Since the gem ecosystem keeps changing, and since I don’t write new programs very often, here’s a list of my favorite gems for developing command-line interface tools.<\/p>\n\n\n\n
Option parsing gem: slop<\/a>. (Since micro-optparse<\/a> looks moribund; see here<\/a>.) But (looking at programs I’ve written) I also seem to like Debugging output (not the same as logging): pastel<\/a><\/p>\n\n\n\n Invoking system functions gem: tty-command<\/a>. (See also tty-config<\/a> and tty-file<\/a>.) But sadly, tty-command (or how I’ve used it) gets me warnings that bellyache about the 2.7 named argument splat problem<\/a>.<\/p>\n\n\n\n Wrapper for ImageMagick: About a decade ago, I couldn’t get RMagick<\/a> (rubymagick?) to compile and I’ve never gotten around to checking back. For awhile I used Proper Capitalization of Text Strings That Are Titles: titleize<\/a>.<\/p>\n\n\n\n Parsing Biblical references (e.g., Romans 8:39 and Genesis 12:1-4): pericope<\/a>.<\/p>\n\n\n\n Plus Kramdown<\/a> and HAML<\/a> and SASS<\/a> (which is no longer written in Ruby).<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" Since the gem ecosystem keeps changing, and since I don’t write new programs very often, here’s a list of my favorite gems for developing command-line interface tools.
