Dependencies

• make

Usage

create a kata

1. create a folder named katas
2. add the name for a kata you want to create

mkdir -p katas/hello_world

3. add the skeleton, this is the entrypoint for each day

// hello.go
func helloWorld() {
}

func main() {
    helloWorld()
}

begin a new day

to begin a new day run the katac command with the kata or katas you want to do: (it can also be a path)

# katac <kata_name>...
katac hello_world

this will create a days folder which will contain a day1 containing your kata

run your kata

you can run your kata if the kata has a Makefile (if you have make), or a run.sh (run.bat for windows)

# Makefile
run:
	go run hello.go

after you are done writing the kata like in this example:

import "fmt"
func helloWorld() {
    fmt.Println("hello world")
}

func main() {
    helloWorld()
}

you can run it by doing this:

# katac run [kata_name]...
katac run

change katas folder and days folder permanently

you can create a katac.toml file that looks like this:

[katas]
katas_dir = "go-katas"
days_dir = "go-days"

run random katas

you can run random katas by using the random command and giving the number of random katas you want to do, like this

# this will copy 4 randomly selected katas from your katas directory to your days directory
katac random 4

randomly select a subset of katas

if you want to choose the katas the random command will work on, you can add this property to the katac.toml file

[katas]
random = ["Map", "LRU", "Trie", "Stack"]

initialize from examples

interactively select and copy example katas:

katac init

upgrade

update to the latest version:

katac upgrade
