Eric,
Below the dotted line there are two functions.
"csound_filter ()" extracts and formats instrument blocks from
csound files and writes the output to another file. (If called without
an output file name, the output displays on the screen).
The second function, "make_instrument_dictionaries ()", takes the
file generated by the first function and makes two dictionaries. One of
them lists instrument ids keyed on instrument description, the other one
does it the other way around, listing descriptions by instrument id.
Instrument ids are file name plus instrument number.
You cannot depend on this system to function reliably, because it
extracts information from comments. I took my data from
"ems.music.utexas.edu/program/mus329j/CSPrimer.pdf" the author of which
happens to lead his instrument blocks with a header made up of comment
lines, the first of which characterizes the block. That first line I use
to make the dictionaries. If your data doesn't follow this practice,
then you may not get meaningful dictionaries and are in for some
hacking. In any case, this doesn't look like a job that can be fully
automated. But if you can build your data base with a manageable amount
of manual work you should be okay.
The SE filter likewise works depending on formal consistency with
my sample. If it fails, you may have to either tweak it or move up to a
parser.
I'll be glad to provide further assistance to the best of my
knowledge. But you will have to make an effort to express yourself
intelligibly. As a matter of fact the hardest part of proposing
solutions to your problem is guessing what your problem is. I suggest
you do this: before you post, show the message to a good friend and edit
it until he understands it.

Frederic

Re: newbe's re question
These are csound files. Csound recently added python as a scripting
language and is allowing also allowing csound calls from outside of
csound. The nice thing about csound is that instead of worrying about
virus and large files it is an interpiter and all the files look
somewhat like html. 4,000 virus free instruments for $20 is available
at
http://www.csounds.com and the csound programming book is also
available. The downside is that csound is can be realy ugly looking
(that is what I am trying to change) and it lets you write ugly looking
song code that is almost unreadable at times (would look nice in a
grid)

Eric,
From your problem description and your code it is unclear what
exactly it is you want. The task appears to be rather simple, though,
and if you don't get much useful help I'd say it is because you don't
explain it very well.
I believe we've been through this before and your input data is
like this
data = '''
;
; test.csd - a Csound structured data file
-W -d -o tone.wav
;optional section
Before 4.10 ;these two statements check for
After 4.08 ; Csound version 4.09
; originally tone.orc
sr = 44100
kr = 4410
ksmps = 10
nchnls = 1
instr 1
a1 oscil p4, p5, 1 ; simple oscillator
out a1
endin
; originally tone.sco
f1 0 8192 10 1
i1 0 1 2 1000 ;play one second of one kHz tone
e
Question 1: Is this your input?
if yes:
Question 1.1: What do you want to extract from it? In what format?
if no:
Question 1.1: What is your input?
Question 1.2: What do you want to extract from it? In what format?
Question 2: Do you need to generate output file names from the data?
(One file per instrument?)
if yes:
Question 2.1: What do you want to make your file name from?
(Instrument number?)

Eric,
I'm beginning to enjoy this. I'm sure we'll sort this out in no
time if we proceed methodically. Imagine you are a teacher and I am your
student. This is a quiz. I have to take it and you need to explain to me
the problem you want me to solve. If you don't explain it clearly, I
will not know what I have to do and cannot do the quiz. If you answer my
questions above, your description of the problem will be clear and I can
take the quiz. Okay?

I want to pass the file name to the subroutine and return a comment
string if it is there maybe it should be simplier. I probily should
have the option of grabbing the comment in other related routines. I
am pretty ambitious with the main program. I did notice some code in
tcl that would be usefull to the app If I compile it.. I am probily
not ready for that though..

