- .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:
