# ngx-translate-extract
|
|
Extract translatable (ngx-translate) strings and save as a JSON or Gettext pot file.
|
|
Merges with existing strings if the output file already exists.
|
|
|
|
## Usage
|
|
Install the package in your project:
|
|
|
|
`npm install @biesbjerg/ngx-translate-extract --save-dev`
|
|
|
|
Add an `extract` script to your project's `package.json`:
|
|
```
|
|
"scripts": {
|
|
"extract": "ngx-translate-extract --input ./src --output ./src/assets/i18n/*.json --clean --sort --format namespaced-json"
|
|
}
|
|
```
|
|
You can now run `npm run extract` to extract strings.
|
|
|
|
## Extract examples
|
|
|
|
**Extract from dir and save to file**
|
|
|
|
`ngx-translate-extract -i ./src -o ./src/i18n/strings.json`
|
|
|
|
**Extract from multiple dirs**
|
|
|
|
`ngx-translate-extract -i ./src/folder-a ./src/folder-b -o ./src/i18n/strings.json`
|
|
|
|
**Extract and save to multiple files**
|
|
|
|
`ngx-translate-extract -i ./src -o ./src/i18n/{da,en,fr}.json`
|
|
|
|
**or**
|
|
|
|
`ngx-translate-extract -i ./src -o ./src/i18n/da.json ./src/i18n/en.json ./src/i18n/fr.json`
|
|
|
|
**or (update only)**
|
|
|
|
`ngx-translate-extract -i ./src -o ./src/i18n/*.json`
|
|
|
|
**or (update only)**
|
|
|
|
## Custom indentation
|
|
By default, tabs are used for indentation when writing extracted strings to json formats:
|
|
|
|
`ngx-translate-extract -i ./src -o ./src/i18n/en.json --format-indentation $'\t'`
|
|
|
|
If you want to use spaces instead, you can do the following:
|
|
|
|
`ngx-translate-extract -i ./src -o ./src/i18n/en.json --format-indentation ' '`
|
|
|
|
## Mark strings for extraction using a marker function
|
|
If, for some reason, you want to extract strings not passed directly to TranslateService, you can wrap them in a custom marker function.
|
|
|
|
```ts
|
|
import { _ } from '@biesbjerg/ngx-translate-extract';
|
|
|
|
_('Extract me');
|
|
```
|
|
|
|
Add the `marker` argument when running the extract script:
|
|
|
|
`ngx-translate-extract ... -m _`
|
|
|
|
Modify the scripts arguments as required.
|
|
|
|
