Treat msys2 bash shell as Linux by default

[comiluv]

With msys2 installed on Windows 11, ran from Msys2 bash shell, tealdeer thinks the platform is Windows, but the platform should be treated as linux.
For example, Get-Childitem doesn't work on msys2 bash but tealdeer shows tldr-page entry for Get-Childitem Powershell cmdlet.
On the otherhand, pacman is the package manager for msys2 but tealdeer doesn't show its tldr-page entry on tldr pacman

$ Get-Childitem
bash: Get-Childitem: command not found
$ tldr Get-Childitem

  List items in a directory.
  Note: This command can only be used through PowerShell.
  More information: <https://learn.microsoft.com/powershell/module/microsoft.powershell.management/get-childitem>.

  List all non-hidden items in the current directory:

      Get-ChildItem

  List only directories in the current directory:

      Get-ChildItem -Directory

  List only files in the current directory:

      Get-ChildItem -File

  List items in the current directory, including hidden items:

      Get-ChildItem -Hidden

  List items in a directory other than the current one:

      Get-ChildItem -Path path\to\directory

$ pacman
error: no operation specified (use -h for help)
$ tldr pacman

Edit: also applicable to Git Bash on Windows o/s

The way it currently works is that we look at the --platform argument and as a fallback the platform that tealdeer was compiled to. Hence, tldr --platform linux pacman shows the expected page (it checks linux, then windows) and tldr pacman does not (it only checks windows).

I think that having windows as the default platform in Git Bash is still correct. I suppose that you don't want to always type -p linux. We don't have an option for "platform" in our configuration file right now, but it seems like a good idea to add one. Until then, I suppose you can create a shell alias so that tldr expands to tldr -p linux.

There is also a PR that changes the lookup rules so that all platforms are checked, which would also solve your problem. It has been stale for a while though.

If anyone is wondering how I solved my situation, I simply added

alias tldr='tldr --platform linux '

in my .bashrc
