fix(fish-completions): don't execute with `env` #57

Amolith · 2025-12-04T18:58:20Z

Using env broke Fish completions because command is a Fish builtin while env is an external program unaware of what Fish does and doesn't provide:

env: ‘command’: No such file or directory

Fish supports FIELD=val natively, so we can just remove env.

Walkthrough

Modified fish shell completion script to set environment variables directly instead of using the env builtin command. The change affects how WTP_SHELL_COMPLETION=1 is passed to the wtp command invocation, aligning source code and test data accordingly.

Changes

Cohort / File(s)	Summary
Fish completion env variable assignment `cmd/wtp/completion_config.go`, `cmd/wtp/testdata/completion/fish_expected.fish`	Replaced `env WTP_SHELL_COMPLETION=1 command wtp` syntax with direct shell variable assignment `WTP_SHELL_COMPLETION=1 command wtp` in fish completion logic and corresponding test expectations

Poem

🐰 In the sea of shells, a fish swims free,
No env wrapper needed, just WTP!
Direct assignment flows cleaner, you see,
A hop and a skip—simpler syntax, hurray! 🎣
