* command context: fix errors when running certain commands on startupØyvind Harboe2010-05-051-0/+4
| | | | | | | | | | | Various commands, e.g. "arm mcr xxxx" would fail if invoked upon startup since it there was no command context defined for the jim interpreter in that case. A Jim interpreter is now associated with a command context(telnet, gdb server's) or the default global command context. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

* change #include "types.h" to <helper/types.h>Zachary T Welch2009-12-031-1/+1
| | | | | | | | | | | | Changes from the flat namespace to heirarchical one. Instead of writing: #include "types.h" the following form should be used. #include <helper/types.h> The exception is from .c files in the same directory.

* command: the Jim interpreter can now be provided rather than createdØyvind Harboe2009-12-011-2/+4
| | | | | | | In embedded hosts, the Jim interpreter can come from the existing context rather than be created by OpenOCD. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* remove interp global variable!Zachary T Welch2009-11-301-1/+1
| | | | | | | Finish removing references to the 'interp' global variable from the command module, encapsulating all reference via command_context. Eliminates use of the global entirely, so it can be removed. Hurrah!
* do not extern 'interp' from command.cZachary T Welch2009-11-301-2/+1
| | | | | Adds 'interp' field to command_context, chasing the few remaining references to the global variable outside of the command module.
* move improperly located documentationZachary T Welch2009-11-301-15/+17
| | | | | Somehow, the comment block for command handlers ended up associated with the output_handler. Move it to the command_handler_t declaration.
* improve command_done() API and docsZachary T Welch2009-11-301-2/+15
| | | | | | | | | | | | | | | | | | command_done() does not need to return an error, but it needed Doxygen comment. Provide some for copy_command_context as well. Note: this audit revealed some potential bugs with the command context implementation. There was a reason that commands were added at the end of the list. Shallow copying of command_context means that the list is shared between them. And commands added at the top-level before the pre-existing commands will not be available in the shared context as they were before. Yikes! Fortunately, this does not seem to occur in general use, as 'add_help_text' gets registered in startup.tcl and claims the first slot in my own test cases. Thus, it seems that we have been masking the issue for now, but it shows the need for further architectural improvement in the core command module.
* add command private data setter/accessorZachary T Welch2009-11-281-0/+23
| | | | | | | | | | Presently, commands registration taks a static handler data pointer. This patch adds support for commands that require a dynamic pointer, such as those registered in a dynamic context (e.g. subcommands for a user-created 'foo.cpu' command). The command_set_handler_data will update a command (group) to use a new context pointer, while the CMD_DATA macro allows command handlers to access the value. Jim handlers should find this value in interp->cmdPrivData.
* add jim_handler to command_registrationZachary T Welch2009-11-241-3/+4
| | | | | | Adding jim_handler field to command_registration allows removing the register_jim helper. All command registrations now go through the register_command{,s}() functions.
* add public API for locating commandsZachary T Welch2009-11-241-0/+5
| | | | | Allow other modules to find a command, primarily for the purpose of registering and unregistering subcommands.
* add command registration chainingZachary T Welch2009-11-241-2/+13
| | | | | | | | | Adds the ability to chain registration structures. Modules can define a command with the 'chain' and 'num_chain' fields defined in their registration table, and the register_commands() function will initialize these commands. If the registration record creates a new command, then the chained commands are created under it; otherwise, they are created in the same context as the other commands (i.e. the parent argument).
* add command usage, separate from helpZachary T Welch2009-11-241-0/+3
| | | | | | Adds the usage command, to display usage information for commands. The output for this command will remain erronenously empty until commands are updated to use these new coventions.
* add register_commands for batch registrationZachary T Welch2009-11-241-0/+19
| | | | | | The register_commands API takes multiple commands in one call, allowing modules to declare and pass a much simpler (and more explicit) array of command_registration records.
* add struct command_registrationZachary T Welch2009-11-241-16/+35
| | | | | | | | | Add a structure to encapsulate command registration information, rather than passing them all as parameters. Enables further API changes that require additional required or optional parameters. Updates the register_command API and COMMAND_REGISTER macro to use it, along with their documentation.
