How to list more lines of code code in LLDB - lldb

Question

How do I get LLDB to list more lines of code in the current frame. By default it only does 7. This is the best I can do so far:
(lldb) f
frame #9: 0x000000010001fce0 DualIssueInstructionSchedulerTest`void std::__1::random_shuffle<std::__1::__wrap_iter<exchange::ExchangeMessage*>, ExchangeWithLotsOfMessages::test_method()::$_5&>(__first=__wrap_iter<exchange::ExchangeMessage *> # 0x00007ffeefbf5298, __last=__wrap_iter<exchange::ExchangeMessage *> # 0x00007ffeefbf5290, __rand=0x00007ffeefbf56e0)::$_5&&&) at algorithm:3203
3200 for (--__last; __first < __last; ++__first, --__d)
3201 {
3202 difference_type __i = __rand(__d);
-> 3203 swap(*__first, *(__first + __i));
3204 }
3205 }
3206 }
(lldb) l 3100
3100 result_type max() const {return b();}
3101
3102 friend bool operator==(const uniform_int_distribution& __x,
3103 const uniform_int_distribution& __y)
3104 {return __x.__p_ == __y.__p_;}
3105 friend bool operator!=(const uniform_int_distribution& __x,
3106 const uniform_int_distribution& __y)
3107 {return !(__x == __y);}
3108 };
3109
(lldb) l
3110 template<class _IntType>
3111 template<class _URNG>
3112 typename uniform_int_distribution<_IntType>::result_type
3113 uniform_int_distribution<_IntType>::operator()(_URNG& __g, const param_type& __p)
3114 {
3115 typedef typename conditional<sizeof(result_type) <= sizeof(uint32_t),
3116 uint32_t, uint64_t>::type _UIntType;
3117 const _UIntType _Rp = __p.b() - __p.a() + _UIntType(1);
3118 if (_Rp == 1)
3119 return __p.a();
(lldb) l
3120 const size_t _Dt = numeric_limits<_UIntType>::digits;
3121 typedef __independent_bits_engine<_URNG, _UIntType> _Eng;
3122 if (_Rp == 0)
3123 return static_cast<result_type>(_Eng(__g, _Dt)());
3124 size_t __w = _Dt - __clz(_Rp) - 1;
3125 if ((_Rp & (std::numeric_limits<_UIntType>::max() >> (_Dt - __w))) != 0)
3126 ++__w;
3127 _Eng __e(__g, __w);
3128 _UIntType __u;
3129 do
(lldb) l
3130 {
3131 __u = __e();
3132 } while (__u >= _Rp);
3133 return static_cast<result_type>(__u + __p.a());
3134 }
3135
3136 #if _LIBCPP_STD_VER <= 14 || defined(_LIBCPP_ENABLE_CXX17_REMOVED_RANDOM_SHUFFLE) \
3137 || defined(_LIBCPP_BUILDING_LIBRARY)
3138 class _LIBCPP_TYPE_VIS __rs_default;
3139
Is there a way to increase the context for f or lass a range of lines to l?

Answer 1

If you just want to widen the window for one source listing, do:
(lldb) source list -c 40 -l 3100
then just hitting return (to auto-repeat the command) will continue with this count.
There are also two lldb settings that control the default for how much source gets printed:
(lldb) help settings set
...
stop-line-count-after -- The number of sources lines to display that come after the current source line when displaying a stopped context.
stop-line-count-before -- The number of sources lines to display that come before the current source line when displaying a stopped context.
The "current source line" is the pc if you are looking at the stop listing and the source line you passed to "list" if you are using that command.
Repeated calls to "l" (or just pressing to auto-repeat) will just print the sum of the two number of lines. So you would put:
settings set stop-line-count-before 10
settings set stop-line-count-after 10
or whatever number you like in your ~/.lldbinit to change this behavior.
