It's not trying to load the whole file in memory. It caches one copy of the first bits of a new line (things up to "fruit") and the list of 'items' that follow. When the first bits change, the record, with the summary of items, is written and the caching/list starts anew (list = ""). So, the only significant amount of "stuff" that is ever held in memory is the list of items.
Now, if that list is huge, then the programme could be amended to write them out as it finds them. My assumption was that the list wasn't going to be more than 1 or 2 K.
---------- Post updated at 21:55 ---------- Previous update was at 21:42 ----------
Turns out that printing the list as we go is a simpler programme; just didn't see it that way the other night.
Seems simple but I am having difficulty with this one: I am trying to write a single command line argument (which will be a path) - the program should print out the owner of the path.
I can not get anything I write to run.
Please help. (5 Replies)

LIQUIDSOAP(1) General Commands Manual LIQUIDSOAP(1)NAME
liquidsoap - a multimedia streaming language
SYNOPSIS
liquidsoap [options] [script|expression]
DESCRIPTION
Liquidsoap is a programming language for describing multimedia streaming systems. It is very flexible, making simple things simple but
giving a lot of control for advanced uses. Liquidsoap supports audio, video and MIDI streams, and a wide range of input/output operators
including Icecast and various soundcard APIs. It can perform a broad range of signal processing, combine streams in various ways, support
custom transitions, generate sound procedurally... and all this can be assembled as you wish. Input files can be accessed remotely, or
even be synthesized on the fly using external scripts such as speech synthesis. Finally, interaction with a running liquidsoap instance is
possible via telnet or socket.
Liquidsoap scripts passed on the command line will be evaluated: they shall be used to define the streaming system to be ran. It is possi-
ble to pass multiple scripts; they will all be ran successively, and definitions from one script can be used in subsequent ones. A script
will be read from standard input if - is given as script filename. Information about scripting liquidsoap is available on our website:
http://savonet.sf.net/
If the parameter is not a file it will be treated as an expression which will be executed. It is a convenient way to test simple one-line
scripts. When running only one-liners, the default is to log messages directly on stdout rather than to a file.
OPTIONS -
Read script from standard input.
-- Stop parsing the command-line and pass subsequent items to the script.
--debug
Print debugging log messages.
--dynamic-plugins-dir path
