Crowbook ======== [![Build Status](https://travis-ci.org/lise-henry/crowbook.svg?branch=master)](https://travis-ci.org/lise-henry/crowbook) Render a book written in markdown to HTML, Epub or PDF. Crowbook's purpose is to allow you to automatically generate multiple outputs formats from a book written in Markdown. Its main focus is novels, and the default settings should (hopefully) generate readable books with correct typography. Example ------- To see what Crowbook's output looks like, you can read (a not-necessarily up-to-date version of) the Crowbook guide (containing this README.md file and additional documentation) rendered in [HTML](http://lise-henry.github.io/crowbook/book.html), [PDF](http://lise-henry.github.io/crowbook/book.pdf) or [EPUB](http://lise-henry.github.io/crowbook/book.epub). Installing ---------- ### Packages ### If you are on Debian GNU/Linux or Ubuntu (on a PC architecture), you can download `.deb` packages on [the releases page](https://github.com/lise-henry/crowbook/releases). ### Binaries ### See [the releases page](https://github.com/lise-henry/crowbook/releases) to download a precompiled binary for your architecture (currently: Linux, Windows and MacOSX). Just extract the archive and run `crowbook` (or `crowbook.exe` on Windows). You might also want to copy the binary somewhere in your `PATH` for later usage. ### Building ### You'll need to have the [Rust](https://www.rust-lang.org/) compiler on your machine first; you can [download and install it here](https://www.rust-lang.org/downloads.html). Once it is down: ```bash $ cargo install crowbook ``` will automatically download the latest `crowbook` release on [crates.io](https://crates.io/crates/crowbook) and install it. Usage ----- The simplest command is: ```bash $ crowbook ``` where `BOOK` is a configuration file. Crowbook will parse this file and generate a book in HTML, Epub, LaTeX, and/or PDF, according to the settings in the configuration file. To create a new book, assuming you have a list of Markdown files, you can generate a template configuration file with the `--create` argument: ```bash $ crowbook --create my.book chapter_*.md ``` This will generate a default `my.book` file, which you'll need to complete. This configuration file contains some metadata, options, and lists the Markdown files. For more information see [the configuration file](book_example/config.md). It is also possible to give additional parameters to `crowbook`; we have already seen `--create`, but if you want the full list, see [the arguments](book_example/arguments.md). Current features ---------------- ### Output formats ### Crowbook should correctly support HTML and EPUB (either version 2 or 3) as output formats: rendered files should pass respectively the [W3C validator](https://validator.w3.org/) and the [IDPF EPUB validator](http://validator.idpf.org/) for a wide range of (correctly Markdown formatted) input files. See the example book rendered in [HTML](http://lise-henry.github.io/crowbook/book.html) and [EPUB](http://lise-henry.github.io/crowbook/book.epub) on github.io. LaTeX/PDF output is a bit more tricky: it should work reasonably well for novels (the primary target of Crowbook), but `pdflatex` might occasionally choke on some "weird" unicode character. See the example book rendered in [PDF](http://lise-henry.github.io/crowbook/book.pdf) on github.io. ODT output is currently experimental at best. It might work with very basic formatting but still needs a *lot* of work. You can still see the example book rendered in [ODT](http://lise-henry.github.io/crowbook/book.odt) on github.io to have an idea of the current status for this output format. ### Input format ### Crowbook uses [pulldown-cmark](https://crates.io/crates/pulldown-cmark) and thus should support most of CommonMark Markdown. Inline HTML, however, is not implemented, and probably won't be, as the goal is to have books that can also be generated in PDF (and maybe eventually ODT). Maybe the most specific "feature" of Crowbook is that (by default, it can be deactivated) it tries to "clean" the input files. By default this doesn't do much (except removing superfluous spaces), but if the book's language is set to french it tries to respect french typography, replacing spaces with non-breaking ones when it is appropriate (e.g. in french you are supposed to put a non-breaking space before '?', '!', ';' or ':'). This feature is relatively limited at the moment, but I might try to add more options and support for more languages. ### Links handling ### Crowbook tries to correctly translate local links in the input Markdown files: e.g. if you have a link to a markdown file that is part of your book, it will be transformed into a link inside the document. ### Inline YAML blocks ### Crowbook supports inline YAML blocks: ```yaml --- author: Me title: My title --- ``` This is mostly useful when Crowbook is runned with the `--single` argument (receiving a single Markdown file instead of a book configuration file). E.g., the following Markdown file: ```yaml --- author: John Doe title: A book output.html: book.html --- This is a very tiny book! ``` can be processed with `crowbook --single foo.md` or `crowbook -s foo.md` to produce the `book.html` file. This is useful for short texts that typically only contain one "chapter". ### Bugs ### See the [github's issue tracker](https://github.com/lise-henry/crowbook/issues). Contributors ------------ * [Stéphane Mourey](http://stephanemourey.fr/) `` Acknowledgements ---------------- Besides the [Rust](https://www.rust-lang.org/) compiler and standard library, Crowbook uses the following libraries: * [pulldown-cmark](https://crates.io/crates/pulldown-cmark) * [yaml-rust](https://crates.io/crates/yaml-rust) * [mustache](https://crates.io/crates/mustache) * [clap](https://github.com/kbknapp/clap-rs) * [chrono](https://crates.io/crates/chrono) * [uuid](https://crates.io/crates/uuid) * [mime_guess](https://crates.io/crates/mime_guess) * [crossbeam](https://crates.io/crates/crossbeam) * [walkdir](https://crates.io/crates/walkdir) * [rustc-serialize](https://crates.io/crates/rustc-serialize) It also embeds [Highlight.js](https://highlightjs.org/) in HTML output to enable syntax highlighting for code blocks. It also uses configuration files from [rust-everywhere](https://github.com/japaric/rust-everywhere) to use [Travis](https://travis-ci.org/) and [Appveyor](http://www.appveyor.com/) to generate binaries for various platforms on each release. While Crowbook directly doesn't use them, there was also inspiration from [Pandoc](http://pandoc.org/) and [mdBook](https://github.com/azerupi/mdBook). Also, the [W3C HTML validator](https://validator.w3.org/) and the [IDPF EPUB validator](http://validator.idpf.org/) proved very useful during development. ChangeLog --------- See [ChangeLog](ChangeLog.md). Library ------- While the main purpose of Crowbook is to be runned as a command line, the code is written as a library, so if you want to build on it you can use it as such. You can look at the generated documentation on [docs.rs](https://docs.rs/releases/search?query=crowbook).
