JLPT Vocabulary Bundle (Offline)

Bundle location

SubMiner expects the JLPT term-meta bank files to be available locally at:

• vendor/yomitan-jlpt-vocab

At runtime, SubMiner also searches these derived locations:

• vendor/yomitan-jlpt-vocab
• vendor/yomitan-jlpt-vocab/vendor/yomitan-jlpt-vocab
• vendor/yomitan-jlpt-vocab/yomitan-jlpt-vocab

and user-data/config fallback paths (see getJlptDictionarySearchPaths in src/main.ts).

Required files

The expected files are:

• term_meta_bank_1.json
• term_meta_bank_2.json
• term_meta_bank_3.json
• term_meta_bank_4.json
• term_meta_bank_5.json

Each bank maps terms to frequency metadata; only entries with a frequency.displayValue are considered for JLPT tagging.

SubMiner also reuses the same term_meta_bank_*.json format for frequency-based subtitle highlighting, using installed/default frequency-dictionary locations or an explicit subtitleStyle.frequencyDictionary.sourcePath.

Source and update process

For reproducible updates:

1. Obtain the JLPT term-meta bank archive from the same upstream source that supplies the bundled Yomitan dictionary data.
2. Extract the five term_meta_bank_*.json files.
3. Place them into vendor/yomitan-jlpt-vocab/.
4. Commit the update with the source URL/version in the task notes.

This repository currently ships the folder path in electron-builder extraResources as: vendor/yomitan-jlpt-vocab -> yomitan-jlpt-vocab.

Fallback Behavior

If bank files are missing, malformed, or lack expected metadata, SubMiner skips them gracefully. When no usable entries are found, JLPT underlining is silently disabled and subtitle rendering remains unchanged.
