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_set_value <varname> <type> <value>
|
|
#
|
|
# DESCRIPTION
|
|
# Sets a universal config variable from a config-settings value page,
|
|
# immediately and persistently. An empty <value> erases the variable so the
|
|
# built-in default takes over. List types split <value> on whitespace; all
|
|
# other types store it as a single value. When <varname> is a scrollback
|
|
# variable, the exported SCROLLBACK_HISTORY_* mirror is re-derived so the
|
|
# POSIX wrappers in the live session see the change without a re-login.
|
|
#
|
|
# ARGUMENTS
|
|
# varname Variable name without the $ prefix
|
|
# type "list" (whitespace-split) or any other tag (single value)
|
|
# value The new value; empty string erases (reset to default)
|
|
#
|
|
# EXIT STATUS
|
|
# 0 Always
|
|
#
|
|
# EXAMPLE
|
|
# __config_settings_set_value sponge_delay int 5
|
|
# __config_settings_set_value sponge_successful_exit_codes list "0 1 130"
|
|
# __config_settings_set_value __fish_scrollback_history_dir path ~/logs
|
|
# __config_settings_set_value __fish_user_dots_path path '' # reset
