[Migration to v4] - Any ideas on how to automate manually adding #. js-lingui-explicit-id ?

[2snEM6]

Hi!

In our particular case, sometimes we use explicit ids and sometimes we don't. This means that we can't just set "explicitIdAsDefault" to true.

As per the docs, the way to go is to manually add #. js-lingui-explicit-id to every single translation entry that is extracted from an explicit ID. This is a very tedious job having a large catalog.

If we don't add the #. js-lingui-explicit-id , then the translations disappear and we need to translate everything again.

As a side note, if we add #. js-lingui-explicit-id, then translations are kept, but our translation provider (phrase.com) removes comments when translating the catalog via their UI. Is there any workaround for this? I guess many translation providers work this way, so it might be a problem to other people.

Thank you

I will try to prepare kind of migration path with script for that purpose.
In general you can do the following:

• Extract to template lingui extract-template
• In script read your template with a po-format
• read old translation file with po-format
• match strings from template with your translation
• add #. js-lingui-explicit-id using template as source of truth.

try this

// migrate.ts
import {
  CatalogType,
  ExtractedMessageType,
  getConfig,
  LinguiConfigNormalized,
  MessageType,
} from "@lingui/conf"

import { getCatalogs } from "@lingui/cli/api"
import { formatter as createFormatter } from "@lingui/format-po"
import fs from "fs/promises"
import { generateMessageId } from "@lingui/message-utils/generateMessageId"

function _isGeneratedId(id: string, message: ExtractedMessageType): boolean {
  return id === generateMessageId(message.message, message.context)
}

async function command(
  config: LinguiConfigNormalized,
) {
  const catalogs = await getCatalogs(config)

  const formatter = createFormatter({
    explicitIdAsDefault: true,
  })

  await Promise.all(
    catalogs.map(async (catalog) => {
      const extractedCatalog = await catalog.collect()

      for (const locale of config.locales) {
        const translationFileName = catalog.getFilename(locale)

        const translationCatalog = await formatter.parse(
          await fs.readFile(translationFileName, "utf-8"),
          {
            locale,
            sourceLocale: config.sourceLocale,
            filename: translationFileName,
          }
        )

        for (const messageId in extractedCatalog) {
          const extractedMessage = extractedCatalog[messageId]

          const isGeneratedId = _isGeneratedId(messageId, extractedMessage)
          const oldId = isGeneratedId ? extractedMessage.message : messageId

          if (translationCatalog[oldId]) {
            ;(extractedMessage as MessageType).translation =
              translationCatalog[oldId].translation
          }
        }

        await catalog.write(locale, extractedCatalog as CatalogType)
      }
    })
  )
}

command(getConfig())

# in the place where is your lingui.config is located
ts-node ./migrate.ts

Any feedback on this would be much appreciated, as i wanted to add this a separate command in a lingui cli.

Thank you! I will be taking a look next week. I will let you know my findings

Hi @2snEM6, have you had a chance to test it? We are waiting for feedback and would like to move forward with #1686

Hey, I've ran this script on 2 projects now, and it worked fine for me. Did strip the types tough to use it without ts-node, but that should't make any differences.

[andrii-bodnar]

@thekip let's merge the script?

[2snEM6]

Hi! Not yet sorry :( we had to reprioritise things at my company so we be migrating later this year.
