TWiki Spreadsheet Plugin

This plugin adds spreadsheet capabilities to TWiki topics. Functions such as %CALCULATE{$INT(7/3)}% are evaluated at page view time. They can be placed in table cells and outside of tables. In other words, this plugin provides general function evaluation capability, not just classic spreadsheet functions. The plugin currently has 123 functions.

Example:

Region: Sales:
Americas 732
Europe 611
Asia 228
Total: 1571
  Raw text:

| *Region:* | *Sales:* |
| Americas  |  732 |
| Europe    |  611 |
| Asia      |  228 |
| Total: |  %CALC{$SUM($ABOVE())}% |

Interactive example:

%CALCULATE{ }%
Result:  TWiki Guest

Syntax Rules

This plugin handles the %CALC{...}% and %CALCULATE{...}% variables. Embedded formulas are evaluated as follows:

Use CALC or CALCULATE

Table Use %CALC{...}% in table cells:
The CALC variable handles all functions, but it gets handled with delay compared to other TWikiVariables: It gets executed after internal variables and plugin variables that use the register tag handler. You may get unexpected results if you nest CALC inside other variables (such as %INCLUDE{%CALC{...}%}%) because it does not get evaluated inside-out & left-to-right like ordinary TWiki variables.

Index list Use %CALCULATE{...}% outside tables:
The CALCULATE variable is handled inside-out & left-to-right like ordinary TWiki variables, but it does not support functions that refer to table cells, such as $LEFT() or $T().

FAQ

Can I use CALCULATE in a formatted search?

Specifically, how can I output some conditional text in a FormattedSearch?

You need to escape the CALCULATE so that it executes once per search hit. This can be done by escaping the % signs of %CALCULATE{...}% with $percnt. For example, to execute $IF($EXACT($formfield(Tested), Yes), %ICONURL{choice-yes}%, %ICONURL{choice-no}%) in the format="" parameter, write this:

%SEARCH{ .... format="| $topic | $percntCALCULATE{$IF($EXACT($formfield(Tested), Yes), %ICONURL{choice-yes}%, %ICONURL{choice-no}%)}$percnt |" }%

What are hashes and what are they used for?

Hashes are named sets of key & value pairs. For example, a hash called age may have first names as keys and ages as values. In TWiki's case you might do a FormattedSearch and store the result in hashes, then display the result in various formats. For example, you want to show feature requests in multiple tables, organized by status. Adding a search for each status is possible, but it can be slow. The page loads faster if you search only once, and store the status, summary, date and other fields in hashes. Then you use those hashes to render each table by status.

Example:

%CALCULATE{$SETHASH()}% <!-- clear all hashes -->
%SEARCH{
 "form.name='FeatureForm'"
 type="query"
 nonoise="on"
 format="$percntCALCULATE{$SETHASH(status, $topic, $formfield(Status))$SETHASH(summary, $topic, '''$summary''')$SETHASH(date, $topic, '''$date''')}$percnt"
}%
---++ Proposed Features
| *Feature* | *Updated* |
%CALCULATE{
  $LISTJOIN(
    $n,
    $LISTEACH(
      | [[$item]]: $GETHASH(summary, $item) | $GETHASH(date, $item) |,
      $LISTIF(
        $EXACT(
          $GETHASH(status, $item),
          Proposed
        ),
        $GETHASH(status)
      )
    )
  )
}%
---++ Accepted Features
| *Feature* | *Updated* |
%CALCULATE{
  $LISTJOIN(
    $n,
    $LISTEACH(
      | [[$item]]: $GETHASH(summary, $item) | $GETHASH(date, $item) |,
      $LISTIF(
        $EXACT(
          $GETHASH(status, $item),
          Accepted
        ),
        $GETHASH(status)
      )
    )
  )
}%

First we search all features and store the status, summary and date in hashes, using the topic name as the key. Then we build a table that shows all proposed features, followed by a table showing all accepted features. Reading the CALCULATE formula from inside out:

How can I easily repeat a formula in a table?

To repeat the same formula in all cells of a table row define the formula once in a preferences setting and use that in the CALC. The preferences setting can be defined at the site level, web level or topic level, and may be hidden in HTML comments. Example:

<!--
   * Set MYFORMULA = $EVAL($SUBSTITUTE(...etc...))
-->
| A | 1 | %CALC{%MYFORMULA%}% |
| B | 2 | %CALC{%MYFORMULA%}% |
| C | 3 | %CALC{%MYFORMULA%}% |

CALC in Included Topics

By default, CALCs in an included topic are evaluated with delay. The SKIPINCLUDE setting tells the plugin to evaluate the CALCs once all INCLUDEs are processed. This default behavior is chosen so that it is possible to compose a bigger table from several includes and do some spreadsheet calculation over the whole table.

ALERT! Attention: You can get unexpected results if you INCLUDE a topic that has other variables taking action on CALCs. For example, a CHART in an included topic sees unprocessed CALCs, which may result in a chart with incorrect values. To get he desired result you need to set the following preference setting in the topic that includes the topic containing the CHART:

This setting tells the SpreadSheetPlugin to process the CALCs in the included page, e.g. it will not delay the evaluation of the functions.

Bug Tracking Example

Bug#: Priority: Subject: Status: Days to fix
Bug:1231 Low File Open ... Open 3
Bug:1232 High Memory Window ... Fixed 2
Bug:1233 Medium Usability issue ... Assigned 5
Bug:1234 High No arrange ... Fixed 1
Total: 4 High: 2
Low: 1
Medium: 1
. Assigned: 1
Fixed: 2
Open: 1
Total: 11

The last row is defined as:

| Total: %CALC{$ROW(-2)}% \ 
  | %CALC{$COUNTITEMS( R2:C$COLUMN()..R$ROW(-1):C$COLUMN() )}% | . \ 
  | %CALC{$COUNTITEMS( R2:C$COLUMN()..R$ROW(-1):C$COLUMN() )}% \ 
  |  Total: %CALC{$SUM( R2:C$COLUMN()..R$ROW(-1):C$COLUMN() )}% |

Above table is created manually. The table can be build dynamically with a formatted search, or by a plugin that pulls data from an external source, such as a bug tracking system.
