Harper Can Apply Title Case

In case you did­n’t know: Harper can con­vert text to ti­tle case! This has been around for a long time, but we haven’t re­ally talked about it pub­licly. Be­ing able to make text ti­tle case (strictly in ac­cor­dance to Chicago Style) is­n’t a ground­break­ing fea­ture, but it is use­ful for cer­tain niche ap­pli­ca­tions.

For ex­am­ple, all the ti­tles in this very blog are forced to ti­tle case on pub­lish, which is­n’t some­thing most CMS sys­tems do. I’d love to see it be­come more wide­spread.

We have a live demo where you can try it out. It’s also avail­able as part of harper.js, our JavaScript pack­age.

Soon, this will be­come a part of Harper’s na­tive lint­ing ca­pa­bil­i­ties.
