| Module | Snarl::SnarlAPI |
| In: |
lib/snarl.rb
|
This is the lowlevel API implemenation using DL and a few handy constants from the snarl api and the Win32 API Note that I have jump through some hoops to get the array of characters to work corretly — if you know a better way please send me (phurley@gmail.com) a note.
| SNARL_SHOW | = | 1 |
| SNARL_HIDE | = | 2 |
| SNARL_UPDATE | = | 3 |
| SNARL_IS_VISIBLE | = | 4 |
| SNARL_GET_VERSION | = | 5 |
| SNARL_REGISTER_CONFIG_WINDOW | = | 6 |
| SNARL_REVOKE_CONFIG_WINDOW | = | 7 |
| SNARL_TEXT_LENGTH | = | 1024 |
| WM_COPYDATA | = | 0x4a |
| SnarlStruct | = | struct [ "int cmd", "long id", "long timeout", "long data2", "char title[#{SNARL_TEXT_LENGTH}]", "char text[#{SNARL_TEXT_LENGTH}]", "char icon[#{SNARL_TEXT_LENGTH}]", ] |
| CopyDataStruct | = | struct [ "long dwData", "long cbData", "void* lpData", ] |
Send the structure off to snarl, the routine will return (if everything goes well) the result of SendMessage which has an overloaded meaning based upon the cmd being sent

60: def self.send(ss)
61: if isWindow(hwnd = findWindow(nil, 'Snarl'))
62: cd = CopyDataStruct.malloc
63: cd.dwData = 2
64: cd.cbData = ss.size
65: cd.lpData = ss.to_ptr
66: sendMessage(hwnd, WM_COPYDATA, 0, cd.to_ptr)
67: end
68: end
character array hoop jumping, we take the passed string and convert it into an array of integers, padded out to the correct length to_cha —> to character array I do this as it seems necessary to fit the DL API, if there is a better way please let me know
# File lib/snarl.rb, line 52
52: def self.to_cha(str)
53: result = str.split(/(.)/).map { |ch| ch[0] }.compact
54: result + Array.new(SNARL_TEXT_LENGTH - result.size, 0)
