 ##-----------------------------------------------------------------------------
 ## Basic settings
 
 
 ## The following setting specifies the input encoding. Currently only "UTF-8"
 ## and "C" is available.
 
 #bleopt input_encoding=UTF-8
 
 
 ## The following setting specifies the pager used by ble.sh.  This is used to
 ## show the help of commands (f1).
 
 #bleopt pager=less
 
 ## The following setting specifies the editor used by ble.sh.  This is used for
 ## the widget edit-and-execute (C-x C-e) and editor for a large amount of
 ## command line texts.  Possible values include, for example, "vim", "emacs
 ## -nw" and "nano".
 
 #bleopt editor=vim
 
 
 ## The following settings sets the behavior of visible bells (vbell).
 ## "vbell_duration" sets the time duration to show the vbell. "vbell_align"
 ## controls the position of vbell. The value "left" (default) specifies that
 ## the vbell should be shown up on the top left corner of the terminal. The
 ## values "center" and "right" specify that the vbell is shown on the top
 ## center and the top right corner, respectively.
 
 #bleopt vbell_default_message=' Wuff, -- Wuff!! '
 #bleopt vbell_duration=2000
 #bleopt vbell_align=right
 
 
 ##-----------------------------------------------------------------------------
 ## Line editor settings
 
 
 ## The following settings turns on/off the audible bells and visible bells for
 ## errors while user edit. The non-empty value turns on the bells.
 
 #bleopt edit_abell=1
 #bleopt edit_vbell=
 
 
 ## The following setting turns on the delayed load of history when an non-empty
 ## value is set.
 
 #bleopt history_lazyload=1
 
 
 ## The following setting turns on the delete selection mode when an non-empty
 ## value is set. When the mode is turned on the selection is removed when a
 ## user inserts a character.
 
 #bleopt delete_selection_mode=1
 
 
 ## The following settings control the indentation. "indent_offset" sets the
 ## indent width. "indent_tabs" controls if tabs can be used for indentation or
 ## not. If "indent_tabs" is set to 0, tabs will never be used. Otherwise
 ## indentation is made with tabs and spaces.
 
 #bleopt indent_offset=4
 #bleopt indent_tabs=1
 
 
 ## "undo_point" controls the cursor position after "undo". When "beg" or "end"
 ## is specified, the cursor will be moved to the beginning or the end of the
 ## dirty section, respectively. When other values are specified, the original
 ## cursor position is reproduced.
 
 #bleopt undo_point=end
 
 
 ## The following setting controls forced layout calculations before graphical
 ## operations. When a non-empty value is specified, the forced calculations are
 ## enabled. When an empty string is set, the operations are switched to logical
 ## ones.
 
 #bleopt edit_forced_textmap=1
 
 
 ## The following option controls the interpretation of lines when going to the
 ## beginning or the end of the current line.  When the value `logical` is
 ## specified, the logical line is used, i.e., the beginning and the end of the
 ## line is determined based on the newline characters in the edited text.  When
 ## the value `graphical` is specified, the graphical line is used, i.e., the
 ## beginning and the end of the displayed line in the terminal is used.
 
 #bleopt edit_line_type=graphical
 
 
 ## The following option specifies the set of expansions performed by
 ## magic-space with a colon-separated list of expansion types. "history",
 ## "sabbrev", and "alias" can be specified.
 
 #bleopt edit_magic_expand=history:sabbrev
 
 
 ## This option configures the detailed behavior of the widget "magic-space"
 ## with a colon-separated list.  If the field "inline-sabbrev-no-insert" is
 ## specified, the insertion of "SP" is skipped when the inline sabbrev is
 ## performed by "magic-space".
 
 #bleopt edit_magic_opts=
 
 
 ## The following option controls the position of the info pane where completion
 ## menu, mode names, and other information are shown.  When the value "top" is
 ## specified, the info pane is shown just below the command line.  When the
 ## value "bottom" is specified, the info pane is shown at the bottom of the
 ## terminal.  The default is "top".
 
