Don’t hate on Python. It will come silently in the night and indent you, and then you’ll be sorry.

This is SO COOL! Thank you tons!

Hey, this is pretty cool! When can we expect the source code for the interface and for the backend?

Oops, just found it. Nevermind that :)

I had to change HOMEPATH in def sheets; end to HOME to make it work on win32. HOMEPATH doesn’t have the HOMEDRIVE which seems to make mkdir choke.

Some line wrapping would be nice, dooing it by hand is ugly and hard.

The ENV[‘HOMEPATH’] doesn’t seem to be the best ENV option (that is, it isn’t working :)

HOMEPATH=\Documents and Settings\Nic Williams (note: no drive path)

Alternatives: USERPROFILE=C:\Documents and Settings\Nic Williams

Or combine: HOMEDRIVE=C: HOMEPATH=\Documents and Settings\Nic Williams

Anyone have thoughts on which is best (and/or why HOMEPATH might be incorrect on my win32 laptop?)

Nic

Yeah, what yerejm said… :)

I added a validations and a single_table_inheritcance one for all to enjoy.

I like to work at both the command line and in my text editor (JEdit). If you are using JEdit and want to access these cheat sheets right from your text editor I put together the following BeanShell script. It will execute the cheat command with the name you give it and put the output in a simple dialog box.

My Java is quite rusty so this may not be the best implementation:

String sheet = Macros.input(view, “Enter sheet name”); Process proc = Runtime.getRuntime().exec(“cheat “+sheet); BufferedReader output = new BufferedReader(new InputStreamReader(proc.getInputStream())); StringBuilder info = new StringBuilder(); while( (line = output.readLine()) != null ) { info.append(line+”\n”); } Macros.message(view, info.toString());

Simply map this to a key command (I have it mapped to Ctrl-Shft-C) and you can quickly bring up your cheat sheet in Jedit.

Cool. What a nice idea!!!

These are flippin’ sweet. Absolutely a great idea. I can never remember strftime.

Chris- I wrote up a blog post asking people to test the windows new windows cache code at (http://concentrationstudios.com/articles/2006/09/02/cheat-tests) I am going to try writing up some tests soon. At least I have some test stubs :)

Dugg! http://digg.com/programming/Ruby_Help_on_the_Command_Line

v1.0.1 works great on Win32 now. Thx guys!

Here’s a TextMate command I set up:

word=${TM_SELECTED_TEXT:-$TM_CURRENT_WORD} echo “

";
/usr/local/bin/cheat $word;
echo "

Ok, that got mangled. See my blog entry:

http://weblogs.litmusgreen.com/ed/archives/002498.html

Can you include the whole cheatsheet in the RSS feed?

• What’s the password?

Harriet: The password is jalapeno.

Dr Nic: Done!

Very cool, I just scraped the relations docs for rails and dropped those in since I’m always lookin’ em up. Now to hook it up with TextMate (the one true $EDITOR)

Great stuff!

Idea: would be nice to have an URL property for each cheat. Like where can we get the code. >cheat microformats_helper—url

Any reason it’s not up on rubyforge? appending that—source to the gem command line is way too much work :-p

That’s cool!

Blaine, it’s on rubyforge. Just $gem install cheat :-)

cheat sheet—add cheat sheet—edit

Someone please fix my horrible horrible hack :)

Thanks for making this! I have one question though, how do you get mac keyboard symbols to show up in the terminal? For example, some of the symbols in the textmate_rails cheat sheet? Thanks!

Kick ass!

Ok, now implement all of my MAN pages :)

if you want to call cheat from within cygwin bash but you are using the windows version of ruby (don’t ask ;) then the following additions to your .bashrc will make it work without having to re-write the ruby:

: ${HOMEDRIVE:=c:}; export HOMEDRIVE : ${HOMEPATH:=$(echo ~)}; export HOMEPATH alias cheat=’cheat.cmd’

I’m having issues getting cheat to work with Instant Rails. I was able to install it using the ‘gem install cheat’ command but when I run it mkdir seems to choke with a ‘No such file or directory error’ Any help will be appreciated. Thanks.

How to store in local?

This is great! I’ve installed it successfully and ‘cheat migrations’ works a treat but ‘cheat cheat’ doesn’t:

$ cheat Looking for help? Try http://cheat.errtheblog.com or `$ cheat cheat’

$ cheat cheat Error!: Cheat sheet `cheat’ not found.

Any ideas?

man strftime ?? It is just calling the C function

I love cheat :) and I love vim :) so there you go: a cheat wrapper for vim

Cheers!

I added a cheat function to my ”.bashrc” file, so I got paging without typing “more”

function cheat() { /usr/bin/cheat ”$@” | more; }
