Unsemantic linewrapping - 818 entries

[Inspired by a blog post I read: https://scott.mn/2014/02/21/semantic_linewrapping/. Text adapted.] Sometimes when editing a Markdown file, I wrap the lines semantically. Instead of inserting a newline at 70 columns (or whatever), or making paragraphs one long line, I put in newlines at a point that seems logical to me. This may seem silly, but it produces better diffs. Semantic linewrapping also makes editing snappier. I can delete, edit or insert sentences easily using linewise operations. Code-oriented text editors like Vim and [REDACTED] are really good at this kind of manipulation. Editing text that hasn't been wrapped semantically is a pain, though:

Change The Perspective - 36 entries

This is a go game recodes file(.sgf file, refer to http://www.red-bean.com/sgf/). It base on such a coordinate system: in vertical direction, is from top(farthest end) to bottom, mark as a,b,c,...,s(19*19 board); in horizontal direction, is from left to right, uses the same notations. For Example, the coordinate notation 'cq', is the position at the bottom-left corner(vertical coordinate first). The record is from one player's perspective. We need to change to another's, but we don't want to change coordinate system, let it keep top to bottom and left to right. so we have to change the coordinates, a <-> s, b <-> r,c <-> q, etc. the Position 'cq', as transformation, it will be 'qd'.
