Hello.
Anyone have an idea how to parse txt file in format

Text file parsing and output

Hi,
I'm extremely new to Java and need to read and parse a text file and generate a new text file with modifications as follows:
1. Ignore and rewrite comments
2. Ignore and rewrite compiler commands
3. (a) Modify function prototypes be removing their return values, if any,
(b) append an '_VAR' to the function name and args
(c) add an ampersand to the args when passed by reference
sample input file:
/***** comment *****/
#if (INCLUDE_STATIC_BUILD == OS_FALSE)
extern OS_MEMORY_POOL *MEM_Non_Cached;
#endif
UINT16 TLS_IP_Check (const UINT16 *s, UINT16 len);
INT32 MEM_Copy_Data(NET_BUFFER buf_ptr, const CHAR HUGE buffer, INT32 numbytes, UINT16 flags);
sample output file:
/***** comment *****/
#if (INCLUDE_STATIC_BUILD == OS_FALSE)
extern OS_MEMORY_POOL *MEM_Non_Cached;
#endif
UINT16_VAR = TLS_IP_Check (&UINT16_VAR, UINT16_VAR);
INT32_VAR = MEM_Copy_Data(&NET_BUFFER_VAR, name, INT32_VAR, UINT16_VAR);
I would appreciate any help!
Thanks.

Writing To A Specific Text File Line

In a program I am writing I need to be able to write to the end of a specific line in a textfile. I'm not sure of any particular way to do this apart from perhaps rewriting the whole textfile which would be a pain to do. Does anyone know of a simpler way of how to do this?

RandomAccessFile would help somewhat; with it you could overwrite at a given location by moving the file pointer. The problem with this is it still doesn't solve your case, which is appending. Files are essentially large arrays of data, so you can't easily insert data in the middle of it without having to rewrite the remaining portion of the file.

Find Change through external text file

Hello folks
I am bit pretty in InDesign scripting so could you please look into this.
How can i change any particular text field in Indesign CS3 document from text file.
I do have find change script but for each InDesign document specific text file is assigned.
So each time i have to modify find change GREP property that is also repetetive of work. Is there any way to get find change information should be extract from external text file.
Many Tanks in advance

In the FindChangeByList script, you could customize the function myFindFile(myFilePath) {...} as to search the FindChangeList text file in the document location rather than the script location. That's an example. The question is: given a document, where will you have the corresponding FindChangeList?

Use AppleScript or Automator (or both) to get Mail and add to a text file?

Hello all,
I'm sorry if this is a duplicate of a well-known topic, I tried searching and couldn't see anything.
I'm behind a proxy at work that blocks any kind of webmail access, but I'd like to be able to check my email while on a break or something.
I had the idea that I could use Automator or Applescript to check my mail, get the new messages and add the text to a textfile that I could host on my personal webserver that I use for family stuff.
I've tried an automator workflow that seems to work while in Automator, but when I save it as an application, it won't even start Mail to check.
I also thought of just leaving mail running, and have a rule that starts a script when new mail arrives, but I don't know enough about Applescript to do it.
I don't want to confuse anyone with the details of my convoluted ideas, so I'll leave it at that.
Is there a way to do this? I want mail to check the server, download the messages, new messages get their text appended to a text file that's stored in my webserver's directory (same computer) that I can access from the web, and have it repeat every 5 minutes or so.
If I've left out a detail, let me know, and if I'm just stupid and there's an easy way to do this... be kind.
Thanks!

It certainly is going in the right direction. I'm not all that versed in AppleScript, but it looks like that particular script is creating a new text file for every message processed.
I would like to either create a specific text file if it doesn't exist, or append the text to the end of the file if it does exist.
But like I said, definitely heading in the right direction!

