Bruce Mitchener 13d21e9ae1 commands: Use override instead of virtual.
Summary:
This removes all uses of virtual on functions
where override could be used, including on destructors.

It also adds override where virtual was previously
missing.

Kate Stone ea671fbdff Fixed line wrapping for the "long help" content in LLDB commands. Content is now dynamically wrapped for the column width of the current terminal. Lines that begin with whitespace will be indented identically on subsequent lines to maintain formatting.
Existing commands supplying this type of help content have been reworked to take advantage of the changes.  In addition to formatting changes, content was changes for accuracy and clarity purposes.

Zachary Turner 1124045ac7 Don't #include "lldb-python.h" from anywhere.
Since interaction with the python interpreter is moving towards
being more isolated, we won't be able to include this header from
normal files anymore, all includes of it should be localized to
the python library which will live under source/bindings/API/Python
after a future patch.

None of the files that were including this header actually depended
on it anyway, so it was just a dead include in every single instance.

Enrico Granata e87764f247 Add support for custom commands to set flags on themselves
This works for Python commands defined via a class (implement get_flags on your class) and C++ plugin commands (which can call SBCommand::GetFlags()/SetFlags())

Flags allow features such as not letting the command run if there's no target, or if the process is not stopped, ...
Commands could always check for these things themselves, but having these accessible via flags makes custom commands more consistent with built-in ones

Zachary Turner 0641ca1a2d Remove ScriptInterpreterObject.
This removes ScriptInterpreterObject from the codebase completely.
Places that used to rely on ScriptInterpreterObject now use
StructuredData::Object and its derived classes.  To support this,
a new type of StructuredData object is introduced, called
StructuredData::Generic, which stores a void*.  Internally within
the python library, StructuredPythonObject subclasses this
StructuredData::Generic class so that it can addref and decref
the python object on construction and destruction.

Additionally, all of the classes in PythonDataObjects.h such
as PythonList, PythonDictionary, etc now provide a method to
create an instance of the corresponding StructuredData type.  For
example, there is PythonDictionary::CreateStructuredDictionary.
To eliminate dependencies on PythonDataObjects for external
callers, all ScriptInterpreter methods now return only
StructuredData classes

The rest of the changes in this CL are focused on fixing up
users of PythonDataObjects classes to use the new StructuredData
classes.

Enrico Granata 6f79bb2d57 Add support for Python object commands to return custom short and long help by implementing

Enrico Granata 9fe00e52d3 Bulk of the infrastructure work to allow script commands to be backed by object instances in addition to free functions
This works by creating a command backed by a class whose interface should - at least - include

def __init__(self, debugger, session_dict)
def __call__(self, args, return_obj, exe_ctx)

What works:
- adding a command via command script add --class
- calling a thusly created command

What is missing:
- support for custom help
- test cases

The missing parts will follow over the next couple of days

This is an improvement over the existing system as:
a) it provides an obvious location for commands to provide help strings (i.e. methods)
b) it allows commands to store state in an obvious fashion
c) it allows us to easily add features to script commands over time (option parsing and subcommands registration, I am looking at you :-)

Greg Clayton b547278cae Fixed an issue where you couldn't delete a user defined regex, python, or multi-word command by adding a new "command delete" command.
This new command will delete user defined regular commands, but not aliases. We still have "command unalias" to remove aliases as they are currently in different buckets. Appropriate error messages are displayed to inform the user when "command unalias" is used on removable user defined commands that points users to the "command delete" command.

Added a test to verify we can remove user defined commands and also verify that "command unalias" fails when used on a user defined command.

Greg Clayton ea508635de Have CommandObjectCommandsAddRegex inherit from IOHandlerDelegateMultiline so it will not immediately terminate after the first regular expression in "command regex <name>" commands.
Fixed the prompt to not include non-printable characters as it was hosing up the prompt when you ran "command regex foo" and entered multi-line editing mode.

Fixed error strings to include more complete descriptions when bad regular expressions are entered.

Removed the old IOHandlerLinesUpdated function as it is no longer needed (inheriting from IOHandlerDelegateMultiline takes care of what this function used to do).

Kate Stone e30f11d9ee Complete rewrite of interactive editing support for single- and multi-line input.
Improvements include:
* Use of libedit's wide character support, which is imperfect but a distinct improvement over ASCII-only
* Fallback for ASCII editing path
* Support for a "faint" prompt clearly distinguished from input
* Breaking lines and insert new lines in the middle of a batch by simply pressing return
* Joining lines with forward and backward character deletion
* Detection of paste to suppress automatic formatting and statement completion tests
* Correctly reformatting when lines grow or shrink to occupy different numbers of rows
* Saving multi-line history, and correctly preserving the "tip" of history during editing
* Displaying visible ^C and ^D indications when interrupting input or sending EOF
* Fledgling VI support for multi-line editing
* General correctness and reliability improvements

Jim Ingham 26c7bf9312 Rework the way we pass "run multiple command" options to the various API's that
do that (RunCommandInterpreter, HandleCommands, HandleCommandsFromFile) to gather
the options into an options class.  Also expose that to the SB API's.

Change the way the "-o" options to the lldb driver are processed so:
1) They are run synchronously - didn't really make any sense to run the asynchronously.
2) The stop on error
3) "quit" in one of the -o commands will not quit lldb - not the command interpreter
that was running the -o commands.

I added an entry to the run options to stop-on-crash, but I haven't implemented that yet.

Enrico Granata 06be059ad9 Allow Python commands to optionally take an SBExecutionContext argument in case they need to handle 'where they want to act' separately from the notion of 'currently-selected entity' that is associated to the debugger. Do this in an (hopefully) non-breaking way by running an argcount check before passing in the new argument. Update the test case to also check for this new feature. www update to follow

Enrico Granata 735152e3b0 Add a --help (-h) option to "command script add" that enables users to define a one-liner short help for their command
Also, in case they don't define any, change the default from "Run Python function <blah>" into "For more information run help <blah>"

The core issue here is that Python only allows one docstring per function, so we can't really attach both a short and a long help to the same command easily
There are alternatives but this is not a pressing enough concern to go through the motions quite yet

Zachary Turner de963e9a09 Adds the notion of an OptionValidator.
The purpose of the OptionValidator is to determine, based on some
arbitrary set of conditions, whether or not a command option is
valid for a given debugger state.  An example of this might be
to selectively disable or enable certain command options that
don't apply to a particular platform.

This patch contains no functional change, and does not actually
make use of an OptionValidator for any purpose yet.  A follow-up
patch will begin to add the logic and users of OptionValidator.
