Textmate and Perlbrew

Textmate is a marvelous text editor for programming and other text based tasks on OSX. It even has a great extension for assisting when programming Perl. One of the really helpful features is a syntax validation happening when a file is saved.

Take for example this incomplete Perl source file below

If you specify the contents as perl (see the bottom of the window) or let Textmate resolve this…

Hi Guys. I am on Centos 7 and installed a new version of Perl using PerlBrew so i can use a different version.

​

I am trying to install Virtualmin and run into the following issue.

Can't locate Virtualmin/Config.pm in @INC (you may need to install the Virtualmin:

:Config module) (@INC contains: /root/perl5/perlbrew/perls/perl-5.30.0/lib/site_perl/5.30.0/x86_64-linux /root/perl5/perlbrew/perls/perl-5.30.0/lib/site_perl/5.30.0 /root/perl5/perlbrew/perls/perl-5.30.0/lib/5.30.0/x86_64-linux /root/perl5/perlbrew/perls/perl-5.30.0/lib/5.30.0) at /usr/bin/virtualmin-config-system line 9.

Auto set perlbrew with bash and git

I've started using the lib feature of perlbrew with all of my perl projects. I create a local::lib for each project and switch using 'perlbrew use' accordingly.

The following bash script aliases 'cd' so that when I switch to a git directory the correct perlbrew lib is automatically set.

To accomplish this I set two custom git config parameters:

mydata.perlbrew.perl mydata.perlbrew.lib

If I want to use perl version 5.14.2 and a local::lib called 'myproject'

git config mydata.perlbrew.perl perl-5.14.2 git config mydata.perlbrew.lib myproject

I use git config mostly out of laziness. The git command already knows how to figure out when you are in a repository at any directory level so I save having to write that code in shell script.

Gist

function cd_func () { builtin cd "$@" wanted_perl=$(git config mydata.perlbrew.perl 2>/dev/null) if ([ -n "$wanted_perl" ]); then wanted_lib=$(git config mydata.perlbrew.lib 2>/dev/null) perlbrew_cmd="perlbrew use $wanted_perl@$wanted_lib" if ([ -n "$wanted_lib" ]); then if ([ -n "$PERLBREW_PERL" ] && [ -n "$PERLBREW_LIB" ]); then if [ $PERLBREW_PERL != $wanted_perl ] || [ $PERLBREW_LIB != $wanted_lib ]; then ${perlbrew_cmd} fi else ${perlbrew_cmd} fi fi elif ([ -n "$PERLBREW_PERL" ] && [ -n "$PERLBREW_LIB" ]); then perlbrew_cmd="perlbrew use perl-5.14.2@myperl" ${perlbrew_cmd} fi } alias cd=cd_func

You will notice that I have a base lib called 'myperl' that I switch to whenever I am not working in a Git repository. It will only set this value if PERLBREW_PERL and PERLBREW_LIB are not already set. This allows me to use perlbrew freely outside of git repositories.

Perlbrew を利用したプロダクション環境構築

2011.11.05 carton追記

2011.12.07 スクリプトに追加するPATHの記述を修正

2011.12.09 perlbrewのURL変更

Tips: 複数の案件が同居する "開発環境" では perlbrew lib 使うとライブラリパスを簡単に切り替えることができて便利だぞ！

アプリケーションユーザーを作成

# useradd app-user # cat /etc/passwd ... app-user:x:1001:1001::/home/app-user:/bin/bash # cat /etc/shadow ... app-user:!!:15266:0:99999:7:::

これで次のような状態のユーザーが作成されるぞ。

パスワード未設定

/home/app-user

/bin/bash

一般ユーザーの su は NG

SSH, Telnet でのログインも NG

app-user で環境構築

ユーザー app-user に変更して...

# su - app-user

perlbrew をインストールしてから...

$ curl -kL http://install.perlbrew.pl | bash $ echo 'source ~/perl5/perlbrew/etc/bashrc' >> ~/.bashrc $ source ~/.bashrc $ perlbrew list ...

cpanm をインストールして...

$ perlbrew install-cpanm

perl をインストールして有効化。

$ perlbrew available ... $ perlbrew install perl-<VERSION> ... $ perlbrew switch perl-><VERSION>

アプリケーションのデプロイ

でぷろい！cpanm --installdepsで依存モジュールをインストールするんだ！

carton

開発環境でcartonを使ってモジュール管理していた場合はアプリケーションパッケージにcarton.lockがあるはずだ。 この場合はcarton installで依存モジュールをインストールできるぞ！

cartonを使うと開発環境と同じバージョンのモジュールがインストールされる。 「コードは一切変更がないのにデプロイしたらエラーが出る」なんてことが少なくなると思うぞ。開発環境と本番環境で容易にモジュールのバージョンを合わせることができるんだ。

carton install するとデフォルトでは local/ にモジュールがインストールされる。 perlスクリプト内で use lib するか perl -Ilocal/lib などでライブラリパスを通すのを忘れちゃダメだぞ！

cartonはまだ開発中ということで今後に期待だ。はやくcarton bundleを使いたいぞ。

アプリケーション実行スクリプト(daemontools の run スクリプトなど)

最後に実行スクリプトに perlbrew でインストールした perl のパスを追加して完了だ。

PATHに追加するperlbrewと利用するperlのパスは $PERLBREW_ROOT, $PERLBREW_PERL で確認するんだ！

ちなみに現在perlbrewを使って使用しているperlのバスは $PERLBREW_ROOT/perls/$PERLBREW_PERL/bin だぞ！

... export PATH=/home/app-user/perl5/perlbrew/bin:/home/app-user/perl5/perlbrew/perls/perl-5.14.1/bin:${PATH} exec setuidgid app-user ...

German Perl Workshop 2013

German Perl Workshop 2013

This is one of those blogposts, that should have been written on the plane home or on the hotel during the conference, but with too much going on and a load of work upon returning to work, it got delayed. This is an all too common pattern for me.

Anyway to get on subject, I have just attended my first German Perl Workshopever. I decided to go when I saw it was in Berlin. Berlin is fairly close to…
