# Changelog
### master
- bugfix: "auto restore" feature stopped working
- bugfix: prevent race condition when auto-saving with locks (@v9v)
- Multiple users on a system can now each run continuum on their own.
### v3.1.0, 2015-03-14
- properly quote scripts
- bugfix: "auto restore" feature does not work on tmux `1.9a`
- bugfix: do not count `tmux source-file .tmux.conf` as a tmux process (when
checking if other tmux server is running). Previously, this caused
interpolation command not to be inserted into `status-right` because `tmux
source-file` was falsely detected as another tmux server.
- add `#{continuum_status}` status line interpolation
### v3.0.0, 2015-02-20
- rename the plugin from `tmux-resurrect-auto` to `tmux-continuum`
### v2.2.0, 2015-02-20
- document tmux multi-server behavior in the readme
- do not auto-restore tmux environment if another tmux server is already running
(we don't want to duplicate stuff)
- bugfixes for 'tmux auto start' OS X Terminal.app and iTerm scripts
- prevent saving for the first 15 minutes only when plugin is sourced the first
time (not on subsequent sources or tmux.conf reloads)
- do not start auto-saving if there's another tmux server running (we don't want
for save files from various tmux environments to override each other)
### v2.1.0, 2015-02-18
- enable "tmux auto start" for OS X
- enable customizing "tmux auto start" for OS X
- fix errors when creating a launchd plist file for auto-start on OS X
### v2.0.0, 2015-02-15
- enable automatic environment restore when tmux is started
### v1.0.0, 2015-02-12
- first working version
- run the save script in the background
- do not start saving right after tmux is started
- add a check for tmux version to the initializer script
- when interval is set to '0' autosave is disabled
- bugfix: helper files not loaded
- update readme with the instructions how to disable auto saving

# tmux-continuum
Features:
- continuous saving of tmux environment
- automatic tmux start when computer/server is turned on
- automatic restore when tmux is started
Together, these features enable uninterrupted tmux usage. No matter the computer
or server restarts, if the machine is on, tmux will be there how you left it off
the last time it was used.
Tested and working on Linux, OSX and Cygwin.
#### Continuous saving
Tmux environment will be saved at an interval of 15 minutes. All the saving
happens in the background without impact to your workflow.
This action starts automatically when the plugin is installed. Note it requires
the status line to be `on` to run (since it uses a hook in status-right to run).
#### Automatic tmux start
Tmux is automatically started after the computer/server is turned on.
See the [instructions](docs/automatic_start.md) on how to enable this for your
system.
#### Automatic restore
Last saved environment is automatically restored when tmux is started.
Put `set -g @continuum-restore 'on'` in `.tmux.conf` to enable this.
Note: automatic restore happens **exclusively** on tmux server start. No other
action (e.g. sourcing `.tmux.conf`) triggers this.
#### Dependencies
`tmux 1.9` or higher, `bash`,
[tmux-resurrect](https://github.com/tmux-plugins/tmux-resurrect) plugin.
### Installation with [Tmux Plugin Manager](https://github.com/tmux-plugins/tpm) (recommended)
Please make sure you have
[tmux-resurrect](https://github.com/tmux-plugins/tmux-resurrect) installed.
Add plugin to the list of TPM plugins in `.tmux.conf`:
set -g @plugin 'tmux-plugins/tmux-resurrect'
set -g @plugin 'tmux-plugins/tmux-continuum'
Hit `prefix + I` to fetch the plugin and source it. The plugin will
automatically start "working" in the background, no action required.
### Manual Installation
Please make sure you have
[tmux-resurrect](https://github.com/tmux-plugins/tmux-resurrect) installed.
Clone the repo:
$ git clone https://github.com/tmux-plugins/tmux-continuum ~/clone/path
Add this line to the bottom of `.tmux.conf`:
run-shell ~/clone/path/continuum.tmux
Reload TMUX environment with: `$ tmux source-file ~/.tmux.conf`
The plugin will automatically start "working" in the background, no action
required.
### Docs
- [frequently asked questions](docs/faq.md)
- [behavior when running multiple tmux servers](docs/multiple_tmux_servers.md) -
this doc is safe to skip, but you might want to read it if you're using tmux
with `-L` or `-S` flags
- [automatically start tmux after the computer is turned on](docs/automatic_start.md)
- [continuum status in tmux status line](docs/continuum_status.md)
### Other goodies
- [tmux-copycat](https://github.com/tmux-plugins/tmux-copycat) - a plugin for
regex searches in tmux and fast match selection
- [tmux-yank](https://github.com/tmux-plugins/tmux-yank) - enables copying
highlighted text to system clipboard
- [tmux-open](https://github.com/tmux-plugins/tmux-open) - a plugin for quickly
opening highlighted file or a url
### Known Issues
- In order to be executed periodically, the plugin updates the `status-right` tmux variable. In case some plugin (usually themes) overwrites the `status-right` variable, the autosave feature stops working. To fix this issue, place the plugin last in the TPM plugins list.

