5- Progress?

My friend has an API that if called will return a picture of an anime girl, and will return a new one every 24 hours (I think that’s how it works, truthfully I’ve never curl’d it). Thinking about that combined with a rant Luke Smith once made about fixing pull requests on his GitHub, I wish there was an API I could call to give me a random picture of a Pink Wojack every 24 hours. It would help me get across my current… mood? Is mood the right word?

I’ve made progress - I am even at a point where I could have this finished tonight. Needless to say, the route we were taking has changed.

Previous plan

For more details on this, I would recommend reading the post before this but for a summary… The plan was to use Hugo OutputFormats to generate two outputs from the same markdown file, one regular and one plaintext. I would then use a Python script to strip the PGP artefacts from the content.

This made a series of stupid stupid assumptions, all of which I have had to make some cringe/genius solutions for

You can create separate text/html outputs, and apply a different theme to them
That I can deploy a Python script to filter out the . Content data during the build process from within the single.html template.

I will detail how I have-fixed/am-going-to-fix these in the sections below. I would like to mention, however, that as much as I want to lobotomise myself right now as a relaxation exercise, this experience has been fun and informative.

Applying separate themes to `text/html` outputs

Is this possible? No. I’m sure with enough fiddling it is possible, however, I ideally wanted to do this with minimal edits to the theme I am using. I have been avoiding learning HTML and CSS for 25 years, and I want to have a long happy life without ever breaking this streak.

What I did instead of using separate themes is read the documentation (and reach out for help on one or two Discord servers). So as I mentioned before, Hugo can support separate OutputFormats. By default, it uses text/html for pages, but within the text category there is also text/plain. Now I made the mistake originally of assuming declaring isPlainText = false in my hugo.toml file would have the same effect - I was wrong (I don’t know what that flag does). Given this, I edited my hugo.toml file so it now looks like this

[outputFormats]
    [outputFormats.standardFormat]
        name = "standard-format"
        baseName = "index"
        isPlainText = false
        mediaType = "text/html"
        path = ""
        permalinkable = true
        weight = 1

    [outputFormats.sigFormat]
        name = "sig-format"
        baseName = "index"
        isPlainText = true
        mediaType = "text/plain"
        path = "sigs"
        permalinkable = true
        weight = 2

What also needs to be done is you need to make a template for this .txt file. So I made a file called layouts/_default/single.sig-format.txt which contained the following

{{ .Plain }}

With these changes theoretically, these two pages should be made - The top one being regular, and the second being a plaintext version with the signature.

Of course, it wasn’t that simple. You see .Plain is meant to return the rendered content of the given page, removing all HTML tags… This is not what I wanted, and even if it was it still doesn’t remove all the html artefacts i.e. Microsoft’s will appear rather than Microsoft's. Encountering this problem I did some googling and encountered this post which detailed how she was having a similar issue, with a link to GH and how she solved it. So I used her code, and single.sig-format-txt became the following

{{- $rawContent := .RawContent -}}
{{- range .Site.Data.article_txt_replace.args -}}
  {{- if not .skip -}}
    {{- $rawContent = $rawContent | replaceRE .pattern .replacement -}}
  {{- end -}}
{{- end -}}
{{ $rawContent }}

Following this I signed a post using gpg --clearsign, and used hugo server to generate it. I then curl’d down the content, and used gpg --verify to confirm it works - No errors, so looks like for now are good. I should probably initiate an automated test to confirm the sig checks out, but that will be a job for once this is done.

`.Content` filter

So this one is a tad annoying, but not as much as it could have been. The original plan was to use something like this to filter out the Content data during the build process, by editing the theme. See if you can spot the issue.

{{ $content := .Content }}
{{ $filteredContent := printf "%s" $content | exec "python filter.py" }}
<div class = "content"> {{ $filteredContent | safeHTML }} </div>

If you didn’t know and don’t worry if you didn’t, it’s the use of exec. Hugo doesn’t let you do this, and I was an idiot for assuming that I would.

What is even more potentially idiotic is I write the Python script to strip the PGP first. I say this is idiotic because if it turned out I wasted time writing that, I could have risked rage quitting this whole endeavour (luckily I think I have found a workaround). Regardless, for the sake of people not thinking I am a total idiot with Python, based on my potential code last post, here is the new script that works

import sys

def main():
    raw_data = RawData(file=True).string
    gpg_client = Gpg_client()
    message = gpg_client.extract_content(raw_data)

    return message

class Gpg_client:

    def extract_content(self, signed_message:str):
        ## Strip out begining
        content_start_index = signed_message.find('\n\n')
        if content_start_index != -1:
            content = signed_message[content_start_index + 2:]

        ## Strip out signature at the end
        sig_start_index = content.rfind("
