From: oharboe Date: Sun, 6 Jul 2008 19:17:43 +0000 (+0000) Subject: src/helper/configuration.h X-Git-Tag: v0.1.0~542 X-Git-Url: https://review.openocd.org/gitweb?p=openocd.git;a=commitdiff_plain;h=dc796a209113c3fdc27de0211edcaa67faed7b5f src/helper/configuration.h - Log output handlers now get a "const char *line" - Added "const" to parameter. src/helper/command.c src/helper/command.h - New function: 'command_output_text()' - Log output handlers now get a "const char *line" src/helper/options.c - Log output handlers now get a "const char *line" src/server/telnet_server.c - DO not transmit NULL bytes via TELNET. - Log output handlers now get a "const char *line" src/server/gdb_server.c - Log output handlers now get a "const char *line" *** THIS INCLUDES PORTIONS OF A PATCH FROM Oyvind sent previously to the mailing list for TCL users try src/target/target.c *** THIS INCLUDES PORTIONS OF A PATCH FROM Oyvind sent previously to the mailing list for TCL users try src/target/target.h *** THIS INCLUDES PORTIONS OF A PATCH FROM Oyvind sent previously to the mailing list for TCL users try 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. git-svn-id: svn://svn.berlios.de/openocd/trunk@755 b42882b7-edfa-0310-969c-e2dbd0fdcd60 --- diff --git a/src/Makefile.am b/src/Makefile.am index 462b5ee4d0..924040e615 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -81,4 +81,20 @@ openocd_LDADD = $(top_builddir)/src/xsvf/libxsvf.a \ -nobase_dist_pkglib_DATA = tcl/commands.tcl +nobase_dist_pkglib_DATA = \ + tcl/commands.tcl \ + tcl/bitsbytes.tcl \ + tcl/chip/atmel/at91/aic.tcl \ + tcl/chip/atmel/at91/at91sam7x128.tcl \ + tcl/chip/atmel/at91/at91sam7x256.tcl \ + tcl/chip/atmel/at91/pmc.tcl \ + tcl/chip/atmel/at91/rtt.tcl \ + tcl/chip/atmel/at91/usarts.tcl \ + tcl/cpu/arm/arm7tdmi.tcl \ + tcl/cpu/arm/arm920.tcl \ + tcl/cpu/arm/arm946.tcl \ + tcl/cpu/arm/arm966.tcl \ + tcl/memory.tcl \ + tcl/mmr_helpers.tcl \ + tcl/readable.tcl + diff --git a/src/helper/command.c b/src/helper/command.c index ed0a82e621..386572ed94 100644 --- a/src/helper/command.c +++ b/src/helper/command.c @@ -621,7 +621,7 @@ int command_print_help(command_context_t* context, char* name, char** args, int return command_print_help_match(context, context->commands, name, args, argc);