 #bleopt info_display=top
 
 
 ## The following settings controls the prompt after the cursor left the command
 ## line.  "prompt_ps1_final" contains a prompt string.  "prompt_ps1_transient"
 ## is a colon-separated list of fields "always", "same-dir" and "trim".  The
 ## prompt is replaced by "prompt_ps1_final" if it has a non-empty value.
 ## Otherwise, the prompt is trimmed leaving the last line if
 ## "prompt_ps1_transient" has a field "trim".  Otherwise, the prompt vanishes
 ## if "prompt_ps1_transient" has a non-empty value.  When
 ## "prompt_ps1_transient" contains a field "same-dir", the setting of
 ## "prompt_ps1_transient" is effective only when the current working directory
 ## did not change since the last command line.
 
 #bleopt prompt_ps1_final=
 #bleopt prompt_ps1_transient=trim
 
 
 ## The following settings controls the right prompt. "prompt_rps1" specifies
 ## the contents of the right prompt in the format of PS1.  When the cursor
 ## leaves the current command line, the right prompt is replaced by
 ## "prompt_rps1_final" if it has a non-empty value, or otherwise, the right
 ## prompt vanishes if "prompt_rps1_transient" is set to a non-empty value,
 
 #bleopt prompt_rps1='\w'
 #bleopt prompt_rps1_final=
 #bleopt prompt_rps1_transient=''
 
 
 ## The following settings specify the content of terminal titles and status
 ## lines.  "prompt_xterm_title" specifies the terminal title which can be set
 ## by "OSC 0 ; ... BEL".  "prompt_screen_title" is effective inside terminal
 ## multiplexers such as GNU screen and tmux and specifies the window title of
 ## the terminal multiplexer which can be set by "ESC k ... ST".
 ## "prompt_term_status" is only effective when terminfo entries "tsl" and "fsl"
 ## (or termcap entries "ts" and "ds") are available, and specifies the content
 ## of the status line which can be set by the terminfo entries.  When each
 ## setting has non-empty value, the content of corresponding title or status
 ## line is replaced just before PS1 is shown.
 
 #bleopt prompt_xterm_title=
 #bleopt prompt_screen_title=
 #bleopt prompt_term_status=
 
 
 ## The following settings control the status line.  "prompt_status_line"
 ## specifies the content of the status line.  If its value is empty, the status
 ## line is not shown.  "prompt_status_align" controls the position of the
 ## content in the status line.
 
 #bleopt prompt_status_line=
 #bleopt prompt_status_align=left
 
 
 ## "prompt_eol_mark" specifies the contents of the mark used to indicate the
 ## command output is not ended with newlines. The value can contain ANSI escape
 ## sequences.
 
 #bleopt prompt_eol_mark=$'\e[94m[ble: EOF]\e[m'
 
 
 ## "prompt_ruler" specifies the ruler between the previous command and the
 ## prompt (like powerlevel10k
 ## "POWERLEVEL9K_PROMPT_{ADD_NEWLINE,SHOW_RULER,RULER_*}").  When the empty
 ## value is specified, the ruler is disabled.  This is the default.  When the
 ## value "empty-line" is specified, an empty line is inserted between the
 ## command and the prompt.  When the other values are specified, the value is
 ## interpreted as an ANSI sequences, and the result is repeated to fill a line.
 
 #bleopt prompt_ruler=            # no ruler (default)
 #bleopt prompt_ruler=empty-line  # empty line
 #bleopt prompt_ruler=$'\e[94m-'  # blue line
 
 
 ## "prompt_command_changes_layout" specifies whether the commands called from
 ## the blehook PRECMD or the variable PROMPT_COMMAND output texts to the
 ## terminal and changes the layout.  When a non-empty value is specified,
 ## ble.sh resets the layout before running the hooks PRECMD and PROMPT_COMMAND
 ## and restores the layout after running the hooks.  When a empty value is
 ## specified, ble.sh assumes that these hooks do not output texts to the
 ## terminal and do not changes the cursor positions and skip the special
 ## treatment.
 
