Yesterday I was working on a problem with an Emacs wizard, and I saw him do a couple things in Emacs that made me squirm. You see, I badger and belittle him at every opportunity for not embracing The One True Editor, but I saw him perform two actions in Emacs that I didn’t know how to do in Vim. And no way was I going to admit that, at least not to him.
Here are the two items:
When he ran a command from a shell with a lot of output, he piped the output directly to Emacs like this:
$ some_command | ecbuffer
I’m on a Mac, so I typically do this:
$ some_command | pbcopy
And then I open a new MacVim window and hit Shift+P to paste (I use the system clipboard in Vim). Inelegant in comparison. So, while his back was turned, I googled and discovered that passing – to vim causes vim to read from stdin, so I can just do this:
$ some_command | mvim -
Works great! I breathed one sigh of relief, but still had a second item to tackle: we were trying to solve a build issue in which a required jar file was not being included in the 1.2GB deployment file (that’s not a typo — we really roll that large). I noticed that when he opened a zip file in Emacs, it churned for awhile (hey — 1.2GB is a lot of data!), and then showed the zip file’s table of contents. Cool! My best thought for how to do that in Vim, using what I’d just discovered, was this:
$ jar tf foo.zip | mvim -
Not bad, but not as cool as what my coworker was doing in Emacs. So, before getting too worked up, I tried opening the zip file in Vim to see what would happen. Immediately, the table of contents for the zip file appeared in Vim. No churning. No wait. And then I could press Enter on one of the file names to view the file contents.
So, my Emacs-loving coworker made me learn two cool things about Vim. I need to work with him more often!
I’ve been working a lot lately with LESS and Bootstrap, and wanted an easier and quicker way to visualize colors and what the various LESS operations do to them. So, I built hc — Hex Colors on the Command Line. It’s written in Objective-C and works on Mac OS X 10.9+.
It’s still in its infancy, of course, but it lets you do things like show, lighten, or darken colors. To show the color red, for example, type:
hc show f00
That will display, in your console, the text:
rgb: 255, 0, 0
hsl: 0°, 100%, 50%
You can pass 3- or 6-character hex codes. You can also change the output format using the -o/–output option. To write the color to an image file, for example, type:
hc show f00 --output file
This will create a 256×256 PNG file in your current directory called ff0000.png that looks like this:
You can also write the textual results to the clipboard using -o clip, or to a user notification (thanks for the idea, Rob!) using -o note. The notification looks like this:
Be sure to read the README for more information. Check it out and give me feedback!
Although I usually edit files with (graphical) MacVim, I occasionally launch terminal vim. When I do, I see this:
github-issues.vim requires Python support, sorry :c
I always smile a bit at my nephew’s use of an extra-frowny mouth, but I also wince a bit to know that I’m letting this issue linger, rather than fix it.
The simplest fix is to use terminal macvim as my system vim, so last Friday I opted for what I expected to be the easy route and typed:
brew uninstall macvim
brew install macvim --override-system-vim
My system churned a bit while I watched the github-issues.vim animated GIFs, and then reported:
if_ruby.c:677: error: 'rb_encoding' undeclared (first use in this function)
Years of raising children has taught me that I can’t expect proper results without diligent monitoring, so I ran the install command again, but this time I watched it like a hawk, and actually expected different results. After the same system churn, of course, I got the same result. Then my stomach began to churn a bit, and I downloaded the MacVim source from GitHub, followed the build instructions, and got the same result.
I’m nursing this work laptop, a 2010 MacBook Pro with Snow Leopard, along until I come due for one of the shiny new retina MacBook Pros with Mavericks. I may not get one until they sport Yosemite, though, and I don’t think they plan to upgrade the OS on this laptop. You never really want to get on IT’s radar anyway, because them looking closer at your work-issued gear tends to go in directions you didn’t anticipate (“Is that the approved wallpaper? Is Homebrew even approved? Are you running a web server on here???”). What this means, though, is that I can’t use any of the latest editors (Sublime Text 3, Atom) because they’re not supported on Snow Leopard. Which means I can run Sublime Text 2 (Vintage mode, of course), but for some reason its display goes wonky on my laptop, and I really didn’t feel like investigating display glitches in a dead-ended editor. Besides, I’ve got my vim set up perfectly with settings and plugins, and anything else is a step backwards.