# Automatic Tmux start
Tmux is automatically started after the computer/server is turned on.
### OS X
To enable this feature:
- put `set -g @continuum-boot 'on'` in `.tmux.conf`
- reload tmux config with this shell command: `$ tmux source-file ~/.tmux.conf`
Next time the computer is started:
- `Terminal.app` window will open and resize to maximum size
- `tmux` command will be executed in the terminal window
- if "auto restore" feature is enabled, tmux will start restoring previous env
Config options:
- `set -g @continuum-boot-options 'fullscreen'` - terminal window
will go fullscreen
- `set -g @continuum-boot-options 'iterm'` - start [iTerm](https://www.iterm2.com) instead
of `Terminal.app`
- `set -g @continuum-boot-options 'iterm,fullscreen'` - start `iTerm`
in fullscreen
- `set -g @continuum-boot-options 'kitty'` - start [kitty](https://sw.kovidgoyal.net/kitty) instead
of `Terminal.app`
- `set -g @continuum-boot-options 'kitty,fullscreen'` - start `kitty`
in fullscreen
- `set -g @continuum-boot-options 'alacritty'` - start [alacritty](https://github.com/alacritty/alacritty) instead of `Terminal.app`
- `set -g @continuum-boot-options 'alacritty,fullscreen'` - start `alacritty`
in fullscreen
Note: The first time you reboot your machine and activate this feature you may be prompted about a script requiring
access to a system program (i.e. - System Events). If this happens tmux will not start automatically and you will need
to go to `System Preferences -> Security & Privacy -> Accessability` and add the script to the list of apps that are
allowed to control your computer.
### Linux
Help with this would be greatly appreciated. Please get in touch.
#### Systemd
##### this will only start the tmux server, it will *not* start any terminal emulator
To enable automatic start with systemd:
- Put `set -g @continuum-boot 'on'` in `.tmux.conf`
- reload tmux config with this shell command: `$ tmux source-file ~/.tmux.conf`
- see [systemd](/docs/systemd_details.md) for more details about how this is implemented

## Continuum status in tmux status line
There is an option to display current status of tmux continuum in tmux status
line. This is done via `#{continuum_status}` interpolation and it works with
both `status-right` and `status-left` tmux native options.
Example usage:
set -g status-right 'Continuum status: #{continuum_status}'
When running, `#{continuum_status}` will show continuum save interval:
Continuum status: 15
or if continuous saving is disabled:
Continuum status: off

### FAQ
> Will a previous save be overwritten immediately after I start tmux?
No, first automatic save starts 15 minutes after tmux is started. If automatic
restore is not enabled, that gives you enough time to manually restore from a
previous save.
> I want to make a restore to a previous point in time, but it seems that save
is now overwritten?
Read how to [restore a previously saved environment](https://github.com/tmux-plugins/tmux-resurrect/blob/master/docs/restoring_previously_saved_environment.md)
> Will this plugin fill my hard disk?
Most likely no. A regular save file is in the range of 5Kb. And `tmux-resurrect` already has a `remove_old_backups()` routine that will ["remove resurrect files older than 30 days, but keep at least 5 copies of backup."](https://github.com/tmux-plugins/tmux-resurrect/blob/da1a7558024b8552f7262b39ed22e3d679304f99/scripts/save.sh#L271-L277)
> How do I change the save interval to i.e. 1 hour?
The interval is always measured in minutes. So setting the interval to `60`
(minutes) will do the trick. Put this in `.tmux.conf`:
set -g @continuum-save-interval '60'
and then source `tmux.conf` by executing this command in the shell
`$ tmux source-file ~/.tmux.conf`.
> How do I stop automatic saving?
Just set the save interval to `0`. Put this in `.tmux.conf`
set -g @continuum-save-interval '0'
and then source `tmux.conf` by executing this command in the shell
`$ tmux source-file ~/.tmux.conf`.
> I had automatic restore turned on, how do I disable it now?
Just remove `set -g @continuum-restore 'on'` from `tmux.conf`.
To be absolutely sure automatic restore doesn't happen, create a
`tmux_no_auto_restore` file in your home directory (command:
`$ touch ~/tmux_no_auto_restore`). Automatic restore won't happen if this file
exists.

