-# _kewt_

 ### Pronounced "cute"
 
+***

 # [Go to the website](https://kewt.krzak.org)
 
+***
+
 _kewt_ is a minimalist ssg inspired by _[werc](http://werc.cat-v.org/)_ and _[kew](https://github.com/uint23/kew)_
 
-It's meant to be a static site generator, like _[kew](https://github.com/uint23/kew)_ but use only default (POSIX) tooling, like _[werc](http://werc.cat-v.org/)_ (and definitely unlike _[kew](https://github.com/uint23/kew)_)
 
-## Features
+## [Installation](https://kewt.krzak.org/docs/installation)
 
-- No dependencies
+## Contributing
-- Supports many embed types
-- Automatic css variable replacement for older browsers
-- Automatic inlining and embedding of many filetypes with `\![link]` or `\![alt](link)`
-- Inline html support
-- MFM `$font` and `\<plain>` tags
-- Admonition support (that's what the blocks like the warning block below are called)
 
-If you want to **force** a file to be inlined, use `\!![]` instead of `\![]`
+Either open an issue or pull request on the **home** repository ([N0VA/kewt](https://git.krzak.org/N0VA/kewt)) or message me on my email address ([n0va@krzak.org](mailto:n0va@krzak.org?subject=%5Bkewt%5D%20something)) with the subjectline being `[kewt] something`.
 
-## Usage
+## License
 
-```sh
+ISC
-./kewt.sh --help
-./kewt.sh --new [title]
-./kewt.sh --from <src> --to <out>
-./kewt.sh [src] [out]
-```
-
-`--new [title]` creates a new site directory with a copied `site.conf` and a default `index.md`.
-
-## site.conf
-
-```conf
-title = "kewt"
-style = "kewt"
-dir_indexes = true
-single_file_index = true
-flatten = false
-footer = "made with <a href="https://kewt.krzak.org">kewt</a>"
-logo = ""
-display_logo = false
-display_title = true
-logo_as_favicon = true
-favicon = ""
-```
-
-- `title` site title
-- `style` style file name from `./styles` (without `.css`)
-- `dir_indexes` generate directory index pages when missing `index.md`
-- `single_file_index` if a directory has one markdown file and no `index.md`, use that file as `index.html`
-- `flatten` flatten sidebar directory levels
-- `footer` footer html/text shown at the bottom of pages
-- `logo` logo image path (used in header if enabled)
-- `display_logo` show logo in header
-- `display_title` show title text in header
-- `logo_as_favicon` use `logo` as favicon
-- `favicon` explicit favicon path (used when `logo_as_favicon` is false or no logo is set)
-
-## Embeds
-
-- `\![link]`:
-  - local image/audio/video files are embedded as media tags
-  - local text/code files are inlined directly
-  - global image/audio/video links are embedded as media tags
-  - other global links are embedded as `<iframe>`
-- `\![alt](link)` works the same, with `alt` used for images
-- `\!![]` and `\!![alt](link)` force inline local file contents
-
-## Credits
-
-- Markdown to html conversion based on [markdown.bash](https://github.com/chadbraunduin/markdown.bash) by [chadbraunduin](https://github.com/chadbraunduin)
-- Default css style and html template based on _[kew](https://github.com/uint23/kew)_ by [uint23](https://github.com/uint23)

+# Markdown Extensions
+
+## Directory Index Customisation
+
+By default, directories without an `index.md` get an auto-generated index page listing their contents.
+
+If you create your own `index.md` in a directory, you can still include the auto-generated file list by using the `{{LIST}}` placeholder:
+
+```md
+# Blog
+
+This is my blog. The posts are below. The top-most one is the most recent.
+
+{{LIST}}
+```
+The `{{LIST}}` placeholder is replaced with the autogenerated file list.
+
+## Table of Contents
+
+`{{TOC}}` auto-generates a nested heading list with clickable anchors.
+
+## Footnotes
+
+Full support for `[^id]` footnotes and `[^id]: text` definitions. They render as a numbered `<section>` at the bottom of the page.
+
+## Definition Lists
+
+Definition lists use the standard syntax:
+
+```md
+Term
+: Definition
+```
+This renders as `<dl><dt>Term</dt><dd>Definition</dd></dl>`. Multiple definitions per term are supported.
+
+## Emoji Shortcodes
+
+Standard GitHub/MkDocs emoji shortcodes like `:smile:`, `:fire:`, `:rocket:` are automatically replaced with their Unicode emoji equivalents. Shortcodes inside codeblocks are left as-is.
+
+## Pipe Tables
+
+Tables use the GitHub-style syntax:
+
+```md
+| Header 1 | Header 2 |
+|---|---|
+| cell 1 | cell 2 |
+| cell 3 | cell 4 |
+```
+Column alignment is set with colons in the separator:
+
+```md
+| Left | Center | Right |
+|:---|:---:|---:|
+| a | b | c |
+```
+Tables can drop the header row and with a separator:
+
+```md
+|---|---|
+| a | b |
+```
+## Blockquotes
+
+Standard Markdown blockquote syntax using `>`:
+
+```md
+> This is a blockquote.
+> It can span multiple lines.
+```
+### Admonitions
+
+Blockquotes that start with a type tag become styled admonition blocks. Five built-in types are supported: `NOTE`, `TIP`, `IMPORTANT`, `WARNING`, `CAUTION`.
+
+```md
+> [!NOTE]
+> This is a note admonition.
+```
+Custom admonition types can be added via the `custom_admonitions` config option in `site.conf`.
+
+## Task Lists
+
+GFM-style task lists are supported inside **both** ordered and unordered lists:
+
+```md
+- [ ] Unchecked item
+- [x] Checked item
+- Normal item
+
+1. [ ] Unchecked item
+2. [x] Checked item
+3. Normal item
+```
+## Reference Links
+
+Markdown reference-style links and images are supported:
+
+```md
+[link text][ref]
+
+[ref]: https://example.com "Optional title"
+
+![alt text][img-ref]
+
+[img-ref]: /image.png "Optional title"
+```
+## Plain Text Blocks
+
+Content inside `<plain>...</plain>` tags is rendered without any Markdown processing
+
+## MFM Font Syntax
+
+Misskey-style font syntax is supported for inline font family changes:
+
+- `$[font.serif text]` - serif font
+- `$[font.mono text]` - monospace font
+- `$[font.sans text]` - sans-serif font

