# RecFind.nsh - Recursive FindFirst, FindNext, FindClose.
#  by Afrow UK
#
# Last modified 5th July 2005

; Usage:
; ------------------------------------------------------------
; ${RecFindOpen} "Dir\Path" $CurrentDirVar $CurrentFileVar
;  ... Do stuff with $CurrentDirVar ...
; ${RecFindFirst}
;  ... Do stuff with $CurrentFileVar ...
; ${RecFindNext}
; ${RecFindClose}

; Notes:
; ------------------------------------------------------------

; Looping is handled by the macro's internally.

; ${RecFindOpen} opens a search in a new directory in the tree.
;  The macro's will loop back to this instruction when a new
;  directory is opened for searching.

; ${RecFindFirst} gets file names out of the current directory.
;  The macro's will loop back to this instruction when a new file
;  is found.

; ${RecFindNext} gets the next file in the current directory, and loops to
;  ${RecFindFirst} again.

; ${RecFindClose} closes the search and clears the stack.

; Example 1:
; ------------------------------------------------------------
; ${RecFindOpen} "C:\Dir" $R0 $R1
;  DetailPrint "Dir: C:\Dir$R0"
; ${RecFindFirst}
;  DetailPrint "File: C:\Dir$R0\$R1"
; ${RecFindNext}
; ${RecFindClose}

; Example 2:
; ------------------------------------------------------------
; ${RecFindOpen} "C:\Dir" $R0 $R1
;  DetailPrint "Dir: C:\Dir$R0"
; ${RecFindFirst}
;  DetailPrint "File: C:\Dir$R0\$R1"
;  StrCmp $R1 "a_file.txt" Found
; ${RecFindNext}
;  Found:
; ${RecFindClose}