### Behavior when running multiple tmux servers
(This is safe to skip if you're always running a single tmux server.)
If you're an advanced tmux user, you might be running multiple tmux servers at
the same time. Maybe you start the first tmux server with `$ tmux` and then
later another one with e.g. `$ tmux -S/tmp/foo`.
You probably don't want to "auto restore" the same environment in the second
tmux that uses `/tmp/foo` socket. You also probably don't want two tmux
environments both having "auto save" feature on (think about overwrites).
This plugin handles multi-server scenario by giving precedence to the tmux
server that was first started.
In the above example, the server started with `$ tmux` will do "auto
restore" (if enabled) and will start "auto saving".
"Auto restore" or "auto saving" **will not** happen for the second server that
was started later with the `$ tmux -S/tmp/foo` command. The plugin will
detect the presence of another server (`$ tmux`) and give it precedence.

# Systemd automatic start for tmux
The first time tmux starts when `@continuum-boot` is set to 'on' tmux-continuum will generate a user level systemd unit file which it will save to `${HOME}/.config/systemd/user/tmux.service` and enable it. From then on when that user logs in, either through a GUI session or on the console or via ssh, Systemd will start the tmux server.
The command used to start the tmux server is determined via the `@continuum-systemd-start-cmd` option that can be set in .tmux.conf. (Remember to reload your configuration with `tmux source ~/.tmux.conf` afterwards.
The default command to use is `new-session -d`. If you want more control over what sessions get started then you should set up your sessions in tmux.conf and set `@continuum-systemd-start-cmd = 'start-server'`. As this will be executed as part of systemd's ExecStart statement there will be no shell parsing. See [Systemd manual](http://www.freedesktop.org/software/systemd/man/systemd.service.html#Command%20lines) for more details.
To control the tmux service you can use all the standard `systemctl` commands using the `--user` argument. eg to see if the tmux server has started:
systemctl --user status tmux.service

This sample hook safeguards topic branches that have been
published from being rewound.
The workflow assumed here is:
* Once a topic branch forks from "master", "master" is never
merged into it again (either directly or indirectly).
* Once a topic branch is fully cooked and merged into "master",
it is deleted. If you need to build on top of it to correct
earlier mistakes, a new topic branch is created by forking at
the tip of the "master". This is not strictly necessary, but
it makes it easier to keep your history simple.
* Whenever you need to test or publish your changes to topic
branches, merge them into "next" branch.
The script, being an example, hardcodes the publish branch name
to be "next", but it is trivial to make it configurable via
$GIT_DIR/config mechanism.
With this workflow, you would want to know:
(1) ... if a topic branch has ever been merged to "next". Young
topic branches can have stupid mistakes you would rather
clean up before publishing, and things that have not been
merged into other branches can be easily rebased without
affecting other people. But once it is published, you would
not want to rewind it.
(2) ... if a topic branch has been fully merged to "master".
Then you can delete it. More importantly, you should not
build on top of it -- other people may already want to
change things related to the topic as patches against your
"master", so if you need further changes, it is better to
fork the topic (perhaps with the same name) afresh from the
tip of "master".
Let's look at this example:
o---o---o---o---o---o---o---o---o---o "next"
/ / / /
/ a---a---b A / /
/ / / /
/ / c---c---c---c B /
/ / / \ /
/ / / b---b C \ /
/ / / / \ /
---o---o---o---o---o---o---o---o---o---o---o "master"
A, B and C are topic branches.
* A has one fix since it was merged up to "next".
* B has finished. It has been fully merged up to "master" and "next",
and is ready to be deleted.
* C has not merged to "next" at all.
We would want to allow C to be rebased, refuse A, and encourage
B to be deleted.
To compute (1):
git rev-list ^master ^topic next
git rev-list ^master next
if these match, topic has not merged in next at all.
To compute (2):
git rev-list master..topic
if this is empty, it is fully merged to "master".

