### Problem description
<!-- Describe the bug that you fixed/feature request that you
implemented, or link to an existing issue describing it -->
Fixed possible bug of `EventManager::unsubscribe`
`std::map` only allows unique key, but the same token can subscribe to
multiple events.
1a2a926b77/lib/libimhex/include/hex/api/event.hpp (L104-L107)
If the previous token has already subscribed to an event, then when
subscribing again, `getTokenStore().insert` will not do anything
(Because its type is `std::map`)
1a2a926b77/lib/libimhex/include/hex/api/event.hpp (L122-L134)
At this point in `unsubscribe`, the `iter` may not be able to find the
correct event and erase it
### Implementation description
<!-- Explain what you did to correct the problem -->
Change `tokenStore` to `std::multimap` instead of `std::map`, which
cannot unsubscribe multiple events correctly
### Screenshots
<!-- If your change is visual, take a screenshot showing it. Ideally,
make before/after sceenshots -->

I noticed the bad score on code factor so I reorganized it to make it
more readable and maintainable. In order to break down the big function
into it much smaller parts I encapsulated all the variables that the
functions need to access in two classes, one for the imgui related
statics and the other for non-static variables.
When writing the smaller functions I was noticed that there was room to
simplify the existing algorithms by writing functions that could be
called by parts that previously shared no code. I tested the changes the
same way I tested the original and it seems to work the same way but
maybe a bit faster. Although it may be possible to further optimize the
present code code factor no longer flags the function at all.
As discussed (many times) on Discord, does the same as the new favorite
tag, but instead allows you to add multiple groups.
Initially, this would cause some insane issues with draw/reset
(apparantly) fighting eachother in the pattern drawer. After a lot of
trial and error, I decided to rewrite the flow that is responsible for
calling reset. Now evaluating patterns is the one to decide when the
reset happens, not the core "game"-loop.
To make sure that draw and reset can never happen at the same time, the
mutex originally used for the favorites has been repurposed. Due to the
restructuring, the mutex in the favorite-task is no longer needed, as
that will only ever kick-off after reset is called and if there are
actually patterns, which can never line up to be accessed on different
threads at the same time.
Last but not least, I noticed that hard crashes could result in your
config file getting overridden. I added a check to prevent that.
Last I issue I can see is that if you use an excessive amount of
favorites/groups, a crash can still happen, but it only happens when you
close the program (occasionally, but unpredictable). Before, this would
happen if you ran the evaluation a second time. I boiled the cause of
the crash down to these lines of code in evaluator.cpp >
patternDestroyed:
```cpp
if (pattern->isPatternLocal()) {
if (auto it = this->m_patternLocalStorage.find(pattern->getHeapAddress()); it != this->m_patternLocalStorage.end()) {
auto &[key, data] = *it;
data.referenceCount--;
if (data.referenceCount == 0)
this->m_patternLocalStorage.erase(it);
} else if (!this->m_evaluated) {
err::E0001.throwError(fmt::format("Double free of variable named '{}'.", pattern->getVariableName()));
}
}
```
Specifically, trying to access the `*it` is the reason for the crash
(this was also the cause of the crashes before my fixes, but then during
evaluation).
I'm suspecting the root cause is somewhere in the `.clone` methods of
the patterns. I'd say that for now a crash when closing the program is
more acceptable than during evaluation (which can even happen if you use
favorites).
This PR fix libmagic dumping files in the imhex cwd when compiling them
This code was actually written by you (notice the source branch), this
PR is just a reminder that the fix works and you can merge it ^^

This PR intends to add support for .NET scripts that can extend ImHex's
functionality in a portable and cross-platform way.

This PR it just a hack to fix#1160 , it doesn't solve the underlying
problem.
It fixes the problem because by using execvp() directly, it avoids the
call to `sh` done with `system()`, which has a bug on Ubuntu 22.04 which
makes it i,compatibles with the glibc inside the AppImage.
It doesn't fix the underlying problem because the programs we call
themselves still link to the AppImage's libraries instead of the system
ones.
### Problem description
Currently, the providers use the method `isSavable()` to determine both
if they can use "Save" or "Save as".
This behaviour is problematic because some providers may need to be
saveable but not saveable as: for example the view provider. The
original provider may not allow to be saved.
### Implementation description
I separate these two behaviour by creating another function:
`isDumpable()`, that return true by default but can be overridden by the
provider to return false, if the provider should not be dumped in any
way.
### Additional things
While I was at it, I also marked "export" operations as needing the
"dumpable" flag. That way, we can't accidentally export the whole
address space of a process as base64.
I also added documentation for these some functions in Provider
This PR fixes some things about crash handling:
- when the terminate handler is called, immediately set it back to the
original one, so can't make a recursion if the crash-handling code fails
- Only save projects if the crash occured after Imhex finished startup
- do not update the project location when saving the crash backup file:
this will remove problems when `EventAbnormalTermination` is called
before `crashCallback()`
I also added a bit more documentation
In order to do this I add to make some other additions :
- Add a warning popup (TODO, maybe add some icons to differentiate
error/warning popups in a future PR ?)
- create showError() and showWarning() functions, as helpers to show a
message both to the logs and as a popup
This PR updates imgui and its dependencies from the last time, ~1 year
ago

Commits will be refactored before merging
Things you might ask :
- why did you remove `ImGui_ImplGlfw_SetBorderlessWindowMode()` ?
-> Where is it used ? The only usage of it I see is commented
(cb9a3b1f55/lib/external/imgui/source/imgui_impl_glfw.cpp (L757))
- why did you remove the implot anti aliasing flag ?
-> They.. seem to have removed it altogether ?
https://github.com/epezent/implot/issues/479
This PR does two things :
- save opened projects as recent entries
- refactor stuff about recent entries in a separate file. The reason is
that I felt like welcome_screen.cpp was really big ( 685 lines before
this, 500 now). What do you think ?

- Add a new file 'crash.json' to store metadata about the crash, like
the log file or project opened
- show the log file of the session that caused the crash to the user
- Correctly restore the project path
Compiler when compiling doesn't use them in those cases and emit a
warning, which is turned into an error by `-Werror`. Unfortunately,
CPack doesn't expose the logic it uses for stripping binaries.
I just realized one feature request existed about this tool and have
added a comment to it referring this pr. Errors and additions are
described in the fork commit already. I'm not sure if I should repeat
them here again. I have tested the changes thoroughly, but it is always
possible some fringe case was not tested and is incorrect. The tests
were done using the many similar online calculators for IEEE 754
floating point formats.
IEEE 745 floating point tool redesign modeled after 'float toy' web app
(http://evanw.github.io/float-toy/)
Streamlined output using colors and compact layout which can be further
simplified.
Chosen display mode (detailed or simplified) is automatically saved and
set on new sessions.
Edit the binary bits, the integer hexadecimal or the floating point
decimal values and the entire app will update with the change.
Supports the main IEEE745 standard formats (half, single and double
precision) together with custom formats of size <= 64 bits.
Each format choice uses and displays the number of significant decimal
digits defined by the mantissa size.
Added labels to identify the location of each bit box inside the binary
representation.
Satisfies round trip / idempotent (reproducing) conversion property
Added theme colors, radio buttons for display mode and a clear button
that resets the tool.
Removed previously and incorrectly added locale translation to various
labels and languages
Attempted to adhere to code style formatting using existing code as
example.
An effort was made to use preferred variable types and functions from
std namespace when appropriate.
Attempted to document code using comments.
Not implemented / left to complete at an later time
Arbitrary width and precision formats.
Extended precision formats.
Shortest string property.
hexadecimal floating point display and conversions.
This PR adds some documentation. It's actually pretty random, I followed
the function calls I was curious about and commented whenever I wasn't
sure/I thought it needed clarification
You might want to make sure to squash them, because the commits are kind
of a mess, I didn't went through the effort of interactive rebase
Currently there is no way to save the pattern code progamically from a
plugin unless the builtin plugin is modified to add those events. This
pull request will be adding ability to load and save pattern code from
specified file.
This PR handles errors that NFD might encounter (both in Init() and the
other method to open the dialog), and log them in the logs and in the
GUI
This (among other) fix the crash I had running ImHex as root and opening
a file
This pull request changes Config Directories on Linux to only include
the XDG_CONFIG_HOME directory, as opposed to all directories in
XDG_DATA_DIRS before (introduced in
https://github.com/WerWolv/ImHex/pull/644/files#diff-c1a4d2b63fed168a9a3568944e9cadeae096f2ddcec3649e4a9b2d29fd104be0L162-L166).
Reasons:
- This changes the location of the config file to the standard directory
meant for configurations
- This prevents the config file from being read/written in system
locations, like /usr/share
This PR also includes a migration task that will run on Linux and move
config/GUI dimensions to the new directory
as a bonus, as discussed on discord, it writes the logs to a Data
directory instead of a Config directory
PR title is self explaining
I may modify other providers implementations to display a detailed error
message later
I'm not sure how to deal with other locales because the format changed.
Before, I had to add and comment the key in all locale files, now I'm
not so sure.
Issue: https://github.com/WerWolv/ImHex/issues/522
Implementation of chunk based entropy analysis in diagram.hpp available
