Methods

gobjectType :: Pty -> IO GType

IsInitable Pty

Defined in GI.Vte.Objects.Pty

IsObject Pty

Defined in GI.Vte.Objects.Pty

IsPty Pty

Defined in GI.Vte.Objects.Pty

class GObject o => IsPty o

Type class for types which can be safely cast to Pty, for instance with toPty.

Instances

(GObject a, (UnknownAncestorError Pty a :: Constraint)) => IsPty a

Defined in GI.Vte.Objects.Pty

IsPty Pty

Defined in GI.Vte.Objects.Pty

toPty :: (MonadIO m, IsPty o) => o -> m Pty

Cast to Pty, for types for which this is known to be safe. For general casts, use castTo.

noPty :: Maybe Pty

A convenience alias for Nothing :: Maybe Pty.

Methods

childSetup

ptyChildSetup

Arguments

:: (HasCallStack, MonadIO m, IsPty a)

=> a

pty: a Pty

-> m ()

FIXMEchpe

close

ptyClose

Arguments

:: (HasCallStack, MonadIO m, IsPty a)

=> a

pty: a Pty

-> m ()

Deprecated: (Since version 0.42)

Since 0.42 this is a no-op.

getFd

ptyGetFd

Arguments

:: (HasCallStack, MonadIO m, IsPty a)

=> a

pty: a Pty

-> m Int32

Returns: the file descriptor of the PTY master in pty. The file descriptor belongs to pty and must not be closed

No description available in the introspection data.

getSize

ptyGetSize

Arguments

:: (HasCallStack, MonadIO m, IsPty a)

=> a

pty: a Pty

-> m (Int32, Int32)

(Can throw GError)

Reads the pseudo terminal's window size.

If getting the window size failed, error will be set to a IOError.

newForeignSync

ptyNewForeignSync

Arguments

:: (HasCallStack, MonadIO m, IsCancellable a)

=> Int32

fd: a file descriptor to the PTY

-> Maybe a

cancellable: a Cancellable, or Nothing

-> m Pty

Returns: a new Pty for fd, or Nothing on error with error filled in (Can throw GError)

Creates a new Pty for the PTY master fd.

No entry will be made in the lastlog, utmp or wtmp system files.

Note that the newly created Pty will take ownership of fd and close it on finalize.

newSync

ptyNewSync

Arguments

:: (HasCallStack, MonadIO m, IsCancellable a)

=> [PtyFlags]

flags: flags from PtyFlags

-> Maybe a

cancellable: a Cancellable, or Nothing

-> m Pty

Returns: a new Pty, or Nothing on error with error filled in (Can throw GError)

Allocates a new pseudo-terminal.

You can later use fork() or the spawnAsync family of functions to start a process on the PTY.

If using fork(), you MUST call ptyChildSetup in the child.

If using spawnAsync and friends, you MUST either use ptyChildSetup directly as the child setup function, or call ptyChildSetup from your own child setup function supplied.

When using terminalSpawnSync with a custom child setup function, ptyChildSetup will be called before the supplied function; you must not call it again.

Also, you MUST pass the SpawnFlagsDoNotReapChild flag.

setSize

ptySetSize

Arguments

:: (HasCallStack, MonadIO m, IsPty a)

=> a

pty: a Pty

-> Int32

rows: the desired number of rows

-> Int32

columns: the desired number of columns

-> m ()

(Can throw GError)

Attempts to resize the pseudo terminal's window size. If successful, the OS kernel will send SIGWINCH to the child process group.

If setting the window size failed, error will be set to a IOError.

setUtf8

ptySetUtf8

Arguments

:: (HasCallStack, MonadIO m, IsPty a)

=> a

pty: a Pty

-> Bool

utf8: whether or not the pty is in UTF-8 mode

-> m ()

(Can throw GError)

Tells the kernel whether the terminal is UTF-8 or not, in case it can make use of the info. Linux 2.6.5 or so defines IUTF8 to make the line discipline do multibyte backspace correctly.

spawnFinish

ptySpawnFinish

Arguments

:: (HasCallStack, MonadIO m, IsPty a, IsAsyncResult b)

=> a

pty: a Pty

-> b

result: a AsyncResult

-> m Int32

(Can throw GError)

Properties

fd

The file descriptor of the PTY master.

constructPtyFd :: IsPty o => Int32 -> IO (GValueConstruct o)

Construct a GValueConstruct with valid value for the “fd” property. This is rarely needed directly, but it is used by new.

getPtyFd :: (MonadIO m, IsPty o) => o -> m Int32

Get the value of the “fd” property. When overloading is enabled, this is equivalent to

get pty #fd

flags

Flags.

constructPtyFlags :: IsPty o => [PtyFlags] -> IO (GValueConstruct o)

Construct a GValueConstruct with valid value for the “flags” property. This is rarely needed directly, but it is used by new.

getPtyFlags :: (MonadIO m, IsPty o) => o -> m [PtyFlags]

Get the value of the “flags” property. When overloading is enabled, this is equivalent to

get pty #flags