So, I opened the source code referenced in the error message. Line 677 of if_ruby.c was housed in this block:
673: #ifdef RUBY19_OR_LATER
674: int isnum;
675: long lval;
676: char_u *sval;
677: rb_encoding *enc;
Hmm . . . I remembered that last week I’d installed Ruby 2.1.3 via rvm. Before that, though, I was definitely using at least Ruby 1.9, so I was a bit confused, but really all I wanted to do was get MacVim working and go home. It was Friday evening, after all. So I typed:
rvm use system
This took me to ruby 1.8.7. Then I typed:
brew install macvim --override-system-vim
This time, after the churn, I got a successful completion, and now MacVim runs and vim uses terminal macvim and github-issues.vim no longer gives me the turbo frown.
And if you’re from my IT department and are reading this, I have only the company-issued wallpaper, I’m totally joking about Homebrew, and I don’t know what a web server is. And can I get a shiny new rMBP with Yosemite?
Last week, I was frustrated with Oracle SQL Developer (on Mac OS X) for two reasons:
- When a connection times out (after being left idle too long), the application hangs and I have to Force Quit and restart it.
- Every 90 days, the passwords for our databases change, so an updated connection XML file is put into source control (passwords are encrypted, and we aren’t allowed to know the passwords) and we have to import the new connections. You can’t delete multiple connections at a time from the SQL Developer interface, and importing over an existing connection pops up a Yes/No dialog box asking you if you want to overwrite the existing connection. Since the file contains about 30 connections, this means clicking Yes to the same dialog box 30 times.
I decided to vent, and tweeted this:
I wish more software developers used the software they create on a regular basis, so they’d fix the annoyances. *ahem Oracle SQL Developer*
— Rob Warner (@hoop33) March 21, 2014
The first part of the tweet contains sage advice: developers should indeed use their own software regularly, and that will encourage them to build better software. Then, however, I took a snarky swipe at the developers who work on Oracle SQL Developer. Oracle is a soulless corporation after all, right? And it’s not as if real people work on that software, right? My tweet is in no way offensive, right?
Then I got this tweet:
@hoop33 our team uses it on a daily basis, I live in it. What annoyances can I help you with?
— Jeff Smith (@thatjeffsmith) March 23, 2014
Wow. Not so soulless after all: a real person who not only cares enough to respond to my tweet, but also chooses to ignore my snark and answer with an attitude of helpfulness and class. Properly chagrined, I explained the two issues I was having, and he asked which version of Oracle SQL Developer I was using. Um . . . it turns out that the version I have is pretty old, so he encouraged me to upgrade, and even told me the latest version that would work on my (work) Snow Leopard machine. I downloaded it, connected to a database, and then let it sit for hours. Then I ran another query. In the past, this would cause SQL Developer to hang, and I’d have to Force Quit it. With this new version, however, it automatically reconnected to the database and ran the query. Success!
Let’s look at what I did wrong:
- When I had a problem, I just felt victimized and did nothing about it. For years.
- I never bothered to look for any updates to this piece of software.
- When I got frustrated enough, I took a public swipe at the developers.
I’m a developer. I should know better. I ship buggy code. I release updates all the time that fix bugs and add new features. I don’t enjoy criticism, especially snarky criticism, and especially about something I’ve already fixed!
So, Jeff, I apologize, and I thank you for your help. And for the unspoken reminder to stay classy. I’m still hoping for a smoother, less-interactive import of updated connections, but this time I’ll ask nicely.
And, since Jeff deserves the last word on this far more than I, here’s his response when I told him the new version corrected the application’s hanging:
@hoop33 we spent a lot of time between 3.1 and 3.2 on connection stability/robustness – and handling timeouts properly.

I just bought a new MacBook Pro to replace my mid-2010 MBP. This is my first retina laptop, and it’s beautiful. I’d been waffling for awhile, but I’m glad I took the plunge.

