@Joerg-L Thank you for creating the issue! Indeed, different currencies may have different formats and currently we use a naive approach for simplicity.

I wonder if having a setting for locale like infracost configure set locale de_DE (or via env var) makes more sense. This way CLI could automatically figure out how to represent the numbers (and maybe even text translation in future).

Would you find it more useful instead of manually providing a format template? I can see an extra complexity with parsing this and handling incorrect formats, but maybe I'm missing a use case here.

@vdmgolub I'm completely fine with your approach.

Related to text translation:
if that comes any time in future, an option to disable that would make sense too, I would think.

Oh! That's right, I guess many teams in engineering would use English language for communication. But it seems like you would still prefer to see the costs in your local currency AND format. Very interesting! :) I'll bring this topic to the team to discuss what would work better in a long run.

Thank you for bringing this up! We'll update the issue when we have more details. 👍

We use the go-money package and that already has a template mechanism for positioning the currency symbol. I'm guessing it wouldn't be too difficult to let users set an alternate template.

@tim775 It's not just the symbol position, in Germany comma delimits the decimal part, and dot is a thousands separator. That is why I thought about introducing locale notion.

@Joerg-L I've updated the description with a proposed solution. We thought the ENV var would be a good start for now. It's open for community contributions. If you feel like implementing it, please leave a comment and I'll assign it to you. :)

Thanks again for creating the issue! It should be a nice enhancement for the app. :)

@vdmgolub thanks for that update.
I have just replace den $ with € in your update....

If I would have any clue in devloping such things, I would like to contribute, to be honset, I don't have a clue.
I'm just an IT guy who is creating terraform configurations.

@Joerg-L No worries at all, was checking in case you're interested to try new things :)

Oops, I need to elaborate it better in the description: the $ is a fixed symbol here, like a placeholder for the currency character. Having a predefined format with known values makes it easy to parse: the parser would know that the thousands delimiter is always between 123 and 456, same for the decimal point - between 456 and 7*. The 7890 would show the count of the fraction size - 4 digits, and $ will highlight where the currency character should be located - go-money package already knows how to replace it with the right one. I'll update the description :)

Hi, I am working on this, please assign it to me.

Custom currency and formatting support is now live in the v0.10.12 release. Thanks @fatihtokus for your contribution.
