# Find Missing Translations
|
|
|
|
## Overview
|
|
|
|
Extract string resource keys from the default `values/strings.xml` that are absent in a target locale's `strings.xml`, excluding non-translatable entries. Outputs a table ready for translation.
|
|
|
|
## When to Use
|
|
|
|
- Need to find untranslated strings for a specific locale
|
|
- Preparing a batch of strings for a translator
|
|
- Checking translation coverage after adding new features
|
|
|
|
## Technique
|
|
|
|
### 1. Identify files
|
|
|
|
```
|
|
Default: amethyst/src/main/res/values/strings.xml
|
|
Target: amethyst/src/main/res/values-<locale>/strings.xml
|
|
```
|
|
|
|
Default locale: `cs-rCZ` if none specified. User may override (e.g., `pt-rBR`, `ja`).
|
|
|
|
### 2. Extract and diff keys
|
|
|
|
Use a single bash pipeline to extract translatable keys from both files and diff them:
|
|
|
|
```bash
|
|
# Extract translatable keys from default (exclude translatable="false")
|
|
comm -23 \
|
|
<(grep '<string name=' amethyst/src/main/res/values/strings.xml \
|
|
| grep -v 'translatable="false"' \
|
|
| sed 's/.*name="\([^"]*\)".*/\1/' | sort) \
|
|
<(grep '<string name=' amethyst/src/main/res/values-<LOCALE>/strings.xml \
|
|
| sed 's/.*name="\([^"]*\)".*/\1/' | sort)
|
|
```
|
|
|
|
This gives the list of missing key names.
|
|
|
|
### 3. Get English values for missing keys
|
|
|
|
For each missing key, extract its English value:
|
|
|
|
```bash
|
|
# For each missing key, extract the full line from default strings.xml
|
|
while IFS= read -r key; do
|
|
grep "name=\"$key\"" amethyst/src/main/res/values/strings.xml
|
|
done < <(comm -23 \
|
|
<(grep '<string name=' amethyst/src/main/res/values/strings.xml \
|
|
| grep -v 'translatable="false"' \
|
|
| sed 's/.*name="\([^"]*\)".*/\1/' | sort) \
|
|
<(grep '<string name=' amethyst/src/main/res/values-<LOCALE>/strings.xml \
|
|
| sed 's/.*name="\([^"]*\)".*/\1/' | sort))
|
|
```
|
|
|
|
### 4. Present results
|
|
|
|
Output the missing entries as raw XML resource lines (copy-paste ready for the locale file):
|
|
|
|
```xml
|
|
<string name="attestation_valid">Valid</string>
|
|
<string name="attestation_valid_from">Valid from %1$s</string>
|
|
<string name="feed_group_lists">Lists</string>
|
|
```
|
|
|
|
Also check `<string-array>` and `<plurals>` tags using the same approach if the project uses them.
|
|
|
|
## Common Mistakes
|
|
|
|
- **Forgetting `translatable="false"`** — these should never appear in locale files
|
|
- **Not checking string-arrays/plurals** — only checking `<string>` misses other resource types
|
|
- **Modifying files** — this is a read-only research task unless the user asks to add entries |
