| |
| *
| |
| * Description:
| |
| * Adds highlighting to tables
| |
| *
| |
| * History:
| |
| * - 1.0: Row highlighting - Quarenon
| |
| * - 1.1: Update from pengLocations.js v1.0 - Quarenon
| |
| * - 2.0: pengLocations v2.1, Granular cookie - Saftzie
| |
| * - 2.1: Made compatible with jquery.tablesorter - Cqm
| |
| * - 2.2: Switch to localStorage - Cqm
| |
| * - 3.0: Allow cell highlighting - mejrs
| |
| *
| |
| * @todo Allow the stored data to be coupled to the table in question. Currently the data is stored
| |
| * on the page itself, so if any tables are shuffled, the highlighting doesn't follow. For
| |
| * the same reason tables hosted on other pages are not synchronized.

| /**
| |
| * DATA STORAGE STRUCTURE
| |
| * ----------------------
| |
| *
| |
| * In its raw, uncompressed format, the stored data is as follows:
| |
| * {
| |
| * hashedPageName1: [
| |
| * [0, 1, 0, 1, 0, 1],
| |
| * [1, 0, 1, 0, 1, 0],
| |
| * [0, 0, 0, 0, 0, 0]
| |
| * ],
| |
| * hashedPageName2: [
| |
| * [0, 1, 0, 1, 0, 1],
| |
| * [1, 0, 1, 0, 1, 0],
| |
| * [0, 0, 0, 0, 0, 0]
| |
| * ]
| |
| * }
| |
| *
| |
| * Where `hashedPageNameX` is the value of wgPageName passed through our `hashString` function,
| |
| * the arrays of numbers representing tables on a page (from top to bottom) and the numbers
| |
| * representing whether a row is highlighted or not, depending on if it is 1 or 0 respectively.
| |
| *
| |
| * During compression, these numbers are collected into groups of 6 and converted to base64.
| |
| * For example:
| |
| *
| |
| * 1. [0, 1, 0, 1, 0, 1]
| |
| * 2. 0x010101 (1 + 4 + 16 = 21)
| |
| * 3. BASE_64_URL[21] (U)
| |
| *
| |
| * Once each table's rows have been compressed into strings, they are concatenated using `.` as a
| |
| * delimiter. The hashed page name (which is guaranteed to be 8 characters long) is then prepended
| |
| * to this string to look something like the following:
| |
| *
| |
| * XXXXXXXXab.dc.ef
| |
| *
| |
| *
| |
| * The first character of a hashed page name is then used to form the object that is actually
| |
| * stored. As the hashing function uses hexadecimal, this gives us 16 possible characters (0-9A-Z).
| |
| *
| |
| * {
| |
| * A: ...
| |
| * B: ...
| |
| * C: ...
| |
| * // etc.
| |
| * }
| |
| *
| |
| * The final step of compression is to merge each page's data together under it's respective top
| |
| * level key. this is done by concatenation again, separated by a `!`.
| |
| *
| |
| * The resulting object is then converted to a string and persisted in local storage. When
| |
| * uncompressing data, simply perform the following steps in reverse.
| |
| *
| |
| * For the implementation of this algorithm, see:
| |
| * - `compress`
| |
| * - `parse`
| |
| * - `hashString`
| |
| *
| |
| * Note that while rows could theoretically be compressed further by using all ASCII characters,
| |
| * eventually we'd start using characters outside printable ASCII which makes debugging painful.
