| 18 | ## Installation
|
|---|
| 19 |
|
|---|
| 20 | Download the binaries from Github or build it manually:
|
|---|
| 21 |
|
|---|
| 22 | $ go get git.mills.io/prologic/zs
|
|---|
| 23 |
|
|---|
| 24 | ## Ideology
|
|---|
| 25 |
|
|---|
| 26 | Keep your texts in markdown, or HTML format right in the main directory
|
|---|
| 27 | of your blog/site.
|
|---|
| 28 |
|
|---|
| 29 | Keep all service files (extensions, layout pages, deployment scripts etc)
|
|---|
| 30 | in the `.zs` subdirectory.
|
|---|
| 31 |
|
|---|
| 32 | Define variables in the header of the content files using [YAML]:
|
|---|
| 33 |
|
|---|
| 34 | title: My web site
|
|---|
| 35 | keywords: best website, hello, world
|
|---|
| 36 | ---
|
|---|
| 37 |
|
|---|
| 38 | Markdown text goes after a header *separator*
|
|---|
| 39 |
|
|---|
| 40 | Use placeholders for variables and plugins in your markdown or html
|
|---|
| 41 | files, e.g. `{{ title }}` or `{{ command arg1 arg2 }}.
|
|---|
| 42 |
|
|---|
| 43 | Write extensions in any language you like and put them into the `.zs`
|
|---|
| 44 | subdiretory.
|
|---|
| 45 |
|
|---|
| 46 | Everything the extensions prints to stdout becomes the value of the
|
|---|
| 47 | placeholder.
|
|---|
| 48 |
|
|---|
| 49 | Every variable from the content header will be passed via environment variables like `title` becomes `$ZS_TITLE` and so on. There are some special variables:
|
|---|
| 50 |
|
|---|
| 51 | * `$ZS` - a path to the `zs` executable
|
|---|
| 52 | * `$ZS_OUTDIR` - a path to the directory with generated files
|
|---|
| 53 | * `$ZS_FILE` - a path to the currently processed markdown file
|
|---|
| 54 | * `$ZS_URL` - a URL for the currently generated page
|
|---|
| 55 |
|
|---|
| 56 | ## Example of RSS generation
|
|---|
| 57 |
|
|---|
| 58 | Extensions can be written in any language you know (Bash, Python, Lua, JavaScript, Go, even Assembler). Here's an example of how to scan all markdown blog posts and create RSS items:
|
|---|
| 59 |
|
|---|
| 60 | ``` bash
|
|---|
| 61 | for f in ./blog/*.md ; do
|
|---|
| 62 | d=$($ZS var $f date)
|
|---|
| 63 | if [ ! -z $d ] ; then
|
|---|
| 64 | timestamp=`date --date "$d" +%s`
|
|---|
| 65 | url=`$ZS var $f url`
|
|---|
| 66 | title=`$ZS var $f title | tr A-Z a-z`
|
|---|
| 67 | descr=`$ZS var $f description`
|
|---|
| 68 | echo $timestamp \
|
|---|
| 69 | "<item>" \
|
|---|
| 70 | "<title>$title</title>" \
|
|---|
| 71 | "<link>http://zserge.com/$url</link>" \
|
|---|
| 72 | "<description>$descr</description>" \
|
|---|
| 73 | "<pubDate>$(date --date @$timestamp -R)</pubDate>" \
|
|---|
| 74 | "<guid>http://zserge.com/$url</guid>" \
|
|---|
| 75 | "</item>"
|
|---|
| 76 | fi
|
|---|
| 77 | done | sort -r -n | cut -d' ' -f2-
|
|---|
| 78 | ```
|
|---|
| 79 |
|
|---|
| 80 | ## Hooks
|
|---|
| 81 |
|
|---|
| 82 | There are two special plugin names that are executed every time the build
|
|---|
| 83 | happens - `prehook` and `posthook`. You can define some global actions here like
|
|---|
| 84 | content generation, or additional commands, like LESS to CSS conversion:
|
|---|
| 85 |
|
|---|
| 86 | # .zs/post
|
|---|
| 87 |
|
|---|
| 88 | #!/bin/sh
|
|---|
| 89 | lessc < $ZS_OUTDIR/styles.less > $ZS_OUTDIR/styles.css
|
|---|
| 90 | rm -f $ZS_OUTDIR/styles.css
|
|---|
| 91 |
|
|---|
| 92 | ## Command line usage
|
|---|
| 93 |
|
|---|
| 94 | `zs build` re-builds your site.
|
|---|
| 95 |
|
|---|
| 96 | `zs build <file>` re-builds one file and prints resulting content to stdout.
|
|---|
| 97 |
|
|---|
| 98 | `zs watch` rebuilds your site every time you modify any file.
|
|---|
| 99 |
|
|---|
| 100 | `zs var <filename> [var1 var2...]` prints a list of variables defined in the
|
|---|
| 101 | header of a given markdown file, or the values of certain variables (even if
|
|---|
| 102 | it's an empty string).
