Separating Syllables into an array or list Unity C#

Im trying to seperate each syllable of an english word/name into a list. The code I have is counting the syllables perfectly which I also need, but I cannot figure out how to seperate each syllable from the words given.
Im using an input field but for now the example word is my name.
im very new to programming so please keep that in mind.
preferred example output would be something like {"joh", "nat", "hon"}
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class SyllableSeperator : MonoBehaviour
{
string word = "johnathon";
private void Start()
{
SyllableCount(word);
}
public static int SyllableCount(string word)
{
word = word.ToLower().Trim();
List<string> wordList = new List<string>();
bool lastWasVowel = false;
string vowels = "aeiouy";
int count = 0;
foreach (char c in word)
{
if (vowels.Contains(c))
{
if (!lastWasVowel)
{
count++;
lastWasVowel = true;
}
}
else
{
lastWasVowel = false;
}
}
if((word.EndsWith("e") || (word.EndsWith("es") || word.EndsWith("ed"))) && !word.EndsWith("le"))
{
count--;
}
return count;
}
}
what i have tried just does not work at all so I figured I wouldn't post that code.
Again please keep in mind that I am brand new to Unity and programming in general. Someone may have already asked how to do this but the code was too advanced for me.

Assuming you are checking the syllable by going through each character, you can make a temporary string and keep adding characters to the string.
Once you determine that string is good enough to be a syllable, add it to the list.
Like so:
public static int GetSyllableCount(string word, out List<string> syllableList)
{
word = word.ToLower().Trim();
List<string> syllableList = new List<string>();
bool lastWasVowel = false;
string vowels = "aeiouy";
StringBuilder currSyllable = new StringBuilder();
foreach (char c in word)
{
if (vowels.Contains(c))
{
if (!lastWasVowel)
{
lastWasVowel = true;
// Finish this syllable and add to the list
syllableList.Add(currSyllable.ToString());
currSyllable.Clear();
}
}
else
{
lastWasVowel = false;
}
// Add this character to the current syllable
currSyllable.Append(c);
}
if((word.EndsWith("e") || (word.EndsWith("es") || word.EndsWith("ed"))) && !word.EndsWith("le"))
{
// Remove the last syllable?
syllableList.Remove(syllableList.Count - 1);
}
return syllableList.Count;
}
The out parm modifer allows you to output another value.

parsing functions from text file without third party

I’ve been struggling wrapping my head around parsers and lexers, which I’m not even sure is the best way to tackle my challenge. I don’t want to use any third party libraries because of the unnecessary overhead, project size, and possible license issues.
Also there won’t be any arithmetic’s, loops, while’s, for’s or foreach’s
It’s a very simple parser that adds or instantiates objects from a text file.
For instance,
buildings.addWithMaterials([buildable:mansion], {{[materials: brick], [materials: wood]}, {[materials: wood], [materials: brick]}});
Parsing this text would add a Mansion made of two pieces of brick and wood to the buildings Collection.
The object buildable contains the properties Name which in this case is Mansion
and some building components which in this case are the materials Brick and Wood.
Any tip/direction to search for doing this?
I've looked and searched within stackoverflow, most entries I've stumbled upon refer to third parties
like Sprache and more.
If I missed an article, :/ sorry, please point it out to me
Thanks and kind regards, Nick

Providing all of the items in your script are in the same format, you can use something like this to parse it:
public static class ScriptParser
{
public static void Parse(string filename)
{
string[] script = null;
using (StreamReader reader = File.OpenText(filename))
{
// read the whole file, remove all line breaks and split
// by semicolons to get individual commands
script = reader.ReadToEnd().Replace("\r", string.Empty.Replace("\n", string.Empty)).Split(';');
}
foreach (string command in script)
HandleCommand(command);
}
// as arguments seem to be grouped you can't just split
// by commas so this will get the arguments recursively
private static object[] ParseArgs(string argsString)
{
int startPos = 0;
int depth = 0;
List<object> args = new List<object>();
Action<int> addArg = pos =>
{
string arg = argsString.Substring(startPos, pos - startPos).Trim();
if (arg.StartsWith("{") && arg.EndsWith("}"))
{
arg = arg.Substring(1, arg.Length - 2);
args.Add(ParseArgs(arg));
}
else
{
args.Add(arg);
}
}
for (int i = 0; i < argsString.Length; i++)
{
switch (argsString[i])
{
case ',':
if (depth == 0)
{
addArg(i);
startPos = i + 1;
}
break;
case '{':
// increase depth of parsing so that commas
// within braces are ignored
depth++;
break;
case '}':
// decrease depth when exiting braces
depth--;
break;
}
}
// as there is no final comma
addArg(argsString.Length);
return args.ToArray();
}
private static void HandleCommand(string commandString)
{
Command command = new Command();
string prefix = commandString.Substring(0, commandString.IndexOf("("));
command.Collection = prefix.Split('.')[0];
command.Action = prefix.Split('.')[1];
string commandArgs = commandString.Substring(commandString.IndexOf("("));
commandArgs = commandArgs.Substring(1, commandArgs.Length - 2);
command.Args = ParseArgs(commandArgs);
command.Execute();
}
private class Command
{
public string Collection;
public string Action;
public object[] Args;
public void Execute()
{
// need to handle any expected commands
if (Collection == "buildings")
{
if (Action == "addWithMaterials")
{
buildings.AddWithMaterials((string)Args[0], (object[])Args[1]);
}
}
}
}
//Eg.
public static BuildingCollection buildings = new BuildingCollection();
public class BuildingCollection
{
public void AddWithMaterials(string building, object[] materials)
{
Building building = new Building();
foreach (object[] materialsPart in materials)
// more stuff for you to work out
// you will need to match the strings to material classes
}
}
}
Usage:
ScriptParser.Parse("scriptfile.txt");
Note: This lacks error handling, which you will definitely want when parsing a file as it could contain anything.

