The scrollbar, mini map and the segment delimiters were also using the
incorrect bytes per row value when changing data size forced a change in
the number of bytes per row. From the definition of the new value it
follows that bytesPerRow/bytesPercell == m_bytesPerRow/bytesPerCell, so
it is not necessary to switch it when it is divided by that quantity.
The error was that if `m_bytesPerRow` was not divisible by the number of
bytes per column then ImHex would crash but wouldn't crash if it was.
When `m_bytesPerRow` is not equal to the resultant bytes per row
obtained by the product of column count and bytes per column, then the
later bytes per row were be allocated but the former bytes per row were
being written causing heap corruption and crashes.
Instead of resetting `m_bytePerRow` when it can't be used, a new
variable (`bytesPerRow`) is created with the correct value and used in
the rest of the function. This way if the user goes back to choose a
data size that divides the old `m_bytesPerRow` then the number would
still be available and not overwritten. Test indicate that this approach
works and previous crashes are eliminated while producing the desired
output.
Added clion-like bracket matching feature with shortcut to go to the
other one. Also improved some cumbersome repeated function call.
Added support for using negative indices in coordinates so -1 is the last
line or column, -2 the previous, etc..
Pattern library has fixes for column errors being incorrectly set for lines
containing tabs that are not replaced by 4 spaces.
Fix a typo in `screenshot_descriptions.json` reported in #2330. While I
was presented with the contributing doc, I came across another typo
that's fixed in the second commit.
allows the ability to assign colors to global placed and non-placed
variables, pattern, local and calculated pointer variables, template
arguments, function variables and arguments, etc etc etc. It
accomplishes this using the parser and the token sequence generated by
the lexer. It still uses the original colorizing code but the underlying
data holding the pattern has been updated to be easier to use and to
debug. The changes are too numerous to cite here.It is a big but
necessary step to bring the pattern editor to a somewhat useful state.
There may be one commit in the pattern language repo needed to be able
to run this code
This pr updates the pattern language library to include two fixes.
The first fix deal with local variables that are children of a
structure, a union, a bitfield or an array losing their offsets when the
parent's `setOffset()` is called.
The second fix is that local variables of unions were being used as size
contributors of the patterns place with said unions.
Further details may be found in the pattern language pull requests for
the files listed as changed in the PL submodule in this pr.
