[Docker proposal branch] Using one-line commands

[racterub]

With current commit 3505579, Docker will trigger error "Empty continuation lines will become errors in a future release." and stop building.

code:

python-mode/Dockerfile

Lines 23 to 28 in 3505579

	RUN set -ex \
	&& cd /opt \
	&& chmod +x build_vim.sh \
	&& git clone https://github.com/vim/vim.git \
	&& ./build_vim.sh ${PYTHON} \
	&& rm -rf vim build_vim.sh

python-mode/Dockerfile

Lines 36 to 43 in 3505579

	RUN set -ex \
	&& cd ${PYTHON_MODE_HOME} \
	&& find . -type f -name '*.pyc' -delete \
	&& find . -type d -name '__pycache__' -delete \
	&& ln -s ${PYTHON_MODE_HOME}tests/utils/test.py ${TEST_FILE} \
	&& ln -s ${PYTHON_MODE_HOME}tests/utils/pymoderc ${PYMODE_RC} \
	&& ln -s ${PYTHON_MODE_HOME}tests/utils/vimrc ${VIM_RC} \
	&& touch /root/.vimrc.before /root/.vimrc.after \

With my commit, everything works fine.

Hi @racterub Thanks for the PR!

Actually, the problem was just with line 43. There was an extra \ over there.

For maintenance purposes I think I prefer each command in a line (and it is ok, there is no warning with that!).

I've pushed the change. Can you try to see if the warning is still there?

Thanks!

If you mean docker, it works fine 😄

And, I'm thinking of putting a script on image for faster testing 😕
Which should look like this

root@847d2ab482e4:~# cat test.sh
#!/bin/bash

cd ~/.vim/pack/foo/start/python-mode
find . -type f -name '*.pyc' -delete && find . -type d -name '__pycache__' -delete
vim -i NONE -u debugvimrc.vim ~/test.py
