| description | Add or back-fill user-facing Android strings across all locales in OpenTagViewer. Use whenever adding, renaming or translating any string that appears in the UI, or when checking translations are complete before a PR. |
Adding user-facing strings
The app ships ten locales. A string missing from one silently falls back to English — nothing
fails, and it looks correct in whichever language you happen to read. So every UI string has
to land in every locale in one go.
The rule that matters
Never pass translations through a shell argument. Write a JSON file with the Write tool,
then point the script at it. Passing non-ASCII text through bash -c, sed or a here-doc has
corrupted it twice in this repo — a French apostrophe reached the screen as a literal
\’. The Write tool does not go through shell quoting; a for loop does.
For the same reason, do not hand-edit ten strings.xml files with ten Edit calls unless the
script cannot do what you need. It is slower and it is what the script exists to replace.
Workflow
-
Find out which locales are required — do not assume, they are discovered from the tree:
python scripts/add_strings.py --locales
-
Write the JSON with the Write tool, one entry per string, every locale present:
{
"how_do_i_get_the_zip": {
"default": "How do I get the zip?",
"en": "How do I get the zip?",
"de": "Wie erhalte ich die ZIP-Datei?",
"fr": "Comment obtenir l’archive zip ?",
"nl": "Hoe kom ik aan de zip?",
"ru": "Как получить zip-архив?",
"ja": "zip ファイルの入手方法",
"ko": "zip 파일은 어떻게 받나요?",
"zh-rCN": "如何获取 zip 文件?",
"zh-rTW": "如何取得 zip 檔案?"
}
}
Put it in the scratchpad or tmp/, not in the repo root.
-
Apply, then confirm nothing drifted:
python scripts/add_strings.py tmp/new_strings.json
python scripts/add_strings.py --check
-
Build. aapt is the real judge of whether the XML is acceptable:
JAVA_HOME='C:\Program Files\Android\Android Studio\jbr' ./gradlew.bat :app:assembleDebug
Flags
| Command | What it does |
|---|
add_strings.py (no args) | Prints full usage and the input format |
--locales | Lists discovered locales and their files |
<file.json> | Adds strings; errors if any locale is missing or the name already exists |
--fill <file.json> | Adds only where missing — for back-filling what --check reported |
--show <name>... | Prints existing strings in the input format, ready to edit |
--replace <file.json> | Rewords strings that already exist; errors if one is not defined everywhere |
--remove <name>... | Deletes strings from every locale; errors if a name exists nowhere |
--check | Fails if any locale lacks a string the default locale has. Run before a PR |
Removing and renaming
Do not hand-delete a string from ten files, for the same reason you do not hand-add one:
python scripts/add_strings.py --remove old_name
Renaming is --remove then an ordinary add. Nothing updates references — if a layout or
menu still points at a removed string, aapt fails the build, which is how you want to find
out.
Rewording something that already exists is --show piped into a file, edited, then
--replace. That refuses unless the string is defined in every locale, so a typo in the name
fails instead of quietly doing nothing.
Translating
Translate properly rather than leaving English in place; the existing files are fully
translated and a stray English string is conspicuous. Points that have come up here:
- French uses a space before
:, ? and !, and reads better with ’ than '
- CJK wants the full-width colon
: and, for a gap, the ideographic space
- Keep positional format specifiers (
%1$d, %2$s) intact and in a natural order for the
language — they may be reordered, which is the point of the positional form
- Product names (
Google Maps, AMap, Anisette) generally stay as they are
What the script already handles
Do not do these by hand:
- Escaping
', " and & as Android requires
- Preserving
<u>, <b>, <i> so emphasis survives — styling that belongs to the copy
belongs in the resource, not in a paint flag in code that would only ever apply to English
- Re-parsing each file after writing, so a bad write fails immediately instead of at aapt time
translatable="false" — set "translatable": false and supply only "default"
