Mike, Try !$s The exclamation point is a not symbol, just as in C. liblouis has variables that can be used to keep track of what you are doing. Here is a paragraph from liblouis-guide.html <p># (number sign or crosshatch): test or set a variable. Variables may be set by one context or multipass opcode and tested by another. Thus, an operation that occurs at one place in a translation can tell an operation that occurs later about itself. This feature will be used in math translation, and it may also help to alleviate the need for new opcodes. This suboperand is valid everywhere.</p> On Tue, Mar 18, 2008 at 11:27:28AM -0700, Mike Sivill wrote: > I would like to know if there is currently an element for the context opcode > that includes all characters except space.
