The default swiftlint.path value is invalid on Windows

[tristanlabelle]

At The Browser Company, we're fixing SwiftLint to run on Windows and have produced builds of it. This allows us to use the vscode-swiftlint extension almost out-of-the-box, except that the default configuration fails to launch SwiftLint because the executable is launched via /usr/bin/env, which does not exist on Windows.

vscode-swiftlint/package.json

Lines 65 to 68 in 63b72ae

	"default": [
	"/usr/bin/env",
	"swiftlint"
	],

              "default": [
                "/usr/bin/env",
                "swiftlint"
              ],

Could we change the default to be only "swiftlint" to make it valid on all platforms? As needed, the /usr/bin/env could be prepended programatically on unix platforms in the extension code.

Hi @tristanlabelle, thanks for your suggestion! As I don't have access to a windows machine, I am not able to test the current build, but I created a beta build for this extension including your fix for windows. Could you give it a try?
1.8.4-beta.0

@vknabel I'm having issues with the vsix... I wonder if my VS Code is in a bad state 🤔

I installed it from the "Install from VSIX" command here:

That's weird. You did nothing wrong. Not sure why it isn't working though.
I created a new build with bumped dependencies. Eventually this solves your issue.
1.8.4-beta.1

[tristanlabelle]

My bad, I had swiftlint.enable = false in my user settings. The fix does not work, however. It's still trying to use /usr/bin/env.

[vknabel]

Sorry for the delay. I've taken some time off.

It seems like shell commands need to be executed differently on windows. Does this release solves your issue?

@vknabel I will try it out during the week (no computer access right now), but I was just thinking that a fix to this problem would be to implicitly prepend /usr/bin/env in the code if running on unix systems and the swiftlint.path contains no slashes (ie it is the unqualified name of an executable). Windows' CreateProcess function will look in the %Path% by default so that will work there too.

It make a bit more sense too because swiftlint.path is currently more of a command line prefix than a path.

[vknabel]

Back in time I did use a different function in the viscose extension which (in theory) would prefix everything with /usr/bin/env. But in some cases it did not work properly and it did not respect the local PATH variables of the user unless started from the shell itself.

On windows I now use the old way with a thin layer of compatibility. I hope this helps.

But I agree swiftlint.path is actually a prefix (an could in theory be set to swift run swiftlint etc).

[tristanlabelle]

I implemented this fix and it works on my machine: #73 . I also want to propose #72

[vknabel]

Thanks a lot for your work and enthusiasm! Sadly I am currently unable to provide the deserved time and energy to this project and the other two extensions (vscode-swiftformat and vscode-apple-swift-format).

I'd be happy if you are willing to support me and in the long term eventually take them over.
