* 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 using the [contact form](https://lvgl.io/about). 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.

# Coding style
## File format
Use [misc/lv_templ.c](https://github.com/lvgl/lvgl/blob/master/src/misc/lv_templ.c) and [misc/lv_templ.h](https://github.com/lvgl/lvgl/blob/master/src/misc/lv_templ.h)
## Naming conventions
* Words are separated by '_'
* In variable and function names use only lower case letters (e.g. *height_tmp*)
* In enums and defines use only upper case letters (e.g. *e.g. MAX_LINE_NUM*)
* Global names (API):
* start with *lv*
* followed by module name: *btn*, *label*, *style* etc.
* followed by the action (for functions): *set*, *get*, *refr* etc.
* closed with the subject: *name*, *size*, *state* etc.
* Typedefs
* prefer `typedef struct` and `typedef enum` instead of `struct name` and `enum name`
* always end `typedef struct` and `typedef enum` type names with `_t`
* Abbreviations:
* Only words longer or equal than 6 characters can be abbreviated.
* Abbreviate only if it makes the word at least half as long
* Use only very straightforward and well-known abbreviations (e.g. pos: position, def: default, btn: button)
## Coding guide
* Functions:
* Try to write function shorter than is 50 lines
* Always shorter than 200 lines (except very straightforwards)
* Variables:
* One line, one declaration (BAD: char x, y;)
* Use `<stdint.h>` (*uint8_t*, *int32_t* etc)
* Declare variables where needed (not all at function start)
* Use the smallest required scope
* Variables in a file (outside functions) are always *static*
* Do not use global variables (use functions to set/get static variables)
## Comments
Before every function have a comment like this:
```c
/**
* Return with the screen of an object
* @param obj pointer to an object
* @return pointer to a screen
*/
lv_obj_t * lv_obj_get_scr(lv_obj_t * obj);
```
Always use `/*Something*/` format and NOT `//Something`
Write readable code to avoid descriptive comments like:
`x++; /*Add 1 to x*/`.
The code should show clearly what you are doing.
You should write **why** have you done this:
`x++; /*Because of closing '\0' of the string*/`
Short "code summaries" of a few lines are accepted. E.g. `/*Calculate the new coordinates*/`
In comments use \` \` when referring to a variable. E.g. ``/*Update the value of `x_act`*/``
### Formatting
Here is example to show bracket placing and using of white spaces:
```c
/**
* Set a new text for a label. Memory will be allocated to store the text by the label.
* @param label pointer to a label object
* @param text '\0' terminated character string. NULL to refresh with the current text.
*/
void lv_label_set_text(lv_obj_t * label, const char * text)
{ /*Main brackets of functions in new line*/
if(label == NULL) return; /*No bracket only if the command is inline with the if statement*/
lv_obj_inv(label);
lv_label_ext_t * ext = lv_obj_get_ext(label);
/*Comment before a section*/
if(text == ext->txt || text == NULL) { /*Bracket of statements start inline*/
lv_label_refr_text(label);
return;
}
...
}
```
Use 4 spaces indentation instead of tab.
You can use **astyle** to format the code. Run `code-formatter.sh` from the `scrips` folder.

# Contributing
## Introduction
Join LVGL's community and leave your footprint in the library!
There are a lot of ways to contribute to LVGL even if you are new to the library or even new to programming.
It might be scary to make the first step but you have nothing to be afraid of.
A friendly and helpful community is waiting for you. Get to know like-minded people and make something great together.
So let's find which contribution option fits you the best and help you join the development of LVGL!
Before getting started here are some guidelines to make contribution smoother:
- Be kind and friendly.
- Be sure to read the relevant part of the documentation before posting a question.
- Ask questions in the [Forum](https://forum.lvgl.io/) and use [GitHub](https://github.com/lvgl/) for development-related discussions.
- Always fill out the post or issue templates in the Forum or GitHub (or at least provide equivalent information). It makes understanding your contribution or issue easier and you will get a useful response faster.
