Implementations§

source§

impl Pty

source

pub fn new_sync( flags: PtyFlags, cancellable: Option<&impl IsA<Cancellable>>, ) -> Result<Pty, Error>

Allocates a new pseudo-terminal.

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

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

If using g_spawn_async() and friends, you MUST either use vte_pty_child_setup() directly as the child setup function, or call vte_pty_child_setup() from your own child setup function supplied.

When using vte_terminal_spawn_sync() with a custom child setup function, vte_pty_child_setup() will be called before the supplied function; you must not call it again.

Also, you MUST pass the [glib::SpawnFlags::DO_NOT_REAP_CHILD][crate::glib::SpawnFlags::DO_NOT_REAP_CHILD] flag.

Note also that [glib::SpawnFlags::STDOUT_TO_DEV_NULL][crate::glib::SpawnFlags::STDOUT_TO_DEV_NULL], [glib::SpawnFlags::STDERR_TO_DEV_NULL][crate::glib::SpawnFlags::STDERR_TO_DEV_NULL], and [glib::SpawnFlags::CHILD_INHERITS_STDIN][crate::glib::SpawnFlags::CHILD_INHERITS_STDIN] are not supported, since stdin, stdout and stderr of the child process will always be connected to the PTY.

Note that you should set the PTY’s size using vte_pty_set_size() before spawning the child process, so that the child process has the correct size from the start instead of starting with a default size and then shortly afterwards receiving a SIGWINCH signal. You should prefer using vte_terminal_pty_new_sync() which does this automatically.

§flags

flags from #VtePtyFlags

§cancellable

a #GCancellable, or None

§Returns

a new #VtePty, or None on error with @error filled in

source

pub fn builder() -> PtyBuilder

Creates a new builder-pattern struct instance to construct Pty objects.

This method returns an instance of PtyBuilder which can be used to create Pty objects.

source

pub fn child_setup(&self)

source

pub fn size(&self) -> Result<(i32, i32), Error>

Reads the pseudo terminal’s window size.

If getting the window size failed, @error will be set to a #GIOError.

§Returns

true on success, false on failure with @error filled in

§rows

a location to store the number of rows, or None

§columns

a location to store the number of columns, or None

source

pub fn set_size(&self, rows: i32, columns: i32) -> Result<(), Error>

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 #GIOError.

§rows

the desired number of rows

§columns

the desired number of columns

§Returns

true on success, false on failure with @error filled in

source

pub fn set_utf8(&self, utf8: bool) -> Result<(), Error>

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.

§utf8

whether or not the pty is in UTF-8 mode

§Returns

true on success, false on failure with @error filled in

source

pub fn flags(&self) -> PtyFlags

Flags.

source§

impl Pty

source

pub fn fd(&self) -> BorrowedFd<'_>

§Returns

the file descriptor of the PTY master in @self. The file descriptor belongs to @self and must not be closed or have its flags changed

source

pub fn foreign_sync( fd: OwnedFd, cancellable: Option<&impl IsA<Cancellable>>, ) -> Result<Pty, Error>

Creates a new #VtePty for the PTY master @fd.

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

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

§fd

a file descriptor to the PTY

§cancellable

a #GCancellable, or None

§Returns

a new #VtePty for @fd, or None on error with @error filled in

source

pub fn spawn_async<P: FnOnce(Result<Pid, Error>) + 'static, Q: Fn() + 'static>( &self, working_directory: Option<&str>, argv: &[&str], envv: &[&str], spawn_flags: SpawnFlags, child_setup: Q, timeout: i32, cancellable: Option<&impl IsA<Cancellable>>, callback: P, )

Like vte_pty_spawn_with_fds_async(), except that this function does not allow passing file descriptors to the child process. See vte_pty_spawn_with_fds_async() for more information.

§working_directory

the name of a directory the command should start in, or None to use the current working directory

§argv

child’s argument vector

§envv

a list of environment variables to be added to the environment before starting the process, or None

§spawn_flags

flags from #GSpawnFlags

§child_setup

an extra child setup function to run in the child just before exec(), or None

§child_setup_data

user data for @child_setup, or None

§child_setup_data_destroy

a #GDestroyNotify for @child_setup_data, or None

§timeout

a timeout value in ms, -1 for the default timeout, or G_MAXINT to wait indefinitely

§cancellable

a #GCancellable, or None

§callback

a #GAsyncReadyCallback, or None

source

pub fn spawn_future<Q: Fn() + 'static>( &self, working_directory: Option<&str>, argv: &[&str], envv: &[&str], spawn_flags: SpawnFlags, child_setup: Q, timeout: i32, ) -> Pin<Box_<dyn Future<Output = Result<Pid, Error>> + 'static>>

source

pub unsafe fn spawn_with_fds_async<P: FnOnce(Result<Pid, Error>) + 'static, Q: Fn() + 'static>( &self, working_directory: Option<&str>, argv: &[&str], envv: &[&str], fds: Vec<OwnedFd>, map_fds: &[RawFd], spawn_flags: SpawnFlags, child_setup: Q, timeout: i32, cancellable: Option<&impl IsA<Cancellable>>, callback: P, )

§Safety

The map_fds have to make sense. Starts the specified command under the pseudo-terminal @self. The @argv and @envv lists should be None-terminated. The “TERM” environment variable is automatically set to a default value, but can be overridden from @envv. @pty_flags controls logging the session to the specified system log files.

Note also that [glib::SpawnFlags::STDOUT_TO_DEV_NULL][crate::glib::SpawnFlags::STDOUT_TO_DEV_NULL], [glib::SpawnFlags::STDERR_TO_DEV_NULL][crate::glib::SpawnFlags::STDERR_TO_DEV_NULL], and [glib::SpawnFlags::CHILD_INHERITS_STDIN][crate::glib::SpawnFlags::CHILD_INHERITS_STDIN] are not supported in @spawn_flags, since stdin, stdout and stderr of the child process will always be connected to the PTY. Also [glib::SpawnFlags::LEAVE_DESCRIPTORS_OPEN][crate::glib::SpawnFlags::LEAVE_DESCRIPTORS_OPEN] is not supported; and [glib::SpawnFlags::DO_NOT_REAP_CHILD][crate::glib::SpawnFlags::DO_NOT_REAP_CHILD] will always be added to @spawn_flags.

If @fds is not None, the child process will map the file descriptors from @fds according to @map_fds; @n_map_fds must be less or equal to @n_fds. This function will take ownership of the file descriptors in @fds; you must not use or close them after this call. All file descriptors in @fds must have the FD_CLOEXEC flag set on them; it will be unset in the child process before calling man:execve(2). Note also that no file descriptor may be mapped to stdin, stdout, or stderr (file descriptors 0, 1, or 2), since these will be assigned to the PTY. All open file descriptors apart from those mapped as above will be closed when execve() is called.

Beginning with 0.60, and on linux only, and unless VTE_SPAWN_NO_SYSTEMD_SCOPE is passed in @spawn_flags, the newly created child process will be moved to its own systemd user scope; and if VTE_SPAWN_REQUIRE_SYSTEMD_SCOPE is passed, and creation of the systemd user scope fails, the whole spawn will fail. You can override the options used for the systemd user scope by providing a systemd override file for ‘vte-spawn-.scope’ unit. See man:systemd.unit(5) for further information.

See vte_pty_new(), and vte_terminal_watch_child() for more information.
