|
||||
## Design
|
||||
|
||||
Can be used for blogs or general static pages
|
||||
|
||||
Commands:
|
||||
|
||||
- new: start a new project -> creates the structure + default config.toml
|
||||
- build: reads all the .md files and build the site with template
|
||||
- serve: starts a server and watches/reload the site on change
|
||||
|
||||
|
||||
All pages go into the `content` folder. Subfolder represents a list of content, ie
|
||||
|
||||
```bash
|
||||
├── content
|
||||
│ ├── posts
|
||||
│ │ └── intro.md
|
||||
│ └── some.md
|
||||
```
|
||||
|
||||
`some.md` will be accessible at `mywebsite.com/some` and there will be other pages:
|
||||
|
||||
- `mywebsite.com/posts` that will list all the pages contained in the `posts` folder
|
||||
- `mywebsite.com/posts/intro`
|
||||
|
||||
|
||||
### Building the site
|
||||
Get all .md files in content, remove the `content/` prefix to their path
|
||||
Split the file between front matter and content
|
||||
Parse the front matter
|
||||
markdown -> HTML for the content
|
||||
TO THINK OF: create list pages for folders, can be done while globbing I guess?
