It should be fast enough to completely regenerate even very large sites in near real-time if needed. ## 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. It's 10x faster than the old version in Python. ## Status It powers [trenchant.org](https://trenchant.org) but is under active development and pieces may change. See TODO for future / in progress work. # Installation The only dependency for building is `go`. [Install Go](https://golang.org/doc/install) for your platform. Download and build `snkt` with something like $ go get adammathes.com/snkt This will download dependencies, build `snkt` and place it in your $GOPATH/bin (by default, ~/go/bin/). `snkt` is a self-contained binary, you can move it anywhere. # Quick Start ## Creating a Site Use the "-init" option to create the skeleton for a new site - $ snkt -i myblog This will create: * `txt` directory for posts * `html` directory for HTML output * `tmpl` directory for templates * `base` HTML structure wrapper * `archive` lists all posts * `post` single post page * `home` home page with recent posts * `rss` RSS 2.0 * `config.yml` configuration file ## First Post A one line plaint text file is a valid post. user@host:~/myblog$ 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` ## Viewing the Results `snkt` includes a simple web server to view the results with $ snkt -s Visiting http://localhost:8000 in a web browser should now show the site and the first post. You can now copy this HTML anywhere and you're set. # Command Line Options ``` Usage of snkt: -b, --build generates site from input files and templates -c, --config configuration configuration file (default "config.yml") -h, --help print usage information -i, --init directory initialize new site at directory -s, --serve serve site via integrated HTTP server -v, --verbose log operations during build to STDOUT -w, --watch watch configured input text dir, rebuild on changes ``` Examples $ snkt -c site.yaml -b $ snkt --config=myconfig.yml -v -w # Configuration Per site configuration is via a [YAML](http://yaml.org) file. 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 | | | `site_url` | absolute URL for the site | | | `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/). Entities in the templates -- **Site** ``` Title string URL string Posts array of posts ``` See site/site.go for more. **Post** ``` // Metadata Meta map[string]string SourceFile string Title string Permalink string 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 ``` ## home Displays recent posts and rendered to `index.html` in the `output_dir`. - {{.Site}} *Site* - {{.Posts}} *Posts* all posts on site in reverse chronological order ## post Each individual post uses this template - {{.Site}} *Site* - {{.Post}} *Post* the individual post ## 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 Configuration Options ## Permalink and filename formatter Permalinks (URLs for individual posts) can be customized. | 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/" ``` # Work in Progress Features These features are working but less documented and potentially still in progress and subject to change. ## Paged Archives If a template named `paged` is present then paged archives (15 posts per page) are created at `output_dir/page/%d.html` Template variables are the same as the `archive` template, but with `.NextPage` and `.PrevPage` as integers of the next and previous page. See archive/paged.go for details. ## Tags There is preliminary support for tag style metadata per post. Add a "tags" field to your post preamble. Tags should be comma separated. ``` tags: TagOne, tag two, a third tag, fourth ``` Tags will be normalized to lowercase, with spaces replaced with underscores. So the above would have tagged a post with -- `tagone tag_two a_third_tag fourth` Tags are accessible in each post via the `Tags` field. To create pages by tag, create a template named `tags`. This creates a file at OUTPUT_DIR/tag/tag_name/index.html for each tag. It will have access to the same variables as an `archive` template with the additional `.Tag` for the tag name. ## Binary Files as Posts Preliminary support to treat binary files as standalone posts. Drop image files with "jpg" or other image extensions into the "txt" dir. * post's ContentType will be set to "image" * text fields will be empty strings * metadata will be populated as it can via exif (maybe) Video and audio files have preliminary support too -- see `post/post.go` # Example configurations, sites, themes *not done* # Rebuild and deployment recipes *also not done* # TODO * sample sites/templates * proper man pages for docs # Feedback Pull requests and issues are welcomed at https://github.com/adammathes/snkt
