A vector of strings with line numbers and file names.

Definition at line 52 of file FileUtility.h.

Function Documentation

ROSE_UTIL_API std::string Rose::StringUtility::convertToLowerCase

(

const std::string &

inputString

)

Convert to lower case.

Returns a new string by converting each of the input characters to lower case with tolower.

ROSE_UTIL_API std::string Rose::StringUtility::fixLineTermination

(

const std::string &

input

)

Normalizes line termination.

Changes ASCII-based line termination conventions used by various operating systems into the LF (line-feed) termination used by Multics, Unix and Unix-like systems (GNU/Linux, Mac OS X, FreeBSD, AIX, Xenix, etc.), BeOS, Amiga, RISC OS and others. Any occurrance of CR+LF, LF+CR, or CR by itself (in that order of left-to-right matching) is replaced by a single LF character.

ROSE_UTIL_API std::string Rose::StringUtility::prefixLines	(	const std::string &	lines,
		const std::string &	prefix,
		bool	prefixAtFront = true,
		bool	prefixAtBack = false
	)

Insert a prefix string before every line.

This function breaks the lines string into individual lines, inserts the prefix string at the beginning of each line, then concatenates the lines together into a return value. If prefixAtFront is true (the default) then the prefix is added to the first line of lines, otherwise the first line is unchanged. An empty lines string is considered to be a single line. If prefixAtBack is false (the default) then the prefix is not appended to the lines string if lines ends with a linefeed.

ROSE_UTIL_API std::string Rose::StringUtility::leftJustify	(	const std::string &	input,
		size_t	width,
		char	fill = ' '
	)

Left justify a string to specified width.

The given string is either truncated or extended to make it the specified number of characters. New fill characters are added to the end of the string if necessary.

ROSE_UTIL_API std::string Rose::StringUtility::rightJustify	(	const std::string &	input,
		size_t	width,
		char	fill = ' '
	)

Right justify a string to specified width.

The given string is either truncated or extended to make it the specified number of characters. New fill characters are added to the beginning of the string if necessary.

ROSE_UTIL_API std::string Rose::StringUtility::centerJustify	(	const std::string &	input,
		size_t	width,
		char	fill = ' '
	)

Center a string in a field.

The given string is either truncated or extended to make it the specified number of characters. New fill characters are added to the beginning and end of the string if necessary.

ROSE_UTIL_API std::string Rose::StringUtility::makeOneLine	(	const std::string &	s,
		std::string	replacement = " "
	)

Converts a multi-line string to a single line.

This function converts a multi-line string to a single line by replacing line-feeds and carriage-returns (and their surrounding white space) with a user-supplied replacement string (that defaults to a single space). Line termination (and it's surrounding white space) that appears at the front or back of the input string is removed without replacing it.

See roseTests/utilTests/stringTests.C for lots of examples.

A new string is returned.

ROSE_UTIL_API std::string Rose::StringUtility::trim	(	const std::string &	str,
		const std::string &	strip = " \t\r\n",
		bool	at_beginning = true,
		bool	at_end = true
	)

Trims white space from the beginning and end of a string.

Caller may specify the characters to strip and whether the stripping occurs at the begining, the end, or both.

ROSE_UTIL_API std::string Rose::StringUtility::untab	(	const std::string &	str,
		size_t	tabstops = 8,
		size_t	firstcol = 0
	)

Expand horizontal tab characters.

ROSE_UTIL_API std::string Rose::StringUtility::removeRedundantSubstrings

(

const std::string &

)

Remove redundant and blank lines.

Splits the input string into substrings according to listToString, sorts the substrings and removes duplicates and lines that are empty (a line of only horizontal white space is not considered to be empty), then concatenates the substrings in their sorted order into the return value using listToString, inserting extra white space at the beginning of all but the first line.

The original implementation had a bug (ROSE-304) that caused the first substring to be removed from the return value even if it was non-empty and unique. This happened when it was not followed by a line-feed.

ROSE_UTIL_API std::string Rose::StringUtility::removeAnsiEscapes

(

const std::string &

)

Remove ANSI escape characters.

Currently handles only the "Control Sequence Introducer" commands, but these are the most common and most useful commands anyway since they include such things as cursor movement, erasing, scrolling, colors, and other graphic renditions.

ROSE_UTIL_API std::string Rose::StringUtility::encode_base64	(	const std::vector< uint8_t > &	data,
		bool	do_pad = true
	)

Convert binary data to base-64.

