+### Miscellaneous

-### Strings, Character Sets and Translations
+#### Debug Messages

-#### Pulling Updated Translations
+We have an override for `wxLogDebug()` to make it work even in non-debug builds
+of wx and on windows, even in mintty.

-Once in a while it is necessary to pull new and updated translations from
-transifex.
-
-For this you need the transifex client, available for Windows as well from
-chocolatey as `transifex-client`.
-
-To pull translations run:
-
-```bash
-tx pull -af
-```
-
-then check `git status` and if any message catalogs were updated, commit the
-result as:
-
-```bash
-git commit -a --signoff -S -m'Transifex pull.'
-git push
-```
-
-#### Translations Message Catalog
-
-Strings that need to be translated by our wonderful translators on transifex
-(thank you guys very much) need to be enclosed in `_("...")`, for example:
+It works like `printf()`, e.g.:

 ```cpp
-wxLogError(_("error: something very wrong"));
+int foo = 42;
+wxLogDebug(wxT("the value of foo = %d"), foo);
 ```

-The next time you run cmake after adding a string to be translated, the `.pot`
-message catalog source will be regenerated, and you will see a loud message
-telling you to push to transifex.
-
-Strings in the XRC XML GUI definition files are automatically added to the
-message catalog as well.
-
-If you are working on a branch or a PR, don't push to transifex until it has
-been merged to master.
-
-Once it is, push it with:
-
-```bash
-tx push -s
-```
-
-#### Interaction with non-wxWidgets Code
-
-Use our `UTF8(...)` function to force any `wxString` to UTF-8 for use by other
-libraries, screen output or OS APIs. For example:
+From the core etc. the usual:

 ```cpp
-fprintf(STDERR, "Error: %s\n", UTF8(err_msg));
+fprintf(stderr, "...", ...);
 ```
+, will work fine.

-There is one exception to this, when using `wxString::Printf()` and such, you
-can't pass another `wxString` to the `%s` format directly, use something like
-this:
-
-```cpp
-wxString err;
-err.Printf("Cannot read file: %s", fname.wc_str());
-```
-
-this uses the `wchar_t` UTF-16 representation on Windows and does nothing
-elsewhere.
-
-For calling Windows APIs with strings, use the wide char `W` variants and the
-`wc_str()` method as well.

+You need a debug build for this to work or to even have a console on Windows.
+Pass `-DCMAKE_BUILD_TYPE=Debug` to cmake.

 ### Release Process

-#### Environment
+#### GnuPG Key

-The variable `VBAM_NO_PAUSE`, if set, will cause cmake to not pause before gpg
-signing operations, you want to set this if you've disabled your gpg passphrase
-to not require interaction during release builds.
+You will need to create a GnuPG key for signing your commits and release tags,
+and upload it to a keyserver.

-gpg set up with your key is helpful for the release process on all environments
-where a binary is built, but you can also make the detached signature files
-yourself at the end of the process.
+Make sure to install GnuPG on all environments where you will be making commits
+and tags.

-For codesigning windows binaries, put your certificate into
-`~/.codesign/windows_comodo.pkcs12`.
+#### Certificates

-On Mac the 'Developer ID Application' certificate stored in your login keychain
-is used, `keychain unlock` will prompt you for your login keychain password, to
-avoid that set the `LOGIN_KEYCHAIN_PASSWORD` environment variable to your
-password.
+Make sure you have set up a Windows code signing certificate with the right
+password and a Mac 'Developer ID Application' certificate.
+
+Put the Windows certificate into `~/.codesign/windows_comodo.pkcs12` as a PKCS12
+file that is password protected, and put the password for it into

-For this the optimal environment is a linux distribution with the mingw
-toolchain, I use fedora.
+The 32-bit build is a legacy build for Windows XP compatibility. You will need
+the MinGW toolchain to build it. The easiest method is to use the MINGW32 MSYS2
+environment.

-You can set up a shell on a fedora distribution with docker as described here:
+Make sure the Visual Studio `signtool.exe` is in your path, you can start MSYS2
+with an inherited `PATH` from a Visual Studio enabled environment or add it to
+your shell configuration.

