    Miva Empresa 5.23 Has Been Released

    Miva Empresa 5.23 Release Notes

    New Features

    New Built-in Functions

    slugify( data )

    Use this function to create friendly URLs. It takes characters that are forbidden in URIs and either converts them to a valid ASCII character or remove thems completely. It adds a hyphen (-) in place of all space characters. For example, the product "Padre Baseball Hat!" becomes "Padre-Baseball-Hat" which is now URI friendly.

    Parameters:
    • data - The string to convert


    Return Value:
    • The converted URI friendly string

    miva_splitstring( string, sep, output var, flags )

    Splits a string into chunks in an array, using the separator parameter as the point to split the string.

    Parameters:
    • string The input string
    • sep A single character that will be used to split the string into multiple elements
    • output var The array of elements
    • flags A comma separated list of any of the following:
      • trim removes extra space around the left and right sides of all elements
      • ltrim removes extra space around the left side of all elements
      • rtrim removes extra space around the right side of all elements
      • lower converts all elements to lowercase
      • upper converts all elements to uppercase
      • insensitive searches for sep input parameter using a case-insensitive search


    Return Value:
    • The number of elements in the output array

    fssymlink( source, destination )

    This function creates a symbolic link from a file in the data directory to the scripts directory (Available on UNIX file systems only).

    Parameters:
    • source source file fully qualified path in the data directory
    • destination destination file fully qualified path in the scripts directory


    Return Value:
    • 1 if success
    • 0 if fail

    sfsymlink( source, destination )

    This function creates a symbolic from a file in the scripts directory to the data directory (Available on UNIX file systems only).

    Parameters:
    • source source file fully qualified path in the scripts directory
    • destination destination file fully qualified path in the data directory


    Return Value:
    • 1 if success
    • 0 if fail

    New API Methods

    mvProgram_CharacterSetIsUTF8 Determines whether the current character set is set to UTF8

    Parameters:
    • mvProgram program: The current MivaVM


    Return Value:
    • 1 if the character set is UTF8
    • 0 otherwise

    mvProgram_GetCharacterSet Returns the current character set

    Parameters:
    • mvProgram program: The current MivaVM


    Return Value:
    • A null terminated string containing the current character set

    mvLinkBuffer_Allocate A wrapper method used to interact with the LinkBuffer class

    Parameters:
    • int first_block_size The size in bytes of the first block to be created
    • int grow_size The size in bytes of all subsequent blocks that are created


    Return Value:
    • Returns an mvLinkBuffer which is a pointer to the LinkBuffer class in memory

    mvLinkBuffer_Free A wrapper method used to delete a previously allocated LinkBuffer

    Parameters:
    • mvLinkBuffer linkbuffer A previously allocated mvLinkBuffer


    Return Value:
    • None

    mvLinkBuffer_Concat_String A wrapper method used to append a string to the end of the LinkBuffer string

    Parameters:
    • mvLinkBuffer linkbuffer A previously allocated mvLinkBuffer
    • const char *data The data string to add to the end of the LinkBuffer string
    • int data_length The length of the passed in data pointer


    Return Value:
    • None

    mvLinkBuffer_Concat_Char A wrapper method used to append a character to the end of the LinkBuffer string

    Parameters:
    • mvLinkBuffer linkbuffer A previously allocated mvLinkBuffer
    • char data A single character to add to the end of the LinkBuffer string


    Return Value:
    • None

    mvLinkBuffer_Concat_HexChar A wrapper method used to append a character in hex format to the end of the LinkBuffer string

    Parameters:
    • mvLinkBuffer linkbuffer A previously allocated mvLinkBuffer
    • unsigned char data A single character that will be converted to hex, then added to the end of the LinkBuffer string


    Return Value:
    • None

    mvLinkBuffer_Concat_Release A wrapper method used to get the value of all LinkBuffer blocks glued together. Using this method will clear out the data from the LinkBuffer memory and you are responsible for freeing it from memory.

    Parameters:
    • mvLinkBuffer linkbuffer A previously allocated mvLinkBuffer
    • int *data_length An output parameter stating the length of the returned data string
    • int *data_size An output parameter stating how many bytes are allocated for the returned data string
    • int headroom A value that ensures X number of extra bytes are available in the size of the returned data string (useful if you want to ensure there is enough room to null-terminate the string)


    Return Value:
    • (char * ) A null-terminated string of all the data blocks glued together

    mvLinkBuffer_Data A wrapper method used to get the value of all LinkBuffer blocks glued together. Using this method will not clear out the data from memory and you should not free this from memory.

    Parameters:
    • mvLinkBuffer linkbuffer A previously allocated mvLinkBuffer
    • int *data_length An output parameter stating the length of the returned data string


    Return Value:
    • (const char * ) A null-terminated string of all the data blocks glued together

    Store Morph Changes

    • &mvts:...; (outputs a token using the slugify function)

    Other Changes

    • Both the MivaScript compiler and virtual machine are now supported on MacOS X
    • Hexadecimal values are now allowed for numeric configuration settings, such as MvCONFIG_FLAGS_SECURITY and MvCONFIG_LOG_LEVEL

It adds a hyphen (-) in place of all space characters. For example, the product "Padre Baseball Hat!" becomes "Padre-Baseball-Hat" which is now URI friendly.
    Can we get some specifics on this please? Which characters are removed, which characters are converted, and what are they converted to?

      Hey Kent -

      In the 9.0004 LSK see this file:
      /features/uri/uri_ut.mv

      It has a function: URI_Slugify. The Engine version of this does the same replacement, just faster since it is at the engine level.

        From a look at the LSK source code, it appears that the slugify operation consists of the following steps:

        - Replace a number of international characters with alphanumeric substitutes; e.g. use upper-case A instead of the "A with a tilde on top" character (ASCII 195).

        - Replace all white-space characters with dashes.

        - Remove anything that's not an alphanumeric, dash, or underscore.
