I don’t know much about Go, but I saw so many tweets it’s a great language, performance wise especially. Hugo is a static blog/site generator written by Go. I feel great with Hugo because of the simplicity. The program is provided as a single binary file. Other tools require a lot of small settings, installing language, setting envrionment, handling a package manager, for example. It still requires some config file, but no worries, it’s not that big.
This blog serves on Github Pages. If the blog is using Jekyll, Github is the best place to serve the blog because Github provides built-in Jekyll serving as a first citizen. Otherwise, Hugo is in the wild. After writing something new, it need to render new static pages, then push that files on the repository. When you publish every single time by hand, it is a huge chore and I will never use it again. In that case, TravisCI is the solution. It’s available to use it for the rendering after new post pushed.
Mac users can install Hugo via Homebrew easily.
$ brew update && brew install hugo
The installation is very easy for the most of the platforms. If you are not a Mac user, check the Releases page.
The excerpt of Quickstart document is the below:
$ hugo new site haruair $ hugo new post/hello-world.md $ hugo
You can find the result under the
public directory after
Hugo provides simple webserver for the local.
--watch flag is useful for the
editing that the page will refresh every save moment. Also, it’s avilable to
build within drafts using
$ hugo server --watch --buildDrafts $ hugo server -w -D # same as the above
Initialize a git repository
The strength of static blog is that it don’t need any program specific environment. There are several options, Amazon S3, Dropbox, etc. Even it’s possible to use some abandoned old geocity-ish service. Github provides Github Pages for this case and it’s free to use.
Create a Github account if you don’t have one. Then,
Create a repository using
<username>.github.io as a name.
Go to the your hugo directory, and make it as a git repository, then push it to Github.
$ git init $ git checkout -b code $ echo '/public/' >> .gitignore $ git add . $ git commit -m "Initial my blog" $ git remote add origin haruair.github.io
code branch for the original source, the static file in
directory will goes into the
master branch as an orphan branch.
$ hugo $ export HUGO_TEMP_DIR=$(mktemp -d) $ cp public/* $HUGO_TEMP_DIR $ git checkout --orphan master
Add a deploy script
If you build the site manually, it’s just boring. Travis CI allows us to add a deploy script after build the static pages. I found the script from rcoedo.com, I just put my script below, just in case.
$ mkdir scripts && cd scripts $ wget https://raw.githubusercontent.com/haruair/haruair.github.io/code/scripts/deploy.sh $ git add deploy.sh && git commit -m "Add deploy script"
I do love pre-config file. The config is here. This config need to update as own details.
The important part is
before_install part. Delete this section from the yml
file, then add it back with your ssh key. Yes, your ssh key!
Before add the key into the repository, it will encrypt using
be aware, do not add the original private key into the repository.
Travis CI provides a CIL tool for the work. Let’s install this tool, first. It’s using Ruby, therefore, you can install it via gem.
$ gem install travis --no-rdoc -no-ri
If you don’t have Ruby on your machine, please check the document from Travis CI.
Create a new ssh key and encrypt it
It’s available to use an existing key, however, creating new one for Travis CI
is good for the security. Make sure that
ssh-keygen can be overriding a
id_rsa, be careful before type the enter.
I created the ssh key named
travis_key. The result of this commend is the
pair of the key:
travis_key.pub. The first one is a private
key, the other file is a public one.
Now, we can add
travis_key into Travis using the commend below:
$ travis encrypt-file travis_key
If you are not logged in Travis before, you may need to run
After then, travis add encrypt file and set the environment variable for the encrypt file. Make sure all files are included in git repository and push it to Github. Also, do not commit the “unencrypt key” into your repository.
Register the new key in Github
In Github setting page, go to the ssh section and add
travis_key.pub for the
deploy. More informations here.
Enable a repository on Travis CI
Go to the profile page of Travis CI, Find out
the repository, then turn on the switch. It will do the build and will push back
All done. Just add new post using Hugo, push to Github, Travis will handle all build problem.
The quickest and the easiest way is here. Clone my repository haruair.github.io, clean up all details and configurations, and use it. Please make sure that the credential is correct.
It’s a quite long description than I thought. Tools support the writing, however, the key of writing is based on all own ideas. Keep sharpening your idea using awesome writing tool Hugo.