Counting/sorting characters in a text file

I am trying to write a program that reads a text file, sorts it by character, and keeps track of how many times each character appears in the document. This is what I have so far.
class Program
{
static void Main(string[] args)
{
CharFrequency[] Charfreq = new CharFrequency[128];
try
{
string line;
System.IO.StreamReader file = new System.IO.StreamReader(#"C:\Users\User\Documents\Visual Studio 2013\Projects\Array_Project\wap.txt");
while ((line = file.ReadLine()) != null)
{
int ch = file.Read();
if (Charfreq.Contains(ch))
{
}
}
file.Close();
Console.ReadLine();
}
catch (Exception e)
{
Console.WriteLine("The process failed: {0}", e.ToString());
}
}
}
My question is, what should go in the if statement here?
I also have a Charfrequency class, which I'll include here in case it is helpful/necessary that I include it (and yes, it is necessary that I use an array versus a list or arraylist).
public class CharFrequency
{
private char m_character;
private long m_count;
public CharFrequency(char ch)
{
Character = ch;
Count = 0;
}
public CharFrequency(char ch, long charCount)
{
Character = ch;
Count = charCount;
}
public char Character
{
set
{
m_character = value;
}
get
{
return m_character;
}
}
public long Count
{
get
{
return m_count;
}
set
{
if (value < 0)
value = 0;
m_count = value;
}
}
public void Increment()
{
m_count++;
}
public override bool Equals(object obj)
{
bool equal = false;
CharFrequency cf = new CharFrequency('\0', 0);
cf = (CharFrequency)obj;
if (this.Character == cf.Character)
equal = true;
return equal;
}
public override int GetHashCode()
{
return m_character.GetHashCode();
}
public override string ToString()
{
String s = String.Format("'{0}' ({1}) = {2}", m_character, (byte)m_character, m_count);
return s;
}
}

Have a look at this post.
https://codereview.stackexchange.com/questions/63872/counting-the-number-of-character-occurrences
It uses LINQ to achieve your goal

You shouldn't use Contains
first you need to initialize your Charfreq array:
CharFrequency[] Charfreq = new CharFrequency[128];
for (int i = 0; i < Charferq.Length; i++)
{
Charfreq[i] = new CharFrequency((char)i);
}
try
then you can
int ch;
// -1 means that there are no more characters to read,
// otherwise ch is the char read
while ((ch = file.Read()) != -1)
{
CharFrequency cf = new CharFrequency((char)ch);
// This works because CharFrequency overloads the
// Equals method, and the Equals method checks only
// for the Character property of CharFrequency
int ix = Array.IndexOf(Charfreq, cf);
// if there is the "right" charfrequency
if (ix != -1)
{
Charfreq[ix].Increment();
}
}
Note that this isn't the way I would write the program. This is the minimum changes needed to make your program working.
As a sidenote, this program will count the "frequency" of ASCII characters (characters with code <= 127)
CharFrequency cf = new CharFrequency('\0', 0);
cf = (CharFrequency)obj;
And this is an useless initialization:
CharFrequency cf = (CharFrequency)obj;
is enough, otherwise you are creating a CharFrequency just to discard it the line below.

