Since we're on the topic how about another one-liner for reading all the files
in directory into a dynamic array? This has the added benefit of getting
enumeration for free. This is standard stuff for working with files in
scripting languages so I think the FPC RTL should include something like this
also.
================================
type
TStringArray = array of string;
function FindAllFiles(path: string): TStringArray;
var
info: TSearchRec;
begin
if not DirectoryExists(path) then
raise Exception.Create('Directory "'+path+'"" doesn''t exist');
path := path+DirectorySeparator+'*';
result := [];
if FindFirst(path, faAnyFile, info) = 0 then
begin
repeat
result += [info.name];
until FindNext(info) <> 0;
FindClose(info);
end;
end;
begin
// fastest way to read all text files in a directory.
// only 2 lines doesn't leak memory
for name in FindAllFiles('/usr/local/lib/fpc') do
writeln(GetFileAsString('/usr/local/lib/fpc/'+name));
end.
