Pagine v2.4.3

Pagine is an high-performance website constructor that makes full use of multicore hardware.

Build jobs can be completed very fast.

Features

Parallel hierarchy processing and unit execution. Everything is executed in parallel from beginning to end.
Hierarchical metadata propagation which makes metadata management easy.
Manage templates and assets via Git. Every template can be distributed and used without modification.
In-template builtin functions
Interact with Pagine in templates.
Multi-stage workflow.

As server: update web content on file change.

Supported rich text formats:

Asciidoc
Markdown
MathJax support provided in Documentor

Install

Binaries

Find the executable that matches your OS and architecture in releases.

Build from source

$ go install github.com/webpagine/pagine/v2/cmd/pagine@v2.4.1

Tip

Install Pagine via Go mod is recommended for non-amd64 platforms. Choose Go toolchain for your platform here.

Usage

Usage of pagine:

-public string
- Location of public directory. (default /tmp/$(basename $PWD).public)
-root string
- Site root. (default $PWD)
-serve string
- Specify the port to listen and serve as HTTP.

Generate

$ cd ~/web/my_site
$ pagine
Generation complete.

Run as HTTP server

$ cd ~/web/my_site
$ pagine --serve :12450

It automatically executes generation when file changes are detected by inotify.

Note

Incremental generation is not implemented yet.
Set the --public under /tmp is recommended to reduce hard disk writes.

Since v2.1.0, the server provides a WebSocket interface at /ws to provide event monitoring for the client, such as page updates.

Caution

Exposing your Pagine server to the public network might be risky! You should deploy your final pages via static page services.

Structure

Template

Template is a set of page frames (Go template file) and assets (e.g. SVGs, stylesheets and scripts).

Manifest of one template looks like:

manifest:
  canonical: "com.symboltics.pagine.genesis" # Canonical name
  patterns:
    - "/*html"                               # Matched files will be added as template file.

templates:
  - name: "page"        # Export as name `page`
    export: "page.html" # Export `page.html`

  - name: "post"        # Export as name `post`
    export: "post.html" # Export `post.html`

To the Go templates files syntax, see text/template.

Example: page.html

<html lang="{{ .lang }}">
<head>
    <title>{{ .title }}</title>
    <link rel="stylesheet" href="{{ api.Attr.templateBase }}/css/base.css"/>
</head>
<body>
{{ template "header.html" . }}
<main>{{ render.ByFileExtName .content }}</main>
</body>
{{ template "footer.html" . }}
</html>

Env

"Environment" is the configuration of the details of the entire process.

ignore: # Pattern matching. Matched files will not be **copied** to the public/destination.
  - "/.git*"

use: # Load and set alias for the template.
  genesis: "/templates/genesis"
  documentor: "/templates/documentor"

Installing templates via Git submodule is recommended. Such as:

$ git submodule add https://github.com/webpagine/genesis templates/genesis

Level

Each "level" contains its metadata. And a set of units to be executed.

For directories, metadata sets are stored in metadata.toml in the form of map, and units are stored in unit.toml

Each template has its alias that defined in env as the namespace.

Levels can override fields propagated from parents.

Example: /metadata.yaml

genesis:
  title: "Pagine"

  head:
    icon: "/favicon.ico"

    nav:
      items:
        - name: "Documentation"
          link: "/docs/"

Unit

Example: /unit.yaml

unit:
  - template: "genesis"      # Which template to use.
    template_key: "page"     # Which the key refers to.
    output: "/index.html"    # Where to save the result.
    define:
      title: "Pagine"        # Unit-specified metadata.
      content: "README.md"

  - template: "genesis"
    template_key: "page"
    output: "/404.html"
    define:
      title: "Page not found"
      content: "404.md"

Multi-stage Workflow

All paths are based on the directory where the workflow.yaml is located.

Workflow

Workflows are executed in parallel.

Example: workflow.yaml

stage:
  - job:
      - type: "tsc/v1"
        title: "Build TypeScript"
        path: "/script/"

Stage

Stages are executed in order. Each stage contains a set of jobs.

Job

Jobs are executed in parallel.

Job Builder

The Job Builder is one special-purpose template like embedded program. It accepts API and configuration information from the engine and outputs processed job information to the engine.

Environment variable PAGINE_JOB_BUILDER_ROOT has been used to specify the root location of external job builders.

Builder lookup order:

PAGINE_JOB_BUILDER_ROOT from env.
Builtin: /workflow/builtin in this repository.

API	Type	Description
job	`map[string]any`	Job field.

Field of `job`	Type	Description
`title`	`string`	Title show in log output
`executable`	`string`	Executable in `$PATH`
`args`	`[]string`	Arguments

Builtin Job Builders

TypeScript compiler (tsc)

type: "tsc/v1"
title: "Build TypeScript"
path: "/script/"

Make sure tsc had been installed on target machine.

FAQ

Why another generator? Isn't Hugo enough?

Pagine is not Hugo, and is not aim to replace Hugo.

Pagine does not embed page configurations in Markdown file, they are separated and should be separated.

And Pagine does not focus on Markdown only, I hope to support various kinds of source.

Can I use Pagine for building complex web application?

Yes. It can help you get rid of repetitive work about static contents.

And templates can also increase productivity as long as Pagine well integrated with external tools via workflow.

Co-operate with external tools such as TypeScript compiler or npx?

It can be done via workflow.

What is the origin of the logo and name?

It is neither a browser engine, a layout engine nor a rendering engine.

Page Gen × Engine ⇒ Pagine. It has similar pronunciation to "pagen".

The logo is an opened book with a bookmark.

Rewrite it in other PL?

I expected somebody would ask.

It will not be taken unless it does bring obvious advantages.

Thus: NO. It is not planned currently.
