[2.09] CL Parser doesn't know about new alias
|
When a new alias is created and immediately used in the same command line entry the parser sends the alias along as though the alias didn't exist.
1. Launch CMud
2. Close Sessions Window (ESC)
3. Enter at the command line
| Code: |
#ALIAS abc {#SAY yes}
abc |
|

I've seen this as well - I wondered if it was a threading problem, the alias being called before the database has been updated, but
#alias abc {#say yes}
#wait 5000
abc
fails as well. |

Confirmed. I even this to see if it made a difference, but it did not.
| Code: |
#ALIAS abc {#SAY yes}
abc
#echo john
abc |
[edit] Fang beat me to it. |

I think it's because the whole command line is compiled in one batch, and so the alias doesn't really exist when it is being called. Zugg will confirm though.

Yes, Seb is correct. The entire command line is compiled at once, and at compile time the alias doesn't exist yet.
This is really a side-effect of the "smart" command line. When CMUD is compiling the command line, if it sees something that isn't an alias, it assumes that this is something you want to send to the MUD. In normal script execution, CMUD still treats the unknown string as a possible alias reference until run-time. But on the command line, any unknown string is sent to the MUD. |