 #bleopt prompt_command_changes_layout=   # PRECMD/PROMPT_COMMAND not output
 #bleopt prompt_command_changes_layout=1  # PRECMD/PROMPT_COMMAND may output
 
 
 ## "exec_restore_pipestatus" controls whether ble.sh restores PIPESTATUS of the
 ## previous user command.  When this option is set to a non-empty value,
 ## PIPESTATUS is restored.  This feature is turned off by default because it
 ## adds extra execution costs.  Note that the values of PIPESTATUS of the
 ## previous command are always available with the array BLE_PIPESTATUS
 ## regardless of this setting.
 
 #bleopt exec_restore_pipestatus=1  # restores PIPESTATUS
 
 
 ## "exec_errexit_mark" specifies the format of the mark to show the exit status
 ## of the command when it is non-zero.  If this setting is an empty string the
 ## exit status will not be shown.  The value can contain ANSI escape sequences.
 
 #bleopt exec_errexit_mark=$'\e[91m[ble: exit %d]\e[m'
 
 
 ## "exec_elapsed_mark" specifies the format of the command execution time
 ## report.  It takes two arguments: the first is the string that explains the
 ## elapsed time, and the second is a number that represents the percentage of
 ## CPU core usage.  "exec_elapsed_enabled" specifies the condition that the
 ## command execution time report is displayed after the command execution.  The
 ## condition is expressed by an arithmetic expression, where a non-zero result
 ## causes displaying the report.  In the arithmetic expression, variables
 ## "real", "{usr,sys}{,_self,_child}", and "cpu" can be used.  "real"
 ## represents the elapsed time.  "usr" and "sys" represent the user and system
 ## time, respectively.  The suffixes "_self" and "_child" represent the part
 ## consumed in the main shell process and the other child processes including
 ## subshells and external programs, respectively.  "cpu" represents the
 ## percentage of the CPU core usage in integer, which can be calculated by
 ## "(usr+sys)*100/real".  The other values are all in unit of milliseconds.
 
 #bleopt exec_elapsed_mark=$'\e[94m[ble: elapsed %s (CPU %s%%)]\e[m'
 #bleopt exec_elapsed_enabled='usr+sys>=10000'
 
 
 ## The following setting controls the exit when jobs are remaining. When an
 ## empty string is set, the shell will never exit with remaining jobs through
 ## widgets. When an non-empty value is set, the shell will exit when exit is
 ## attempted twice consecutively.
 
 #bleopt allow_exit_with_jobs=
 
 
 ## The following setting controls the cursor position after the move to other
 ## history entries. When non-empty values are specified, the offset of the
 ## cursor from the beginning of the command line is preserved. When an empty
 ## value is specified the cursor position is the beginning or the end of the
 ## command lines when the move is to a newer or older entry, respectively.
 
 #bleopt history_preserve_point=
 
 
 ## The following setting controls the history sharing. If it has non-empty
 ## value, the history sharing is enabled. With the history sharing, the command
 ## history is shared with the other Bash ble.sh sessions with the history
 ## sharing turned on.
 
 #bleopt history_share=
 
 
 ## This option controls the target range in the command history for
 ## "erasedups", which is performed when it is specified in "HISTCONTROL".  When
 ## this option has an empty value, the target range is the entire history as in
 ## the plain Bash.  When this option evaluates to a positive integer "count",
 ## the target range is the last "n" entries in the command history.  When this
 ## option evaluates to a non-positive integer "offset", "offset" specifies the
 ## beginning of the target range relative to the history count at the session
 ## start.  The end of the target range is always the end of the command
 ## history.
 
 #bleopt history_erasedups_limit=       # entire history
 #bleopt history_erasedups_limit=0      # only new items added in this session
 #bleopt history_erasedups_limit=-1000  # new items and 1000 prev-session items
 #bleopt history_erasedups_limit=1000   # last 1000 items
 
 
 ## The following setting controls the behavior of the widget
 ## "accept-single-line-or-newline" in the single-line editing mode. The value
 ## is a subject of arithmetic evaluation. When it evaluates to negative
 ## integers, the line is always accepted. When it evaluates to 0, it enters the
 ## multiline editing mode when there is any unprocessed user inputs, or
 ## otherwise the line is accepted. When it evaluates to a positive integer "n",
 ## it enters the multiline editing mode when there is more than "n"unprocessed
 ## user inputs.
 
