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 0.3201

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 implemented as a back-end engine. Experimental support for gpt-4 is also included.

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). Using ifdef format, you can get desired part by unifdef(1) 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.

Conflict marker format data can be viewed in side-by-side style by sdif command with -V option. Since it makes no sense to compare on a per-string basis, the --no-cdif option is recommended. If you do not need to color the text, specify --no-textcolor (or --no-tc).

sdif -V --no-tc --no-cdif data_shishin.deepl-EN-US.cm

NORMALIZATION

Processing is done in specified units, but in the case of a sequence of multiple lines of non-empty text, they are converted together into a single line. This operation is performed as follows:

  • Remove white space at the beginning and end of each line.

  • If a line ends with a full-width character and the next line begins with a full-width character, concatenate the lines.

  • If either the end or the beginning of a line is not a full-width character, concatenate them by inserting a space character.

Cache data is managed based on the normalized text, so even if modifications are made that do not affect the normalization results, the cached translation data will still be effective.

This normalization process is performed only for the first (0th) and even-numbered pattern. Thus, if two patterns are specified as follows, the text matching the first pattern will be processed after normalization, and no normalization process will be performed on the text matching the second pattern.

greple Mxlate -E normalized -E not-normalized

Therefore, use the first pattern for text that is to be processed by combining multiple lines into a single line, and use the second pattern for pre-formatted text. If there is no text to match in the first pattern, then a pattern that does not match anything, such as (?!).

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 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

Instead 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) conflict marker format.

<<<<<<< ORIGINAL
original text
=======
translated Japanese text
>>>>>>> JA

You can recover the original file by next sed(1) command.

sed -e '/^<<<<<<< /d' -e '/^=======$/,/^>>>>>>> /d'
ifdef

Original and converted text are printed in cpp(1) #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 distribution. See the xlate help information for usage.

The xlate command works in concert with the Docker environment, so even if you do not have anything installed on hand, you can use it as long as Docker is available. Use -D or -C option.

Also, since makefiles for various document styles are provided, translation into other languages is possible without special specification. Use -M option.

You can also combine the Docker and make options so that you can run make in a Docker environment.

Running like xlate -GC will launch a shell with the current working git repository mounted.