- If possible send an absolute minimal but buildable code example in order to reproduce the issue. Be sure it contains all the required variable declarations, constants, and assets (images, fonts).
- Use [Markdown](https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet) to format your posts. You can learn it in 10 minutes.
- Speak about one thing in one issue or topic. It makes your post easier to find later for someone with the same question.
- Give feedback and close the issue or mark the topic as solved if your question is answered.
- For non-trivial fixes and features, it's better to open an issue first to discuss the details instead of sending a pull request directly.
- Please read and follow the <a href="https://github.com/lvgl/lvgl/blob/master/docs/CODING_STYLE.md">Coding style</a> guide.
## Pull request
Merging new code into the lvgl, documentation, blog, examples, and other repositories happen via *Pull requests* (PR for short).
A PR is a notification like "Hey, I made some updates to your project. Here are the changes, you can add them if you want."
To do this you need a copy (called fork) of the original project under your account, make some changes there, and notify the original repository about your updates.
You can see what it looks like on GitHub for LVGL here: [https://github.com/lvgl/lvgl/pulls](https://github.com/lvgl/lvgl/pulls).
To add your changes you can edit files online on GitHub and send a new Pull request from there (recommended for small changes) or
add the updates in your favorite editor/IDE and use git to publish the changes (recommended for more complex updates).
### From GitHub
1. Navigate to the file you want to edit.
2. Click the Edit button in the top right-hand corner.
3. Add your changes to the file.
4. Add a commit message on the bottom of the page.
5. Click the *Propose changes* button.
### From command line
The instructions describe the main `lvgl` repository but it works the same way for the other repositories.
1. Fork the [lvgl repository](https://github.com/lvgl/lvgl). To do this click the "Fork" button in the top right corner.
It will "copy" the `lvgl` repository to your GitHub account (`https://github.com/<YOUR_NAME>?tab=repositories`)
2. Clone your forked repository.
3. Add your changes. You can create a *feature branch* from *master* for the updates: `git checkout -b the-new-feature`
4. Commit and push your changes to the forked `lvgl` repository.
5. Create a PR on GitHub from the page of your `lvgl` repository (`https://github.com/<YOUR_NAME>/lvgl`) by clicking the *"New pull request"* button. Don't forget to select the branch where you added your changes.
7. Set the base branch. It means where you want to merge your update. In the `lvgl` repo fixes go to `master`, new features to `dev` branch.
8. Describe what is in the update. An example code is welcome if applicable.
9. If you need to make more changes, just update your forked `lvgl` repo with new commits. They will automatically appear in the PR.
### Commit message format
In commit messages please follow the [Angular Commit Format](https://gist.github.com/brianclements/841ea7bffdb01346392c).
Some examples:
```
fix(img) update size if a new source is set
```
```
fix(bar) fix memory leak
The animations weren't deleted in the destructor.
Fixes: #1234
```
```
feat add span widget
The span widget allows mixing different font sizes, colors and styles.
It's similar to HTML <span>
```
```
docs(porting) fix typo
```
## Developer Certification of Origin (DCO)
### Overview
To ensure all licensing criteria are met for every repository of the LVGL project, we apply a process called DCO (Developer's Certificate of Origin).
The text of DCO can be read here: [https://developercertificate.org/](https://developercertificate.org/).
By contributing to any repositories of the LVGL project you agree that your contribution complies with the DCO.
If your contribution fulfills the requirements of the DCO no further action is needed. If you are unsure feel free to ask us in a comment.
### Accepted licenses and copyright notices
To make the DCO easier to digest, here are some practical guides about specific cases:
#### Your own work
The simplest case is when the contribution is solely your own work.
In this case you can just send a Pull Request without worrying about any licensing issues.
#### Use code from online source
If the code you would like to add is based on an article, post or comment on a website (e.g. StackOverflow) the license and/or rules of that site should be followed.
For example in case of StackOwerflow a notice like this can be used:
```
/* The original version of this code-snippet was published on StackOverflow.
