| ==Parser functions==
| | {{DEFAULTSORT:{{SUBPAGENAME}}}} |
| ''These are fully documented at the [[mw:Help:Magic words|Meta magic words page]] or [[mw:Help:Extension:ParserFunctions|ParserFunctions Extension documentation]] unless otherwise stated.''
| | [[Category:AT Sourcebook subpages]] |
| | | [[Category:Appropriate_technology]] |
| ===Conditional expressions===
| | [[Category:Food and agriculture]] |
| These are covered at the [[mw:Help:Extension:ParserFunctions|extension documentation page]]. Some parameters are optional.
| | [[Category:Agriculture]] |
| *<tt><nowiki>{{#expr:</nowiki> ''expression'' <nowiki>}}</nowiki></tt> (evaluates the given expression; see [[Help:Calculation]])
| | </noinclude> |
| *<tt><nowiki>{{#if:</nowiki> ''test string'' | ''value if non-empty'' | ''value if empty'' <nowiki>}}</nowiki></tt> (selects one of two values based on whether the test string is empty)
| |
| *<tt><nowiki>{{#ifeq:</nowiki> ''string 1'' <nowiki>|</nowiki> ''string 2'' <nowiki>|</nowiki> ''value if equal'' <nowiki>|</nowiki> ''value if unequal'' <nowiki>}}</nowiki></tt> (selects one of two values based on whether the test strings are equal – numerically if applicable)
| |
| *<tt><nowiki>{{#iferror:</nowiki> ''test string'' <nowiki>|</nowiki> ''value if error'' <nowiki>|</nowiki> ''value if correct'' <nowiki>}}</nowiki></tt> (selects value based on whether the test string generates a parser error)
| |
| *<tt><nowiki>{{#ifexpr:</nowiki> ''expression'' <nowiki>|</nowiki> ''value if true'' <nowiki>|</nowiki> ''value if false'' <nowiki>}}</nowiki></tt> (selects value based on evaluation of expression)
| |
| *<tt><nowiki>{{#ifexist:</nowiki> ''page title'' | ''value if exists'' | ''value if doesn't exist'' <nowiki>}}</nowiki></tt> (selects value depending on whether a page title exists)
| |
| *<tt><nowiki>{{#switch:</nowiki> ''test'' | ''case1'' = ''value for case 1'' | ... | ''default'' <nowiki>}}</nowiki></tt> (provides alternatives based on the value of the test string)
| |
| | |
| Note that with <code>#if:</code> expressions, a variable like <code><nowiki>{{{1}}}</nowiki></code> always requires a final pipe: <code><nowiki>{{{1|}}}</nowiki></code>. If it is absent, then whenever the parameter 1 is absent, instead of leaving the field blank the software will use the actual text ''<code>{{{1}}}</code>'' and the field will never be empty.