Parse large (2GB) text file

Hi all,
I would like your expert tips on efficient ways (speed and memory considerations) for parsing large text files (~2GB) in Java.
Specifically, the text files in hand contain mobility traces that I need to process. Traces have a predefined format, and each trace is given on a new line in the text file.
To obtain the attribues of each trace i use java.util.regex.Pattern and java.util.regex.Matcher.
Thanks in advance,
Nick

Memory mapped files are faster when you need random access and you don't need to load all the data, however here it just add complexity you don't need IMHO.
I suspect most of the time is taken by the parser so if you customise your parser it could be faster. Here is a simple custom parser
public static void main(String... args) throws IOException {
    String template = "tr at %.1f \"$obj(1) pos 123.20 270.98 0.0 2.4\"%n";
    File file = new File("/tmp/deleteme.txt");
//        if(!file.exists()) {
        System.out.println(new Date()+": Writing to "+file);
        PrintWriter pw = new PrintWriter(file);
        for(int i=0;i<Integer.MAX_VALUE/template.length();i++)
            pw.printf(template, i/10.0);
        pw.close();
        System.out.println(new Date()+": ... finished writing to " + file + " length= " + file.length() / 1024 / 1024 + " MB.");
    long start = System.nanoTime();
    final BufferedReader br = new BufferedReader(new FileReader(file), 64 * 1024);
    for(String line;(line = br.readLine()) != null;) {
        int pos = 6;
        int end = line.indexOf(' ', pos);
        double time = Double.parseDouble(line.substring(pos, end));
        pos = line.indexOf('s', end+12)+2;
        end = line.indexOf(' ', pos+1);
        double x = Double.parseDouble(line.substring(pos, end));
        pos = end+1;
        end = line.indexOf(' ', pos+1);
        double y = Double.parseDouble(line.substring(pos, end));
        pos = end+1;
        end = line.indexOf(' ', pos+1);
        double z = Double.parseDouble(line.substring(pos, end));
        pos = end+1;
        end = line.indexOf('"', pos+1);
        double velocity = Double.parseDouble(line.substring(pos, end));
    br.close();
    long time = System.nanoTime() - start;
    System.out.printf(new Date()+": Took %,f sec to read %s%n", time / 1e9, file.toString());
{code}
prints

Using a scanner to parse a text file

Hi,
I'm running into some difficulties using a pattern for my scanner (java.util.Scanner). I need to scan a text file which consists of records. Each record has a keyword and a value (like property files):
Example:
FACILITY=TEST
LOT=1234567
DEVICE=abcdefgNormally, every record will be ended by a carriage return and line feed. So what I did was using a scanner with cr/lf as delimiter. That worked fine for most records but there are some records which span several lines (with cr/lf at the end of each line), e.g.:
MAP_XY.01.01=" Y-7 24/10 Y-6 24 22/17 15/7 Y-5 29/7 5 Y-4 32/22 20

BIN_COUNT.01.09=12345Using the following delimiter does not work
fileScanner.useDelimiter("\\s*=\\s*");because the result would be something like:
keyword: FACILITY     value: TEST
LOTkeyword: 1234567
DEVICE     value: abcdefgWhat I need is a pattern which also handles carriage return/line feed until a new keyword (like LOT for example) occurs.
The correct result should be:
keyword: FACILITY     value: TEST
keyword: LOT            value: 1234567
keyword: DEVICE     value: abcdefg
keyword: MAP_XY.01.01 value: " Y-7 24/10 Y-6 24 22/17 15/7 Y-5 29/7 5 Y-4 32/22 20...
{code}
I hope, I did explain clearly enough...
Any help would be appreciated.
Thanks and best regards

Any help would be appreciated.You have grouping and data in the groupings and you are attempting to parse it all at one go.
Won't work. (Might in a perfect world but not in this one.)
You need a parsers that do the following
1. Parser text file (stream) into records.
2. Parse records into data.
You can put both into one class or not.
Your record parser is going to be based roughly on the following scheme.
1. Find keyword,
2. Look up format defined for keyword
3. Attempt to read format found.
4. Error if format not found.
5. Else return the record found.
I say roughly because as noted above you need to know what the actual output looks like. It is possible to determine this if you have enough examples but it is a lot easier if you actually get the specification that tells you what it looks like.
I suspect, but don't know that the "format" in the above will consist of the following.
<word><text>
or
<word><text>
<space><text>
<space><text>
You could just create one format for the all but you will likely have record types that don't fit that and the earlier you detect errors the better.

