src/openocd.c
- **MAJOR** Work: New TCL/Jim function: mem2array
- **MAJOR** Work: Redirect Tcl/Jim stdio output to remote users.
- Previously: TCL output did not go to GDB.
- Previously: TCL output did not go to TELNET
- Previously: TCL output only goes to control console.
- This fixes that problem.
+ Created callbacks:
+openocd_jim_fwrite()
+openocd_jim_fread()
+openocd_jim_vfprintf()
+openocd_jim_fflush()
+openocd_jim_fgets()
src/Makefile.am
- New TCL files.
- Future note: This should be more automated. As the list of
'tcl' files grows maintaning this list will suck.
src/Jim.c
- ** THIS INCLUDES A PREVIOUS PATCH I SENT EARLIER **
- that impliments many [format] specifies JIM did not support.
- Jim_FormatString() - **MAJOR** work.
- Previously only supported "%s" "%d" and "%c"
- And what support existed had bugs.
- NEW: *MANY* formating parameters are now supported.
- TODO: The "precision" specifier is not supported.
** NEW ** This patch.
- Jim_StringToWide() test if no conversion occured.
- Jim_StringToIndex() test if no conversion occured.
- Jim_StringToDouble() test if no conversion occured.
** NEW ** This Patch. Major Work.
- Previously output from JIM did not get sent to GDB
- Ditto: Output to Telnet session.
- Above items are now fixed - By introducing callbacks
new function pointers in the "interp" structure.
- Helpers that call the callbacks.
- New function: Jim_fprintf()
- New function: Jim_vfprintf()
- New function: Jim_fwrite()
- New function: Jim_fread()
- New function: Jim_fflush()
- New function: Jim_fgets()
By default: the output is to STDIO as previous.
The "openocd.c" - redirects the output as needed.
- Jim_Panic() - Send panic to both STDERR and the interps
specified STDERR output as a 2nd choice.
- Now JIM's "stdin/stdout/stderr" paramters are "void *"
and are no longer "FILE *".
src/Jim.h
- **MAJOR**
- New JIM STDIO callbacks in the "interp" structure.
- change: "stdin/stdout/stderr" are now "void *" cookies.
- New JIM stdio helper functions.
