From 13310ee7dce177a24252970f607c08f3d658e676 Mon Sep 17 00:00:00 2001 From: Matias Linares Date: Sun, 22 Nov 2015 04:02:19 -0300 Subject: Add socket functionality. Something simple, but it works pretty well. The mapping between the strings that comes from the socket and functions, modifiers, keys, etc. needs some rewrite because now there's a manual mapping. The autostart file shows some functionality on how it will work. Since the next_xevent is ticking on 1s, it's preferible to make the writes on the socket all together, otherwise will pass 1 sec between two calls. --- Cargo.lock | 6 +++++ Cargo.toml | 1 + autostart | 10 ++++++-- src/main.rs | 27 +++++++++++--------- src/safe_x11/event.rs | 2 +- src/socket.rs | 63 ---------------------------------------------- src/socket/mod.rs | 31 +++++++++++++++++++++++ src/socket/parser.rs | 70 +++++++++++++++++++++++++++++++++++++++++++++++++++ 8 files changed, 132 insertions(+), 78 deletions(-) delete mode 100644 src/socket.rs create mode 100644 src/socket/mod.rs create mode 100644 src/socket/parser.rs diff --git a/Cargo.lock b/Cargo.lock index eabeb47..646922b 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -3,6 +3,7 @@ name = "dotwm" version = "0.1.0" dependencies = [ "libc 0.2.2 (registry+https://github.com/rust-lang/crates.io-index)", + "nom 1.0.0 (registry+https://github.com/rust-lang/crates.io-index)", "unix_socket 0.5.0 (registry+https://github.com/rust-lang/crates.io-index)", "x11 2.2.1 (registry+https://github.com/rust-lang/crates.io-index)", ] @@ -22,6 +23,11 @@ name = "libc" version = "0.2.2" source = "registry+https://github.com/rust-lang/crates.io-index" +[[package]] +name = "nom" +version = "1.0.0" +source = "registry+https://github.com/rust-lang/crates.io-index" + [[package]] name = "pkg-config" version = "0.3.6" diff --git a/Cargo.toml b/Cargo.toml index 66e2b19..d3f709f 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -6,6 +6,7 @@ authors = ["Matias Linares "] [dependencies] libc = "0.2.*" unix_socket = "*" +nom = "*" [dependencies.x11] version = "*" diff --git a/autostart b/autostart index 82cc3f6..1e98405 100755 --- a/autostart +++ b/autostart @@ -1,4 +1,10 @@ #!/bin/mksh -echo -n "hola" | netcat -U ./dotwm.sock -echo -n "done" | netcat -U ./dotwm.sock +netcat -U dotwm.sock < c_int { pub fn next_xevent(display: *mut Display, fd: c_int) -> XEvent { unsafe { let mut last_event: XEvent = uninitialized(); - let retval = select_next_event(display, fd, &mut last_event) as i32; + select_next_event(display, fd, &mut last_event) as i32; last_event } } diff --git a/src/socket.rs b/src/socket.rs deleted file mode 100644 index b3bb9cc..0000000 --- a/src/socket.rs +++ /dev/null @@ -1,63 +0,0 @@ -// See LICENSE file for copyright and license details. - -use std::io::{Read,Write}; -use std::sync::mpsc::{Receiver, TryRecvError}; - -use unix_socket::UnixStream; - -use dotwm::DotWM; -use command::*; - -#[allow(unused_variables)] -fn handle_socket(dotwm: &mut DotWM, stream: UnixStream) { - let mut s = stream.try_clone().unwrap(); - let mut buf = String::new(); - s.read_to_string(&mut buf).unwrap(); - println!("buf: {}", buf); - - let _ = write!(s, "ok"); -} - -#[allow(unused_variables)] -/// Handles the configuration and returns true when we're finished. -fn handle_configure(dotwm: &mut DotWM, s: UnixStream) -> bool { - let mut stream = match s.try_clone() { - Ok(s) => s, - Err(_) => { println!("Error"); return true }, - }; - - let mut input = String::new(); - stream.read_to_string(&mut input).unwrap(); - - if input != "done" { - let _ = write!(stream, "ok"); - false - } else { - let _ = write!(stream, "exit"); - true - } -} - -pub fn configure_wm(dotwm: &mut DotWM, rx: &Receiver) { - exec_cmd("./autostart", &[]).unwrap(); - loop { - match rx.recv() { - Ok(stream) => { - if handle_configure(dotwm, stream) { - break; - } - }, - Err(e) => panic!("Socket: {}", e), - } - } -} - -pub fn listen_socket(dotwm: &mut DotWM, rx: &Receiver) { - loop { - match rx.try_recv() { - Ok(stream) => handle_socket(dotwm, stream) , - Err(TryRecvError::Empty) => break, - Err(TryRecvError::Disconnected) => panic!("Socket disconnected"), - } - } -} diff --git a/src/socket/mod.rs b/src/socket/mod.rs new file mode 100644 index 0000000..804f7ac --- /dev/null +++ b/src/socket/mod.rs @@ -0,0 +1,31 @@ +// See LICENSE file for copyright and license details. + +pub mod parser; + +use std::io::{Read,Write}; +use std::sync::mpsc::{Receiver, TryRecvError}; + +use unix_socket::UnixStream; + +use dotwm::DotWM; +use command::*; + +/// Listen a socket parsing and executing all the commands. +pub fn listen_socket(dotwm: &mut DotWM, bindings: &mut BindingHash, rx: &Receiver) { + loop { + match rx.try_recv() { + Ok(stream) => { + let mut s = stream.try_clone().unwrap(); + let mut buf = String::new(); + s.read_to_string(&mut buf).unwrap(); + + for line in buf.lines() { + let result = parser::parse(dotwm, bindings, &line); + let _ = write!(s, "{}", result); + } + }, + Err(TryRecvError::Empty) => break, + Err(TryRecvError::Disconnected) => panic!("Socket disconnected"), + } + } +} diff --git a/src/socket/parser.rs b/src/socket/parser.rs new file mode 100644 index 0000000..3cfc15d --- /dev/null +++ b/src/socket/parser.rs @@ -0,0 +1,70 @@ +// See LICENSE file for copyright and license details. + +//!
