“swift ./-” does the same as “swift -”

[Frizlab]

Description

swift ./- should try and read the file named - in the current folder. Instead it reads from stdin, just like swift -.

Reproduction

1. Create a swift file name - in your cwd;
2. Run swift ./-

Expected behavior

Swift should execute the file just created.

Environment

swift-driver version: 1.87.3 Apple Swift version 5.9.2 (swiftlang-5.9.2.2.56 clang-1500.1.0.2.5)
Target: arm64-apple-macosx14.0

To solve this issue, try running swift run ./-

It works for me when I try this.

@sananthanarayan I get error: Could not find Package.swift in this directory or any of its parent directories. when doing swift run ./- (as expected…)

I have also tried with zero f these 2 commands, both work for me. Do they work for you?

• swift ./-

• swift "$(pwd)/-"

[sananthanarayan]

or with the swift run command try this modified version of that:

swift run -- ./-

Seems like a driver issue, swift -### ./- outputs a frontend command with the path -, which the frontend then interprets as the stdin. FWIW adding -working-directory="$PWD" avoids the issue, since the driver will convert it to an absolute path.
