Magento2: Translations export error [DomainException] Missed Phrase

[akamura]

Preconditions

1. Magento 2.1.0

Steps to reproduce

1. Login to SSH
2. Switch to user who own Magento directory rights
3. cd /var/html/magento/bin
4. php magento i18n:collect-phrases -o "/var/html/magento/translation_export.csv" -m

Expected result

1. Export the CSV file with English base translations to allow me to translate them in my own language.

Actual result

1. DomainException Missed Phrase

Unfortunately is really hard from the output to understand what file is blocking the export, I have also checked the log folder (var/log) but there is no trace of this error.

I'm getting 'Dictionary successfully processed.' on clean magento. Problem must be in your language pack. Try add '-vvv' option to see broken file.

[akamura]

@sevos1984 thanks for the suggestion, I tried adding -vvv and this is the result

[DomainException]
Missed phrase

I've recreated your issue, it occurs when you have empty strings for translation (e.g 'note' => __('')).

[akamura]

Ah, so perhaps somewhere in the template I have empty translation strings? There is a command to output the file containing empty strings? Thanks

[sevos1984]

Yes, check your templates. No there is no such command.

[akamura]

@sevos1984 thank you very much for the suggestion infact there was a missing translation that I found, now the export works correctly, I close this post as solved.

[gediminaskv]

Hello, I have the same issue. Where I can find "empty strings" ? No translations where done, so, from where those empty strings come?
Anyway, it's quite a strange thing because very first time when I ran collect-phrases everything was fine, but now it shows "missed phrase"...

[benheart]

@gediminaskv Maybe you can modify setup/src/Magento/Setup/Module/I18n/Dictionary/Phrase.php file, and comment the DomainException in setPhrase() and setTranslation() methods like this:

    public function setPhrase($phrase)
    {
        if (!$phrase) {
//            throw new \DomainException('Missed phrase');
            $this->_phrase = 'Missed phrase';
        } else {
            $this->_phrase = $phrase;
        }
    }

    public function setTranslation($translation)
    {
        if (!$translation) {
//            throw new \DomainException('Missed translation');
            $this->_translation = 'Missed translation';
        } else {
            $this->_translation = $translation;
        }
    }

And this will create .csv successfully, what's more, you can find the module of the "empty strings".

__('0'); also fails.

[webspeaks]

Magento should be able to handle empty phrases. I dont understand why do they not handle such small things.
Such issues cause developers to loose many hours.

[GuiltyNL]

Agreed with @webspeaks tranlating is already a pain in M2, this makes it even worse.

[GuiltyNL]

Err I did not unassign @sevos1984 ?

[c1gee]

Yes, check your templates. No there is no such command.

There is no such command but there is a search that works

Run this in your root folder to find all of the missing / empty strings

grep -rnw . -e "__('')" -e '__("")'

I have used this successfully several times.

I also like to email the plugin providers to let them know when they have missed a couple.