Steps to Lock Up Linux Using Sublime Text 3:
- Log in to your Mac OS X machine.
- Install VirtualBox.
- Install a Linux virtual machine.
- Boot that Linux virtual machine.
- Install Sublime Text 3 on that Linux virtual machine.
- Launch Sublime Text 3 and open some files for editing.
- Hit Cmd+P to Goto Anything….
There you go. As we say in The Deep South, you’re locked up tighter’n a tick. You can click around, mash keys, yell, and curse, even for a long time, and you’re completely stuck.
Steps to Unlock Linux After Sublime Text 3 Has Locked It Up:
- Hit Cmd+P to uncheck the Machine > Pause (Host+P) menu item.
- Hit Ctrl+P to Goto Anything….
Don’t ask me how I know this; maybe I read it somewhere.
A $5 app isn’t expensive: Customers need to help fix the App Store economy | Macworld: “You don’t buy a Kindle just to enjoy the dictionary and manual that come pre-installed on the device. You shouldn’t buy an iPhone to enjoy only free apps, either. You’re cheating yourself, all because we’ve become conditioned to feeling that $5 is a lot to spend on an app. It’s okay to pay for good products.”
That’s the best line in a great article.
I’m astonished at how little people value software these days. “Didn’t have feature X! Complete waste of a dollar!” Yet they waste dollars willy-nilly by leaving lights on when they walk out of rooms. Great software can only be produced by great skill and great effort. Use great software, pay for it, and you’ll be happier.
I’ve released a command-line App.net client for Mac OS X: Wry. Its home page is http://grailbox.com/wry. It’s released under the MIT License, and is hosted on github at https://github.com/hoop33/wry. Check it out, and let me know what you think!
I have a Dropbox Pro account with 107.5GB of storage, an iCloud account with 15GB of storage, and free accounts with Box (50GB), SpiderOak (2GB), GDrive (5GB), SkyDrive (7GB), ASUS WebStorage (8.5GB), Cubby (5GB), and UbuntuOne (5GB). I have plenty of cloud storage space. What I don’t have is a good way to manage that space.
Each of those cloud storage options operates as an island. Most create a directory in my home folder that its daemon syncs to the cloud. I can set preferences on my various devices for what gets synced inside that folder, but that folder is its own beast. If I want to save something to the cloud, I have to decide which cloud service to sync to and either save to that directory or otherwise upload to that service.
I got to thinking: what about an app that virtualized all that storage into a single virtual drive? This app would take care of managing which service to save files to, depending on file sizes and free space, and could even replicate files across services for my peace of mind. Sounds fun to build and definitely useful.
As I thought about it, though, I realized this app would have two issues:
- It doesn’t seem very sporting. These cloud services need paid customers to stay afloat. My proposed app could entice people to never pay for any cloud services, mooch the free services, and let the app take care of never running out of space.
- The primary target audience would be the people mentioned in objection #1, and they’re cheapskates. Not only wouldn’t they pay for cloud storage, they also wouldn’t pay me for the app, either.
TL;DR — Turn off Path Finder desktop to use GeekTool.
I’ve been meaning to install GeekTool on my new Mac that I bought, um, over two years ago. Time flies. Anyway, I installed it from the App Store, ran it, and tried to drag an icon to my desktop as the instructions say. I kept experiencing these symptoms:
When opening GeekTool, I am welcomed to a blank Properties box with just “Geeklet Settings”. Many tutorials have told me to drag either “file” “Images or “Shel” onto the desktop. I do this and nothing happens. The little black box that appears when you click and drag bounces back up to the GeekTool 3 preference box.
The remedy most often listed was to uninstall and reinstall, but before I did that, I realized: I wasn’t actually dropping the icon on my desktop. I was dropping it on my Path Finder desktop, which I enable in Path Finder’s settings (Features > Show Path Finder desktop). That makes a difference! I turned off the Path Finder desktop (admittedly, I don’t know what it offers, so I don’t know what I’ve lost), and BOOYAH! Dropping GeekTool icons now works.
