This seems to be the defacto standard for naming `.po` files. See the GTK source code [1] as an example. I was unable to find any definitive documentation on the naming. Replaces: #10905 [1] https://gitlab.gnome.org/GNOME/gtk/-/tree/main/po?ref_type=heads

Localizing Ghostty: The Translators' Guide
First of all, thanks for helping us localize Ghostty!
To begin contributing, please make sure that you have installed gettext
on your system, which should be available under the gettext package
for most Linux and macOS package managers.
You can install gettext on Windows in a few ways:
- Through an installer;
- Through package managers like Scoop (
scoop install gettext) and WinGet (winget install gettext) which repackages the aforementioned installer; - Through Unix-like environments like Cygwin and MSYS2.
Warning
Unlike what some tutorials suggest, we do not recommend installing
gettextthrough GnuWin32, since it hasn't been updated since 2010 and very likely does not work on modern Windows versions.
You can verify that gettext has been successfully installed by running the
command gettext -V. If everything went correctly, you should see an output like this:
$ gettext -V
gettext (GNU gettext-runtime) 0.21.1

With this, you're ready to localize!
Locale names
A locale name will always consist of a two letter language
code (i.e.
de, es, fr). Sometimes, for languages that have regional variations
(such as zh and es), the locale name will include a two letter
country code.
One example is es_AR for Spanish as spoken in Argentina.
Full locale names are more complicated, but Ghostty does not use all parts. The
gettext documentation
has more information on locale names.
Localization team name
Every locale will have a localization team that helps keep localizations up to
date. Localization team names always consist of a language code and a country
code (e.g. de_DE or zh_CN).
Translation file names
All translation files lie in the po/ directory, including the main template
file called com.mitchellh.ghostty.pot. Do not edit this file. The
template is generated automatically from Ghostty's code and resources, and is
intended to be regenerated by code contributors. If there is a problem with
the template file, please reach out to a code contributor.
Translation file names consist of the locale name and the extension
.po. For example: de.po, zh_CN.po.
Editing translation files
Note
If the translation file for your locale does not yet exist, see the "Creating new translation files" section of this document on how to create one.
The translation file contains a list of entries that look like this:
#. Translators: the category in the right-click context menu that contains split items for all directions
#: src/apprt/gtk/ui/1.0/menu-surface-context-menu.blp:38
# 译注:其他终端程序对 Split 皆有不同翻译,此处采取最直观的翻译方式
msgctxt "Context menu"
msgid "Split"
msgstr "分屏"
The msgid line contains the original string in English, and the msgstr line
should contain the translation for your language. Occasionally there will also
be a msgctxt line that differentiates strings that are identical in English,
based on its context.
Lines beginning with # are comments, of which there are several kinds:
-
Pay attention to comments beginning with
#.. They are comments left by developers providing more context to the string. -
Comments that begin with
#:are source comments: they link the string to source code or resource files. You normally don't need to consider these in your translations. -
You may also leave comments of your own to be read by other translators, beginning with
#. These comments are specific to your locale and don't affect translators in other locales.
The first entry of the .po file has an empty msgid. This entry is special
as it stores the metadata related to the .po file itself. You usually do
not need to modify it.
Creating new translation files
You can use the msginit tool to create new translation files.
Run the command below, replacing X with your locale name.
$ msginit -i po/com.mitchellh.ghostty.pot -l X -o "po/X.po"
msginit may prompt you for other information such as your email address,
which should be filled in accordingly. You can then add your translations
within the newly created translation file.
Afterwards, you need to update the list of known locales within Ghostty's
build system. To do so, open src/os/i18n_locales.zig and find the list of
locale names after the comments, then add your locale name into the list.
The order matters, so make sure to place your locale name in the correct position. Read the comments present in the file for more details on the order. If you're unsure, place it at the end of the list.
const locales = [_][]const u8{
"zh_CN",
// <- Add your locale name here (probably)
}
You should then be able to run zig build run and see your translations in action!
Before opening a pull request with the new translation file, you should also
add your translation file to the CODEOWNERS file. Find the # Localization
section near the bottom and add a line like so (where X.po is the name of the
translation file that you created and Y is your localization team name:
# Localization
/po/README_TRANSLATORS.md @ghostty-org/localization
/po/com.mitchellh.ghostty.pot @ghostty-org/localization
/po/zh_CN.po @ghostty-org/zh_CN
+/po/X.po @ghostty-org/Y
Style Guide
These are general style guidelines for translations. Naturally, the specific recommended standards will differ based on the specific language/locale, but these should serve as a baseline for the tone and voice of any translation.
-
Prefer an instructive, yet professional tone.
In languages that exhibit distinctions based on formality, prefer the formality that is expected of instructive material on the internet. The user should be considered an equal peer of the program and the translator, not an esteemed customer.
-
Use simple to understand language and avoid jargon.
Explain concepts that may be familiar in an English-speaking context, but are uncommon in your language.
-
Do not overly literally translate foreign concepts to your language.
Care should be taken so that your translations make sense to a reader without any background knowledge of the English source text. To localize is to transfer a concept between languages, not to translate each word at face value.
-
Be consistent with stylistic and tonal choices.
Consult the translations made by previous translators, and try to emulate them. Do not overwrite someone else's hard work without substantial justification.
-
Make Ghostty fit in with surrounding applications.
Follow existing translations for terms and concepts if possible, even when they are suboptimal. Follow the writing styles prescribed by the human interface guidelines of each platform Ghostty is available for, including the GNOME Human Interface Guidelines on Linux, and Apple's Human Interface Guidelines on macOS.
