bedrock-pc/src, branch v0.4.1Bedrock emulator and assembler for Windows and Linux
https://code.benbridle.com/bedrock-pc/atom?h=v0.4.12024-08-13T05:06:07ZImprove performance of hierarchical file navigation2024-08-13T05:06:07ZBen Bridlebridle.benjamin@gmail.com2024-08-13T05:06:07Zurn:sha1:05326e69658bfcb0e857988bc3ddfa9b2655ec52
The most recently closed directory listing is cached instead of being
discarded. The next time a directory is to be opened, if the file path
is the same as the cached directory, the cached directory listing is
used in order to save the entire listing from having to be regenerated.
This is expected to result in performance gains on Windows.
Prevent unused variable warning on Linux2024-08-11T00:38:13ZBen Bridlebridle.benjamin@gmail.com2024-08-11T00:38:13Zurn:sha1:68f633f6ba35a4fbbae9ed22fc759ce3544f6a0e
The base variable is only used when compiling on Windows, so an
unused variable warning is raised when compiling on Linux.
Fix panic in ReadOnlyTextBuffer2024-08-10T02:37:02ZBen Bridlebridle.benjamin@gmail.com2024-08-10T02:34:00Zurn:sha1:59820850b2bd326a20306279bdcbe52982a74889
Previously when reading from a ReadOnlyTextBuffer the pointer would
fall off the end and crash the emulator.
This commit also makes the ReadOnlyTextBuffer Unicode-compatible,
rather than the previous behaviour of clamping every character into
the ASCII range.
Fix ascend-to-parent behaviour of file device2024-08-10T02:37:02ZBen Bridlebridle.benjamin@gmail.com2024-08-10T02:36:42Zurn:sha1:516f5cf5edfb7a2c4a4f3571aa6ce692a476d582
We were finding the parent of the relative path and then passing this
to the BedrockFilePath::from_path constructor, but this constructor
expects to be passed an absolute path and so was unconditionally
returning None.
Refactor the file device2024-08-07T05:09:14ZBen Bridleben@derelict.engineering2024-08-07T05:09:14Zurn:sha1:38d40a2c5d4b553f524d87755b8e2e0e47928b8a
This is the Windows side of the refactoring job. The windows crate has
been added as a dependency in order to get a list of available drives
by drive letter, and a virtual top-level root directory has been
implemented in the Windows code to make it possible for programs to
hierarchically navigate between available drives.
Refactor the file device2024-08-06T07:12:43ZBen Bridlebridle.benjamin@gmail.com2024-08-06T07:11:46Zurn:sha1:65b53003e8de9543ba25a3b3d3cace399b92dc1d
The major feature of this refactor is the creation of BedrockFilePath,
a type which can be losslessly converted into an operating-system
specific path or a Bedrock-style byte path. It also prevents file paths
which can't be represented as Bedrock-style byte paths from being
constructed, and allows the use of a base directory which acts as an
inescapable sandbox.
BedrockFilePath will support the creation of a virtual root directory
on Windows which will allow navigation between drive letters via the
standard hierarchical navigation ports.
This commit has been tested on Linux, but not yet Windows. Further work
is expected before the new code will work on Windows.
Increase frame time to 8ms2024-08-05T01:42:53ZBen Bridlebridle.benjamin@gmail.com2024-08-05T01:42:53Zurn:sha1:406b4d3ea56a19c0389b4214a7d8d15bf3028eb8
This is slightly more efficient on the CPU, while not making any
visible difference to the user.
Update cursor callback to latest version of Phosphor2024-08-04T04:44:51ZBen Bridlebridle.benjamin@gmail.com2024-08-04T04:44:51Zurn:sha1:f07c3d277406b4338bbe6a3371d58da0da33905f
The most recent Phosphor commit c141d8f unified the is_cursor_visible
and cursor_icon callbacks.
Set error flag when file device cannot ascend to parent directory2024-08-04T01:09:48ZBen Bridlebridle.benjamin@gmail.com2024-08-04T01:09:48Zurn:sha1:67d5d2c434db7d6b85d438f263ca51c26715a583
This should have been happening previously, but was missed.
Fix compilation on Linux2024-08-04T01:09:04ZBen Bridlebridle.benjamin@gmail.com2024-08-04T01:09:04Zurn:sha1:b82ffe72b3f72b8fc5e42464319bab69973c097f
Some Windows-only library functions were added in during a previous
commit while I was developing on Windows.
