RETURNS previously conflated fish's $status exit code with genuine stdout/printed output, e.g. rm listing "0/1" as if they were print values rather than exit codes. Rename RETURNS to EXIT STATUS across all 83 documented functions, and reintroduce RETURNS as a distinct label reserved for the 15 functions that actually print to stdout. Update build-manual.py's ENTRY_HEADS to render Exit Status before Returns, manualtools.py's SECTIONS constant, and AGENTS.md's label order and label-usage guidance to match. Add two verify-manual.py regression tests: EXIT STATUS bodies must never contain stray stdout/printed language, and Returns: must always render after Exit Status: when both are present. Regenerate docs/fish-config.md.

# SYNOPSIS
|
|
# __config_settings_get_val <varname> <scope>
|
|
#
|
|
# DESCRIPTION
|
|
# Returns the current value of a named variable in the specified scope by
|
|
# parsing `set --show` output. Outputs "on", "off", or "DEFAULT" (when
|
|
# the variable is not set in that scope). Scope "session" maps to "global"
|
|
# in fish's internal terminology.
|
|
#
|
|
# ARGUMENTS
|
|
# varname Variable name without $ prefix
|
|
# scope "universal" or "session"
|
|
#
|
|
# EXIT STATUS
|
|
# 0 Always
|
|
#
|
|
# RETURNS
|
|
# "on", "off", or "DEFAULT", printed to stdout
|
|
#
|
|
# EXAMPLE
|
|
# set result (__config_settings_get_val __fish_config_op_aliases universal)
|
|
# # result == "on" | "off" | "DEFAULT"
