模板:Conditional template call with newline
該模版在條件{{{1}}}下調用模版{{{2}}}並使用參數{{{3}}}，且在結尾添加一個換行符。
該模板用於避免兩次寫出條件：一次用於模板調用，一次用於換行。Template:If可用於保留換行符。
用法
Sample 1
Example using Template:2x, which simply repeats its argument twice, so {{2x|Pizza}} produces PizzaPizza. One can combine this with {{Conditional template call with newline}} in the following code
{{#tag:pre|{{Conditional template call with newline|1|2x|Pizza}}{{Conditional template call with newline|0|2x|Bora}}{{Conditional template call with newline|1|2x|Bang}}}}
- which produces
PizzaPizza BangBang
Notice how BoraBora is suppressed, and there is a newline between PizzaPizza and BangBang.
Sample 2
Example using {{Table row Dutch municipality}}
{| class="wikitable sortable"
!Municipality!!Population
{{Conditional template call with newline|1|Table row Dutch municipality|Delft}}{{Conditional template call with newline|0|Table row Dutch municipality|Hoorn}}{{Conditional template call with newline|1|Table row Dutch municipality|Rotterdam}}|}
gives
| Municipality | Population
Template:Table row Dutch municipality Template:Table row Dutch municipality |
|---|
The template is typically called by another table row template, which has as parameter {{{1}}} the identification of the potential item (in this template: {{{3}}}), and some parameter {{{2}}} related to the condition. That template provides the condition in terms of {{{1}}} and {{{2}}}.
Sample 3
Sample usage with full substitution of the template to create a newline in wikitext.
1. Create a sample template : "Template:testnewline"
ABC{{<includeonly>subst:</includeonly>Conditional template call with newline|{{<includeonly>subst:</includeonly>#ifeq:{{{align|}}}|{{{align}}}|1|0}}|void|1|substctc=subst:|subst=subst:}}
DEF
2. When called empty ({{subst:testnewline}}), it generates the following wikitext:
ABC DEF
3. When called as {{subst:testnewline|align=somevalue}}, it generates the following wikitext (note the newline):
ABC DEF
參數
必選參數
- 1
- 第一個未命名參數，用於判斷條件。其中1代表真（True），而0代表假（False）。如果條件為真，那麼第二個模板將被調用，並在結尾添加一個換行符。可直接輸入0或1。
示例：{{#ifeq:{{{align|}}}|{{{align}}}|1|0}}。當一個模板被調用，且使用align為任意值的參數時條件為真：而align未包含時條件為假。 - 2
- 第二個未命名參數，為需要調用模板的名稱。
可使用Template:!代替「!」，Template:Void代替「void」。
可選參數
- 3
- 3rd unnamed parameter, value to be assigned to {{{1}}} when calling template {{{2}}}
- substctc
- for substitution of some parser functions and auxiliary templates called inside the template, use the value "subst:"; recommended when the template is substituted; note that in that case any parser functions or templates in the condition have to be substituted too.
- subst
- for substitution of template {{{2}}}, use the value "subst:"
- p1n
- name of an additional parameter used by template {{{2}}}
- p1v
- value to be assigned to {{{p1n}}} when calling template {{{2}}}
