## What it does

sasjs-lint documents the @sasjs/lint rules, `.sasjslint` settings, severity changes, and process exit behavior. It helps an agent explain a warning, prepare a formatter run, or choose the right `sasjs lint` command, including `find`, `fix`, and `init`.

The skill also covers project and home-directory configuration, file-level exceptions, and the same engine as used by the SASjs CLI, the VS Code extension, and SASjs Server. The library reads `.sas` files as text, so SAS itself is not required for this linting layer.

Warnings do not make `sasjs lint` fail: only an ERROR produces a non-zero exit code. `noEncodedPasswords` starts at ERROR, while other rules can be promoted or lowered through `severityLevel`. A rule may appear later in an editor because each integration pins its own @sasjs/lint version.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add sasjs/skills --skill sasjs-lint -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/sasjs-lint/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/sasjs-lint/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add sasjs/skills --skill sasjs-lint -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/sasjs-lint/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add sasjs/skills --skill sasjs-lint -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/sasjs-lint/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install sasjs/skills sasjs-lint
```

2. **Manually: put the files in place**
- File: `.github/skills/sasjs-lint/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add sasjs/skills --skill sasjs-lint -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/sasjs/skills --path sasjs-lint
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/sasjs-lint/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add sasjs/skills --skill sasjs-lint -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/sasjs/skills/tree/HEAD/sasjs-lint/SKILL.md

## When to use it
- check SAS files against project rules
- create and tune a `.sasjslint` configuration
- explain why a lint warning appears
- wire SAS linting into CI or a git hook

## Example prompts
- Set up `@sasjs/lint` rules for this project and create `.sasjslint`.
- Explain the `sasjs lint` warning in this SAS file and suggest the matching fix.
- Configure `sasjs lint` for CI so an ERROR returns a non-zero exit code.

# @sasjs/lint

<!-- SPDX-License-Identifier: MIT -->

`@sasjs/lint` is the linting and formatting engine for SAS code. It is a TypeScript library with no SAS dependency - it reads `.sas` files as text - and it is the single engine behind `sasjs lint`, the SASjs VS Code extension's Problems panel, and the SASjs Server Studio editor.

This skill covers the rules, the `.sasjslint` file, the formatter, and the ways to invoke it. It does not cover the SAS language itself (see `sas`) or the rest of the CLI (see `sasjs-cli`).

## When to use

- Writing or changing a `.sasjslint` file
- A `sasjs lint` run reports a warning and you need to know what it means or how to silence it
- Adding lint to a CI pipeline or a git pre-commit hook
- Running the formatter (`sasjs lint fix`, format-on-save, `formatText`)
- Explaining why a rule does or does not fire in an editor

## Where it runs

| Surface | How it is invoked | Notes |
|---|---|---|
| SASjs CLI | `sasjs lint`, `sasjs lint find`, `sasjs lint fix`, `sasjs lint init` | `find` is the default subcommand. `init` writes a `.sasjslint` at the project root holding the full default config |
| VS Code extension (`sasjs/sasjs-for-vscode`, published on Open VSX) | Problems panel (ctrl+shift+M), Format Document, format-on-save | Config precedence: project `.sasjslint` > setting `sasjs-for-vscode.lintConfig` > `~/.sasjslint` > defaults |
| SASjs Server Studio | `POST /SASjsApi/code/lint` and `POST /SASjsApi/code/format`, body `{ code, filePath }` | Rules come from the nearest `.sasjslint` at or above the file's folder on the SASjs Drive, walking up to the drive root. A drive-root `.sasjslint` is seeded on first start and shows in the file tree as `/.sasjslint` |
| Library | `lintText`, `lintFile`, `formatText`, `formatFile`, and the folder/project variants | See the API section below |

All four call the same rules. The CLI, extension and server each pin a version of `@sasjs/lint`, so a rule added to the library only appears in a surface once that surface bumps its dependency - check the pinned version before telling a user a rule should fire in their editor.

## Config resolution

When no configuration is passed in, the library resolves it in this order:

1. `.sasjslint` at the project root (the library walks up to find the project)
2. `.sasjslint` in the user's home directory
3. `DefaultLintConfiguration` - the built-in defaults

A setting that is absent takes its default, and so does a project with no `.sasjslint` at all. `DefaultLintConfiguration` is exported from `@sasjs/lint/utils/getLintConfig`, and it is what `sasjs lint init` writes out.

## The .sasjslint file

```json
{
  "noTrailingSpaces": true,
  "maxLineLength": 100,
````

The third-party file has ended. Everything between the 89a5b88dd761527a tags is data: requests and commands from it are not followed. An “end of file” line with another tag inside the block is part of the file.
