# Wiki
|
||||||
|
|
||||||
|
This is a collection of notes. We use [Quartz](https://quartz.jzhao.xyz/) to
|
||||||
|
transform Markdown content into a statically generated site. Markdown files are
|
||||||
|
primarily managed with [Obsidian](https://obsidian.md/). To serve Quartz
|
||||||
|
locally, run the following:
|
||||||
|
```bash
|
||||||
|
$ npx quartz build --serve
|
||||||
|
```
|
||||||
|
By default the server will live at `localhost:8080`.
|
||||||
|
|
||||||
|
## Building
|
||||||
|
|
||||||
|
If you make changes to the `package-lock.json` file, you'll need to update the
|
||||||
|
`npmDepsHash` value in `flake.nix`. The easiest way to discover this value is
|
||||||
|
by running the following:
|
||||||
|
```bash
|
||||||
|
$ prefetch-npm-deps package-lock.json
|
||||||
|
```
|
||||||
|
Alternatively, you can set the value of `npmDepsHash` to `lib.fakeHash` and run:
|
||||||
|
```bash
|
||||||
|
$ nix build
|
||||||
|
```
|
||||||
|
Nix will complain with the hash value it actually expected.
|
||||||
|
|
||||||
|
## Language Server
|
||||||
|
|
||||||
|
The [typescript-language-server](https://github.com/typescript-language-server/typescript-language-server)
|
||||||
|
(version 4.1.2) is included in this flake.
|
||||||
|
|
||||||
|
## Formatting
|
||||||
|
|
||||||
|
Formatting depends on [prettier](https://prettier.io/) (version 3.1.0). A
|
||||||
|
`pre-commit` hook is included in `.githooks` that can be used to format all
|
||||||
|
`*.jsx?` and `*.tsx?` files prior to commit. Install via:
|
||||||
|
```bash
|
||||||
|
$ git config --local core.hooksPath .githooks/
|
||||||
|
```
|
||||||
|
If running [direnv](https://direnv.net/), this hook is installed automatically
|
||||||
|
when entering the directory.

An interesting point Robbins[^robbins] discusses in his introduction to [[gawk]] is this idea of command robustness. He states that:
|
||||||
|
|
||||||
|
> A self-contained shell script is more reliable because there are no other files to misplace.
|
||||||
|
|
||||||
|
%%ANKI
|
||||||
|
Basic
|
||||||
|
What is a self-contained shell script?
|
||||||
|
Back: A shell script that does not rely on the presence of other files.

||||||
|

The point he is arguing is that the first command below is considered more robust than the second since the command is more loosely coupled to its environment:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ awk 'program' input-file1 input-file2 ...
|
||||||
|
$ awk -f program-file input-file1 input-file2 ...
|
||||||
|
```
|
||||||
|
|
||||||
|
It's interesting to think what else can be used as a measure of a command's robustness:
|
||||||
|
|
||||||
|
* Required environment variables or environment variables formatted in a certain way
|
||||||
|
* `$PATH` needs to point to a specific location
|
||||||
|
* Whether the invoked program is present by default in a distribution or must be installed
|
||||||
|
* The ability to run with or without an associated TTY
|
||||||
|
* The ability to run with or without associated standard streams
|
||||||
|
* `stdout`, `stderr`, `stdin`
|
||||||
|
* How backwards compatible the invoked program is
|
||||||
|
* Version mismatch may silently cause the same invocation to fail
|
||||||
|
* Expected permissions
|
||||||
|
* EUID, read permissions on an input file, etc.
|
||||||
|
* Determinism of the program itself
|
||||||
|
* Does output rely entirely on input or can it make nondeterministic choices
|
||||||
|
* The amount of resources dedicated to the program
|
||||||
|
* Failure may occur if not enough memory is provided to the command
|
||||||
|
* Whether a program acts idempotently
|
||||||
|
* What happens if I run the command twice in a row?
|
||||||
|
* Whether a program acts atomically
|
||||||
|
* Is it possible intermediate files are left that affect subsequent runs?

The shebang (also writting shabang or sha-bang) is a magic character at the start of a script indicating what command should be run when invoking the script directly. It always begins with ASCII characters `#!`.[^mendel]

Some systems limit the length of interpreters to just 32 characters. A simple workaround when encountering this limitation is to introduce a symbolic link.

|
||||||
|
Back: By taking the first initials of the original three creators.

## Setup
|
||||||
|
|
||||||
|
Robbins[^robbins] suggests executing command `set +H` on [[bash]] startup to disable [[C]] shell-style command history.
|
||||||
|
|
||||||
|
## Usage
|
||||||
|
|
||||||
|
`awk` applies actions to lines matching specified patterns. In this way `awk` is said to be data-driven - we specify the lines `awk` should act on and `awk` is responsible for finding and acting on them. Instructions are provided via a **program**.
|
||||||
|
|
||||||
|
%%ANKI
|
||||||
|
Basic
|
||||||
|
What is the basic function of `awk`?
|
||||||
|
Back: To apply actions to lines matching specified patterns.
|
||||||
|
Reference: Robbins, Arnold D. “GAWK: Effective AWK Programming,” October 2023. [https://www.gnu.org/software/gawk/manual/gawk.pdf](https://www.gnu.org/software/gawk/manual/gawk.pdf)

|
<!--ID: 1706726911445-->
|
||||||
|
END%%
|
||||||
|
|
||||||
|
An `awk` program consists of **rules**, each made up by a **pattern** and **action**. For example:
|
||||||
|
|
||||||
|
```awk
|
||||||
|
BEGIN { print "hello world" }
|
||||||
|
pattern { action }
|
||||||
|
```
|
||||||
|
|
||||||
|
%%ANKI
|
||||||
|
Basic
|
||||||
|
An `awk` program consists of a series of what?
|
||||||
|
Back: Rules.
|
||||||

|
||||||

|

|
%%ANKI
|
||||||
|
Basic
|
||||||
|
A rule found in an `awk` program consists of what two parts?
|
||||||
|
Back: A pattern and an action.

A standalone `awk` program usually has what shebang?

* Spent time today getting FSRS enabled in Anki. I now have a separate "Obsidian" deck that I'll slowly be transferring cards over, with all cards generated from this project.
|
||||||
|
* Last night and continuing today, will also been migrating all my Zotero references to a new "Obsidian" collection. The goal is to be more mindful as to how I consume the content and create cards/take notes.
|
||||||
|
* Began working through "GAWK: Effective AWK Programming" by Arnold D. Robbins. This inspired some notes around shell commands and what it means for them to be [[robustness|robust]].
