1c string functions. New functions for working with strings
The String type is found in all programming languages. It is primitive, and in 1C there are many functions for working with it. In this article we will look in detail at various ways of working with string types in 1C 8.3 and 8.2 using examples.
Line
In order to convert a variable of any type into a string, there is a function of the same name “String()”. The input parameter will be the variable itself, the string representation of which must be obtained.
String(False) // returns "No"
String(12345) // returns "12,345"
String(CurrentDate()) //"07/21/2017 11:55:36″
It is possible to convert not only primitive types to a string, but also others, for example, elements of directories and documents.
SokrLP, SokrL, SokrP
The input parameters of these functions are a variable of string type. The functions remove insignificant characters (spaces, carriage returns, etc.): from the left and right sides, only from the left side, and only from the right, respectively.
Abbreviation(" Spaces will be removed on both sides ") // "Spaces will be removed on both sides"
Abbreviation(" Spaces on both sides will be removed ") // " Spaces on the left will be removed "
Abbreviation(" Spaces on both sides will be removed ") // " Spaces on the right will be removed"
Leo, Right, Medium
These functions allow you to trim part of a string. The "Left()" function will return the portion of a string from its left side of the specified length. The "Right()" function is similar, but crops from the right. The “Avg()” function allows you to specify the number of the character from which the line will be selected and its length.
Lev("String variable", 4) // returns "Str"
Right("String variable", 7) // returns "variable"
Medium("String variable", 2, 5) // returns "troco"
StrLength
The function determines the number of characters that are contained in a string variable.
StrLength("Word") // the result of execution will be the number 5
Find
The function makes it possible to search for part of a string in a string variable. The return value will be a number that shows the position of the beginning of the found string. If no match is found, zero is returned.
Please note that the search is case sensitive. If there is more than one occurrence of the search substring in the original string, the function will return the beginning of the first occurrence.
Find("one, two, one, two, three", "two") // the function will return the number 6
Empty line
Using this function allows you to determine whether a string is empty. Minor characters such as space, carriage return, and others are not taken into account.
EmptyString("Pupkin Vasily Ivanovich") // function will return the value False
EmptyString(" ") // function will return the value True
VReg, NReg, TReg
These functions are very useful when comparing and converting string variables. "Vreg()" will return the original string in uppercase, "HPreg()" in lowercase, and "TReg()" will format it so that the first character of each individual word is capitalized, and all subsequent characters are capitalized.
VReg("GENERAL DIRECTOR") // return value - "GENERAL DIRECTOR"
NReg(“CEO DIRECTOR”) // return value – “CEO”
TREG(“CEO DIRECTOR”) // return value – “General Director”
PageReplace
This function is analogous to replacement in text editors. It allows you to replace one character or set of characters with another in string variables.
StrReplace("red, white, yellow", ","", ";") // returns "red; white; yellow"
StrNumberLines
The function allows you to determine the number of lines separated by carriage returns in a text variable.
The loop in the example below will go through three rounds because the LineNumberRow function will return the value 3:
For ind = 1 by StrNumber of Strings ("Line1" + Symbols.PS + "Line2" + Symbols.PS + "Line3") Cycle
<тело цикла>
EndCycle;
StrGetString
This function works with multiline text in the same way as the previous one. It allows you to get a specific string from a text variable.
StrGetString("String1" + Characters.PS + "String2" + Characters.PS + "String3", 2) // return "String2"
PageNumberOccurrences
The function counts the number of occurrences of a character or substring in the search string.
StrNumberAttachments("a;b;c;d; ", ";") // function will return the number 4
Symbol and Symbol Code
These functions allow you to obtain a character by its code in the Unicode encoding, as well as determine this code by the character itself.
SymbolCode("A") // function will return the number 1,040
CharacterCode(1040) // function will return “A”
Common tasks when working with strings
Concatenating Strings
To combine several strings (to perform concatenation), it is enough to use the addition operator.
“Line 1″ + “Line 2″ //the result of adding two lines will be “Line 1 Line 2”
Type Conversion
In order to convert a type into a string, for example, a link to a directory element, a number, etc., it is enough to use the “String()” function. Functions like “ScrLP()” will also convert variables into a string, but immediately with cutting off insignificant characters.
String(1000) // returns "1,000"
Please note that when converting a number to a string, the program automatically added a space separating the thousand. In order to avoid this, you can use the following constructions:
StrReplace(String(1000),Characters.NPP,"") // returns "1000"
String(Format(1000,"HG=")) // returns "1000"
Quotes in a string
Quite often you will have to deal with the need to specify quotation marks in a string variable. This can be either the request text written in the configurator, or just a variable. To solve this problem, you just need to set two quotation marks.
