# IDE Support
[TOC]
## Odd File Types
EC uses a few odd file types/names. Some are included from other header files
and used to generate data structures, thus it is important for your IDE to index
them.
Patterns | Vague Type
----------------------------------------------------- | ----------
`README.*` | Text
`Makefile.rules`, `Makefile.toolchain` | Makefile
`gpio.wrap` | C Header
`gpio.inc` | C Header
`*.tasklist`, `*.irqlist`, `*.mocklist`, `*.testlist` | C Header
## IDE Configuration Primitives
Due to the way most EC code has been structured, you can typically only safely
inspect a configuration for a single image (RO or RW) for a single board. Thus,
you need to specify the specific board/image pair when requesting defines and
includes.
Command | Description
-------------------------------------------- | ------------------------------
`make print-defines BOARD=$BOARD BLD=RW/RO` | List compiler injected defines
`make print-includes BOARD=$BOARD BLD=RW/RO` | List compiler include paths
## VSCode
You can use the `ide-config.sh` tool to generate a VSCode configuration that
includes selectable sub-configurations for every board/image pair.
1. From the root `ec` directory, do the following:
```bash
mkdir -p .vscode
./util/ide-config.sh vscode all:RW all:RO | tee .vscode/c_cpp_properties.json
```
2. Open VSCode and navigate to some C source file.
3. Run `C/C++ Reset IntelliSense Database` from the `Ctrl-Shift-P` menu
4. Select the config in the bottom right, next to the `Select Language Mode`.
You will only see this option when a C/C++ file is open. Additionally, you
can select a configuration by pressing `Ctrl-Shift-P` and selecting the
`C/C++ Select a Configuration...` option.
5. Add the EC specific file associations and style settings.
Modify `.vscode/settings.json` to have the following elements:
```json
{
"editor.rulers": [80],
"[c]": {
"editor.insertSpaces": false,
"editor.tabSize": 8
},
"files.associations": {
"Makefile.*": "makefile",
"*.inc": "c",
"*.wrap": "c",
"*.tasklist": "c",
"*.irqlist": "c",
"*.mocklist": "c",
"*.testlist": "c"
}
}
```
