From ee273fd80f8061b88445b7432cc72c8633cc428c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bj=C3=B8rn=20Erik=20Pedersen?= Date: Wed, 21 Feb 2018 11:09:08 +0100 Subject: [PATCH] hugolib: Extract date and slug from filename This commit adds a new config option which, when enabled and no date is set in front matter, will make Hugo try to parse the date from the content filename. Also, the filenames in these cases will make for very poor permalinks, so we will also use the remaining part as the page `slug` if that value is not set in front matter. This should make it easier to move content from Jekyll to Hugo. To enable, put this in your `config.toml`: ```toml [frontmatter] defaultDate = ["filename"] ``` Fixes #285 Closes #3310 Closes #3762 Closes #4340 --- hugolib/page.go | 129 +++---- hugolib/page_paths.go | 2 +- hugolib/page_test.go | 109 ++++-- hugolib/pagemeta/page_frontmatter.go | 405 ++++++++++++++++++++++ hugolib/pagemeta/page_frontmatter_test.go | 250 +++++++++++++ hugolib/pagemeta/pagemeta.go | 32 ++ hugolib/site.go | 11 + 7 files changed, 823 insertions(+), 115 deletions(-) create mode 100644 hugolib/pagemeta/page_frontmatter.go create mode 100644 hugolib/pagemeta/page_frontmatter_test.go create mode 100644 hugolib/pagemeta/pagemeta.go diff --git a/hugolib/page.go b/hugolib/page.go index fd6278bb443..170c15dddf6 100644 --- a/hugolib/page.go +++ b/hugolib/page.go @@ -1,4 +1,4 @@ -// Copyright 2016 The Hugo Authors.
