5756105347 fix: Text highlighter crash (#2595)
The assumption that the number of lines of colors will be equal to the
number of lines in the input signal is incorrect. As issue #2594 shows,
erroneous input can cause the lexer to end processing the input file
prematurely thus being unable to create tokens past the line where the
error occurred which in turn implies that no colors can be found beyond
those lines.

To fix the crash (the underlying problem is user caused and can't be
fixed) is to use the size of the vectors containing the first token
index of each line since that size must be equal to the number of lines
stored in token sequence.

Fixes #2594

64cbd5fc8d Make the syntax highlighter more thread safety aware (#2585)
By creating copies of the required inputs on the main thread just before
the task is spawned. A;so if task is still running when new data can be
copied then the task is interrupted thus avoiding concurrency without
mutexes. Atomics are used to signal state information used to determine
what and when to spawn.

Also includes update to pattern editor library and some fixes to syntax
highlighting error when custom types defined inside namespaces were used
inside the namespaces without the full qualified name and other small
changes mostly to improve the current style.

bfa9788099 impr: Various fixes and improvements to the pattern editor (#2559)
- fixed crash when utf8 chars were present in text editor
- fixed unable to scroll when cursor at line 1
- removed dependencies on thext editor that were not being used.

I had to go back to the old code (old for me) and fit in the changes
that were applied to the new code.That was only possible by
incorporating some of the new structural differences to the text editor.
This created new bugs and crashes that I ve have fixed but there may be
ones that I couldn't find in the very small amount of time I could spend
testing so that this commit wouldn't be delayed. If more crashes are
found due to the mixing of old and new code they should be resolved when
the new code is brought in.

67efea6444 Fix segfault when opening recent file with pattern sync; Don't show p… (#2448)
…attern selection popup when pattern is already open

This PR does two things. Most importantly, it fixes a segfault that can
be caused by opening a recent file with pattern sync enabled.
Secondly, it makes it so that the pattern selection popup does not
appear if you already have text in the pattern editor for a given
provider (due to CLI args, a project file, pattern sync, etc.). If you
open a file normally, that text field is empty and the popup will appear
so you can select a pre-made pattern like usual.

df1e97af0a improv: further reformatting of text editor in an effort to bring it into the ui plugin. (#2385)
Added the ui namespace and broke the main rendering function into a set
of smaller functions. Reorganized the header code separating functions
into rough groups that eventually will be in separate files.

d429424f67 improv: refactor text editor to follow imhex style. (#2382)
Also fixes two bugs:
1) error messages not staying visible
2) uncaught exception when struct name is duplicated.

A lot of the code using coordinates for start and end has been moved to
use Selections instead. Created more string manipulation code that uses
utf8 indices aka Coordinates directly. This makes implementing editing
functions easier by not having to go back and forth from string indices
to char indices and back. Currently, the substring, erase and []
operator support coordinates and str indices.

b3deeb29b3 fix: typing t< on pattern editor spams the log infinitely (#2379)
The error was caused when the search for the closing delimiter extended
past the last token in the sequence, which happened because the initial
increments before the loop starts were not being accounted for in the
loop ending condition. This was fixed by decrementing the limit of
possible steps to account for the initial steps taken.

8f3d07ea69 fix: imported patterns used for inheritance were not highlighted. (#2356)
The problem was that imported files didn't have token sequences to
obtain the UDT variables. The fix was to create maps from the file name
to the token sequence and then process each imported file to obtain all
the variables needed. Function variables are skipped since they can be
part of the code.
There are also some minor code style corrections and a fix in the text
editor where the last line of a selection was not being deleted.

e18d583a00 feat: Added experimental external editor support. (#2347)
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.

5df8ec78aa improv: removing tabs (#2345)
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.

e7a2729d36 feat: semantic syntax highlights for pattern editor. (#2214)
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
