Highlight indentation with bars
indent-bars highlights indentation with configurable vertical graphical bars, using stipples. The color and appearance (weight, pattern, position within the character, zigzag, etc.) are all configurable. Options include depth-varying colors and highlighting the indentation depth of the current line. Bars span blank lines, by default. indent-bars works in any mode using fixed tab or space-based indentation. In the terminal (or on request) it uses vertical bar characters instead of stipple patterns. Optional treesitter support is also available; see indent-bars-ts.el. For Developers: To efficiently accommodate simultaneous alternative bar styling, we do two things: 1. Collect all the style related information (color, stipple pattern, etc.) into a single struct, operating on one such "current" style struct at a time. 2. Provide convenience functions for duplicate "alternative" custom style variables the user can configure; see `indent-bars--style'. These variables can "inherit" nil or omitted plist variables from their parent var. Note the shorthand substitution for style related slots; see file-local-variables at the end: ibs/ => indent-bars-style-