 #bleopt accept_line_threshold=5
 
 
 ## The following option controls the behavior when the number of characters
 ## exceeds the capacity specified by `line_limit_length`.  The value `none`
 ## means that the number of characters will not be checked.  The value
 ## `discard` means that the characters cannot be inserted when the number of
 ## characters exceeds the capacity.  The value `truncate` means that the
 ## command line is truncated from its end to fit into the capacity.  The value
 ## `editor` means that the widget `edit-and-execute` will be invoked to open an
 ## editor to edit the command line contents.
 
 #bleopt line_limit_type=none
 
 
 ## The following option specifies the capacity of the command line in the
 ## number of characters.  The number 0 or negative numbers means the unlimited
 ## capacity.
 
 #bleopt line_limit_length=10000
 
 
 ## The following option specifies the maximal number of characters which can be
 ## appended into the history.  When this option has a positive value, commands
 ## with the length longer than the value is not appended to the history.  When
 ## this option has a non-positive value, commands are always appended to the
 ## history regardless of their length.
 
 #bleopt history_limit_length=10000
 
 
 ##-----------------------------------------------------------------------------
 ## Terminal state control
 
 
 ## The following setting specifies the cursor type when commands are executed.
 ## The cursor type is specified by the argument of the control function
 ## DECSCUSR.
 
 #bleopt term_cursor_external=0
 
 
 ## The following settings, external and internal, specify the "modifyOtherKeys"
 ## states [the control function SM(>4)] when commands are executed and when
 ## ble.sh has control, respectively.
 
 #bleopt term_modifyOtherKeys_external=auto
 #bleopt term_modifyOtherKeys_internal=auto
 
 
 ## The following setting controls whether the kitty-keyboard-protocol sequences
 ## should pass-through the terminal multiplexers when the outermost terminal is
 ## kitty.  When this option has a non-empty string, the pass-through kitty
 ## protocol sequences are enabled.
 ##
 ## * This is intended to be used with tmux-3.4+.  This works with tmux-3.3a and
 ##   below as far as the user does not enable CapsLock or NumLock.  Note that
 ##   this might cause problems of keyboard inputs after detaching from tmux;
 ##   You might lose the control of the terminal applications that do not
 ##   support extended keys outside the terminal multiplexers.
 ##
 ## * This will cause the same problems when used with multiple windows in GNU
 ##   screen.  You will lose the control of the terminal applications without
 ##   the support for extended keys when there are more than one ble.sh session
 ##   or when there is at least one foreground ble.sh session in GNU screen.
 
 #bleopt term_modifyOtherKeys_passthrough_kitty_protocol=1
 
 ##-----------------------------------------------------------------------------
 ## Rendering options
 
 
 ## "tab_width" specifies the width of TAB on the command line. When an empty
 ## value is specified, the width in terminfo (tput it) is used.
 
 #bleopt tab_width=
 
 
 ## "char_width_mode" specifies the width of East_Asian_Width=A characters.
 ## When the value "east" is specified, the width is 2. When the value "west" is
 ## specified, the width is 1.  When the value "emacs" is specified, the width
 ## table (depending on characters) used in Emacs is used.  When the value
 ## "musl" is specified, the table for "wcwidth" of the musl C library in 2014
 ## is used [Note: recent versions of musl library is more conforming to Unicode
 ## so favor "west" or "east"].  When "auto" is specified, the character width
 ## mode is automatically selected based on interactions with the terminal.
 
 #bleopt char_width_mode=auto
 
 
 ## "char_width_version" specifies the Unicode version that char width
 ## determination bases on.  When "auto" is specified, ble.sh automatically
 ## tests the behavior of the terminal on startup and try to determine the
 ## appropriate version.  Supported versions are "4.1", "5.0", "5.2", "6.0",
 ## "6.1", "6.2", "6.3", "7.0", "8.0", "9.0", "10.0", "11.0", "12.0", "12.1",
 ## "13.0", "14.0", and "15.0".  The default value is "auto".
 
 #bleopt char_width_version=auto
 
 
 ## "emoji_width" specifies the width of emoji characters.  If an empty value is
 ## specified, special treatment of emoji is disabled.
 
