I'm currently quite unfamiliar with golang. As an exercise to help me onboard
onto golang, and as a proof-of-concept to see if golang is a viable substitute
for Python as a scripting language, I decided to port my delete_dotfile_symlinks
to golang.
In the process, renamed ./python -> ./scripts, which is a more accommodating
name for a directory.
I decided to start writing go code for scripts instead of python. I think this
will be a learning opportunity for me and should increase the integrity of my
scripts by adding some static type checking.
I think the name deploy is more representative of the purpose of this directory
since docker is just one of a few tools that I'm using to deploy software.
Renaming my mono-repo briefcase.
I first introduced this commit in master, but it introduced a bug where one of
two things would happen:
1. Emacs wouldn't start and would crash X.
2. Emacs would start but my keyboard wouldn't work.
I learned some valuable debugging skills in the process. Here are some of them:
When my keyboard was broken, I wanted to control my computer using my
laptop. Thankfully this is possible by using `x2x`, which forward X events from
the SSH client to the SSH host.
```shell
> # I'm unsure if this is the *exact* command
> ssh -X desktop x2x -west :0.0
```
Git commit-local bisecting. I didn't need to do a `git bisect` because I knew
which commit introduced the bug; it was HEAD, master. But -- as you can see from
the size of this commit -- there are many changes involved. I wanted to binary
search through the changes, so I did the following workflow using `magit`:
- git reset --soft HEAD^
- git stash 1/2 of the files changed
- re-run `nix-env -f ~/briefcase/emacs -i`
- restart X session
- If the problem persists, the bug exists in the non-stashed files. Repeat the
process until you find the bug.
In my case, the bug was pretty benign. Calling `(exwm/switch "Dotfiles")` at the
bottom of `window-manager.el` was failing because "Dotfiles" is the name of a
non-existent workspace; it should've been `(exwm/switch "Briefcase")`.
There may have been more problems. I changed a few other things along the way,
including exposing the env vars BRIEFCASE to `wpcarros-emacs` inside of
`emacs/default.nix`.
The important part is that this was a valuable learning opportunity, and I'm
glad that I'm walking away from the two days of "lost productivity" feeling
actually productive.
I'm using a Makefile until I can remember the command:
```shell
> nix-env -f . -i
```
This will install (i.e. `-i`) any derivations instantiated from the Nix
expression resolvable by `-f`. Ideally the incantation will look something like
this:
```shell
> nix-env -f '<universe>' -iA emacs
```
Informing `nix-env` to install all of the derivations created by the expression
at attribute `emacs` in my `<universe>` repository. For now two things are
preventing this:
1. `emacs` isn't an attribute in my top-level expression defined in the
`default.nix`.
2. If I do add `emacs` as an attribute and call the above command, my usage of
`readTree` results in `pkgs` missing `.lib` and a few other stdlib commands
that are available in `(import <nixpkgs> {})`.
A fix for both of these should be forthcoming.
At the moment, all of the Nix repositories that I'm consuming exist in ~. To
keep things consistent, I ran:
```shell
> hub clone nixos/nixpkgs ~/nixpkgs
```
When I first moved to London, I created common.txt to store the address of my
office, my temporary housing, my new phone number, and other information. It
serverd its purpose, but I no longer need it anymore.
bookmarks.txt started out as a dmenu/rofi -> google-chrome integration. This
predates EXWM, which has replaced this with a google-chrome.el module (or
something similarly named).
Manually merging:
- README.md: I added the description from universe/README.md into the heading of
dotfiles/README.md.
- .envrc: dotfiles/.envrc was a superset of universe/.envrc
- .gitignore: Adding some of the ignored patterns from universe/.gitignore to
dotfiles/.gitignore
Everything else here should be a simple rename.
I've been using Fish consistently for about a month now, and I don't see myself
switching back to ZSH. Some of the code from this commit should be published. I
may get around to that one day. Before I did that, I would need to clean it up
and document it, which I won't be doing today.
Thank you, ZSH, for your service.
I recently changed my hostname for my desktop and laptop from
wpcarro.lon.corp.google.com -> zeno.lon.corp.google.com
wpcarro2 -> seneca
If you're curious, the names Zeno and Seneca come from famous Stoic
philosophers. As you can see from this commit, my configuration depends on the
values of these hostnames.
Immediately impacted:
- .profile
- device.el
Not immediately impacted:
- configs/install
- configs/uninstall
- .ssh/config
- .zshrc*
* As a side note, I should stop supporting ZSH.
Using an .envrc file helps me DRY up some of my configuration. Ideally I should
only need to make changes to the .envrc file and then expect everything to work
as expected. Let's see how that goes.
Adding a README including my current method for deploying. See the README for
more details. All of this is quite virgin and as such is subject to change.
