Mirc Script

mIRC script is the scripting language included with mIRC, an IRC client.

Primary uses

  • Bots that provide automated IRC channel management, trivia or other games, and other desired functions for chatters
  • Commands that save typing or otherwise simplify life on IRC (such as automatically identifying as the owner of a nickname)

Other uses

Script storage

Scripts are stored in files, usually with a .mrc or .ini file extension. Multiple script files can be loaded at one time.

Items that are scriptable

  • Aliases are subprograms. Aliases that return a value are known as custom identifiers. Aliases are called from the command line or other parts of a script.
  • Popups are scripted context menu items. Popups are called when they are selected by the user.
  • Remotes are event-handling scripts. Remotes are called when the event they handle occurs.

Data storage

Files

  • Scripts can read from and write to files

Binary variables

  • Contain unlimited (8192 bytes prior to mIRC 6.1) raw data
  • Globally accessible via commands and identifiers
  • Automatically disappear when script returns control to mIRC (and not to another part of a script)
  • Prefixed with & (&VariableName)

Hash tables

  • Contain keys (which are identical to binary variables except with no prefix)
  • Globally accessible via commands and identifiers
  • Automatically disappear when exiting mIRC
  • Not prefixed

Global variables

  • Contain 945 bytes of space-delimited data (variable names use up that space: %a can store up to 944 bytes of data and %ace can store up to 942 bytes of data)
  • Cannot store NUL (ASCII 0) or consecutive spaces
  • Globally accessible
  • Do not automatically disappear (stored automatically in a mIRC initialization file)
  • Prefixed with % (%VariableName)

Local variables

  • Contain 945 bytes of space-delimited data (variable names use up that space: %a can store up to 944 bytes of data and %ace can store up to 942 bytes of data)
  • Cannot store NUL (ASCII 0) or consecutive spaces
  • Accessible only by the alias that created them
  • Only existing in the context of the alias that created them
  • Prefixed with % (%VariableName)

Code Example

Theser codes are in the aliases script format. On the remote script, the commands should be preceeded by the word "alias". Here is the Hello World code example:
  hello {   echo -a Hello }  
Here is an example to count to ten:
  ten {   var %x = 1   while (%x <= 10) {     echo -a %x     inc %x   } }
