Description

Gets details about the specified alias name.

You can obtain one of 31 "types" of information about the alias by specifying an "InfoType". The possible InfoTypes are:

1: What to match on (string)
2: What to send (string)
3: Script procedure name (string)
4: Omit from log (boolean)
5: Omit from output (boolean)
6: Enabled (boolean)
7: Regular expression (boolean)
8: Ignore case (boolean)
9: Expand variables (boolean)
10: Invocation count (long)
11: Times matched (long)
12: Menu (boolean)
13: Date/time alias last matched (date)
14: 'temporary' flag (boolean)
15: Alias was included from an include file (boolean)
16: Group name (string)
17: Variable name to set (string)
18: Send-to location (long)
19: 'keep-evaluating' flag (boolean)
20: Sequence number (long)
21: 'echo alias' flag (boolean)
22: 'omit from command history' flag (boolean)
23: User option value (long)
24: Number of matches to regular expression (most recent match) (long)
25: The string we matched against (last alias text matched against) (string)
26: Executing-script flag (boolean)
27: Script is valid flag (boolean)
28: Error number from PCRE when evaluating last match (long), zero if none
29: 'one shot' flag (boolean)
30: Time taken (in seconds) to test aliases (including un-matched ones) (double)
31: Number of attempts to match this alias (long)

101: Wildcard %1 from last time it matched
102: Wildcard %2 from last time it matched
103: Wildcard %3 from last time it matched
104: Wildcard %4 from last time it matched
105: Wildcard %5 from last time it matched
106: Wildcard %6 from last time it matched
107: Wildcard %7 from last time it matched
108: Wildcard %8 from last time it matched
109: Wildcard %9 from last time it matched
110: Wildcard %0 from last time it matched

Other wildcards can be extracted by using GetAliasWildcard.

The word in brackets indicates the "type" of data returned.
String: a character string (eg. "north")
Boolean: TRUE or FALSE
Long: a 32-bit number

The field "invocation count" is a count of how many times the script routine was called.
The field "times matched" is a count of how many times the alias matched. These two would normally be the same, unless scripting was disabled, or there was an error in the script file.

The meanings of the "send-to" field are:

0: World
1: Command window
2: Output window
3: Status line
4: Notepad (new)
5: Notepad (append)
6: Log File
7: Notepad (replace)
8: Command queue
9: Send To Variable
10: Execute (re-parse as command)
11: Speedwalk (send text is speedwalk, queue it)
12: Script (send to script engine)
13: Immediate (send to world in front of speedwalk queue)
14: Script - after omit

If the named alias does not exist, EMPTY is returned. If the name given is invalid, NULL is returned. If the InfoType given is out of range, NULL is returned. (Use "IsEmpty" and "IsNull" to test for these possibilities).

See AddAlias for a description of the meanings of the fields.

VBscript example
world.note world.GetAliasInfo ("my_alias", 2)
Jscript example
/world.note(world.GetAliasInfo ("my_alias", 2));
PerlScript example
/$world->note ($world->GetAliasInfo ("my_alias", 2));
Python example
world.note(world.GetAliasInfo ("my_alias", 2))
Lua example
Note (GetAliasInfo("my_alias", 2))
Lua notes
Lua returns nil where applicable instead of an "empty variant" or "null variant".

The "SendTo" field can be looked up using the "sendto" table in the Lua global address space, as follows:

sendto.world = 0
sendto.command = 1
sendto.output = 2
sendto.status = 3
sendto.notepad = 4
sendto.notepadappend = 5
sendto.logfile = 6
sendto.notepadreplace = 7
sendto.commandqueue = 8
sendto.variable = 9
sendto.execute = 10
sendto.speedwalk = 11
sendto.script = 12
sendto.immediate = 13
sendto.scriptafteromit = 14
Returns The specified information about the alias, as described above.
An EMPTY variant, if the alias does not exist.
A NULL variant if the alias name is invalid.
A NULL variant if the InfoType is not a valid type.
