Update: I have now moved to using a self-made Python program that compiles my markdown article documents into the website you see. I’m keeping this article as a journal of my then experience.

I recently got around to resurrecting my blog up after around five years of death. As part of that, I chose to migrate my blog to Hugo, from the current Pelican builder. The first post after resurrection will be about the migration.

If you’re wondering why the long break, well, I could blame it on life and work, but it was just me being lazy. Hopefully, that won’t happen again.

Why Hugo¶

When I decided to start writing again, I couldn’t remember who I was building the site. That’s probably entirely my fault for not documenting it for myself, but I ended up being almost new to Pelican. So, instead of directly going to Pelican’s homepage, I checked out StaticGen to see the current landscape of static site generators. The most popular (measure by GitHub stars) is obvious, Jekyll. Then came Hugo, a name I didn’t recognize. Other than Pelican, all the ones in the top-ten are built on Ruby or JavaScript (node.js). I wasn’t keen on either. Hugo was in a unique position since it is written in a compiled language, so multiplatform binaries are relatively easy to come by.

I read the documentation on a weekend and I was impressed. Hugo it is. The thing that struck me most in Hugo is that it does it’s primary thing only. Generating HTML files from Markdown files. It doesn’t force a blog-like website or a documentation-like website. That’s up to you. Hugo is like a bridge between your markdown files and the output HTML files. The structure of the output is a mirror image of your source files and the config.toml file (or config.yaml).

Migration¶

A new site¶

Issued the command hugo new site sharats.me.

Configuration¶

Hugo’s default configuration is of the TOML format. I read the README and wasn’t convinced. Thankfully, Hugo supports configuration in YAML.

So, this is what I came up with in my config.yaml file.

baseURL: http://sharats.me/
languageCode: en-us
title: "The Sharat's"

The current config.yaml is much longer and can be viewed on the github repo of this site.

Change metadata format¶

The article metadata in my Pelican site looks like the following:

Title: Serializing python-requests' Session objects for fun and profit
Date: 18.2.2012
Tags: python, python-requests, python-pickle
Reddit: true

There’s a lot of things in this that I wouldn’t do if I wrote that article today, but meh.

Hugo calls these frontmatter and I needed it to look like the following to make it happy.

---
title: Serializing python-requests' Session objects for fun and profit
date: 2012-02-18
tags: 'python', 'python-requests', 'python-pickle'
reddit: true
---

The following awk script did the trick:

BEGIN { FS = ":"; OFS = ":"; print "---" }

!c && /^$/ { print "---\n"; c = 1 }

c { print; next }

!c {
    $1 = tolower($1)

    if ($1 == "date") {
        $2 = gensub(/ ([^.]+)\.([^.]+).([^.]+)/, " \\3-\\2-\\1", 1, $2)
        $2 = gensub(/-([0-9])-/, "-0\\1-", 1, $2)
    }

    if ($1 == "tags")
        $2 = " [" gensub(/[-a-z]+/, "'\\0'", "g", substr($2, 2)) "]"

    print
}

Change code blocks¶

All my code blocks were of the following format:

    :::python
    import this

But, I needed them like this:

```python
import this
```

So, the following little python script did the trick:

1
2
3
4
5
6
7
8
9
10
11
12
13

#!/usr/bin/env python3

import sys


def process(f):
    cb = False
    empties = 0
    output = []
    for line in f:
        line = line.rstrip('\n')

        if not line:
            empties += 1
            continue

        prefix = ''
        if line.startswith('    '):
            line = line[4:]
            if not cb:
                cb = True
                line = line.replace(':::', '```', 1) if line.startswith(':::') else ('```\n' + line)

        elif cb:
            cb = False
            prefix = '```\n'

        output.append(prefix + '\n' * empties + line)
        empties = 0

    return '\n'.join(output)


for file_name in sys.argv[1:]:
    with open(file_name) as f:
        output = process(f)
    print(output)

Yeah, didn’t have the patience to do it with awk this time.

The Theme¶

I tried the themes over at the Hugo themes page, but just as I thought, none of them were to my liking. I found the nofancy theme to be easy to get started and modify to what I want, so that’s what happened. Hugo’s documentation is very good. I have to say, the documentation is one of the reasons I’m loving Hugo.

Hope to be writing more articles in the coming weeks.
