irregular symbols happens when translate docker yaml file

[tyhtao1990]

I tried to read a docker file as a template in my program, and replace the detail when new condition happens.but it failed when I use dump function.
My code is like:

let yaml  = require('js-yaml');
let filePath = **/docker-compos-template.yaml';
let savePath = '**/docker-compose-save.yaml';
try{
        let doc = yaml.safeLoad(fs.readFileSync(filePath),'utf8');
        console.log(doc);
        fs.writeFileSync(savePath, yaml.dump(doc), 'utf8');
 }catch(e) {
        console.log(e);
    }

My part of my template file is ：

 environment:
      - FABRIC_CA_HOME=/etc/hyperledger/fabric-ca-server
      - FABRIC_CA_SERVER_CA_NAME=ca-santai
      - CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=chembean_default
      - FABRIC_CA_SERVER_TLS_ENABLED=true
      - FABRIC_CA_SERVER_TLS_CERTFILE=/etc/hyperledger/fabric-ca-server-config/ca.santai.chembean.io-cert.pem

and the translated file is:

    environment:
      - FABRIC_CA_HOME=/etc/hyperledger/fabric-ca-server
      - FABRIC_CA_SERVER_CA_NAME=ca-santai
      - CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=chembean_default
      - FABRIC_CA_SERVER_TLS_ENABLED=true
      - >-
        FABRIC_CA_SERVER_TLS_CERTFILE=/etc/hyperledger/fabric-ca-server-config/ca.santai.chembean.io-cert.pem

the symbol >- is not defined in the template.
and then will be '' in translate files.
e.g my template file is:

environment:
      - CORE_LEDGER_STATE_STATEDATABASE=CouchDB
      - CORE_LEDGER_STATE_COUCHDBCONFIG_COUCHDBADDRESS=couchdb-santai:5984
    
      - CORE_PEER_ID=peer0.santai.chembean.io
      - CORE_PEER_NETWORKID=chembean
      - CORE_PEER_ADDRESS=peer0.santai.chembean.io:7051
      - CORE_PEER_GOSSIP_BOOTSTRAP=peer0.santai.chembean.io:7051
      - CORE_PEER_ADDRESSAUTODETECT=true
      - CORE_PEER_CHAINCODEADDRESS=peer0.santai.chembean.io:7052
      - CORE_PEER_CHAINCODELISTENADDRESS=0.0.0.0:7052
      - CORE_CHAINCODE_STARTUPTIMEOUT=1200s
      - CORE_PEER_GOSSIP_EXTERNALENDPOINT=peer0.santai.chembean.io:7051
      - CORE_PEER_LOCALMSPID=SantaiMSP
      - CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock
      # the following setting starts chaincode containers on the same
      # bridge network as the peers
      # https://docs.docker.com/compose/networking/
      - CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=chembean_default
      - CORE_LOGGING_LEVEL=INFO
      #- CORE_LOGGING_LEVEL=DEBUG
      - CORE_PEER_TLS_ENABLED=true
      - CORE_PEER_GOSSIP_USELEADERELECTION=true
      - CORE_PEER_GOSSIP_ORGLEADER=false
      - CORE_PEER_PROFILE_ENABLED=true
      - CORE_PEER_TLS_CERT_FILE=/etc/hyperledger/fabric/tls/server.crt
      - CORE_PEER_TLS_KEY_FILE=/etc/hyperledger/fabric/tls/server.key
      - CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/fabric/tls/ca.crt

but the translate file is:

    environment:
      - CORE_LEDGER_STATE_STATEDATABASE=CouchDB
      - 'CORE_LEDGER_STATE_COUCHDBCONFIG_COUCHDBADDRESS=couchdb-santai:5984'
      - CORE_PEER_ID=peer0.santai.chembean.io
      - CORE_PEER_NETWORKID=chembean
      - 'CORE_PEER_ADDRESS=peer0.santai.chembean.io:7051'
      - 'CORE_PEER_GOSSIP_BOOTSTRAP=peer0.santai.chembean.io:7051'
      - CORE_PEER_ADDRESSAUTODETECT=true
      - 'CORE_PEER_CHAINCODEADDRESS=peer0.santai.chembean.io:7052'
      - 'CORE_PEER_CHAINCODELISTENADDRESS=0.0.0.0:7052'
      - CORE_CHAINCODE_STARTUPTIMEOUT=1200s
      - 'CORE_PEER_GOSSIP_EXTERNALENDPOINT=peer0.santai.chembean.io:7051'
      - CORE_PEER_LOCALMSPID=SantaiMSP
      - 'CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock'
      - CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=chembean_default
      - CORE_LOGGING_LEVEL=INFO
      - CORE_PEER_TLS_ENABLED=true
      - CORE_PEER_GOSSIP_USELEADERELECTION=true
      - CORE_PEER_GOSSIP_ORGLEADER=false
      - CORE_PEER_PROFILE_ENABLED=true
      - CORE_PEER_TLS_CERT_FILE=/etc/hyperledger/fabric/tls/server.crt
      - CORE_PEER_TLS_KEY_FILE=/etc/hyperledger/fabric/tls/server.key
      - CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/fabric/tls/ca.crt

it seems that the symbol '' appears randomly.
Is there any good idea to help me solve these problems?

Quoting appears only when required. Result is correct and have no mistales.

There was attempt #454 to add option to force quatin, but implementation was far from perfect to accept.
