- * The command structure is a pre-computed representation of the

- *
- * For example the script:
- *
- * puts hello
- * set $i $x$y [foo]BAR
- *
- * will produce a ScriptObj with the following Tokens:
- *
- * ESC puts
- * SEP
- * ESC hello
- * EOL
- * ESC set
- * EOL
- * VAR i
- * SEP
- * VAR x
- * VAR y
- * SEP
- * CMD foo
- * ESC BAR
- * EOL
- *
- * This is a description of the tokens, separators, and of lines.
- * The command structure instead represents the number of arguments
- * of every command, followed by the tokens of which every argument
- * is composed. So for the example script, the cmdstruct array will
- * contain:
- *
- * 2 1 1 4 1 1 2 2
- *
- * Because "puts hello" has two args (2), composed of single tokens (1 1)
- * While "set $i $x$y [foo]BAR" has four (4) args, the first two
- * composed of single tokens (1 1) and the last two of double tokens
- * (2 2).
- *
- * The precomputation of the command structure makes Jim_Eval() faster,
- * and simpler because there aren't dynamic lengths / allocations.
- *
- * -- {expand} handling --
- *
- * Expand is handled in a special way. When a command
- * contains at least an argument with the {expand} prefix,
- * the command structure presents a -1 before the integer
- * describing the number of arguments. This is used in order
- * to send the command exection to a different path in case
- * of {expand} and guarantee a fast path for the more common
- * case. Also, the integers describing the number of tokens
- * are expressed with negative sign, to allow for fast check
- * of what's an {expand}-prefixed argument and what not.
- *
- * For example the command:
- *
- * list {expand}{1 2}
- *
- * Will produce the following cmdstruct array:
- *
- * -1 2 1 -2
- *
- * -- the substFlags field of the structure --
- *
- * The scriptObj structure is used to represent both "script" objects
- * and "subst" objects. In the second case, the cmdStruct related
- * fields are not used at all, but there is an additional field used
- * that is 'substFlags': this represents the flags used to turn
- * the string into the intenral representation used to perform the
- * substitution. If this flags are not what the application requires
- * the scriptObj is created again. For example the script:
- *
- * subst -nocommands $string
- * subst -novariables $string
- *
- * Will recreate the internal representation of the $string object
- * two times.

- *--- Inline Header File Documentation ---
- * [By Duane Ellis, openocd@duaneellis.com, 8/18/8]
- *
- * Belief is "Jim" would greatly benifit if Jim Internals where
- * documented in some way - form whatever, and perhaps - the package:
- * 'doxygen' is the correct approach to do that.
- *
- * Details, see: http://www.stack.nl/~dimitri/doxygen/
- *
- * To that end please follow these guide lines:
- *
- * (A) Document the PUBLIC api in the .H file.
- *
- * (B) Document JIM Internals, in the .C file.
- *
- * (C) Remember JIM is embedded in other packages, to that end do
- * not assume that your way of documenting is the right way, Jim's
- * public documentation should be agnostic, such that it is some
- * what agreeable with the "package" that is embedding JIM inside
- * of it's own doxygen documentation.
- *
- * (D) Use minimal Doxygen tags.
- *
- * This will be an "ongoing work in progress" for some time.