 #bleopt emoji_width=2
 
 
 ## "emoji_version" specifies the version of Unicode Emoji.  Available values
 ## are 0.6, 0.7, 1.0, 2.0, 3.0, 4.0, 5.0, 11.0, 12.0, 12.1, 13.0, 13.1, 14.0,
 ## and 15.0.
 
 #bleopt emoji_version=13.1
 
 
 ## "emoji_opts" is a colon-separated list that represents the terminal
 ## capability for emojis.  When "tpvs" and "epvs" are specified, TPVS and EPVS
 ## (text/emoji presentation variation selectors), respectively, can be used to
 ## change he representation of emoji characters.  When "zwj" is specified, the
 ## emoji ZWJ sequences are supported.  When "ri" is specified, the flag emojis
 ## formed by two Regional_Indicators are supported.  When "unqualified" is
 ## specified, unqualified emojis are treated as emojis as well as the qualified
 ## emojis.
 
 #bleopt emoji_opts=ri
 
 
 ## This option specifies the type of the supported grapheme cluster of the
 ## terminal.  The empty string indicates that the terminal does not support the
 ## grapheme clusters.  The values "extended" and "legacy" indicate that the
 ## terminal supports the extended and legacy grapheme clusters, respectively.
 
 #bleopt grapheme_cluster=extended
 
 
 ## This option controls the behavior when ble.sh receives SIGWINCH.
 ## * When the value "redraw-safe" is specified, ble.sh redraws the new prompt
 ##   starting from the line of the current cursor position.
 ## * When the value "redraw-prev" is specified, ble.sh tries to go to the
 ##   beginning of the current prompt and overwrite the current one.  This is
 ##   similar to the behavior of GNU Readline.  This possibly erase the output
 ##   of the previous command because ble.sh tries to go to the beginning of the
 ##   current prompt assuming that the number of lines in the prompt does not
 ##   change by the terminal resizing.
 ## * When the value "redraw-here" is specified, ble.sh tries to determine the
 ##   number of lines that can be safely erased and go to the beginning of the
 ##   safe lines before the redraw.  This is the default behavior.  In
 ##   principle, this can also erase the previous outputs, but it would be
 ##   supposed to be rarely happen as far as the text reflowing of the terminal
 ##   behaves in a reasonable way.
 ## * When the value "clear" is specified, the terminal content is erased and
 ##   the new prompt will be drawn at the top of the terminal.  The previous
 ##   terminal contents including the command outputs will be lost.
 
 #bleopt canvas_winch_action=redraw-here
 
 ##-----------------------------------------------------------------------------
 ## User input settings
 
 ## The following setting sets the default keymap. The value "emacs" specifies
 ## that the emacs keymap should be used. The value "vi" specifies that the vi
 ## keymap (insert mode) should be used as the default. The value "auto"
 ## specifies that the keymap should be automatically selected from "emacs" or
 ## "vi" according to the current readline state "set -o emacs" or "set -o vi".
 
 #bleopt default_keymap=auto
 
 
 ## The following setting controls the treatment of isolated ESCs.  The value
 ## "esc" indicates that it should be treated as ESC.  The value "meta"
 ## indicates that it should be treated as Meta modifier.  The value "auto"
 ## indicates that the behavior will be switched to an appropriate side of "esc"
 ## or "meta" depending on the current keymap.
 
 #bleopt decode_isolated_esc=esc
 
 
 ## The following setting specifies the byte code used to abort the currently
 ## processed inputs. The default value 28 corresponds to "C-\".
 
 #bleopt decode_abort_char=28
 
 
 ## The following settings sets up the behavior for errors while user input
 ## decoding. "error_char" is the decoding error for the current character
 ## encoding. "error_cseq" indicates the unrecognized CSI sequences.
 ## "error_kseq" indicates the unbound key sequences. "abell" and "vbell" turn
 ## on/off the audible bells and visible bells on errors. If the variable is
 ## empty the bells are turned off, or otherwise turned on. "discard" controls
 ## if the chars/sequences will be discarded or processed in later stage. If a
 ## non-empty value is given, chars/sequences are discarded.
 
