Perl

plenvsetup v0.06 has been released

Let’s setup your own perl environment without system-perl

Today I released plenvsetup v0.06. plenvsetup is a quick setup tool for perl environment with plenv.

In the latest version, plenvsetup uses Shoichi Kaji(skaji)‘s perl-install instead of Perl-Build. This allows, we can install perl without system-perl under plenv.

Now we can use new plenvsetup with following one-liner.

1
$ curl -sL https://is.gd/plenvsetup | bash

You may zsh instead of bash.

Build on a Docker container

plenvsetup works on a Docker container it based on latest alpine linux image too.

For example, following Dockerfile setups the perl-5.30.0 with plenvsetup on container.

FROM alpine  
WORKDIR /root  
  
### install required dependencies (perl not required!)  
RUN apk add bash libc-dev gcc make patch git curl  
  
### download plenvsetup  
RUN curl -sL https://is.gd/plenvsetup > plenvsetup && chmod +x plenvsetup  
  
### use plenvsetup on bash  
ENV SHELL=/bin/bash  
RUN bash plenvsetup  
  
### install perl-5.30.0 with plenv  
RUN .plenv/bin/plenv install 5.30.0  
RUN .plenv/bin/plenv global 5.30.0  
RUN .plenv/bin/plenv rehash  
  
CMD /bin/bash

Then, you can build the Dockerfile, and run perl-5.30.0 within the container.
