These are supposed to be both functions and macros. I'm not sure
how to provide the functions at the same time as the macros,
as they collide with each other and cause compile errors.
However, some ports fully expect them to be functions.
For example, OpenSSH stores them into structures as function
pointers.
This patchset makes it possible for the shell to format the current
buffer of the line editor live, with somewhat accurate cursor tracking.
Since this feature is pretty goofy at best, let's keep it off by default
for now :^)
In /proc/PID/fds we get not only file name, but also additional information
about file type, state etc. This commit makes `lsof' command separate these
components. When you are filtering files by file name, only actual file name
is checked (not additional data).
I put this into the <AK/PrintfImplementation.h> header in the hope that
it could be re-used by the printf implementation. That would not be
super trivial though, so I am not doing that now.
Previously, when resolving the paths for the FormEditor widget icons
we didn't take into the account that calling class_name() returns the
widget name with a "GUI::" prefix.
Also, we now skip over widgets that we don't have an icon for.
The `consume_quoted_string()` can now take an escape character. This allows it
(for example) to capture a string's enclosing quotes. The escape character is
optional by default.
You can also consume and unescape a quoted string with the eponymous method
`consume_and_unescape_string()`. It takes an escape character as parameter
(backslash by default). It builds a String in which common escape sequences
get... unescaped :^) (e.g. \n, \r, \t...).
We already have installation instructions for ubuntu but not yet for
Debian. Gcc-9 is not available on Debian stable so instructions for
switching to and from Debian testing are added.
Gcc 8.3.0 (which is the current version in debian 10 stable) seems to
fail at building AK. New people might get stuck when they try to run
make inside the ./Build folder and fail at building serenity.
The thread joining logic hadn't been updated to account for the subtle
differences introduced by software context switching. This fixes several
race conditions related to thread destruction and joining, as well as
finalization which did not properly account for detached state and the
fact that threads can be joined after termination as long as they're not
detached.
Fixes#3596
Instead of just implementing format specifiers ad-hog this commit
implements the exact syntax std::format uses.
There are still a ton of features that are not supported by this
implementation, however, the format specifiers should be parsed
correctly.
In some cases however, the format specifiers aren't quite parsed
correctly, for example:
String::formatted("{:{}}", 42, 4)
should produce the string " 42" however an (unrelated) assertion fails.
This is because vformat doesn't consider nested parentheses. I have to
spend some time coming up with a simple way of doing this, I don't feel
like doing that right now.
The fundamental code for this already exists, by limiting the number of
format arguments (arbitrarily) to 256 large widths are used to encode
that these should be taken from other format parameters.
