A linter that checks for duplicate words in the source code (usually miswritten)

Examples in real code and related issues can be viewed in [dupword#3](https://github.com/Abirdcfly/dupword/issues/3)

## example

1. Repeated words appear on two adjacent lines [commit](https://github.com/golang/go/commit/d8f90ce0f8119bf593efb6fb91825de5b61fcda7)

## Install

```bash
go install github.com/Abirdcfly/dupword/cmd/dupword@latest
```

**Or** install the main branch (including the last commit) with:

```bash
go install github.com/Abirdcfly/dupword/cmd/dupword@main
```

## Usage

### 1. default

Run with default settings(include test file):

**But note that not all repeated words are wrong** see [dupword#4](https://github.com/Abirdcfly/dupword/issues/4) for real code example.

```bash
$ dupword ./...
/Users/xxx/go/src/dupword/dupword_test.go:88:10: Duplicate words (the) found
exit status 3
```

### 2. skip test file

Skip detection test file(`*_test.go`):

```bash
$ dupword -test=false ./...
```

### 3. auto-fix

```bash
$ dupword -fix ./...
```

### 4. all options

All options:

```bash
$ dupword --help
dupword: checks for duplicate words in the source code (usually miswritten)

Usage: dupword [-flag] [package]

This analyzer checks miswritten duplicate words in comments or package doc or string declaration

Flags:
  -V    print version and exit
  -all
        no effect (deprecated)
  -c int
        display offending line with this many lines of context (default -1)
  -comments-only
        check only comments, skip strings
  -cpuprofile string
        write CPU profile to this file
  -debug string
        debug flags, any subset of "fpstv"
  -diff
        with -fix, don't update the files, but print a unified diff
  -fix
        apply all suggested fixes
  -flags
        print analyzer flags in JSON
  -ignore value
        ignore words
  -json
        emit JSON output
  -keyword value
        keywords for detecting duplicate words
  -memprofile string
        write memory profile to this file
  -source
        no effect (deprecated)
  -tags string
        no effect (deprecated)
  -test
        indicates whether test files should be analyzed, too (default true)
  -trace string
        write trace log to this file
  -v    no effect (deprecated)
```

### 5. my advice

use `--keyword=the,and,a` and `-fix` together. I think that specifying only commonly repeated prepositions can effectively avoid false positives.

see [dupword#4](https://github.com/Abirdcfly/dupword/issues/4) for real code example.

```bash
$ dupword --keyword=the,and,a -fix ./...
```

## TODO

- [x] add this linter to golangci-lint
- [ ] rewrite the detection logic to make it more efficient

## Limitation

1. Only for `*.go` file.But some miswritten occurs in `*.md` or `*.json` file.(example: kubernetes), In this case, my advice is to use [rg](https://github.com/BurntSushi/ripgrep) to do the lookup and replace manually.
2. When use `-fix`, also running `go fmt` in the dark.([This logic is determined upstream](https://github.com/golang/tools/blob/248c34b88a4148128f89e41923498bd86f805b7d/go/analysis/internal/checker/checker.go#L424-L433), the project does not have this part of the code.)
