# Gender-neutral Chromium code

## Why this is important

Some points in our code, documentation and comments contain needless assumptions
about the gender of a future reader, user, etc. __Example: "When the user logs
into his profile."__

Our [Code of Conduct](https://www.chromium.org/conduct) under "Be respectful and
constructive" says:

> Each of us has the right to __enjoy our experience__ and participate without
> fear of harassment, __discrimination__, or __condescension__, whether blatant
> or subtle.

Emphasis is added: unnecessarily gendered code is discriminatory and
condescending, and reading biased code isn't enjoyable.

## Suggestions on how to keep code gender-neutral

These are only suggestions. You make the call. 

Things to avoid:

* Gendered pronouns: he / she / him / her / his / hers, etc.
* Instances of the phrases "he or she", "his/hers", "(s)he", etc. All of these
  still exclude those who don't identify with either gender, and implicitly
  (slightly) favor one gender via listing it first.
* "Guys" as a gender-neutral term, which has male associations. Usually in
  comments it implies anthropomorphism of inanimate objects and should be
  replaced with a more precise technical term. If it does refer to people,
  consider using "everyone", "folks", "people", "peeps", "y'all", etc.
* Other gendered words: "brother", "mother", "man", etc.

Cases that are likely fine to leave alone include:

* References to a specific person ("Rachel is on leave; update this when she is
  back.").
* A name ("Guy" and "He" are both valid names).
* A language code ("he" is the ISO 639-1 language code for Hebrew).
* He as an abbreviation for "helium".
* The Spanish word "he".
* References to a specific fictional person ([Alice, Bob, ...](http://en.wikipedia.org/wiki/Alice_and_Bob)).
  * For new code/comments, consider using just 'A', 'B' as names.
* Quotations and content of things like public-domain books.
* Partner agreements and legal documents we can no longer edit.
* Occurrences in randomly generated strings or base-64 encodings.
* Content in a language other than English unless you are fluent in that
  language.

How to change the remaining awkward intrusions of gender:

* Try rewording things to not involve a pronoun at all. In many cases this makes
  the documentation clearer. Example: "I tell him when I am all done." → "I tell
  the owner when I am all done." This saves the reader a tiny bit of mental
  pointer-dereferencing.
* Try using [singular they](https://en.wikipedia.org/wiki/Singular_they).
* Try making hypothetical people plural. "When the user is done he'll
  probably..."
→ "When users complete this step, they probably...".
* When referring to a non-person, "it" or "one" may be good alternatives ([wikipedia link](http://wikipedia.org/wiki/Gender-specific_and_gender-neutral_pronouns#It_and_one_as_gender-neutral_pronouns)).

## Tools

* [Here](https://cs.chromium.org/search/?q=%28%5E%7C%5Cs%7C%5C%28%7C%5C%5B%29%28%5BHh%5De%7C%5BSs%5Dhe%7C%5BHh%5Dis%7C%5BHh%5Ders?%7C%5BHh%5Dim%7C%5BHh%5Der%7C%5BGg%5Duys?%29%5Cb&sq=package:chromium&type=cs)
  is a code search link prepopulated with a search that finds a lot of gendered
  terms.
* To search for files containing gendered terms, use this command (or a variant
  of it):
```
git grep -wiEIl \ '(he)|(she)|(his)|(hers)|(him)|(her)|(guy)|(guys)'
```
* To search in a file open in vim for gendered terms, use this command:
```
/\<he\>\|\<she\>\|\<his\>\|\<hers\>\|\<him\>\|\<her\>\|\<guy\>\|\<guys\>|\<man\>\c
```
* There are presubmit checks available for this that are run for the infra and
  v8 repos. They are not run for other repos as there are too many false
  positives.
