The Automation Begins
The Automation Begins
Having decided I should make a blog to chronicle my adventures in
Emacs, I started looking into hugo a minimal blogging framework
written in GO. It turns out that
hugo has excellent org integration,
incorporating go-org, which is the same library used by Github.
Approach and Setup
As pre-work, I created the (sub) domain where this blog is hosted with
my web hosting provider's CPANEL tools Then I created a new shell user
with access only to the new site and enabled ssh access for the new
user. Finally, I installed my workstation's public ssh key into the
authorized_keys file for new user account I use to publish the blog.
With the setup completed, I created the initial post and published it by hand, then I had supper and watched The Simpsons with the family for a while. Then I created this post and used it to published itself! 😵
Within Emacs, this means putting my cursor with-in each of the
code-blocks in turn then pressing
C-c C-c (That's
to execute the block the cursor is currently within ("at point").
This works because, in the org file "behind" this blog post, I warp
the code-block with special
org-mode specific mark-up that
identifies the programming language. Just as
go-org uses this
mark-up to select the right syntax highligher when rendering HTML,
org is additionally able to use system functions to invite whatever
interpretor based on the type of code the block contains.
#+BEGIN_SRC perl say "Hello, org-babel!" #+END_SRC
Windows: Fix-up for
ob-sh to use
I will run this first code-block only when I have restarted Emacs since I last published the blog. It sets up advice, which are a convenient way to alter how built-in Emacs functionality works.
I'm using Windows 10, so the first thing needed was a
fix for invoking cmd.exe. This SO solution is actually wrapping
babel processing to use cmdproxy, which can pass us back STDOUT
;;(require 'ob-sh) (defadvice org-babel-sh-evaluate (around set-shell activate) "Add header argument :shcmd that determines the shell to be called." (let* ((org-babel-sh-command (or (cdr (assoc :shcmd params)) org-babel-sh-command))) ad-do-it))
Now we can just use
hugo -D to render the site as static content.
Once the static files are rendered I use pscp to upload them to the web host.
pscp -r d:/projects/bla/corwin.bru.st/public/* email@example.com:/home/dh_aw28jd/corwin-emacs
That's it. I'll likely clean-up the output somewhat later on. That's even more likely to happen if I need to "scrape" it for further automation later on.
UPDATE: Thanks again to sachac for the tip to use :results verbatim!