* add COMMAND_REGISTER macroZachary T Welch2009-11-241-0/+4
| | | | | | | | Provides a migration path for the widely used register_command API, which needs to be updated to provide new functionality. This macro allows the API to change without having to update all of its callers at the same time.
* improve 'help' commandZachary T Welch2009-11-201-0/+1
| | | | | | | | | | | 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).
* refactor command registrationZachary T Welch2009-11-201-5/+46
| | | | | | | | | Refactors the command registration to use helpers to simplify the code. The unregistration routines were made more flexible by allowing them to operate on a single command, such that one can remove all of a commands children in one step (perhaps before adding back a 'config' subcommand that allows getting the others back). Eliminates a bit of duplicated code and adds full API documentation for these routines.
* remove fast command and jim_global_longZachary T Welch2009-11-181-4/+0
| | | | | | | | Removing the fast command eliminates the fast_and_dangerous global, which was used only by arm7_9_common as an initializer. The command is not called in the tree; instead, more explicit commands are used. The jim_global_long function was not used anywhere in the tree.
* change all bool parsers to accept any valueZachary T Welch2009-11-181-3/+2
| | | | | | | | | This patch changes the behavior of all boolean parsing callers to accept any one of "true/enable/on/yes/1" or "false/disable/off/no/0". Since one particular pair will be most appropriate in any given situation, the specific macros should continue to be used in order to display the most informative error messages possible.
* add handle_command_parse_bool command helperZachary T Welch2009-11-181-6/+9
| | | | | | | | | Rewrite arm11_handle_bool to provide a generic on/off command helper. Refactors COMMAND_PARSE_BOOL to use new command_parse_bool helper, which gets reused by the new command_parse_bool_any helper. This later helper is called by the new command helper function to accepts any on/off, enable/disable, true/false, yes/no, or 0/1 parameter.
* add COMMAND_PARSE_BOOL macro and friendsZachary T Welch2009-11-181-0/+28
| | | | | | | | | | | | Adds several macros similar to COMMAND_PARSE_NUMBER, but for parsing boolean command arguments. Two flavors are provided to provide drop-in compatibility with existing code, allow for the elimination of a lot of code bloat while improving the error checking and reporting. COMMAND_PARSE_ON_OFF parses "on"/"off" command parameters. COMMAND_PARSE_ENABLE parses "enable"/"disable" command parameters. Both print the error and return an error out of the calling function.
* pass startup_tcl to command_initZachary T Welch2009-11-181-1/+4
| | | | | Removes external linkage from helper module, making the startup code a parameter to a new command context's initialization routine.
* add CMD_NAME variable in command_invocationZachary T Welch2009-11-171-1/+2
| | | | | Update CMD_NAME from its migratory home in CMD_ARGV[-1] to cmd->name. Allows CMD_ARGV++ idiom to be used safely in command handlers.
* add struct command_invocation for COMMAND_HANDLERZachary T Welch2009-11-171-6/+15
| | | | | | | | | | Adds the command_invocation structure to encapsulate parameters for all COMMAND_HANDLER routines. Rather than passing several arguments to each successive subroutine, a single pointer may be passed around. Changes the CMD_* macros to reference the new fields. Updates run_command to create an instance and pass it to the handler.
* command_handler: change 'cmd_ctx' to CMD_CTXZachary T Welch2009-11-171-1/+1
| | | | Convert all command handler 'cmd_ctx' parameter usage with CMD_CTX.
* add more command_handler conversion macrosZachary T Welch2009-11-171-1/+16
| | | | | | | | | Add additional macros to allow command handling to be migrated easily: CMD_CTX, CMD_ARGC, and CMD_ARGV. Updates CMD_NAME to use CMD_ARGV. In addition to making the remaining patches of this series cleaner, this introduces easily sed-able symbols that could allow us to retire these once the command handler infrastructure matures (i.e. pre-1.0).
* use Jim_CmdProc in jim_registerZachary T Welch2009-11-161-1/+2
| | | | The jim_register command just needed to use the type defined by jim.h.
* command_t -> struct commandZachary T Welch2009-11-131-9/+9
| | | | Remove misleading typedef and redundant suffix from struct command.