The base64 number system uses the characters A-Z, a-z, 0-9, +, and / (in that order). The returned string does not include linefeeds. If do_pad is true then '=' characters may appear at the end to make the total length a multiple of four.

ROSE_UTIL_API std::string Rose::StringUtility::encode_base64	(	const uint8_t *	data,
		size_t	nbytes,
		bool	do_padd = true
	)

Convert binary data to base-64.

The base64 number system uses the characters A-Z, a-z, 0-9, +, and / (in that order). The returned string does not include linefeeds. If do_pad is true then '=' characters may appear at the end to make the total length a multiple of four.

ROSE_UTIL_API std::vector<uint8_t> Rose::StringUtility::decode_base64

(

const std::string &

encoded

)

Convert base-64 to binary.

ROSE_UTIL_API unsigned long Rose::StringUtility::generate_checksum

(

std::string

s

)

Compute a checkshum.

This function returns a unique checksum from the mangled name used it provides a simple means to obtain a unique value for any C++ declaration. At a later date was should use the MD5 Checksum implementation (but we can do that later).

The declaration is the same under One-time Definition Rule (ODR) if and only if the checksum values for each declaration are the same.

ROSE_UTIL_API std::string Rose::StringUtility::indentMultilineString	(	const std::string &	inputString,
		int	statementColumnNumber
	)

Formatting support for generated code strings.

ROSE_UTIL_API void Rose::StringUtility::add_to_reason_string	(	std::string &	result,
		bool	isset,
		bool	do_pad,
		const std::string &	abbr,
		const std::string &	full
	)

Append an abbreviation or full name to a string.

ROSE_UTIL_API std::string Rose::StringUtility::appendAsmComment	(	const std::string &	s,
		const std::string &	comment
	)

Append an assembly comment to a string.

Assembly comments are surrounded by "<" and ">" characters. If the string already ends with an assembly comment, then the specified comment is inserted before the final ">" and separated from the previous comment with a comma. Assembly comments are usually used for things like printing a decimal representation of a hexadecimal value, etc.

Example: after executing these statements:

std::string s = "0xff";
s = appendAsmComment(s, "255");
s = appendAsmComment(s, "-1");

The variable "s" will contain "0xff<255,-1>"

template<typename T >

std::string Rose::StringUtility::plural	(	T	n,
		const std::string &	plural_phrase,
		const std::string &	singular_phrase = ""
	)

Helpful way to print singular or plural words.

 size_t n = ...;
 std::cout <<"received " <<plural(n, "values") <<"\n";
@encode

 Output for various values of <em>n</em> will be:

@code
 received 0 values
 received 1 value
 received 2 values

This function uses a handful of grade-school rules and common exceptions for converting the supplied plural word to a singular word when necessary. If these are not enough, then the singular form can be supplied as the third argument.

std::cout <<"graph contains " <<plural(nverts, "vertices", "vertex") <<"\n";

std::string Rose::StringUtility::demangledName

(

std::string

)

Compute demangled version of mangled name.

Runs the c++filt command on the input string and returns the result. If c++filt cannot be run then it prints an error to standard error and another to standard output. The pipes opened to communicate with the c++filt subcommand might not be closed if there's an error.

ROSE_UTIL_API std::string Rose::StringUtility::htmlEscape

(

const std::string &

)

Escapes HTML special characters.

Replaces "<", ">", and "&" with HTML character names and returns the result.

ROSE_UTIL_API std::string Rose::StringUtility::cEscape	(	const std::string &	,
		char	context = '"'
	)

Escapes characters that are special to C/C++.

Replaces special characters in the input so that it is suitable for the contents of a C string literal (if context is a double quote character) or the contents of a C character constant (if context is a single quote). That is, things like double quotes, line-feeds, tabs, non-printables, etc. are replace by their C backslash escaped versions. Returns the resulting string.

Note that if the first argument is a string then the context defaults to string literals, and if the first argument is a single character then the context defaults to character literals. Although this is usually what one wants, it's possible to change the context in both situations.

Referenced by Rose::CommandLine::SuffixMultiplierParser< uint64_t >::parse(), Rose::CommandLine::IntervalParser< AddressInterval >::parse(), and Rose::BinaryAnalysis::VxcoreParser::Exception::toString().

ROSE_UTIL_API std::string Rose::StringUtility::cEscape	(	char	,
		char	context = '\''
	)

Escapes characters that are special to C/C++.

Replaces special characters in the input so that it is suitable for the contents of a C string literal (if context is a double quote character) or the contents of a C character constant (if context is a single quote). That is, things like double quotes, line-feeds, tabs, non-printables, etc. are replace by their C backslash escaped versions. Returns the resulting string.

