+ .DESCRIPTION
+ Helper script to format all header and source files in the repository.
+ By default, the script will recursively search under the repo root for
+ files to format. Users can give explicit parameters indicating how the
+ search should include and exclude filetypes.
+ If users don't want the search functionality, they can instead provide
+ an explicit list of files to format.
+ .PARAMETER RepoRoot
+ Full path to the root of the repository which is the target of the search.
+ Will default to the root of the current working directory.
+ .PARAMETER Include
+ Array of filetype extensions to target for formatting.
+ By default, targets standard extensions for header and source files.
+ Follows the same rules as the -Include parameter for Get-ChildItem.
+ .PARAMETER Exclude
+ Array of filetype extensions to exclude from formatting.
+ By default, excludes generated XAML files.
+ Follows the same rules as the -Exclude paramter for Get-ChildItem.
+ .PARAMETER Files
+ Array of files to format. The script will exit if one of the provided
+ filepaths does not exist.
+ .EXAMPLE
+ .\clang-format-all.ps1
+ Formats all header and source files under the repository root.
+ .EXAMPLE
+ .\clang-format-all.ps1 -RepoRoot 'S:\repos\calculator' -Include '*.h', '*.cpp' -Exclude '*.g.*'
+ Formats all *.h and *.cpp files under 'S:\repos\calculator', excluding files with an extension
+ like *.g.*
+ .EXAMPLE
+ .\clang-format-all.ps1 -File 'S:\repos\calculator\src\CalcViewModel\UnitConverterViewModel.h', 'S:\repos\calculator\src\CalcViewModel\MemoryItemViewModel.cpp'
+ Formats the specified files.

+/**
+ zpl - Pushing the boundaries of simplicity.
+
+Usage:
+# define ZPL_IMPLEMENTATION exactly in ONE source file right BEFORE including the library, like:
+
+# define ZPL_IMPLEMENTATION
+# include "zpl.h"
+
+ You can also use a lightweight version of zpl by using ZPL_NANO, like:
+
+# define ZPL_IMPLEMENTATION
+# define ZPL_NANO
+# include "zpl.h"
+
+ There is also a distribution that provides only the essential modules, you can enable it by defining ZPL_PICO.
+ Currently, the distro offers: preprocessor helpers, debug module, memory API (except vm) and collections.
+ Some of these modules used to depend on zpl_printf, but they use the standard library if the distro is enabled now.
+
+# define ZPL_IMPLEMENTATION
+# define ZPL_PICO
+# include "zpl.h"
+
+Options:
+ ZPL_EXPOSE_TYPES - exposes all zpl defined types to the global namespace. This means type such as `zpl_u32` is now available as `u32` globally.
+ ZPL_DEFINE_NULL_MACRO - to let zpl define what NULL stands for in case it is undefined.
+ ZPL_NO_MATH_H - disables the use of math.h library and replaces it with custom routines or SIMD.
+ ZPL_HEAP_ANALYSIS - enables heap allocator analysis tools
+ ZPL_PARSER_DISABLE_ANALYSIS - disables the extra parsing logic that would collect more information about node's formatting and structure.
+ this is useful in scenarios where a raw parsing performance is preferred over a more complex analysis.
+ It is not recommended to serialise data back since we lack the extra information about the original source document.
+
+GitHub:
+ https://github.com/zpl-c/zpl
