Script inspired by others seen online, but namely by EjuiceCalculator and vaper.ninja's online calculator. And as me and python do not work well together, I decided to make my own bash script, seeing also that nobody had yet made a proper calculator with support for weight for linux.

Simply clone or download the script to the directory of your choice and make it executable.
The script is now also available in the AUR!
To install, simply yay -S vapecalc-cli (or paru -S if you use paru).

There are certain values that can be changed, such as default VG and PG weight values, display colors, temporary directory and saved recipes directory.
Some defaults are already added for conveninence.
All that's needed is to uncomment the ones you want to use.
All of the values are taken from vaper.ninja's website.

• Added weight value defaults (uncomment the ones you'd like to use):

## Default
vg="1.249"
pg="1.0361"

## Amazon Essentials
#vg="1.2881"
#pg="1.07887"

## botboy41 (https://www.reddit.com/r/DIY_eJuice/comments/2iq3km/botboy141_guide_to_mixing_by_weight/)
#vg="1.26"
#pg="1.038"

## v-ecigs.com (https://www.v-ecigs.com/tfa-flavor-percentage-recommendations/)
#vg="1.261"
#pg="1.036"

• Default saved recipes directory:

recipe="$HOME/Documents/Recipes/vape_recipes.txt"

• Default temporary directory:

tmp="/tmp/vapecalc"
tmp2="/tmp/vapecalc_flavours"

• Displayed text color options (from linuxhandbook):

## Black
b="\033[00;30m"

## Dark gray
lb="\033[01;30m"

## Light Gray
ly="\033[00;37m"

## Red
r="\033[00;31m"

## Light Red
lr="\033[01;31m"

## Green
g="\033[00;32m"

## Light Green
lg="\033[01;32m"

## Brown/Orange
o="\033[00;33m"

## Yellow
lo="\033[01;33m"

## Blue
u="\033[00;34m"

## Light blue
lu="\033[01;34m"

## Purple
p="\033[00;35m"

## Light Purple
lp="\033[01;35m"

## Cyan
c="\033[00;36m"

## Light Cyan
lc="\033[01;36m"

## White
w="\033[01;37m"

## End
e="\033[0m"

## FIXED COLOR OPTIONS

## Sed beginning
so="\x1b[1;36m"

## Sed end
se="\x1b[0m"

## License start
ls="\e[4;32m\e]8;;"

## Author start
as="\e[4;35m\e]8;;"

## Link end
le="\e]8;;\a\033[0m"

For the color options, you will need to search and replace all color values to one of the above listed values,
e.g. ${lr} (light red) to ${lg} (light green), etc...
For The ones under "FIXED COLOR OPTIONS" you simply need to change the value itself. You can use the colors above as reference, e.g.:

From 
## Sed beginning (default is Light Cyan)
so="\x1b[1;36m"
to 
so="\x1b[1;32m" (Light Green)

By default if no arguements are passed it will start in calculator mode.