Using <depot>'s gemma project with `dockerTools.buildLayeredImage` because I
need access to a nix-packaged server and gemma is the first thing that comes to
mind.
I'm attempting to setup my blog using the following:
- Google Cloud Run: I whitelist a docker image that packages my application and
then Google runs it "statelessly" (i.e. without persistence). The stateless part
should be fine for the time being.
- Nix: Using `<nixpkgs>.dockerTools.buildLayeredImage` to output docker images
from Nix expressions.
- Docker: Upload the output image from the Nix expressions and upload it to
Google Container Registry from which it can be run from Google Cloud Run.
Some helpful commands:
```shell
> sudo gcloud auth login
> nix-build ./docker/cloud_run.nix
> sudo docker image import ./result
> sudo docker tag <name> gcr.io/<google-cloud-project-id>/<name>:<tag>
> sudo docker push gcr.io/<google-cloud-project-id>/<name>:<tag>
```
I'm unsure if Google Cloud Run is my desired end goal, but it may help me
publish a blog faster than setting up a Kubernetes cluster, which is what I'd
ultimately like to do. Cloud Run should be cheaper financially and time-wise.
A Poem:
I wanted to try out this package...
30 minutes later after a dozen failed attempts at packaging it...
I no longer want to try this package...
for now.
Update code that depends on my mono-repo being named "mono". I've renamed it to
"universe", which explains the changes in this commit.
TODO: Merge dotfiles into universe.
I'm having trouble debugging why `pgrep emacs` returns two PIDs instead of just
one. Additionally when I call `emacsclient .` on the command line, I see a
message...
"Waiting for Emacs..."
...but when I cycle through all of my workspaces, I don't see any active
buffers. This commit is part of a larger debugging effort to get this working as
expected.
The end goal is to have some functions that help me manage my Monzo and YNAB
accounts. YNAB (i.e. youneedabudget.com) doesn't support Monzo
integrations. However, both services offer APIs. Here I'm sketching ideas for
what the API integrations might look like. Coming soon: monzo.el.
Not adding it as a top-level dependency since maybe.el depends on on
prelude.el. This shouldn't be a circular dependency when the requirement happens
in the function's scope though.
Remove `dbus-launch` and prefer simply `exec emacs`. Add `--no-site-file` and
`--no-site-lisp` flags.
Temporarily disable `google-stuff.el` because it's unavailable with the
`--no-site-lisp` flag.
This should all be fixed when I fully nixify my Emacs.
Why?
- `company-mode` is too noisy in IRC buffers.
- `auto-fill-mode` inserts newline characters that end up each being their own
message, which means that I make more noise than I should in IRC.
Wrapping the `nix eval` incantation in a fish function for two reasons:
1. Document that this is how to evaluate Nix from a file.
2. Provide a more ergonomic way of evaluating Nix from a file.
This takes care of my outstanding TODO of understanding why something ivy was
being used and other times it wasn't. It turns out that there is a generic
`completing-read` function that many Emacs packages consume. `ivy-mode` ensures
that when that function is called it is used instead of the default Emacs
completing package.
I'm still unsure of the difference between ivy and counsel. My best guess
currently is that counsel is the narrowing framework and ivy is the integration
of the narrowing framework with `completing-read`. Swiper must be the
integration with incremental {forward,backward} search.
The previous commit that adds Java code is part of a larger project intended to
use Nix to package Clojure. I'd like to build something similar to @tazjin's
buildLisp except for Clojure instead of for Common Lisp. Once building for both
ecosystems is similarly easy, it will be easier for me to compare the two
languages. Right now `buildLisp` is so good that it attracts me to Common Lisp
even when I don't know the language.
Add an example of two java files, Main.java and Another.java, where Main.java
depends on Another.java. This is part of a larger example of attempting to use
Nix to package these.
Also ignoring the *.class files that `javac <filename>` outputs.
Removing the default.nix that I used to attempt to build prove, a Common Lisp
unit testing library. Also removing the lisp module with the unit tests
themselves.
`dired-display-file` opens the file in another window but does not focus that
window. `dired-find-file-other-window` does what `dired-display-file` does
except it focuses that window.
This function builds a version of SBCL using `nix.buildLisp` and points `sly` to
the built executable. The result is a REPL with access to your project's
dependencies, which is quite useful. One drawback at the moment is that if new
dependencies are added to the project, I think I need to rebuild SBCL using nix
and restart sly.
After some toil, I have a working proof-of-concept blog. The idea is simple:
write blog posts in markdown and store the posts in the `./posts`
directory. Then use the server and `pandoc` to convert these markdown files into
HTML at request time. I'm using nix to package everything together. It's far
from perfect, but it works at the moment, which is encouraging.
