failed to create glamour renderer: %w

Error message

failed to create glamour renderer: %w

What it means

getGlamourRenderer builds a glamour.TermRenderer for terminal markdown rendering and wraps any construction failure. glamour.NewTermRenderer fails mainly when the style name is invalid or style assets can't be loaded. Because package init() calls this, a bad GLAMOUR_STYLE env var can break the package at startup.

Solutions

1. Check GLAMOUR_STYLE value; unset it or set it to a valid standard style (dark, light, notty, ascii)
2. If using a custom style JSON, verify the file path exists and is valid JSON
3. Run with GLAMOUR_STYLE unset to confirm auto-style works
4. Update glamour to a version whose style set matches the configured name

Example fix

// before
export GLAMOUR_STYLE=drak
// after
export GLAMOUR_STYLE=dark  # or unset GLAMOUR_STYLE

if style := os.Getenv("GLAMOUR_STYLE"); style != "" {
    for _, valid := range []string{"dark","light","notty","ascii","dracula","nord","tokyo-night"} {
        if style == valid { goto ok }
    }
    // unknown style: unset or fix GLAMOUR_STYLE before running
}

r, err := getGlamourRenderer()
if err != nil {
    // fallback: render plain text instead of failing
    fmt.Println(input)
    return nil
}

When it happens

Trigger: GLAMOUR_STYLE env var is set to an unknown style name (anything not dark/light/notty/ascii/dracula/etc. or a valid style JSON path), or the installed glamour version cannot load its style definitions.

Common situations: Developers set GLAMOUR_STYLE=drak (typo) or a custom style file path that doesn't exist; CI environments with a stale GLAMOUR_STYLE exported in shell profile; version upgrade changed valid style names.
