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?

Re: Miva Empresa 5.23 Has Been Released

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.

[Kent Multer]

Re: Miva Empresa 5.23 Has Been Released

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.
