lldb - how to print an object without summary?

Question

Problem: I've created a summary for my object, let's think a trivial boost::intrusive_ptr (I have more complex, so this is just for example )

now if I have:

boost::intrusive_ptr< MyClass > pobj;

and I type from the console

p pobj

I'll see summary for MyClass.

But what if I want to see it's internal px member - that is pobj.px ?

I know two ways:

• put summary into a category, then temporary disable it (inconvenient)
• frame variable -Y0 and this second would be ideal, but what to do if I want to see a result of an expression ? that is something like p MyObj.GetContents.GetSmartPtr()

I've tried already something like:

frame variable -Y0 0ドル

but this doesn't work.

I use XCode 4.6.3.

Is there a way to turn off summary ? Probably someone knows if this was cured in XCode 5 or latest lldb ?

Answer 1

You can see the raw information by using frame variable -R.

(lldb) fr v test
(std::__1::string) test = "hi there"
(lldb) fr v -R test
(std::__1::string) test = {
 __r_ = {
 std::__1::__libcpp_compressed_pair_imp<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> >::__rep, std::__1::allocator<char> > = {
 __first_ = {
 = {
[...]

update: OP clarifies that he's at a value in a convenience variable, e.g. std::string foo () { return std::string("hi there"); }

(lldb) p foo()
(std::string) 0ドル = "hi there"

and wants to view 0ドル without any formatting -- and frame variable doesn't have access to the convenience variables so this needs to go through the expression (aka p) command. In this case, the only workaround I know is to temporarily disable the format e.g. type category disable libcxx which is what this person is hoping to avoid doing.

• dev_null: this doesn't help against expressions. that is if there is no 'test' but std::string is just returned as a result of a function.
• Enrico Granata: The Top-of-Tree open source LLDB has a -R (—raw-output) flag

Answer 2

Instead of p ... do dwim-print -R -- ....

help p reveals that p is an alias for dwim-print --, and then help dwim-print reveals the option -R, which stands for "raw output".

Also, as the other answer says, if you were using fr v ("print all local variables", aka frame variable), that has the same flag: fr -v -R.
