The _EMBEDDED$ function is used to recall the data of a file which was earlier embedded into the EXE file using the $EMBED metacommand. You can roughly compare this to a RESTORE to any DATA block and then using READ to retrieve the data.
Syntax
- filedata$ = _EMBEDDED$("handle")
Parameters
- IMPORTANT
-
- The parameter handle must be given as a literal string enclosed in quotes, variables cannot be used here.
- The parameter will be checked while typing to ensure its validity, warnings (if any) will be displayed immediately in the IDE status area.
- The filedata$ will receive the embedded file data as a single contiguous string, just as you would regularly OPEN the file and read its entire contents into that string.
- The handle is a unique case sensitive identifier beginning with a letter and only containing lower/upper case letters and/or numbers. It must exactly match the handle value used to $EMBED the respective file.
Description
- Embedding files can be useful to deliver a program inclusive all required assets in just one EXE file.
- No more worries whether a user installs your program correctly and retains the required folder structure.
- If required, you can write the files back to disk, i.e. it could serve as an simple installer or package manager.
- Embedded images, sounds or fonts can be passed directly to _LOADIMAGE, _SNDOPEN or _LOADFONT respectively when using the memory load capabilities of these functions.
- To easily embed a file into your compiled EXE file, use the $EMBED metacommand.
