* make syntax errors respond with 'usage'Zachary T Welch2009-11-301-1/+1
| | | | | | The 'help' text will become more verbose, so its entire text will be far more than desired when you only borked your syntax. The usage still allows the commands to be looked up for more help.
* remove unknown handlerZachary T Welch2009-11-281-2/+2
| | | | | | | | | | | | | | Updates command registration to provide top-level handlers for all commands, rather than falling back onto the 'unknown' command. Instead, that same handler is registered for placeholders, providing the same functionality under the root verb command name instead. This permits users to implement their own 'unknown' function, and it resolves some mind-bending breakage related to function object lookup while recursing. Changes 'ocd_bounce' to call 'ocd_command' and 'ocd_help' from the wrapper directly, rather than bouncing through their wrappers. This prevents endless recursion caused by the above changes, whereby the 'command' wrapper's type check would blow the stack to hell and gone.
* improve command handler wrapper scriptZachary T Welch2009-11-281-0/+24
| | | | | | | | | | Adds 'ocd_bouncer' in startup.tcl that is called as a helper for all command handlers, shrinking the embedded C wrapper to a mere stub. Jim handlers are called directly, simple handlers get called with the wrapper to capture and discard their output on error, and placeholders call help directly (though the unknown handler still does this too). It attempts to improve the quality of the error messages as well.
* improve usage and help command outputZachary T Welch2009-11-241-34/+0
| | | | | Rewrite formatting code in C, removing last remenants of TCL help code. Sinificantly improves the readability by using smarter indent and wrap.
* allow scripts to update usage informationZachary T Welch2009-11-241-3/+4
| | | | | | The add_usage_text command uses the same C handler, which was updated to support its new polymorphic role. This patch updates the two script commands that needed this support: 'find' and 'script'.
* rewrite 'unknown' command dispatching in CZachary T Welch2009-11-241-17/+0
| | | | | Rewrite the magical 'unknown' command in C as a Jim handler, allowing it to dispatch commands to any level in the tree.
* improve startup tcl scriptsZachary T Welch2009-11-241-4/+0
| | | | | Fix a couple of layering violations missed in the last round. Add missing comment headers.
* add add_help_text command handlerZachary T Welch2009-11-201-15/+1
| | | | | | | | | | Rewrite means for scripts to register help text for commands. These cause the new commands to be stored in the command heirarchy, with built-in commands; however, they will never be invoked there because they do not receive a command handler. The same trick is used for the Jim commands. Remove the old helpers that were used to register commands.
* improve 'help' commandZachary T Welch2009-11-201-18/+0
| | | | | | | | | | | Rewrites 'help' command in C, using new 'cmd_help' for display. Adds the built-in 'help' COMMAND_HANDLER to provide better output than the TCL-based script command (e.g. heirarchical listing of commands). The help string is stored in the command structure, though it conitnues to be pushed into the Jim environment. The current idiomatic usage suggests the addition of a usage field as well, to provide two levels of detail for users to consume (i.e. terse usage list, or verbose help).
* factor help script command into partsZachary T Welch2009-11-201-28/+34
| | | | | | | | Creates a helper function, cmd_help, which displays the help string for a single command. Presently, it is called from the loop in help. The routine has been extended to allow indentation of command groups, so an improved help command can improve the display of information.
* split startup.tcl file across modulesZachary T Welch2009-11-181-230/+1
| | | | | | | Moves definitions for each layer into their own file, eliminating layering violations in the built-in TCL code. Updates src/Makefile.am rules to include all files in the final startup.tcl input file, and others Makefile.am rules to distribute the new files in our packages.
* ARM: "armv4_5" command prefix becomes "arm"David Brownell2009-11-161-0/+9
| | | | | | | | | | Rename the "armv4_5" command prefix to straight "arm" so it makes more sense for newer cores. Add a simple compatibility script. Make sure all the commands give the same "not an ARM" diagnostic message (and fail properly) when called against non-ARM targets. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* wrap help commandZachary T Welch2009-11-111-9/+17
| | | | Use continuation characters to wrap the help command into 80 columns.
* doc updates to match "help" betterDavid Brownell2009-10-141-52/+5
| | | | | | | | | | | | | | | | | | | This makes the documentation a closer match to "help" output: - "pathmove" somehow was not documented in the User's Guide - "jtag_nsrst_assert_width" and "jtag_ntrst_assert_width" are new; both needed descriptions. - Removed two undocumented and fairly useless script mechanisms: * production/production_info/production_test ... using it, requires replacing everything; so having it adds no value. * cpu ... way out of date; hopeless to keep that current Note that anyone using that "production" stuff already defines their own procedures, and can keep using them with no change. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* add overridable Tcl "init_reset"David Brownell2009-10-081-8/+22
| | | | | | | | | | | This abstracts the "jtag arp_init-reset" call into a method called from OpenOCD startup and reset processing. Platforms which have different requirements for how such hard resets must be performed can now override "init_reset" instead of needing to rebuild custom hacked versions of the server.

| | | | | | | | | | | | | | | | | | | | | from pre/post_reset event scripts. Adding the second parameter was a mistake seen in retrospect. this gives precise control in post_reset for *when* the post reset speed is set. The pre_reset event was added *after* the second parameter to jtag_khz/speed - the target implementations no longer gets involved in the reset mode scheme. Either they reset a target into a halted mode or not. target_process_reset() detects if the reset halt failed or not. - tcl target event names are now target_N_name. Mainly internal at this early stage, but best to get the naming right now. - added hardcoded reset modes from gdb_server.c. I don't know precisely what these defaults should be or if it should be made configurable. Perhaps some hardcoded defaults will do for now and it can be made configurable later. - bugfix in cortex_m3.c for reset_run_and_xxx? - issue syntax error upon obsolete argument in target command instead of printing message that will surely drown in the log git-svn-id: svn://svn.berlios.de/openocd/trunk@849 b42882b7-edfa-0310-969c-e2dbd0fdcd60
