With this tool, one can define pieces of a notebook that belong to teachers and should not be exposed to students.

Project description

nbprune

typical use case is, a teacher writes a notebook, with solution(s) to a problem that students must solve
so this means 2 versions, one for the teacher(s) with the solutions, and one for the students
this tool defines annotations that the teacher can use to define the parts that will be automatically removed by the tool

keywords

here are the recognized keywords

tag meaning
prune-cell remove this cell from the output
prune-begin remove this cell and the ones below from the output
prune-end remove this cell, but resume insertion on the next cell
prune-begin-next (*) keep this cell from the output, and start pruning at the next one
prune-end-previous (*) stop pruning, and insert the current cell
prune-line (*) remove just that one line from the output
prune-line-begin (**) remove that line and the following ones
prune-line-end (**) remove that line but the following ones will show up

NOTES

  • (*) because prune-begin-next and prune-end-previous appear in a cell that is visible, the whole line containing the tag is removed from the output, so it is probably best to keep these tags on a separate line
  • (**) prune-line variants of course are not relevant, and are ignored, if set in the cell's metadata tags

line format

the tool will consider a tag is present in a cell if any line in the cell contains one of the above keywords, with the beginning of the line containing only # and spaces or tabs

so for exemple

line match
prune-cell yes
# prune-cell yes
# # prune-cell yes
some code prune-cell no

cell metadata

the tags can also be set in the cell's metadata as well (except for prune-line) ; something like this

{
  "tags": [
    "prune-cell"
  ]
}

examples

so that these 2 scenarios are equivalent

cell tag preserved
1 y
2 prune-cell n
3 y
4 y
5 prune-begin-next y
6 n
7 n
8 n
9 prune-end-previous y
10 y

or


cell tag preserved
1 y
2 prune-cell n
3 y
4 y
5 y
6 prune-begin n
7 n
8 prune-end n
9 y
10 y
