From da08fad5f3a79ffd577dbc0514cc3e366f883f9b Mon Sep 17 00:00:00 2001 From: Rick Cogley Date: Wed, 29 Apr 2015 07:41:08 +0900 Subject: [PATCH] Add index reference to go template primer doc page Related to @bjornerik 's answer in this discussion: http://discuss.gohugo.io/t/inserting-data-from-data-file-into-content-file-newbie-question/1002/3 ... I figured I'd make myself useful and add the reference to the index function, on the go template primer page. Also, I moved the reference links to the bottom. A general comment: as good as these docs are, the primer at this point makes some assumptions about audience knowledge, so some might find it lacking. Once I understand better, I might make some more clarifying edits. --- docs/content/templates/go-templates.md | 12 ++++++++---- 1 file changed, 8 insertions(+), 4 deletions(-) diff --git a/docs/content/templates/go-templates.md b/docs/content/templates/go-templates.md index adb1ae3c9..86555fd8f 100644 --- a/docs/content/templates/go-templates.md +++ b/docs/content/templates/go-templates.md @@ -144,6 +144,10 @@ range. {{ $element }} {{ end }} +The `index` function is a [Go][] built-in, and you can read about it [here][gostdlibpkgtexttemplate]. `index`: + +> ...returns the result of indexing its first argument by the following arguments.