Eric,
From your problem description and your code it is unclear what
exactly it is you want. The task appears to be rather simple, though,
and if you don't get much useful help I'd say it is because you don't
explain it very well.
I believe we've been through this before and your input data is
like this
data = '''
;
; test.csd - a Csound structured data file
-W -d -o tone.wav
;optional section
Before 4.10 ;these two statements check for
After 4.08 ; Csound version 4.09
; originally tone.orc
sr = 44100
kr = 4410
ksmps = 10
nchnls = 1
instr 1
a1 oscil p4, p5, 1 ; simple oscillator
out a1
endin
; originally tone.sco
f1 0 8192 10 1
i1 0 1 2 1000 ;play one second of one kHz tone
e
Question 1: Is this your input?
if yes:
Question 1.1: What do you want to extract from it? In what format?
if no:
Question 1.1: What is your input?
Question 1.2: What do you want to extract from it? In what format?
Question 2: Do you need to generate output file names from the data?
(One file per instrument?)
if yes:
Question 2.1: What do you want to make your file name from?
(Instrument number?)
Regards
Frederic

Did you read the HOWTO on regular expressions yet? It's included with
the standard documentation, but here's a link:
http://www.amk.ca/python/howto/regex/
Now, onto the issues:
1) The escape character is \, not /. Use "\d" to match a number.
2) I'm not sure I understand what you're trying to extract with your
regex. As it is, the expression will return a list containing one item,
a string identical to the line being matched up to, but not including,
the first number. The rest of the line will be discarded. Try Kiki, a
tool for testing regular expressions, before burying the expression in
your code.
3) Python has built-in booleans: True and False, no quotes. Use them so
that you don't get flamed on forums.
4) I don't claim to be a Python guru, but here's a massaged version of
the function you gave:
[code]
def extractCsdInstrument (inputPath, outputPath, instrId):
""" Takes a .csd file, grabs info for instrument ID and writes to
file. """
src = open(inputPath, 'r')
dst = open(outputPath, 'w')
for line in src:
if "instr" in line:
info_comment = line.split(";", 1) # [info, comment]
# Extract integers
instrInfo = re.split(r"[^0-9]*", info_comment[0])
# Check the second number in the line
if instrInfo[1] == str(instrId):
dst.write(instrInfo.append(info_comment[1]))
src.close()
dst.close()
[/code]
I didn't check if this actually works, since I don't know what a .csd
file looks like. There are of course other, better ways to do it, but
hopefully this leads you in the right direction.
5) Please, read the documentation that came with your Python
installation. Reading up on string methods etc. ahead of time will save
you much more time than trying to slug through it. Also consider using
a text editor with syntax highlighting; that will help catch most
obvious syntax errors during coding.

Re: newbe's re question
Hi Eric, Don't let people offput you from learning python. It's a great language, and is fun to use. But really, George does have a point -- if you want to learn python, then the best way is to swim with the tide rather than against it. But still, don't worry too much about being pythonic and whatnot (many people would disagree with me here), just write the code that _you_ (and your team) feel the most comfortable with, and helps you be the most productive. But again, many of the conventional pythonic ways to do things are such because people have tested various ways and found those to be the best. So don't just blow off convention, either. Find a happy medium between your coding style and the conventions, and then you'll really become as productive as you can be. That's my opinion. And only my opinion. But if it helps you too, that's good. :) Ps. Do have a look at the tutorials and other guides available, they should help you out alot (e.g., the regexp tutorial [1]). [1] http://www.amk.ca/python/howto/regex/ Regards, Jordan -- http://mail.python.org/mailman/listinfo/python-list

better to offend a python than a rattlesnake (you have to see the cwa
rattlesnake shirts shirts compared to the python shirts) :)
As long as it will run but I feel like I am just converting it to
something that feels like c somewhat but I am learning the commands
(hopefully).. hard to get a good chapters with questions at the end
without cash... I am happy even if the code isn't pythonic if it runs
with this.
import csoundroutines
extractCsdInstrument("bay-at-night.csd", "test.orc", 1)

If you think this is the only problem in your code, think again; almost
every other line has an error or an unpythonic idiom. Have you read any
tutorial or sample code before typing this python-like pseudocode ?
