Ok, disclaimer. As of writing there aren’t exactly 100+ cheatsheets available on errtheblog‘s wonderful new cheatsheet tool, but its only a matter of time til my title is correct. Then I will rewrite this introduction paragraph and I will be the earliest dating author to declare how large and wonderful
cheat?” All your cheatsheets on the command line – where you are already working.
Check this out:
>cheat sprintf sprintf: %s => string %d => number %f => float >cheat strftime strftime: %a - The abbreviated weekday name (``Sun'') %A - The full weekday name (``Sunday'') %b - The abbreviated month name (``Jan'') %B - The full month name (``January'') %c - The preferred local date and time representation %d - Day of the month (01..31) %H - Hour of the day, 24-hour clock (00..23) %I - Hour of the day, 12-hour clock (01..12) %j - Day of the year (001..366) %m - Month of the year (01..12) %M - Minute of the hour (00..59) %p - Meridian indicator (``AM'' or ``PM'') %S - Second of the minute (00..60) %U - Week number of the current year, starting with the first Sunday as the first day of the first week (00..53) %W - Week number of the current year, starting with the first Monday as the first day of the first week (00..53) %w - Day of the week (Sunday is 0, 0..6) %x - Preferred representation for the date alone, no time %X - Preferred representation for the time alone, no date %y - Year without a century (00..99) %Y - Year with century %Z - Time zone name %% - Literal ``%'' character t = Time.now t.strftime("Printed on %m/%d/%Y") #=> "Printed on 04/09/2003" t.strftime("at %I:%M%p") #=> "at 08:56AM"
All your cheatsheets are now available via the console.
“All of them”? Yes, well no, but yes. The cheatsheets are written up on a public wiki, and the
cheat command retrieves the requested text, caches it locally, and fills your ASCII virtual world with the cheatsheet. So, want to add another cheatsheet? Create a new wiki page, insert cheatsheet, save, done.
“But what cheatsheets are available? How do I know what I can get my dirty, cheating hands on?”
Watch, young reader, and gasp with amazement:

To my thinking,
cheat is a next-generation
man tool. Instead of bundling manual pages with your application/gem/library, you could now host a set of live manual pages. Perhaps errtheblog or RubyForge could provide a separate wiki + command line for gem manual pages (hint: gemman or mangem)?