 #bleopt decode_error_char_abell=
 #bleopt decode_error_char_vbell=1
 #bleopt decode_error_char_discard=
 #bleopt decode_error_cseq_abell=
 #bleopt decode_error_cseq_vbell=1
 #bleopt decode_error_cseq_discard=1
 #bleopt decode_error_kseq_abell=1
 #bleopt decode_error_kseq_vbell=1
 #bleopt decode_error_kseq_discard=1
 
 
 ## This variable sets the limit to the count of recursive calls of keyboard
 ## macros.
 
 #bleopt decode_macro_limit=1024
 
 
 ## When a non-empty value is specified to this settings, the terminal's
 ## Bracketed Paste Mode (DEC mode 2004) is enabled.  This setting is
 ## synchronized with the readline variable "enable-bracketed-paste".
 
 #bleopt term_bracketed_paste_mode=on
 
 ##-----------------------------------------------------------------------------
 ## Settings for completion
 
 
 ## The following settings turn on/off the corresponding functionalities. When
 ## non-empty strings are set, the functionality is enabled. Otherwise, the
 ## functionality is inactive.
 
 #bleopt complete_auto_complete=1
 #bleopt complete_menu_complete=1
 #bleopt complete_menu_filter=1
 
 
 ## If "complete_ambiguous" has non-empty values, ambiguous completion
 ## candidates are generated for completion.
 
 #bleopt complete_ambiguous=1
 
 
 ## If "complete_contract_function_names" has non-empty values, the function
 ## name candidates are grouped by prefixes of the directory-like form "*/".
 
 #bleopt complete_contract_function_names=1
 
 
 ## By default, ble.sh does not allow rewriting the existing text if non-unique
 ## candidates does not contain the existing text.  If this setting has
 ## non-empty values, ble.sh rewrites the existing text.
 
 #bleopt complete_allow_reduction=1
 
 
 ## This option specifies the threshold to simplify the quotation type of the
 ## inserted word.  This option is evaluated as an arithmetic expression.  When
 ## this option evaluates to a negative value, the simplification of the
 ## quotation is disabled.  Otherwise, when the number of characters will be
 ## reduced by at least the specified value, the quotation is simplified.  The
 ## default is 0, which means that the quotation is simplified unless the number
 ## of characters increases by the simplification.
 
 #bleopt complete_requote_threshold=0
 
 
 ## If "complete_auto_history" has non-empty values, auto-complete searches
 ## matching command lines from history.
 
 #bleopt complete_auto_history=1
 
 
 ## The following setting controls the delay of auto-complete after the last
 ## user input. The unit is millisecond.
 
 #bleopt complete_auto_delay=100
 
 
 ## The setting "complete_auto_wordbreaks" is used as the delimiters for
 ## identifying words for M-right (auto-complete/insert-word).  The default
 ## value is $' \t\n'.  If the empty value is set, the default value is used.
 
 #bleopt complete_auto_wordbreaks=$' \t\n/'
 
 
 ## The setting "complete_auto_complete_opts" is a colon-separated list of
 ## options:
 ##
 ## - The option "suppress-after-complete" controls whether auto-complete is
 ##   enabled after TAB completions.  If "suppress-after-complete" is included,
 ##   auto-complete is enabled after TAB completions.  Otherwise, auto-complete
 ##   is disabled after TAB completions.
 
 #bleopt complete_auto_complete_opts=suppress-after-complete
 
 
 ## The setting "complete_auto_menu" controls the delay of "auto-menu".  When a
 ## non-empty string is set, auto-menu is enabled.  The string is evaluated as
 ## an arithmetic expression to give the delay in milliseconds.  ble.sh will
 ## automatically show the menu of completions after the idle time (for which
 ## user input does not arrive) reaches the delay.
 
 #bleopt complete_auto_menu=500
 
 
 ## When there are user inputs while generating completion candidates, the
 ## candidates generation will be canceled to process the user inputs. The
 ## following setting controls the interval of checking user inputs while
 ## generating completion candidates.
 
