Static Local Website with Hugo (file:///)

[JeremyBYU]

Hey everyone,
This question will probably seem a little strange to most people because most people dont deploy websites by distributing a folder of html files. However I sometimes do this at work (with a network file share) instead of having to deal with a server.

What I'm trying to do is create a website with hugo that will build all my html files for a simple website and be able to open the html files with a browser. To accomplish this I set baseurl = path_to_file_share. It correctly links all resources in the html files (css, images, javascripts). I open the index.html homepage file in the file share and it loads correctly. However all the link to other posts are broken and are replaced with <a href="#ZgotmplZ">

A little googling brought me to this page which basically says that Go is considering the html to be unsafe and is escaping it. I'm guessing it is the file protocol in the link that it is considering to be unsafe (e.g. file:///).

I know that there are some ways in the Go templating language to disable this functionality (see link). Is there any way we can put a flag in hugo (maybe the config.toml) that will inactivate this html escaping feature.

Thanks for your help

Jeremy

This is an interesting question, but there is an alternative solution. If it were possible to generate all the content using only relative URLs, then it would not matter whether you had a file: scheme or a http: scheme, or even https:.

I tried setting baseurl to "", but this doesn't help you (not at the moment, at least). It sets all the intra-content URLs to start with /, which is OK on a webserver, but rubbish for your use-case. I had hoped that not a single intra-content URL would start with /; that is the acceptance criterion for a portable bundle of content.

I would wholeheartedly support a change to Hugo that generates content with nothing but relative URLs. It should be quite easy to achieve in principle - Hugo knows where everything is. This would be a more general solution to your use-case than merely making file: scheme play nicely.

I've discovered that setting baseurl to "" creates a website with some broken menu links :-(

Hugo cannot deal with this use-case at present, as far as I can tell.

[JeremyBYU]

Yeah I had noticed that as well. It would be great if we could get the relative references working with setting the basurl to "".

I created a VBS script that will automatically make all links created by hugo relative. This works for anchor tags to other posts as well as links to static files (css, js, img). Place the file in the parent directory of the 'public' directory.
Plan to convert it to python on some later date.
Known issues:

• configured website url cant be blank
• the configured website url has to have a trailing backslash /

'relative-reference.vbs
'specifiy the website in config.toml as a command parameter when calling this vbs script.  Make sure there is ending / on website
Const ForReading = 1, ForWriting = 2, ForAppending = 8

pub_dir = "public"
levelPaths = Array("","../","../../","../../../") '4 level for relative reference'

    badPath = "http://localhost:1318/"

This is a noble effort, but...

It would be good to fix the Hugo source code and submit a patch, instead of trying to fix links after they've been created.

Hi @JeremyBYU and @rickb777,

It turns out this issue is very similar to #347 where the user wanted to use irc:// links that got turned into #ZgotmplZ. This was fixed by the addition of the safeUrl template function in commit 724cc0d on 19 Jan 2015, now in v0.13-DEV. This new feature is documented around http://gohugo.io/templates/functions/#toc_12 (scroll down a bit to see it).

So, @JeremyBYU, with Hugo v0.13-DEV, you may now use a baseurl = "file:///path/to/your/website/" with uglyurls = true and have the links work by modifying your templates to use, for example, <a href="{{ .Permalink | safeUrl }}> rather than <a href="{{ .Permalink }}">.

Please let us know how it works out for you!

[rickb777]

This safeUrl solution seems like an ugly hack.

Why is it not possible to construct path-relative URLs so that safeUrl is not necessary?

[anthonyfok]

Hi @rickb777,

I think having a way to construct path-relative URLs is a worthy goal for v0.14 or v0.15.
I took a brief look at it some weeks ago, and thought we could implement something very similar to http://golang.org/pkg/path/filepath/#Rel, but for URL rather than file names. But I was soon busy and haven't had time to follow up yet. (I am still a Go learner.)

I agree that using safeUrl was an ugly hack; I was merely responding to the <a href="#ZgotmplZ"> problem that @JeremyBYU reported in the original post. Though an ugly hack, it works™ for those who need it until proper relative URLs support is available in Hugo.

But yes, not only do we welcome comments and suggestions, we welcome Pull Requests even more! So, if you have time, we would love to receive a PR from you! 😉

This question will probably seem a little strange to most people because most people dont deploy websites by distributing a folder of html files. However I sometimes do this at work (with a network file share) instead of having to deal with a server.

This is not that uncommon actually. Another use case is letting users download a html site (e.g. docs for a software project) as a bundle to use offline.

This issue was closed, but the behavior is still not supported (nor documented as far as I can tell). Using something like:

baseURL = "file:///path/to/networkfolder/doc/public/"

will not result in a working site whether RelativeURLs is set to true or false. If true, themes go missing completely, hugo server doesn't work (it changes localhost:1313 to localhost:1313/path/...), etc.

Can this issue be reopened, or closed as wontfix?

[rgommers]

Update: after a couple of hours of digging I found the answer: relativeURLs = "true" only works in combination with uglyURLs = "true". See #4642 (comment) for more details.

So no need to reopen this. I will see if I can find time for a PR to improve the Hugo docs - searching for terms like "portable", "offline", "deploying to a shared drive", etc. should lead users to a description of this behavior.

[inwardmovement]

I tried:

1. Do not set baseURL
2. Set relativeURLs = "true"
3. Set uglyURLs = "true"

But it doesn't work for me.

Couldn't we simply create a hugo parameter to build "for local" while taking care of all these "not for local" problems, while not depending on baseURL, relativeURLs, uglyURLs, canonifyURLs (and so on)? hugo --local for example.
