📝 alex — Catch insensitive, inconsiderate writing.

Whether your own or someone else’s writing, alex helps you find gender favoring, polarizing, race related, or other unequal phrasing in text.

For example, when We’ve confirmed his identity is given, alex will warn you and suggest using their instead of his.

alex checks things such as:

• Gendered work-titles (if you write garbageman alex suggests garbage collector; if you write landlord alex suggests proprietor)
• Gendered proverbs (if you write like a man alex suggests bravely; if you write ladylike alex suggests courteous)
• Ableist language (if you write learning disabled alex suggests person with learning disabilities)
• Condescending language (if you write obviously or everyone knows alex warns about it)
• Intolerant phrasing (if you write master and slave alex suggests primary and replica)
• Profanities (if you write butt 🍑 alex warns about it)

…and much more!

Note: alex assumes good intent: that you don’t mean to offend!

See retext-equality and retext-profanities for all rules.

alex ignores words meant literally, so “he”, He — ..., and the like are not warned about.

The CLI searches for files with a markdown or text extension when given directories (so $ alex . will find readme.md and path/to/file.txt). To prevent files from being found, create an .alexignore file.

The CLI will sometimes search for files. To prevent files from being found, add a file named .alexignore in one of the directories above the current working directory (the place you run alex from). The format of these files is similar to .eslintignore (which in turn is similar to .gitignore files).

For example, when working in ~/path/to/place, the ignore file can be in to, place, or ~.

The ignore file for this project itself looks like this:

# `node_modules` is ignored by default.
example.md

Sometimes alex makes mistakes:

A message for this sentence will pop up.

Yields:

readme.md
  1:15-1:18  warning  `pop` may be insensitive, use `parent` instead  dad-mom  retext-equality

⚠ 1 warning

HTML comments in Markdown can be used to ignore them:

<!--alex ignore dad-mom-->

A message for this sentence will **not** pop up.

Yields:

readme.md: no issues found

ignore turns off messages for the thing after the comment (in this case, the paragraph). It’s also possible to turn off messages after a comment by using disable, and, turn those messages back on using enable:

<!--alex disable dad-mom-->

A message for this sentence will **not** pop up.

A message for this sentence will also **not** pop up.

Yet another sentence where a message will **not** pop up.

<!--alex enable dad-mom-->

A message for this sentence will pop up.

Yields:

readme.md
  9:15-9:18  warning  `pop` may be insensitive, use `parent` instead  dad-mom  retext-equality

⚠ 1 warning

Multiple messages can be controlled in one go:

<!--alex disable he-her his-hers dad-mom-->

…and all messages can be controlled by omitting all rule identifiers:

<!--alex ignore-->

You can control alex through .alexrc configuration files:

{
  "allow": ["boogeyman-boogeywoman"]
}

…you can use YAML if the file is named .alexrc.yml or .alexrc.yaml:

allow:
  - dad-mom

…you can also use JavaScript if the file is named .alexrc.js:

// But making it random like this is a bad idea!
exports.profanitySureness = Math.floor(Math.random() * 3)

…and finally it is possible to use an alex field in package.json:

{
  …
  "alex": {
    "noBinary": true
  },
  …
}

The allow field should be an array of rules or undefined (the default is undefined). When provided, the rules specified are skipped and not reported.

The deny field should be an array of rules or undefined (the default is undefined). When provided, only the rules specified are reported.

You cannot use both allow and deny at the same time.

The noBinary field should be a boolean (the default is false). When turned on (true), pairs such as he and she and garbageman or garbagewoman are seen as errors. When turned off (false, the default), such pairs are okay.

The profanitySureness field is a number (the default is 0). We use cuss, which has a dictionary of words that have a rating between 0 and 2 of how likely it is that a word or phrase is a profanity (not how “bad” it is):

The profanitySureness field is the minimum rating (including) that you want to check for. If you set it to 1 (maybe) then it will warn for level 1 and 2 (likely) profanities, but not for level 0 (unlikely).

Let’s say example.md looks as follows:

The boogeyman wrote all changes to the **master server**. Thus, the slaves
were read-only copies of master. But not to worry, he was a cripple.

