More path manipulation commands

[tinman]

Hi,

In addition to GetExtensionPart(), GetFilePart() and GetPathPart() I'd like to see more commands for manipulating paths in an OS independant way.

AppendPath() - append one path onto another (making sure there are not two drives in the resulting path, taking care of directory separators etc).

RemovePart() - removes the last element from a path (either a directory or filename). Useful for navigating/finding to parent directories.

RemoveExtension() - remove the extension and the separator.

Apologies if this has already been requested, I searched but didn't find anything.

+1, and don't forget GetDrivePart() that I requested here:

+1

And it's not enough:
GetFilePartWithoutExtension() - returns the filename without extension

Code: Select all

Procedure.s GetFilePartWithoutExtension(File.s)
  Protected *c.Character = @File, tmp.s = "", Result.s
  
  While *c\c
    If *c\c = '\'
      tmp = ""
      Result = ""
    ElseIf *c\c = '.'
      Result = tmp
      tmp + Chr(*c\c)
    Else
      tmp + Chr(*c\c)
    EndIf
    *c + SizeOf(Character)
  Wend
  
  If Result
    ProcedureReturn Result
  Else
    ProcedureReturn tmp
  EndIf
EndProcedure

Debug GetFilePartWithoutExtension("C:\path\hi.hello.txt") ;"hi.hello"
Debug GetFilePartWithoutExtension("C:\path\hi.hello")     ;"hi"
Debug GetFilePartWithoutExtension("C:\path\hi.hello\")    ;""

> GetFilePartWithoutExtension() - returns the filename without extension

Isn't that the same as the RemoveExtension() request?

[NicTheQuick]

I think RemoveExtension() returns the whole path + filename without
extension, isn't it?

So, without getting into command name details, and so we understand what we want (thus far) is this it?


* Append one path onto another.
Perhaps expand on this. Are we saying "C:\path\subpath\A\" 'appended with' "C:\path\subpath\B\" equals "C:\path\subpath\A\B\" or a straight drive-less concatenation "C:\path\subpath\A\path\subpath\B\")? Or something else?

* Remove the last logical element from a path, step by step would reduce it to just the drive.
-> "C:\path\subpath\A\myFile.exe"
-> "C:\path\subpath\A\"
-> "C:\path\subpath\"
-> "C:\path\subpath\"
-> "C:\path\"
-> "C:\"
With the file and extension being a logical element.

* Remove the extension and the separator from the path. (Leaving the path and the file)
-> "C:\path\subpath\A\myFile.exe"
-> "C:\path\subpath\A\myFile"


* Get the drive from a path.
-> "C:\path\subpath\A\myFile.exe"
-> "C:\"

* Get the file less extension.
-> "C:\path\subpath\A\myFile.exe"
-> "myFile"


Is this correct?



(Most of which we can do with stringfield or similar coding but dedicated commands would be quicker and easier to understand and "in context" - and in my case, less subject to error!)
