# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, sex characteristics, gender identity and expression,
level of experience, education, socio-economic status, nationality, personal
appearance, race, religion, or sexual identity and orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at admin@qvantnet.com. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,

# Contributing guidelines
## When submitting pull requests
* Explain your thinking in why a change or addition is needed.
* Is it a requested change or feature?
* If not, open a feature request to get feedback before making a pull request.
* Split up multiple unrelated changes in multiple pull requests.
* If it's a fix for a unreported bug, make a bug report and link the pull request.
* Purely cosmetic changes won't be accepted without a very good explanation of its value.
## Formatting
### Follow the current syntax design
* Indent type: Tabs
* Tab size: 4
## Optimization
* Avoid writing to disk if possible.
* Make sure variables/vectors/maps/classes etc. are cleaned up if not reused.
* Compare cpu and memory usage with and without your code and look for alternatives if they cause a noticeable negative impact.
For questions contact Aristocratos at admin@qvantnet.com
For proposing changes to this document create a [new issue](https://github.com/aristocratos/btop/issues/new/choose).

## News
### Under development
##### 5 May 2021
This project is gonna take some time until it has complete feature parity with bpytop, since all system information gathering will likely have to be written from scratch without any external libraries.
And will need some help in the form of code contributions to get complete support for BSD and OSX.
If you got suggestions of C++ libraries that are multi-platform and are as extensive as [psutil](https://github.com/giampaolo/psutil) are for python, feel free to open up a new thread in Discussions, it could help speed up the development a lot.
## Documents
#### [CHANGELOG.md](CHANGELOG.md)
#### [CONTRIBUTING.md](CONTRIBUTING.md)
#### [CODE_OF_CONDUCT.md](CODE_OF_CONDUCT.md)
## Description
Resource monitor that shows usage and stats for processor, memory, disks, network and processes.
C++ version and continuation of [bashtop](https://github.com/aristocratos/bashtop) and [bpytop](https://github.com/aristocratos/bpytop).
## Features (at release)
* Easy to use, with a game inspired menu system.
* Full mouse support, all buttons with a highlighted key is clickable and mouse scroll works in process list and menu boxes.
* Fast and responsive UI with UP, DOWN keys process selection.
* Function for showing detailed stats for selected process.
* Ability to filter processes, multiple filters can be entered.
* Easy switching between sorting options.
* Send SIGTERM, SIGKILL, SIGINT to selected process.
* UI menu for changing all config file options.
* Auto scaling graph for network usage.
* Shows message in menu if new version is available
* Shows current read and write speeds for disks
## Themes
Btop++ uses the same theme files as bpytop and bashtop (some color values missing in bashtop themes) .
See [themes](https://github.com/aristocratos/btop/tree/master/themes) folder for available themes.
The `make install` command places the default themes in `/usr/local/share/btop/themes`.
User created themes should be placed in `$HOME/.config/btop/themes`.
Let me know if you want to contribute with new themes.
## Support and funding
You can sponsor this project through github, see [my sponsors page](https://github.com/sponsors/aristocratos) for options.
Or donate through [paypal](https://paypal.me/aristocratos) or [ko-fi](https://ko-fi.com/aristocratos).
Any support is greatly appreciated!
## Prerequisites
For correct display, a terminal with support for:
* 24-bit truecolor ([See list of terminals with truecolor support](https://gist.github.com/XVilka/8346728))
* 256-color terminals are supported through 24-bit to 256-color conversion when setting "truecolor" to False in the options or with "-lc/--low-color" argument.
* Wide characters (Are sometimes problematic in web-based terminals)
Also needs a UTF8 locale and a font that covers:
* Unicode Block “Braille Patterns” U+2800 - U+28FF
* Unicode Block “Geometric Shapes” U+25A0 - U+25FF
* Unicode Block "Box Drawing" and "Block Elements" U+2500 - U+259F
#### Notice (Text rendering issues)
If you are having problems with the characters in the graphs not looking like they do in the screenshots,
it's likely a problem with your systems configured fallback font not having support for braille characters.
See [Terminess Powerline](https://github.com/ryanoasis/nerd-fonts/tree/master/patched-fonts/Terminus/terminus-ttf-4.40.1) for an example of a font that includes the braille symbols.
See comments by @sgleizes [link](https://github.com/aristocratos/bpytop/issues/100#issuecomment-684036827) and @XenHat [link](https://github.com/aristocratos/bpytop/issues/100#issuecomment-691585587) in issue #100 for possible solutions.
If text are misaligned and you are using Konsole or Yakuake, turning off "Bi-Directional text rendering" is a possible fix.
Characters clipping in to each other or text/border misalignments is not bugs caused by bpytop, but most likely a fontconfig or terminal problem where the braille characters making up the graphs aren't rendered correctly.
Look to the creators of the terminal emulator you use to fix these issues if the previous mentioned fixes don't work for you.
## Dependencies
None
But will need G++ 10 or Clang 11 if compiling from source.
## Screenshots

## Installation
#### Manual compilation and installation
>Clone and compile
``` bash
git clone https://github.com/aristocratos/btop.git
cd btop
make
```
>to install
``` bash
sudo make install
```
>to uninstall
``` bash
sudo make uninstall
```
>to clear any compiled files
```bash
make distclean
```
## Configurability
All options changeable from within UI.
Config files stored in "$HOME/.config/btop" folder
#### btop.cfg: (auto generated if not found)
"/etc/bpytop.conf" will be used as default seed for config file creation if it exists. ("/usr/local/etc/bpytop.conf" on BSD)
```bash
#? Config file for btop v. 0.0.1
```
#### Command line options:
```text
usage: btop [-v]
```
