MSYS2/Cygwin/MinGW/Clang support installs statistics

MSYS2/Cygwin/MinGW/Clang support extension for Visual Studio Code

This extension brings in configuration and usage of the MSYS2, Cygwin, MinGW and Clang toolchains to the Visual Studio Code and its OSS builds like VSCodium.

Technically the extension provides a set of commands for use with the ${command:...} substitution feature used throughout the VS Code and its extensions to enhance their configurability. These commands return full paths to the respective toolchain-specific executables such as the CMake itself, generators, compilers etc.

Features

• CMakeTools integration

  • 32/64-bit MSYS2/Cygwin/MinGW/Clang toolchain configurations

• CppTools integration

  • Cross-language debugging with GDB

  • Code navigation with IntelliSense

• Isolated operation where no global PATH modification is neccessary

• Support for MSVCRT-based and UCRT-based MinGW toolchains provided by MSYS2

Setup & Configuration

This extension is primarily designed to work with the CMakeTools extension although it is possible to make use of it with any build system which utilizes the command substitution capability.

The following steps are to be performed in order to configure a minimal usable MSYS2, Cygwin, MinGW/Clang and Visual Studio Code environments.

Hint the VS Code canonic Ctrl+Shift+P command palette shortcut extensively used below has a very convenient F1 alias.

Per user Visual Studio Code extensions

The following extensions are to be installed

ms-vscode.cmake-tools ms-vscode.cpptools fougas.msys2

by opening the Visual Studio Code extensions panel with the Ctrl+Shift+X keyboard shortcut and pasting the above line into the entry, then installing each of highlighted extensions individually.

Next come optional yet recommended extensions which enhance the usage experience

twxs.cmake krvajalm.linter-gfortran

which provide the CMake and Fortran file syntax highlighting, respectively.

Per user VSCodium extensions

Unfortunately there are not all extensions available from alternative OpenVSX extension repository used by OSS builds of Visual Studio Code such as VSCoduim. This specifically means no out-of-the-box launch/debugging support. The avaliable extensions are installed as follows:

The following extensions are to be installed

ms-vscode.cmake-tools twxs.cmake fougas.msys2

by opening the Visual Studio Code extensions panel with the Ctrl+Shift+X keyboard shortcut and pasting the above line into the entry, then installing each of highlighted extensions individually.

Per user Visual Studio Code configuration

Currently the MSYS2 extension provides no means of auto-detecting the supported toolchain locations.

Instead, it is configured manually via the per user configuration settings specified in the settings.json configuration file. These settings can be set either via the UI or by direct editing the settings.json file in the form of raw JSON data. In either case, the settings are accessible via the Ctrl+, keyboard shortcut.

MSYS2 configuration

The (64-bit only) MSYS2 location is specified by the msys2.root configuration setting in the settings.json file which is set to c:\msys64 by default as it is the default location proposed by the MSYS2 installer. This specifically means that no manual configuration is required when MSYS2 is installed into default location.

Cygwin configuration

The 32/64-bit Cygwin locations are specified by the cygwin32.root and cygwin64.root configuration settings in the settings.json file which are set to c:\cygwin and c:\cygwin64 by default, respectively, as they are the default locations proposed by the Cygwin installers. This specifically means that no manual configuration is required when Cygwins are installed into default locations

MinGW configuration

The 32/64-bit MinGW locations are specified by the respective mingw32.root and mingw64.root configuration settings. If not set, their values will be computed according to the msys2.root value, hence there is no need to coupe with them in order to use the MSYS2-provided MinGW installations.

Note that in order to use the Cygwin-provided MinGW toolchains the mingw??.root configuration settings are to be set manually.

MinGW selection

The MSYS2 extension offers selection of the source the MinGW toolchain comes from.

There are three implemented MinGW providers:

• MSYS2

• Cygwin

• Standalone MinGW

The MinGW selection logics works as follows. If the mingw??.root configuration setting is set, it is used to determine the root path to the standalone MinGW installation such as MinGW-W64 or TDM-GCC. Otherwise, the mingw??.provider configuration setting is used to determine the MinGW provider. There are four possible values for it: msys2, cygwin32, cygwin64 and anything else with msys2 taken as the default. If it is set to anything but the first three, the selector falls back to the above mingw??.root case. 32/64-bit MinGW installations are determined separately with the respective configuration settings.
