TABLE OF CONTENTS MUIBuilder.library/--background-- MUIBuilder.library/MB_Open MUIBuilder.library/MB_Close MUIBuilder.library/MB_GetA MUIBuilder.library/MB_GetVarInfoA MUIBuilder.library/MB_GetNextCode MUIBuilder.library/MB_GetNextNotify MUIBuilder.library/--background-- The goal of the muibuilder library is, at this time, to provide some functions to help the writing of MUIBuilder external generators. These functions are described in the following documentation. MUIBuilder.library/MB_Open NAME MB_Open SYNOPSIS bool = MB_Open(); BOOL MB_Open( void ); FUNCTION Opens the MUIBuilder temporary files, and initializes global variables. RESULT bool : a boolean : the function returns TRUE ( 1 ) if all file openings and memory allocations have succeeded WARNING none of the other functions will work if this one is not successful SEE ALSO MB_Close() MUIBuilder.library/MB_Close NAME MB_Close SYNOPSIS MB_Close(); void MB_Close( void ); FUNCTION Closes the temporary files and deallocates memory WARNING don't forget to call this function before exiting your generator, even if MB_Open() call failed. SEE ALSO MB_Open() MUIBuilder.library/MB_GetA NAME MB_GetA MB_Get SYNOPSYS MB_GetA( Tags ); A1 MB_GetA( struct TagItem * ); MB_Get ( Tag Tag1, ... ); FUNCTION This function enables you to get the initialization values for the generator ( such as the file name of the file you have to create ... ) These values are here to give you some informations, such as the name of the file to generate, the name of the catalog file, the number of variables needed in the program the generator must create ... and so on ... INPUTS tags - pointer to a tag list TAGS tags for use with this function: MUIB_FileName ( STRPTR* ) - returns the name of the file to generate. MUIB_CatalogName( STRPTR* ) - same as above for MUIB_FileName returns the name of the .cd file. MUIB_GetStringName( STRPTR* ) - same as above for MUIB_FileName returns the name of the GetString function. MUIB_Code( BOOL* ) - return in the variable if the user wants the code to be generated. MUIB_Environment ( BOOL* ) - will return TRUE in the variable if the user wants an environment You must interpret this value in the generator. (please try GenCodeC to see the consequence) MUIB_Locale ( BOOL* ) - will return TRUE if the user wants a localised code MUIB_Declarations ( BOOL* ) - will return TRUE if the user wants the declarations MUIB_VarNumber ( ULONG* ) - will return in the variable the number of variables declared in the generated code MUIB_Application ( BOOL* ) - will return TRUE in the given variable if the user generates the whole application EXAMPLE ULONG varnb; BOOL Code, Env, Locale, Declarations; char *FileName, *CatalogName, *GetString; MB_Get ( MUIB_VarNumber , &varnb, MUIB_Code , &Code, MUIB_Environment , &Env, MUIB_Locale , &Locale, MUIB_Declarations , &Declarations, MUIB_FileName , &FileName, MUIB_CatalogName , &CatalogName, MUIB_GetStringName , &GetString, TAG_END ); After this call : - varnb contains the number of variables to be generated - Code contains TRUE or FALSE (depending on the user choice) - Env contains TRUE or FALSE - Declarations contains TRUE or FALSE - FileName is a pointer on the File name - CatalogName is a pointer on the Catalog name - GetString is a pointer on the GetString function name WARNING this function will do NOTHING if MB_Open() was not successful, or was not called. SEE ALSO MB_GetVarInfoA, MB_GetNextCode, MB_GetNextNotify. MUIBuilder.library/MB_GetVarInfoA NAME MB_GetVarInfoA MB_GetVarInfo SYNOPSYS MB_GetVarInfoA( variable_number, Tags ); D0 A1 MB_GetVarInfoA( ULONG, struct TagItem * ); MB_GetVarInfo ( ULONG, Tag Tag1, ... ); FUNCTION get infos on the variable number 'variable_number'. This info can be its name, its size, its type or how you have to initialise the variable. INPUTS variable_number - number of the variable for which you want to get info Tags - pointer to a list of tags giving the information you want to get TAGS MUIB_VarSize ( ULONG* ) - get the size of the variable this size is : - for a string array : its size - for a string : its length - for all other types : 0 MUIB_VarName ( STRPTR* ) - get the name of the variable MUIB_VarType ( ULONG* ) - get the type of the variable this type could be : - TYPEVAR_BOOL (1) Boolean - TYPEVAR_INT (2) Integer ( 4 bytes long ) - TYPEVAR_STRING (3) String Pointer - TYPEVAR_TABSTRING (4) Strings Array - TYPEVAR_PTR (5) Pointer - TYPEVAR_HOOK (6) Function Hook - TYPEVAR_IDENT (7) A constant identifier (i.e. ID_ReturnValue) - TYPEVAR_EXTERNAL (8) External variable - TYPEVAR_LOCAL_PTR (9) A pointer local to the Create procedure /* NEW TO VERSION 2.2 */ - TYPEVAR_EXTERNAL_PTR (10) A pointer to an object not defined in the code the user wants to generate. This pointer should