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:

# 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:

# 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):

    <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
