This module depends on the following other modules: Module:String (sandbox) Module:TableTools (sandbox) Module:Yesno (sandbox)

Implements template {{Str find word}}.

This module looks for a word being present in a comma-separated list of words. It then returns a True or False value. By default, the True-value returned is the found word itself; the False-value is a blank string.

For example, in the source string 'foo, bar' the word 'bar' appears, but the word 'november' does not.

{{#invoke:Str find word |main |source=foo, bar |word=bar}} (True) → bar

{{#invoke:Str find word |main |source=alpha, beta, gamma |word=november}} (False) →

Multiple word check: The search can be extended to check for multiple words being present.

AND-list of words, all words must be present:

{{#invoke:Str find word |main |source=alpha, beta, gamma |andwords=beta, alpha}} (True) → beta,alpha

{{#invoke:Str find word |main |source=alpha, beta, gamma |andwords=beta, omega}} (False) →

OR-list of words, at least one off the words must be present:

{{#invoke:Str find word |main |source=alpha, beta, gamma |orwords=beta, alpha}} (True) → beta,alpha

{{#invoke:Str find word |main |source=alpha, beta, gamma |orwords=beta, omega}} (False) → beta

Complete words: the complete word is 'foobar' (example needed) Whitespace is trimmed,

The module is aimed at template code usage. (The editor does not have to apply Lua patterns like [%a%d]*). }}

Main parameters (including their synonyms)

{{Str find word
|source= s=
 |word= andwords= andw=
 |orwords= orw=
|case=
|out-true=
|out-false=
}}

{{Str find word |s= |w= |andw= |orw= |case= |out-true= |out-false=}}

{{Str find word
|source =
|word   =
}}

{{Str find word |source=cow, horse, dog, fish |word=dog}} (True) → dog

{{Str find word |source=cow, horse, dog, fish |word=cat}} (False) →

When the word is found in the source (True), the function returns the word itself (by default), or |out-true= value (when entered non-empty).

When not found (False), the function returns a empty string (''), or the |out-false= value when entered.

|source=alpha, foo, lima	|word=foo	foo	Y
|source=alpha, foo, lima	|word=bar		N	full word bar not in the source
|source=alpha, foo, lima	|word=foobar		N	word foobar not in the source as full word

|word= can be a list of words. All will be checked with the AND-requirement (each word must be present).

|andwords= accepts a list of words that all will be checked with the AND-requirement (each word must be present).

Alway, both |word= and |andwords= are combined into one single AND-wordlist.

|orwords=, |orw=

Accepts a list of words that all will be checked by the OR-requirement ("at least one of the words must be present).

|andwords= |orwords=

checks both lists for their own check: "ANd-words" must all be present, "OR-words" must have at least one present.

Result: True if both check results are True, otherwise False.

Blank list(s)

Empty input string(s) will conclude negative:

|source, andwords, orwords=<blank>
|source=<blank>	|word=beta		N
|source=alpha, beta, gamma	|word=<blank>		N

As of Mar 2023, not supported.

|casesensitive=true, |case=true Case-sensitive (A=/=a) DEFAULT

|casesensitive=false, |case=false Not case-sensitive (A=a)

|out-true=out-true, a hit |out-false=out-falset found
|source=alpha, foo, lima	|word=foo	foo	Y
|source=alpha, foo, lima	|word=foobar		N

|booleans=

|booleans=true will convert all boolean words into "True/False".

per module:Yesno (Yes, true, yes, 1 = true) (todo: document value 2?, nil, blanketc. Irrespective of case?)

other words not changed ("horse" remains horse, not T/F).

Note: per logic definition, the word "false" is returned (as being found).

under construction

• The logic itself does not produce errors. There is always a True of False result.

• Pages with Unknown parameters are listed in Category:Pages using str find word with unknown parameters (0).

There are no logical errors foreseen: any flaw in the input will return a False result (for example, no input strings to check were entered).

• |explain=true: when in Preview, display a report on input, output and the logical steps (debug).
• |explain=testcases: When set in ns Template or User on subpage /testcases, the Preview report is static (shown permanently).
