fix(schedule): use term.GetSize() instead of COLUMNS env var for timeline wrapping by Copilot · Pull Request #222 · PinePeakDigital/buzz

Copilot · 2026-01-27T15:09:08Z

The buzz schedule timeline output relied on the COLUMNS environment variable for width detection. Most terminals don't set COLUMNS, causing the output to always default to 80 characters.

Changes

Replace os.LookupEnv("COLUMNS") with term.GetSize() syscall for actual terminal width
Add term.IsTerminal() check to handle piped output correctly
Promote github.com/charmbracelet/x/term from indirect to direct dependency

Implementation

// Before: unreliable env var lookup
width := 80
if w, ok := os.LookupEnv("COLUMNS"); ok {
    if n, err := strconv.Atoi(w); err == nil && n > 0 {
        width = n
    }
}

// After: syscall-based detection with terminal check
width := 80
fd := uintptr(os.Stdout.Fd())
if term.IsTerminal(fd) {
    if w, _, err := term.GetSize(fd); err == nil && w > 0 {
        width = w
    }
}

Timeline output now wraps correctly based on actual terminal dimensions across all environments.

Fixes Schedule command timeline output should wrap based on term width #218

✨ Let Copilot coding agent set things up for you — coding agent works faster and does higher quality work when set up for your repo.

Note

Improves buzz schedule timeline wrapping by detecting actual terminal width instead of relying on the COLUMNS env var.

Replace os.LookupEnv("COLUMNS") with term.IsTerminal() + term.GetSize() in displayTimeline (fallback to 80 cols)
Add direct dependency on github.com/charmbracelet/x/term in go.mod and import in main.go

Impact: More accurate wrapping in real terminals; piped/non-TTY output remains at 80 columns.

Pull request overview

This PR updates the buzz schedule timeline so that wrapping is based on the actual terminal width instead of the COLUMNS environment variable, improving behavior across more environments and handling non-TTY output correctly.

Changes:

Replace COLUMNS environment-variable-based width detection in displayTimeline with term.IsTerminal + term.GetSize for syscall-based terminal width detection.
Ensure piped/non-interactive output falls back to a default width of 80 when stdout is not a terminal.
Promote github.com/charmbracelet/x/term to a direct dependency in go.mod to support the new terminal width logic.

File	Description
main.go	Switches timeline width calculation from `COLUMNS` env lookup to `term.IsTerminal` + `term.GetSize` so wrapping reflects real terminal size, while retaining an 80‑column fallback.
go.mod	Adds `github.com/charmbracelet/x/term` as a direct dependency, supporting the new terminal width detection logic.
