For ordinary splitting, you should start with ;.
yes, definition here - http://www.jsoftware.com/help/dictionary/d331.htm
This definition uses a bevy of terms that are lost on me but I hope they become clear with time.
rather than ;: . For example: <;._1 ' dazlious eleemosynary deipnosophist aba' +--------+------------+-------------++---+ |dazlious|eleemosynary|deipnosophist||aba| +--------+------------+-------------++---+
my original question was about choosing the split delimiter... how would you split "terrence234brannon" by the regular expression \d+ for instance? not only that, but I get a truncation when I try this unless the string starts with a space. t terrence brannon <;._1 t ┌───────────────┐ │errence brannon│ └───────────────┘ and the split delimiter should be settable to a series of contiguous whitespace, not just a single whitespace character. Finally most people would trim the leading and trailing whitespace from the string before splitting it...
You will not find an actual definition of "unit axis" in the dictionary. The authors depend on your good sense to figure out what it is. (Unit means 1.) I think you mean to look at the dictionary page for ;: but you quoted the page for ,: . ----- Original Message ----- From: Terrence Brannon <[EMAIL PROTECTED]> Date: Wednesday, March 28, 2007 8:39 am Subject: [Jgeneral] ;: -- is the word separator parameterizable? > Most agile languages offer a split() function which can split a string > on any delimiter, with a series of whitespace as the default. > > Is it possible to specify what the verb ;: will use to split the > string? > Finally, the dictionary description of ;: is very unlike what I > expected: > <definition url="http://www.jsoftware.com/help/dictionary/d322.htm";> > ,:y adds a leading unit axis to y , giving a result of shape 1,$y . > </definition> > > -- the above definition does not define unit axis, nor does it > make a > hyperlink to those terms, so it confuses me. > > The Lab: A Taste of J (1) says that it chops a string into words, each > with a box. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
