Users can now synchronize the content of the pattern editor with a file
on disk when exporting a pattern. Any modifications made in the pattern
editor are automatically saved to the file and when the pattern editor
gains focus it will automatically load any changes to the file on disk.
This feature is brand new and can have unforeseen problems so test it
fully before risking losing work.
Added major changes to how the text editor handles utf8 characters with
the added ability to obtain them using the [] operator and column
coordinates as indices. Sanitize coordinates was renamed to Set
Coordinates and can be used instead of the constructor to guarantee no
out of range asserts and/or exceptions. Improved move left and right
readability and cursor accuracy when clicking. Fixed single character
selection by double-clicking it. Deleted old and unused code and other
changes that I can't remember about atm.
These changes are part of an effort aimed at removing tabs from ImHex
that started some time ago. Here text preprocessing is removed from all
the places were it was done before and moved to the places where files
are read that go in the pattern editor with two notable exceptions.
1) Pattern import reads patterns in order to present a list that can be
filtered.That can safely ignore preprocessing since only needs to get
information needed to filter.
2) The pattern editor can incorporate text from the clipboard so that
needs to be preprocessed as well.
find/replace is unable to add tabs or carriage returns so this should
cover all angles.
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.
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
### Problem description
While working with the section view, I noticed the window wasn't
resizable.
### Implementation description
This simply removes the `ImGuiWindowFlags_NoResize` flag, and then when
drawing the section window sets the hex editor to 70% of the available
window, leaving 30% to the pattern data. This is not ideal, but I think
before a full rewrite of the section window system this would probably
be a simple change to make it a lot more usable.

A while back there were some changes to the pattern language library
that changed the way shared_pointers are created using
shared_from_this(). Unfortunatelly the changes were not complete and
various bugs were created among them 2234, json type not working, unable
to export files, static arrays of bitfields,... The cause of the errors
was that in class Pattern the member m_parent was left as a raw pointer
and it needs to be handled by shared pointers. Also there were some
cases in which share pointers were needed but unique pointers were used
instead. Both cause crashes when shared_from_this is used on pointers
that are not managed by shared_ptr. Another source of errors were
infinite loops of clone and reference that caused stack overflow. The
fixes include making m_parent a weak pointer, turning unique pointers
into shared pointers and moving codefrom the copy constructors into
clone to break the infinite loops.These changes are the bare minimum
needed to bring the pattern language back to the full functionality that
it had before shared_from_this was introduced or at least thats the
hope.
This pr aims at fixing for negative values in advanced search for
numerical values. For a simple example try searching for -1 for int32_t
which is 0xFFFFFFFF. With the changes you can now find -1 for 1,2,4 or 8
byte integers.
Internal types are bigger than or equal to the types selected in the
options. Search keys are converted to the bigger type, but the values
read from the input file are not. This works ok for positive numbers,
but for negatives it needs some casting.
The casting is performed inside a newly added function that takes the
value returned by read, the size in bytes of the selected type in the
options and a template argument for the 64 bit type the value is stored
into.
I have tested positive and negative values for several different sizes
of signed integers. Also tested unsigned integers both in the low range
(near lowest limit) and in the high range (near largest possible value
for that type)
