why not include the command 'gettxoutsetinfo'?

Hello, I am develop a safely and quickly trading platform now.

I want to fetch current total namecoins in existence, the command 'gettxoutsetinfo' show the value 'total_amount' that I want to fetch. But namecoin not support this command, why?

Namecoin (in this repository) is based on an ancient version of Bitcoin and does not keep track of the UTXO set. Thus this command is not easy to implement. There was an experimental branch that added UTXO tracking which eventually turned into an UTXO implementation for Huntercoin, but this is obsolete now.

If you want this command (and a lot more), take a look at https://github.com/domob1812/namecore. Be careful, though, this is still experimental but works fully and will be released officially in the future.

Thanks. But I just want to fetch the current total namecoins in existence, how to get this value directly in namecoin?

Thanks again.

You can just calculate it from the block height. 50 NMC per block until 210,000, then 25 NMC per block. Note that the UTXO set of Namecore gives you a slightly less number, since it knows about destroyed coins (the early-days "name fee") and expired names.