Note that if the first argument is a string then the context defaults to string literals, and if the first argument is a single character then the context defaults to character literals. Although this is usually what one wants, it's possible to change the context in both situations.

ROSE_UTIL_API std::string Rose::StringUtility::cUnescape

(

const std::string &

)

Unescapes C++ string literals.

When given a C++ string literals content, the part between the enclosing quotes, this function will look for escape sequences, parse them, and replace them in the return value with the actual characters they represent. For instance, passing in std::string{"hello\\nworld\\00hidden"} that contains 20 characters including two backslashes, the function replaces the first backslash+"n" pair with a line feed, and the second backslash+"0"+"0" with a NUL to result in std::string{"hello\nworld\0hidden"} (18 characters including the LF and NUL). Unicode escapes are not supported and will be left escaped in the return value.

(

const std::string &

)

Escapes characters that are special to the Bourne shell.

Assumes that the context is outside of any quoting and possibly adds quotes.

ROSE_UTIL_API std::string Rose::StringUtility::yamlEscape

(

const std::string &

)

Escapes characters that are special to YAML strings.

Assumes that the context is outside of any quoting and possibly adds quotes.

ROSE_UTIL_API std::string Rose::StringUtility::csvEscape

(

const std::string &

)

Escapes characters that are special in CSV tables.

Assumes that the context is outside of any quoting and possib9 adds quotes. See RFC 4180 for details.

ROSE_UTIL_API std::string Rose::StringUtility::escapeNewLineCharaters

(

const std::string &

)

Escapes line feeds and double quotes.

Scans the input string character by character and replaces line-feed characters with a backslash followed by the letter "l" and replaces double quotes by a backslash followed by a double qoute.

ROSE_UTIL_API std::string Rose::StringUtility::numberToString

(

ROSE_UTIL_API std::vector<std::string> Rose::StringUtility::split	(	const std::string &	separator,
		const std::string &	str,
		size_t	maxparts = UNLIMITED,
		bool	trim_white_space = false
	)

Splits strings into parts.

Find all non-overlapping occurrences the specified separator string by greedily scanning from left to right in the input string, str. The input string is then logically chopped into parts at each separator position and the parts are assembled into the return value. Only up to maxparts-1 occurrences of the separator string are found, and any remaining occurrences are not treated specially. For instance, if maxparts is two then at most one separator is found and at most two substrings are returned. Separators at positions that would result in empty substrings being returned are not treated specially–empty substrings can be returned. This occurs when a separator is found at the beginning or end of a string or two separators are adjacent. The C++ library already has other functions for removing empty strings from a list. If trim_white_space is true then white space is removed from the beginning and end of each returned substring and resulting empty substrings are not removed from the return value. The first few arguments are in the same order as for Perl's "split" operator.

		const std::string &	separator = ",",
		const std::string &	finalIntro = "and"
	)

Join strings as if they were English prose.

This is useful when generating documentation strings.

If the input is empty, the output is the empty string. I.e., () => ""

If the input is one phrase, the output is that phrase. E.g., ("foo") => "foo"

If the input is two phrases, the output will be those two phrases separated by "and" (the finalIntro). E.g., ("foo", "bar") => "foo and bar"

If the input is three or more phrases, they will be separated from one another by commas (the separator) and the last item will also be introduced with "and" (the finalIntro). E.g., ("foo", "bar", "baz") => "foo, bar, and baz"

No transformations are performed on the input phrases. Space characters are inserted after each separator and finalIntro. A space is also inserted before the finalIntro when the input is two phrases.

ROSE_UTIL_API std::string Rose::StringUtility::listToString	(	const std::list< int > &	,
		bool	separateStrings = false
	)

Generate a string from a list of integers.

The return value is the concatenation of substrings. Each substring is formed by converting the corresponding integer from the list into a string via numberToString and then adding a single space character and an optional line feed. The line feeds are added only if separateStrings is true.

ROSE_UTIL_API std::string Rose::StringUtility::listToString	(	const std::list< std::string > &	,
		bool	separateStrings = false

ROSE_UTIL_API std::list<std::string> Rose::StringUtility::stringToList

(

const std::string &

)

Split a string into substrings at line feeds.

Splits the input string into substrings at the linefeed characters to construct a list, then removes empty strings from the list.

The original implementation (pre-2016) had a bug (ROSE-304) that caused the last substring to not be returned if it was not followed by a linefeed. That implementation was also slow for large inputs (ROSE-305). Both of these are now fixed since stringToList is now implemented in terms of split.

