Detailed Description
+INTERNAL
+Function Documentation
+ +§ available_codepages()
+ +| MUTILS_API QStringList MUtils::available_codepages | +( | +const bool & | +noAliases = true | ) | ++ |
Retrieve a list of all available codepages.
+The function generates a list of all codepages that are available on the system. Each codepage name returned by this function may be passed to the QTextCodec::codecForName() function in order to obtain a corresponding QTextCodec object.
- Parameters
-
+
+
+noAliases If set to true, only distinct codepages are returned, i.e. any codepage aliases are discarded from the list; if set tofalse, the returned list may (and usually will) also contain codepage aliases.
+
- Returns
- If the function succeeds, it returns a QStringList holding the names of all codepages available on the system; otherwise it returns a default-constructed QStringList.
§ clean_file_name()
+ +| MUTILS_API QString MUtils::clean_file_name | +( | +const QString & | +name | ) | ++ |
Clean up a file name string.
+This function ensures that the given string is a valid file (or directory) name. It does so by replacing any illegal characters, i.e. any characters not allowed in file names (which explicitly includes directory separators). Furthermore, the function will trim/remove specific characters that are not allowed directly at the beginning or end of a file name. Finally, the function takes care or special "reserved" file names that are forbidden by the file system. You can use this function to convert user inputs into a valid file name.
+- Parameters
-
+
+
+list A read-only reference to the QString holding the original, potentially invalid file name.
+
- Returns
- The function returns a QString holding a valid file name. If, however, the input string was empty or contained only white-space characters, the returned sting can be empty.
§ clean_file_path()
+ +| MUTILS_API QString MUtils::clean_file_path | +( | +const QString & | +path | ) | ++ |
Clean up a file path string.
+This function ensures that the given string is a valid file (or directory) path. It does so by replacing any illegal characters, i.e. any characters not allowed in file paths. Directory separators are preserved, but they will be "canonicalized". Furthermore, in each path component, the function will trim/remove specific characters that are not allowed directly at the beginning or end of a path component. Finally, the function takes care or special "reserved" file names that are forbidden by the file system. You can use this function to convert user inputs into a valid file path.
+- Parameters
-
+
+
+list A read-only reference to the QString holding the original, potentially invalid file path.
+
- Returns
- The function returns a QString holding a valid file path. If, however, the input string was empty or contained only white-space characters, the returned sting can be empty.
§ init_process()
+ +| MUTILS_API void MUtils::init_process | +( | +QProcess & | +process, | +
| + | + | const QString & | +wokringDir, | +
| + | + | const bool | +bReplaceTempDir = true, |
+
| + | + | const QStringList *const | +extraPaths = NULL |
+
| + | ) | ++ |
Initialize a given QProcess object.
+This function prepares a given QProcess object for sub-process creation. It does so by setting up combined stdout and stderr redirection for the sub-process, cleaning up the sub-process' environment variables, as well as setting up the sub-process' working directory. Optionally, the Temp directory for the sub-process can be set to the application-specific Temp directory, which is achieved by overwriting the corresponding environment variables (e.g. TMP and TEMP). Furthermore, additional paths can be added to the PATH environment variable of the sub-process.
- Parameters
-
+
+
+process A reference to the QProcess object to be initialized. The QProcess object must be initialized before calling the QProcess::start()method.process A read-only reference to a QString holding the path of the working directory for the sub-process. bReplaceTempDir If set to true, the Temp directory for the sub-process is set to the application-specific Temp directory; if set tofalse, the default Temp directory is retained.extraPaths A read-only pointer to a QStringList object containing additional paths that will be added (prepended) to the sub-process' PATHenvironment variable. This parameter can beNULL, in which case no additional paths are added.
+
§ make_temp_file()
+ +| MUTILS_API QString MUtils::make_temp_file | +( | +const QString & | +basePath, | +
| + | + | const QString & | +extension, | +
| + | + | const bool | +placeholder = false |
+
| + | ) | ++ |
Generates a temporary file name.
+The function generates a file name that contains a random component and that is guaranteed to not exist yet. The generated file name follows a "<basedir>/<random>.<ext>" pattern. This is useful (not only) for creating temporary files.
