Module:DecodeEncode/doc

Implements Lua functions mw.text.decode, mw.text.encode in a module.

{{#invoke:decode|s=Source text}} → Source text

See List of XML and HTML character entity references.

Decodes Named Entities from entity name into a regular (unicode) character:

© → ©

> → >

All welldefined named entities are decoded (HTML Named character references, formally: as defined in the PHP table).

A regular, rendered sentence:

"At 100 °F, & with a "burning" sun above, we walked"

In code:

"At 100 °F, & with a "burning" sun above, we walked"-- in code

Processing:

{{#invoke:decodeEncode|decode|s=At 100 °F, & with a "burning" sun above, we walked}} →

At 100 °F, & with a "burning" sun above, we walked -- In code: no named entities

By setting |subset_only=true, only these five entity names are decoded: '&lt;', '&gt;', '&amp;', '&quot;', '&nbsp;' (that is, into '<', '>', '&', '"', ' ').

Note: There is a difference with the relevant Lua parameter. (This only concerns your task if you also work directly with the Lua mw.text.decode function). Lua documentation defines parameter |decodeNamedEntities=, having this effect: when omitted or false, only the reduced set of entities is recognized and decoded. This use of 'false' is inverted in using |subset_only=: |decodeNamedEntities=false = |subset_only=true.

Also, this module ignores the "omitted" logic: |subset_only= should be set explicitly to 'true' to be effective.

Function encode encodes some entity-named characters into that name (for example: & → &).

Regular sentence:

"At >100 °F, & with a "burning" sun above, we walked. ©"

In code:

"At >100 °F, & with a "burning" sun above, we walked. ©"

Encode:

{{#invoke:decodeEncode|encode|s=At >100 °F, & with a "burning" sun above, we walked. ©|charset=&<>{{!}}°"'&©}}

→

At >100 °F, & with a "burning" sun above, we walked. ©

Per Lua documentation, only a small set of characters is processed. The charset can be set (|charset=). Format

Use escape character is '\' (backslash; not "%" then). Example: |charset=<>" \'& (the default), |charset=<>\|\°\"\'\&©; characters not in the default will be replaced by their decimal entity: © → © (hexadecimal number, not decimal nor named &copy;)

As of Dec 2020^[update] , there are no tempates implementing this module.
