In SVN you can set eol-style to native, and it converts line endings when the

Standardize on \n
Here's a simple program to do it (tolf.d):
/* Replace line endings with LF
*/
import std.file;
import std.path;
int main(string[] args)
{
foreach (f; args[1 .. $])
{
auto input = cast(char[]) std.file.read(f);
auto output = filter(input);
if (output != input)
std.file.write(f, output);
}
return 0;
}
char[] filter(char[] input)
{
char[] output;
size_t j;
for (size_t i = 0; i < input.length; i++)
{
auto c = input[i];
switch (c)
{
case '\r':
c = '\n';
break;
case '\n':
if (i && input[i - 1] == '\r')
continue;
break;
case 0:
continue;
default:
break;
}
output ~= c;
j++;
}
return output[0 .. j];
}
Yes, I'm sure it can be done in linux with a 1 line script, but my
linux-fu is weak :-(
Here's it's companion program detab.d that I use before checkins:
/* Replace tabs with spaces, and remove trailing whitespace from lines.
*/
import std.file;
import std.path;
int main(string[] args)
{
foreach (f; args[1 .. $])
{
auto input = cast(char[]) std.file.read(f);
auto output = filter(input);
if (output != input)
std.file.write(f, output);
}
return 0;
}
char[] filter(char[] input)
{
char[] output;
size_t j;
int column;
for (size_t i = 0; i < input.length; i++)
{
auto c = input[i];
switch (c)
{
case '\t':
while ((column & 7) != 7)
{ output ~= ' ';
j++;
column++;
}
c = ' ';
column++;
break;
case '\r':
case '\n':
while (j && output[j - 1] == ' ')
j--;
output = output[0 .. j];
column = 0;
break;
default:
column++;
break;
}
output ~= c;
j++;
}
while (j && output[j - 1] == ' ')
j--;
return output[0 .. j];
}