- Parameters
-
+
+
+basePath Specifies the "base" directory where the temporary file is supposed to be created. This must be a valid existing directory. extension Specifies the desired file extensions of the temporary file. Do not include a leading dot ( .) character.placeholder If set to true, the function creates an empty "placeholder" file under the returned file name; if set tofalse, it does not.
+
- Returns
- If the function succeeds, it returns a QString holding the full path of the temporary file; otherwise it returns a default-constructed QString.
§ make_unique_file()
+ +| MUTILS_API QString MUtils::make_unique_file | +( | +const QString & | +basePath, | +
| + | + | const QString & | +baseName, | +
| + | + | const QString & | +extension, | +
| + | + | const bool | +fancy = false |
+
| + | ) | ++ |
Generates a unique file name.
+The function generates a unique file name in the specified directory. The function guarantees that the returned file name does not exist yet. If necessary, a counter will be included in the file name in order to ensure its uniqueness.
+- Parameters
-
+
+
+basePath Specifies the "base" directory where the unique file is supposed to be created. This must be a valid existing directory. baseName Specifies the desired "base" file name of the unique file. Do not include a file extension. extension Specifies the desired file extensions of the unique file. Do not include a leading dot ( .) character.fancy If set to true, the unique file name is generated according to the"<basedir>/<basename> (N).<ext>"pattern; if set tofalse, it is generated according to the"<basedir>/<basename>.XXXX.<ext>"pattern. Also, if set totrue, a counter is only included in the file name, if the file name without counter already exists; if set tofalse, a counter is always included. Finally, if set totrue, the counter starts at 2 and is printed in decimal format; if set tofalse, the counter starts at 0 and is printed in zero-padded hexadecimal format.
+
- Returns
- If the function succeeds, it returns a QString holding the full path of the unique file; otherwise it returns a default-constructed QString.
§ natural_string_sort()
+ +| MUTILS_API void MUtils::natural_string_sort | +( | +QStringList & | +list, | +
| + | + | const bool | +bIgnoreCase | +
| + | ) | ++ |
Sort a list of strings using "natural ordering" algorithm.
+This function implements a sort algorithm that orders alphanumeric strings in the way a human being would. See Natural Order String Comparison for details!
+- Parameters
-
+
+
+list A reference to the QStringList object to be sorted. The list will be sorted "in place". bIgnoreCase If set to true, the list will be sorted disregarding the character case, i.e. upper-case and lower-case characters (of the same letter) are treated the same; if set tofalse, the character case is taken into account.
+
§ next_rand_str()
+ +| MUTILS_API QString MUtils::next_rand_str | +( | +const bool & | +bLong = false | ) | ++ |
Generates a random string.
+The random string is generated using the same PRNG as the next_rand_u64() function. The random bytes are converted to a hexadecimal string and, if necessary, zero-padded to a toal length of 16 or 32 characters. There is no 0x-prefix included in the result.
- Parameters
-
+
+
+bLong If set to true, a "long" random string (32 characters) will be generated; if set tofalse, a "short" random string (16 characters) is generated.
+
- Returns
- The function returns a QString holding a random hexadecimal string
§ next_rand_u32()
+ +| MUTILS_API quint32 MUtils::next_rand_u32 | +( | +void | +) | ++ |
Generates a random unsigned 32-Bit value.
+The random value is created using a "strong" PRNG of the underlying system, if possible. Otherwise a fallback PRNG is used. It is not required or useful to call srand() or qsrand() prior to using this function. If necessary, the seeding of the PRNG happen automatically on the first call.
- Returns
- The function returns a random unsigned 32-Bit value.
§ next_rand_u64()
+ +| MUTILS_API quint64 MUtils::next_rand_u64 | +( | +void | +) | ++ |
Generates a random unsigned 64-Bit value.
+The random value is created using a "strong" PRNG of the underlying system, if possible. Otherwise a fallback PRNG is used. It is not required or useful to call srand() or qsrand() prior to using this function. If necessary, the seeding of the PRNG happen automatically on the first call.
- Returns
- The function returns a random unsigned 64-Bit value.
§ parity()
+ +| MUTILS_API bool MUtils::parity | +( | +quint32 | +value | ) | ++ |

+- Parameters
-
+
+
+value The 32-Bit unsigned value from which the parity is to be computed.
