Why are my visible line ending different?

[Andrew Truckle]

I understand that there are three flavours of line endings:

1. LF
2. CR
3. CRLF

When I open my file with NotePad++ the line endings are CRLF:

But, when using the Scintilla control they are CR:

This is my code for reading the file:

void CScintillaHelper::ReadFile(const CString& filePath)
{
std::ifstream file(filePath);
if (file.is_open())
{
m_edit.ClearAll();
std::string line;
while (std::getline(file, line))
{
m_edit.AppendText(line.size(), line.c_str());
m_edit.AppendText(1, L"\r\n");
}
file.close();
m_edit.SetSavePoint();
}
}

Why is this? Not a big issue.

Andrew Truckle:

> m_edit.AppendText(1, L"\r\n");

"\r\n" contains 2 characters, not 1.

Hi Neil

Thanks for your response. But, I specifically used \r\n in my code (CR LF).. Notepad++ correctly show these line endings as CRLF. My question is about why my attempt at displaying the same file in Scintilla is only showing CR for the same file?

Another resolved issue. Changing the way I read the file corrected the line ending matter:

void CScintillaHelper::ReadFile(const CString& filePath)
{

ifstream ifs(filePath, ios::in | ios::binary | ios::ate);

const ifstream::pos_type fileSize = ifs.tellg();
ifs.seekg(0, ios::beg);

vector<char> bytes(fileSize);
ifs.read(bytes.data(), fileSize);

m_edit.AppendText(fileSize, std::string(bytes.data(), fileSize).c_str());
m_edit.SetSavePoint();
}
