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.
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.
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.
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 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.
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 test is not applicable anymore because it tests (and tested) the
wrong thing.
It was to check whether the function failed because the "imag" key
contained the wrong type, but this is not tested by that function. The
function only checks whether the "imag" key is present.
Before we extracted the store configuration from the configuration
toml::Value object and passed it to the store.
This is unecessary overhead.
Now we pass the whole configuration object and let the store extract the
required values.
Before the configuration object (the raw TOML object) was provided via a
wrapper object `Configuration`. This was ugly and not very nice to use.
Now, we only have the `toml::Value` object we lend out from
`Runtime::config()`.
The changes included libimagrt internal rewrites, which are not visible
to the user. Anyways, this change changes the API for config-fetching
from the runtime, so fixes for all other crates may follow.
The changes also removed the support for reading the "editor" setting
from the configuration file, which was not used anyways (in the example
imagrc.toml file).
The CLI-reading and ENV-reading are still supported, though.
Formerly, the --debug flag was ignores. This change overrides the
logging with the CLI specified logging if it was provided.
If --debug was provided, the logging is set to debugging, if --verbose
was provided info logging is used.
Before the iterator did also yield storeids for directories, which was a
bug.
This change introduces a new if_file() function in the store-internal
backend, which is needed to check whether a path actually points to a
File, be it inmemory or on the real filesystem.
That's because tests might fail if they check via PathBuf::is_file() as
in tests, the entries only exist inmemory.
