I like to display “published date” and “last modified date” info for my posts. Date info comes from the date parameter and last modified info comes from the lastmod parameter, both defined in the front-matter.

date: "2020-08-22"
lastmod: "2020-08-22"

Get Date-Info Partial

To get date-info I’ve created a simple partial template. Which basically, checks if the “lastmod” and publish dates are the same then renders the dates. To compare two dates, we should format them using the same date format. “02.01.2006” is equal to “dd.mm.yyyy” in the Go language.

{{ $date := .Date.Format "02.01.2006" }}
{{ $lastmod := .Lastmod.Format "02.01.2006" }}

<span class="date-info italic">published on {{ $date }}</span>
{{ if ne $lastmod $date }}
    <span class="date-info italic"> <br> edited on {{ .Lastmod.Format "02.01.2006" }}</span>
{{ end }}

Get LastMod Using Git

There is a very cool feature in Hugo, that can get the “lastmod” info from git. You need to enable it in the config file: config.toml.

enableGitInfo = true

Still, if lastmod parameter exists in front-matter, Hugo will use the date from the from-matter, not from git. So, you can freely enable the feature and use the parameter whenever you want to manually enter another date.

I realized that Hugo still using the lastmod info that is coming from git even if we set the lastmod parameter in the front-matter. The good thing is we can change this behavior by configuring front matter.

[frontmatter]
date = ["date", "publishDate", "lastmod"]
lastmod = ["lastmod", ":git", "date", "publishDate"]
publishDate = ["publishDate", "date"]
expiryDate = ["expiryDate"]

By default, ":git" comes before "lastmod". To override it, we need to add these lines to the config file.

Convert Dates Into Your Language in Hugo

We talked about rendering dates and the last modification date in the last post. Now, we’ll look into how can we convert month names into another language? I’ve had a similar experience last year with jekyll. The idea is the same, we need to map each month to their version of the …

In Hugo and generally other static website generators, we are using data files to store data. These files can be in YAML, TOML, or JSON formats. You can always read more about data template in the original documentation. Yet, I want to give some examples from my blog. First of all, converting dates …

The question is clear. We need to pass variables or arguments in Hugo’s partials. We usually use only the dot when calling partials. {{ partial "foo.html" . }}. The dot means the current page’s context. All it’s variables like .Title, .Permalink, .Content and all others …

Previously, I’ve published a blog post about deploying static content on heroku with basic authentication. You can find the link here. In that post, we hosted the source code on GitLab and configured a CI/CD pipeline to render the static content a.k.a html files and push these files to Heroku. …

Each git commit has a field called Author which consists ‘user.name’ and ‘user.email’. We usually set these variables once, after installing git, with git config --global so that each repo gets the variables from the global definition. We can also set them locally for a …

I’ve been using WSL-2 on Windows for over a year. It’s very useful because some Python packages are just a headache to install on Windows. Also, docker. It’s just better on Linux. Yet, WSL-2 can also be problematic. I remember trying a dual-boot setup when things just went way too …
