1 | # A Krabby-gotchi (via the terminal)
2 |
3 | 
4 | her real name is sally^
5 |
6 |
7 | ## What is this?
8 | Imagine a future where everyone had a crustacious companion.
9 |
10 | **A world devoid of conflict.**
11 |
12 | I present humbly to thee,
13 |
14 | ### A Krabby-gotchi 🦀
15 | (tamagotchi but crab)
16 |
17 | ## Ok but what really is this?
18 | The krabs made me do it.
19 |
20 | ## Ok but what *really really* is this?
21 | Learning rust.
22 |
23 | Hopefully will have a terminal tamagotchi by the end because tamagotchis
24 | are expensive and crabs are free if you are near an ocean.
25 |
26 | ## Install
27 | Its on crate.io!
28 |
29 |
30 | ```
31 | cargo install mrKrabs@1.1.0
32 | ```
33 |
34 |
35 | ## Dev
36 | Get Rust
37 | ```
38 | curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
39 | ```
40 | Clone this repo, cd into it and run
41 | ```
42 | cargo run
43 | ```
44 | ## TODO
45 | - [x] saving and config
46 | - [x] have krab stats
47 | - [x] feed the krab
48 | - [x] pet the krab
49 | - [x] tick down/ up status overtime
50 | - [x] forge the krab (animate)
51 | - [ ] animate the krab moving around perhaps
52 | - [ ] think about *maybe* implementing lobsters
53 | - [ ] make mood, status and stage enums later
54 |
55 | ## Contributing
56 | - If you spot a bug (which there probabably are many), put in an issue with how to reproduce it.
57 | - If you want to suggest a feature put in an issue with the feature request.
58 | - If you want to contribute code, make a pull request. anything short of a war crime will probably be accepted.