Header = String("Horns and Hooves LLC - that's us!") // will return "Horns and Hooves LLC - that's us!"
Multi-line, line break
In order to create multi-line text, just add line breaks (Symbols.PS) to it.
MultilineText = “First Line” + Symbols.PS + “Second Line”
How to remove spaces
In order to remove spaces on the right or left, you can use the “ScrAP()” function (as well as “ScrL()” and “ScrP()”):
StringNoSpaces = Abbreviation(" Many letters ") // the function will return the value "Many letters"
If, after converting a number to a string, you need to remove non-breaking spaces, use the following construction:
StringNoSpaces = StrReplace(String(99999),Characters.NPP,"") // returns "99999"
Programmers also often use the following construction, which allows you to remove or replace with another character all spaces in a text variable:
StringNoSpaces = StrReplace("hello","") // returns "hello"
Comparing strings with each other
You can compare terms with the usual equal sign. The comparison is case sensitive.
"Hello" = "hello" // returns False
"Hello" = "Hello" // returns True
"Hello" = "Goodbye" // will return False
There are few mechanisms for working with strings in 1C queries. First, the lines can be added. Secondly, you can take a substring from a string. Thirdly, strings can be compared, including by pattern. That's probably all that can be done with strings.
String addition
To add rows in a query, the “+” operation is used. You can only add strings of limited length.
SELECT "Name: " + Counterparties. Name AS Column 1 FROM Directory. Counterparties AS Counterparties WHERE Counterparties. Link = &Link
Substring function
SUBSTRING(<Строка>, <НачальнаяПозиция>, <Длина>)
An analogue of the Environment() function from the object model. The Substring() function can be applied to string data and allows you to select a fragment <Строки> , starting with the character number <НачальнаяПозиция> (characters in a line are numbered starting from 1) and length <Длина> characters. The result of the function calculation has a variable-length string type, and the length will be considered unlimited if <Строка> has unlimited length and parameter <Длина> is not a constant or greater than 1024.
If the length of the string is less than specified in the second parameter, then the function will return an empty string.
Attention! Using the SUBSTRING() function to convert strings of unlimited length to strings of limited length is not recommended. Instead, it is better to use the cast operator EXPRESS().
Function Similar
If we need to make sure that a string attribute meets certain criteria, we compare it:
SELECT Counterparties. Name AS Column 1 FROM Directory. Counterparties AS Counterparties WHERE Counterparties. Name = "Gazprom"
But what if you need a more subtle comparison? Not just equality or inequality, but similarity to a certain pattern? This is exactly what the SIMILAR function was created for.
LIKE — Operator for checking a string for similarity to a pattern. Analogue of LIKE in SQL.
The SIMILAR operator allows you to compare the value of the expression specified to the left of it with the pattern string specified to the right. The value of the expression must be of type string. If the value of the expression matches the pattern, the result of the operator will be TRUE, otherwise it will be FALSE.
The following characters in the template string are service characters and have a meaning different from the string character:
- % (percent): a sequence containing any number of arbitrary characters;
- _ (underscore): one arbitrary character;
- […] (one or more characters in square brackets): any single character listed inside the square brackets. The enumeration may contain ranges, for example a-z, meaning an arbitrary character included in the range, including the ends of the range;
- [^...] (in square brackets a negation sign followed by one or more characters): any single character other than those listed following the negation sign.
Any other symbol means itself and does not carry any additional load. If one of the listed characters needs to be written as itself, then it must be preceded by<Спецсимвол>. Myself<Спецсимвол>(any suitable character) is defined in the same statement after the SPECIAL CHARACTER keyword.
Implemented in version 8.3.6.1977.
We have expanded the set of functions designed to work with strings. We did this in order to give you more advanced tools for parsing string data. The new functions will be convenient and useful in technological tasks of text analysis. In tasks related to parsing text that contains data in formatted form. This could be an analysis of some files received from the equipment, or, for example, an analysis of a technological log.
You could perform all the actions that perform new functions before. Using more or less complex algorithms written in a built-in language. Therefore, new functions do not give you any fundamentally new capabilities. However, they allow you to reduce the amount of code and make the code simpler and more understandable. In addition, they allow you to speed up the execution of actions. Because the functions implemented in the platform work, of course, faster than a similar algorithm written in a built-in language.
Formatting function StrTemplate()
This function substitutes parameters into a string. The need for such a conversion often arises, for example, when displaying warning messages. The syntax for this function is as follows:
StrTemplate(<Шаблон>, <Значение1-Значение10>)
<Шаблон>- this is the string into which you need to substitute the parameter representations.
<Значение1> , ... <Значение10>- these are parameters (maximum ten), the representations of which must be substituted into the string.
