Bug in is_name() ? was created by Salty
This is an odd one and I can't seem to figure it out.  It's present in the 2024 version on github.
Code:
500H 100M 82V > eq <worn on finger>     a leather ring <worn on finger>     a leather ring <worn around neck>   a leather gorget <worn around neck>   a leather gorget

If 'n' is a number, and 'arg' is an argument, when I try to remove/wear n.arg it fails if 'arg' is exactly four (4) characters.
Code:
500H 100M 82V > rem 2.leat You don't seem to be using a ltat. 500H 100M 82V > rem 2.lea You stop using a leather ring. 500H 100M 82V > rem 2.leath          You stop using a leather ring.

In the above example, the n.arg works unless 'arg' is 4 characters long.

Code:
500H 100M 82V > eq You are using: Nothing. 500H 100M 82V > i You are carrying: ( 2) a leather gorget ( 2) a leather ring 500H 100M 82V > wear 2.ring You don't seem to have a rgng. 500H 100M 82V > wear ring You slide a leather ring on to your right ring finger. 500H 100M 82V > wear 3.leat You don't seem to be using a ltat.

While unequipped, same behavior.  

There's only a failure on remove/wear of an n.arg when n>1 and 'arg' is exactly four characters.

This isn't game breaking whatsoever, but you can't "remove 2.ring" or "wear 2.neck"  Ring is the big issue because it's exactly 4 characters.

Any thoughts?  Please advise.

Thanks!

Something is apparently messing up the string when splitting the n. from the name. Your example shows an error using the phrase "you dont seem to have a rgng" and the same for "ltat". This seems like a bug we should be able to fix :)

I've tried to reproduce it, with no luck, using the most recent build:
Code:
464H 100M 82V (news) (motd) > eq You are using: <worn on finger>    a leather ring <worn on finger>    a leather ring <worn around neck>  a leather gorget <worn around neck>  a leather gorget 464H 100M 82V (news) (motd) > rem 2.leat You stop using a leather ring.
Anything in particular you are doing here?

Interesting.  

My test build was taken straight from github and compiled on Ubuntu 22.04.4 LTS.  

I spun up a new VM running Ubuntu 22.04.6 LTS, cloned from github, configured and compiled.  The issue remains.  The same issue is present on the clean VM running Debian 12.5

Could it be a library function causing the weirdness?

Here's my attempt. Also a raw checkout from github, in a separate directory, just my character
Code:

I am current running on a rather old instance of linux (ubuntu 22.04.1), so that might be the reason:
Code:
$ uname -a Linux thomas-c-ubuntu 6.5.0-35-generic #35~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Tue May  7 09:00:52 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
I'll try updating to a newer version and try again.

Thomas,

I appreciate the help.  I did some more digging.  Looks like it might be a linux kernel issue.  

I notice your ubuntu build is: (issue not present)
Code:
[color=#333333][size=2][font=Roboto][color=#e93f8e]Linux thomas-c-ubuntu 6.5.0-35-generic #35~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Tue May  7 09:00:52 UTC 2 x86_64 x86_64 x86_64 GNU/Linux[/color][/font][/size][/color]

My gameserver build is: (issue present)
Code:
Linux OMG 5.4.0-155-generic #172-Ubuntu SMP Fri Jul 7 16:10:02 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

ubuntu on wsl2 built as: (issue present)
Code:
Linux ALONE 5.15.146.1-microsoft-standard-WSL2 #1 SMP Thu Jan 11 04:09:03 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

debian on wsl2 is built as: (issue present)
Code:
Linux ALONE 5.15.146.1-microsoft-standard-WSL2 #1 SMP Thu Jan 11 04:09:03 UTC 2024 x86_64 GNU/Linux

Today, I built a new Ubuntu in virtualbox: (issue not present)
Code:
Linux salty-VirtualBox 6.8.0-31-generic #31-Ubuntu SMP PREEMPT_DYNAMIC Sat Apr 20 00:46:06 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

The issue is not present in your 6.5.0-35-generic or the 6.8.0-31-generic kernel, but is present in 5.4.0-155-generic and the wsl2 kernels.

edit:
Fresh VM, ubuntu server 24.04 LTS
Code:
Linux utest 6.8.0-31-generic #31-Ubuntu SMP PREEMPT_DYNAMIC Sat Apr 20 00:40:06 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux
Downloaded my modified MUD from my github, compiled and ran the test again, no issue present.

Interesting stuff.  Seems like it might be the kernel?

Thoughts?
