These widgets search a target string from the command history.
By default, the string before the cursor in the command line is used as the target string.
The target string may be input by the user using OPTS input or again (see below).
By default, the history entries that start from the target string are searched.
The history entries that contain the target string may be searched using OPTS substr (see below).
OPTS is a colon-separated list of the following fields:
-
backward(default) ... Start searching in forward direction, i.e., searching for older history entries. -
forward... Start searching in forward direction, i.e., searching for newer history entries. -
substr... Find history entries that contains the target string. -
input... Prompt the user to input the target string. -
again... Use the target string previously input by the user. -
hide-status... Do not show thensearchstatus of(nsearch #N: << !M >>) `NEEDLE'. -
immediate-accept... The widgetnsearch/exit---which is defautly bound to C-m and RET---immediately runs the command. -
action=ACTION... Specify the type of action taken when the search string is matched to a history entry. ACTION is one of the following values:-
goto(default) ... Go to the history entry. -
load... Load the text of the history entry without moving the current history position. This is Bash's default behavior. -
load-line... Replace the current line with the text content of the history entry -
load-command... Replace the current command with the text content of the history entry -
insert... Insert the text content of the history entry in the current position -
insert-line... Insert the text content of the history entry as a new line in the current position
-
-
point=POINT... Specify the cursor position after the action. POINT is one of the following values:-
begin... the beginning of the command line -
end... the end of the command line -
match-begin... the beginning of the matched part -
match-end(default) ... the end of the matched part
-
-
empty=EMPTY... Specify the special treatment on the empty command search.-
empty-search(default) ... Startnsearchwith an empty string. -
hide-status... Startnsearchwith an empty string but do not show the nsearch status. -
previous-search... Startnsearchwith the previous search string. -
history-move... Go to the previous/next history entry without starting thensearch. The cursor position is set to the beginning of the command line to keep the string before the cursor empty.

In ble.sh, prompt string can be specified for various places such as PS1, PS2, PS0, bleopt prompt_rps1, read -p.
In addition to the standard Bash escape sequences of the form \..., there are also a few extensions.
Graphic attributes can be specified by the gspec format or the format used in ble-face face=[TYPE:]SPEC.
In addition to TYPE accepted by ble-face, face can also be used as a synonym of copy.
# Example
PS1='[\g{bold,fg=green}\u\g{none}@\g{bold,fg=navy}\h\g{none}]\$ 'function ble/prompt/backslash:X {
ble/prompt/print STRING
ble/prompt/process-prompt-string PROMPT_STRING
ble/prmopt/unit/add-hash '$VARNAME'
}
PS1='[\X]\$ 'In addition to the prompt sequences defined by Bash, user-defined sequences can be added and specified in the prompt string.
A sequence \X can be defined by creating a shell function named ble/prompt/backslash:X.
In the shell function, the string to be inserted in the prompt can be added by
calling ble/prompt/print STRING or ble/prompt/process-prompt-string PROMPT_STRING.
The former form inserts the literal argument in the prompt
while the latter processes the argument as another prompt string,
i.e., the prompt sequences and shell expansions in the argument will be processed.
By calling ble/prompt/unit/add-hash '$VARNAME', the dependencies of the expanded results on arbitrary variables can be declared.
The corresponding prompts will be automatically updated on the variable changes.
The prompt sequence \q{NAME ARGS...} (v0.4) can be used to call
the named prompt sequence with arguments.
The named prompt sequences are processed by calling the shell function ble/prompt/backslash:NAME ARGS....
# Example: User-defined sequence "hello"
function ble/prompt/backslash:hello {
ble/prompt/print "Hello, ${1:-world}!"
}
PS1='[\q{hello $USER}]\$ '4.13.3 Prompt sequence \q{row} (v0.4)†
This is expanded to the current line number in the command line.
\q{row} # Example result: 1
4.13.4 Prompt sequence \q{column} (v0.4)†
This is expanded to the current column number in the command line.
\q{column} # Example result: 5
4.13.5 Prompt sequence \q{position} (v0.4)†
This is expanded to the current line and column numbers in the command line. The format can be specified to the first argument as a printf format string.
\q{position} # Example result: (1,5)
\q{position line %s, column %s} # Example result: line 1, column 5
4.13.6 Prompt sequence \q{point} (v0.4)†
This is expanded to the current offset of the cursor position in the command line string.
\q{point} # Example result: 3
4.13.7 Prompt sequence \q{mark} (v0.4)†
This is expanded to the current offset of the mark position in the command line string.
\q{mark} # Example result: 0
4.13.8 Prompt sequence \q{history-index} (v0.4)†
This is expanded to the current history index in the command history.
\q{history-index} # Example result: 0
4.13.9 Prompt sequence \q{history-percentile} (v0.4)†
This is expanded to the percentile position of the current history position in the command history.
