Non-English speaking programmers, do you write your comments in your native language?

This is interesting, I've thought of this before.

I write comments and commit messages in English, mainly because programming is collaborative. I am a member of a local association of young programmers, and in the community (discord, meetups) we speak Finnish, however all interactions on github are in English, so are function and variable names, as well as comments. If someone makes a PR and it's reviewed, it happens in English, even if both parties are native Finns.

This is expected Canadian source code:

// cache the colour in case we need it later for the neighbour
color = fetchColor();
neighbor.color = color;

When language keywords are all written in American English it’s foolish to try to author your code in a different language. But comments are fair game.

German here.

I am not writing anything in my code in German. All of my code, my variables, my default texts, my comments, my documentation, my UI strings, etc. are always and explicitly in English.

The only German I use, is when I provide translations for UI or documentation.

I don't write a lot of codes, but when I do, it is usually a mixture of broken English and my native language.

I write in the official communication language of the company, because that's guaranteed that everyone that will be hired will have to speak that language. I came from Brazil and it is a massive country and most of the population doesn't have access to good English courses, so I like to go with the easiest solution for all future joiners

Always English. I live in a country where developers are hard to find. Chances are that I will get colleagues who do not speak my native language (yet).

I’m French speaking, but I write all code and comments in English, all the time. The code is basically English keywords and symbols, the mix and match just looks weird, makes it harder to share snippets for help or debugging with non-speakers. Especially in code that will be read by other people after the fact, it also tends to make it less likely that this person will be able to understand it - maybe they’ll hire an offshore team or some guy who just immigrated…

Bold of you to assume I write comments.

(Yes, they're usually in my native tongue. I think it's better for you to express your comment clearly then stumble through a different language to make it accessible... chances are you'll be reading that comment next and non-spanish speakers can use Google translate or whatever and ask you if something is unclear).

If I'm working for someone else (company or otherwise), I'll write comments and docs in whatever language I can speak that they want me to (which pretty much means I write comments in English, because I rarely work for Hungarian companies nowadays, and even the ones I did work for preferred English, and these are the only two human languages I can write :().

When working on my own projects, it is always English, because Hungarian doesn't have good translations for many of the technical terms, so half my comments would be English borrowed words anyway. Might aswell write the rest in English too. Also makes it easier for others to chime in, because there are a whole lot more people speaking English than Hungarian.

It was harder in the beginning, when my command of the English language was far worse, but even then, half-Hungarian/Half-English comments just looked weird, and more jarring than full English, even if that English was kinda bad.

No, I once had the displeasure of working with a mixed german english codebase (where also classes and functions were in both languages). It was quite the experience.

I'm Brazilian. For personal projects and snippets, especially if I'm going to share their code publicly (e.g. GitHub or GitHub Gists), I often use English. However, when it's a project from a company I'm working for, I use Portuguese, as every company I've worked for so far are Brazilian (and my coworkers were Brazilian as well).

No, It will look so wierd.

Comments are in English, but output is in German because I only write for myself, my OS has German localization, and English output would look out of place.

Depends. Generally English, unless they are "directed" to one specific person like the professor who's gonna grade it. But even then I might go with English anyway.

Oh I also use my language when I'm leaving an important warning to myself in a config file, like "this is needed because X! don't touch it! If you touch it do Y!"

That depends, actually.

In general, I try to keep everything English, since we do have some international colleagues.

However, I work with a bunch of projects that have some legal/administrative background and certain words have very precisely defined meanings, that can't be easily translated (at least not in one word, so that the next guy can back-translate the word). So in these cases, I sometimes write comments that explain the domain problem in German, because it's much much easier and whoever touches that code better understand the German terms or screw everything up. Unfortunately class and method names are often a weird language mix.

It's not a perfect solution, but given the legal complexities behind seemingly simple words, it's the best of the worst.

They should all be written in Esperanto.

Using English is the only way that all my colleagues are able to read it, but if it’s just meant for you, or only for Spanish speaking people, I’d say why not.

I've always been writing comments and using variable names in English, at all jobs I've had. Probably also the non-professional code before I started writing code professionally.

Part of this is that I've been working in a lot of companies with non-Swedish speakers, and another part is that it's just kind of been expected that the code and everything around it is in English.

In English even when I'm the only person working on the project as there's always the prospect of someone else looking at it. Also my language doesn't use the latin script and I don't want to mix other scripts into code files. You can always write it in latin script but that's really annoying to read. Funnily enough I wouldn't be so against comments in another "big" language like Spanish or German.

I code in English by habit, comments included. I sometines write comments in French when writing code just for me, but code I write that is meant to be used by others is in English.

english

Oh heck no, that would be horrid. Why would anyone willingly mix three languages for the sake of less readability and frustrating the heck out of most other devs?

My language is rtl, so... shit no!

Writing detailed and technical comments in English is easier that saying a simple English sentence in real life for me, lol.

This actually depends on the kind of project. In larger and longterm projects I write my comments in English. In quick jobs like writing a source code generator or data swabbler that I need once or relatively short term, I use German. It does not make much of a difference for me, though, and I have a script that walks over a source tree to find some common German words just in case I had written something in German by accident.

I do write them in English for personal projects. On everything else it depends on the requirements of the project.

I try to write them in English, but some German ones get through, when I am in a hurry or talking to a colleague (in german).

At my job we write everything in english. Code comments, variable names, review comments. Everything. It's just to make everything readable to people who don't know our language because some people in the office are from other countries.

depends on what everyone else on the project is doing

...why is this nsfw exactly?

Yes of course. For collaboration with current and future remote abroad workers. Also in my country almost everyone speaks English.

I'm not a native English speaker, current country is non-English as well (ahora es español) . My comments have always been in English.
I review and deal with a lot of code from different countries, and it's always annoying if I have to throw the comments through a translator, if I think I'm not understanding the comment well enough.

I only know how to write English, but if I knew writing in multiple languages I would write the comment in both languages
