-# Building bingus-blog
-
-this guide assumes you have git and are on linux.  
-at the moment, compiling on windows is supported, but not _for windows_.
-
-1. first, acquire _rust nightly_.  
-   the recommended method is to install [rustup](https://rustup.rs/),
-   and use that to get _rust nightly_. choose "customize installation",
-   and set "default toolchain" to nightly to save time later, provided
-   you do not need _rust stable_ for something else
-2. start your favorite terminal
-3. then, download the repository: `git clone https://git.slonk.ing/slonk/bingus-blog && cd bingus-blog`
-4. finally, build the application: `cargo +nightly build --release`
-5. your executable is `target/release/bingus-blog`, copy it to your server and
-   you're done!
-
-## Building for another architecture
-
-you can use the `--target` flag in `cargo build` for this purpose.  
-examples are for Arch Linux x86_64.
-
-here's how to compile for `aarch64-unknown-linux-gnu`
-(eg. Oracle CI Free Tier ARM VPS):
-
-```sh
-# install the required packages to compile and link aarch64 binaries
-sudo pacman -S aarch64-linux-gnu-gcc
-cargo +nightly build --release --target=aarch64-unknown-linux-gnu
-```
-
-your executable will be `target/aarch64-unkown-linux-gnu/release/bingus-blog`.
-
---
-
-a more tricky example is building for `aarch64-unknown-linux-musl`
-(eg. a Redmi 5 Plus running postmarketOS):
-
-```sh
-# there is no toolchain for aarch64-unknown-linux-musl,
-# so we have to repurpose the GNU toolchain. this doesn't
-# work out of the box so we have to set some environment variables
-sudo pacman -S aarch64-linux-gnu-gcc
-export CC=aarch64-linux-gnu-gcc
-export CARGO_TARGET_AARCH64_UNKNOWN_LINUX_MUSL_LINKER=$CC
-cargo +nightly build --release --target=aarch64-unknown-linux-musl
-# the reason we had to do this is because cargo tries to use
-# the same toolchain as the target's name. but we can tell it to use
-# the GNU one like so.
-```
-
-your executable will be `target/aarch64-unkown-linux-musl/release/bingus-blog`.

-which will make bingus-blog try to read that file or fail and exit.

-# Custom Content
-
-bingus-blog supports loading custom content such as templates and static files
-at runtime from custom locations.
-
-the configuration options `dirs.custom_templates` and `dirs.custom_static`
-allow you to set where these files are loaded from.
-
-customizing the error page, other than CSS, is not supported at this time.
-
-## Custom Templates
-
-custom templates are written in
-[Handlebars (the rust variant)](https://crates.io/crates/handlebars).
-
-the *custom templates directory* has a non-recursive structure:
-
-```md
-./
-  - index.html # ignored
-  - index.hbs # loaded as `index`
-  - post.hbs # loaded as `post`
-  - [NAME].hbs # loaded as `[NAME]`
-  - ...
-```
-
-templates will be loaded from first, the executable, then, the custom
-templates path, overriding the defaults.
-
-template changes are also processed after startup, any changed template will be
-compiled and will replace the existing template in the registry, or add a
-new one (though that does nothing).  
-if a template is deleted, the default template will be recompiled into
-it's place.  
-note that the watcher only works if the *custom templates directory* existed
-at startup. if you delete/create the directory, you must restart the program.
-
-## Custom Static Files
-
-GET requests to `/static` will first be checked against `dirs.custom_static`.
-if the file is not found in the *custom static directory*, bingus-blog will try
-to serve it from the directory embedded in the executable. this means you can
-add whatever you want in the *custom static directory* and it will be served
-under `/static`.
-
-## Custom Media
-
-the endpoint `/media` is served from `dirs.media`. no other logic or mechanism
-is present.

-## Non-static Routes
+## Routes

 - `GET /`: index page, lists posts
 - `GET /posts`: returns a list of all posts with metadata in JSON format
 - `GET /posts/<name>`: view a post
 - `GET /posts/<name>.md`: view the raw markdown of a post
 - `GET /post/*`: redirects to `/posts/*`
- `GET /feed.xml`: RSS feed

 ## Cache

 bingus-blog caches every post retrieved and keeps it permanently in cache.
-there is a toggleable cleanup task that periodically sweeps the cache to
-remove dead entries, but it can still get quite big.
+the only way a cache entry is removed is when it's requested and it does
+not exist in the filesystem. cache entries don't expire, but they get
+invalidated when the mtime of the markdown file changes.

-if cache persistence is on, the cache is (compressed &) written to disk on
-shutdown, and read (& decompressed) on startup. one may opt to set the cache
-location to point to a tmpfs to make it save and load quickly, but not persist
-across reboots at the cost of more RAM usage.
+if cache persistence is on, the cache is compressed & written on shutdown,
+and read & decompressed on startup. one may opt to set the cache location
+to point to a tmpfs so it saves and loads really fast, but it doesn't persist
+across boots, also at the cost of even more RAM usage.

-in my testing, the compression reduced a 3.21 MB cache to 0.18 MB almost
-instantly. there is basically no good reason to not have compression on,
-unless you have filesystem compression already of course.