* command_context_t -> struct command_contextZachary T Welch2009-11-131-19/+19
| | | | Remove misleading typedef and redundant suffix from struct command_context.
* command_handler_t: make cmd an indirect parameterZachary T Welch2009-11-131-3/+3
| | | | | This patch removes 'cmd' from the list of direct parameters, moving that pointer to args[-1] (by way of the new CMD_NAME macro).
* command_handler_t: make args parameter constZachary T Welch2009-11-131-1/+1
| | | | | This patch prevents command handlers from modifying the strings passed in the 'args' array.
* command_handler_t: make cmd parameter constZachary T Welch2009-11-131-1/+1
| | | | | Prevents the command name from being modified in command handlers. Again, this has cascading effects, but the patches are fairly minimal.
* command_handler_t: make argc unsignedZachary T Welch2009-11-131-1/+1
| | | | | | The number of command arguments will always be 0 or more, so use the right type in handlers. This has a cascading effect up through the layers, but the new COMMAND_HANDLER macros prevented total chaos.
* add CMD_NAME macro for command handlersZachary T Welch2009-11-131-0/+6
| | | | | By introducing the CMD_NAME macro, this parameter may be integrated as args[-1] in command.[ch], without touching any other call sites.
* add command_handler_t typeZachary T Welch2009-11-131-4/+5
| | | | | | This patch adds new typedefs for command handler callback functions. Users of this type signature were updated to use these new types. It uses the new __COMMAND_HANDLER macro to prevent duplication.
* add COMMAND_HANDLER and COMMAND_HELPER macrosZachary T Welch2009-11-131-0/+42
| | | | | | | | | | | | | | | | | The COMMAND_HANDLER and COMMAND_HELPER macros allow commands to be defined in a manner that decouples them from the exact order and type of their parameters. Once converted, incremental changes to the command handler type can be addressed in incremental patches that do not need to touch the entire tree. These macros' implementation, __COMMAND_HANDLER, is used to define the new command_handler_t type, and additional patches will use it to derive new macros to define extended command types (e.g. flash, nand, pld). The CALL_COMMAND_HANDLER provides a means of calling helpers or nested handlers from withing a command handler. This patch uses C99 varadic macro expansion. Please report compilers that cannot handle this code.
* add command_output_handler_tZachary T Welch2009-11-131-3/+8
| | | | | Add a typedef for command output handler function type, simplifying the appearance of functions that use it and eliminating duplicate code.
* add command_name helperZachary T Welch2009-11-111-0/+10
| | | | | | | The command_name function returns a malloced string for a given command and its parents. This can be used to display a message to the user, but it is used internally to handle registration and syntax errors. This helps permit arbitrary command nesting.
* script_debug(): improve typesZachary T Welch2009-11-111-1/+2
| | | | Use unsigned type for number of arguments.
* src/helper: wrap and clean headers.Zachary T Welch2009-11-091-15/+26
| | | | | Remove all useless 'extern' keywords from function prototypes. Wraps long lines for readability.
* Add macro for parsing numeric command arguments.Zachary T Welch2009-11-051-0/+21
| | | | | | | | This helper eliminates significant amount of redundant code in command handler functions throughout the system. It wraps the lower-level parse_* macros to implement a policy for reporting parse errors to the active command context (cmd_ctx). If errors do occur, this macro causes the calling function to abort with the proper return code.
* corrective fix for MinGW GNU C99 printf complianceRedirect 'Slash' NIL2009-10-191-3/+4
| | | | | | | | | | | | | | Compilation on cygwin, using gcc v3 with option -mno-cygwin, currently produces a large number of the following warnings: warning: `gnu_printf' is an unrecognized format function type These have been introduced with the recent MinGW GNU C99 printf compliance patch, as gnu_printf was only introduced with gcc v4.4 and is not recognized with earlier versions. The attached fix adds gcc version detection to the previous patch to avoid the problem.
* More MinGW C99 printf complianceRedirect 'Slash' NIL2009-10-171-3/+11
| | | | | | | | Passing "--std=gun99" is unfortunately not sufficient to make current MinGW compilers conform with respect to checking printf format strings. (The C runtime seems not to have problems.) Fix by using a "gnu_printf" format specifier not "printf".
