# NAME
App::Greple::xlate - translation support module for greple
# SYNOPSIS
greple -Mxlate -e ENGINE --xlate pattern target-file
greple -Mxlate::deepl --xlate pattern target-file
# VERSION
Version 0.29
# DESCRIPTION
**Greple** **xlate** module find desired text blocks and replace them by
the translated text. Currently DeepL (`deepl.pm`) and ChatGPT
(`gpt3.pm`) module are implemeted as a back-end engine.
If you want to translate normal text blocks in a document written in
the Perl's pod style, use **greple** command with `xlate::deepl` and
`perl` module like this:
greple -Mxlate::deepl -Mperl --pod --re '^(\w.*\n)+' --all foo.pm
In this command, pattern string `^(\w.*\n)+` means consecutive lines
starting with alpha-numeric letter. This command show the area to be
translated highlighted. Option **--all** is used to produce entire
text.
Then add `--xlate` option to translate the selected area. Then, it
will find the desired sections 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. Output format
can be specified by **--xlate-format** option.
If you want to translate entire text, use **--match-all** option. This
is a short-cut to specify the pattern `(?s).+` which matches entire
text.
# OPTIONS
- **--xlate**
- **--xlate-color**
- **--xlate-fold**
- **--xlate-fold-width**=_n_ (Default: 70)
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.
Option **--xlate** calls **--xlate-color** option with **--color=never**
option.
With **--xlate-fold** option, converted text is folded 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.
- **--xlate-engine**=_engine_
Specifies the translation engine to be used. If you specify the engine
module directly, such as `-Mxlate::deepl`, you do not need to use
this option.
- **--xlate-labor**
- **--xlabor**
Insted of calling translation engine, you are expected to work for.
After preparing text to be translated, they are copied to the
clipboard. You are expected to paste them to the form, copy the
result to the clipboard, and hit return.
- **--xlate-to** (Default: `EN-US`)
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**, **cm**
Original and converted text are printed 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**
Original and converted text are printed 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**
Original and converted text are printed separated by single blank
line.
- **xtxt**
If the format is `xtxt` (translated text) or unkown, only translated
text is printed.
- **--xlate-maxlen**=_chars_ (Default: 0)
Specify the maximum length of text to be sent to the API at once.
Default value is set as for free DeepL account service: 128K for the
API (**--xlate**) and 5000 for the clipboard interface
(**--xlate-labor**). You may be able to change these value if you are
using Pro service.
- **--**\[**no-**\]**xlate-progress** (Default: True)
See the tranlsation result in real time in the STDERR output.
- **--match-all**
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.
- --cache-clear
The **--cache-clear** option can be used to initiate cache management
or to refresh all existing cache data. Once executed with this option,
a new cache file will be created if one does not exist and then
automatically maintained afterward.
- --xlate-cache=_strategy_
- `auto` (Default)
Maintain the 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.
- `clear`
Clear the cache data first.
- `never`, `no`, `0`
Never use cache file even if it exists.
- `accumulate`
By default behavior, unused data is removed from the cache file. If
you don't want to remove them and keep in the file, use `accumulate`.
# COMMAND LINE INTERFACE
You can easily use this module from the command line by using the
`xlate` command included in the repository. See the `xlate` help
information for usage.
# EMACS
Load the `xlate.el` file included in the repository to use `xlate`
command from Emacs editor. `xlate-region` function translate the
given region. Default language is `EN-US` and you can specify
language invoking it with prefix argument.
# ENVIRONMENT

Set your authentication key for DeepL service.
- OPENAI\_API\_KEY
OpenAI authentication key.
