Enable autorandr with Nix home-manager. I discovered autorandr when looking
through the home-manager source code. I was hoping it would automatically
enable/disable my external monitor when I connect/disconnect my HDMI cable, but
it doesn't.
With autorandr, I run...
```shell
> autorandr --load mobile
```
...to load my randr settings for just my laptop without the external monitor,
and I run...
```shell
> autorandr --load docked
```
...to load my randr settings for my external monitor.
I'm not sure if this brings much more value than my existing display.el module,
but I'm willing to try it for now.
From what I understand, gLinux and Nix are sometimes compatible and sometimes
incompatible.
Some nix-installed programs rely on system state that differs from gLinux's
system state. In other cases, Google wraps existing programs (e.g. git) to
provide Google-specific configuration.
Ever since I switched to home-manager and set `programs.git.enable = true`,
magit, which uses the git that PATH exposes hasn't been able to push, fetch, and
a few other commands.
TODO(wpcarro): Define a base home.nix that my gLinux and NixOS machines can
extend.
Get all pstree outputs for a given process name.
Usage:
```fish
> ptree ssh-agent
```
I'm unsure if I like home-managers; I'd prefer defining this functions in a
functions.fish file for a few reasons:
- I like syntax highlighting.
- home-manager compiles this into poorly formatted fish code.
I removed the startup code from .profile. I also depend on a fork of
home-manager until I submit my PR from wpcarro/home-manager into
rycee/home-manager.
redshift didn't properly work because it couldn't read the DISPLAY environment
variable. I can fix this ad-hoc with `systemctl --user import-environment
DISPLAY`, but home-manager will do this automatically if I allow it to manage my
xsession.
If you haven't noticed, home-manager is managing increasingly more of my
configuration.
- Migrate session variables to home.nix
- Drop support for unused session variables like TERMINAL, VISUAL
I patched home-manager locally to support fzf keybindings for fish. I will PR
this into home-manager, but I haven't yet, which means that my home.nix file
depends on my local ~/home-manager.
