Extract date and permalink from filename #285

xaprb · 2014-05-11T01:15:22Z

One of the Jekyll features I enjoy is extracting the date and slug/permalink from the filename so I don't need to specify them in the front matter. It would be nice if Hugo would support this as well.

The Go re2 library supports named capture groups in regular expressions. So one option for this feature would be to configure a regular expression in the config.yaml that, if it yields named matches, could populate the content date and/or link, e.g. if you like to prefix your file names with a date like '20140531-something.md' in would match:

filename-re2: "^(?P<year>\d{4})(?P<month>\d{2})(?P<day>\d{2})"

http://code.google.com/p/re2/wiki/Syntax *

(?P<name>re)    named & numbered capturing group

* The 'P' stands for either 'Principled' or 'Perverse' YMMV :-)

Here's a workaround until the enhancement made for people on linux/macs, or if you're smart and figure out how to do it on windows.

POST_SRC := $(subst ./,,$(shell find ./src/post/ -regextype posix-extended -regex '.*[0-9]{4}-[0-9]{2}-[0-9]{2}-.*\.md'))
POST_DEST := content/post/

default: all

define POSTS_PARSE
_target := $(POST_DEST)$(shell echo $1 | grep -Po '\w+\.md')
POSTS := $$(POSTS) $$(_target)
$$(_target): $1
    date=$$$$(echo '$$<' | grep -Po '\d{4}-\d{2}-\d{2}') && \
        sed "1 adate: $$$$date" $$< > $$@;
endef

$(foreach x,$(POST_SRC),$(eval $(call POSTS_PARSE,$x)))

posts: $(POSTS)

init:
    mkdir -p content/post/

all: posts

clean:
    rm -rf content/post/*

.PHONY: all posts init clean

put your original files in ./src/post and it will export to ./content/post. Just type make for one time use and watch make when actively editing files.

It's easier to keep the files organized too.

Note/Update: This issue is marked as stale, and I may have said something earlier about "opening a thread on the discussion forum". Please don't.

If this is a bug and you can still reproduce this error on the latest release or the master branch, please reply with all of the information you have about it in order to keep the issue open.

If this is a feature request, and you feel that it is still relevant and valuable, please tell us why.

@bep

Easier to keep the files organized
No need to charge the Front-Matter with the info (same goes for the language for example)

borisschapira · 2017-03-01T09:59:11Z

And I'll add: easier to migrate from Jekyll :)

xaprb · 2017-03-01T15:58:53Z

I agree, it's a feature request and valuable for the reasons Boris mentioned.

Parses filenames for a given date format and parses it into the date variable. Applied using the useFilenameDateAsFallback configuration option which defaults to false for backwards compatibility. Useful for content migration (e.g. from Jekyll et. al.) where date values are provided in filenames and not in frontmatter. Additional config values filenameDateFallbackPattern and filenameDateFallbackFormat allow custom date formats. Partially addresses functionality discussed in gohugoio#285 fix tests

This issue has been automatically marked as stale because it has not had recent activity. The resources of the Hugo team are limited, and so we are asking for your help.

Please, don't give up on this.

This commit adds `enableFilenameDateAsFallback` 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. Fixes gohugoio#285 Closes gohugoio#3310
