Not catching 'closing quotation' error

[Tomohare]

$ cat Dockerfile
FROM ubuntu

LABEL label1='A' \
      label2='B'@C' \
      label3='D'

RUN apt-get update -qq

$ pip install dockerfile-parse==0.0.10
$ python -c "from dockerfile_parse import DockerfileParser; dfp = DockerfileParser(); print(dfp.labels)"

result:

{u'label1': u'A', u'label2': u'B@C       label3=D'}

expected:

ValueError: No closing quotation

We are bug-compatible with Docker here.

$ cat Dockerfile 
FROM scratch
LABEL label1='A' \
      label2='B'@C' \
      label3='D'
$ docker build -t test .

I tried to use the same Dockerfile as you and got this message unexpected end of statement while looking for matching single-quote. Maybe you are using docker in a different version.

$ cat Dockerfile
FROM scratch

LABEL label1='A' \
      label2='B'@C' \
      label3='D'

$ docker --version
Docker version 18.03.1-ce, build 9ee9f40

$ docker build -t test .

Yes, indeed, it seems to be a change in behaviour.

$ docker --version
Docker version 1.13.1, build 1ab62f1-unsupported
