Let’s say you have a string evaluated into a HTML template that contains newlines, like "getting\n\things\ndone" and you want those newlines to be reflected in the presentation. Like this: getting things done We can solve this with the following CSS on the string’s containing element: white-space: pre-wrap; With pre-wrap, “[s]equences of white space are preserved. Lines are broken at newline characters, at [breaks] and as necessary to fill line boxes.” white-space docs

The local environment is a great place to iterate on a CircleCI configuration. You’ll catch errors faster than pushing to CI, and help drive a fast, iterative configuration process. Install the CircleCI CLI via Homebrew (or any package manager of your choice): $ brew install circleci Then, in the same directory as your .circleci/config.yml, run: $ circleci config validate # Config file at .circleci/config.yml is valid

When I upgrade ASDF, I sometimes get an error like this when I try to run a command: /Users/jakeworth/.asdf/shims/jq: line 3: /usr/local/Cellar/asdf/0.9.0/libexec/bin/asdf: No such file or directory The issue is that I’ve upgraded ADSF to v0.10.2, but the jq shim doesn’t know that and can’t find it in a directory called “0.9.0”. This issue persists even after running asdf reshim. My solution is to force ASDF to rebuild shims directory by renaming it. A rename lets me get back to where I am now, in case I need to. ...

I use Vim’s spell feature when writing blog posts. Very often, the first suggestion it makes is the one that I choose. Consider a word like ‘Rubysit.’ My dictionary contains the word ‘Rubyist’ (naturally) and that’s what Vim spell is going to suggest to me first. For transposition errors like this I’d like to skip the word picker when possible. To automatically choose the first suggestion, in normal mode put your cursor over the word and type 1z=.

Something I took for granted at Hashrocket was the file that configures Exhuberant Ctags. Without configuration, recursive tag generation will tag many things and cause problems. overindex badly. Here’s how you configure Ctags to ignore things: /ctags.cnf (on MSDOS, MSWindows only) /etc/ctags.conf /usr/local/etc/ctags.conf $HOME/.ctags $HOME/ctags.cnf (on MSDOS, MSWindows only) .ctags ctags.cnf (on MSDOS, MSWindows only) If any of these configuration files exist, each will be expected to contain a set of default options which are read in the order listed when ctags starts, but before the CTAGS environment variable is read or any command line options are read. This makes it possible to set up site-wide, personal or project-level defaults. Here’s the head of my root .ctags, which even this far in is excluding a lot: ...

From normal mode, N% will jump you to that percentage of the file. So 50% jumps to halfway through the file.

Unused dependencies are bad: they increase the size of your project, slow down processes, require maintenance, and send incorrect messages to fellow developers about what’s important. To get find unused dependencies in Ruby, I’ve been using gem stale: gem stale gem stale list gems along with most recent access times. If the last access time was the day you set up the app, that gem is a candidate for removal.

The longer I program (ahem), the bigger I want my terminal fonts. I think most programmers should be using a bigger font than they are. Complicating matters, the standard font for iTerm is miniscule on a computer monitor. Today I discovered iTerm’s ‘View > Size Changes Update Profile’ feature. When enabled, changes to your font size via ⌘ + and ⌘ - will be applied to your iTerm profile. The next time you open iTerm, the new font size will persist.

Hit K on a keyword, and Vim looks up the program under the keyword. It’s a bit jarring because Vim appears to shell out from your buffer to show the definition. To see that man page in Vim, load the man.vim plugin from command mode or in your .vimrc: :runtime! ftplugin/man.vim Now, you can read man pages as a Vim buffer: :Man curl