To indicate a specific place in the template where you want to perform the substitution, you need to use markers like %1, ... %10. The number of markers involved in the template and the number of parameters containing values must match.
For example, the result of executing such an operator:
there will be a line:
Data error on line 2 (Date type required)
Function for working with strings StrCompare()
This function compares two strings in a case-insensitive manner. For example, like this:
You could perform the same action earlier using the Value Comparison object:
However, using the new feature looks easier. And besides this, the function, unlike the Value Comparison object, works in both the thin client and the web client.
Functions for working with strings StrStartsWith(), StrEndsAt()
These functions determine whether a string begins with a specified substring or whether a string ends with a specified substring. The algorithm for these functions is not difficult to implement in an embedded language, but their presence allows you to write cleaner and more understandable code. And they work faster.
For example, they are convenient to use in the If statement:
Functions for working with strings StrDivide(), StrConnect()
These functions split a string into parts using a specified delimiter. Or vice versa, they combine several lines into one, inserting the selected separator between them. They are convenient for creating or analyzing logs and technological journals. For example, you can easily parse a technological log entry into parts suitable for further analysis:
Function for working with strings StrFind()
Instead of the old Find() function, we have implemented a new function that has additional capabilities:
- Search in different directions (from the beginning, from the end);
- Search from a specified position;
- Search for an occurrence with a specified number (second, third, etc.).
In fact, it duplicates the capabilities of the old function. This is done in order to maintain compatibility with modules compiled in older versions. It is recommended that you no longer use the old Find() function.
Below is an example using the new search capabilities. Reverse search is useful when you need the last part of a formalized string, such as the full file name in a URL. And searching from a specified position helps in cases where you need to search in a known fragment, and not in the entire line.
Rows in 1C 8.3 in the built-in language 1C represent values of a primitive type Line. Values of this type contain a Unicode string of arbitrary length. String type variables are a set of characters enclosed in quotes.
Example 1. Let's create a string variable with text.
StringVariable = "Hello world!";

This section will provide the main functions that allow you to change lines in 1c, or analyze the information contained in them.
StrLength
StrLength(<Строка>) . Returns the number of characters contained in the string passed as a parameter.
Example 2. Let's count the number of characters in the line “Hello world!”
String = "Hello world!"; NumberofCharacters = StrLength(String); Report(NumberCharacters);
The result of executing this code will be the display of the number of characters in the line: 11.
AbbrL
AbbrL(<Строка>)
. Trims non-significant characters to the left of the first significant character in the string.
Minor characters:
- space;
- non-breaking space;
- tabulation;
- carriage return;
- line translation;
- translation of the form (page).
Example 3. Remove all spaces from the left side of the line "world!" and add the line “Hello” to it.
String = Abbreviation("world!"); String = "Hello"+String; Report(String);
The result of executing this code will be the display of the line “Hello world!” on the screen.
Abbreviated

AbbrLP
AbbrLP(<Строка>)
. Trims non-significant characters to the right of the first significant character in the string, and also trims non-significant characters to the left of the first significant character in the string. This function is used more often than the previous two, as it is more universal.
Example 5. Remove insignificant characters on the left and right in the name of the counterparty.
Counterparty = Directories. Counterparties.Find By Details("TIN", "0777121211"); AccountObject = Account.GetObject(); CounterpartyObject.Name = AbbrLP(CounterpartyObject.Name); AccountObject.Write();
a lion
A lion(<Строка>, <ЧислоСимволов>)
. Gets the first characters of the string, the number of characters is specified in the parameter Number of Characters.
Example 6. Let in the structure Employee contain the first, last and patronymic names of the employee. Get a string with last name and initials.
NameInitial = Lev(Employee.Name, 1); Patronymic Initial = Leo(Employee. Patronymic, 1); FullName = Employee.LastName + " " + FirstName Initial + "." + Middle Initial + ".";
Right
Right(<Строка>, <ЧислоСимволов>) . Gets the last characters of a string, the number of characters specified in the parameter Number of Characters. If the specified number of characters exceeds the length of the string, then the entire string is returned.
Example 7. Let a date in the format “yyyymmdd” be written at the end of a string variable, get a string with the date and convert it to type date.
String = "Current date: 20170910"; StringDate = Rights(String, 8); Date = Date(StringDate);
Wednesday
Wednesday(<Строка>, <НачальныйНомер>, <ЧислоСимволов>) . Gets a substring from the string passed as a parameter Line, starting from the character whose number is specified in the parameter InitialNumber and the length passed into the parameter Number of Characters. The numbering of characters in a line starts from 1. If in the parameter InitialNumber a value less than or equal to zero is specified, then the parameter takes the value 1. If the parameter Number of Characters is not specified, then characters up to the end of the line are selected.
