So, this is for PDB debugger (one for Visual C++ compiler only) and it is limited, hardcoded and otherwise ugly implementation, plus there is some work left to do (support more types, support structured browsing), but in general I think it is already useful feature:

index.php?t=getfile&id=5943&private=0

"recognized high-level types" are now supported in expressions:

index.php?t=getfile&id=5948&private=0

How can I activate it?
I have compiled current Git version with MSC 2017 64 bit, but it seems to be working in the old way.

Should work out of box-> something is wrong.

Core should be trunk version for Value recogniction.

Project must be compiled with MSC.

Not all U++ types are supported. Check ide/debuggers/Pretty.cpp for the list of types currently supported:

		pretty.Add("Upp::Date", { 0, THISFN(PrettyDate) });
		pretty.Add("Upp::Time", { 0, THISFN(PrettyTime) });
		pretty.Add("Upp::ValueArray", { 0, THISFN(PrettyValueArray) });
		pretty.Add("Upp::ValueMap", { 0, THISFN(PrettyValueMap) });
		pretty.Add("Upp::Value", { 0, THISFN(PrettyValue) });
		pretty.Add("Upp::String", { 0, THISFN(PrettyString) });
		pretty.Add("Upp::WString", { 0, THISFN(PrettyWString) });
		pretty.Add("Upp::Vector", { 1, THISFN(PrettyVector) });
		pretty.Add("Upp::BiVector", { 1, THISFN(PrettyBiVector) });
		pretty.Add("Upp::Array", { 1, THISFN(PrettyArray) });
		pretty.Add("Upp::BiArray", { 1, THISFN(PrettyBiArray) });
		pretty.Add("Upp::Index", { 1, THISFN(PrettyIndex) });
		pretty.Add("Upp::VectorMap", { 2, THISFN(PrettyVectorMap) });
		pretty.Add("Upp::ArrayMap", { 2, THISFN(PrettyArrayMap) });

		pretty.Add("std::vector", { 1, THISFN(PrettyStdVector) });
		pretty.Add("std::basic_string", { 1, THISFN(PrettyStdString) });


If none of those helps, we will have to dig into it... E.g. for starters, testcase would help.

Is debugged code 32 or 64?

It was my fault. Works perfectly.
It's very easy to debug this way. Thank you!

Tree view now can be used to see any element:

index.php?t=getfile&id=5949&private=0

Thank you Mirek. Debugger is very improved.
How do you access to tree view?

Best regards

Very smart! Laughing

Let me show to the Forum the full picture.
The trick was to insist some times on moving the right vertical bar to the left.

index.php?t=getfile&id=5950&private=0

Could not resist:

Really useful.

Could you add a copy to clipboard option to get the variable text?

Hello koldo,

Some time ago I implemented feature for GDB that copy the text to the clipboard from the tree. Optimally, we should have the same functionality for PDB with the shared code to reduced code maintenance. I also planned to add window that will open when you want to examine full string value inside TheIDE. This functionallity should also be shared between debuggers. This is optimal implementation to not favor any of debugger. Especially that PDB is not available on Linux.

I think above improvements are great, but they are not present with the GDB back-end. Mirek, do you think we can port this functionality without much effort (by extracting common code?)?

Sincerely,
Klugier

U++ - one framework to rule them all.

Unfortunately not. That is one of reasons I have resisted these features for so long.

GDB and PDB are completely different beasts. GDB is just issuing text commands to gdb binary via text pipe and interpreting results.

PDB code is really a full featured debugger. It is using Win32 debugging API directly and symbol server to really understand the layout of objects, directly reads debugee memory etc... That are actually requirements to make this kind of functionality possible.

This definitely possible to binaries produced by GCC toolchain too. But it is a LOT of work, probably would involve thorough study of GDB sources and about a year to complete.

IMHO, it is easier to use LLDB, which is available as a lib.

"The LLDB debugger APIs are exposed as a C++ object oriented interface in a shared library. The lldb command line tool links to, and uses this public API."

Cool! It runs, thank you Mirek.

The last features you are adding to debugger are really useful, and they have helped me to detect errors.

Best regards
