/*!
A library for iterating through the lines in a series of
files. Very similar to [the Python module of the same
name](http://docs.python.org/3.3/library/fileinput.html).
It allows the programmer to automatically take filenames from the
command line arguments (via `input` and `input_state`), as well as
specify them as a vector directly (`input_vec` and
`input_vec_state`). The files are opened as necessary, so any files
that can't be opened only cause an error when reached in the
iteration.
On the command line, `stdin` is represented by a filename of `-` (a
single hyphen) and in the functions that take a vector directly
(e.g. `input_vec`) it is represented by `None`. Note `stdin` is *not*
reset once it has been finished, so attempting to iterate on `[None,
None]` will only take input once unless `io::stdin().seek(0, SeekSet)`
is called between.
The `make_path_option_vec` function handles converting a list of file paths as
strings to the appropriate format, including the (optional) conversion
of `"-"` to `stdin`.
# Basic
In many cases, one can use the `input_*` functions without having
to handle any `FileInput` structs. E.g. a simple `cat` program
for input |line| {
io::println(line)
}
or a program that numbers lines after concatenating two files
for input_vec_state(make_path_option_vec([~"a.txt", ~"b.txt"])) |line, state| {
io::println(format!("{}: %s", state.line_num,
line));
}
The two `input_vec*` functions take a vec of file names (where empty
means read from `stdin`), the other two functions use the command line
arguments.
# Advanced
For more complicated uses (e.g. if one needs to pause iteration and
resume it later), a `FileInput` instance can be constructed via the
`from_vec`, `from_vec_raw` and `from_args` functions.
Once created, the `each_line` (from the `std::io::ReaderUtil` trait)
and `each_line_state` methods allow one to iterate on the lines; the
latter provides more information about the position within the
iteration to the caller.
It is possible (and safe) to skip lines and files using the
`read_line` and `next_file` methods. Also, `FileInput` implements
`std::io::Reader`, and the state will be updated correctly while
using any of those methods.
E.g. the following program reads until an empty line, pauses for user
input, skips the current file and then numbers the remaining lines
(where the numbers are from the start of each file, rather than the
total line count).
let input = FileInput::from_vec(pathify([~"a.txt", ~"b.txt", ~"c.txt"],
true));
for input.each_line |line| {
if line.is_empty() {
break
}
io::println(line);
}
io::println("Continue?");
if io::stdin().read_line() == ~"yes" {
input.next_file(); // skip!
for input.each_line_state |line, state| {
io::println(format!("{}: %s", state.line_num_file,
line))
}
}
