Text Manipulation

Extensions that manipulate with text

Textify has a main goal of providing you with text extensions that allow you to perform various operations on a string, and they will be listed individually in this page to have a quick overview of what each function does.

Text tools

Text tools can be found in the TextTools class under the Textify.Global namespace. They make it easier for you to manipulate with strings.

Character width tools

The below tools allow you to get the width of a character.

GetCharWidth()

public static int GetCharWidth(int c)

This uses the Unicode width database that Textify maintains internally to be able to determine whether a character use one, two, or zero cells. Some of the characters are either assigned as ambiguous, are private use characters, or unassigned characters, and their handling can be controlled by the following properties:

public static bool UseTwoCellsForUnassignedChars { get; set; }
public static bool UseTwoCellsForAmbiguousChars { get; set; }
public static bool UseTwoCellsForPrivateChars { get; set; }

This is primarily used for console operations, and is a good start to implement console applications that support CJK, such as console applications that use Terminaux.

GetCharWidthType()

public static CharWidthType GetCharWidthType(int c)

This function allows you to easily get the character width type from a specified Unicode character codepoint. This will return one of the following types:

• Private

• NonPrinting

• Combining

• DoubleWidth

• Ambiguous

• Emoji

• Unassigned

Wrapped sentence tools

The following functions allow you to wrap a long string into a specified length, both character-wise and word-wise.

The below functions are also found in Terminaux, though they also employ VT sequence support to help process them. For console applications, it's better to use the Terminaux version.

GetWrappedSentences()

public static string[] GetWrappedSentences(this string text, int maximumLength)
public static string[] GetWrappedSentences(this string text, int maximumLength, int indentLength)

This function allows you to wrap a long string into a list of strings that represent resultant lines. These lines correspond wrapped sentences by a specified length, and only wraps by the amount of characters. In addition to that, you can also specify an indentation length for the first line of the wrapped sentence.

• Nitrocid wrapped into four characters with no indentation will result in the following lines:

  • Nitr

  • ocid

• Nitrocid wrapped into four characters with 2 characters indentation will result in the following lines:

  • Ni

  • troc

  • id

GetWrappedSentencesByWords()

public static string[] GetWrappedSentencesByWords(this string text, int maximumLength)
public static string[] GetWrappedSentencesByWords(this string text, int maximumLength, int indentLength)

This function allows you to wrap a long string into a list of strings that represent resultant lines. These lines correspond wrapped sentences by a specified length, but also takes words into account, like word processors, for readability. In addition to that, you can also specify an indentation length for the first line of the wrapped sentence.

• Nitrocid KS kernel sim wrapped into four characters with no indentation will result in the following lines:

  • Nitr

  • ocid

  • KS

  • kern

  • el

  • sim

• Nitrocid KS kernel sim wrapped into four characters with 2 characters indentation will result in the following lines:

  • Ni

  • troc

  • id

  • KS

  • kern

  • el

  • sim

Double quote tools

The following functions manipulate with the double quotation in the string.

SplitEncloseDoubleQuotes()

public static string[] SplitEncloseDoubleQuotes(this string target)
public static string[] SplitEncloseDoubleQuotes(this string target, char[]? partialQuoteSplitChars = null)
public static string[] SplitEncloseDoubleQuotes(this string target, char match = ' ', char[]? partialQuoteSplitChars = null)
public static string[] SplitEncloseDoubleQuotes(this string target, Func<char, bool> condition, char[]? partialQuoteSplitChars = null)

This function splits a string with either a new line, a specific character, or a character condition, with support for splitting with double quotation marks (single quote, double quote, or backticks), while releasing the quotation marks that surround the string.

The primary reason was that because we were uncomfortable with the usage of Microsoft.VisualBasic in C# applications as we were migrating to C# for Nitrocid KS in 2022.

• A string, First "Second Third" Fourth, will be split like this:

  • First

  • Second Third

  • Fourth

Partial quote split characters can also be specified, but you'll need to be aware of the implications when using it, so it's best not to specify unless you're dealing with a very specific string.

SplitEncloseDoubleQuotesNoRelease()

public static string[] SplitEncloseDoubleQuotesNoRelease(this string target)
public static string[] SplitEncloseDoubleQuotesNoRelease(this string target, char[]? partialQuoteSplitChars = null)
public static string[] SplitEncloseDoubleQuotesNoRelease(this string target, char match = ' ', char[]? partialQuoteSplitChars = null)
public static string[] SplitEncloseDoubleQuotesNoRelease(this string target, Func<char, bool> condition, char[]? partialQuoteSplitChars = null)

This function splits a string with either a new line, a specific character, or a character condition, with support for splitting with double quotation marks (single quote, double quote, or backticks), without releasing the quotation marks that surround the string.

The primary reason was that because we were uncomfortable with the usage of Microsoft.VisualBasic in C# applications as we were migrating to C# for Nitrocid KS in 2022.

A string, First "Second Third" Fourth, will be split like this:

• First

• "Second Third"

• Fourth

Partial quote split characters can also be specified, but you'll need to be aware of the implications when using it, so it's best not to specify unless you're dealing with a very specific string.

ReleaseDoubleQuotes()

public static string ReleaseDoubleQuotes(this string target)

This function allows you to remove surrounding double quotes from the beginning and the end of the string. For example, the following strings will be changed:

GetEnclosedDoubleQuotesType()

public static EnclosedDoubleQuotesType GetEnclosedDoubleQuotesType(this string target)

This function allows you to determine the type of the double quotation that is found in the beginning and the end of the string. The following strings will be processed this way:

• "Double quotes" -> EnclosedDoubleQuotesType.DoubleQuotes

• 'Single quotes' -> EnclosedDoubleQuotesType.SingleQuotes

• `Backticks` -> EnclosedDoubleQuotesType.Backticks

• Normal -> EnclosedDoubleQuotesType.None

New line tools

The following functions manipulate with the new lines in the string.