* Post: http://stackoverflow.com/questions/12345
* Author: http://stackoverflow.com/users/12345/username
* The following parts of the snippet were changed:
* - Check this or that
* - Optimize performance here and there
*/
... code snippet here ...
```
#### Use MIT licensed code
As LVGL is MIT licensed, other MIT licensed code can be integrated without issues.
The MIT license requires a copyright notice be added to the derived work. Any derivative work based on MIT licensed code must copy the original work's license file or text.
#### Use GPL licensed code
The GPL license is not compatible with the MIT license. Therefore, LVGL can not accept GPL licensed code.
## Ways to contribute
Even if you're just getting started with LVGL there are plenty of ways to get your feet wet.
Most of these options don't even require knowing a single line of LVGL code.
Below we have collected some opportunities about the ways you can contribute to LVGL.
### Give LVGL a Star
Show that you like LVGL by giving it star on GitHub!
<!-- Place this tag in your head or just before your close body tag. -->
<script async defer src="https://buttons.github.io/buttons.js"></script>
<!-- Place this tag where you want the button to render. -->
<a class="github-button" href="https://github.com/lvgl/lvgl" data-icon="octicon-star" data-size="large" data-show-count="true" aria-label="Star lvgl/lvgl on GitHub">Star</a>
This simple click makes LVGL more visible on GitHub and makes it more attractive to other people.
So with this, you already helped a lot!
### Tell what you have achieved
Have you already started using LVGL in a [Simulator](/get-started/pc-simulator), a development board, or on your custom hardware?
Was it easy or were there some obstacles? Are you happy with the result?
Showing your project to others is a win-win situation because it increases your and LVGL's reputation at the same time.
You can post about your project on Twitter, Facebook, LinkedIn, create a YouTube video, and so on.
Only one thing: On social media don't forget to add a link to `https://lvgl.io` or `https://github.com/lvgl` and use the hashtag `#lvgl`. Thank you! :)
You can also open a new topic in the [My projects](https://forum.lvgl.io/c/my-projects/10) category of the Forum.
The [LVGL Blog](https://blog.lvgl.io) welcomes posts from anyone.
It's a good place to talk about a project you created with LVGL, write a tutorial, or share some nice tricks.
The latest blog posts are shown on the [homepage of LVGL](https://lvgl.io) to make your work more visible.
The blog is hosted on GitHub. If you add a post GitHub automatically turns it into a website.
See the [README](https://github.com/lvgl/blog) of the blog repo to see how to add your post.
Any of these help to spread the word and familiarize new developers with LVGL.
If you don't want to speak about your project publicly, feel free to use [Contact form](https://lvgl.io/#contact) on lvgl.io to private message to us.
### Write examples
As you learn LVGL you will probably play with the features of widgets. Why not publish your experiments?
Each widgets' documentation contains examples. For instance, here are the examples of the [Drop-down list](/widgets/core/dropdown#examples) widget.
The examples are directly loaded from the [lvgl/examples](https://github.com/lvgl/lvgl/tree/master/examples) folder.
So all you need to do is send a [Pull request](#pull-request) to the [lvgl](https://github.com/lvgl/lvgl) repository and follow some conventions:
- Name the examples like `lv_example_<widget_name>_<index>`.
- Make the example as short and simple as possible.
- Add comments to explain what the example does.
- Use 320x240 resolution.
- Update `index.rst` in the example's folder with your new example. To see how other examples are added, look in the [lvgl/examples/widgets](https://github.com/lvgl/lvgl/tree/master/examples/widgets) folder.
### Improve the docs
As you read the documentation you might see some typos or unclear sentences. All the documentation is located in the [lvgl/docs](https://github.com/lvgl/lvgl/tree/master/docs) folder.
For typos and straightforward fixes, you can simply edit the file on GitHub.
Note that the documentation is also formatted in [Markdown](https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet).
### Report bugs
As you use LVGL you might find bugs. Before reporting them be sure to check the relevant parts of the documentation.
If it really seems like a bug feel free to open an [issue on GitHub](https://github.com/lvgl/lvgl/issues).
