OS-X Shortcuts for Grails (and Other Stuff)

I use bash and vi basically as my IDE, so here are a few of my favorite functions. Hopefully people out there can use these functions as a basis to customize their own shell to really be maximally productive.

This is a straightforward Hamming encoding of one of my most common commands.

alias g='grails'

This prints out the bytecode of a Java class file, along with all the extra noise possible.

alias bytecode="javap -c -l -private -s -verbose"

And shorthand for opening a file read-only, because sometimes you don’t want to break stuff.

alias vir="vi -R"

Open a file that’s not the SVN copy or the compiled *.class file that starts with the given name.

function vif {
  FIND_ME="$1*"
  vi `find . -iname $FIND_ME -and -not -iname '*.svn*' -and -not -ipath '*/.svn/*' -and -not -iname '*.class'`
}

This fires off testing for the app. This will be a lot easier in Grails now that plugins can hook into the test-app command: looking forward to that.

function gta {
  rm -rfv stacktrace.log ./test/reports ./test/reports-functional
  grails clean
  #time grails functional-tests
  #mv ./test/reports ./test/reports-functional
  #open ./test/reports-functional/html/index.html
  time grails run-webtest
  time grails test-app $@
  open ./test/reports/html/index.html
}

This prints out the error codes, as documented by errno.

function errcodes {
  perl -MErrno -e 'my %e= map { Errno->$_()=>$_ } keys(%!); print grep !
    +/unknown error/i, map sprintf("%4d %-12s %s".$/,$_,$e{$_},$!=$_), 0..
    +127'
}

And, courtesy of Ruby.MN, this one looks up a word in Apple’s Dictionary.

function dict {
  open "dict://$1"
}

And this one (for OCaml) looks up the interface for a library.

function mli {
    TARG=`ocamlfind query $1`
    vi -R $TARG/$1.mli
}