ROSE_UTIL_API void Rose::StringUtility::splitStringIntoStrings	(	const std::string &	inputString,
		char	separator,
		std::vector< std::string > &	stringList
	)

Splits string into substring based on a separator character.

Empty strings are removed from the result, which is returned in the stringList argument. The return argument is cleared before the splitting begins.

ROSE_UTIL_API unsigned Rose::StringUtility::hexadecimalToInt

)

Convert an ASCII hexadecimal character to an integer.

Converts the characters 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f, A, B, C, D, E, and F into their hexadecimal integer equivalents. Returns zero if the input character is not in this set.

template<class Container , class Stringifier >

std::vector<std::string> Rose::StringUtility::toStrings	(	const Container &	numbers,
		const Stringifier &	stringifier = numberToString
	)

Converts a bunch of numbers to strings.

This is convenient when one has a container of numbers and wants to call join to turn it into a single string. For instance, here's how to convert a set of integers to a comma-separated list:

using namespace Rose::StringUtility;
std::set<int> numbers = ...;
std::string s = join(", ", toStrings(numbers));

Here's how to convert a vector of addresses to space-separated hexadecimal values:

using namespace Rose::StringUtility;
std::vector<rose_addr_t> addresses = ...;
std::string s = join(" ", toStrings(addresses, addrToString));

Here's how one could surround each address with angle brackets:

using namespace Rose::StringUtility;
struct AngleSurround {
    std::string operator()(rose_addr_t addr) {
       return "<" + addrToString(addr) + ">";

template<class IntegralType >

std::enable_if<std::is_integral<IntegralType>::value, Sawyer::Result<IntegralType, std::string> >::type Rose::StringUtility::toNumber

(

const std::string &

s

)

Safely convert a string to a number using C++ style syntax.

The input string must parse as a integer without leading white space and without trailing characters. For signed integer types, the integer may be immediately preceded by a minus ("-") or plus ("+") sign. The integer part may be preceded by a radix indicator: "0x" for hexadecimal or "0b" for binary. Octal and other radices are not supported. Digits may be separated from one another (or from the radix specifier) by a single underscore, as in "0b_0001_0010_0011_0100_0101_0110_0111_1000".

The IntegralType must be a signed or unsigned integer type of any width. The uint8_t and int8_t types are also accepted although they're aliases for unsigned char and signed char .

If a syntax error occurs, or if the magnitude of the value is too large to be represented by the specified IntegralType, then an error message is returned. The text of the message begins with either "syntax error:" or "overflow error:".

	)

Create a file.

Creates a new file, truncating any existing file with the same name, and writes the string outputString into the file. The name of the file is constructed by concatenating directoryName and fileNameString without any intervening component separator (e.g., no "/").

If the file cannot be created then this function silently fails (or aborts if ROSE is compiled in debug mode).

ROSE_UTIL_API std::string Rose::StringUtility::readFile

(

ROSE_UTIL_API FileWithLineNumbers Rose::StringUtility::readFileWithPos

(

const std::string &

fileName

)

Reads an entire text file.

Opens the specified file, reads its contents line by line into a vector of strings with location information, closes the file, and returns the vector. The file names in the returned value are absolute names. The strings in the return value have their final line-feeds removed.

If the file cannot be opened then an std::string error message is thrown. The message reads "File not found" regardless of the actual error condition.

ROSE_UTIL_API void Rose::StringUtility::homeDir

Returns the last component of a path in a filesystem.

Removes the "path" part of a "filename" (if there is one) and returns just the file name.

Terms are loosely defined and not likely to work for non-POSIX systems; consider using boost::filesystem instead.

ROSE_UTIL_API std::string Rose::StringUtility::getPathFromFileName

(

const std::string &

fileNameWithPath

)

Returns all but the last component of a path in a filesystem.

This function removes the filename from the combined path and filename if it includes a path and returns only the path. Make it safe to input a filename without a path name (return the filename).

Terms are loosely defined and this function possibly doesn't work for non-POSIX file systems; consider using boost::filesystem instead.

ROSE_UTIL_API std::string Rose::StringUtility::stripFileSuffixFromFileName

(

const std::string &

fileNameWithSuffix

Get the file name without the ".suffix".

Terms are loosely defined and it's not clear what happens for inputs like ".", ".foo", "..", ".foo.bar", "/.", etc. Consider using boost::filesystem instead.

ROSE_UTIL_API std::string Rose::StringUtility::getAbsolutePathFromRelativePath	(	const std::string &	relativePath,

	)

Get the absolute path from the relative path.