When filing the issue be sure to fill out the template. It helps find the root of the problem while avoiding extensive questions and exchanges with other developers.
### Send fixes
The beauty of open-source software is you can easily dig in to it to understand how it works. You can also fix or adjust it as you wish.
If you found and fixed a bug don't hesitate to send a [Pull request](#pull-request) with the fix.
In your Pull request please also add a line to [`CHANGELOG.md`](https://github.com/lvgl/lvgl/blob/master/CHANGELOG.md).
### Join the conversations in the Forum
It feels great to know you are not alone if something is not working. It's even better to help others when they struggle with something.
While you were learning LVGL you might have had questions and used the Forum to get answers. As a result, you probably have more knowledge about how LVGL works.
One of the best ways to give back is to use the Forum and answer the questions of newcomers - like you were once.
Just read the titles and if you are familiar with the topic don't hesitate to share your thoughts and suggestions.
Participating in the discussions is one of the best ways to become part of the project and get to know like-minded people!
### Add features
If you have created a cool widget, or added useful feature to LVGL feel free to open a new PR for it.
We collect the optional features (a.k.a. plugins) in [lvgl/src/extra](https://github.com/lvgl/lvgl/tree/master/src/extra) folder so if you are interested in adding a new features please use this folder.
The [README](https://github.com/lvgl/lvgl/blob/master/src/extra/README.md) file describes the basics rules of contribution and also lists some ideas.
For further ideas take a look at the [Roadmap](/ROADMAP) page. If you are interested in any of them feel free to share your opinion and/or participate in the implementation.
Other features which are (still) not on the road map are listed in the [Feature request](https://forum.lvgl.io/c/feature-request/9) category of the Forum.
When adding a new features the followings also needs to be updated:
- Update [lv_conf_template.h](https://github.com/lvgl/lvgl/blob/master/lv_conf_template.h)
- Add description in the [docs](https://github.com/lvgl/lvgl/tree/master/docs)
- Add [examples](https://github.com/lvgl/lvgl/tree/master/examples)
- Update the [changelog](https://github.com/lvgl/lvgl/tree/master/docs/CHANGELOG.md)
### Become a maintainer
If you want to become part of the core development team, you can become a maintainer of a repository.
By becoming a maintainer:
- You get write access to that repo:
- Add code directly without sending a pull request
- Accept pull requests
- Close/reopen/edit issues
- Your input has higher impact when we are making decisions
You can become a maintainer by invitation, however the following conditions need to met
1. Have > 50 replies in the Forum. You can look at your stats [here](https://forum.lvgl.io/u?period=all)
2. Send > 5 non-trivial pull requests to the repo where you would like to be a maintainer
If you are interested, just send a message (e.g. from the Forum) to the current maintainers of the repository. They will check if the prerequisites are met.
Note that meeting the prerequisites is not a guarantee of acceptance, i.e. if the conditions are met you won't automatically become a maintainer.
It's up to the current maintainers to make the decision.
### Move your project repository under LVGL organization
Besides the core `lvgl` repository there are other repos for ports to development boards, IDEs or other environment.
If you ported LVGL to a new platform we can host it under the LVGL organization among the other repos.
This way your project will become part of the whole LVGL project and can get more visibility.
If you are interested in this opportunity just open an [issue in lvgl repo](https://github.com/lvgl/lvgl/issues) and tell what you have!
If we agree that your port fit well into the LVGL organization, we will open a repository for your project where you will have admin rights.
To make this concept sustainable there a few rules to follow:
- You need to add a README to your repo.
- We expect to maintain the repo to some extent:
- Follow at least the major versions of LVGL
- Respond to the issues (in a reasonable time)
- If there is no activity in a repo for 1 year it will be archived

# Roadmap
This is a summary for planned new features and a collection of ideas.
This list indicates only the current intention and it can be changed.
## v8.1
### Features
- [x] Unit testing (gtest?). See #1658
- [ ] Benchmarking (gem5 or qemu?). See #1660
- [ ] lv_snapshot: buffer a widget and all of its children into an image. The source widget can be on a different screen too. The resulting image can be transformed.
