A simple CLI tool to calculate your BMI, written in Crystal Lang.
- Install using
shards install crystal build src/bmi-cli.crmv bmi-cli bin/ && mv bmi-cli.dwarf bin/
Alternatively you can use Cake (Crystal make) by just running cake
Run bin/bmi-cli --help to see help screen with all info on it.
This is run simply be accessing the class: BmiValues::Calculate.new(height, weight, units)
You can also use the tool by running a command from the binary you created (and moved). This will work like any old binary.
./bmi-cli - This will pass in all the defaults through so you can see how it works
You can pass in your own flags to input your own data
./bmi-cli imperial --height=6.5 --weight=190 --name=Jimbob
You can pass in your own flags to input your own data
./bmi-cli metric --height=1.3 --weight=80 --name=Jimbob
This should output something like...
Calculating BMI...
Your BMI is: 20.798816568047336
You're considered: Normal
There's also defaults set so that if a field is missing it'll have something to pass through Right now the defaults are;
units->"Imperial"height->5.11weight->180
To see all defaults run bin/bmi-cli --help.
You can change the output to fit whatever project, like a csv file for example: ./bmi-cli --height=6.5 --weight=190 >> log.csv
