Make RVM's Ruby Available to Emacs Shell Commands

No matter if you use exec-path-from-shell or not, Emacs will not be able to know your RVM-managed Ruby information. This drove me crazy. Most Emacs shell commands are invoked in an “inferior” mode, aka a “dumb” shell. This includes M-!, M-x shell, and also the projectile compile commands. That’s when some of your user login scripts will not automatically load, like the entirety of rvm, the Ruby Version Manager.

Add HTML Entity Picker to Emacs

Emacs comes with a lot of stuff out of the box, but I was missing TextMates “Insert Entity” action that lets me search through HTML entities by name and then insert " or ™ for me. I can never remember the names of typographic quotation marks in German, for example.

Delete the Next Word or the Current Selection in Emacs with the Same Shortcut

When you delete a character or the current selection, you usually hit C-d (Control + d) in Emacs. I got into the habit of revising drafts by deleting whole words, and the M-d (Meta + d) key combination is super useful for that. It also works into the other direction with backspace. It’s essentially the same effect of +backspace everywhere else in macOS.

Indie Support Weeks: beorg

Teaser image

This is week two of the COVID-19 lockdown that led to #IndieSupportWeeks to help independent developers get a shoutout and maybe find a couple extra customers.

For today’s installment, I picked beorg.

beorg is a bit weird. It’s basically a task manager and calendar, but based upon plain text files that I sync via Dropbox. It’s not a particularly user-friendly application, and its UI didn’t win any prizes, unlike e.g. Things or OmniFocus (I’m often confused by the app icons and lack of labels, but also glad because my iPhone 5S screen is so smol). So why did I pick this app, then?

Urist likes beorg for its visual representation of plain text outlines

beorg is a mobile companion for my Emacs org mode files. It’s capable of handling org mode outlines, and parts of these outlines can be tasks or TODOs, and you can group them in projects, and then display an overview or “Agenda” – and things get out of hand quickly from there. Emacs is ridiculously customizable, and org mode is no different. beorg makes these information available on mobile.

So since over the years I moved from OmniFocus 1 to Things to OmniFocus 2 to Emacs, I got used to viewing tasks on my mobile phone and iPad; and I really much like the capability to capture information on the go. A piece of paper will do most of the time; but having a web clipping synced to my computer directly is nice.

You can even write Scheme scripts inside beorg! I haven’t touched that topic at all. The REPL (yes, it has a REPL!) provides a sandbox for experimentation, and by convention beorg will load and run init.org file from your list of files right after bootstrapping. You can even customize the app’s UI with this. Writing org files that auto-execute during launch to customize the behavior of the editor is a long-running theme, see this random example (source).

Regarding the business model: most stuff is free, and the free version will get you really, really far. You currently can buy access to additional features:

  • “Properties” will let you add custom key/value pairs to any item; it’s mostly a UI affordance for the plain text underpinnings
  • “Encryption” to, well, encrypt your items or files
  • “Task Timers” to track how long you work on a task (ahem, I suggest an automated service like Timing for that)
  • “Templates” are pretty self-explanatory, and org mode capture templates can get out of hand and cover JIRA ticketing, for example (did I mention you can configure org mode to sync with JIRA?)
  • “Export Themes” are CSS styles to generate HTML from your outlines because, well, org mode is supposed to be a structured markup language for HTML and LaTeX export and such thing
  • “UI Themes” for Solarized and additional dark modes in the app
  • “Saved Searches” to more quickly access the results of complex searches
  • “Box Sync” to … sync to Box.net (beats me why this of all things is an add-on)

The developer provides release notes for updates in the app, which I absolutely adore for this kind of “make it your own” pro user application, to make sure I keep up-to-date with the good stuff. The tip jar that goes along with it is probably the main source of his income – at least as much as I’m concerned. The updates are really good and much appreciated.

Native macOS Notifications for Emacs Org Tasks and Appointments

Emacs is a text editor, kind of. But I use its Org mode for “keeping notes, maintaining TODO lists, planning projects, and authoring documents with a fast and effective plain-text system” – its Agenda became my daily productivity hub. It’s a calendar view of all things scheduled for the day, plus some other info interspersed: thanks to the plain text nature of the whole interface, it’s simple (albeit not easy) to re-style everything you see there. Add sub-headings, spacing, links, text, what have you.

Emacs Settings for PHP Development

Teaser image

The project that I’ve been working on over the weekend, I worked on in emacs. This is part of my re-learning the basics of text editing and programming in emacs to slowly move away from TextMate when it comes to scripts. I want to move away from TextMate because I eventually want to transition to be productive on a Linux machine – that means, to create stuff in an otherwise foreign operating system. Emacs is portable, so that’s a good start.

Fold Current Level-1 Heading in Emacs Org-Mode Outlines

There’s no standard shortcut to fold the current subtree of an org-mode outline. When I work in org-mode outlines, I usually am 3 or more levels deep into a so-called “subtree” and want to get back to the root item, fold it to hide the details, then drill down into another item. I use that when I am working on an app and want to have a look at a planned milestone nested deep down at a different point in the outline.

Emacs for Remote SSH Python Development

Teaser image

I am using Emacs for over a year now to manage my tasks. I like how I can mix tasks with long form notes in a single outline. It’s good. We had to play with vi and emacs for a while at University. I’m very happy I got used to the very basics of both editors because I ended up using vi a lot when SSH-ing into remote machines, and now Emacs for everything else.

Add Blog Post Text Template Expansion to Emacs with Org Babel

In my quest of total immersion into Emacs, I am trying to write blog posts in Emacs instead of TextMate. That means my TextMate macros are gone for good, including insertion of YAML header information. On this very blog and on Zettelkasten.de, I used to type cthead and zkhead respectively, then expanded the YAML header with tab. TextMate’s great template feature even allows you to specify multiple points inside the templates to jump to by tabbing forward. Emacs works a bit differently, so I adapted the templates to request information up front instead and fill in the values.

Indent Code and Lists by 4 Spaces in Emacs Markdown Mode

I noticed that my Emacs didn’t maintain the current line’s indentation when editing code blocks in Markdown (markdown-mode). I indent the first line with 4 spaces like any sane person would. When I hit enter to continue in the next line, thanks to the markdown-mode defaults, I am presented with a new line that’s properly indented visually. Only when committing to git did I notice that Emacs inserted tabs instead of spaces. Gasp!

Global TODO Capture Hotkey for Emacs Org Mode on macOS

I am using GNU Emacs for a while now to do all kinds of stuff. I’m thinking about migrating away from OmniFocus as my task manager and use Org mode instead. What I like so far is the free-form list nature of Org files. I can have an outline of notes and sprinkle TODO items inside them. This way I can take notes on puzzling problems I’m working on and mark things I need to do later. This is super useful to remind myself what to clean up before a commit, for example write or amend tests or remove debug code somewhere. I like it. I got used to a lot of shortcuts already, so most of the pain of daily use is gone.
