# Gallery: Mixing Styles

This example uses the glossaries-extra package, which extends the glossaries package and provides better abbreviation handling. You’ll need at least version 1.04 of glossaries-extra.sty (you’ll also need a fairly up-to-date version of glossaries.sty as well).

This example is quite complicated as there are a lot of different styles in use. Each entry is assigned a category. The label may be any label you choose, but take care that it doesn’t contain any special characters. Be careful not to confuse the category key with the parent or type key (see Logical Glossary Divisions (type vs group vs parent)). The parent key allows you to have a hierarchical structure in your glossary and the type key allows you to have multiple glossaries.

A single glossary may contain entries with different categories and entries with the same category can be spread across different glossaries. The categories and their attributes allow fine tuning of the way entries are displayed both in the document text and in the glossary.

Semantic commands, such as \animalfont, are defined for each category. This allows the control sequence name (the command name without the leading backslash) to be used as a value for the (custom) font attribute and (supported) glossnamefont attribute. The \glsxtrregularfont command that encapsulates regular entries is modified to pick up the value of the custom font attribute.

The abbreviation and bacteria categories aren’t considered regular entries. (They use one of the abbreviation styles that sets the regular attribute to false.) This means that they won’t pick up the font attribute. Instead the font change must be handled by the abbreviation style or by redefining \glsxtrabbreviationfont. In this case, the abbreviation style is handling it. The glossdescfont attribute can be set to apply a font change to the description in the glossary.

Another attribute that’s used is glossname, which automates case-changing for the name field when it’s displayed in the glossary (where supported by the glossary style).

The “post-link” hook, which occurs after the link-text produced by commands like \gls is altered for the entries with the unit category:

\newcommand*{\glsxtrpostlinkunit}{%


The entries with the category set to constant also have their post-link hook adjusted so that the description and user1 values are inserted after commands like \gls but only on first use:

\newcommand*{\glsxtrpostlinkconstant}{%
\ifdefempty\glscustomtext
{\glsxtrifwasfirstuse{ (\glsentryuseri{\glslabel},
\glsentrydesc{\glslabel})}{}}%
{}}


This category also adjusts the post-description hook so that the value of the user1 is also automatically inserted after the description in the glossary:

\newcommand*{\glsxtrpostdescconstant}{\space
(\glsentryuseri{\glscurrententrylabel})}


As with Abbreviations With Translations, this example also has abbreviations with translations where again the translation is stored in the user1 field. The short-long-user abbreviation style can be used to automatically insert the translation in the parenthetical material on first use of commands like \gls. The post-description hook is adjusted to automatically insert the translation after the description in the glossary (for the abbreviations with the category set to foreign):

\newcommand*{\glsxtrpostdescforeign}{\space
(Translation: \glsentryuseri{\glscurrententrylabel})}


There’s one awkward case where the short and long forms end with a full stop (period). This has the category set to foreignenddot so that it can be dealt with separately. If the abbreviation is referenced at the end of the sentence, this can cause a duplicate full stop, so the end of sentence period has to be discarded:

\glssetcategoryattribute{foreignenddot}{discardperiod}{true}


but not on first use (because the user1 text doesn’t end with a period):

\glssetcategoryattribute{foreignenddot}{retainfirstuseperiod}{true}


This foreignenddot category also needs to have the post-description hook set to match the foreign post-description hook:

\newcommand*{\glsxtrpostdescforeignenddot}{\space
(Translation: \glsentryuseri{\glscurrententrylabel})}


The page list is prefixed with “Page: ” or “Pages: ” using:

\GlsXtrEnablePreLocationTag{Page: }{Pages: }
