Load Again Command

Ring 1.12 comes with the Load Again command

Using this command we can load the Ring source file which contains constants more than one time.

This is useful when using Ring source files for translations through global constants.

Example:

The next function is part from a project which support Arabic and English languages

The files english.ring and arabic.ring contains constants for translation

One of these files is loaded in the start of the program

Loading the same file again using the (Load) command is not possible

Because the (Load) command load the same source file only for the first time and ignore next times.

So we have to use the (Load Again) command.

Where we can use these files again during the runtime as in the next code

func setLang nLanguage
        if C_ENV_DEFAULT_LANG = nLanguage
                return
        ok
        C_ENV_DEFAULT_LANG = nLanguage
        # Change the language
                switch nLanguage
                        on C_TRANSLATION_ENGLISH
                                load again "translation/english.ring"
                        on C_TRANSLATION_ARABIC
                                load again "translation/arabic.ring"
                off

ring_state_filetokens() function

Using the ring_state_filetokens() function we can get all the tokens in the ring source code file.

C_FILENAME      = "test_tokens.ring"
C_WIDTH         = 12

# write the file
        write(C_FILENAME,'
                        see "Hello, World!"
                        ? 3*2+3
                        Name = "Ring"
                        ? Name
')

# Token Type
        C_KEYWORD       = 0
        C_OPERATOR      = 1
        C_LITERAL       = 2
        C_NUMBER        = 3
        C_IDENTIFIER    = 4
        C_ENDLINE       = 5

# Keywords List
aKEYWORDS = ["IF","TO","OR","AND","NOT","FOR","NEW","FUNC",
"FROM","NEXT","LOAD","ELSE","SEE","WHILE","OK","CLASS","RETURN","BUT",
"END","GIVE","BYE","EXIT","TRY","CATCH","DONE","SWITCH","ON","OTHER","OFF",
"IN","LOOP","PACKAGE","IMPORT","PRIVATE","STEP","DO","AGAIN","CALL","ELSEIF",

"CHANGERINGKEYWORD","CHANGERINGOPERATOR","LOADSYNTAX"]

pState = ring_state_new()
aList = ring_state_filetokens(pState,C_FILENAME)
PrintTokens(aList)
ring_state_delete(pState)

func PrintTokens aList
        for aToken in aList
                switch aToken[1]
                on C_KEYWORD
                        ? Width("Keyword",C_WIDTH) + ": "  + aKeywords[0+aToken[2]]
                on C_OPERATOR
                        ? Width("Operator",C_WIDTH)  + ": " + aToken[2]
                on C_LITERAL
                        ? Width("Literal",C_WIDTH)  + ": " + aToken[2]
                on C_NUMBER
                        ? Width("Number",C_WIDTH)  + ": " + aToken[2]
                on C_IDENTIFIER
                        ? Width("Identifier",C_WIDTH)  + ": " + aToken[2]
                on C_ENDLINE
                        ? "EndLine"
                off
        next

func Width cText,nWidth
        return cText+copy(" ",nWidth-len(cText))

Output:

EndLine
Keyword     : SEE
Literal     : Hello, World!
EndLine
Operator    : ?
Number      : 3
Operator    : *
Number      : 2
Operator    : +
Number      : 3
EndLine
Identifier  : name
Operator    : =
Literal     : Ring
EndLine
Operator    : ?
Identifier  : name
EndLine

Generate Embedded Ring Object File

We can generate embedded object file (C source code) from the source code file (*.ring) using -geo option

Command:

ring test.ring -geo

This command will generate at least three files

test.c
ringappcode.c
ringappcode.h

More files could be generated based on the project size

The generated files will pass the byte code to Ring VM to be executed
