If we exhaust the buffer stream, the reads appear to succeed, but the stream
itself panics when we later attempt to drop it. To prevent it, we check for
errors explicitly.
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.
You can now mark String message parameters with the [UTF8] attribute.
This will cause the generated decoder to perform UTF-8 validation and
reject the message if the given parameter is not a valid UTF-8 string.
This frees up the receiving side from having to do this validation at
a higher level.
Now most classes dictate how they are serialized and deserialized when
transmitted across LibIPC sockets. This also makes the IPC compiler
a bit simpler. :^)
We're starting with a very basic decoding API and only ISO-8859-1 and
UTF-8 decoding (and UTF-8 decoding is really a no-op since String is
expected to be UTF-8.)
The HackStudio debugger integrates with LibDebug to provide
source-level debugging.
The user can set breakpoints at various positions in the source code,
and then run the program in debug mode.
When the program is stopped, the current execution position is
displayed, and the user can insert/remove breakpoints, continue
execution, or single step the program.
This patch adds GUI::Action::create_checkable() helpers that work just
like the existing create() helpers, but the actions become checkable(!)
Clients are no longer required to manage the checked state of their
actions manually, but instead they will be checked/unchecked as needed
by GUI::Action itself before the activation hook is fired.
