[![Actions Status](https://github.com/kaz-utashiro/App-Greple-xlate/actions/workflows/test.yml/badge.svg)](https://github.com/kaz-utashiro/App-Greple-xlate/actions) # NAME App::Greple::xlate - translation support module for greple # SYNOPSIS greple -Mxlate::deepl --xlate pattern target-file # DESCRIPTION **Greple** **xlate** module find text blocks and replace them by the translated text. Currently only DeepL service is supported by the **xlate::deepl** module. If you want to translate normal text block in [pod](https://metacpan.org/pod/pod) style document, use **greple** command with `xlate::deepl` and `perl` module like this: greple -Mxlate::deepl -Mperl --pod --re '^(\w.*\n)+' --all foo.pm Pattern `^(\w.*\n)+` means consecutive lines starting with alpha-numeric letter. This command show the area to be translated. Option **--all** is used to produce entire text.

Then add `--xlate` option to translate the selected area. It will find and replace them by the **deepl** command output. By default, original and translated text is printed in the "conflict marker" format compatible with [git(1)](http://man.he.net/man1/git). Using `ifdef` format, you can get desired part by [unifdef(1)](http://man.he.net/man1/unifdef) command easily. Format can be specified by **--xlate-format** option.

If you want to translate entire text, use **--match-entire** option. This is a short-cut to specify the pattern matches entire text `(?s).*`. # OPTIONS - **--xlate** - **--xlate-color** Invoke the translation process for each matched area. Without this option, **greple** behaves as a normal search command. So you can check which part of the file will be subject of the translation before invoking actual work. Command result goes to standard out, so redirect to file if necessary, or consider to use [App::Greple::update](https://metacpan.org/pod/App%3A%3AGreple%3A%3Aupdate) module. **--xlate** calls **--xlate-color** option with **--color=never** option. - **--xlate-engine**=_engine_ Specify the translation engine to be used. You don't have to use this option because module `xlate::deepl` declares it as `--xlate-engine=deepl`. - **--xlate-to** (Default: `JA`) Specify the target language. You can get available languages by `deepl languages` command when using **DeepL** engine. - **--xlate-format**=_format_ (Default: conflict) Specify the output format for original and translated text. - **conflict** Print original and translated text in [git(1)](http://man.he.net/man1/git) conflict marker format. <<<<<<< ORIGINAL original text ======= translated Japanese text >>>>>>> JA You can recover the original file by next [sed(1)](http://man.he.net/man1/sed) command. sed -e '/^<<<<<<< /d' -e '/^=======$/,/^>>>>>>> /d' - **ifdef** Print original and translated text in [cpp(1)](http://man.he.net/man1/cpp) `#ifdef` format. #ifdef ORIGINAL original text #endif #ifdef JA translated Japanese text #endif You can retrieve only Japanese text by the **unifdef** command: unifdef -UORIGINAL -DJA foo.ja.pm - **space** Print original and translated text separated by single blank line. - **none** If the format is `none` or unkown, only translated text is printed. - **--**\[**no-**\]**xlate-progress** (Default: True) See the tranlsation result in real time in the STDERR output. - **--xlate-fold** - **--xlate-fold-width**=_n_ (Default: 70) Fold converted text by the specified width. Default width is 70 and can be set by **--xlate-fold-width** option. Four columns are reserved for run-in operation, so each line could hold 74 characters at most. - **--match-entire** Set the whole text of the file as a target area. # CACHE OPTIONS **xlate** module can store cached text of translation for each file and read it before execution to eliminate the overhead of asking to server. With the default cache strategy `auto`, it maintains cache data only when the cache file exists for target file. If the corresponding cache file does not exist, it does not create it. - --xlate-cache=_strategy_ - `auto` (Default) Maintain cache file if it exists. - `create` Create empty cache file and exit. - `always`, `yes`, `1` Maintain cache anyway as far as the target is normal file. - `never`, `no`, `0` Never use cache file even if it exists. - `accumulate` By default behavior, unused data is removed from cache file. If you don't want to remove them and keep in the file, use `accumulate`. # ENVIRONMENT - DEEPL\_AUTH\_KEY Set your authentication key for DeepL service. # SEE ALSO - [https://github.com/DeepLcom/deepl-python](https://github.com/DeepLcom/deepl-python) DeepL Python library and CLI command. - [App::Greple](https://metacpan.org/pod/App%3A%3AGreple) See the **greple** manual for the detail about target text pattern. Use **--inside**, **--outside**, **--include**, **--exclude** options to limit the matching area. - [App::Greple::update](https://metacpan.org/pod/App%3A%3AGreple%3A%3Aupdate) You can use `-Mupdate` module to modify files by the result of **greple** command. - [App::sdif](https://metacpan.org/pod/App%3A%3Asdif) Use **sdif** to show conflict marker format side by side with **-V** option. # AUTHOR Kazumasa Utashiro # LICENSE Copyright ©︎ 2023 Kazumasa Utashiro.
