#! bash oh-my-bash.module

# Oxygen segment for the oh-my-bash powerline themes.

#

# Install: copy this file to "$OSH_CUSTOM/oxy.sh" (default ~/.oh-my-bash/custom/)

# and open a new shell. Custom files load before the theme, so the

# POWERLINE_PROMPT default below adds the "oxy" segment next to the Git one;

# set POWERLINE_PROMPT yourself to arrange segments differently.

#

# The segment shows: icon, bookmark, working-copy change id, a state glyph

# (✔ clean, ✎ uncommitted changes, ‼ conflicts), and ↑n/↓n against origin.

# Its colour follows the state. It costs one `oxy prompt` call, a few

# milliseconds, and prints nothing outside an Oxygen repository.
