This verison was a quick implementation to solve a specific problem. It lives on (with many new features) as an npm module at pulibrary/page_label_generator.

Page Label Generator

Study to implement https://github.com/pulibrary/plum/issues/7

Requires

Known to work w/ Node 13.12.0

Install

$ npm install

You might also want to install babel-cli globally:

$ npm install --global babel-cli

Test

$ npm test

Transpile to es5

babel src --out-dir lib

Examples in the babel-node shell

$ babel src --out-dir lib
$ babel-node

Basic Numbering

> let mod = require("./lib/labelGen");

> let gen = mod.pageLabelGenerator();
> gen.next().value;
'1'
> gen.next().value;
'2'
> gen.next().value;
'3'

> let gen = mod.pageLabelGenerator(5, "paginate", "", "", "", "p. ", true);
> gen.next().value;
'[p. 5]'
> gen.next().value;
'[p. 6]'
> gen.next().value;
'[p. 7]'
> gen.next().value;
'[p. 8]'

Foliation

> let mod = require("./lib/labelGen");

> let gen = mod.pageLabelGenerator(42, "foliate", " r", " v", "", "f. ", false);
> gen.next().value;
'f. 42 r'
> gen.next().value;
'f. 42 v'
> gen.next().value;
'f. 43 r'
> gen.next().value;
'f. 43 v'

> let gen = mod.pageLabelGenerator(42, "foliate", "r", "v", "back", "f. ", true);
> gen.next().value;
'[f. 42v]'
> gen.next().value;
'[f. 43r]'
> gen.next().value;
'[f. 43v]'
> gen.next().value;
'[f. 44r]'
> gen.next().value;
'[f. 44v]'
