Hi Can someone give example of parsing using zetta-parser for the case that the input stream is intermittent (i.e. possibly incomplete at a particular moment). The author of zetta-parser refers to this very possibility in his readme (for example parsing messages arriving at a socket or such).
My particular application is interacting with several command line programs in MS Windows. So I need to parse the characters coming from the program's output streams (stdout and stderr). The interaction really is interactive, so for example, when I start the CL program, I might get a lot of lines of output followed by a prompt "TypeNow>" kind of thing. So I want the parser to skip the lines and return when it sees the prompt. Now I might send a character or string to the CL program's stdin and then get more (differently structured) output to parse. And so on. I cannot change these CL programs because they are provided by third parties; they were written with a view to interacting with a human, not a program. It seems to me that this kind of parser is perfect for this job - but I'm a newbie at monads etc so I don't know how to express it in zetta-parser syntax. (I'm also not familiar with Haskell). BTW The Win32 treatment of the streams associated with a command line program is completely broken, in the sense that the stdout stream is *buffered*, so as it stands it is not possible to interact like this with a console program. You don't get to see the buffered output until either the buffer fills up, or the program terminates. Either way, it's not interaction. This of course also carries over the Java version using java.lang.RunTime.exec. If one tries to run an interactive program by this means, it just hangs up. In order to achieve interactivity I have had to create a truly horrible CL program runner written in C (which I start and interact with via a JNI interface) that infers the output from stdout and stderr by continually examining the console output buffer (i.e. the screen).
