| - | ==== Admin access === | + | === Msys2 path mangling === |
| + | |||
| + | Since Windows expects paths like ''c:/Users/Sato/'' and Unix expects paths like ''/home/Sato'' the Msys2 shell does path mangling so that windows programs will find what is expected. | ||
| + | |||
| + | For example, one types: | ||
| + | |||
| + | ./prg.exe / /c/Users/Sato/Music/ | ||
| + | |||
| + | and the passed arguments (''argv'' in C parlance) are: | ||
| + | |||
| + | C:\msys64\home\Sato\prg.exe | ||
| + | C:/msys64/ | ||
| + | C:/Users/Sato/Music/ | ||
| + | |||
| + | Normally this is fine, but seldom it breaks programs. To disable it one needs to setup an environment variable: ''MSYS2_ARG_CONV_EXCL'' ([[https://github.com/msys2/msys2/wiki/Porting#filesystem-namespaces|Documentation]]). | ||
| + | |||
| + | == Docker == | ||
| + | |||
| + | A common example is docker for windows. One probably wants an alias in their ''~/.bashrc''. | ||
| + | |||
| + | alias docker='MSYS2_ARG_CONV_EXCL="*" docker' | ||
| + | |||
| + | So that Msys2 won't mangle any path. | ||
| + | |||
| + | === TTY-sensible programs === | ||
| + | |||
| + | Few programs, like __nodejs__, have problems using Msys2. When you execute them the console seems to hang. It is caused because the expect stdout do be a TTY, in other words stdout must follow the terminal interface protocol. | ||
| + | |||
| + | In Mysys2 shell, it is not the case: | ||
| + | |||
| + | $ node -p -e 'Boolean(process.stdout.isTTY)' | ||
| + | false | ||
| + | |||
| + | Fortunately there is a solution: the program **winpty** | ||
| + | |||
| + | $ winpty node -p -e "Boolean(process.stdout.isTTY)" | ||
| + | true | ||
| + | |||
| + | Let us see in action: | ||
| + | |||
| + | $ node | ||
| + | |||
| + | Nothing happens, until you press CTRL-C stopping it. | ||
| + | |||
| + | $ winpty node | ||
| + | Welcome to Node.js v13.11.0. | ||
| + | Type ".help" for more information. | ||
| + | > | ||
| + | |||
| + | Much better! **winpty** can be installed with pacman. | ||