A dictionary is well suited for a task like this. You didn't say which character set and encoding the file was in. So, because Unicode is so common, let's assume the Unicode character set and UTF-8 encoding. (After all, it is the default for .NET, Java, JavaScript, HTML, XML,….) If that's not the case then read the file using the applicable encoding and fix your code because you currently are using UTF-8 in your StreamReader.
Next comes iterating across the "characters". And then incrementing the count for a "character" in the dictionary as it is seen in the text.
Unicode does have a few complex features. One is combining characters, where a base character can be overlaid with diacritics etc. Users view such combinations as one "character", or, as Unicode calls them, graphemes. Thankfully, .NET gives is the StringInfo class that iterates over them as a "text element."
So, if you think about it, using an array would be quite difficult. You'd have to build your own dictionary on top of your array.
The example below uses a Dictionary and is runnable using a LINQPad script. After it creates the dictionary, it orders and dumps it with a nice display.
var path = Path.GetTempFileName();
// Get some text we know is encoded in UTF-8 to simplify the code below
// and contains combining codepoints as a matter of example.
using (var web = new WebClient())
{
web.DownloadFile("http://superuser.com/questions/52671/which-unicode-characters-do-smilies-like-%D9%A9-%CC%AE%CC%AE%CC%83-%CC%83%DB%B6-consist-of", path);
}
// since the question asks to analyze a file
var content = File.ReadAllText(path, Encoding.UTF8);
var frequency = new Dictionary<String, int>();
var itor = System.Globalization.StringInfo.GetTextElementEnumerator(content);
while (itor.MoveNext())
{
var element = (String)itor.Current;
if (!frequency.ContainsKey(element))
{
frequency.Add(element, 0);
}
frequency[element]++;
}
var histogram = frequency
.OrderByDescending(f => f.Value)
// jazz it up with the list of codepoints in each text element
.Select(pair =>
{
var bytes = Encoding.UTF32.GetBytes(pair.Key);
var codepoints = new UInt32[bytes.Length/4];
Buffer.BlockCopy(bytes, 0, codepoints, 0, bytes.Length);
return new {
Count = pair.Value,
textElement = pair.Key,
codepoints = codepoints.Select(cp => String.Format("U+{0:X4}", cp) ) };
});
histogram.Dump(); // For use in LINQPad

Does anyone know of an open-source library that allows you to parse and read .csv files in C#?

Here, written by yours truly to use generic collections and iterator blocks. It supports double-quote enclosed text fields (including ones that span mulitple lines) using the double-escaped convention (so "" inside a quoted field reads as single quote character). It does not support:
Single-quote enclosed text
\ -escaped quoted text
alternate delimiters (won't yet work on pipe or tab delimited fields)
Unquoted text fields that begin with a quote
But all of those would be easy enough to add if you need them. I haven't benchmarked it anywhere (I'd love to see some results), but performance should be very good - better than anything that's .Split() based anyway.
Now on GitHub
Update: felt like adding single-quote enclosed text support. It's a simple change, but I typed it right into the reply window so it's untested. Use the revision link at the bottom if you'd prefer the old (tested) code.
public static class CSV

Take a look at A Fast CSV Reader on CodeProject.

The last time this question was asked, here's the answer I gave:
If you're just trying to read a CSV file with C#, the easiest thing is to use the Microsoft.VisualBasic.FileIO.TextFieldParser class. It's actually built into the .NET Framework, instead of being a third-party extension.
Yes, it is in Microsoft.VisualBasic.dll, but that doesn't mean you can't use it from C# (or any other CLR language).
Here's an example of usage, taken from the MSDN documentation:
Using MyReader As New _
Microsoft.VisualBasic.FileIO.TextFieldParser("C:\testfile.txt")
MyReader.TextFieldType = FileIO.FieldType.Delimited
MyReader.SetDelimiters(",")
Dim currentRow As String()
While Not MyReader.EndOfData
Try
currentRow = MyReader.ReadFields()
Dim currentField As String
For Each currentField In currentRow
MsgBox(currentField)
Next
Catch ex As Microsoft.VisualBasic.FileIO.MalformedLineException
MsgBox("Line " & ex.Message & _
"is not valid and will be skipped.")
End Try
End While
End Using
Again, this example is in VB.NET, but it would be trivial to translate it to C#.

I really like the FileHelpers library. It's fast, it's C# 100%, it's available for FREE, it's very flexible and easy to use.

