Kako smo ponudili 50 jezika
Kad smo krenuli u izradu naše web stranice GoHugo.io na više jezika, željeli smo učinkovit, skalabilan i isplativ način za generiranje prijevoda. Umjesto ručnog prevođenja svake stranice, iskoristili smo OpenAI API za automatizaciju procesa. Ovaj članak vodi vas kroz integraciju OpenAI API-ja s Hugom, koristeći HugoPlate temu iz Zeon Studija, kako bismo brzo i točno generirali prijevode.
Zašto smo odabrali OpenAI API za prijevod
Tradicionalne usluge prijevoda često zahtijevaju znatan ručni rad, a automatizirani alati poput Google Translatea, iako korisni, ne pružaju uvijek razinu prilagodbe koja nam je trebala. OpenAI API nam je omogućio da:
- Automatiziramo prijevode u velikom obujmu
- Prilagodimo stil prijevoda
- Održavamo bolju kontrolu kvalitete
- Besprijekorno integriramo s našom web stranicom baziranom na Hugu
- Označimo pojedine stranice za ponovno prevođenje
- Dodamo nove jezike uz minimalan trud
Korak po korak
1. Priprema Hugo web stranice
Naša stranica već je bila postavljena koristeći HugoPlate temu, koja podržava funkcionalnost više jezika. Prvi korak bio je omogućiti podršku za jezike u našem Hugo config/_default/languages.toml datoteci:
```toml
################ English language ##################
[en]
languageName = "English"
languageCode = "en-us"
contentDir = "content/english"
weight = 1
################ Arabic language ##################
[ar]
languageName = "العربية"
languageCode = "ar"
contentDir = "content/arabic"
languageDirection = 'rtl'
weight = 2
```
Ova konfiguracija osigurava da Hugo može generirati zasebne jezične verzije našeg sadržaja.
2. Automatizacija prijevoda s OpenAI API-jem
Razvili smo Bash skriptu za automatizaciju prevođenja Markdown datoteka. Skripta:
- Čita engleske
.mddatoteke iz izvornog direktorija. - Koristi OpenAI API za prevođenje teksta uz očuvanje Markdown formata.
- Zapisuje prevedeni sadržaj u odgovarajuće jezične direktorije.
- Prati status prijevoda koristeći JSON datoteku.
Evo naše bash skripte za automatizaciju prijevoda. Slobodno je koristite i prilagodite svojim potrebama:

# sequentially (one file at a time). It updates a JSON status file after processing each file.
# At the end of the run, it checks translation_status.json and removes any language from

3. Upravljanje statusom prijevoda
Kako bismo spriječili nepotrebne prijevode i pratili napredak, koristili smo JSON datoteku (translation_status.json). Skripta ažurira ovu datoteku nakon obrade svakog dokumenta, osiguravajući da se prevode samo novi ili ažurirani sadržaji.
4. Rukovanje pogreškama i ograničenjima API-ja
Implementirali smo ponovne pokušaje i rukovanje pogreškama za slučajeve ograničenja brzine, neuspjeha API-ja i problema s kvotama. Skripta čeka prije ponovnog pokušaja ako OpenAI API vrati grešku poput rate_limit_reached ili service_unavailable.
5. Deploy
Nakon što je prevedeni sadržaj generiran, pokretanjem hugo --minify gradi se višelingvalna statička stranica, spremna za objavu.
Izazovi i rješenja
1. Točnost prijevoda
Iako su prijevodi OpenAI-ja uglavnom točni, neki tehnički termini mogu zahtijevati ručni pregled, no budući da smo tim od dvoje, nadamo se najboljem. Fino smo podešavali upite kako bismo održali kontekst i ton.
2. Problemi s formatiranjem
Markdown sintaksa ponekad bi se promijenila u prijevodu. Kako bismo to popravili, dodali smo logiku postprocesiranja za očuvanje formatiranja.
3. Optimizacija troškova API-ja
Kako bismo smanjili troškove, implementirali smo keširanje da izbjegnemo ponovno prevođenje nepromijenjenog sadržaja.
4. Učinkovito ponovno prevođenje
Za ponovno prevođenje određenih stranica dodali smo parametar retranslate: true u front matter. Skripta ponovno prevodi samo stranice označene ovim parametrom. To nam omogućuje ažuriranje prijevoda po potrebi bez ponovnog prevođenja cijele stranice.
Zaključak
Integracijom OpenAI API-ja s Hugom automatizirali smo prijevod naše web stranice uz održavanje kvalitete i fleksibilnosti. Ovaj pristup uštedio je vrijeme, osigurao dosljednost i omogućio nam jednostavno skaliranje. Ako želite svoju Hugo stranicu učiniti višelingvalnom, OpenAI API nudi moćno rješenje.
