Variables ¶
var IsStdinTerminal = func() bool { fi, err := os.Stdin.Stat() if err != nil { return false } return fi.Mode()&os.ModeCharDevice != 0 }
IsStdinTerminal reports whether stdin is connected to a terminal. dotdrift uses it to decide whether a generated mise hook task may opt into interactive mode (interactive = true): when stdin is a TTY, an interactive command inside a hook (e.g. sudo) gets a controlling terminal so it can disable echo, instead of reading the password with echo on. Stdlib-only char-device check (golang.org/x/term is not vendored). A variable so tests and callers can substitute it.
Functions ¶
func EchoCommand ¶
EchoCommand writes the set -x-style echo line "+ <argv>\n" to w.
func ShellJoin ¶
ShellJoin renders argv as a shell-style command line: elements are joined with single spaces; any element containing whitespace or a single quote is single-quoted (each ' escaped as '\”), bash set -x style. Simple elements pass through unquoted. Empty argv joins to the empty string.
Types ¶
type LockedWriter ¶ added in v0.8.0
LockedWriter serializes concurrent writes to W. os/exec spawns one copy goroutine per stream when Stdout and Stderr are different writers, so two MultiWriters capturing into one bytes.Buffer race (and silently lose writes) without it.