+
- Returns

| + | + | quint32 & | +value | +
| + | ) | ++ |
Parse regular expression results.
+This function tries to parses the result (capture) of a regular expression as an unsigned 32-Bit value. The given regular expression must contain at least one capture. Only the first capture is considered, additional captures are ignored.
+- Parameters
-
+
+
+regexp A read-only reference to the QRegExp object whose result (capture) will be parsed. This QRegExp must already have been successfully matched against the respective input string, e.g. via QRegExp::indexIn(), prior to calling this function.value A reference to a variable of type quint32, where the unsigned 32-Bit representation of the result will be stored. The contents of this variable are undefined, if the function failed.
+
- Returns
- The function returns
true, if the regular expression's capture could be parsed successfully; it returnsfalse, if the capture contains an invalid string or if there are insufficient captures in given the QRegExp object.
§ regexp_parse_uint32() [2/2]
+ +| MUTILS_API bool MUtils::regexp_parse_uint32 | +( | +const QRegExp & | +regexp, | +
| + | + | quint32 * | +values, | +
| + | + | const size_t & | +count | +
| + | ) | ++ |
Parse regular expression results.
+This function tries to parses the results (captures) of a regular expression as unsigned 32-Bit values. The given regular expression must contain at least count captures. Only the first count captures are considered, additional captures are ignored.
- Parameters
-

This QRegExp must already have been successfully matched against the respective input string, e.g. via QRegExp::indexIn(), prior to calling this function.value A pointer to an array of type quint32, where the unsigned 32-Bit representations of the results will be stored (then-th result is stored atvalue[n-1]). The array must be at leastcountelements in length. The contents of this array are undefined, if the function failed.count Specifies the number of results (captures) in the given QRegExp object. The function tries to parse the first countcaptures and ignores any additional captures that may exist. This parameter also determines the required (minimum) length of thevaluearray.
+
- Returns
- The function returns
true, if all of the regular expression's captures could be parsed successfully; it returnsfalse, if any of the captures contain an invalid string or if there are insufficient captures in given the QRegExp object.
§ remove_directory()
+ +| MUTILS_API bool MUtils::remove_directory | +( | +const QString & | +folderPath, | +
| + | + | const bool & | +recursive | +
| + | ) | ++ |
Recursively deletes the specified directory.
+The function deletes the specified directory. In recursive mode, the directory will be removed including all of its files and sub-directories. Files are deleted using the remove_file() function.
- Parameters
-
+
+
+folderPath The path to the directory to be deleted. This should be a full path. recursive If set to truethe function removes all files and sub-directories in the specified directory; if set tofalse, the function will not try to delete any files or sub-directories, which means that it will fail on non-empty directories.
+
- Returns
- The function returns
true, if the directory was deleted successfully or if the directory doesn't exist; it returnsfalse, if the directory could not be deleted.
§ remove_file()
+ +| MUTILS_API bool MUtils::remove_file | +( | +const QString & | +fileName | ) | ++ |
Deletes the specified file.
+The function deletes the specified file, even if it has the "read only" flag set. If the file is currently locked (e.g. by another process), the function retries multiple times to delete the file before it fails.
+- Parameters
-
+
+
+fileName The path to the file to be deleted. This should be a full path.
+
- Returns
- The function returns
true, if the file was deleted successfully or if the file doesn't exist; it returnsfalse, if the file could not be deleted.
§ temp_folder()
+ +| MUTILS_API const QString& MUtils::temp_folder | +( | +void | +) | ++ |
Rerieves the full path of the application's Temp folder.
+The application's Temp folder is a unique application-specific folder, intended to store any temporary files that the application may need. It will be created when this function is called for the first time (lazy initialization); subsequent calls are guaranteed to return the same path. Usually the application's Temp folder will be created as a sub-folder of the system's global Temp folder, as indicated by the TMP or TEMP environment variables. However, it may be created at a different place (e.g. in the users Profile directory), if those environment variables don't point to a usable directory. In any case, this function makes sure that the application's Temp folder exists for the whole lifetime of the application and that it is writable. When the application terminates normally, the application's Temp folder and all files or sub-directories thereof will be removed automatically!
- Returns
- If the function succeeds, it returns a read-only reference to a QString holding the full path of the application's Temp folder; otherwise a read-only reference to a default-constructed QString is returned.
