\subsection commandline-description Description
`commandline` can be used to set or get the current contents of the command
line buffer.
With no parameters, `commandline` returns the current value of the command
line.
With `CMD` specified, the command line buffer is erased and replaced with
the contents of `CMD`.
The following options are available:
- `-C` or `--cursor` set or get the current cursor position, not
the contents of the buffer. If no argument is given, the current
cursor position is printed, otherwise the argument is interpreted
as the new cursor position.
- `-f` or `--function` inject readline functions into the
reader. This option cannot be combined with any other option. It
will cause any additional arguments to be interpreted as readline
functions, and these functions will be injected into the reader, so
that they will be returned to the reader before any additional
actual key presses are read.
The following options change the way `commandline` updates the
command line buffer:
- `-a` or `--append` do not remove the current commandline, append
the specified string at the end of it
- `-i` or `--insert` do not remove the current commandline, insert
the specified string at the current cursor position
- `-r` or `--replace` remove the current commandline and replace it
with the specified string (default)
The following options change what part of the commandline is printed
or updated:
- `-b` or `--current-buffer` select the entire buffer (default)
- `-j` or `--current-job` select the current job
- `-p` or `--current-process` select the current process
- `-t` or `--current-token` select the current token.
The following options change the way `commandline` prints the current
commandline buffer:
- `-c` or `--cut-at-cursor` only print selection up until the
current cursor position
- `-o` or `--tokenize` tokenize the selection and print one string-type token per line
If `commandline` is called during a call to complete a given string
using `complete -C STRING`, `commandline` will consider the
specified string to be the current contents of the command line.
The following options output metadata about the commandline state:
- `-L` or `--line` print the line that the cursor is on, with the topmost
line starting at 1
- `-S` or `--search-mode` evaluates to true if the commandline is performing
a history search
- `-P` or `--paging-mode` evaluates to true if the commandline is showing
pager contents, such as tab completions
\subsection commandline-example Example
`commandline -j $history[3]` replaces the job under the cursor with the
third item from the command line history.