-not install the base toolchain (mingw gcc, binutils, winpthreads) using the

-
-https://mxe.cc/
+First install dependencies with:

 ```bash
-sh tools/win/linux-cross-builder -32
+./installdeps
 ```
-
-You can also use msys2 on Windows, this is not recommended:
+. Then build the 32-bit binary as follows:

 ```bash
-sh tools/win/msys2-builder -32

+#### ARM64 Windows Binary

-#### 64-bit Mac Binary
+You will need the MSVC ARM64 cross toolchain to build this binary, if you used
+the install script from [here](https://github.com/rkitover/windows-dev-guide)
+you will have it installed, otherwise run Visual Studio Installer and install
+the component.
+
+To enter the ARM64 cross environment, edit the PowerShell profile described
+[here](https://github.com/rkitover/windows-dev-guide) or use the `vcvarsall.bat`
+script with the `amd64_arm64` argument as described
+[here](https://learn.microsoft.com/en-us/cpp/build/building-on-the-command-line?view=msvc-170).

-to install):
-
-```bash

+generate once you join their developer program from XCode. This is the
+certificate of the type 'Developer ID Application' stored in your login
+keychain.
+
+If you are not using a GUI session, you will need to use a method to unlock your
+login keychain before building so that your codesigning certificate can be used.
+Adding the certificate and key to the System keychain is also a method that some
+people use.
+
+To unlock your keychain on login, you can add something like this to your
+`~/.zshrc`:

 ```bash
-/usr/local/bin/bash tools/osx/builder -64
+security unlock-keychain -p "$(cat ~/.login-keychain-password)" login.keychain
 ```
+, with your login password in that file.
+
+For notarization to work, you will need to create an app-specific password on
+https://appleid.apple.com , get your Team ID from your Apple Developer account,
+and store them with this command:
+
+```bash
+xcrun notarytool store-credentials AC_PASSWORD \
+               --apple-id you@domain.com \
+               --team-id <DeveloperTeamID> \
+               --password <secret_app_specific_2FA_password>
+```
+. Once all of this is set up, run:
+
+```bash
+tools/osx/builder
+```
+, this will take a while because it builds all of the dependencies.

-# This script locates the SFML library
-# ------------------------------------
-#
-# Usage
-# -----
-#
-# When you try to locate the SFML libraries, you must specify which modules you want to use (system, window, graphics, network, audio, main).
-# If none is given, the SFML_LIBRARIES variable will be empty and you'll end up linking to nothing.
-# example:
-#   find_package(SFML COMPONENTS graphics window system) # find the graphics, window and system modules
-#
-# You can enforce a specific version, either MAJOR.MINOR or only MAJOR.
-# If nothing is specified, the version won't be checked (i.e. any version will be accepted).
-# example:
-#   find_package(SFML COMPONENTS ...)     # no specific version required
-#   find_package(SFML 2 COMPONENTS ...)   # any 2.x version
-#   find_package(SFML 2.4 COMPONENTS ...) # version 2.4 or greater
-#
-# By default, the dynamic libraries of SFML will be found. To find the static ones instead,
-# you must set the SFML_STATIC_LIBRARIES variable to TRUE before calling find_package(SFML ...).
-# Since you have to link yourself all the SFML dependencies when you link it statically, the following
-# additional variables are defined: SFML_XXX_DEPENDENCIES and SFML_DEPENDENCIES (see their detailed
-# description below).
-# In case of static linking, the SFML_STATIC macro will also be defined by this script.
-# example:
-#   set(SFML_STATIC_LIBRARIES TRUE)
-#   find_package(SFML 2 COMPONENTS network system)
-#
-# On Mac OS X if SFML_STATIC_LIBRARIES is not set to TRUE then by default CMake will search for frameworks unless
-# CMAKE_FIND_FRAMEWORK is set to "NEVER" for example. Please refer to CMake documentation for more details.
-# Moreover, keep in mind that SFML frameworks are only available as release libraries unlike dylibs which
-# are available for both release and debug modes.
-#
-# If SFML is not installed in a standard path, you can use the SFML_ROOT CMake (or environment) variable
-# to tell CMake where SFML is.
-#
-# Output
-# ------
-#
-# This script defines the following variables:
-# - For each specified module XXX (system, window, graphics, network, audio, main):
-#   - SFML_XXX_LIBRARY_DEBUG:   the name of the debug library of the xxx module (set to SFML_XXX_LIBRARY_RELEASE is no debug version is found)
-#   - SFML_XXX_LIBRARY_RELEASE: the name of the release library of the xxx module (set to SFML_XXX_LIBRARY_DEBUG is no release version is found)
-#   - SFML_XXX_LIBRARY:         the name of the library to link to for the xxx module (includes both debug and optimized names if necessary)
-#   - SFML_XXX_FOUND:           true if either the debug or release library of the xxx module is found
-#   - SFML_XXX_DEPENDENCIES:    the list of libraries the module depends on, in case of static linking
-# - SFML_LIBRARIES:    the list of all libraries corresponding to the required modules
-# - SFML_FOUND:        true if all the required modules are found
-# - SFML_INCLUDE_DIR:  the path where SFML headers are located (the directory containing the SFML/Config.hpp file)
-# - SFML_DEPENDENCIES: the list of libraries SFML depends on, in case of static linking
-#
-# example:
-#   find_package(SFML 2 COMPONENTS system window graphics audio REQUIRED)
-#   include_directories(${SFML_INCLUDE_DIR})
