Module:Separated entries/sandbox
This is the module sandbox page for Module:Separated entries (diff). See also the companion subpage for test cases (run). |
This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing. |
This Lua module is used on approximately 2,430,000 pages, or roughly 4% of all pages. To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them. |
This module depends on the following other modules: |
Usage
[edit]Module:Separated entries serves as a template front-end to mw.text.listToText
. It takes any number of positional parameters and pieces them together with |separator=
. |conjunction=
can be optionally defined if a different separator is desired between the last and second last items. The starting positional parameter can be specified using |start=
. Leading and trailing whitespace is stripped. To add deliberate leading and trailing whitespace, use the HTML entity  
for a space and
for a "newline". Separated entries does not raise any errors by design.
{{#invoke:separated entries|main|separator=...}}
For more complex cases – such as selecting the parameters to list, or preprocessing them, or omitting the last parameters – {{#invoke:params|list_values}} is available. The following two examples with “ + ” as delimiter and “ ... ” as conjunction produce a similar result:
{{#invoke:separated entries|main|separator= + |conjunction= ... }}
{{#invoke:params|sequential|squeezing|trimming_values|setting|i/l| + | ... |list_values}}

-- This module takes positional parameters as input and concatenates them with
-- an optional separator. The final separator (the "conjunction") can be
-- specified independently, enabling natural-language lists like
-- "foo, bar, baz and qux". The starting parameter can also be specified.
