Hi,

I want to read two fields from STDIN

Well it's so different from C. I would use this:

---
auto t = line_st.split.join (' ');
t.formattedRead!"%s %f"(key, value);

Yes it's possible.

It's a little weird and it seems the "feature" (or bug) is not 
documented on https://dlang.org/phobos/std_format.html. Why a tab 
(`\t`) isn't considered as a space?

formattedRead can't work with tab delimiter input

Hi,

I want to read two fields from STDIN

string key;
double value;
line_st.formattedRead!"%s %f"(key, value);

However, if the input line contains \t and it doesn't contain any 
space, the code doesn't work as expected. If there is a space, it 
works well


   a[space]1 # work, key => a, value => 1
   b[space][tab]2# work, key => b, value => 2
   c[tab]3   # not work, key => c[tab]3, value => nan

Can you please help? Thanks a lot.