\q{history-percentile} # Example result: 100%
In addition to the standard prompts of Bash, such as PS1, PS2, PS0, additional prompts listed in this section are also available in ble.sh.
See also the editing-mode specific prompts:
4.14.1 Bleopt prompt_rps1 (Prompt string) (v0.3)†
# default
bleopt prompt_rps1= # ble-0.4
bleopt rps1= # ble-0.3 (obsolete)The option sets the right prompt.
# Example: show current time
bleopt prompt_rps1='\t'4.14.2 Bleopt prompt_ps1_final (Prompt string) (v0.4)†
# default
bleopt prompt_ps1_final=When a non-empty value is specified, the prompt is replaced by this value before leaving the current command line.
4.14.3 Bleopt prompt_ps1_transient (Colon-separated list) (v0.4)†
# default
bleopt prompt_ps1_transient=This is a colon-separated list of always, same-dir and trim.
When prompt_ps1_final is empty and this option has a non-empty value,
the prompt specified by PS1 is erased on leaving the current command line.
If the value contains a field trim, only the last line of multiline PS1 is preserved and the other lines are erased.
Otherwise, the command line will be redrawn as if PS1= is specified.
When a field same-dir is contained in the value
and the current working directory is different from the final directory of the previous command line,
this option prompt_ps1_transient is ignored.
4.14.4 Bleopt prompt_rps1_final (Prompt string) (v0.4)†
# default
bleopt prompt_rps1_final=When a non-empty value is specified, the right prompt is replaced by this value before leaving the current command line.
4.14.5 Bleopt prompt_rps1_transient (Empty/Non-empty) (v0.3)†
# default
bleopt prompt_rps1_transient= # ble-0.4
bleopt rps1_transient= # ble-0.3 (obsolete)When prompt_rps1_final is empty and this option has a non-empty value,

# default
bleopt prompt_screen_title=This option is only effective inside terminal multiplexers such as GNU screen and tmux.
When a non-empty value is specified,
the window title of the terminal multiplexer is replaced by the specified string
using ESC k ... ST just before showing PS1.
4.14.8 Bleopt prompt_term_status (Prompt string) (v0.4)†
# default
bleopt prompt_term_status=This option is only effective when terminfo entries tsl and fsl (or termcap entries ts and ds) are available.
When a non-empty value is specified,
the content of the status line is replaced using terminfo just before showing PS1.
4.14.9 Bleopt prompt_status_line (Prompt string) (v0.4)†
# default
bleopt prompt_status_line=This option specifies the content of the status line which would be shown at the bottom line of the terminal. When the evaluated value is empty, the status line is disabled.
See also the following settings, bleopt prompt_status_align and ble-face promtp_status_line, to control the text alignment and the background face of the status line.
4.14.10 Bleopt prompt_status_align (Enumerable) (v0.4)†
# default
bleopt prompt_status_align=$'justify=\r'This option specifies the position of the content of the status line.
The values left, right, center, or justify=CHAR can be specified.
When justify=CHAR (where CHAR is a user-specified character) is set,
the expanded results are split by the character CHAR
and arranged to fill the line just like the text justification.
4.14.11 Face prompt_status_line (v0.4)†
# default
ble-face prompt_status_line='fg=231,bg=240'This face specifies the background face of the status line.
4.15.1 Bleopt indent_offset (Arithmetic) (v0.2)†
# default
bleopt indent_offset=4This option specifies the unit width of indentation.
4.15.2 Bleopt indent_tabs (Arithmetic) (v0.2)†
# default
bleopt indent_tabs=1This option controls whether tabs are used for indentation or not.
If 0 is specified, indentation will be made with only spaces,
or otherwise tabs are also used for indentation.
4.15.3 Bleopt edit_forced_textmap (Arithmetic) (v0.2)†
# default
bleopt edit_forced_textmap=1This option controls the usage of the layout information
for the operations such as movement up, down.
If this option has the value 0,
the layout information is used only when it is up to date.
Otherwise, when the layout information is out of date,
it is updated to be used for the operations.
4.15.4 Bleopt edit_line_type (Enumerable) (v0.4)†
# default
bleopt edit_line_type=logicalThis 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.
4.15.5 Bleopt edit_magic_expand (Colon-separated list) (v0.4)†
# default
bleopt edit_magic_expand=history:sabbrevThis option specifies the set of expansions performed by magic-space with a colon-separated list of expansion types.
The values history, sabbrev, alias, and autocd can be specified.
4.15.6 Bleopt edit_magic_opts (Colon-separated list) (v0.4)†
# default
bleopt edit_magic_opts=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.
