From bbe7110f42e96f9c56f9eea7819bf9b287dbe16f Mon Sep 17 00:00:00 2001 From: oharboe Date: Tue, 19 Aug 2008 11:49:48 +0000 Subject: duane ellis: (A) a new concept called "Name Value Pair" or NVP, in simple terms: Think: "String" and "Value". There can be many strings - all related to a single value, for examle: "T", "t", "y", "1", "yes", all can represent "truth", the reverse mapping is more simplistic - the first matching number wins. (B) a new "getopt" like feature for Jim - that simplifies argument parsing in complex functions, normally this would be used in conjunction with either an NVP table of options, or a more simpler Enumeration table. In contrast to the GNU "getopt" package, this is more of a "object model or code oriented" solution then a pure data structure used by GNU getopt, or the main stream Tcl/Tk option processing. git-svn-id: svn://svn.berlios.de/openocd/trunk@936 b42882b7-edfa-0310-969c-e2dbd0fdcd60 --- src/helper/jim.c | 459 ++++++++++++++++++++++++++++++++++++++++++++++++++++++- src/helper/jim.h | 337 +++++++++++++++++++++++++++++++++++++++- 2 files changed, 792 insertions(+), 4 deletions(-) diff --git a/src/helper/jim.c b/src/helper/jim.c index 1a35b32b..02d0e0d1 100644 --- a/src/helper/jim.c +++ b/src/helper/jim.c @@ -2510,9 +2510,9 @@ int qsortCompareStringPointers(const void *a, const void *b) } int Jim_GetEnum(Jim_Interp *interp, Jim_Obj *objPtr, - const char **tablePtr, int *indexPtr, const char *name, int flags) + const char * const *tablePtr, int *indexPtr, const char *name, int flags) { - const char **entryPtr = NULL;
