## Configuration
While **not required** (most settings can be specified in the UI), projects can add an `objdiff.json` (or
`objdiff.yaml`, `objdiff.yml`) file to configure the tool automatically. The configuration file must be located in
While **not required** (most settings can be specified in the UI), projects can add an `objdiff.json` file to configure the tool automatically. The configuration file must be located in
the root project directory.
If your project has a generator script (e.g. `configure.py`), it's recommended to generate the objdiff configuration
file as well. You can then add `objdiff.json` to your `.gitignore` to prevent it from being committed.

### Schema
View [config.schema.json](config.schema.json) for all available options. The below list is a summary of the most important options.
`custom_make` _(optional)_: By default, objdiff will use `make` to build the project.
If the project uses a different build system (e.g. `ninja`), specify it here.
The build command will be `[custom_make] [custom_args] path/to/object.o`.
`custom_args` _(optional)_: Additional arguments to pass to the build command prior to the object path.
`target_dir` _(optional)_: Relative from the root of the project, this where the "target" or "expected" objects are located.
These are the **intended result** of the match.
`base_dir` _(optional)_: Relative from the root of the project, this is where the "base" or "actual" objects are located.
These are objects built from the **current source code**.
`build_target`: If true, objdiff will tell the build system to build the target objects before diffing (e.g.
`make path/to/target.o`).
This is useful if the target objects are not built by default or can change based on project configuration or edits
to assembly files.
Requires the build system to be configured properly.
`build_base`: If true, objdiff will tell the build system to build the base objects before diffing (e.g. `make path/to/base.o`).
It's unlikely you'll want to disable this, unless you're using an external tool to rebuild the base object on source file changes.
`watch_patterns` _(optional)_: A list of glob patterns to watch for changes.
([Supported syntax](https://docs.rs/globset/latest/globset/#syntax))
If any of these files change, objdiff will automatically rebuild the objects and re-compare them.
If not specified, objdiff will use the default patterns listed above.
`objects` _(optional)_: If specified, objdiff will display a list of objects in the sidebar for easy navigation.
`units` _(optional)_: If specified, objdiff will display a list of objects in the sidebar for easy navigation.
> `name` _(optional)_: The name of the object in the UI. If not specified, the object's `path` will be used.
>
> `path`: Relative path to the object from the `target_dir` and `base_dir`.
> Requires `target_dir` and `base_dir` to be specified.
> `target_path`: Path to the "target" or "expected" object from the project root.
> This object is the **intended result** of the match.
>
> `target_path`: Path to the target object from the project root.
> Required if `path` is not specified.
> `base_path`: Path to the "base" or "actual" object from the project root.
> This object is built from the **current source code**.
>
> `base_path`: Path to the base object from the project root.
> Required if `path` is not specified.
> `metadata.auto_generated` _(optional)_: Hides the object from the object list, but still includes it in reports.
>
> `reverse_fn_order` _(optional)_: Displays function symbols in reversed order.
Used to support MWCC's `-inline deferred` option, which reverses the order of functions in the object file.
> `metadata.complete` _(optional)_: Marks the object as "complete" (or "linked") in the object list.
> This is useful for marking objects that are fully decompiled. A value of `false` will mark the object as "incomplete".
