GPub: A Go Publishing Utility

Overview

Note: GPub is under active development and users may find unexpected API-breaking changes until a 1.0.0 release occurs

GPub is a book-generating platform written in JavaScript, with the goal of quickly making high-quality Go/Baduk/Wei-Qi books without the need for auxilary software.

Currently, I am working to support generating books in 3 formats: PDF (for print), GoBooks (SmartGo), and EPub (Ebooks).

Pre-Setup Steps

1. Install LaTeX
2. Install the Gnos Font. For font-installation instructions, see Kashomon/go-type1. The recommended font is gnos.
3. Install NodeJS

The CLI

GPub has a rudamentary CLI for generating books, images, and preforming other useful SGF-related tasks.

Installation

Install with NPM:

npm install -g gpub-go

Or manually:

git clone [email protected]:Kashomon/gpub.git

# Install the necessary node modules
cd gpub
npm install

# Add to your bashrc/bash_profile
alias gpub='/Users/kashomon/inprogress/gpub/cmd/gpub.js'

With this tool, you now have the ability to create Go images!

Spec Generation

The GPub spec is a YAML or JSON file that specifies the SGFs you want processed into a book or images. To get one started, use

gpub init-spec

This will crawl the current directory looking for SGFs and then sort them.

Currently, GPub supports two types of 'books': Commentary books and problem books. The default is a COMMENTARY_LATEX. Here are the options:

• PROBLEM_LATEX (default): Make a problem book PDF, using LaTeX.
• PROBLEM_EBOOK: Make a problem book, as an EBook.
• COMMENTARY_LATEX: Make a game commentary book PDF, using LaTeX.

[Optional] Spec Processing

The initial GPub spec created from the above is very rudamentary. GPub must figure out which images should be generated. In order to do that, the spec needs to be 'processed'. This can be done separately or it can be combined with later steps.

gpub process --input my-spec.yaml

[Optional] Image Generation

Next, GPub takes the processed Spec and generates images from the combination of the SGFs and the positional information from the spec.

By default, gpub creates a generated output-directory called diagrams, and also auto-processes the spec (previous step).

gpub render-diagrams --input my-spec.yaml

By default, gpub gets the diagram type from the spec, but this can be overridden:

gpub render-diagrams --input my-spec.yaml --diagram-type SVG

Also, if it's helpful, you can write the comments that go with the diagrams to .txt files:

gpub render-diagrams --input go-book.yaml --write-comments

Important Note: By default, the comments are interpreted as Markdown and processed as such into LaTeX. So, **FooBar** becomes \textbf{FooBar}.

Book Generation

TODO(Kashomon): Add this functionality.

Book Generation doesn't currently work. As such, this is an aspirational goal

Extras

The GPub CLI also has some helpers I've found useful:

Parse go files. Autodetect and parse go files. Currently just supports Tygem (gib) and SGF files.

# Specify individual files
gpub parse -f foo.gib,bar.gib -o $CWD

# Specify  an input directory
gpub parse -i path/to/tygem/files

Development

If you want to do development on GPub, you will additionally need:

1. The Java runtime environment
2. Install Gulp -- JavaScript task runner
3. Install dependencies via npm install
4. Run the full test+build gulp build-test

About Gpub

GPub grew out of another library I created called Glift.

GPub that relies on the same go-processing logic as Glift. This core logic lives in a library (called glift-core) is is responsible for providing an understanding of go files and generated a flattened representation of a go position, while GPub is responsible for generating an intermediate representation and for the ultimate rendering diagrams for print

Diagram Type

Diagram Type indicates how diagrams should be rendered. Note that most diagrams have an intended target output format. It is left as future work to indicate to the user how the diagram types are restricted.

Various diagram types:

• GNOS: Uses the Gnos LaTeX font.
• GOOE: Uses the GOOE LaTeX font
• IGO: Uses the IGO LaTeX font (*not currently supported).
• SVG: Generate raw SVGs (*not currently supported).
• PDF: Generate raw PDFs (*not currently supported).

Styling via Markdown

By default, GPub uses Markdown to add styling to diagram comments via Marked.js. In the near future, all the major output formats will support custom renderers. See the Markdown Page for more details about the supported syntax.

GPub also uses Markdown to gather diagram-level Metadata. The following headers will be used to generate chapter-data.

# Foo Bar => Book Foo Bar
## Foo Bar => Part Foo Bar
### Foo Bar => Chapter Foo Bar

Development

To work on / contribute to Gpub, you will need to install:

• NodeJS
• Gulp
• Java (for the closure compiler, ebook-validator)
• LaTeX/XeLaTeX (for making LaTeX/XeLaTeX books)
• Calibre and/or Kindle App (for making/viewing ebooks)

Then, to install all the deps, you'll need:

npm install

And then to run the tests:

gulp build-test
