NAME
Term::ReadLine::Zoid::ViCommand - a readline command mode
SYNOPSIS
This class is used as a mode under Term::ReadLine::Zoid, see there for usage details.
DESCRIPTION
This mode provides a "vi command mode" as specified by the posix spec for the sh(1)
utility. It intends to include at least all key-bindings mentioned by the posix spec for
the vi mode in sh(1). It also contains some extensions borrowed from vim(1) and some
private extensions.
This mode has a "kill buffer" that stores the last killed text so it can be yanked again.
This buffer has only one value, it isn't a "kill ring".
KEY MAPPING
Since ViCommand inherits from MultiLine, which in turn inherits from Term::ReadLine::Zoid,
key bindings are also inherited unless explicitly overloaded.
Control-d is ignored in this mode.
escape
Reset the command mode.
return
^J Return the current edit line to the application for execution.
^Z Send a SIGSTOP to the process of the application. Might not work when the application
ignores those, which is something shells tend to do.
i Switch back to insert mode.
I Switch back to insert mode at the begin of the edit line.
a Enter insert mode after the current cursor position.
A Enter insert mode at the end of the edit line.
m Switch to multiline insert mode, see Term::ReadLine::Zoid::MultiLine. (private
extension)
M Switch to multiline insert mode at the end of the edit buffer. (private extension)
R Enter insert mode with replace toggled on. (vim extension)
# Makes current edit line a comment that will be listed in the history, but won't be
executed.
Only works if the 'comment_begin' option is set.
= Display possible shell word completions, does not modify the edit line.
\ Do pathname completion (using File::Glob) and insert the largest matching part in the
edit line.
* Do pathname completion but inserts all matches.
[count] @ char
Regard the contents of the alias _char as a macro with editing commands. This seems a
rather obfuscated feature of the posix spec to me. See also below for the alias
command.
Note that the count argument is not posix compliant, but it seems silly not to use it.
[count] ~
Reverse case for count characters.
[count] .
Repeat the last non-motion command. If no count is specified the original count of
the command is used.
v Edit the buffer with the editor specified by the "EDITOR" environment variable or the
editor option, defaults to 'vi'.
This function requires the File::Temp module from cpan, which in turn needs File::Spec
and other packages. If these are not available this functions is disabled.
[count] l
[count] space
Move the cursor to the right.
[count] h
Move the cursor to the left.
[count] w
[count] W
Move the cursor to the begin of the next word or bigword.
(A bigword exists of non-whitespace chars, while a word exists of alphanumeric chars
only.)
[count] e
[count] E
Move the cursor to the end of the current word or bigword.
[count] b
[count] B
Move the cursor to the begin of the current word or bigword.
^ Move the cursor to the first non-whitespace on the edit line.
$ Move the cursor to the end of the edit line.
0 Move the cursor to the begin of the edit line.
[count] ⎪
Set the cursor to position count (1-based).
[count] f char
Set cursor to count'th occurrence of char to the right. The cursor is placed on char.
[count] F char
Set cursor to count'th occurrence of char to the left. The cursor is placed on char.
[count] t char
Set cursor to count'th occurrence of char to the right. The cursor is placed before
char.
[count] T char
Set cursor to count'th occurrence of char to the left. The cursor is placed after
char.
[count] ;
Repeat the last 'f', 'F', 't', or 'T' command. Count of last command is ignored.
[count] ,
Like ';' but with direction reversed.
[count] c motion
Delete characters between the current position and the position after the motion,
count applies to motion. After the deletion enter insert mode.
The "motion" 'c' deletes the current edit line.
C Delete from cursor to end of line and enter insert mode.
S Delete current line and enter insert mode.
[count] r char
Replace the character under the cursor (and the count characters next to it) with
char.
[count] _
Insert a white space followed by the last (or count'th) bigword from the previous
history entry ans enter insert mode.
Quotes are not respected by this function.
[count] x
Delete count characters and place them in the save buffer.
[count] X
Delete count characters before the cursor position and place them in the save buffer.
('x' is like 'delete', 'X' like backspace)
[count] d motion
Delete from the current cursor position to the position resulting from count times
motion. The deleted part will be placed in the save buffer.
The "motion" 'd' deletes the current line.
D Delete from the cursor position until the end of the line and put the deleted part in
the save buffer.
[count] y motion
Yank (copy) characters from the current cursor position to the position resulting from
count times motion to the save buffer.
the "motion" 'y' yanks the current line.
Y Like y but from cursor till end of line.
[count] p
Insert count copies of the the save buffer after the cursor.
[count] P
Insert count copies of the the save buffer before the cursor.
u Undo the last command that changed the edit line.
U Undo all changes.
TODO all changes since when ? since entering the command mode ?
[count] k
[count] -
Go count lines backward in history.
[count] j
[count] +
Go count lines forward in history.
[number] G
Go to history entry number number, or to the first history entry.
n Repeat the last history search by either the '/' or '?' minibuffers or the incremental
search mode.
N Repeat the last history search in the oposite direction.
: Opens a command mini buffer. This is a very minimalistic execution environment that
can for instance be used to modify options if the application doesn't provide a method
to do so. Also it is used for quick hacks ;)
The execution of this buffer happens entirely without returning to the application.
(This is a vim extension)
/ Opens a mini buffer where you can type a pattern to search backward through the
history.
The search patterns are not globs (as posix would have them), but are evaluated as
perl regexes.
An empty pattern repeats the previous search.
? Like '/' but searches in the forward direction.
^A If cursor is on a number, increment it. (This is a vim extension)
FIXME bit buggy
^X If cursor is on a number, decrement it. (This is a vim extension)
FIXME bit buggy
COMMANDS
These can be used from the ":" mini buffer. Some commands are borrowed from vim, but no
guarantee what so ever.
quit
Return undef to the application (like '^D' in insert mode).
set [+o⎪-o] [option=value]
Set a key-value pair in the options hash When the arg '+o' is given (or the option is
preceded by 'no') the option is deleted.
Can be used to change the ReadLine behaviour independent from the application.
ascii
Output ascii values for the char in the edit line on the cursor position.
testchr
Wait for a character input and output ascii values for it.
bindchr chr=keyname
Map a char (or char sequence) to a key name.
bindkey chr=sub { code }
Map a char (or char sequence) to a key name.
!, shell shellcode
Eval a system command. The '%' character in this string will be replace with the name
of a tmp file containing the edit buffer. After execution this tmp file will be read
back into the edit buffer. Of course you can use an backslash to escape a literal
'%'.
Note that this tmp file feature only works if you have File::Temp installed.
eval perlcode
Eval some perlcode for the most evil instant hacks. The ReadLine object can be called
as $self.
alias char=macro
Define a macro in an alias with a one character name. These can be executed with the
'@' command. Non alphanumeric keys like "\n" and "\e" can be inserted with the
standard perl escape sequences. You need to use "\\" for a literal '\'.
ATTRIBS
These can be accessed through the "Attribs" method (defined by the parent class).
aliases
This option is refers to a hash with aliases, used for the key binding for '@'. Note
that all aliases have a one character name prefixed with a "_", this is due to
historic implementations where the same hash is used for system aliases. We don't
support aliases for the shell command, to have that you should define your own shell
subroutine (see below).
editor
Editor command used for the 'v' binding. The string is run by the shell command. This
option defaults to the EDITOR enviroment variable or to "vi %".
shell
The value can be set to a CODE ref to handle the shell command from the mini-buffer
and the 'v' key binding. It should return the exit status of the command (like the
perlfunc "system()").