Can I add specific text to Template via pop up text box on opening file?

In most word processors it is possible to create a template that asks you for specific text when you open it, so that you can have the letter three quarters written within the template, and only need to replace names, addresses, date and so on.
In Lotus WordPro for instance, before I even see the file, I have to fill in a dialogue box with the persons name, the subject of the letter, and four or five specifics unique to them. The WP then adds this info into the letter, and all I need do is to occasionally write a further full paragraph.
How do I do this in Pages? I can't seem to find anyway to do it at all. I have a suspicion I might need Apple Script, but I'm not sure how I can do that. I have a book of how to code, but I don't know where to store the macro, nor to write it yet - the book's just there if I need it.
I want to open the file, and then be asked one item at a time for the personalised answers to questions that occur in every report/letter.
Any ideas?
TIA
Mac

Thanks for your suggestions, Magnus, you really have had a good think for me - I appreciate that!
What I am doing is report writing in which 90% of the report is the same for everyone. Except the cover page with Name and Address details, and Report title; the initial section which is the same for everyone except for specifics such as amount to invest, reason for investment, term to invest over, things like that.
The end of the report is the recommendations section which is where I use freetext to create a bespoke solution - this cannot be automated.
Just automating the cover page and the intro section save me huge amounts of time which I can then use on research and fund analysis, leaving the principles of investment section pretty much the same for everyone, as here I'm describing the principle and theory.
After I created this Report Template my average report creation time went down from about 3 to 4 hours, to about 45 minutes. I guess the automation itself doesn't save as much time as the templating does, but it allows me to concentrate on the important bit and not worry if I have left something out - or in - that changes the overall thrust of the report.
I cannot load Lotus WorpPro on Parallels, nor on Virtual PC, so the lack of automation really is a pain here. I see it as a weakness of Apple products for business, as I am sure Microsoft do which is why they have dropped VBA support for Office 2008.
I have got NeoOffice as well as OpenOffice for Mac on my system, but really they aren't atable enough to use, and the formatting is pretty flaky. It certainly isn't completely consistent with Office itself.
So, I am left with the conclusion that progress only means a reduction in features!
But maybe I'm missing something?

How to retrieve specific data from a text file

Hi, everyone
For my project it is required that a parameter file is read at the beginning, in order for certain variables to be initialized with specific values that change with the user.
At the moment, the way it is done is the following: The values at a specified sequence in a text file are read and saved in an array and the elements of the array are retrieved according to their index.
The problem with this implementation is, that if for some reason the format of the file changes, e.g. we want to use a parameter file from a previous version of the program that has the values for the same variables but in a different order, the only way to have the right values for the parameters is to change everything accordingly, which is really time wasting.
Could someone suggest a different implementation that would make the reading of the different values independent from their order in the file, e.g. by scanning the file for specific strings and reading the value after the string?
Thank you very much.
P.S. I have attached a screenshot of the routine I am using now.
Solved!

Hi panagiov,
Find attached Folders.
Method 1: in this you can search for each variable separately. You can use "Config file vis" to get all keys(Variables) at once and then you can use for loop to get their values. Or you can access individual values as shown in this code.
Method 2: here you will get all data at once. You will get Variable and Data (2D array) You need to search variables as and when required.
I hope you will understand these methods.
Best of luck

How to parse data from a text file with no convenient delimiters?

