Hexo will add extra space of continous lines with CJK characters.
.....中文结尾
中文顶格...
will result in
.....中文结尾 中文顶格...
`- note the space here
This plugin will fix that.
Usage
$ npm install hexo-filter-fix-cjk-spacing --save
If you want to disable this plugin, add the following line in your
_config.yml
:
fix_cjk_spacing: false
Note that Hexo' marked.js
uses GitHub flavored markdown which will parse every line break in markdown
into <br>
. Use the following to disabled it:
marked: breaks: false
The problem
In markdown, if we write several lines continuously, it will be parsed as a whole block:
line 1
line 2
line 3
// will be parsed as
<p>line 1
line 2
line 3</p>
That means line breaks are kept and all the three lines are treated as a whole paragraph.
However, the browser will convert the line break in a <p>
into a single
space, so when we see the previous content in a browser, it will look like:
line 1 line 2 line 3
That is OK except when we use Chinese. There is no concept of space in Chinese, so when we write:
中文第一行
中文接上行
// will show as
中文第一行 中文接上行
// `- not the space here
It is really frustrating! So there are two major solutions:
- Fixing the markdown parsing code to treat it correctly.
- Write the whole paragraph in a long line.
The first option is actually not so pratical. This 'bug' exist for so long and still not fixed. The second will be so boring and un-friendly.
So here comes our solution with hexo
: Write a filter to merge chinese lines
automatically before parsing!
The use case
Only the following situation are dealt with:
...<chinese character>[should contains no spaces]
[zero or more spaces|tab]<chinese character>
.....中文结尾
中文顶格...
// are modified to
.....中文结尾中文顶格...
// `- note no space here
Note that the content in fenced code block will not be changed. But indented code blocks will be changed
