125 * The Quake command-line is super basic. It can be entered in the console
126 * or in config files. A semicolon is used to terminate a command and chain
127 * them together. Otherwise, a newline delineates command input.
129 * In most engines, the Quake command-line is a simple linear text buffer that
130 * is parsed when it executes. In Darkplaces, we use a linked list of command
131 * input and parse the input on the spot.
133 * This was done because Darkplaces allows multiple command interpreters on the
134 * same thread. Previously, each interpreter maintained its own buffer and this
135 * caused problems related to execution order, and maintaining a single simple
136 * buffer for all interpreters makes it non-trivial to keep track of which
137 * command should execute on which interpreter.

1322 // - ${var !} fails expansion and executes nothing if

1325 // for example, if $x has the value timelimit, ${$x} will return
1326 // the value of $timelimit
1327 // - when expanding an alias, the special variable name $* refers
1328 // to all alias parameters, and a number refers to that numbered

1330 // parameter is $1 and so on; as a special case, $* inserts all

1332 // pass all parameters around. All parameters starting from $n

1338 // dollar signs have no unwanted bad side effects. However, this needs to

1340 // alias foo "set x NEW; echo $x"

1344 // alias foo "set x NEW; foo2"
1345 // alias foo2 "echo $x"
1347 // Also note: lines starting with alias are exempt from cvar expansion.
1348 // If you want cvar expansion, write "alias" instead:
1351 // alias foo "echo $x"
1352 // "alias" bar "echo $x"
1355 // foo will print 2, because the variable $x will be expanded when the alias
