command line interface - Yeoman Generator: CLI+File Instead of Prompt -

i've been using few yeoman generators prompt me user input. i'd prefer put inputs in json file though. can see yo-rc.json gets generated afterwards, i'd use (or file it) input yeoman.

example using jhipster:

current behavior

$ yo jhipster  welcome jhipster generator v2.16.1 ? (1/15) base name of application? (jhipster) helpme ? (2/15) default java package name? com.mycompany.helpme ...  # yeoman generator creates project via user inputs 

desired behavior

$ cat my-custom.json {   "generator-jhipster": {     "basename": "helpme",     "packagename": "com.mycompany.helpme",     ...  $ yo jhipster --file my-custom.json ...  # yeoman generator creates project via input file 

it sounds should able leverage yeoman storage api, haven't succeeded route, nor can find similar examples.

[edit] next steps

next wanted generate entities, unprompted, complex relationships per (https://jhipster.github.io/managing_relationships.html). found 2-step process:

1. create ./.jhipster/myentity.json
2. yo jhipster:entity myentity.json
3. profit

jhipster see comment on question. below jhipster reads .yo-rc.json, if want other name can done well, need read file using file api, suggest keep json named .yo-rc.json compatibility
