54d6330b78 command: print BUG warning when usage is missing
These error messages will prompt patches to be submitted for missing
.usage or empty fields. All of the below must be resolved before next
release.

The Jim defined commands are excluded from this checklist because the
help text can be set later than during command registration.

strlen(.usage) == 0 means that the command expects no arguments.

Updates to this patch in Gerrit to fix problems below are most
welcome. Anyone can push updated versions of a patch to Gerrit. If
there are no further updates to this patch within a week, it will be
pushed to the master branch to prompt more fixes.

These were caught by launching OpenOCD.

ac86f4ccba command: capture command now handles both types commands
Commands that output progress output and no return value
will have the progress output captured.

Commands that do not output progress output(tcl commands)
will return the tcl return value instead.

The advantage here is that it is no longer necessary to
consider which command one is capturing, it works for
either.

Example #1: capture progress output:

set foo [capture help]

Example #2: capture tcl return value

set foo [capture {set abc def}]

127f9da4fe don't add confusing source info to Jim
When an interactive command fails, the Jim stack trace prints references to
the line in "command.c" where the interpreter was invoked. Since that
location has no relation to the actual command that failed, the information
serves only to add confusion.

By not adding the useless source info to Jim the noise can be reduced,
while still printing a useful trace for nested commands.

b3bf1d12b2 streamline and document helptext mode displays
Most commands are usable only at runtime; so don't bother saying
that, it's noise.  Moreover, tokens like EXEC are cryptic.  Be
more clear: highlight only the commands which may (also) be used
during the config stage, thus matching the docs more closely.
There are

 - Configuration commands (per documentation)
 - And also some commands that valid at *any* time.

Update the docs to note that "help" now shows this mode info.

This also highlighted a few mistakes in command configuration,
mostly commands listed as "valid at any time" which shouldn't
have been.  This just fixes ones I noted when sanity testing.

bc9ae74073 improve command_done() API and docs
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.

Fixes a memory leak of the returned command_name() string.

fd343bea7f refactor command mode detection
Splits the check for a command's ability to run into a helper.

This also fixes a bug whereby commands that specified COMMAND_EXEC
were allowed to run during the configuration stage.  This allowed
problematic commands to be called before 'init', defeating the intention
of specifying that command mode.  With this change, the run_command()
helper denies access to handlers that should run only after 'init'
during the configuration stage.

933b4579f0 add command private data setter/accessor
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.

Also allows introspection of the mode required for commands.

89fa493a3b remove unknown handler
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.

df22f0f9ca improve command handler wrapper script
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.

37dd5a685a add 'command type' introspective handler
Adds the 'command' group handler, with the 'type' command producing
a string that tells whether the given command is 'native' (for Jim-based
command handlers), 'simple' (for simple built-in commands), 'group'
for command group placeholders, and 'unknown' if not found in the
command registration tables (e.g. core built-ins functions).
