# The Personal Website of Jakob L. Kreuze

This repository contains the source code for my personal website. In particular:

- The Haunt configuration
- The Guile API server implementing all of the website's dynamic functionality
- Org source files for all of the articles published on the website

## Building

My website is, in theory, reproducible.
If you find that to not be the case, please let me know.

### Dependencies

- GNU Emacs `>= 29.3`
- GNU Guile `>= 2.2.7`
- `haunt == 0.2.4`
- `guile-commonmark >= 0.1.2`
- `guile-gcrypt >= 0.3.0`
- `guile-gnutls >= 3.7.8`
  - In Gentoo, this is `net-libs/gnutls` with `USE=guile`
- `guile-json >= 4.7.2`
- `git`
- `pagefind = 0.12.0` (optional)

### Website

When all of the dependencies have been installed, the website can be built by running `haunt build` from the directory this README file resides in.
When `haunt build` completes, the output will be at `site/`.
It may take a minute to fetch comments and webmentions.
The build process can be sped up by setting the `HAUNT_SKIP_COMMENTS` environment variable.
It may also take a few minutes to compile all of the posts using Emacs, but unless explicitly disabled, the results are cached.
Hence, subsequent builds will not take as long.

If using `pagefind`, the index will need to be build after running `haunt build`.
This can be done with `pagefind -s site/ -b _pagefind/`.

## Deploying

Recommend using `rsync -azv --delete --progress site/ [DESTINATION]` to update the static components on a remote.

The following OpenRC service will manage the API server:

```sh
#!/sbin/openrc-run

command="/usr/bin/guile"
command_args="-L ${JAKOB_API_DIR} ${JAKOB_API_DIR}/api.scm"
command_background=true
command_user="${JAKOB_API_USER}:${JAKOB_API_GROUP}"

pidfile="/run/${RC_SVCNAME}.pid"

depend() {
        need net
}
```

A sample `/etc/conf.d/jakob-api`:

```sh
JAKOB_API_DIR=/opt/jakob-api/
JAKOB_API_USER=jakob-api
JAKOB_API_GROUP=jakob-api
```

Ideas for a better name are appreciated 🙂

Before running the API server, the following databases will need to be created:

- `jakob_rsvp`
  - Initialized with `jakob/dynamic/schema-rsvp.sql`
- `jakob_gallery`
  - Initialized with `jakob/dynamic/schema-gallery.sql`
- `jakob_comments`
  - Initialized with `jakob/dynamic/schema-comments.sql`

### Dependencies

- GNU Guile `>= 2.2.7`
- `guile-gcrypt >= 0.3.0`
- `guile-json >= 4.7.2`
- `latex` and `dvipng`
- PostgreSQL `>= 14.0`

[squee](https://notabug.org/cwebber/guile-squee/) is currently vendored at `squee.scm`.

**TODO**: Should we package `squee` for Gentoo? Or use something more standard? I don't like vendoring code.

## API

Dynamic capabilities such as comments are implemented by the Guile API server (`api.scm`).
It is assumed that the web server proxies all requests matching a `/api` prefix to this server.
By default, the API server runs on port `8081`.

**TODO**: "By default" implies that it's configurable without modifying the source code. It should be configurable. That shouldn't be a hard lift.

### Comments

#### Proof of Work

Used to generate a transient proof-of-work challenge.

**URL** : `/api/challenge/proof-of-work`

**Method** : `GET`

**Auth required** : NO

**Data constraints** : NONE

##### Success Response

**Code** : `200 OK`

**Content example**

```json
{
    "hardness": 4,
    "challenge-id": 621,
    "nonce": "pXdoMbxdsmz7zK86MbyLF3qnDVBiPgIy9TY7Optnnow="
}
```

#### Normal Captcha

Used to generate a visual (math problem) captcha challenge.

**URL** : `/api/challenge/captcha`

**Method** : `GET`

**Auth required** : NO

**Data constraints** : NONE

##### Success Response

**Code** : `200 OK`

**Content example**

```json
{
    "challenge-id": 263,
    "image": "data:image/jpeg;charset=utf-8;base64,[...]"
}
```

#### Post Comment

Used to generate a visual (math problem) captcha challenge.

**URL** : `/api/comment`

**Method** : `POST`

**Auth required** : NO

**Data constraints**

Data should be `application/x-www-form-urlencoded`.

- `slug`: identifier for the post being commented on.
- `name`: author name for comment.
- `comment`: markdown string containing comment content.
- `captcha-id`: `challenge-id` for captcha challenge.
- `captcha`: solution for captcha with identifier `challenge-id`.
- `subject` (optional): subject string of comment.
- `email` (optional): email address of author.
- `url` (optional): homepage of author.

`captcha-id` and the captcha challenge can be generated with the "Proof of Work" or "Normal Captcha" endpoints.
If the captcha was created by the former endpoint, then the field names are `captcha-alt` and `captcha-alt-id`.

##### Success Response

**Code** : `307 Temporary Redirect`

**Content example**

```json
{
    "success": true,
}
```
