Merge pull request #1330 from matthiasbeyer/libimagrt/pipe-magic
Implement pipe magic in libimagrt
2018-03-10 16:20:36 +01:00
ce0bd9298a Implement pipe magic in libimagrt
When we merged the changes in libimagrt so that it automatically detects
whether stdin/stdout is a TTY and provides the user with stderr in case
stdout is not a TTY, we forgot that things like

    imag foo | grep bar

becomes impossible with that, because imag detects that stdout is not a
tty and automatically uses stderr for output.

But in this case, we don't want that. The output has to be stdout in
this case.

With this change, we have a flag in the runtime ("--pipe-magic" or "-P",
globally available) which turns on "pipe magic".

The expected behaviour is the following, if "-P" is passed:

* If stdout is a TTY, we print to stdout
* If stdout is not a TTY, we print to stderr
* If stdin is not a TTY, we do not provide it

If "-P" is not passed, we allow the user of libimagrt to use stdin for
interactive stuff (the interactive stuff is not yet implemented).

da408b9e67 This fixes the file parsing (again)
Unfortunately, our latest fix to file parsing did not solve all issues.
So we have to fix it _again_.

The problem was the `std::str::Lines` iterator, which apparently fails
this:

    assert_eq!(1, "".lines().count());

as an empty line seems not to be a line.

Because of that, when reading a file with an empty line at its bottom
got stripped off that line.

This patch removes the use of the `lines()` iterator and uses
`split("\n")` instead. This only works on Unix operating systems, but as
we only target unix operating systems with imag, this is not considered
an issue right now.

This patch also adds extensive tests on multiple levels in the
`libimagstore` implementation:

* On the parsing level, for the function which implements the parsing
* On the filesystem abstraction levels
* On the `Store` levels

to make sure that everything is parsed correctly.

19e9dfe33c Implement proxy object where runtime configures output
This is another approach for providing access to stdin/out/err via
libimagrt::runtime::Runtime.

The Runtime object does configure which output gets returned (stdout if
stdout is a tty, else stderr).

With this we can change libimagrt to read/write the store from/to
stdin/stdout without the user noticing that she does not write to stdout
but stderr.
Reading from stdin is not possible then, though.

c18c0bbbe4 Provide stdin/out/err resources via Runtime object
This way we can control whether "out" output goes to stdout or stderr
without the user of the functionality knowing.

This is useful for later when we use libimagrt to automatically
read and write the store from and to stdout/in depending on whether we
are talking to a TTY or a pipe.

78fe9b8cc5 Change "imag" impl to not instantiate Runtime object
Adapt libimagrt interface to export the functions we need to do this.
This is not that nice, but the best approach without rewriting large
parts of libimagrt.

Rewrite entry parsing algorithm
2018-02-20 22:03:00 +01:00
9fb5f453fe Rewrite entry parsing algorithm
Rewrite without regex crate.

The regex approach was broken. If the following _content_ was provided
in the entry:

    foo

    ---

    bar

The regex approach parsed the header until the "---" in the content.
This is, of course, not the way to do that.

Now, the parsing is implemented by hand. Should be faster as well,
though I don't care about this.

This fixes a severe bug.

3b01a9eb2f Add API in StoreIdIteratorWithStore to get acting iterators
This patch adds API functions in the StoreIdIteratorWithStore iterator
type to transform it into a iterator which _does_ something (as in the
`libimagstore::iter` API).

It mimics the API which is offered by `libimagstore::iter`.

This change is needed so we can refactor the "get" iterator to not take
an argument (the store) later, which improves the API.
