I'm woring on a personal research project and would like to know if there are lilypond parsers for python available or I'll have to create my own. Just in case you are wondering: I don't need to typeset the content of the lilypond file, just understand what's written in the file (what notes, what duration, when in time to play each one, etc).

How can I get this on a python program so I can manipulate it as an array?
I have this command in ksh:
1. typeset -i INTEGER INTEGER=aaa In all platforms except of Linux it is failing and return exit code 1 Why in Linux it is not failing? I must it for my number tests
2. The same for printf command. Only in Linux the bellow command is not failing: printf "%d" aaa
My employer issues pdf files with everyones work schedules. I copy the content and save it as plain text in a file called unformatted (hope to be able to automate this step someday). Im working on a SED script that reduces unformatted to only display what I want to see and saves the result in a file Iïve named formatted. After that I have to manually copy formatted and save it with that days date as a filename e.g. 2011-02-25 or whatever day is scheduled in the pdf, for use on a mobile device (Nokia N900). I noticed that the date occurs on certain lines in the file so I added a line like:
sed -n 's/^Date: (201[1-9])/([0-1][0-9])/([0-3][0-9]).*/1-2-3/p' < unformatted >theDate
That creates a file theDate with the date in it that I wish to use as the filename for this particular instance. So I would like to skip the file formatted all together and have the sed- script write to a new file using the content of the Date as a filename, but how do I make that happen? And of course it would be more elegant if I could skip the intermediate theDate file as well.
I wanted to copy one file to multiple new files. I have an idea to write a script and do the operation. But here i m looking for any particular command to do this operation.

View 1 Replies View RelatedI decided to try making a programming language again after my last unsuccessful attempt, so now I figured how to write a good AST and it works great when the nodes are hard-coded into a test program. But to make a language out of it, I need a parser to build the tree according to an input file. I ran into a problem here:
YACC input file:
Code:
%{
#include "nodes/allnodes.h"
#include "Node.h"
int vars[26];
%}
%token SEMICOLON INTEGER VARIABLE IF WHILE DO OPAREN CPAREN OBRACE CBRACE
%right ASSIGN
%left NE
%left PLUS MINUS
%left TIMES DIVIDE
%% .....
As you might see, each nonterminal creates a Node* object and uses it as its value. The problem is that the literal tokens, however, don't return Node*'s and I don't know what to do. I would like to be able to convert literal tokens to nodes in the Lex file (which would avoid the problem), but the problem is with the assignment operator, which takes a Node* for the right-hand side and a variable name (not a Variable Node, because they just evaluate the the variable's value and you can't change the variable with them) for the left hand side.
I'll show the code first:

I've run into a little problem, for which I seem to be unable to find an answer. The concept is the following: one machine runs a python script which advertises itself as 'OBEX File Transfer' and receives incoming data, using the Lightblue python module. The script itself is slightly different, but here's an example which effectively works in the same way:
[Code]....
print "Saved received file to MyFile.txt!" This works fine, though I would like to retain the original filename that is being sent to the machine, instead of overwriting a fixed file. Generating a new name wouldn't be such a problem, if I could get the MIME type or filename which is (presumably) being sent in the header of the request. Does anyone know of a way in python to receive incoming files and retain their filenames via Bluetooth?

View 4 Replies View RelatedI wrote a C++ program that uses two different parsers. The first parser is reading program arguments from command line:./mybin arg1 arg2 ...then during program execution there's an interactive prompt asking for more parameters:

I'm trying to search for several strings, which I have in a .txt file line by line, on another file.
So the idea is, take input.txt and search for each line in that file in another file, let's call it rules.txt.
So far, I've been able to do this, to search for individual strings:
Code: Select allimport re
shakes = open("output.csv", "r")
for line in shakes:
  if re.match("STRING", line):
    print line,
How can I change this to input the strings to be searched from another file?
So far I haven't been able to.
I have a Python script that copies a couple of DLL's and EXE to a directory before running the EXE. It can be a fresh copy or the files can already be in the target directory and are then overwritten. The script uses shutil.copy() to copy the files and that works but as the files are copying processing continues and the script tries to run the files mid copy, causing an error.
I need a way to wait for the files to finish copying before the script continues. Putting the thread to sleep isn't good enough, calling os.system("copy ...") also doesn't work, using os.path.exist() won't work because the file will exist during the copy.

Probably a stupid sounding question, but bear with me please. I need to use the link grammar parser in order to do some part of speech tagging. It's freely available and works once you run the makefile or 'make' it or however it's correctly said. Thing is, it has a C API which I intend to use. And once I ran a bit of the sample code given in the documentation it gave a whole host of errors. This is very confusing because I'm including the path for the folder that has all the header files.
gcc -I/path/include/ filename.c. But it still gives me errors about not being able to find things that are clearly defined there. An hour of trudging around the internet tells me I need to 'compile' the API first. I'm not exactly sure how or if I'm supposed to do that. If someone could just shed light on this it would be greatly appreciated. I grow increasingly cynical to the musical swell of my tiny brain rattling in my skull.
I'm trying to develop an html template parser employing Flex & Bison, but now I found a problem and I don't know if surrender, so let's see if you can guide me to the solution (if any).
[Code]...
(Here I simplified the code to make only print what it gets, but it returns a token and the text to the bison program). Now my problem is that I would like to get the unknown characters as an unique string. [using the flex file above, returns char by char all HTML code that is not a comment!].
So, Could it be possible to make a flex rule that gets the HTML code?. It is not necessary to check if HTML code is correct I do it (before parse) using expat. Also there is no need to check the resulted code it will be done by the parser or compiler of the used language.
I know that are a lot of tools that uses this kind of templates in all languages and systems... but I'm just exercising my pour flex&bison skills. Also, using my current flex file, I have to remove the string "<!--MARKUP" from the beginning and "-->" from the end of returned string to bison... But in reality, if I could manage the HTML code as a flex rule, I could solve that sednding to bison an start Token, the code and and end token.

I am developing a program in a system where the Linux does not take care of the sync command automatically. So I have to run it from my application always I save some data in the disk, which in my case is a 2GB sdcard. It is true that I can make the operation system takes care of the syncronization, using a proper mount option, but in this case the programm's performance drops drastically. In particular I use the shelve module from Python to save data that comes from a socket/TCP connection and I have to deal with the potencial risk of the system being turned off suddenly Initially I wrote something like that to save data using shelve:
Code:
def saveData(vo)
fd = shelve.open( 'fileName' , 'c')
fd[ key ] = vo
fd.close()
os.system("sync")
But that takes too much time to save the data. Note that I use the sync from the OS every time I close a file to prevent data corruption in the case of the "computer" being turned off with data even in the buffer. To improve the performance I made something like that:
Code:
def saveListData( list )
fd = shelve.open('file_name', 'c')
for itemVo in list:
fd[itemVo.key] = itemVo
fd.close()
os.system("sync")
Thus, first I saved an amount of objects in a list then I open the file and save the objects. In this way I have to open the file just one time to save a lot of objects.However I would like to know if adding a lot of objects before closing the file would increase the risk of data corruption.I known that turning off the system after fd.close() and before os.sync may cause problems. But what about turning off the system after
Code:
fd = shelve.open('file_name', 'c')
but before fd.close()?
I'm trying to read content of file to variable and use this variable in for loop. The problem is, when I have c++ comment style in file - /*. Spaces in line are also interpreted as separated lines.
For example:
Code:
Changing $files to "$files" eliminate these problems but causes that whole content of variable is treated as one string (one execution of loop).
