When you're like, "I want this number to have a leading zero but I can't remember how it works" so you look in up in format strings but then you want to test it. So you open a console and type:
$ dnformat "{0:D2}" int:3
03
Yaaay. Now you know.
For the help text, run
$ dnformat /?
Which displays this:
Usage:
dnformat format type1:param1,type2:param2...
Examples:
dnformat "hello {0}" string:world
dnformat "{0:P} glue" float:0.05
dnformat "{0:X} {0:X08}" int:37295
The first argument is a format string, like you would pass to String.Format or to Console.WriteLine. It's best to put this in speech marks to group it as one argument. After that, pass your params in the format type:value as shown in examples above.
The software internally allows 'timespan' as a type but it's not really supported because the command line parser splits on ':', which makes it impossible to express a string timespan. This would require a lexical parser for command line input. Please open a pull request to implement one if you feel so inclined! ;)
