> **Source code spell checker**
|
|
|
|
Finds and corrects spelling mistakes among source code:
|
|
- Fast enough to run on monorepos
|
|
- Low false positives so you can run on PRs

## Install
|
|
|
|
[Download](https://github.com/crate-ci/typos/releases) a pre-built binary
|
|
(installable via [gh-install](https://github.com/crate-ci/gh-install)).
|
|
|
|
Or use rust to install:
|
|
```bash
|
|
cargo install typos-cli
|
|
```
|
|
|
|
Or use [Homebrew](https://brew.sh/) to install:
|
|
```bash
|
|
brew install typos-cli
|
|
```
|
|
## Getting Started
|
|
|
|
Most commonly, you'll either want to see what typos are available with
|
|
```bash
|
|
typos
|
|
```
|
|
|
|
Or have them fixed
|
|
```bash
|
|
typos --write-changes
|
|
typos -w
|
|
```
|
|
If there is any ambiguity (multiple possible corrections), `typos` will just report it to the user and move on.
|
|
|
|
### False-positives
|
|
|
|
Sometimes, what looks like a typo is intentional, like with people's names, acronyms, or localized content.
|
|
|
|
To mark a word or an identifer (grouping of words) as valid, add it your [`_typos.toml`](docs/reference.md) by declaring itself as the valid spelling:
|
|
```toml
|
|
[default.extend-identifiers]
|
|
# *sigh* this just isn't worth the cost of fixing
|
|
AttributeIDSupressMenu = "AttributeIDSupressMenu"
|
|
|
|
[default.extend-words]
|
|
# Don't correct the surname "Teh"
|
|
teh = "teh"
|
|
```
|
|
|
|
For cases like localized content, you can disable spell checking of file contents while still checking the file name:
|
|
```toml
|
|
[type.po]
|
|
extend-glob = ["*.po"]
|
|
check-file = false
|
|
```
|
|
(run `typos --type-list` to see configured file types)
|
|
|
|
If you need some more flexibility, you can completely exclude some files from consideration:
|
|
```toml
|
|
[files]
|
|
extend-exclude = ["localized/*.po"]
|
|
```
|
|
|
|
### Integrations
|
|
|
|
- [GitHub Actions](docs/github-action.md)
|
|
- [pre-commit](docs/pre-commit.md)
|
|
- [🐊Putout Processor](https://github.com/putoutjs/putout-processor-typos)
|
|
|
|
#### Custom
|
|
|
|
`typos` provides several building blocks for custom native integrations
|
|
- `-` reads from `stdin`, `--write-changes` will be written to `stdout`
|
|
- `--diff` to provide a diff
|
|
- `--format json` to get jsonlines with exit code 0 on no errors, code 2 on typos, anything else is an error.
|
|
|
|
Examples:
|
|
```bash
|
|
# Read file from stdin, write corrected version to stdout
|
|
typos - --write-changes
|
|
# Creates a diff of what would change
|
|
typos dir/file --diff
|
|
# Fully programmatic control
|
|
typos dir/file --format json
|
|
```
|
|
|
|
### Debugging
|
|
|
|
You can see what the effective config looks like by running
|
|
```bash
|
|
typos --dump-config -
|
|
```
|
|
|
|
You can then see how typos is processing your project with
|
|
```bash
|
|
typos --files
|
|
typos --identifiers
|
|
typos --words
|
|
```
|
|
|
|
If you need to dig in more, you can enable debug logging with `-v`
|
|
|
|
## FAQ
|
|
|
|
### Why was ... not corrected?
|
|
|
|
tl;dr `typos` doesn't know about it yet
|
|
|
|
`typos` maintains a list of known typo corrections to keep the false positive
|
|
count low so it can safely run unassisted.
|
|
|
|
This is in contrast to most spell checking UIs people use where there is a
|
|
known list of valid words. In this case, the spell checker tries to guess your
|
|
intent by finding the closest-looking word. It then has a gauge for when a
|
|
word isn't close enough and assumes you know best. The user has the
|
|
opportunity to verify these corrections and explicitly allow or reject them.
|
|
|
|
For more on the trade offs of these approaches, see [Design](docs/design.md).