4.15.7 Bleopt edit_magic_accept (Colon-separated list) (v0.4)†
# default
bleopt edit_magic_accept=verify-syntaxThis option specifies the expansions performed on accept-line by a
colon-separated list. The expansion is performed in a similar way as Bash's
history expansion. When sabbrev, alias, autocd, and history is
specified, the respective expansions are attempted on the command line. The
history expansion performed by history is identical to the one enabled by the
shell option set -H. When verify is specified, if sabbrev, alias, or
autocd expansions changed the command line, the execution of the command line
is canceled so the user can examine or continue to edit the expanded line. The
history expansion can be controlled by shopt -s histverify in a similar
manner. When verify-syntax is specified and any expansions change the
command string, a syntax check is performed. The command execution is canceled
when the command string is not syntactically complete. When history-line is
specified, the history expansion replaces the command line instead of just
printing the expansion result.
4.15.8 Bleopt delete_selection_mode (Empty/Non-empty) (v0.2)†
# default
bleopt delete_selection_mode=1This option controls the behavior of insertion when the selection is activated. If this option has a non-empty value, the contents of the selection is deleted before characters are inserted. If this option is empty, the selection is cleared before characters are inserted.
4.15.9 Bleopt undo_point (v0.2)†
# default
bleopt undo_point=endThis option specifies the cursor position after undo.
If the value is end, the cursor is moved to the end of the dirty section.
If the value is beg, the cursor is moved to the beginning of the dirty section.
Otherwise, the cursor position is restored to the original position when the state is recorded.
4.15.10 Bleopt history_preserve_point (Empty/Non-empty)†
# default
bleopt history_preserve_point=This option specifies the cursor position after the move between the history entries.
If a non-empty value is specified, ble.sh tries to preserve the position.
When the string after the move is shorter than the original position, the cursor position is moved to the end of text.
If the value is empty, the cursor position is moved to the end of text when it moved to the older history entry,
or the beginning of text when it moved to the recent history entry.
4.15.11 Bleopt term_cursor_external (Arithmetic) (v0.2)†
# default
bleopt term_cursor_external=0This option controls the cursor shape when external commands are executed.
The value is specified with the parameter of DECSCUSR.
It is enabled when terminfo (or termcap) has the entry Ss.
If your terminal actually supports DECSCUSR even though it is not shown up in terminfo,
please add the following setting to ~/.blerc.
_ble_term_Ss=$'\e[@1 q'4.15.12 Bleopt term_stty_restore (Empty/Non-empty) (v0.4)†
# default
bleopt term_stty_restore=When this setting is set to a non-empty value, ble.sh saves the TTY state at
the end of the command executation and restores it before the next command
execution. This adds a slight overload of running an extra call of stty.
Warning
If this is enabled, when a command breaks the TTY state, the effect remains in later commands.
When this option is enabled in ~/.blerc or in ~/.bashrc, source ~/.bashrc or ble-update or ble-reload should not be executed in the
internal state such as in PROMPT_COMMAND. This is because ble.sh saves
the TTY state at the point of setting term_stty_restore as the intial
external TTY state. If source ~/.bashrc or ble-update or ble-reload is
executed in the internal state, the internal state can be unexpectedly
captured as the external TTY state.
4.15.13 Bleopt allow_exit_with_jobs (Empty/Non-empty) (v0.3)†
# default
bleopt allow_exit_with_jobs=If the value is empty,
the shell will not exit with delete-forward-char-or-exit (defaultly to which C-d is bounded)
when there are remaining jobs.
If a non-empty value is specified, the shell exits even if there are remaining jobs.
4.15.14 Bleopt prompt_eol_mark (ANSI escape sequences) (v0.3)†
# default
bleopt prompt_eol_mark=$'\e[94m[ble: EOF]\e[m'This option specifies the string when the command did not end at the beginning of line in the terminal.
4.15.15 Bleopt prompt_ruler (Empty/Enumerate/ANSI escape sequences) (v0.4)†
# default
bleopt prompt_ruler=This option specifies the ruler between the previous command and the prompt (like powerlevel10k POWERLEVEL9K_PROMPT_{ADD_NEWLINE,SHOW_RULER,RULER_*}).
When the empty value is specified, the ruler is disabled. This is the default.
When the value empty-line is specified, an empty line is inserted between the command and the prompt.
When the other values are specified, the value is interpreted as an ANSI sequences, and the result is repeated to fill a line.
4.15.16 Bleopt prompt_command_changes_layout (Empty/Non-empty) (v0.4)†
# default
bleopt prompt_command_changes_layout=This option specifies whether the commands called from the blehook PRECMD or the variable PROMPT_COMMAND output texts to the terminal and changes the layout.
When a non-empty value is specified, ble.sh resets the layout before running the hooks PRECMD and PROMPT_COMMAND and restores the layout after running the hooks.
When a empty value is specified, ble.sh assumes that these hooks do not output texts to the terminal and do not changes the cursor positions and skip the special treatment.