Now, run alex on example.md:

$ alex example.md

Yields:

example.md
   1:5-1:14  warning  `boogeyman` may be insensitive, use `boogeymonster` instead                boogeyman-boogeywoman  retext-equality
  1:42-1:48  warning  `master` / `slaves` may be insensitive, use `primary` / `replica` instead  master-slave           retext-equality
  1:69-1:75  warning  Don’t use `slaves`, it’s profane                                           slaves                 retext-profanities
  2:52-2:54  warning  `he` may be insensitive, use `they`, `it` instead                          he-she                 retext-equality
  2:61-2:68  warning  `cripple` may be insensitive, use `person with a limp` instead             gimp                   retext-equality

When no input files are given to alex, it searches for files in the current directory, doc, and docs. If --mdx is given, it searches for mdx extensions. If --html is given, it searches for htm and html extensions. Otherwise, it searches for txt, text, md, mkd, mkdn, mkdown, ron, and markdown extensions.

This package is ESM only: Node 14+ is needed to use it and it must be imported instead of required.

npm:

$ npm install alex --save

This package exports the identifiers markdown, mdx, html, and text. The default export is markdown.

Check Markdown (ignoring syntax).

The recommended workflow is to add alex to package.json and to run it with your tests in Travis.

You can opt to ignore warnings through alexrc files and control comments.

A package.json file with npm scripts, and additionally using AVA for unit tests, could look like so:

{
  "scripts": {
    "test-api": "ava",
    "test-doc": "alex",
    "test": "npm run test-api && npm run test-doc"
  },
  "devDependencies": {
    "alex": "^1.0.0",
    "ava": "^0.1.0"
  }
}

If you’re using Travis for continuous integration, set up something like the following in your .travis.yml:

 script:
 - npm test
+- alex --diff

Make sure to still install alex though!

If the --diff flag is used, and Travis is detected, lines that are not changes in this push are ignored. Using this workflow, you can merge PRs if it has warnings, and then if someone edits an entirely different file, they won’t be bothered about existing warnings, only about the things they added!

Not a question. And yeah, alex isn’t very smart. People are much better at this. But people make mistakes, and alex is there to help.

See contributing.md on how to get “X” checked by alex.

It’s a nice unisex name, it was free on npm, I like it! 😄

No automated tool can replace studying inclusive communication and listening to the lived experiences of others. An error from alex can be an invitation to learn more. These resources are a launch point for deepening your own understanding and editorial skills beyond what alex can offer:

• The 18F Content Guide has a helpful list of links to other inclusive language guides used in journalism and academic writing.

• The Conscious Style Guide has articles on many nuanced topics of language. For example, the terms race and ethnicity mean different things, and choosing the right word is up to you. Likewise, a sentence that overgeneralizes about a group of people (e.g. “Developers love to code all day”) may not be noticed by alex, but it is not inclusive. A good human editor can step up to the challenge and find a better way to phrase things.

• Sometimes, the only way to know what is inclusive is to ask. In Disability is a nuanced thing, Nicolas Steenhout writes about how person-first language, such as “a person with a disability,” is not always the right choice.

• Language is always evolving. A term that is neutral one year ago can be problematic today. Projects like the Self-Defined Dictionary aim to collect the words that we use to define ourselves and others, and connect them with the history and some helpful advice.

• Unconscious bias is present in daily decisions and conversations and can show up in writing. Textio

  offers some examples of how descriptive adjective choice and tone can push some people away, and how regional language differences can cause confusion.

• Using complex sentences and uncommon vocabulary can lead to less inclusive content. This is described as literacy exclusion in this article by Harver. This is critical to be aware of if your content has a global audience, where a reader’s strongest language may not be the language you are writing in.

This project has a Code of conduct. By interacting with this repository, organization, or community you agree to abide by its terms.

Thanks to @iheanyi for raising the problem and @sindresorhus for inspiring me (@wooorm) to do something about it.

When alex launched, it got some traction on twitter and producthunt. Then there was a lot of press coverage.

Preliminary work for alex was done in 2015. The project was authored by @wooorm.

Lots of people helped since!
