[編輯] Description

The template calls a specified template up to 150 times, where one parameter takes each of a list of values; in addition to the variable parameter, for up to 4 parameters a fixed value can be specified.

[編輯] Usage

{{for
  |call=template to call
  |sep=what to separate the entries with
  |pc1=parameter name=constant value
  |pc2=parameter name=constant value
  |pc3=parameter name=constant value
  |pc4=parameter name=constant value
  |pv=name of variable parameter
  |prefix=constant first part of the value of pv
  |postfix=constant last part of the value of pv
  |list of up to 150 parameter values (without prefixes and postfixes), with separator "|"
}}

  |sep=, 1
}}

Note that the last part of the separator is used as a prefix; the first prefix needs to be put separately.

{{for|a|3||c|call=x3|sep=-}} using Template:Tim gives

Template:X3-Template:X3-Template:X3-Template:X3

{{for|p|||3||c|call=t|sep=///}} using Template:Tim gives

Template:T///Template:T///Template:T///Template:T///Template:T///Template:T

{{for|call=short DOW|3|1|5|3|2|sep= / }} using Template:Tim gives

Template:Short DOW / Template:Short DOW / Template:Short DOW / Template:Short DOW / Template:Short DOW

{{for|call=t2|pc1=2=constant|abc|def|ghi}} using Template:Tim gives:

Template:T2Template:T2Template:T2

{{for|call=concat and link to w:en:|sep=, |pc1=John_|pv=2||Lennon|Wayne}} using Template:Timc gives Template:Concat and link to w:en:, Template:Concat and link to w:en:, Template:Concat and link to w:en:

A for-call can give a row or column of choice, e.g. using Template:Tim:

{{for|sep=,|2|3|call=power|prefix=2,}} gives Template:Power,Template:Power

{{for|sep=,|2|3|call=power|prefix=3,}} gives Template:Power,Template:Power

{{for|sep=,|2|3|call=power|postfix=,2}} gives Template:Power,Template:Power

{{for|sep=,|2|3|call=power|postfix=,3}} gives Template:Power,Template:Power

A constant parameter is ignored if it is the same as the (implicitly or explicitly given) variable parameter:

{{for|call=t2|pc1=1=7|pc2=2=5|abc|def|ghi|sep=,}} using Template:Tim gives:

Template:T2,Template:T2,Template:T2

{{for|sep=,|call=x3|1=a=b|2=c=d|3=e}} gives Template:X3,Template:X3,Template:X3

{{#expr:{{for|call=plus square|pv=1|1|2|3|4|5}}}} gives Expression error: Unrecognised punctuation character "[".

[編輯] Reserved name

A reserved name that cannot be used as list item is "@"; it is ignored, but e.g. @1 is not:

{{for|a|@|@1|b|c|call=x3|sep=-}} gives

Template:X3-Template:X3-Template:X3-Template:X3

[編輯] Related templates

This template is another version of Template:Tim. That version has stopped working due to some software change.

Comparison:

{{{v{{{2 }}}|{{{s }}}{{{{{c}}}|{{{pc1}}}|..|{{{pc4}}}|{{{pv}}}={{{2}}}}}}}}
{{{v{{{2|}}}|{{{s|}}}}}}{{{{{{{{v{{{2|}}}|c}}}|x0}}} |{{{pv}}}={{{2}}}|{{{pc1}}}|..|{{{pc4}}}}}

In the first case (for) the whole output is the default of a parameter named v{{{i }}} that is defined iff the ith parameter is not defined.

In the second case (foreach) the existence is checked twice, once for the separator and once for the main output; if the ith parameter is not defined a dummy template is called.

Both are based on Template:Tiw. Differences are:

• The Meta versions handle empty parameter values in the regular way, while the en version ignores them.
• Template For allows "=" in parameter values
• The difference in the case of conflicting parameter names, mentioned above.