I need to read data from a text file. This file contains one line of data with the repeating pattern "time 00 ADVar2: ___ Height: ____ time 01 ADVar2: ___ Height: ___ ..." I need LabView to parse out the "time" and "height" values, build an array with the values, and graph the correlation on an X&Y plot. Does Labview have an automated way to read to the input data file and parse out the correct values, even without convenient delimiters? Thank you.

You actually do have a convenient delimiter: "time". Thus, you can make an array using that as the delimiter. Only caveat is that the first array element will be empty. Then you can conveniently use the Scan From String function in a for-loop. Something like this:

How can i read all the lines from a text file in specific places and use the data ?

string[] lines = File.ReadAllLines(@"c:\wmiclasses\wmiclasses1.txt");
for (int i = 0; i < lines.Length; i++)
if (lines[i].StartsWith("ComboBox"))
And this is how the text file content look like:
ComboBox Name cmbxOption
Classes Win32_1394Controller
Classes Win32_1394ControllerDevice
ComboBox Name cmbxStorage
Classes Win32_LogicalFileSecuritySetting
Classes Win32_TapeDrive
What i need to do is some things:
1. Each time the line start with ComboBox then to get only the ComboBox name from the line for example cmbxOption.
Since i have already this ComboBoxes in my form1 designer i need to identify where the cmbxOption start and end and when the next ComboBox start cmbxStorage.
2. To get all the lines of the current ComboBox for example this lines belong to cmbxOption:
Classes Win32_1394Controller
Classes Win32_1394ControllerDevice
3. To create from each line a Key and Value for example from the line:
Classes Win32_1394Controller
Then the key will be Win32_1394Controller and the value will be only 1394Controller
Then the second line key Win32_1394ControllerDevice and value only 1394ControllerDevice
4. To add to the correct belonging ComboBox only the value 1394Controller.
5. To make that when i select in the ComboBox for example in cmbxOption the item 1394Controller it will act like i selected Win32_1394Controller.
For example in this event:
private void cmbxOption_SelectedIndexChanged(object sender, EventArgs e)
InsertInfo(cmbxOption.SelectedItem.ToString(), ref lstDisplayHardware, chkHardware.Checked);
In need that the SelectedItem will be Win32_1394Controller but the user will see in the cmbxOption only 1394Controller without the Win32_
This is the start of the method InsertInfo
private void InsertInfo(string Key, ref ListView lst, bool DontInsertNull)
That's why i need that the Key will be Win32_1394Controller but i want that the user will see in the ComboBox only 1394Controller without the Win32_

Hello,
Here is a running start on getting specific lines in the case lines starting with ComboBox. I took your data and placed it into a text file named TextFile1.txt in the bin\debug folder. Code below was done in
a console app.

using System.IO;
using System.Linq;
namespace ConsoleApplication1
internal class Program
private static void Main(string[] args)
var result =
from T in File.ReadAllLines(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "TextFile1.txt"))
.Select((line, index) => new { Line = line, Index = index })
.Where((s) => s.Line.StartsWith("ComboBox"))
select T
).ToList();
if (result.Count > 0)
foreach (var item in result)
Console.WriteLine("Line: {0} Data: {1}", item.Index, item.Line);
Console.ReadLine();

How can I use Automator to extract specific Data from a text file?

I have several hundred text files that contain a bunch of information. I only need six values from each file and ideally I need them as columns in an excel file.
How can I use Automator to extract specific Data from the text files and either create a new text file or excel file with the info? I have looked all over but can't find a solution. If anyone could please help I would be eternally grateful!!! If there is another, better solution than automator, please let me know!
Example of File Contents:
Link Time =
DD/MMM/YYYY

bytes of DATA    memory (+    59 absolute )
1 875
bytes of XDATA   memory (+ 1 855 absolute )
90 783

You may try the following AppleScript script. It will ask you to choose a root folder where to start searching for *.map files and then create a CSV file named "out.csv" on desktop which you may import to Excel.
set f to (choose folder with prompt "Choose the root folder to start searching")'s POSIX path
if f ends with "/" then set f to f's text 1 thru -2
do shell script "/usr/bin/perl -CSDA -w <<'EOF' - " & f's quoted form & " > ~/Desktop/out.csv

