Extremely overengineered currency converter. You can download is as an Alfred workflow or a CLI application on the releases page.
Rates are acquired from currencyconverterapi.com (you should get their free API key to use this tool). Rates are cached locally for the next hour, since free API updates the rates hourly.
The following format is supported
1- convert 1 unit of default source currency to default target currency.1 USD|$1- convert 1 USD to default target currency.1 in EUR|1 to €- convert 1 unit of default source currency to euro.1 usd eur- convert 1 USD to EUR (you can omit "to"/"in" if both currencies are present)
You can use standard 3-letter currency code or some currency symbols. See currency-converter --list for the full list.
This currency converter also supports mathematical notation (in order of precedence):
()
a^b (power)
* /
+ -
+X% -X% (percent addition/subtraction)
Numbers could use custom --dec-sep characters from the list ., `' as decimal separators. All other characters from the list are ignored and could be used to aid with readability.
Example: $ (1' 000' 000/2 000 + 25% - 5*2)^1.01 in eur
