rst2pdf 中文
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
