insertDoubleHash: Add a double hash comment

In cvanderaa/customAddins:

Description

The function inserts or removes two hashes and a space ("## ") at the beginning of a line. It also works for multiple line. The function is meant to behave similarly to the Rstudio built-in Comment / Uncomment Selection tool (see Details for an comprehensive description).

Usage

insertDoubleHash()

Details

The function has two behaviors depending on the current selection in the document:

• The current selection spans a single line. Different scenarios

  • The line doesn't start with "#" (ignoring leading spaces): the "## " is inserted after the leading space

  • The line starts with "## " (ignoring leading spaces): the leading "## " is removed

  • The line start with a regular comment "#" (ignoring leading spaces): the comment ("# " or "#") is replaced by "## ". For roxygen2 comments "#'" nothing happen.

• The current selection spans multiple lines:

  • Any of the lines don't start with "#" (ignoring leading spaces): the "## " is inserted after the smallest leading space for all lines. For roxygen2 comment "#'" nothing happen.

  • All lines start with "## " (ignoring leading spaces): all leading "## " are removed.
