上篇说到用pandoc转换为reST为pdf是使用LaTeX作为中间格式的,而今天要说的rst2pdf貌似是直接转换为pdf的。

安装和调用

rst2pdf目前只支持Python2.7,因此在创建virtualenv时应使用-p选项指定2.7的python,即

mkvirtualenv -p /path/to/python2.7 rst
workon rst
pip install rst2pdf

最简单的调用方式是

rst2pdf xxx.rst

然后默认就会生成xxx.pdf文件,当然中文这要是不好使的,因为默认样式是不支持中文字体的,生成的pdf里,中文都是黑块。

中文样式

rst2pdf有一些默认的样式,base、bodytext等等,我们还可以自己新增样式,也可以修改默认的一些样式的选项。对样式的选项修改类似于css,后面的样式选项可以覆盖前面的样式选项,所以我们一般不会去直接修改默认样式,而是在我们自己的样式文件中,覆盖默认的选项,在生成pdf的时候,可以一次性指定多个样式,后面的会覆盖前面的。

对于中文来说,我们就差一个字体的样式了,具体来说就是把下面的代码存储成 chinese.style

{
  "embeddedFonts": [
    [
      "simfang.ttf",
      "simhei.ttf",
      "simkai.ttf",
      "simsun.ttc"
    ]
  ],
  "fontsAlias": {
    "stdFont": "simfang",
    "stdBold": "simhei",
    "stdItalic": "simkai"
  }
}

注:有关字体的配置参见官方文档,这个配置对Linux和Windows应该都是好使的,前提是这些字体文件是真实存在的。Linux字体文件在 /usr/share/fonts 和 ~/.local/share/fonts 文件夹中。

此时,运行以下命令, 中文就可以显示出来了

rst2pdf -s chinese.style xxx.rst

 

配置文件

如果样式需要每次都指定,对于中文来说就有点不方便,rst2pdf支持一个配置文件,可以使用 --config 的方式传递配置文件路径,默认的配置文件路径是 ~/.rst2pdf/config

以下是官方方式给的配置文件示例+我改了stylesheets,stylesheet_path,language

# This is an example config file. Modify and place in ~/.rst2pdf/config

[general]
# A comma-separated list of custom stylesheets. Example:
# stylesheets="fruity.json,a4paper.json,verasans.json"

stylesheets="chinese"

# Create a compressed PDF
# Use true/false (lower case) or 1/0
compressed=false

# A colon-separated list of folders to search for fonts. Example:
# font_path="/usr/share/fonts:/usr/share/texmf-dist/fonts/"

font_path=""

# A colon-separated list of folders to search for stylesheets. Example:
# stylesheet_path="~/styles:/usr/share/styles"
stylesheet_path="~/.rst2pdf/styles"

# Language to be used for hyphenation support

language="zh_CN"

# Default page header and footer
header=null
footer=null

# What to do if a literal block is too large. Can be
# shrink/truncate/overflow

fit_mode="shrink"

# How to adjust the background image to the page.
# Can be: "scale" and "center"

fit_background_mode="center"

# What is the maximum level of heading that starts in a new page.
# 0 means no level starts in a new page.

break_level=0

# How section breaks work. Can be "even", and sections start in an
# even page, "odd", and sections start in odd pages, or "any" and
# sections start in the next page, be it even or odd.

break_side="any"

# Add a blank page at the beginning of the document

blank_first_page=false

# Treat the first page as even (default false, treat it as odd)

first_page_even=false

# Smart quotes.
# 0:  Suppress  all  transformations. (Do nothing.)
# 1: Performs default SmartyPants transformations: quotes (including ‘‘backticks''
# -style), em-dashes, and ellipses. "--" (dash dash) is used to signify an em-dash;
# there is no support for en-dashes.
# 2:  Same as 1, except that it uses the old-school typewriter shorthand for
# dashes: "--" (dash dash) for en-dashes, "---" (dash dash dash) for em-dashes.
# 3: Same as 2, but inverts the shorthand for dashes: "--" (dash dash) for
# em-dashes,  and "---" (dash dash dash) for en-dashes.

smartquotes=0

# Footnote backlinks enabled or not (default: enabled)

footnote_backlinks=true

# Show footnotes inline instead of at the end of the document

inline_footnotes=false

# Cover page template.
# It will be searched in the document's folder, in ~/.rst2pdf/templates and
# in the templates subfolder of the package folder

# custom_cover = cover.tmpl

# Use floating images.
# Makes the behaviour of images with the :align: attribute more like rst2html's

floating_images = false

# Support the ..raw:: html directive
raw_html = false

 使用以上的配置文件,我们需要将刚刚的 chinese.style 放到 ~/.rst2pdf/styles/ 文件夹中,以后再生成pdf的时候,就可以简单的使用和英文相同的方式了

rst2pdf xxx.rst

 默认设置下,rst2pdf的效果貌似要比pandoc的要好,以后不太要求的文档就用这个好了,长篇文档,估计还得使用sphinx
