---+!! TWiki Spreadsheet Plugin <!-- Contributions to this plugin are appreciated. Please update the plugin page at http://twiki.org/cgi-bin/view/Plugins/SpreadSheetPlugin or provide feedback at http://twiki.org/cgi-bin/view/Plugins/SpreadSheetPluginDev. If you are a TWiki contributor please update the plugin in the SVN repository. --> This plugin adds spreadsheet capabilities to TWiki topics. Formulae like ==%<nop>CALC{"$INT(7/3)"}%== are evaluated at page view time. They can be placed in table cells and outside of tables. In other words, this plugin provides general formula evaluation capability, not just classic spreadsheet functions. <table><tr><td valign="top"> __Example:__ | *Region:* | *Sales:* | | Northeast | 320 | | Northwest | 580 | | South | 240 | | Europe | 610 | | Asia | 220 | | Total: | %CALC{"$SUM( $ABOVE() )"}% | </td><td>&nbsp; &nbsp; &nbsp;</td><td valign="top"> __Interactive example:__ <form name="interactive" action="%SCRIPTURL%/view%SCRIPTSUFFIX%/%WEB%/%TOPIC%" method="get"> <noautolink> Formula: <code>%<nop>CALC{"</code><input type="text" name="formula" size="40" value="%URLPARAM{ "formula" default="$PROPERSPACE(%WIKINAME%)" encode="entity" }%" class="twikiInputField" /><code>"}%</code> <input type="submit" value="Evaluate" class="twikiSubmit" /><br /> Result: &nbsp; &nbsp; %CALC{%URLPARAM{ "formula" default="$PROPERSPACE(%WIKINAME%)" }%}% </noautolink> </form> </td></tr><tr><td colspan="3"> The formula next to "Total" is ==%<nop>CALC{"$SUM( $ABOVE() )"}%==. <br /> (you see the formula instead of the sum in case the plugin is not installed or not enabled.) </td></tr></table> %TOC% ---++ Syntax Rules The action of this plugin is triggered by the ==%<nop>CALC{"..."}%== variable, which gets rendered according to the built-in function(s) found between the quotes. * Built-in function are of format ==$FUNCNAME(parameter)== * Functions may be nested, such as ==%<nop>CALC{"$SUM( R2:C$COLUMN(0)..R$ROW(-1):C$COLUMN(0) )"}%== * Functions are evaluated from left to right, and from inside to outside if nested * The function parameter can be text; a mathematical formula; a cell address; or a range of cell addresses * Multiple parameters form a list; they are separated by a comma, followed by optional space, such as ==%<nop>CALC{"$SUM( 3, 5, 7 )"}%== * A table cell can be addressed as ==R1:C1==.

Specifically, how can I output some conditional text in a %SYSTEMWEB%.FormattedSearch? You need to escape the CALC so that it executes once per search hit. This can be done by escaping the =%= signs of =%<nop>CALC{...}%= with =$percnt=. For example, to execute =$IF($EXACT($formfield(Tested), Yes), %<nop>PUBURL%/%<nop>SYSTEMWEB%/TWikiDocGraphics/choice-yes.gif, %<nop>PUBURL%/%<nop>SYSTEMWEB%/TWikiDocGraphics/choice-no.gif)= in the =format=""= parameter, write this: =%<nop>SEARCH{ .... format="| $topic | $percntCALC{$IF($EXACT($formfield(Tested), Yes), %<nop>PUBURL%/%<nop>SYSTEMWEB%/TWikiDocGraphics/choice-yes.gif, %<nop>PUBURL%/%<nop>SYSTEMWEB%/TWikiDocGraphics/choice-no.gif)}$percnt |" }%= ---+++ 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: <verbatim> <!-- * Set MYFORMULA = $EVAL($SUBSTITUTE(...etc...)) --> | A | 1 | %CALC{%MYFORMULA%}% | | B | 2 | %CALC{%MYFORMULA%}% | | C | 3 | %CALC{%MYFORMULA%}% | </verbatim> #CalcInINCLUDE ---++ 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. __%X% Attention:__ You can get unexpected results if you [[%SYSTEMWEB%.VarINCLUDE][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: * Set <nop>SPREADSHEETPLUGIN_SKIPINCLUDE = 0 This setting tells the !SpreadSheetPlugin to process the CALCs in the included page, e.g. it will not delay the evaluation of the formulae. ---++ 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: %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$COLUMN() )"}% | The last row is defined as: <verbatim> | Total: %CALC{"$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() )"}% | </verbatim> Above table is created manually.
