Reflow is a Light Table plugin that allows you to reflow paragraphs to a fixed width. It is available in the Light Table plugin repository, or you can clone this repository into your plugins folder.
Reflow provides a new command called Reflow paragraph. Without a
selection, it acts on the current paragraph, as defined below. With a
selection, it acts on all the lines that are part of the selection
(including unselected text on those lines). The width of the reflowed
paragraph is set in your user.behaviors file:
{:+ {:editor [(:lt.plugins.reflow/set-width 72)]}}You can add a key binding for the reflow command by adding to your
user.keymap file:
{:+ {:editor {"ctrl-j" [:lt.plugins.reflow/reflow]}}}If all the lines begin with an identical prefix of symbols and whitespace, that prefix is stripped from all lines prior to reflowing and is prepended to all lines after the reflowing. This means that reflow works with most styles of comments. Whitespace is maintained, except at the ends of lines. All whitespace at the end of a line is compressed to a single space before the reflow, and no whitespace is left at the ends of lines after the reflow.
Reflow considers paragraphs to be sequential lines, all of which contain an alphanumeric character (A-Z, a-z, 0-9, or any non-ASCII unicode character). This means that most block comment sequences will delimit paragraphs if they occur on their own line. Additionally, if the current line begins with a line comment sequence, only lines that begin with that sequence will be included in the paragraph. (Note that this restriction does not work the other way; a paragraph selected from an uncommented line may include commented lines.)
