One of the most frequent topics on which I blog in recent years is Chinese literature (of course, only in my Chinese blog). In particular, I often quote poems in my posts. To quote a poem in Markdown, you have to add two trailing spaces after every line of the poem. Two trailing spaces means a hard line break in Markdown. A line break in the Markdown source does not mean a line break in the output (usually white spaces are not meaningful in Markdown).
I have been tired of manually adding the trailing spaces (also > to the beginning of every paragraph) . Finally I wrote a tiny function quote_poem() in blogdown to do this. The function was not exported, but that should be fine, because I also provided a corresponding RStudio addin named “Quote Poem”. Currently this feature is only available in the development version of blogdown. The usage of the addin is simple: just select the poem in the RStudio source editor, and click the addin. For example, if you paste a poem in RStudio:
Like Barley Bending
by Sara Teasdale
Like barley bending
In low fields by the sea,
Singing in hard wind
Ceaselessly;
Like barley bending
And rising again,
So would I, unbroken,
Rise from pain;
So would I softly,
Day long, night long,
Change my sorrow
Into song.
You can select it, and click the addin, which will generate the expected output below:
Like Barley Bending
by Sara TeasdaleLike barley bending
In low fields by the sea,
Singing in hard wind
Ceaselessly;Like barley bending
And rising again,
So would I, unbroken,
Rise from pain;So would I softly,
Day long, night long,
Change my sorrow
Into song.
I guess blogdown users might be surprised by this function/addin the first time they see it. Poems… and blogdown? How can an R package be possibly related with poems?!
Yes, I just care that much about blogging, and want to improve at least my own writing experience by one little function at a time.
