[Gambas-user] Counting characters

[Fabien Bodard]

maybe with gb.pcre : regexp

or
Public Function CountChar(sValue as string, sChar as string) as integer
dim i, iRet as integer

for i =1 to len (sValue)+1
  if mid(sValue,i,1)=sChar then inc iRet
next

return iRet
end


print CountChar("coucou ça va ?", "a")

$ 2

Or a super version thet remember a position:

Public Function GetCharPos(sValue as string, sChar as string) as integer[]
dim i as integer
dim  aRet as new integer[]

for i =1 to len (sValue)+1
  if mid(sValue,i,1)=sChar then aRet.add(i)
next

return aRet
end


print GetCharPos("Hello how are you", "e").Count