Example 8. Let the string variable starting from the ninth position contain the region code, you should get it and write it in a separate line.
String = "Region: 99 Moscow"; Region = Avg(String, 9, 2);
PageFind
StrFind(<Строка>, <ПодстрокаПоиска>, <НаправлениеПоиска>, <НачальнаяПозиция>, <НомерВхождения>) . Searches for a specified substring in a string, returning the position number of the first character of the found substring. Let's look at the parameters of this function:

The result of executing this code will be the display of the symbol code “!” - 33.
Empty line
Empty line(<Строка>) . Checks whether the string consists of only insignificant characters, that is, whether it is empty.
Example 15. Check whether a string consisting of three spaces is empty.
Empty = EmptyString(" "); Report(Empty);
The result of executing this code will be the display of the word “Yes” (a string expression of a logical value True).
PageReplace
StrReplace(<Строка>, <ПодстрокаПоиска>, <ПодстрокаЗамены>) . Finds all occurrences of the search substring in the source string and replaces it with the replacement substring.
Example 16. In the line “Hello World!” replace the word “Peace” with the word “Friends”.
String = StrReplace("Hello World!", "World", "Friends"); Report(String);
The result of executing this code will be the display of the line “Hello Friends!”
StrNumberLines
StrNumberRow(<Строка>) . Allows you to count the number of lines in a multiline string. To go to a new line in 1s 8, use the symbol PS(newline character).
Example 17. Determine the number of lines in the text:
"First line
Second line
Third line"
Number = StrNumberString("First line"+Characters.PS +"Second line"+Symbols.PS +"Third line"); Report(Number);
The result of executing this code will be the display of the number of lines in the text: 3
StrGetString
StrGetString(<Строка>, <НомерСтроки>) . Gets a line in a multiline string by its number. Line numbering starts from 1.
Example 18. Get the last line in the text:
"First line
Second line
Third line"
Text = "First line" + Symbols. PS + "Second line" + Symbols. PS + "Third line"; LastRow = StrGetRow(Text, StrNumberLines(Text)); Report(LastLine);
The result of executing this code will be the display of the line “Third Line”.
PageNumberOccurrences
StrNumberOccurrences(<Строка>, <ПодстрокаПоиска>) . Returns the number of occurrences of the specified substring in a string. The function is case sensitive.
Example 19. Determine how many times the letter “c” appears in the line “Lines in 1s 8.3 and 8.2”, regardless of its case.
Line = "Lines in 1s 8.3 and 8.2"; NumberOccurrences = StrNumberOccurrences(Vreg(String), "C"); Report(NumberOccurrences);
The result of executing this code will be the display of the number of occurrences: 2.
PageStartsWith
StrStartsWith(<Строка>, <СтрокаПоиска>) . Checks whether the string passed in the first parameter begins with the string in the second parameter.
Example 20. Determine whether the TIN of the selected counterparty begins with the number 1. Let in the variable Counterparty Counterparties.
TIN = Counterparty.TIN; StartsUNits = StrStartsWith(TIN, "1"); If Starts with units Then //Your code EndIf;
PageEndsOn
StrEndsWith(<Строка>, <СтрокаПоиска>) . Checks whether the string passed in the first parameter ends with the string in the second parameter.
Example 21. Determine whether the TIN of the selected counterparty ends with the number 2. Let in the variable Counterparty a reference to a directory element is stored Counterparties.
TIN = Counterparty.TIN; EndsWithTwo = StrEndsWith(TIN, "2"); If EndsInTwo Then //Your code EndIf;
PageSplit
StrDivide(<Строка>, <Разделитель>, <ВключатьПустые>) . Splits a string into parts using the specified delimiter characters and writes the resulting strings to an array. The first parameter stores the source string, the second contains the string containing the delimiter, and the third indicates whether empty strings should be written to the array (by default True).
Example 22. Let us have a string containing numbers separated by the symbol “;”, get an array of numbers from the string.
String = "1; 2; 3"; Array = StrDivide(String, ";"); For Count = 0 By Array.Quantity() - 1 Cycle Attempt Array[Count] = Number(AbbrLP(Array[Count])); Exception Array[Sch] = 0; EndAttemptsEndCycle;
As a result of execution, an array with numbers from 1 to 3 will be obtained.
PageConnect
StrConnect(<Строки>, <Разделитель>) . Converts the array of strings from the first parameter to a string containing all the elements of the array separated by the delimiter specified in the second parameter.
Example 23. Using the array of numbers from the previous example, get the original string.
For Account = 0 By Array.Quantity() - 1 Cycle Array[Act] = String(Array[Act]); EndCycle; Row = StrConnect(Array, "; ");