SplitNewLines()

public static string[] SplitNewLines(this string target, bool emptyStrings = true)

This function allows you to easily split the string by new lines. You can optionally exclude empty lines by setting emptyStrings to false. This is platform-agnostic so that you don't have to specify what kind of new line you're splitting with.

• A string that contains line breaking characters, such as "First\r\nSecond\r\nThird", will be split like this:

  • First

  • Second

  • Third

UnixifyNewLines()

public static string UnixifyNewLines(this string target)

This function allows you to normalize the new line characters to convert them to Unix-based newlines (LF). This supports common and uncommon new line characters, such as CR + LF for Windows, CR for Mac OS 9, and others. This conforms to the Unicode standards.

• "First\r\nSecond\r\nThird" -> "First\nSecond\nThird"

• "First\rSecond\rThird" -> "First\nSecond\nThird"

Starts, Ends, and Contains tools

The following functions allow you to perform different kinds of beginning, ending, and substring detection in the string.

StartsWithAnyOf() and StartsWithAllOf()

public static bool StartsWithAnyOf(this string target, string[] values)
public static bool StartsWithAllOf(this string source, string[] values)
public static bool StartsWithAnyOf(this string target, char[] values)
public static bool StartsWithAllOf(this string source, char[] values)

This checks the string for a list of prefixes in the OR and the AND logical condition, respectively.

• StartsWithAnyOf() checks to see if any of the prefixes is found within the beginning of the string.

  • For example, this string "pre_rel-01-Servicing" returns true if any of "pre_" and "rel_" prefixes match.

• StartsWithAllOf() checks to see if all of the prefixes is found within the beginning of the string.

  • For example, this string "dotnet-hostfxr-8.0" returns true if all of "dotnet-" and "dotnet-hostfxr-" prefixes match, but returns false if one of the prefixes don't match, such as "dotnet-runtime-8.0".

EndsWithAnyOf() and EndsWithAllOf()

public static bool EndsWithAnyOf(this string target, string[] values)
public static bool EndsWithAllOf(this string source, string[] values)

This checks the string for a list of suffixes in the OR and the AND logical condition, respectively.

• EndsWithAnyOf() checks to see if any of the suffixes is found within the ending of the string.

  • For example, this string "Release-5.0-OOB" returns true if either the "-OOB" or the "-RTM" suffixes match.

• EndsWithAllOf() checks to see if all of the suffixes is found within the ending of the string.

  • For example, this string "Release-5.0-OOB" returns true if both the "-OOB" and the "-5.0-OOB" suffixes match, but returns false if one of the suffixes doesn't match, for example, "Release-4.6-OOB".

ContainsAnyOf() and ContainsAllOf()

public static bool ContainsAnyOf(this string source, string[] targets)
public static bool ContainsAllOf(this string source, string[] targets)
public static bool ContainsAnyOf(this string source, char[] targets)
public static bool ContainsAllOf(this string source, char[] targets)

This checks the string for a list of substrings in the OR and the AND logical condition, respectively.

• ContainsAnyOf() checks to see if any of the substrings is found within the string.

  • For example, this string "Branch-Prod-5.0" returns true if either the "Prod" or the "Staging" substrings match.

• ContainsAllOf() checks to see if all of the substrings is found within the string.

  • For example, this string "Branch-Prod-5.0" returns true if both the "Prod" and the "Branch" substrings match, but returns false if one of the substrings doesn't match, for example, "Branch-Staging-5.0".

AddPrefix() and AddSuffix()

public static string AddPrefix(this string text, string prefix, bool check = true)
public static string AddSuffix(this string text, string suffix, bool check = true)

These functions allow you to add either a prefix or a suffix to the string, respectively. This makes the task easier for you by automatically checking to see if the string already starts with a prefix or ends with a suffix.

• Prefixes

  • Adding prefixes with checking: Hello with str as prefix becomes strHello, and strHello with str as prefix becomes strHello.

  • Adding prefixes without checking: Hello with str as prefix becomes strHello, and strHello with str as prefix becomes strstrHello.

• Suffixes

  • Adding suffixes with checking:

If you want to turn automatic checking off, you can set the check argument value to false.

RemovePrefix() and RemoveSuffix()

public static string RemovePrefix(this string text, string prefix)
public static string RemoveSuffix(this string text, string suffix)

These functions allow you to remove either a prefix or a suffix to the string, respectively. This operation checks to see if the string already starts with a prefix or ends with a suffix.

VerifyPrefix() and VerifySuffix()

public static bool VerifyPrefix(this string text, string prefix, StringComparison comparison = StringComparison.CurrentCulture)
public static bool VerifySuffix(this string text, string suffix, StringComparison comparison = StringComparison.CurrentCulture)

These functions allow you to verify a prefix and a suffix within a string by comparing the following:

• Prefix at the beginning of the string

• Suffix at the end of the string

Currently, this comparison is case-sensitive according to your current culture settings determined by your operating system. However, the comparison argument lets you control case-sensitivity and culture-specific settings. For instance, you can make use of OrdinalIgnoreCase to verify the prefix or the suffix ordinally without checking for case sensitivity.

Encoding tools