Terms are loosely defined and this function is not likely to work on non-POSIX systems. Consider using boost::filesystem instead.

ROSE_UTIL_API std::string Rose::StringUtility::fileNameSuffix

(

const std::string &

fileName

)

Get the file name suffix (extension) without the leading dot.

Filename could be either base name or name with full path. If no dot is found in the input fileName, the function just returns the original fileName.

Terms are loosely defined and this function is not likely to work correctly in some situations, such as when the "." is not in the last component of the file name. Consider using boost::filesystem instead.

ROSE_UTIL_API std::list<std::string> Rose::StringUtility::findfile	(	std::string	patternString,
		std::string	pathString
	)

Find file names non-recursively.

Scans the directory named pathString and returns a list of files in that directory which have patternString as a substring of their name. Note that patternString is not a glob or regular expression. The return value strings are formed by concatenating the pathString and the file name with an intervening slash.

This function does not work for non-POSIX systems. Consider using boost::filesystem instead, which has a directory iterator that works for non-POSIX systems also.

ROSE_UTIL_API FileNameClassification Rose::StringUtility::classifyFileName	(	const std::string &	fileName,

ROSE_UTIL_API int Rose::StringUtility::directoryDistance	(	const std::string &	left,
		const std::string &	right
	)

Edit distance between two directory names.

Essentially the edit distance without substituion in directory name tokens between two directories. Returns the "distance" between left and right. The distance is defined as the number of cd's that only move up or down one directory that it would take to move from the directory of the filename to the directory that was given by appPath. This is intended as a heuristic to gage whether or not one believes that the left is related to the right directory. Examples:

Between /a/b/c/file.h and /a/b/d/e/ the distance is 3 because one must cd ..; cd d; cd e

ROSE_UTIL_API std::vector<std::string> Rose::StringUtility::readWordsInFile

(

std::string

filename

)

Reads words from a file.

Opens the specified file for reading and reads all words from the file using std::istream operator>> into std::string. If the file cannot be opened then an error message is printed to standard output (not error) and the program exits with status 1.

bool Rose::StringUtility::popen_wrapper	(	const std::string &	command,
		std::vector< std::string > &	result
	)

Simple wrapper for Unix popen command.

If there is a failure (cannot create pipes, command not found, command terminated abnormally, input buffer too small, etc), then an error is printed to standard error (with or without line termination) and false is returned. When an error occurs the pipes that were opened to communicate with the subcommand might not be closed.

std::ostream& Rose::StringUtility::operator<< ( std::ostream &  os, const StringWithLineNumber &  s  )

inline

Prints a StringWithLineNumber.

ROSE_UTIL_API std::string Rose::StringUtility::toString	(	const FileWithLineNumbers &	strings,
		const std::string &	filename = "<unknown>",
		int	line = 1
	)

Generate C preprocessor #line directives.

Given a vector of strings with source location information, print those strings with intervening C preprocessor #line directives. For strings that have no source location, use the specified filename argument as the name of the file. The physicalLine is the line number to assume for the first line of output (the return value). The #line directives are not emitted into the return value when they're not needed (e.g., two strings are at successive line numbers of the same source file) or if ROSE has been configured to not emit #line directivies (i.e., the SKIP_HASH_LINE_NUMBER_DECLARATIONS_IN_GENERATED_FILES preprocessor symbol is defined). The strings should not have trailing linefeeds or else the output will contain extra blank lines.

FileWithLineNumbers& Rose::StringUtility::operator+= ( FileWithLineNumbers &  a, const FileWithLineNumbers &  b  )

inline

Append strings with source location information to vector of such.

Modifies a by appending those strings from b.

FileWithLineNumbers Rose::StringUtility::operator+ ( const FileWithLineNumbers &  a, const FileWithLineNumbers &  b  )

inline

Concatenate vectors of strings with source location.

Returns a new vector of strings with location information by concatenating vector a with b.

FileWithLineNumbers& Rose::StringUtility::operator<< ( FileWithLineNumbers &  f, const std::string &  str  )

inline

Append string to vector of strings with location information.

Appends str to the last string in the vector of strings with location information. If the vector is empty then a new element is created.

The new code is marked as either generated (empty file name) or not generated (non-empty name) based on whether the vector was initially empty or whether the final element of the vector was generated. Adding a string to an empty vector makes it always be a generated string; adding it to a non-empty vector makes it generated or not generated depending on whether the last element of the vector is generated or not generated.

The string str should not include line termination. (see toString).
