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::cooked
- 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.