appear as a parameter of the creation procedure. MUIB_VarInitPtr ( ULONG* ) - get the pointer to the init zone of the specified variable This 'init zone' could be : - a string ending with '\0' ( for a string ) - the list of the strings ( for a strings array ) - just a '\0' for all other types EXAMPLE ULONG i, type, size; char *name, *inits; MB_GetVarInfo( i, MUIB_VarType , &type, MUIB_VarName , &name, MUIB_VarSize , &size, MUIB_VarInitPtr , &inits, TAG_END ); WARNING this function will do NOTHING if MB_Open() was not successful, or was not called. SEE ALSO MB_GetA(), MB_GetNextCode(), MB_GetNextNotify() MUIBuilder.library/MB_GetNextCode NAME MB_GetNextCode SYNOPSIS MB_GetNextCode( type, code ); A0 A1 void MB_GetNextCode( ULONG*, char** ); FUNCTION get the next code element. You just have to read every code element. Then you react depending on the code element type you receive. RESULT type - will contain the type of the code element to write this type could be : TC_CREATEOBJ : creation of a MUI object TC_ATTRIBUT : name of an object attribute TC_END : end of an object creation TC_FUNCTION : opening of a function TC_STRING : a string TC_INTEGER : an integer TC_CHAR : a character TC_VAR_AFFECT : affectation of a variable TC_VAR_ARG : variable as argument TC_END_FUNCTION : end of a function call TC_BOOL : boolean TC_MUIARG : a mui argument TC_OBJFUNCTION : function creating an object TC_LOCALESTRING : a locale string reference TC_EXTERNAL_CONSTANT : reference to an external constant (i.e. not created by MUIBuilder) TC_EXTERNAL_FUNCTION : reference to an external function (i.e. not created by MUIBuilder) TC_MUIARG_ATTRIBUT : a MUI attribute as argument TC_MUIARG_FUNCTION : a function as argument TC_MUIARG_OBJ : an object as argument of a MUI attribute TC_BEGIN_NOTIFICATION : the beginning of a notification TC_END_NOTIFICATION : the end of a notification TC_EXTERNAL_VARIABLE : reference to an external variable (ie not generated by MUIBuilder) TC_MUIARG_OBJFUNCTION : an object function as argument TC_OBJ_ARG : an object take as argument TC_LOCALECHAR : a locale char code - is a pointer, and will contain the pointer to the code you have to write. THIS CODE IS ALWAYS A STRING. to obtain a number or a boolean, you have to convert this string ! type / code obtained TC_CREATEOBJ : the number of the object TC_ATTRIBUT : the number of the attribute TC_END : the number of 'End' TC_FUNCTION : the number of the function TC_STRING : the string ( ending with '\0' ) TC_INTEGER : the value of the integer TC_CHAR : the character TC_VAR_AFFECT : the number of the variable ( you can get infos with MB_GetVarInfo ) TC_VAR_ARG : the number of the variable TC_END_FUNCTION : the number of 'End' TC_BOOL : '0' [ FALSE ] or '1' [ TRUE ] TC_MUIARG : the number of the MUI string TC_OBJFUNCTION : the number of the MUI function TC_LOCALESTRING : the string MSG_xxxxx ( ending with '\0' ) TC_LOCALECHAR : the string MSG_xxxxx ( ending with '\0' ) TC_EXTERNAL_CONSTANT : name of the constant TC_EXTERNAL_FUNCTION : name of the function TC_MUIARG_ATTRIBUT : number of the attribute TC_MUIARG_FUNCTION : Number of the function TC_MUIARG_OBJ : Number of the object TC_BEGIN_NOTIFICATION : Number of the variable taken as argument of the notification TC_END_NOTIFICATION : end of the notification (no special return) TC_EXTERNAL_VARIABLE : name of the variable TC_MUIARG_OBJFUNCTION : number of the object TC_OBJ_ARG : number of the object taken as argument When you read a TC_LOCALE_STRING, you will generate a call to a GetMBString function. There is then two case depending on the string in the catalog file : 1. A\00A try : In this case your function must return "A Try" 2. A Try : In this case your function must return "A Try" This function MUST use the user-defined GetString function. When you read TC_LOCALE_CHAR, you must return the first char of the String you get after the call to the user-defined GetString Function. EXAMPLE ULONG type; char *code; MB_GetNextCode( &type, &code ); switch ( type ) { . . . case TC_FUNCTION: ... break; . . case TC_VAR_ARG: ... break; . . . default: /* Do NOTHING to ensure compatibility with the next versions */ break; } WARNING this function will do NOTHING if MB_Open() was not successful, or was not called. SEE ALSO MB_GetA(), MB_GetVarInfoA(), MB_GetNextNotify(). MUIBuilder.library/MB_GetNextNotify NAME MB_GetNextNotify SYNOPSIS MB_GetNextNotify( type, code ); A0 A1 void MB_GetNextNotify( ULONG*, char** ); FUNCTION get the next notify element. ALL specifications are exactly the same as GetNextCode. The only difference is that this function gets the notify elements. WARNING this function will do NOTHING if MB_Open() was not successful, or was not called. SEE ALSO MB_GetA(), MB_GetVarInfoA(), MB_GetNextCode().
