= Registers
|
|
|
|
== Description
|
|
|
|
Registers are named lists of text -instead of simply text- in order to interact
|
|
well with multiselection. They are used for various purposes, like storing
|
|
the last yanked text, or the captured groups associated with the selections.
|
|
|
|
== Interacting
|
|
|
|
*<c-r><c>*::
|
|
when in insert mode or in a prompt, insert the value stored in the
|
|
*c* register (single character)
|
|
|
|
*"<c>*::
|
|
in normal mode, select the *<c>* register (single character)
|
|
|
|
== Alternate names
|
|
|
|
Non alphanumeric registers have an alternative name that can be used
|
|
in contexts where only alphanumeric identifiers are possible.
|
|
|
|
== Default registers
|
|
|
|
Most commands using a register default to a specific one if not specified:
|
|
|
|
*"* (dquote)::
|
|
default copy register, used by yanking and pasting commands like *y*, *p*
|
|
and *R*
|
|
|
|
*/* (slash)::
|
|
default search register, used by regex based commands like *s*, ***,
|
|
*/* or *<a-k>*.
|
|
|
|
*@* (arobase)::
|
|
default macro register, used by *q* and *Q*
|
|
|
|
*^* (caret)::
|
|
default mark register, used by *z* and *Z*
|
|
|
|
*|* (pipe)::
|
|
default shell command register, used by command that spawn a subshell such as
|
|
*|*, *<a-|>*, *!* or *<a-!>*
|
|
|
|
== Special registers
|
|
|
|
Some registers are not general purposes, they cannot be written to, but they
|
|
contain some special data
|
|
|
|
*%* (percent)::
|
|
current buffer name
|
|
|
|
*.* (dot)::
|
|
current selection contents
|
|
|
|
*#* (hash)::
|
|
selection indices (first selection has 1, second has 2, ...)
|
|
|
|
*_* (underscore)::
|
|
null register, always empty
|
|
|
|
*:* (colon)::
|
|
last entered command
|
|
|
|
== Integer registers
|
|
|
|
Registers *1* to *9* hold the grouped sub-matches of the regular
|
|
expression used to make the last selection. Example: applying the
|
|
following regular expression to the date of the day would put the day of
|
|
the week in register *1*, the month in register *2*, and the day of the
|
|
month in register *3*, but select the entire date:
