DESCRIPTION¶
WARNING: This package is unix-specific and depends on the availability of
two unix system commands for terminal control, i.e.
stty and
tput, both of which have to be found in the
$PATH. If any of
these two commands is missing the loading of the package will fail.
The package provides commands to switch the standard input of the current
process between
raw and
cooked input modes, and to query the
size of terminals, i.e. the available number of columns and lines.
API¶
INTROSPECTION¶
- ::term::ansi::ctrl::unix::import ?ns?
?arg...?
- This command imports some or all attribute commands into
the namespace ns. This is by default the namespace ctrl.
Note that this is relative namespace name, placing the imported command
into a child of the current namespace. By default all commands are
imported, this can howver be restricted by listing the names of the wanted
commands after the namespace argument.
OPERATIONS¶
- ::term::ansi::ctrl::unix::raw
- This command switches the standard input of the current
process to raw input mode. This means that from then on all
characters typed by the user are immediately reported to the application
instead of waiting in the OS buffer until the Enter/Return key is
received.
- ::term::ansi::ctrl::unix::raw
- This command switches the standard input of the current
process to cooked input mode. This means that from then on all
characters typed by the user are kept in OS buffers for editing until the
Enter/Return key is received.
- ::term::ansi::ctrl::unix::columns
- This command queries the terminal connected to the standard
input for the number of columns available for display.
- ::term::ansi::ctrl::unix::rows
- This command queries the terminal connected to the standard
input for the number of rows (aka lines) available for display.
