# `mix text.download_lemma_data`
[🔗](https://github.com/kipcole9/text/blob/v0.6.1/lib/mix/tasks/text.download_lemma_data.ex#L1)

Downloads lemmatization dictionaries from the
[`michmech/lemmatization-lists`](https://github.com/michmech/lemmatization-lists)
upstream and places them in the configured `Text.Data` cache so
`Text.Lemma` can load them with no further network access.

Useful when you don't want to enable
`config :text, auto_download_lemma_data: true` (which would let
the package fetch on first lookup) but still want the data
available locally — e.g. as a build step in CI, or to ship the
dictionary alongside a release.

Source data is licensed under the Open Database License (ODbL)
by Michal Boleslav Měchura. The download includes the upstream
license file alongside the per-language `.txt` files.

## Usage

    # Download a single language pack.
    mix text.download_lemma_data de

    # Download several at once.
    mix text.download_lemma_data de fr es it pt

    # List the languages this task knows about.
    mix text.download_lemma_data --list

## Options

* `--force` — re-downloads even when the file is already cached.

* `--list` — prints the language codes available upstream and
  exits without downloading anything.

## Where files land

Files are written to `Text.Data.data_dir()/lemma/lemmatization-<lang>.txt`,
by default `~/.cache/text/lemma/`. Override the cache location
with:

    config :text, data_dir: "/path/to/cache"
