Description

This library implements a table with the following functionalities:

• Search

  User can filter data based on regular expressions. The columns are separated by #{column number}#. For example, when you want to search in the third column you type : #3#{regular expression}

• Pagination

  It defines which entries should appeared on the screen.The default number of entries a page can show is 10. User can change this using the selection box. It also offers the ability to navigate through pages.

• Sort

  User can sort the table based on the column he clicks. Sorting is performed using a permutation table. The list doesn't change so the original sequence can be restored

Example

You can run the example using the following command:

git clone https://github.com/zgeorg03/table-elm.git && cd table-elm && elm-reactor

Implementation

The library is divided into the following components:

• Value

  Defines all the possible types used by the other modules.

• Cell

  Represents a single cell of the table. Its value can be hidden.

• Record

  Represents one entry in a table. It uses a list of cells.

• Header

  Represents the header of the table. It controls the state of each column. State can be ascending,descending or original( as given).

• Pagination

  Controls the view of the table. It breaks the view into pages showing a specified number of records.

• Search

  During initialization the list of data is provided. The user can filter the data using regular expressions.

• Table

  Table connects all the components together, providing them the data.

• Native/SafeRegex

  A clone of regex module provided by elm/core package, with a new function that returns a Result instead of a Regex. This is necessary because the user types custom regular expressions and the regex module doesn't provide a way to avoid program crash.

Further Work

1. Column should know the data type not the cell
2. Take into consideration evancz/elm-sortable-table implementation in order to generalize this library in a better way.
