a shell would interpret it. A few examples that we now handle correctly
INPUT: "Hello "world
OUTPUT: "Hello World"
INPUT: "Hello "' World'
OUTPUT: "Hello World"
INPUT: Hello" World"
OUTPUT: "Hello World"
This broke the setting of dictionary values for the "settings set" command
for things like:
(lldb) settings set target.process.env-vars ["MY_ENV_VAR"]=YES
since we would drop the quotes. I fixed the user settings controller to use
a regular expression so it can accept any of the following inputs for
dictionary setting:
settings set target.process.env-vars ["MY_ENV_VAR"]=YES
settings set target.process.env-vars [MY_ENV_VAR]=YES
settings set target.process.env-vars MY_ENV_VAR=YES
We might want to eventually drop the first two syntaxes, but I won't make
that decision right now.
This allows more natural setting of the envirorment variables:
settings set target.process.env-vars MY_ENV_VAR=YES ABC=DEF CWD=/tmp

- Added new utility function to Arg, GetQuotedCommandString, which re-assembles
the args into a string, replacing quotes that were originally there.
- Modified user settings stuff to always show individual elements when printing out
arrays and dictionaries.
- Added more extensive help to 'settings set', explaining more about dictionaries
and arrays (including current dictionary syntax).
- Fixed bug in user settings where quotes were being stripped and lost, so that
sometimes array or dictionary elements that ought to have been a single element
were being split up.

if passed in a NULL new_value and the operation intended is eVarSetOperationAssign.
This fixed a bug where in TestSettings.py:
# Set the run-args and the env-vars.
self.runCmd('settings set target.process.run-args A B C')
self.runCmd('settings set target.process.env-vars ["MY_ENV_VAR"]=YES')
# And add hooks to restore the settings during tearDown().
self.addTearDownHook(
lambda: self.runCmd("settings set -r target.process.run-args"))
self.addTearDownHook(
lambda: self.runCmd("settings set -r target.process.env-vars"))
"settings set -r target.process.env-vars" was not restoring the original env-vars
setting.

the parent of Process settings; add 'default-arch' as a
class-wide setting for Target. Replace lldb::GetDefaultArchitecture
with Target::GetDefaultArchitecture & Target::SetDefaultArchitecture.
Add 'use-external-editor' as user setting to Debugger class & update
code appropriately.
Add Error parameter to methods that get user settings, for easier
reporting of bad requests.
Fix various other minor related bugs.
Fix test cases to work with new changes.

replacing the "(lldb)" prompt, the "frame #1..." displays when doing
stack backtracing and the "thread #1....". This will allow you to see
exactly the information that you want to see where you want to see it.
This currently isn't hookup up to the prompts yet, but it will be soon.
So what is the format of the prompts? Prompts can contain variables that
have access to the current program state. Variables are text that appears
in between a prefix of "${" and ends with a "}". Some of the interesting
variables include:
// The frame index (0, 1, 2, 3...)
${frame.index}
// common frame registers with generic names
${frame.pc}
${frame.sp}
${frame.fp}
${frame.ra}
${frame.flags}
// Access to any frame registers by name where REGNAME is any register name:
${frame.reg.REGNAME}
// The current compile unit file where the frame is located
${file.basename}
${file.fullpath}
// Function information
${function.name}
${function.pc-offset}
// Process info
${process.file.basename}
${process.file.fullpath}
${process.id}
${process.name}
// Thread info
${thread.id}
${thread.index}
${thread.name}
${thread.queue}
${thread.stop-reason}
// Target information
${target.arch}
// The current module for the current frame (the shared library or executable
// that contains the current frame PC value):
${module.file.basename}
${module.file.fullpath}
// Access to the line entry for where the current frame is when your thread
// is stopped:
${line.file.basename}
${line.file.fullpath}
${line.number}
${line.start-addr}
${line.end-addr}
Many times the information that you might have in your prompt might not be
available and you won't want it to print out if it isn't valid. To take care
of this you can enclose everything that must resolve into a scope. A scope
is starts with '{' and ends with '}'. For example in order to only display
the current file and line number when the information is available the format
would be:
"{ at {$line.file.basename}:${line.number}}"
Broken down this is:
start the scope: "{"
format whose content will only be displayed if all information is available:
"at {$line.file.basename}:${line.number}"
end the scope: "}"
We currently can represent the infomration we see when stopped at a frame:
frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19
with the following format:
"frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n"
This breaks down to always print:
"frame #${frame.index}: ${frame.pc} "
only print the module followed by a tick if we have a valid module:
"{${module.file.basename}`}"
print the function name with optional offset:
"{${function.name}{${function.pc-offset}}"
print the line info if it is available:
"{ at ${line.file.basename}:${line.number}}"
then finish off with a newline:
"\n"
Notice you can also put newlines ("\n") and tabs and everything else you
are used to putting in a format string when desensitized with the \ character.
Cleaned up some of the user settings controller subclasses. All of them
do not have any global settings variables and were all implementing stubs
for the get/set global settings variable. Now there is a default version
in UserSettingsController that will do nothing.

handles user settable internal variables (the equivalent of set/show
variables in gdb). In addition to the basic infrastructure (most of
which is defined in UserSettingsController.{h,cpp}, there are examples
of two classes that have been set up to contain user settable
variables (the Debugger and Process classes). The 'settings' command
has been modified to be a command-subcommand structure, and the 'set',
'show' and 'append' commands have been moved into this sub-commabnd
structure. The old StateVariable class has been completely replaced
by this, and the state variable dictionary has been removed from the
Command Interpreter. Places that formerly accessed the state variable
mechanism have been modified to access the variables in this new
structure instead (checking the term-width; getting/checking the
prompt; etc.)
Variables are attached to classes; there are two basic "flavors" of
variables that can be set: "global" variables (static/class-wide), and
"instance" variables (one per instance of the class). The whole thing
has been set up so that any global or instance variable can be set at
any time (e.g. on start up, in your .lldbinit file), whether or not
any instances actually exist (there's a whole pending and default
values mechanism to help deal with that).