+## Creating a site
+
+```sh
+kewt --new mysite
+cd mysite
+```
+This creates a directory with a `site.conf`, `template.html`, and `index.md`.
+
+## Writing content
+
+Edit `index.md` (or any `.md` file) and just write markdown as usual. Files in subdirectories are added to the navigation automatically.
+
+## Building
+
+```sh
+kewt src out # Replace with the directories you want
+```
+Reads from `src` and writes static HTML to `out`.
+
+## Previewing
+
+```sh
+kewt --serve
+```

+- `{{TITLE}}` - the generated title
+- `{{NAV}}` - the generated navigation
+- `{{FOOTER}}` - the configured footer
+- `{{VERSION}}` - the cache-busting string from `versioning = true` (e.g. `?v=12345678`). Safe to use even if versioning is **disabled** (it will be empty).
+- `{{CSS}}` - the configured CSS file path

+- `{{HEAD_EXTRA}}` - meta-tags
+- `{{HEADER_BRAND}}` - header rendering the name and/or logo
+- `{{HEADER_SEARCH}}` - header search form when `search_in_header = true`
+
+## Search
+
+When `generate_search` is enabled, kewt embeds a search bar into pages based on the `search_in_header` and `search_in_footer` config options. The search uses a `search.json` index generated at build time and a client-side JS script. No external dependencies are required.
+
+If you use a custom template and want header search enabled, make sure your `template.html` includes `{{HEADER_SEARCH}}` somewhere inside `<header>`.

+*kewt* has a few colour palettes built-in. Set the `style` option in `site.conf` to a theme name to apply it.
+
+## Built-in Themes
+
+| Theme | `style` value | Dark/Light |
+|---|---|---|
+| Kewt (default) | `kewt` | Light |
+| Kewt Light | `kewt-light` | Light |
+| Nord | `nord` | Dark |
+| Nord Light | `nord-light` | Light |
+| Monokai | `monokai` | Dark |
+| Monokai Light | `monokai-light` | Light |
+| Grayscale | `grayscale` | Dark |
+| Grayscale Light | `grayscale-light` | Light |
+| One Dark | `onedark` | Dark |
+| One Light | `onelight` | Light |
+| Rose Pine | `rosepine` | Dark |
+| Rose Pine Light | `rosepine-light` | Light |
+| Solarized | `solarized` | Light |
+| Solarized Dark | `solarized-dark` | Dark |
+
+```conf
+style = "kewt-light"
+```
+## How It Works
+
+Each theme is a `.root.css` file containing a `:root` block with CSS custom properties. At build time, *kewt* merges the theme's variables with the base `kewt.css` stylesheet. The base `:root` block is stripped out and replaced with the theme's variables.
+
+## Style Resolution
+
+*kewt* resolves styles in this priority order (highest wins):
+
+1. `site/styles.css` - a full custom stylesheet in your site directory. Overrides everything.
+2. `site/styles.root.css` - custom `:root` variables merged with the built-in `kewt.css` base.
+3. built-in `<style>.css` - a full stylesheet matching the `style` config value.
+4. built-in `<style>.root.css` - `:root` variables merged with `kewt.css`.
+
+If none of these exist, the unmodified `kewt.css` is used
+
+## Custom Themes
+
+To create a custom colour theme, place a `styles.root.css` file in your site directory. The file should contain only a `:root` block with the CSS variables you want to override:
+
+```css
+:root {
+    --bg: #1a1b26;
+    --fg: #c0caf5;
+    --fg-link: #7aa2f7;
+    --fg-heading: #c0caf5;
+    --code-bg: #24283b;
+}
+```
+Any variables not overridden will fall back to the defaults in `kewt.css`. The `:root` block in the base stylesheet is automatically removed to prevent conflicts.
+
+## Per-Directory Styles
+
+Subdirectories can have their own `styles.css` or `styles.root.css` that apply only to pages in that directory. Per-directory styles follow the same priority.

+- `--generate-template [path]` writes the default `template.html` to the given path (defaults to `template.html` in the current directory).
+- `--update [dir]` adds any missing keys to `site.conf` and checks `template.html` against the latest default.
+- `--watch` (`-w`) watches for file changes in the source directory and rebuilds automatically.
+- `--clean` cleans the output directory before building (default behavior).
+- `--no-clean` does not clean the output directory before building. Useful with `--watch` to avoid clearing output on every rebuild.
+- `--serve` (`-s`) starts a local HTTP server (python3 or busybox) in the output directory after building. Use with the port number to specify the port. The default port is `8000`. Composable with `--watch`.