I'm implementing Daniel Pryden's answer in C#, so it is easier to cut and paste and customize. I think this is the easiest method for parsing CSV files. Just add a reference and you are basically done.
Add the Microsoft.VisualBasic Reference to your project
Then here is sample code in C# from Joel's answer:
using (Microsoft.VisualBasic.FileIO.TextFieldParser MyReader = new
Microsoft.VisualBasic.FileIO.TextFieldParser(filename))
{
MyReader.TextFieldType = Microsoft.VisualBasic.FileIO.FieldType.Delimited;
MyReader.SetDelimiters(",");
while (!MyReader.EndOfData)
{
try
{
string[] fields = MyReader.ReadFields();
if (first)
{
first = false;
continue;
}
// This is how I treat my data, you'll need to throw this out.
//"Type" "Post Date" "Description" "Amount"
LineItem li = new LineItem();
li.date = DateTime.Parse(fields[1]);
li.description = fields[2];
li.Value = Convert.ToDecimal(fields[3]);
lineitems1.Add(li);
}
catch (Microsoft.VisualBasic.FileIO.MalformedLineException ex)
{
MessageBox.Show("Line " + ex.Message +
" is not valid and will be skipped.");
}
}
}

Besides parsing/reading, some libraries do other nice things like convert the parsed data into object for you.
Here is an example of using CsvHelper (a library I maintain) to read a CSV file into objects.
var csv = new CsvHelper( File.OpenRead( "file.csv" ) );
var myCustomObjectList = csv.Reader.GetRecords<MyCustomObject>();
By default, conventions are used for matching the headers/columns with the properties. You can change the behavior by changing the settings.
// Using attributes:
public class MyCustomObject
{
[CsvField( Name = "First Name" )]
public string StringProperty { get; set; }
[CsvField( Index = 0 )]
public int IntProperty { get; set; }
[CsvField( Ignore = true )]
public string ShouldIgnore { get; set; }
}
Sometimes you don't "own" the object you want to populate the data with. In this case you can use fluent class mapping.
// Fluent class mapping:
public sealed class MyCustomObjectMap : CsvClassMap<MyCustomObject>
{
public MyCustomObjectMap()
{
Map( m => m.StringProperty ).Name( "First Name" );
Map( m => m.IntProperty ).Index( 0 );
Map( m => m.ShouldIgnore ).Ignore();
}
}

You can use Microsoft.VisualBasic.FileIO.TextFieldParser
get below code example from above article
static void Main()
{
string csv_file_path=#"C:\Users\Administrator\Desktop\test.csv";
DataTable csvData = GetDataTabletFromCSVFile(csv_file_path);
Console.WriteLine("Rows count:" + csvData.Rows.Count);
Console.ReadLine();
}
private static DataTable GetDataTabletFromCSVFile(string csv_file_path)
{
DataTable csvData = new DataTable();
try
{
using(TextFieldParser csvReader = new TextFieldParser(csv_file_path))
{
csvReader.SetDelimiters(new string[] { "," });
csvReader.HasFieldsEnclosedInQuotes = true;
string[] colFields = csvReader.ReadFields();
foreach (string column in colFields)
{
DataColumn datecolumn = new DataColumn(column);
datecolumn.AllowDBNull = true;
csvData.Columns.Add(datecolumn);
}
while (!csvReader.EndOfData)
{
string[] fieldData = csvReader.ReadFields();
//Making empty value as null
for (int i = 0; i < fieldData.Length; i++)
{
if (fieldData[i] == "")
{
fieldData[i] = null;
}
}
csvData.Rows.Add(fieldData);
}
}
}
catch (Exception ex)
{
}
return csvData;
}

}
Sometimes you don't "own" the object you want to populate the data with. In this case you can use fluent class mapping.
// Fluent class mapping:
public sealed class MyCustomObjectMap : CsvClassMap<MyCustomObject>
{
public MyCustomObjectMap()
{
Map( m => m.StringProperty ).Name( "First Name" );
Map( m => m.IntProperty ).Index( 0 );
Map( m => m.ShouldIgnore ).Ignore();
}
}

You can use Microsoft.VisualBasic.FileIO.TextFieldParser
get below code example from above article
static void Main()
{
string csv_file_path=#"C:\Users\Administrator\Desktop\test.csv";
DataTable csvData = GetDataTabletFromCSVFile(csv_file_path);
Console.WriteLine("Rows count:" + csvData.Rows.Count);
Console.ReadLine();
}
private static DataTable GetDataTabletFromCSVFile(string csv_file_path)
{
DataTable csvData = new DataTable();
try
{
using(TextFieldParser csvReader = new TextFieldParser(csv_file_path))
{
csvReader.SetDelimiters(new string[] { "," });
csvReader.HasFieldsEnclosedInQuotes = true;
string[] colFields = csvReader.ReadFields();
foreach (string column in colFields)
{
DataColumn datecolumn = new DataColumn(column);
datecolumn.AllowDBNull = true;
csvData.Columns.Add(datecolumn);
}
while (!csvReader.EndOfData)
{
string[] fieldData = csvReader.ReadFields();
//Making empty value as null
for (int i = 0; i < fieldData.Length; i++)
{
if (fieldData[i] == "")
{
fieldData[i] = null;
}
}
csvData.Rows.Add(fieldData);
}
}
}
catch (Exception ex)
{
}
return csvData;
}
