If i3-msg is invoked with -t subscribe, it will wait for the first event
matching the given payload, before exiting.
For instance, get the number of the next focused workspace with:
i3-msg -t subscribe '[ "workspace" ]' | jshon -e current -e num
Like inotifywait, the -m flag allows to wait indefinitely for events,
instead of exiting right after receiving the first one.
For example, continuously monitor the names of focused windows with:
i3-msg -t subscribe -m '[ "window" ]' | jq .container.name
i3-msg currently exits right after sending the IPC message if the quiet
flag is set. This means that if an error occurred when issuing a
command, e.g. "i3-msg -q foobar", it gets silently ignored.
What we really want is to just skip printing but still check the reply.
At the same time, explicitly print the reply when we need to, instead of
using an exit label.
Before:
$ i3-msg floating disable, move window to position 100 px 100 px
ERROR: Your command: (null)
ERROR: (null)
ERROR: Cannot change position of a window/container because it is not floating.
[{"success":true},{"success":false,"error":"Cannot change position of a window/container because it is not floating."}]
After:
$ i3-msg floating disable, move window to position 100 px 100 px
ERROR: Cannot change position of a window/container because it is not floating.
[{"success":true},{"success":false,"error":"Cannot change position of a window/container because it is not floating."}]
All other message types are verbs, only our first-ever message COMMAND wasn’t.
While we’re here, also change the message type dictionary into a table with
clickable links to the corresponding reply type.
Authors of downstream IPC libraries are encouraged to keep the old name around
so as to not break existing code, but mark it as deprecated.
This introduces memory usage by one copy of the config file, which is an
acceptable trade-off for being able to easily revert data loss.
The default config is 6KB, user configs will be in the same ballpark.
fixes#2856
If getopt() returns '?' (option with a missing argument), exit the program with an error code rather than continuing the execution.
Fix the issue #2804 (https://github.com/i3/i3/issues/2804).
Including config.h is necessary to get e.g. the _GNU_SOURCE define and
any other definitions that autoconf declares. Hence, config.h needs to
be included as the first header in each file.
This is done either via:
1. Including "common.h" (i3bar)
2. Including "libi3.h"
3. Including "all.h" (i3)
4. Including <config.h> directly
Also remove now-unused I3__FILE__, add copyright/license statement
where missing and switch include/all.h to #pragma once.
pledges for i3:
"stdio rpath unix" for talking to the i3 socket usually in /tmp
"proc exec" for executing programs
"wpath cpath" are needed for the restart-in-place functionality
To make this work, @semarie pointed out that it is sufficient to ensure
that we get physical_mem_bytes only once, namely in init_logging().
pledges for i3-msg:
"stdio rpath unix" are needed for talking to the i3-socket
pledges for i3-nagbar
"rpath getpw" to find the home directory
"wpath cpath" to write the script
"proc exec" to execute the script
This has multiple effects:
1) The i3 codebase is now consistently formatted. clang-format uncovered
plenty of places where inconsistent code made it into our code base.
2) When writing code, you don’t need to think or worry about our coding
style. Write it in yours, then run clang-format-3.5
3) When submitting patches, we don’t need to argue about coding style.
The basic idea is that we don’t want to care about _how_ we write the
code, but _what_ it does :). The coding style that we use is defined in
the .clang-format config file and is based on the google style, but
adapted in such a way that the number of modifications to the i3 code
base is minimal.
This removes code duplication, which will be useful for a subsequent
commit.
Furthermore, we now don’t open X11 connections unnecessarily in some
corner cases.
This is useful for third-party scripts which require certain features
and want to error out cleanly when they are run with an old i3 version.
Additionally, i3 --version might be different from what’s actually
running (an old version of the binary), so i3-msg -t get_version will be
the best way to figure out the i3 version you are actually running from
this commit on.
