Overview

Glazed renders help pages through Glamour, which auto-detects whether the output target prefers a light or dark palette. Because the help system now writes to stdout by default, style detection looks at the stdout file descriptor unless you override the writer (see help_cmd.SetHelpWriter). If you route help somewhere else—os.Stderr, a file, or an in-memory buffer—the detection logic follows that writer.

When automatic detection misbehaves (tmux panes, nested SSH, etc.) you can pin the style explicitly:

• Set the COLORFGBG environment variable so Glamour can infer light vs. dark themes in terminals that hide this metadata.
• Set GLAMOUR_STYLE to "light", "dark", or "notty" to force a specific palette. "notty" is ideal for pipelines, CI logs, or anywhere ANSI colors should be suppressed.
• If you prefer the legacy “help on stderr” behavior—for example to keep stdout clean for machine-readable output—call help_cmd.SetHelpWriter(os.Stderr) during startup. Glamour will then use stderr for its TTY checks.

Refer to the Glamour style documentation for the complete list of built-in themes and customization options.
