Maybe we can also add support for string to integer conversion and vice-versa.

This will help a lot with customization based on status code.

Also is this PR ready, or still in draft? @deefdragon

In case u are not getting time to wrap this up, maybe I can continue on finishing and adding more Template functions, as this seems to be a good change for better customization support for custom config templates.

Also I feel it would be best to introduce strig as a dep to this project instead of us creating our own duplicate template functions.
We can always merge maps. So the following should work and be simpler compared to us maintaining the same code.

import "github.com/Masterminds/sprig/v3"
// ...
maps.Copy(TemplateFunctions, sprig.FuncMap())

Edit:
I do see that we can get conflicts between duplicate keys, but feels like if that happens it's high likely that the conflicted functions are doing the same thing.

For now, since I need this change in my project, I'll fork this project.

But I'd love it if these changes can get reviewed/approved 💯

@jamietanna Maybe you can help here.

This PR has been open for a year now.
I can work on it in case this has become stale and isn't worked upon anymore.

Or maybe you have better ideas around this?

Please feel free to take over. Unfortunately life has gotten in the way of me keeping up with the prs I have open, and my fork that just imports sprig as a dep has worked well enough for me that I've not had a push to work on this.

U can close this one, if u aren't going to contribute anymore.
I'll create a separate PR, after testing 👍🏽
