This commit adds a few basic variable substitution operations:
- length
Find the length of a string or a list
- length_across
Find the lengths of things inside a list
- remove_{suffix,prefix}
Remove a suffix or a prefix from all the passed values
- regex_replace
Replace all matches of a given regex with a given template
- split
Split the given string with the given delimiter (or to its
code points if the delimiter is empty)
- concat_lists
concatenates any given lists into one
Closes#4316 (the ancient version of this same feature)
Non-interactive shells (i.e. when running scripts) do not need this
functionality, so they are a boatload of wasted time.
This significantly reduces the script startup and shutdown times when
there are lots of executables in PATH or lots of entries in the history.
It is possible to set the run.sh mode via the SERENITY_RUN environment
variable, but the SERENITY_DISK_IMAGE="grub_disk_image" override for
qgrub mode was only checking $1. This makes qgrub mode work via 'ninja
run' without explicitly setting SERENITY_DISK_IMAGE:
SERENITY_RUN=qgrub ninja run
Instead of declaring a reserved area from byte 0x160 to 0x400, we
change the declaration of TimerStructure array to be 32 units.
Also, a static_assert was added, to ensure that the calculation is
right.
This reverts commit af22204488.
According to the HPET specification, each theoretical comparator takes
32 bytes in the MMIO space.
Although I hardly believe that any system will implement all 32
comparators, in practice if a machine happens to have more than 3
comparators, we need to address the comparators correctly if we want to
use them.
This fixes some precision issues in Painter::draw_triangle()
that caused the Cube demo to leave pixels empty between triangles
under certain angles.
Also adds some extra comments for clarity and early returns when
parts of the triangle do not need to be drawn.
It was previously using draw_tiled_bitmap, which always aligns the
tiles with the global origin and does not respect the alpha of the
source. Switch to a new Painter::blit_tiled helper which uses
Painter::blit under the hood, which has more correct behavior.
We now restart the language server transparently if it crashes.
If the language server crashes too frequently (current threshold is
twice within 3 seconds), we give up and will not attempt to restart it
again. HackStudio will still work fine, but features that depend on the
language server will not function.
To support this change we use a new class, 'ServerConnectionWrapper',
that holds the actual ServerConnection and is responsible for restarting
the language-server if it crashes.
Closes#5574.
- FileDB::get() now returns nullptr if the file is not in the FileDB
- Added FileDB::get_or_create_from_filesystem()
- Added FileDB::add() version that receives that file's content as a
parameter
This fixes an issue were "Find in Files" would not use the up-to-date
content of a file with unsaved changes.
The issue existed because 'FindInFilesWidget' uses
Project::for_each_text_file, which retrieves files by their absolute
path. However, when a file is opened in an Editor, it is created with
a relative path.
This caused us to store two ProjectFile objects that refer to the same
file - one with a relative path and one with an absolute path.
HackStudio keeps a map that stores the different ServerConnection
instances we have open.
Previously, that map was indexed by a project's root path.
This did not make much sense because we only support opening a single
project with each instance of the HackStudio program.
We now index the different ServerConnections by the language name, which
allows us to support talking to multiple language-servers in the same
project (e.g C++ and Shell).
This also fixes an issue where if you first opened a Shell file, and
then a C++ file in the same project, then C++ language-server features
would not work.
This class is used in the AHCI code to handle a big request of
read/write to the disk. If we happen to encounter such request,
we will get the needed amount of physical pages from the
already-allocated physical pages in AHCIPort, and with that we
will create a ScatterList that will create a Region that maps
all of these pages in a contiguous virtual memory range.
Then, we could easily copy to/from this range, before and after
calling the operation on the StorageDevice as needed with
read or write operations.
The hierarchy is AHCIController, AHCIPortHandler, AHCIPort and
SATADiskDevice. Each AHCIController has at least one AHCIPortHandler.
An AHCIPortHandler is an interrupt handler that takes care of
enumeration of handled AHCI ports when an interrupt occurs. Each
AHCIPort takes care of one SATADiskDevice, and later on we can add
support for Port multiplier.
When we implement support of Message signalled interrupts, we can spawn
many AHCIPortHandlers, and allow each one of them to be responsible for
a set of AHCIPorts.
We use atomic_signal_fence and atomic_thread_fence together to prevent
reordering of memory accesses by the CPU and the compiler.
The usage of these functions was suggested by @tomuta so we can be sure
that important memory accesses happen in the expected order :)
