Now that clang-format-14 ubuntu packages are available, it's time to finally upgrade our clang-format version. This version brings with it a bunch of useful features with const-placement being the most notable. These will be enabled in the following commits.

# Using Qt Creator for working with SerenityOS
|
|
|
|
## Setup
|
|
|
|
First, make sure you have a working toolchain and can build and run SerenityOS. Go [here](BuildInstructions.md) for instructions for setting that up.
|
|
|
|
* Install [Qt Creator](https://www.qt.io/offline-installers). You don't need the entire Qt setup, just click 'Qt Creator' on the left side, and install that.
|
|
* Open Qt Creator, select `File -> New File or Project...`
|
|
* Select `Import Existing Project`
|
|
* Give it a name (some tools assume lower-case `serenity`), and navigate to the root of your SerenityOS project checkout. Click Next.
|
|
* Wait for the file list to generate. This can take a minute or two!
|
|
* Ignore the file list, we will overwrite it later. Click Next.
|
|
* Set `Add to version control` to `<None>`. Click Finish.
|
|
* In your shell, go to your SerenityOS project directory, and invoke the `Meta/refresh-serenity-qtcreator.sh` script to regenerate the `serenity.files` file. You will also have to do this every time you delete or add a new file to the project.
|
|
* Edit the `serenity.config` file (In Qt Creator, hit ^K or CMD+K on a Mac to open the search dialog, type the name of the file and hit return to open it)
|
|
* Add the following `#define`s to the file: `SANITIZE_PTRS`, `__serenity__` and `KERNEL`. `__serenity__` define is needed to recognize functions like `unveil`. Depending on what you are working on, you need to have that last define commented out. If you're planning on working in the userland, comment out `#define KERNEL`. If you're working on the Kernel, then uncomment `#define KERNEL`.
|
|
* Edit the `serenity.cxxflags` file to say `-std=c++2a -m32`
|
|
* Edit the `serenity.includes` file to list the following lines:
|
|
|
|
```
|
|
.

|

```
|
|
|
|
Finally, search in the options for "BOM" (Text Editor > Behavior > File Encodings > UTF-8 BOM), and switch to "Always delete".
|
|
|
|
Qt Creator should be set up correctly now, go ahead and explore the project and try making changes. Have fun! :^)
|
|
|
|
## Auto-Formatting
|
|
|
|
You can use `clang-format` to help you with the [style guide](CodingStyle.md). Before you proceed, check that you're actually using clang-format version 14, as some OSes will ship older clang-format versions by default.
|
|
|
|
- In QtCreator, go to "Help > About Plugins…"
|
|
- Find the `Beautifier (experimental)` row (for example, by typing `beau` into the search)
|
|
- Put a checkmark into the box
|
|
- Restart QtCreator if it asks you
|
|
- In QtCreator, go to "Tools > Options…"
|
|
- Type "beau" in the search box, go to "Beautifier > Clang Format"
|
|
- Select the "customized" style, click "edit"
|
|
- Paste the entire content of the file `.clang-format` into the "value" box, and click "OK"
|
|
- In the "Beautifier > General" tab, check "Enable auto format on file save"
|
|
- Select the tool "ClangFormat" if not already selected, and click "OK"
|
|
|
|
Note that not the entire project is clang-format-clean (yet), so sometimes you will see large diffs.
|
|
Use your own judgement whether you want to include such changes. Generally speaking, if it's a few lines then it's a good idea; if it's the entire file then maybe there's a better way to do it, like doing a separate commit, or just ignoring the clang-format changes.
|
|
|
|
You may want to read up what `git add -p` does (or `git checkout -p`, to undo).
|
|
|
|
QtCreator tends to interpret IPC definitions as C++ headers, and then tries to format them. This is not useful. One way to avoid that is telling QtCreator that IPC definitions are not C++ headers.
|
|
- In QtCreator, go to "Tools > Options…"
|
|
- Type "beau" in the search box, go to "Environment > MIME Types"
|
|
- In the little search box, type "plain", and select "text/plain"
|
|
- In the "details" section, you should now see the list of Patterns, something like `*.txt;*.asc;*,v`. Extend it in the following way: `*.txt;*.asc;*,v;*.ipc;*.gml`
|
|
- Click "OK" to close the dialog.
|
|
- Maybe you need to close and open again the IPC files. You can check what QtCreator is doing by right-clicking the filename in the editor tab, and clicking "Properties...". In the third line, you should see `MIME type: text/plain`.
|
|
|
|
## License template
|
|
|
|
You may have noticed how Andreas just types `lic` and the [license appears](https://youtu.be/i0J6J1Twwyo?t=346).
|
|
|
|
In order to so, create a new file anywhere, for example `license-template.creator`, with the standard license:
|
|
|
|
```
|
|
/*
|
|
* Copyright (c) 2021, the SerenityOS developers.
|
|
*
|
|
* SPDX-License-Identifier: BSD-2-Clause
|
|
*/
|
|
```
|
|
|
|
In QtCreator, select the menu "Tools", item "Options", section "C++", tab
|
|
"File Naming" (don't ask me why it's here). At the bottom there should be the
|
|
option "License template:". Click "Browse…", select your file (i.e.,
|
|
`license-template.creator`). Click "OK", and you're done! :)
|
|
|
|
## Compiler Kits
|
|
|
|
You can slightly improve how well Qt interprets the code by adding and setting up an appropriate "compiler kit".
|
|
For that you will need to reference the compilers at `Toolchain/Local/i686/bin/i686-pc-serenity-gcc` and `Toolchain/Local/i686/bin/i686-pc-serenity-g++`.
