This commit adds a new GUI widget type, called CodeDocument, which
is a TextDocument that can additionaly store data related to the
debugger.
This fixes various bugs and crashes that occured when we switched
between files in debug mode, because we previously held stale breakpoint
data for the previous file in the Editor object.
We now keep this data at the "document" level rather than the Editor
level, which fixes things.
We can now step into library code in the debugger.
Since we now need the whole source code of our libraries
(and not just the headers), we clone the whole serenity git repo into
/usr/share/serenity.
Previously, we did source-level singlestepping by inserting a
breakpoint at every source line and continued execution until we hit
a breakpoint. We did this because we used to not generate source
locations debug info for library code, and it allowed us to not single
step through lots of library code to get to the next source line
(which is super slow).
Since we now do generate source locations debug info for libraries
(-g1), we can improve the way we implement source level stepping by
stepping at the assembly level until we reach a different source code
location.
This patch adds GUI::FocusEvent which has a GUI::FocusSource.
The focus source is one of three things:
- Programmatic
- Mouse
- Keyboard
This allows receivers of focus events to implement different behaviors
depending on how they receive/lose focus.
This also resolves some typing issues that only 'accidentally' worked, like declaring
a function to return type A, and the definition actually returning type B (which works
if type B is a subtype of type A). I like to call these "ninja imports".
To prevent problems like this in the future, I put all globals in a HackStudio.h.
I'm not sure about the name, but main.h and common.h felt wrong.
Since the vast majority of message boxes should be modal, require
the parent window to be passed in, which can be nullptr for the
rare case that they don't. By it being the first argument, the
default arguments also don't need to be explicitly stated in most
cases, and it encourages passing in a parent window handle.
Fix up several message boxes that should have been modal.
Adds a new, more restrictive read-only state to TextEditor which
forbids copying, selecting, editor cursors, and context menus.
Provides a unique appearance on focus which accomodates ComboBox
widgets. All TextEditor modes are now accessed by enum and
set_mode() which sets the editor to Editable, ReadOnly or
DisplayOnly. Updates applications still using set_readonly().
Get rid of the weird old signature:
- int StringType::to_int(bool& ok) const
And replace it with sensible new signature:
- Optional<int> StringType::to_int() const
This patch adds a context menu to variables in the debugger variable
tree view that has an option to set the value of a variable. An input
box will pop up asking for the new value of the variable, which
is then parsed and used to set the actual variable.
HackStudio uses a TreeView to display the list of current variables
while debugging, and when the program completes, it sets that view's
model to a null model. This would trip an assertion if the TreeView
had something selected at the time, so this patch lessens the
assertion into a simple null check.
Additionally, the cursor would look laggy when moving about the
editor because the code was waiting for a window repaint to update
the cursor's look when it makes more sense to update the cursor
when it actually moves. This change also requires the base
GUI::TextEditor to expose a getter to tell if its currently in a drag
selection.
Finally, requesting a context menu in the line ruler on the side of
the editor would also place/remove breakpoints, which was counter
intuitive, so this requires a left click to modify breakpoint placement.
.. and make travis run it.
I renamed check-license-headers.sh to check-style.sh and expanded it so
that it now also checks for the presence of "#pragma once" in .h files.
It also checks the presence of a (single) blank line above and below the
"#pragma once" line.
I also added "#pragma once" to all the files that need it: even the ones
we are not check.
I also added/removed blank lines in order to make the script not fail.
I also ran clang-format on the files I modified.
This patch adds the ability to enable "input history" on a textbox,
allowing to navigate between the history with the arrow keys.
Also removes a custom TextBox subclass from HackStudio that added
the exact same hooks, and moves it to use the now standard ones.
And move canonicalized_path() to a static method on LexicalPath.
This is to make it clear that FileSystemPath/canonicalized_path() only
perform *lexical* canonicalization.
