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. -## Next +## 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`. + 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` where `E` is a generic that + can be constructed `From`. + + This all was triggered by the fact that `Store::entries()` did a + `.collect::>()` 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): + + Before, Debug build: + + 0,075;0,052;0,023 + 0,077;0,051;0,026 + 0,083;0,063;0,020 + 0,079;0,054;0,025 + 0,076;0,057;0,019 + 0,077;0,059;0,017 + 0,074;0,052;0,022 + 0,077;0,045;0,032 + 0,080;0,060;0,020 + 0,080;0,058;0,022 + + After, Debug build: + + 0,071;0,050;0,021 + 0,073;0,053;0,021 + 0,075;0,060;0,015 + 0,076;0,047;0,029 + 0,072;0,055;0,018 + 0,077;0,061;0,016 + 0,071;0,053;0,019 + 0,070;0,053;0,016 + 0,074;0,050;0,025 + 0,076;0,052;0,024 + + Before, Release build: + + 0,034;0,015;0,019 + 0,034;0,017;0,017 + 0,034;0,019;0,015 + 0,033;0,012;0,022 + 0,034;0,011;0,023 + 0,034;0,015;0,019 + 0,034;0,010;0,024 + 0,033;0,015;0,018 + 0,037;0,017;0,020 + 0,033;0,013;0,021 + + After, Release build: + + 0,037;0,015;0,022 + 0,036;0,016;0,020 + 0,036;0,018;0,018 + 0,036;0,014;0,022 + 0,036;0,015;0,021 + 0,036;0,018;0,018 + 0,037;0,016;0,020 + 0,036;0,018;0,018 + 0,039;0,015;0,023 + 0,037;0,016;0,021 + +* The `Store::walk()` function was removed. + +* `imag-ids` got the ability to filter by header + + The language introduced here is subject to change, but a good first step into + the direction of a generic filter language. + + Language documentation was added as well and is printed with `imag ids --help`. + +* `imag-category` was added + +* The standard CLI interface in `libimagrt` was updated and validations were + added -* Major changes -* Minor changes -* Bugfixes ## 0.7.1
