How to translate the website

Merge requests about translation, correction, and proofreading are all very welcome. The translation uses Gettext and PO files. The files are located in the po/ directory of the website repository on Framagit. In this directory, the translation consists of 3 parts:

  1. A <locale>.po file with the actual translation source code. This will be compiled by a script into the locale directory.
  2. A <locale>-credits.json file listing the translators for your language
  3. A <locale>.svg file (optional) with the header image font artwork

<locale> is the two letter small-case identifier of the lang used in langs.json.

Translation file reference

1. <locale>.po

To start a new translation, open the _catalog.pot file in a Po editor (see recommended tools below) and save it under po/<locale>.po (replacing <locale> with your language's code from langs.json). Using an editor like this will update the file header correctly for your language. If you need help, please open an issue on GitLab and tag @gunchleoc, or use any of the contact options on the bottom of the website.

The Po file format is human-readable, so you can edit it in a plain text editor if you want. We recommend continuing translation on our Weblate project after creating and submitting an initial file (see the Weblate Guide below). This will give you some automated quality checks on your translation, and you can still download the files to translate in any editor that you like and then upload again. The Weblate project is hosted by Framasoft, just like our GitLab repository.

For translating offline, there are Free/libre and open-source tools available on all operating systems, for example:

  • PoEdit - This tool comes with some automated translation checks that are useful.
  • Virtaal - This tool comes with a translation memory function and will be helpful in restoring older translations. Load the .po file for your locale from the archive into the tool to fill the translation memory before translating the new website files.

Once you opened your file with the tool, you just need to click on the line to translate and fill it. Just repeat the process until you are done and save. Simple! Virtaal also has a lot of convenient keyboard shortcuts.


The previous version of the website was translated into 33 languages. Unfortunately, the format wasn't compatible with the new website and it was hard to translate. But the work done has been preserved in the po/archive folder. If you find a translation, you can open it with a text-editor and see, copy/paste the best ideas. They are archived for reference. We have also created a po version that you can load into your tool to fill its translation memory, and they are also searchable on Weblate.

Special cases:

Sometime you'll come across strings that looks like this:

"Join the <a href=\"%s\">Pepper&Carrot chat room</a> to share your projects!"

It's an HTML link, and you'll need to replicate the syntax if you want your translation to get the link.

You'll also come across the %s symbol:

"This picture is fan-art made by %s."

The website will replace this special character %s with a string (in this case, the name of the author), so, please preserve this symbol.

For numbers, we use %d instead of %s. These are fetched using plural rules. Check the Translatehouse Localization Guide if you don't know the plural rules for your language. If you need further help with understanding the plural rules for your language, open an issue and tag @gunchleoc.

When the same string contains more than one of these placeholders, we number them so that you can change the word order, e.g. from:

"this %1$s can be reversed %2$d times"


"%2$d times, this %1$s can be reversed"

2. <locale>-credits.json

This files define the credits for the translation of the website. In its minimal form, you can write only the credits of the translation.

   "website-translation-credits": {
      "translation": [

The name field supports nicknames (single word) or composed names (many words) and you can add an URL of your choice to it between brackets. Proofreaders and Contributors can also be added. In its full form, the file might look like that:

   "website-translation-credits": {
      "translation": [
         "Lion Blue"
      "proofreading": [
         "Koala Yellow <>",
         "Giraffe Green"
      "contribution": [
         "Cat Carrot <>",
         "Kitten Violet <>"

These data are publicly visible on the website, on the License tab.

3. <locale>.svg

This Inkscape (svg) vector file customise the title used on the front cover of the website, but also on the top title in the navigation bar. This file is optional, no file provided will force the website to use the en.svg version as a fallback. Specifications:

  • 560×120px SVG (you can duplicate en.svg to get same geometry)
  • Black colors to fill the shape.
  • Saved as "Optimized SVG" in Inkscape to crunch the weight of the SVG.

You'll find font artwork already done on many of the header files of the webcomic. If you have trouble making a good-looking title, ask help to other translator (e.g. by opening an issue on the webcomic repository).

4. <locale>.mo

Before the website can use the files, they need to be transformed into binary files. Unless you are running your own website installation for testing, you can ignore this part. If you want to know more, see the po/ on the website project.

Weblate Guide

Define your Languages

After registering an account with Framasoft's Weblate, you need to define which languages you translate. Click on your avatar, then choose Settings, which will put you in the "Languages" tab:

Weblate language settings

The "Secondary languages" are also useful if you want those languages' translations to appear next to the English source strings while translating.

Receive E-mail Notifications

Notification settings are important so that you will know when there are new strings to translate. This way, you won't have to come back and check manually.

Click on your avatar, then choose Settings → Notifications

Weblate notification settings

You can also define special notification settings just for Pepper & Carrot if you want, from the project's main page (see screenshot below).

Translation Project Overview

The Pepper&Carrot Weblate project consists of 3 components:

Weblate project overview

  • archive - DO NOT TRANSLATE: Translations of the legacy website, so that you can search them. This is especially useful for the "Author" page, because we split a very long string into separate parts there.
  • Website: The file to translate.
  • Glossary: The file containing glossary terms, to help you keep consistency in your translation. Glossary terms are shown while you translate the Website file, and you can also add and edit terms there.

File overview

This what the main page of the Website file for your language will look like:

Weblate language overview

Note the translation checks - you can click on a check description to start fixing. Once the checks are clear, use the "Translate" button to translate.

Translation View

While translating, there are different sections with information to help you get context.

Weblate translation interface

  • The "Translation" section is where you do your work. Note that this screenshot shows the French translation along with the English source strings in this screenshot, because I chose it as one of my "Secondary languages" (see Define your Languages above). You can see additional languages' translations in the "Other languages" tab below the "Translation" section.
  • The "Things to Check" section shows any failing automated checks. Make sure to either fix your translation, or dismiss the check if you disagree with it.
  • The "Automatic Suggestions" tab below the "Translation" section shows similar strings that have already been translated. You can also search for keywords there. Do take some time to go through all these tabs find out what they can do for you.
  • The "String Information" section will give you some additional information on the string. If reading a bit of PHP code doesn't scare you, you can use the "Source string location" links to give you more context on a string.

Translating Offline

If you prefer to translate in your own tool (eg. because you prefer your own tool, or because your internet connection is limited), you can download and upload files in Weblate too.

  1. Visit the Website component
  2. Click on your language
  3. Choose "Customise download" from the "Files" menu

Weblate offline translation

If your translation is incomplete, this page will also offer to only download the untranslated strings in order to save bandwidth. Note that it's better to use the complete file if you can though, because it will give you a bit more context for each translation via the surrounding strings.
