SKILL.md (first lines)
`xlim` is an array based, domain specific language. It can be executed using the `xlim` CLI utility.
Please see the README.md file in this skill for example syntax.
Some useful sub-commands
```
xlim --functions # Show all available functions
xlim --units # Print all available units
```
This is my language that I have full control over the development of.
If you run into ANY issues, hardships, or misunderstandings, you MUST inform me so that I can make the improvements.
If there a new features that you think would simplify your work, please inform me.
You should NEVER have to manually put in a "conversion constant".
When using this, you should be using the full form of engineering formulas.
For example, for chiller tonnage, the shorthand formula is often used:
```
TONS = GPM * (DT) / 24
```
The correct way to do this in xlim would be:
```xlim
flow = 100 {GPM}
dt = 10 {°F}
cp = 1 {BTU/lbm °F}
rho = 1000 {kg/m^3}
tons {tr} = flow * cp * rho * dt
```
For scratch calculations, you can pipe in input using the file name `-`
Things you have missed in the past:
- You can coerce the output unit (like the `tr` in `tons {tr} = flow * cp * rho * dt`)From mitchpaulus/dotfiles, MIT.
