacks:



    ~ $ rpg class mage; rpg

        mage[1]@home

        hp:[xxxxxxxxxx] 32/32

        mp:[xxxxxxxxxx] 12/12

        xp:[----------] 0/30

        att:3   mag:27   def:0   spd:9

        equip:{}

        item:{}

        0g



### Movement and battles

If you use the `cd` subcommand with a path as parameter, it will instruct the hero to move:



    ~ $ rpg cd dev/

    ~/dev $ rpg

        warrior[1]@~/dev

        hp:[xxxxxxxxxx] 47/47

        mp:[----------] 0/0

        xp:[----------] 0/30

        att:10   mag:0   def:0   spd:12

        equip:{}

        item:{}

        0g



In this case, the warrior moved to `~/dev`. Sometimes enemies will appear as you move through the directories,

and both characters will engage in battle:



    ~/dev $ rpg cd facundoolano/

       snake[3][xxxx][----]@~/dev/facundoolano

       snake[3][xxx-] -10hp

     warrior[1][xxxx] -8hp

       snake[3][xxx-] -9hp

     warrior[1][xxx-] -10hp

       snake[3][x---] -12hp

     warrior[1][xx--] -9hp

       snake[3][----] -14hp

     warrior[3][xxx-] +117xp ++level +275g

     warrior[3][xxx-][----][x---]@~/dev/facundoolano



Each character attacks in turn (the frequency being determined by their `spd` stat).

Whenever you win a fight, your hero gains experience points and eventually raises its level, along with its other stats.



When you return to the home directory, the hero's health points are restored and status effects are removed:



    ~/dev/facundoolano/rpg-cli $ rpg cd ~

        warrior[3][xxxx][----][x---]@home +27hp



The further from home you move the hero, the tougher the enemies will get. If you go to far or too long without restoring your health, your hero is likely to die in battle, causing the game to restart at the home directory.



    ~ $ rpg cd ~/dev/facundoolano/rpg-cli/target/debug/examples/

      zombie[3][xxxx][----]@~/dev/facundoolano/rpg-cli/target/debug

      zombie[3][xxxx] -14hp

     warrior[1][xxx-] -14hp

      zombie[3][xxx-] -16hp

     warrior[1][xxx-] -11hp

      zombie[3][xx--] -16hp

     warrior[1][xx--] -9hp

      zombie[3][xx--] -15hp

     warrior[1][x---] -9hp

      zombie[3][x---] -12hp

     warrior[1][----] -20hp critical!

     warrior[1][----] 💀



Death is permanent: you can't save your progress and reload after dying, but if you take your new hero to the location of the previous one's death,

you can recover gold, items and equipment:



    ~ $ rpg cd ~/dev/facundoolano/rpg-cli/target/debug/

    ðŸŠĶ +potionx1 +275g



### Items and equipment



In addition to winning items as battle rewards, some directories have hidden treasure chests that you can find with `rpg ls`:



    ~ $ rpg ls

    ðŸ“Ķ  +potionx2



Finally, some items can be bought at the game directory running `rpg buy`:



    ~ $ rpg buy

        sword[1]    500g

        shield[1]   500g

        potion[1]   200g

        remedy      400g

        escape      1000g



        funds: 275g

    ~ $ rpg buy potion

       -200g +potionx1



The shortcut `rpg b p` would also work above. An item can be described with the `stat` subcommand and used with `use`:



    ~ $ rpg stat potion

    potion[1]: restores 25hp

    ~ $ rpg use potion

     warrior[3][xxxx] +25hp potion



### Quests and late game



The `rpg todo` command will display a list of quest for your hero:



    ~ $ rpg todo

      □ buy a sword

      ✔ use a potion

      ✔ reach level 2

      ✔ win a battle



Each time you complete an item on the list, you will receive a reward. The quests renew as your level raises, so be sure to check often!



The game difficulty increases as you go deeper in the dungeon; to raise your level, encounter the tougher enemies, find the rarest items

and complete all the quests, it's necessary to go as far as possible from the `$HOME` directory. One option to ease the gameplay

is to [use a shell function](https://github.com/facundoolano/rpg-cli/blob/main/shell/README.md#arbitrary-dungeon-levels) that creates directories "on-demand".



Try `rpg --help` for more options and check the [shell integration guide](shell/README.md) for ideas to adapt the game to your preferences.



## Customize character classes



The character class determines a character's initial stats and at what pace they increase when leveling up. By default, rpg-cli will use classes as defined by [this file](src/character/classes.yaml), but these definitions can be overridden by placing a YAML file with that same structure at `~/.local/share/rpg/classes.yaml`. Check the [dirs crate doc](https://docs.rs/dirs/3.0.2/dirs/fn.data_dir.html) to find the data path on your OS.



The `category` field is used to distinguish between player and enemy classes, and in the latter case how likely a given enemy class is likely to appear (e.g. `legendary` classes will appear less frequently, and only when far away from home).



The hero's class can be changed at the home directory using `rpg-cli class `. If the hero is at level 1 it will effectively work as a character re-roll with fresh stats; at higher levels the stats are preserved and the class change will start taking effect on the next level increment.



## Troubleshooting



* The release binary for macOS [is not signed](https://github.com/facundoolano/rpg-cli/issues/27). To open it for the first time, right click on the binary and select "Open" from the menu.
