GUI overview
|
|
============
|
|
|
|
Examples of the various Seer views and dialogs.
|
|
|
|
Main View
|
|
---------
|
|
|
|
The main view for Seer looks like this:
|
|
|
|
|
|
* Source/Function/Types/Variables/Libraries
|
|
* The list of source/header files that were used in the program.
|
|
* Search for Functions, Types, and Static Variables.
|
|
Dobule clicking will open the source file.
|
|
* The list of shared libraries referenced by the program.
|
|
* The list of source/header files can be searched. This will "shrink" the list of files shown.
|
|
* Double clicking on a file will open it in the Code Manager.
|
|
|
|
* Variable/Register Info
|
|
* Show variable and register values.
|
|
* "Logger" - log the value of a variable. Manually enter it or double click on the variable in the file
|
|
that is opened in the code manager.
|
|
* "Tracker" - create a list of variables to show the value for whenever gdb reaches a stopping point
|
|
(step, next, finish, etc.). When the stopping point is reached, all variables in the list will show
|
|
their potentially new value.
|
|
* "Registers" - show the values of all cpu registers.
|
|
|
|
* Code Manager.
|
|
* The large area of the middle part of the Seer gui.
|
|
* Source files are opened in this view.
|
|
* Text in a file can be seached for with ^F.
|
|
* Variables can be added to the "Logger" by double clicking the variable name.
|
|
Double click with CTLR key pressed will prepend variable with "*".
|
|
Double click with SHIFT key pressed will prepend variable with "&".
|
|
Double click with CTRL+SHIFT key pressed will prepend variable with "*&".
|
|
* Variables can be added to the "Tracker" by selecting the variable name and RMB and select
|
|
"Add variable to Tracker".
|
|
* Variables can be added to the "Memory Visualizer" by selecting the variable name and RMB and select
|
|
"Add variable to Memory Visualizer".
|
|
* A breakpoint/printpoint can be created by RMB on a specific line.
|
|
* Can execute to a specific line by RMB on a specific line.
|
|
* Tabs in this view can be detached by double-clicking a tab.
|
|
|
|
* Breakpoints, Watchpoints, Catchpoints, Printpoints, manual gdb commands, and logs.
|
|
* The area below the Code Manager.
|
|
* Manual commands. Manually enter a gdb or gdbmi command.
|
|
The commands are remembered for the next Seer use.
|
|
* Breakpoint manager. Create and manage breakpoints.
|
|
* Watchpoint manager. Create and manage watchpoints.
|
|
A watchpoint monitors when a variable is accessed (read, write, read/write).
|
|
* Catchpoint manager. Create and manage catchpoints.
|
|
A catchpoint stops execution on a C++ throw/rethrow/catch call.
|
|
* Printpoint manager. Create and manage printpoints.
|
|
A printpoint is like a breakpoint but it allows you to print variables at
|
|
that printpoint. See gdb's 'dprintf' call.
|
|
* GDB output. A log of any output from the gdb program itself.
|
|
* Seer output. A log of any output from the Seer program itself. As diagnostics.
|
|
* Tabs in this view can be detached by double-clicking a tab.
|
|
|
|
* Stack frame information.
|
|
* Stack frame list. A frame can be double clicked to change the scope (the current function).
|
|
* Stack frame arguments. For each frame, print the arguments passed to each function.
|
|
* Stack locals. For the current function, print the values of the local variables.
|
|
|
|
* Thread information.
|
|
* Thread ids. A list of all threads. Double click on a thread id to change the scope (the current thread).
|
|
* Thread frames. For each thread, list its stack frames.
|
|
|
|
* Supports Gdb's Reverse Debugging mode.
|
|
* Turn instruction recording on or off.
|
|
* Set playback direction to forward or reverse.
|
|
|
|
Open Dialog
|
|
-----------
|
|
|
|
When the open executable dialog is invoked, it looks like this:
|
|
|
|
|
|
Seer Console
|
|
------------
|
|
|
|
All text output from the executable will go to the Seer console. Text input for the executable can be entered via the console too.
|
|
|
|
|
|
|
|
Assembly View
|
|
-------------
|
|
|
|
Normally Seer will just show the source code as tabs in the Code Manager. The program's assembly can also be show as a tab.
|
|
|
|
Select "View->Assembly View" and an extra tab will be shown alongside the source code tabs that shows the current assembly being executed. Here is an example.
|
|
|
|
|
|
Like the source code tabs, breakpoints can be set in the assembly tab. The current instruction is highlighted.
|
|
|
|
Double-clicking on entries in the "Breakpoints" tab and the "Stack frames" tab will show the assembly for those addresses.
|
|
|
|
There are "Nexti" and "Stepi" hot-keys, as defined by your config settings. Normally "Ctrl+F5" and "CTRL+F6".
|
|
Using "^F" in the assembly tab will show a powerful search bar.
|
|
|
|
**The assembly feature in Seer is new. Feel free to suggest changes/features.**
|
|
|
|
|
|
Memory Visualizer
|
|
-----------------
|
|
|
|
When looking at the contents of raw memory in the Memory Visualizer, it looks like this :
|
|
|
|
Memory | Disassembly
|
|
--- | ---
|
|
 | 
|
|
|
|
Array Visualizer
|
|
-----------------
|
|
|
|
When looking at the contents of arrays in the Array Visualizer, it looks like this :
|
|
|
|
Normal | Spline | Scatter
|
|
--- | --- | ---
|
|
 |  | 
|
|
|
|
Two arrays can be used as an X-Y plot. For example, this simple 'points' array forms the X-Y outline of a shape.
|
|
```
|
|
int main() {
|
|
int points[] = {50,1,20,91,97,35,2,35,79,91,50,1};
|
|
return 0;
|
|
}
|
|
```
|
|
|
|
X values | Y values | XY Values
|
|
--- | --- | ---
|
|
 |  | 
|
|
|
|
Struct Visualizer
|
|
-----------------
|
|
|
|
When looking at the contents of a C/C++ struct or a C++ class in the Struct Visualizer, it looks like this.
|
|
This example shows the contents of "*this" for the current C++ class that Seer is in. All structure members
|
|
that are basic types can be edited.
|
|
|
|
|
|
|
|
There is also a **Basic Struct Visualizer** that is more light weight, but can not follow pointers and can not
|
|
be edited.
|
|
|
|
Image Visualizer
|
|
-----------------
|
|
|
|
When looking at the contents of raw memory that is an image, the Image Visualizer can be used.
|
|
|
|

Starting Seer
|
|
=============
|
|
|
|
Seer is meant to easily start the program to debug from the command line. gdb has multiple
|
|
methods for debugging a program. So Seer naturally does too.
|
|
|
|
Go to the Wiki to see all the ways to run Seer.

|
Building Seer
|
|
=============
|
|
|
|
Go to the Wiki to see how to build Seer. Seer can be built with Qt6. As well, for the time being, it can still be built with Qt5.