# An example hook script to update a checked-out tree on a git push.
#
# This hook is invoked by git-receive-pack(1) when it reacts to git
# push and updates reference(s) in its repository, and when the push
# tries to update the branch that is currently checked out and the
# receive.denyCurrentBranch configuration variable is set to
# updateInstead.
#
# By default, such a push is refused if the working tree and the index
# of the remote repository has any difference from the currently
# checked out commit; when both the working tree and the index match
# the current commit, they are updated to match the newly pushed tip
# of the branch. This hook is to be used to override the default
# behaviour; however the code below reimplements the default behaviour
# as a starting point for convenient modification.
#
# The hook receives the commit with which the tip of the current
# branch is going to be updated:
commit=$1
# It can exit with a non-zero status to refuse the push (when it does
# so, it must not modify the index or the working tree).
die () {
echo >&2 "$*"
exit 1
}
# Or it can make any necessary changes to the working tree and to the
# index to bring them to the desired state when the tip of the current
# branch is updated to the new commit, and exit with a zero status.
#
# For example, the hook can simply run git read-tree -u -m HEAD "$1"
# in order to emulate git fetch that is run in the reverse direction
# with git push, as the two-tree form of git read-tree -u -m is
# essentially the same as git switch or git checkout that switches
# branches while keeping the local changes in the working tree that do
# not interfere with the difference between the branches.
# The below is a more-or-less exact translation to shell of the C code
# for the default behaviour for git's push-to-checkout hook defined in
# the push_to_deploy() function in builtin/receive-pack.c.
#
# Note that the hook will be executed from the repository directory,
# not from the working tree, so if you want to perform operations on
# the working tree, you will have to adapt your code accordingly, e.g.
# by adding "cd .." or using relative paths.

============
Contributing
============
Want to improve the quality of tmux-mem-cpu-load code? Great! Here's a quick
guide:
1. Fork, then clone the repo:
git clone git@github.com:your-username/tmux-mem-cpu-load
2. Make your change. Add tests for your change.
3. See if it compiles and runs like it should.
4. Run tests to check if you didn't break anything:
make test
Push to your fork and `submit a pull request`_.
At this point you're waiting on us. We'll review your changes as soon as we can.
Before merging your changes we may request you to make some changes or
corrections.
Style guidelines
----------------
You'll need to follow the subsequent rules in order to get your code merged:
* Use Allman_ style for block braces.
* No space before `(`
* Add space after each `(` and before each `)`
* Use braces single line statements
* Don't use mixed case naming style, use underscores instead.
Bad example:
int myAwesomeVariable = 0;
doSomething( myAwesomeVariable );
Good example:
int my_awesome_variable = 0;
do_something( my_awesome_variable );
* Don't vertically align tokens on consecutive lines.
* If you break up an argument list, align the line to opening brace
* Use 2 space indentation (no tabs)
* Use spaces around operators, except for unary operators, such as `!`.
* Add LICENSE header in new files you create.
* Put vim modeline as the first line of file header
* Use the lower-case for CMake commands
* Do not add trailing whitespace
You can use this bash script to strip unnecessary whitespaces:

tmux-mem-cpu-load
=============================================
---------------------------------------------
CPU, RAM, and load monitor for use with tmux_
---------------------------------------------
.. image:: https://circleci.com/gh/thewtex/tmux-mem-cpu-load.svg?style=svg
:target: https://circleci.com/gh/thewtex/tmux-mem-cpu-load
.. image:: https://github.com/thewtex/tmux-mem-cpu-load/actions/workflows/main.yml/badge.svg
:target: https://github.com/thewtex/tmux-mem-cpu-load/actions/workflows/main.yml
Description
===========
A simple, lightweight program provided for system monitoring in the *status*
line of **tmux**.
The memory monitor displays the used and available memory.
The CPU usage monitor outputs a percent CPU usage over all processors. It also
displays a textual bar graph of the current percent usage.
The system load average is also displayed.
Example output::
2885/7987MB [||||| ] 51.2% 2.11 2.35 2.44
^ ^ ^ ^ ^ ^ ^
| | | | | | |
1 2 3 4 5 6 7
1. Currently used memory.
2. Available memory.
3. CPU usage bar graph.
4. CPU usage percentage.
5. Load average for the past minute.
6. Load average for the past 5 minutes.
7. Load average for the past 15 minutes.
For `terminals with 256 color support`_, graded colors can be displayed by
passing the **--colors** flag.
Installation
============
Dependencies
------------
Currently, Linux, Mac OSX, FreeBSD, OpenBSD, and NetBSD are supported.
Building
~~~~~~~~
* >= CMake_ -3.5
* C++ compiler with C++11 support (e.g. gcc/g++ >= 4.6)
Download
--------
There are links to the source code at the `project homepage`_.
Build
-----
::
cd <source dir>
cmake .
make
Install
-------
::
su -
make install
logout
Build and Install Using tpm_
-----------------------------
Include the plugin in your ``.tmux.conf``, the same file you'll set the
configuration in, below.
::
set -g @plugin 'thewtex/tmux-mem-cpu-load'
Install with Package Managers
-----------------------------
* Gentoo: ``emerge tmux-mem-cpu-load``
* Homebrew: ``brew install tmux-mem-cpu-load``
Build and Install Using Antigen_
--------------------------------
Include the bundle in your ``.zshrc``
::
antigen bundle thewtex/tmux-mem-cpu-load
Configuring tmux_
=================
Edit ``$HOME/.tmux.conf`` to display the program's output in *status-left* or
*status-right*. For example::
set -g status-interval 2
set -g status-left "#S #[fg=green,bg=black]#(tmux-mem-cpu-load --colors --interval 2)#[default]"
set -g status-left-length 60
If you installed using tpm, you must specify the full path to the
``tmux-mem-cpu-load`` script, like below::
set -g status-right "#[fg=green]#($TMUX_PLUGIN_MANAGER_PATH/tmux-mem-cpu-load/tmux-mem-cpu-load --colors --powerline-right --interval 2)#[default]"
Note that the *interval* argument to `tmux-mem-cpu-load` should be the same number
of seconds that *status-interval* is set at.
Another optional argument is the number of bars in the bar graph, which
defaults to 10. This can, for instance, be set to the number of cores in a
multi-core system.
The *colors* option will add graded colors for each of the measures.
The full usage::
Usage: tmux-mem-cpu-load [OPTIONS]
Available options:
-h, --help
Prints this help message
-c, --colors
Use tmux colors in output
-p, --powerline-left
Use powerline left symbols throughout the output, enables --colors
-q, --powerline-right
Use powerline right symbols throughout the output, enables --colors
-v, --vertical-graph
Use vertical bar chart for CPU graph
-l <value>, --segments-left <value>
Enable blending bg/fg color (depending on -p or -q use) with segment to left
Provide color to be used depending on -p or -q option for seamless segment blending
Color is an integer value which uses the standard tmux color palette values
-r <value>, --segments-right <value>
Enable blending bg/fg color (depending on -p or -q use) with segment to right
Provide color to be used depending on -p or -q option for seamless segment blending
Color is an integer value which uses the standard tmux color palette values
-i <value>, --interval <value>
Set tmux status refresh interval in seconds. Default: 1 second
-g <value>, --graph-lines <value>
Set how many lines should be drawn in a graph. Default: 10
-m <value>, --mem-mode <value>
Set memory display mode. 0: Default, 1: Free memory, 2: Usage percent.
-t <value>, --cpu-mode <value>
Set cpu % display mode. 0: Default max 100%, 1: Max 100% * number of threads.
-a <value>, --averages-count <value>
Set how many load-averages should be drawn. Default: 3
Blending Dynamic Colors Tmux Powerline Segments
===============================================
The -l and -r options when used in conjunction with a recent version of Tmux Powerline
that has the ability to selectively disable spacing and separators between segments allow
for seamless blending of tmux-mem-cpu-load output with other adjacent segments. The end
result is dynamic changing of appropriate foreground and background colors as the start
and end of the tmux-mem-cpu-load output string that is aggregated with other Tmux
Powerline output to produce a more polished status line in Tmux.
Segment Adjaceny before this feature:
.. image:: seg-adj1.png
Segment Adjaceny after this feature:
.. image:: seg-adj2.png
Note that the values for the -l and -r options will be the standard Tmux integer color
values. They set the appropriate background and foreground colors used for the separator
character when used with the poweline-left or powerline-right options so it is easy to
match coloring to adjacent segments. An example from the segment script that calls
tmux-mem-cpu-load is as follows::
tmux-mem-cpu-load -q -v -l 52 -r 33
This combines with theme options available to tmux-powerline, such as the following::
"disk_usage_cust 52 123 ${TMUX_POWERLINE_SEPARATOR_LEFT_BOLD} 52 123 right_disable" \
"tmux_mem_cpu_load_cust 52 234 ${TMUX_POWERLINE_SEPARATOR_LEFT_BOLD} 52 234 both_disable separator_disable" \
"batt_cust 33 154 ${TMUX_POWERLINE_SEPARATOR_LEFT_BOLD} 16 33 N separator_disable" \
