# inclean

_English | [简体中文](docs/README.zh-CN.md)_

A C/C++ `#include` path normalizer.

Many legacy C/C++ libraries `#include` headers by bare filename
(`#include "bar.h"`) even though the actual header lives several
directories deep (`src/internal/bar.h`). To consume such a library a
caller must add every internal directory to their `-I` list — which
pollutes their include namespace and breaks the library's
encapsulation.

`inclean` does a one-shot, source-level normalization. It scans every
source file in the library and rewrites each `#include` so it resolves
cleanly against a small, explicit set of allowed include directories.
After running `inclean`, consumers only `-I` the allowed directories.

## Install

`inclean` is published to **crates.io**, **PyPI**, and as prebuilt
binaries on **GitHub Releases**. Pick whichever ecosystem you already
have on your machine.

### Via PyPI (Python wheels — no Rust toolchain needed)

Three options:

```sh
uv tool install inclean      # isolated, fastest
pipx install inclean         # isolated
pip install inclean          # into the current environment
```

The wheels ship the native binary built by maturin; `inclean` lands on
your `PATH` the same way `ruff` or `uv` do. Requires Python ≥ 3.8.

### Via cargo

Two options:

```sh
cargo binstall inclean       # prebuilt binary from GitHub Releases (no compilation)
cargo install inclean        # build from crates.io
```

`cargo binstall` fetches inclean's binstall metadata from crates.io and downloads the
matching prebuilt archive from this repo's GitHub Releases (no
compilation).
`cargo binstall` is a third-party cargo subcommand — install it first
via [cargo-bins/cargo-binstall](https://github.com/cargo-bins/cargo-binstall)
if you don't already have it.

`cargo install` downloads the source from crates.io and compiles it locally.

### Prebuilt binaries (no package manager)

Download a tarball for your platform from the
[latest GitHub Release](https://github.com/inaku-Gyan/inclean/releases/latest)
and put `inclean` (or `inclean.exe`) on your `PATH`.

### From repo source

Clone this repo and build from source:

```sh
git clone https://github.com/inaku-Gyan/inclean.git
cd inclean
cargo install --path .
```

## Quick start

`inclean` is driven by an `inclean.toml` placed at the root of the
library you want to clean up. A typical workflow:

```sh
inclean init                # write a documented starter inclean.toml
$EDITOR inclean.toml        # tell it where your headers live
inclean check               # dry-run: report every proposed change
inclean diff                # see the rewrites as a unified diff
inclean apply               # write the rewrites in place
```

`check` / `diff` / `apply` optionally take `[PATHS...]` to restrict
which files are processed; with no paths they consider every source
file under the project root. `-c PATH` overrides the upward `inclean.toml`
walk; `-j N` sets the worker thread count.

Rule matching first checks `file_paths`, `file_suffixes`, `include_forms`,
and `include_match`. Globs are anchored and use literal separators:
`foo.h` only matches `foo.h`, while `**/foo.h` matches at any depth.
Glob lists are ordered: a leading unescaped `!` excludes, and the last
matching pattern wins. Use TOML single quotes for a literal leading bang,
for example `'\!weird.h'`; in double quotes, write `"\\!weird.h"`.
When `include_directories` is set, inclean then probes those literal
directories and applies `include_on_unresolved` (`error` / `skip` /
`allow`) and `include_on_ambiguous` (`error` / `skip` / `first`).
For rules that are meant to affect only one side of a rewrite, the whole
field values `action = "skip"` and `trailing_comment = "skip"` make that
side opt out of conflict detection. `keep` still participates in conflict
checks; `skip` does not. For a rule without `copied_from`, both fields
default to `skip` when omitted.

### Example

A simple `replace`-action config that rewrites `#include "foo.h"` to
`#include "lib/foo.h"`:

```toml
[project]
root = "."
version = "0.3.0-alpha.3"
min_inclean_version = "0.3.0-alpha.3"

[[rule]]
name = "lib-prefix"
file_paths = ["src/**/*"]
include_match = ["foo.h", "bar.h"]
action = { type = "replace", with = "lib/${original}" }
```

See [tests/golden_tests/](tests/golden_tests/) for runnable end-to-end examples.

## Editor support

`inclean.toml` ships with a JSON Schema for editor completion and
validation. Editors that understand the `#:schema` directive (VS Code
with [Even Better TOML](https://marketplace.visualstudio.com/items?itemName=tamasfe.even-better-toml),
Helix, Zed) automatically pick it up:

```toml
#:schema https://raw.githubusercontent.com/inaku-Gyan/inclean/v1.2.3/schemas/inclean.toml.schema.json

[project]
root = "."
version = "1.2.3"
min_inclean_version = "1.1.0"
```

(The above version numbers are just examples.)

`inclean init` writes both the `#:schema` line (for the editor) and the
`[project].version` + `[project].min_inclean_version` fields, each
pinned to the CLI version that generated the file. To upgrade schema
validation, edit the version segment in the URL to a newer release tag.

**`#:schema` and the `[project]` version fields are independent.** The
`#:schema` URL is purely for editor tooling; the CLI runs its own
two-direction compatibility check (`CLI_COMPAT_MIN <= cfg.version` AND
`cfg.min_inclean_version <= CLI_CURRENT`). inclean is pre-1.0 and does
not ship migration shims for breaking schema changes — see
[CLAUDE.md](CLAUDE.md#pre-10-backward-compat-policy).

You can also dump a local copy:

```sh
inclean config schema --output inclean.toml.schema.json
```
