plan9port linux environment

Configurations, clients, scripts and guides to work with plan9ports in linux.

Because I always forgot to set up something, I just wanna clone this and be ready.

I just understood why /usr/local/plan9 is a good compromise. You just need to run plan9port on OSX, Linux and FreeBSD, and the easiest way to set up a profile which behaves as expected on the three systems is by using a hardcoded system path.

The NAMESPACE variable is something ugly too. I decided to create a $HOME/.ns/N direcotry as a namespace point. There is a funcion in the profile called nssetup N which creates folder in case it does not exists, and return the path created to set up the NAMESPACE variable.

Install

If you want to contribute to plan9port, it is convenient to clone the repository on your $HOME folder and then link that to /usr/local/plan9 so everything works.

% git clone https://github.com/9fans/plan9port.git $HOME/.local/plan9
% sudo ln -s $HOME/.local/plan9 /usr/local/plan9

I use ~/.local/plan9 instead of something like ~/src to remind myself I cannot left the tree broken, because I use it. But still I want to test things and make some changes.

Assets

Fonts

The getfonts.rc script downloads fonts and install them on your $HOME. These days I use IBM Plex family.

One caveat with fontsrv is that it does not support fallback fonts on Linux. It seems to work on OSX. If you need emoji support, you can use DejaVuSans which has a good UTF support including some emojis.

I have set up that font as default in the profile.

There are Three scripts to play with fonts inside acme:

• F+ → Increases the size of the current font, by 1 point or the number passed as argument

• F- → Decreases the size of the cuurrent font, by 1 point or the number passed as argument

• F → Sets the current font to be the one passed by argument. If the font is not found, it greps through the font list searching for the pattern passed by argument

Programming languages

I need to use a couple programming languages daily, so I build a couple of scripts to set up the environment for them. I prefer to manage these environments and versions carefully instead of installing system-wide environments.

The profile loads a lot of variables for each language.

• getgo.rc--> installs golang in $HOME/.local/go
• getjava.rc --> install java in $HOME/.local/java
• getscala.rc --> install metals and scalafmt into $HOME/.local/bin
• opam.rc --> install opam into $HOME/local/bin (beware this is a curl | bash)

Acme

I use acme-lsp to work with those programming languages sometimes.

• gopls --> golang language server
• jdt --> java language server (from eclipse)
• metals --> scala language server
• ocaml-lsp --> ocaml language server
• ccls --> C language server

And also xplor to naviage code in some projects with deep nested directories.

Factotum

I use factotum as a cheap password manager sometimes. For that I have created src/pass.c. It is probably insecure, but a better option that a plain text file laying araound or a complex password manager.

Email

I use nedmail and upas to read email. I have put some documentation in docs/p9p-email.md

There are some scripts I use in mail/ for reading and sending email using plan9ports programs.

Dekstop interface

Still trying to find something satisfactory. Just use whatever it is at hand for now.

There are too many things out there. Playing nice will them is too painfull. So I have removed all custom configurations and helpers to deal with graphical environment

I will let a way to launch 9term and acme with the plan9port profile loaded, like .dekstop files or BSDs and Linux.