 #bleopt complete_polling_cycle=50
 
 
 ## A hint on the maximum acceptable size of any data structure generated during
 ## the completion process, beyond which the completion may be prematurely
 ## aborted to avoid excessive processing time.  "complete_limit" is used for
 ## TAB completion.  When its value is empty, the size checks are disabled.
 ## "complete_limit_auto" is used for auto-completion.  When its value is empty,
 ## the setting "complete_limit" is used instead. "complete_limit_auto_menu" is
 ## used for auto-menu.
 
 #bleopt complete_limit=500
 #bleopt complete_limit_auto=200
 #bleopt complete_limit_auto_menu=100
 
 
 ## The following setting controls the timeout for the pathname expansions
 ## performed in auto-complete.  When the word contains a glob pattern that
 ## takes a long time to evaluate the pathname expansion, auto-complete based on
 ## the filename is canceled based on the timeout setting.  The value specifies
 ## the timeout duration in milliseconds.  When the value is empty, the
 ## timeout is disabled.
 
 #bleopt complete_timeout_auto=5000
 
 
 ## The following setting controls the timeout for the pathname expansions to
 ## prepare COMP_WORDS and COMP_LINE for progcomp.  When the word contains a
 ## glob pattern that takes a long time to evaluate, the pathname expansion is
 ## canceled, and a noglob expansion is used to construct COMP_WORDS and
 ## COMP_LINE.  The value specifies ## the timeout duration in milliseconds.
 ## When the value is empty, the timeout is disabled.
 
 #bleopt complete_timeout_compvar=200
 
 
 ## The following setting specifies the style of the menu to show completion
 ## candidates. The value "dense" and "dense-nowrap" shows candidates separated
 ## by spaces. "dense-nowrap" is different from "dense" in the behavior that it
 ## inserts a new line before the candidates that does not fit into the
 ## remaining part of the current line. The value "align" and "align-nowrap"
 ## aligns the candidates. The value "linewise" shows a candidate per line.  The
 ## value "desc" and "desc-text" shows a candidate per line with description for
 ## each. "desc-text" is different from "desc" in the behavior that it does not
 ## interprets ANSI escape sequences in the descriptions.
 
 #bleopt complete_menu_style=align-nowrap
 
 
 ## When a non-empty value is specified to this setting, the matching text on
 ## the right of the cursor is removed on the insertion of the completion.  This
 ## setting is synchronized with the readline variable "skip-completed-text".
 
 #bleopt complete_skip_matched=on
 
 
 ## The following setting controls the detailed behavior of menu-complete with a
 ## colon-separated list of options:
 ##
 ## - When the option "insert-selection" is specified, the currently selected
 ##  menu item is temporarily inserted in the command line.
 
 #bleopt complete_menu_complete_opts=insert-selection
 
 
 ## When a non-empty value is specified to this setting, the highlighting of the

 #bleopt complete_menu_maxlines=10
 
 
 ## The following settings specify the prefix of the menu items.  "menu_prefix"
 ## specifies the default prefix for any menu-style.
 ## "menu_{align,desc,linewise,dense}_prefix" specify the prefixes in the

 ##-----------------------------------------------------------------------------
 ## Color settings
 
 ## The setting "term_index_colors" specifies the number of index colors used to
 ## specify colors in the terminal.  The value "auto" means that the use of
 ## index colors are determined based on the terminfo database and the value of
 ## TERM shell variable.  Otherwise, the value is evaluated as an arithmetic
 ## expression.  When it is evaluated to 256, the index colors are assumed to be
 ## xterm 256-color palette (16 basic + 6x6x6 color cube + 24 gray scale).  When
 ## it is evaluated to 88, the index colors are assumed to be xterm 88-color
 ## palette (16 basic + 4x4x4 color cube + 8 gray scale).  When it is evaluated
 ## to 0, ble.sh will never use the index colors to set colors.  When it is
 ## evaluated to other integers, the value specifies the maximum available
 ## index.
 
 #bleopt term_index_colors=256
 
 
 ## The setting "term_true_colors" specifies the format of 24-bit color escape
 ## sequences supported by your terminal.  The value "semicolon" indicates the
 ## format "CSI 3 8 ; 2 ; R ; G ; B m".  The value "colon" indicates the format
 ## "CSI 3 8 : 2 : R : G : B m".  The other value implies that the terminal does
 ## not support 24-bit color sequences.  In this case, ble.sh tries to output
 ## indexed color sequences or basic color sequences with properly reduced
 ## colors.
 