Having trouble reading specific lines from a text file and displaying them in a listbox

I am trying to read specific lines from all of the text files in a folder that are reports. When I run the application I get the information from the first text file and then it returns this error: "A first chance exception of type 'System.ArgumentOutOfRangeException'
occurred in mscorlib.dll"
Below is the code from that form.
Option Strict On
Option Infer Off
Option Explicit On
Public Class frmInventoryReport

lineNumber = intTemp
End Function
Public Function FileMatches(ByVal folderPath As String, ByVal filePattern As String, ByVal phrase As String) As Boolean
For Each fileName As String In IO.Directory.GetFiles(folderPath, filePattern)
If fileName.ToLower().Contains(phrase.ToLower()) Then
Return True
End If
Next
Return False
End Function

Sorry I'm just beginning coding and I'm still a noob. Any help is appreciated. Thank you!

Ok, so if I'm following this correctly you should be able to just loop through all of the files in that folder whose file name matches the pattern and then read the first 22 lines, recording only the first and the last.
Exactly how you store the animal data probably depends on how you are going to display it and what else you are going to do with it. Is there anything other than name and cage number that should be associated with each animal?
You might want to make a dataset with a datatable to describe the animal, or you might write a class, or you might just use something generic like a Tuple. Here's a simple class example:
Public Class Animal
Public Property Name As String
Public Property Cage As String
Public Overrides Function ToString() As String
Return String.Format("{0} - {1}", Name, Cage)
End Function
End Class
With that you can use a routine like the following to loop through all of the files and read each one:
Dim animals As New List(Of Animal)
Dim folderPath As String = "E:\Furry Friends Animal Shelter Solution\Furry Friends Animal Shelter\"
For Each filePath As String In System.IO.Directory.GetFiles(folderPath, "Report Q?.txt")
Using reader As New System.IO.StreamReader(filePath)
Dim lineIndex As Integer = 0
Dim currentAnimal As New Animal
While Not reader.EndOfStream
Dim line As String = reader.ReadLine
If lineIndex = 0 Then
currentAnimal.Name = line
ElseIf lineIndex = 22 Then
currentAnimal.Cage = line
Exit While
End If
lineIndex += 1
End While
animals.Add(currentAnimal)
End Using
Next
'do something to display the animals list
Then you might bind the animals list to a ListBox, or loop through the list and populate a ListView. If you decided to fill a datatable instead of making Animal instances, then you might bind the resulting table to a DataGridView.
There are lots of options depending on what you want and what all you need to do.

Program to read only specific words in each Line in a text file

Hi
I have a question
I need to write a program where the program must read only specific words in each line
I will give you an example...
PSAPPSRV.21201 1-42 13.35.54 238.360 Cur#1.HDEV RC=0 Dur=0.000 COM Stmt=SELECT VERSION FROM PSVERSION WHERE OBJECTTYPENAME = 'SYS'
PSAPPSRV.21201 1-43 13.35.54 0.040 Cur#2.HDEV RC=0 Dur=0.000 COM Stmt=SELECT STYLESHEETNAME FROM PSOPTIONS
These are two lines in my text file...now I need to read only the SQL statements present that is both SELECT statements.. Can you please suggest a method.......

My first reaction to the question is why would you want such thing, but may be I am unknown :)
Assuming you have the text as string, I mean
String str = "PSAPPSRV.21201 1-42 13.35.54 238.360 Cur#1.HDEV RC=0 Dur=0.000 COM Stmt=SELECT VERSION FROM PSVERSION WHERE OBJECTTYPENAME = \'SYS\'";you can obtain the sql statement using substring method like
String result = str.substring(str.indexOf("SELECT")); Again I assume there is no word SELECT preceding and the word SELECT is all caps.
