Notes

The unit Strwrap1 contains many useful string, file, and functions that can be used in web programs. It is a very compact and lean unit since it does not rely on sysutils or classes.

At current time of writing you can download the latest version of strwrap1 here:

• strwrap1.pas
• Old server: /extras/strwrap1/strwrap1.pas

Some of the most notable functions in the unit are StrSaveFile and StrLoadFile. These functions act as stringtofile and filetostring functions (strtofile, string2file, file2string, filetostr).

Other notable functions are:

• OpenFileRead (alternative than using assign/reset .. does it in one shot))

• OpenFileReWrite (alternative to using assign/rewrite .. does it in one shot))

• OpenFile (alternative to using assign/rewrite/reset .. does it in one shot)

• MakeDir (make directory in one shot, hiding IORESULT code bloat)

• ReadChunk

• SaveChunk

• GetLineCount (quick easy way to find out amount of lines in a file)

• FindLine

• GetFileSize (quick easy way to determine file size)

• StrLoadFile

• StrSaveFile

• StrLoadLns (load specific lines of a file into string)

• StrLoadRng

• GetLn1 (get line one from a file into a string)

• GetLn2

• GetLnN (get specfic line number from a file into a string)

• ArrayLoadFile (load file into an array of strings)
