Please note that we do not have a "Breaking changes" section as we are in
|
||||
Version 0.y.z and thus we can break the API like we want and need to.

## 0.8.0
|
||||
|
||||
This section contains the changelog from the last release to the next release.
|
||||
After the last release (0.7.0), we changed how we keep our changelog from manual
|
||||
adding things to the list, to using `git-notes`. Hence, there's no
|
||||
categorization anymore.
|
||||
|
||||
* Add imag-diary functionality to list existing diaries
|
||||
|
||||
* `libimagentryview`s `StdoutViewer` is now able to wrap lines
|
||||
|
||||
* `imag-view` can wrap output now
|
||||
|
||||
* `imag tag` is now able to read store ids from stdin
|
||||
|
||||
* `libimagrt` automatically suggests "imag init" if config is not found
|
||||
|
||||
* A changelog-generation script was added to the scripts/ directory
|
||||
|
||||
* Fix: `libimagdiary` did not return the youngest, but the oldest entry id on
|
||||
`::get_youngest_entry_id()`.
|
||||
|
||||
* Fix: imag-view should not always wrap the text, only if -w is passed
|
||||
|
||||
* Fix: `imag-log show` should order by date
|
||||
|
||||
* `imag` does not inherit stdout if detecting imag command versions.
|
||||
|
||||
* The `Store::retrieve_for_module()` function was removed.
|
||||
|
||||
* `imag-git` was added, a convenient way to call `git` in the imag RTP.
|
||||
|
||||
* `libimagentryview` was refactored.
|
||||
The crate was refactored so that the "sink" - the thing the view should be
|
||||
written to - can be passed.
|
||||
|
||||
* A `imag-view` feature was added where markdown output can be formatted nicely
|
||||
for the terminal
|
||||
|
||||
* The libimagstore lib got its stdio backend removed.
|
||||
|
||||
First, `imag store dump` was removed as it was based on this feature.
|
||||
Then, `libimagrt` got the ability removed to change the store backend to stdio.
|
||||
After that, we were able to remove the stdio backend and the JSON mapper
|
||||
functionality that came with it.
|
||||
|
||||
This shrinked the codebase about 1kloc.
|
||||
|
||||
The `imag store dump` feature can be reimplemented rather simply, if desired.
|
||||
|
||||
* `imag-view` is now able to seperate printed entries with a user-defined
|
||||
character (default: "-")
|
||||
|
||||
* Fix: Deny non-absolute import pathes in imag-contact
|
||||
|
||||
* libimagcontact is not based on libimagentryref anymore
|
||||
|
||||
This is because we encountered a serious problem: When syncing contacts with an
|
||||
external tool (for example `vdirsyncer`), the files are renamed on the other
|
||||
host. Syncing the imag store to the other device now creates dead links, as the
|
||||
`path` stored by the ref is not valid anymore.
|
||||
|
||||
Now that libimagcontact is not based on libimagentryref anymore, this issue does
|
||||
not exist anymore. libimagcontact stores all contact information inside the
|
||||
store now.
|
||||
|
||||
imag-contact was rewritten for that change.
|
||||
|
||||
* Fix: imag-contact does only require the name field, all others are optional
|
||||
now
|
||||
|
||||
* Fix: imag-contact automatically creates a UID now
|
||||
|
||||
* `libimagcategory` was rewritten
|
||||
|
||||
It creates entries for categories now and automatically links categorized
|
||||
entries to the "category" entries.
|
||||
|
||||
Its codebase got a bit simpler with these changes, despite the increase of
|
||||
functionality.
|
||||
|
||||
* `imag-contact` automatically generates/warns about missing file extension
|
||||
|
||||
* `libimagcontact` does export email properties now.
|
||||
|
||||
`imag-contact` reads email properties and can output them in its JSON output.
|
||||
This is helpful for passing email adresses to external tools like mutt.
|
||||
|
||||
* `libimagentrygps` and `imag-gps` work with 64 bit signed values now
|
||||
|
||||
Both the library and the command use i64 (64 bit signed) for GPS value fragments
|
||||
now.
|
||||
|
||||
Also: The `imag-gps` tool does not require a "second" value fragment now, it
|
||||
defaults to 0 (zero) if not present.
|
||||
|
||||
* The `filters` dependency was updated to 0.3
|
||||
|
||||
* `libimagentryfilter` filters headers not with a failable filter.
|
||||
|
||||
* `imag-diary` has no longer an `edit` command. `imag-edit` shall be used
|
||||
instead.
|
||||
|
||||
* `libimagtodo` got a error handling refactoring, so that more chaining happens.
|
||||
|
||||
* Errors in `libimagstore` contain more details in the error message about what
|
||||
StoreId caused the error
|
||||
Unused errors were removed.
|
||||
|
||||
* The Store API got functions to get data about the internal cache and flush it
|
||||
|
||||
* imag-diagnostics flushes the cache each 100 entries processed
|
||||
|
||||
* The iterator interface of libimagstore was refactored
|
||||
|
||||
Originally, the iterator interface of libimagstore did not return errors which
|
||||
could happen during the construction of a `StoreId` object.
|
||||
This was refactored, effectively changing the `StoreIdIterator` type to not
|
||||
iterate over `StoreId` anymore, but over `Result<StoreId, StoreError>`.
|
||||
That cause a lot of changes in the overall iterator interface. All iterator
|
||||
extensions (like `.into_get_iter()` for example) had to be rewritten to be
|
||||
applicable on iterators over `Result<StoreId, E>` where `E` is a generic that
|
||||
can be constructed `From<StoreError>`.
|
||||
|
||||
This all was triggered by the fact that `Store::entries()` did a
|
||||
`.collect::<Vec<_>>()` call, which is time consuming.
|
||||
Consider a tool which calls `Store::entries()` and then only use the first 10
|
||||
entries returned (for some user-facing output for example). This would
|
||||
effectively cause the complexe store to be accessed (on the filesystem level),
|
||||
which could be thousands of entries. All relevant pathes would have been written
|
||||
to memory and then be filtered for the first 10.
|
||||
Not very optimized.
|
||||
|
||||
After this was done, the store interface changed. This caused a lot of changes
|
||||
in almost all crates.
|
||||
|
||||
Internally, in the store, the `FileAbstraction` object is not passed around in a
|
||||
`Box` anymore, but in an `Arc`, as a intermediate (store-private) iterator type
|
||||
needs to access the backend for file-system level checks.
|
||||
This is not user-facing.
|
||||
|
||||
In the process, the `Store::reset_backend()` interface was removed (as this is
|
||||
no longer supported and should've been removed already). Rewriting it just for
|
||||
the sake of this patch and then removing it would've been to difficult and time-
|
||||
consuming, hence it was simply removed during that patchset.
|
||||
|
||||
The overall performance was somewhat improved by this patchset.
|
||||
A rather non-scientifically performed test shows increased performance in debug
|
||||
builds (but slowing down in release builds).
|
||||
|
||||
The test was done on master before the merge and after the merge, with a debug
|
||||
build and a release build. Each time, `imag-ids` was executed 10 times with its
|
||||
output piped to /dev/null. The local store used for this contained 5743 entries
|
||||
during the measurements and was not changed in between. `time` showed the
|
||||
following data (real, user, sys):

the direction of a generic filter language.
|
||||
|
||||
Language documentation was added as well and is printed with `imag ids --help`.
|

|

* `imag-category` was added
|
||||
|
