Module:DecodeEncode/doc

Template:Module rating 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.

Decode (© → ©)

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 , we ⁄walked⁄."

In code:

"At 100 °F, & with a "burning" sun above, we ⁄walked⁄." -- wikitext

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: straight characters, no named entities.

Renders, again:

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

Decode a reduced set only

By setting Template:Para, 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 Template:Para, 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 Template:Para: Template:Para = Template:Para.

Also, this module ignores the "omitted" logic: Template:Para should be set explicitly to 'true' to be effective.

Encode (© → &copy;)

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. ©

Renders as:

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

character set to encode

Per Lua documentation, only a small set of characters is processed. The characterset can be set (expanded) by using Template:Para.

Example: Template:Para (the default), Template:Para; characters not in the default will be replaced by their decimal entity: © → © (hexadecimal number, not decimal nor named &copy;)

Template:As of, there are no tempates implementing this module.
