# snkt `snkt` is a static web site generator for with a focus on simplicity and efficiency. snkt only does a few things, but strives to do them well, in a coherent manner. snkt generates my [personal web site of ~2000 articles in under a second](https://trenchant.org/daily/2017/1/31/). Additional work may be done to increase efficiency, but it should be fast enough to regularly regenerate your site without concern in near real-time if needed. ## Status Currently in development. It powers [trenchant.org](https://trenchant.org) but is "alpha" quality and parts may change. ## TODO * finish these docs * half-baked / may change * permalink formatter * filters * date handling in templates * additional functions in templates * themes + example sites * complex archive types * multiple archives/lists/post outputs ## What Takes a bunch of plain text files, processes them via templates, and generates HTML. Pretty much like you'd expect of a static site generator. ## Why Every 5-10 years I throw out the software for my site and rewrite it. This time it's in Go. Maybe you'll find it useful. I found it fun to get myself thinking in Go. Also, it's 10x faster than the old version in Python. ## Getting snkt [Install Go](https://golang.org/doc/install) Set up $GOPATH $ mkdir $HOME/go $ export GOPATH=$HOME/go Add $GOPATH/bin to your PATH $ export PATH=$PATH:$GOPATH/bin Get and install dependencies $ go get gopkg.in/yaml.v2 $ go get github.com/russross/blackfriday Download `snkt` $ go get adammathes.com/snkt Build `snkt` $ go build adammathes.com/snkt This should download and build `snkt` and place it in $GOPATH/bin ## Setting up a site Use the "-init" option to create the skeleton for a new site - $ snkt -init blogadu This will create: * `txt` directory for plain text input * `html` directory for HTML output * `tmpl` directory for templates * `base` basic HTML structure for all pages * `post` single post page template * `home` - home page with recent posts template * `archive` - list all posts template * `rss` - template for an RSS 2.0 archive * `config.yml` -- configuration file ## First Post A one line plaint text file is a valid post. user@host:~/blogadu$ echo "hello world" >> txt/hi Build the site $ snkt -b Output should now be in the `html` directory and look like * `html` * `hi/index.html` hello world post * `index.html` * `archive.html` * `rss.xml` Run a preview server to see the results with $ snkt -p Loading http://localhost:8000 in a web browser should now show the (near empty) site. ## Command Line Usage ``` Usage of snkt: -b build site -c configuration configuration file (default "config.yml") -h help -init directory initialize new site at directory -p preview site with local HTTP server -v print version number -verbose log actions during build ``` ## Configuration File The configuration is in [YAML](http://yaml.org) For most purposes, it should just be a listing of attribute : value Configuration options -- | name | value | default | |------------------|--------------------------------------------------|----------------| | `input_dir` | absolute path of directory for text input files | | | `output_dir` | absolute path of directory for html output files | | | `tmpl_dir` | absolute path of directory for template files | | | `site_title` | string for the site's title (used in templates) | | | `site_url` | absolute URL for the site (used in templates) | | | `filters` | list of search/replace regex's to run on posts | | | `permalink_fmt` | format string for permalinks | /%F/ | | `post_file_fmt` | format string for post filenames | /%F/index.html | | `show_future` | include posts with dates in the future | false | | `preview_server` | host:port to spawn the preview server | localhost:8000 | | `preview_dir` | root directory of preview server | `output_dir` | ## Posts Post inputs are stored as plain text files. (I have only tested UTF-8 and ASCII.) Posts have an optional metadata preamble, and a markdown formatted body. The preamble is just a series of name value pairings separated by a colon (:) character. Minimal complete and valid post -- this is a totally valid post Post with a preamble -- title: also a valid post date: 2017-02-08 valid: totes This post will have an explicitly set title (ooh! fancy!) instead of inferred from the filename. It will also have an explicitly set date instead of inferring it from the file creation/modification time. `totes` will be stored in the post's `meta` map under `valid.` You don't have to worry about that right now. Honest. ## Templates Templates use the standard library [Go text/template](https://golang.org/pkg/text/template/). ### Types #### Site (see site/site.go) ```go Title string URL string Posts post.Posts ``` #### Post (see post/post.go) ```go // Metadata Meta map[string]string SourceFile string Title string `json:"title"` Permalink string `json:"permalink"` Time time.Time Year int Month time.Month Day int InFuture bool // Content text -- raw, unprocessed, unfiltered markdown Text string // Content text -- processed into HTML via markdown and other filters Content string // Content with sources and references resolved to absolute URLs AbsoluteContent string // Post following chronologically (later) Next *Post // Post preceding chronologically (earlier) Prev *Post // Precomputed dates as strings Date string RssDate string FileInfo os.FileInfo Site sitemeta ``` ### home Displays recent posts. Rendered to `index.html`. - {{.Site}} *Site* - {{.Posts}} *Posts* all posts on site, reverse chronological order ### post Template that gets rendered to create individual post pages - {{.Site}} *Site* - {{.Post}} *Post* the individual post the page is for ### archive Lists all posts, showing only titles and links. Rendered to `archive.html` - {{.Site}} *Site* - {{.Posts}} *Posts* all posts, reverse chronological order ### rss Displays recent posts as RSS 2.0 XML. Rendered to `rss.xml` - {{.Site}} *Site* - {{.Posts}} *Posts* all posts, reverse chronological order ## Advanced Features ### paged template If present renders paged archives (15 posts per page) to `page/%d.html` See archive/paged.go for details. Used to create an "infinite scroll" style archive. Details/options/implementation may change. ### Permalink and filename formatter Permalink (URLs for individual posts) can be customized. This part is *meh* and subject to change. | String | Value | Example | |--------|----------|---------| | %Y | Year | 2017 | | %M | Month | 04 | | %D | Day | 14 | | %F | Filename | foo | | %T | Title | bar | `Filename` is a cleaned version of the post's original filename with the extension removed. Filenames and titles will be "cleaned" of characters unsuitable for links, with whitespace replaced by `-`. ### Filters Arbitrary regular expressions can be executed on each post to create domain-specific and site-specific modifications. Here are the real world examples of regular expressions that filter each post on my personal site - ```yaml filters: - s: r:
- s: r:

· · ·

- s: r:

- s: "amazon:(.+)" r: "http://www.amazon.com/exec/obidos/ASIN/$1/decommodify-20/" ``` ### Example configurations/sites/themes *not done* ### Auto-rebuild/deployment *also not done*