 #bleopt term_true_colors=semicolon
 
 
 ## The setting "filename_ls_colors" can be used to import the filename coloring
 ## scheme by the environment variable LS_COLORS.
 
 #bleopt filename_ls_colors="$LS_COLORS"
 
 
 ## The following settings enable or disable the syntax highlighting.  When the
 ## setting "highlight_syntax" has a non-empty value, the syntax highlighting is
 ## enabled.  When the setting "highlight_filename" has a non-empty value, the
 ## highlighting based on the filename and the command name is enabled during
 ## the process of the syntax highlighting.  Similarly, when the setting
 ## "highlight_variable" has a non-empty value, the highlighting based on the
 ## variable type is enabled.  All of these settings have non-empty values by
 ## default.
 
 #bleopt highlight_syntax=
 #bleopt highlight_filename=
 #bleopt highlight_variable=
 
 
 ## The following settings control the timeout and user-input cancellation of
 ## the pathname expansions performed in the syntax highlighting.  When the word
 ## contains a glob pattern that takes a long time to evaluate the pathname
 ## expansion, the syntax highlighting based on the filename is canceled based
 ## on the timeouts specified by these settings.  "highlight_timeout_sync" /
 ## "highlight_timeout_async" specify the timeout durations in milliseconds to
 ## be used for the foreground / background syntax highlighting, respectively.
 ## When the timeout occurred in the foreground, the syntax highlighting will be
 ## deferred to the background syntax highlighting.  When the timeout occurred
 ## in the background, the syntax highlighting for the filename is canceled.
 ## When the value is empty, the corresponding timeout is disabled.
 ## "syntax_eval_polling_interval" specifies the maximal interval between the
 ## user-input checking.
 
 #bleopt highlight_timeout_sync=500
 #bleopt highlight_timeout_async=5000
 #bleopt syntax_eval_polling_interval=50

 ## [The setting "openat_base" needs to be set before ble.sh is loaded or
 ## specified in the source options.  Therefore the value should be assigned
 ## directly to the shell variable "bleopt_openat_base" instead of using
 ## "bleopt" command.]
 ##
 ## This setting "openat_base" specifies the starting number of the file
 ## descriptors which ble.sh internally uses in Bash 4.0 or lower.  The value of
 ## this setting is used as the number for the first file descriptor of internal
 ## use, and the next value is used for the second file descriptor, and so on.
 ## When you want to use the default value 30 and succeeding number 31, 32,
 ## etc. for other purposes, please set to this settings another value which
 ## does not conflict with file descriptors of other purposes.
 
 # echo "usage: e.g. source out/ble.sh -o openat_base=30"
 
 
 ## It specifies the context of the command execution.  The value "gexec"
 ## specifies that the user command is evaluated in global contexts.  The value
 ## "exec" (ble-0.3 and before) specified that the user command is evaluated in
 ## a function, but the support is removed in ble-0.4 because this is only
 ## remained for a debugging purpose and not tested well.
 
 #bleopt internal_exec_type=gexec
 
 
 ## This option sets the message that Bash outputs when "C-d" is input by user.
 ## This value is used to detect that the user inputs "C-d" in Bash 3.
 
 #bleopt internal_ignoreeof_trap='Use "exit" to leave the shell.'
 
 
 ## This option controls the output of stack dump when assertion is failed in
 ## ble.sh.  When the value is evaluated to be non-zero, the stack dump is
 ## printed for assertion failures.
 
 #bleopt internal_stackdump_enabled=0
 
 
 ## When a non-empty value is specified to this option, the standard output and
 ## standard error from Bash is not output to the terminal.  When the value is
 ## empty, ble.sh tries to realize the line editing allowing Bash to output its
 ## own standard output and error.  This setting has a flickering problem and
 ## only left for debugging purpose, so it is not tested.  Normally a non-empty
 ## value should be specified so as to suppress the standard output and error
 ## from Bash.
