Editing Module:Track gauge/autodocument/doc (section)

==Parser limits (expensive functions)==
Module:Track gauge/autodocument uses ''expensive function'' calls (especially the <code>documentGauge</code> listing). The wiki parser only allows 500 such calls in one page. As of July 2014, this number is almost reached in (~475 in [[Template:Track gauge/doc/input options]]). When, after adding new entries to /data or /extra, the number is reached, a "Script error" will show.

Best practice is to prevent this error: adding content category name to the /data, even if they have default name pattern or do not exist:
<syntaxhighlight lang="Lua">
 ["contentcat"] = "5 ft 3 in gauge railways",
 -- or
 ["contentcat"] = "",
</syntaxhighlight>
This way, these category pages are not checked for existence.