4.15.17 Bleopt exec_restore_pipestatus (Empty/Non-empty) (v0.4)†
# default
bleopt exec_restore_pipestatus=
# restore PIPESTATUS
bleopt exec_restore_pipestatus=1If this option is set to a non-empty value,
ble.sh restores the values of PIPESTATUS of the previous command before running the next user command.
By default, this is turned off because it adds extra execution costs.
The values of PIPESTATUS of the previous command are always available with the array BLE_PIPESTATUS regardless of this setting.
4.15.18 Bleopt edit_marker (ANSI escape sequences) (v0.4)†
# default
bleopt edit_marker=$'\e[94m[ble: %s]\e[m'This setting defines the default style of the markers (such as [ble: ...]) used by ble.sh for the normal notifications.
When it is set to an empty string, the marker is disabled (unless additional information other than the marker needs to be output after the marker).
This default style can be overridden by specific mark settings, such as exec_elapsed_mark and exec_exit_mark.
4.15.19 Bleopt edit_marker_error (ANSI escape sequences) (v0.4)†
# default
bleopt edit_marker_error=$'\e[91m[ble: %s]\e[m'This setting defines the default style of the markers (such as [ble: ...]) used by ble.sh for the error information.
When it is set to an empty string, the marker is disabled (unless additional information other than the marker needs to be output after the marker).
This default style can be overridden by specific mark settings, such as exec_errexit_mark.
4.15.20 Bleopt exec_errexit_mark (ANSI escape sequences) (v0.4)†
# default
bleopt exec_errexit_mark=$'\e[91m[ble: exit %d]\e[m'This option specifies the string printed when the command exited with non-zero exit status. When the value is empty, the exit status line will not be shown.
4.15.21 Bleopt exec_elapsed_mark (ANSI escape sequences) (v0.4)†
# default
bleopt exec_elapsed_mark=$'\e[94m[ble: elapsed %s (CPU %s%%)]\e[m'This option specifies the format of the command execution time report. The format takes two arguments: the first is the string that explains the elapsed time, and the second is a number that represents the percentage of CPU core usage.
4.15.22 Bleopt exec_elapsed_enabled (Arithmetic) (v0.4)†
# default
bleopt exec_elapsed_enabled='usr+sys>=10000'This option specifies the condition that the command execution time report is displayed after the command execution.
The condition is specified by an arithmetic expression, where a non-zero result causes displaying the report.
In the arithmetic expression, variables real, {usr,sys}{,_self,_child}, and cpu can be used.
real represents the elapsed time.
usr and sys represent the user and system time, respectively.
The suffixes _self and _child represent the part consumed in the main shell process and the other child processes including subshells and external programs, respectively.
cpu represents the percentage of the CPU core usage in integer, which can be calculated by (usr+sys)*100/real.
The other time values are all in unit of milliseconds.
4.15.23 Bleopt exec_exit_mark (ANSI escape sequences) (v0.4)†
# default
bleopt exec_exit_mark=$'\e[94m[ble: exit]\e[m'This setting specifies the marker printed when the bash session ends. When an empty string is specified, the marker is disabled.
4.15.24 Bleopt history_share (Empty/Non-empty) (v0.4)†
# default
bleopt history_share=When this option has a non-empty value,
the history is synchronized to $HISTFILE every time a command is executed.
4.15.25 Bleopt info_display (Enumerable) (v0.4)†
# default
bleopt info_display=topThis 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.
4.15.26 Bleopt accept_line_threshold (Arithmetic) (v0.4)†
# default
bleopt accept_line_threshold=5This option controls the behavior of widget accept-single-line-or-newline in the single-line mode.
If this option is evaluated to a negative integer, the command is always executed.
If this option is evaluated to 0, the widget inserts a newline when there is unprocessed user inputs.
If this option is evaluated to a positive integer n,
the widget inserts a newline when there is n or more user inputs.
4.15.27 Bleopt line_limit_type (Enumerable) (v0.4)†
# default
bleopt line_limit_type=noneThis 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.
Note
When the value editor is specified, bleopt history_limit_length is recommended to be less than or equal to bleopt line_limit_length.
Otherwise, the text editor may be unexpectedly executed in navigating through the history.
4.15.28 Bleopt line_limit_length (Arithmetic) (v0.4)†
# default
bleopt line_limit_length=10000This option specifies the capacity of the command line in the number of characters. The number 0 or negative numbers means the unlimited capacity.
4.15.29 Bleopt history_limit_length (Arithmetic) (v0.4)†
# default
bleopt history_limit_length=10000This 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.
4.15.30 Bleopt history_erasedups_limit (Empty/Arithmetic) (v0.4)†
# default
bleopt history_erasedups_limit=0This 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 count 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.