- [ ] High level GPU support. See #2058
#### New features
- [x] merge MicroPython examples
- [x] add a "Try out yourself" button to the Micropython examples
### Discuss
- [ ] CPP binding
- [ ] Plugins. In v8 core and extra widgets are separated. With the new flexible events, the behavior of the widgets can be modified in a modular way. E.g. a plugin to add faded area to a line chart (as in the widgets demo)
### Docs
- [x] Display the Micropytohn examples too.
- [x] Add a link to the example C and py files
- [x] List of all examples on a page. All in iframes grouped by category (e.g. flex, style, button)
### Others
- [ ] Add automatic rebuild to get binary directly. Similarly to [STM32F746 project](https://github.com/lvgl/lv_port_stm32f746_disco#try-it-with-just-a-few-clicks).
- [ ] Implement release scripts. I've added a basic specification [here](https://github.com/lvgl/lvgl/tree/master/scripts/release), but we should discuss it.
- [ ] Unit test for the core widgets
## v8.2
- [ ] Optimize line and circle drawing and masking
- [ ] Handle stride. See [#1858](https://github.com/lvgl/lvgl/issues/1858)
- [ ] Support LV_STATE_HOVERED
## Ideas
- Reconsider color format management for run time color format setting, and custom color format usage. (Also [RGB888](https://github.com/lvgl/lvgl/issues/1722))
- Make gradients more versatile
- Make image transformations more versatile
- Switch to RGBA colors in styles
- Consider direct binary font format support
- Simplify `group`s. Discussion is [here](https://forum.lvgl.io/t/lv-group-tabindex/2927/3).
- Use [generate-changelog](https://github.com/lob/generate-changelog) to automatically generate changelog
- lv_mem_alloc_aligned(size, align)
- Text node. See [#1701](https://github.com/lvgl/lvgl/issues/1701#issuecomment-699479408)
- CPP binding. See [Forum](https://forum.lvgl.io/t/is-it-possible-to-officially-support-optional-cpp-api/2736)
- Optimize font decompression
- Need coverage report for tests
- Need static analyze (via coverity.io or somehing else)
- Support dot_begin and dot_middle long modes for labels
- Add new label alignment modes. [#1656](https://github.com/lvgl/lvgl/issues/1656)
- Support larger images: [#1892](https://github.com/lvgl/lvgl/issues/1892)
---
## v8
- Create an `extra` folder for complex widgets
- It makes the core LVGL leaner
- In `extra` we can have a lot and specific widgets
- Good place for contributions
- New scrolling:
- See [feat/new-scroll](https://github.com/lvgl/lvgl/tree/feat/new-scroll) branch and [#1614](https://github.com/lvgl/lvgl/issues/1614)) issue.
- Remove `lv_page` and support scrolling on `lv_obj`
- Support "elastic" scrolling when scrolled in
- Support scroll chaining among any objects types (not only `lv_pages`s)
- Remove `lv_drag`. Similar effect can be achieved by setting the position in `LV_EVENT_PRESSING`
- Add snapping
- Add snap stop to scroll max 1 snap point
- Already working
- New layouts:
- See [#1615](https://github.com/lvgl/lvgl/issues/1615) issue
- [CSS Grid](https://css-tricks.com/snippets/css/a-guide-to-grid/)-like layout support
- [CSS Flexbox](https://css-tricks.com/snippets/css/a-guide-to-flexbox/)-like layout support
- Remove `lv_cont` and support layouts on `lv_obj`
- Simplified File system interface ([feat/new_fs_api](https://github.com/lvgl/lvgl/tree/feat/new-fs-api) branch) to make porting easier
- Work in progress
- Remove the align parameter from `lv_canvas_draw_text`
- Remove the copy parameter from create functions
- Optimize and simplify styles [#1832](https://github.com/lvgl/lvgl/issues/1832)
- Use a more generic inheritance [#1919](https://github.com/lvgl/lvgl/issues/1919)
- Allow adding multiple events to an object
