Docker Command Line Interface for RosaeNLG

This is the documentation for 1.9.1 version, which is not the latest version. Consider upgrading to 3.4.0.

Docker image for RosaeNLG that contains essentially RosaeNLG’s CLI. It does not contain any server.

It is essentially useful for:

developing RosaeNLG templates without bothering with installing node.js etc.: write templates in VSCode or any other editor and render them
package RosaeNLG templates in a JSON package before uploading them to a server

Be aware that your system needs to run docker, then node.js inside your container, then compile etc. etc. before rendering your templates: performance is poor compared when using RosaeNLG as a node.js library or in the browser.

First test

With fruits.pug on your local filesystem, with no dependancies (i.e. no include in your pug file):

- var data = ['apples', 'bananas', 'apricots', 'pears'];
p
  eachz fruit in data with { separator: ',', last_separator: 'and', begin_with_general: 'I love', end:'!' }
    | #{fruit}

cat fruits.pug | docker run -i registry.gitlab.com/rosaenlg-projects/rosaenlg/cli:latest -l en_US

You should obtain <p>I love apples, bananas, apricots and pears!</p>.

You can render continuously while you edit using the -w option.

Templates with includes

If your templates include other templates (using include - which is very common), you have to map filesystems so that the docker file can read the includes.

docker run -i -v /home/user/rosaenlg/local_templates/:/templates registry.gitlab.com/rosaenlg-projects/rosaenlg/cli:latest -l en_US /templates/your_template.pug

You can use -w, --watch to watch files for changes and automatically re-render.

Package templates

fruits.pug on your local filesystem:

p
  eachz fruit in data with { separator: ',', last_separator: 'and', begin_with_general: 'I love', end:'!' }
    | #{fruit}

packageOpts.json on your local filesystem (in the same folder as fruits.pug):

{
  "templateId": "fruits",
  "entryTemplate": "fruits.pug",
  "folderWithTemplates": "/templates",
  "compileInfo": {
    "activate": false,
    "language": "en_US"
  }
}

docker run -i -v /home/user/rosaenlg/local_templates/:/templates registry.gitlab.com/rosaenlg-projects/rosaenlg/cli:latest --jsonpackage --packageopts /templates/packageOpts.json

This should output a new JSON flow, packaged to be used in a RosaeNLG server:

{
  "templateId": "fruits",
  "entryTemplate": "fruits.pug",
  "compileInfo": {
    "language": "en_US"
  },
  "templates": {
    "fruits.pug": "* var data = ['apples', 'bananas', 'apricots', 'pears'];\np\n  eachz fruit in data with { separator: ',', last_separator: 'and', begin_with_general: 'I love', end:'!' }\n    | #{fruit}\n\n\n"
  }
}
