behind the reel: Vim Tips: Indent Object and Visual Selection Jumps
We highly recommend the “vim-indent-object” plugin (included in Janus). It allows you to act on indentation levels as text objects. For example
1 def complex_method 2 [1,2, 3, 4, 5, "👾]", "🎃]"].each_with_index do |i, n| 3 0.upto(n) do |j| 4 result...
At SideReel, breaking the build is no laughing matter, if you forget to run rake all, and the build breaks, you’ll be forced to carry around, a big giant rake.

The following command in your vimrc will map <Leader>h in visual mode to dump the html for the syntax highlighted version of the selected region and open a web browser displaying it. (Especially useful for copying to email)

(So to switch two panes in a vsplit use Ctrl + W (shift) H or L) .
Additionally, you can use Ctrl+W (shift) R to switch panes, R will rotate the pane arrangement.
behind the reel: Vim Tips: Jump lists
Vim keeps track of everywhere your cursor has been in every file (up to 100 locations). To move forward and back through editing locations, you can use Ctrl+I (forward) and Ctrl+O (backward). This will also work across all open files. This is particularly useful with the shortcuts “gf” (You hit…
Get a text when your tests finish running
To send a text message when a process is no longer present, you can use the below command. This will only work on MacOSX and it requires that you determine your SMS gateway address. For an AT&T number at 415-291-0000 the number would be 4152910000@txt.att.net
