:TOC: [[#code]] ({{edit|Module:Str find word}})

Implements template '''{{Module:tl|Str find word/links/doc}}'''.

{{Module rating|pre-alpha}}

This module looks for a word being present in a comma-separated list of words. It then returns a {{code|1=True}} or {{code|1=False}} value. By default, the True-value returned is the found word itself; the False-value is a blank string.

{{Lua|Module:Yesno|Module:TableTools|Module:String}}

This module looks for a word being present in a comma-separated list of words. It then returns a {{code|True}} or {{code|False}} value.

By default, the True-value returned is the found word itself; the False-value is a blank string. Implements {{tl|Str find word}}.

For example, in the source string '{{mono|1=foo, bar}}' the word '{{mono|1=bar}}' appears, but the word '{{mono|1=november}}' does not.

:True: <code><nowiki>{{#invoke:Str find word |main |source=foo, bar |word=bar}}</nowiki></code> <small>({{code|1=True}})</small> &rarr; >{{#invoke:Str find word |main |source=foo, bar |word=bar}}<

:False: <code><nowiki>{{#invoke:Str find word |main |source=alpha, beta, gamma |word=november}}</nowiki></code> <small>({{code|1=False}})</small> &rarr; >{{#invoke:Str find word |main |source=alpha, beta, gamma |word=november}}<

Complete words: the complete word is '{{mono|1=foobar}}' ... example needed ...

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

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

:True: <code><nowiki>{{#invoke:Str find word |main |source=alpha, beta, gamma |andwords=beta, alpha}}</nowiki></code> <small>({{code|1=True}})</small> &rarr; >{{#invoke:Str find word |main |source=alpha, beta, gamma |andwords=beta, alpha}}<

:False: <code><nowiki>{{#invoke:Str find word |main |source=alpha, beta, gamma |andwords=beta, omega}}</nowiki></code> <small>({{code|1=False}})</small> &rarr; >{{#invoke:Str find word |main |source=alpha, beta, gamma |andwords=beta, omega}}<

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

:True: <code><nowiki>{{#invoke:Str find word |main |source=alpha, beta, gamma |orwords=beta, alpha}}</nowiki></code> <small>({{code|1=True}})</small> &rarr; >{{#invoke:Str find word |main |source=alpha, beta, gamma |orwords=beta, alpha}}<

:False: <code><nowiki>{{#invoke:Str find word |main |source=alpha, beta, gamma |orwords=beta, omega}}</nowiki></code> <small>({{code|1=False}})</small> &rarr; >{{#invoke:Str find word |main |source=alpha, beta, gamma |orwords=beta, omega}}<

Complete words: the complete word is '{{mono|1=foobar}}' (example needed)

Whitespace is trimmed,

The module is aimed at template code usage. <small>(The editor does not have to apply Lua patterns like {{code|1=[%a%d]*}})</small>.

===Case, Literal,AND-wordlist checks===

: todo: examplify

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

:Alway, ''both'' {{para|word}} and {{para |andwords}} are combined into one single ''AND''-wordlist.
