# imag - [imag-pim.org](http://imag-pim.org)
Imag is a CLI PIM suite you can
integrate in your tools of choice (Editor, MUA, RSS reader, etc etc).
`imag` is a commandline personal information management suite.
**This application is in early development. There are _some_ things that work,
but we do not consider anything stable or usable at this moment. Feel free to
play around anyways.**

## What is this / Goal and Functionality
We are looking work contributors!
Our (long-term) goal is to

available in the issue tracker you can start with and we are open to questions!
Feel free to open issues for asking questions, suggesting features or other
things!

## Goal
Our goal is to
> Create a fast, reliable, forwards/backwards compatible commandline personal
> Create a fast, reliable commandline personal
> information management suite which covers all aspects of personal information
> management, consists of reusable parts and integrates well with known
> commandline tools.
We try to accomplish these requirements:
We try to implement as many aspects of personal information management (PIM),
but re-use existing commandline tools.
We do this by tracking/referring to the data the tools create.
A user can now link pieces of data (from different tools), tag this data and
query/search this data using imag.
So `imag` is more like a data-mining helper than an actual PIM tool, but we
implement some of the PIM aspects directly in `imag`.
Parts of PIM (we call them "modules") that are already implemented and basically
working:
* "fast": We use the awesome, fast and safe programming language "Rust"
* "reliable": We try to test every aspect of our software. Our build process
ensures that the build breaks whenever a library interface changes and the
modules which use the library are not updated.
* "forwards/backwards compatible:" Our (plain text) on-disk data format and
storage library both ensure that incompatibilities are captured and resolved
([using](https://crates.io/crates/semver) [semver](https://semver.org))
* "commandline": We ensure that everything can be done by commandline calls, for
some modules there might be a curses-like UI, but there are no graphical
clients and there never will be any within this codebase. We use
[clap](https://crates.io/crates/clap) for commandline-interface building and
we try to keep the interface easy and consistent between modules.
* "personal": We store everything as plain text in a store inside the users
`$HOME` directory. There will be a version-control (most surely `git`) hook
integrated to sync between several machines. There are no multi-user features
included or planned at the time of writing.
* "information management": We want to give the user the possibility to put
every single information about their personal lives into the store and we try
hard to provide a sane interface to query and retrieve data from this
database.
* "covers all the aspects of personal information management": We want to
provide modules for:
* contact management
* calendar
* diary
* notes
* personal wiki
* news (rss)
* passwords
* images
* music
* movies
* personal project management
* podcast management
* ledger
* mail
* bibliography management
* ... and many, many more.
* "constists of reusable parts": Every functionality is implemented as library.
The binaries we ship are just commandline-interace-to-library-interface
translators
* "integrates well with known commandline tools": We do not re-invent the wheel.
**We do not implement "yet another password manager", but use
[the standard unix password manager](https://www.passwordstore.org/), do not
implement a news reader, but use [newsbeuter](http://www.newsbeuter.org/),
do not reimplement a mail reader, etc etc.**
We do not copy images, movies or other data to the store but "link" them into
the store, so you can use imag tools to query and access this data, but still
live with your beloved commandline apps. We do not want to duplicate work but
reuse as much as possible.
You don't like one of the applications we use (for example `pass` as password
manager)? Sure, feel free to submit patches so the user is able to switch the
used tool, as long as it doesn't break the workflow. We will happily merge
them!
* todo (via taskwarrior, we track the tasks one creates in taskwarrior)
* diary
* notes
* bookmarks
* counter (just an example, nothing that usable)
## Current state of development
Helper modules that come with `imag` but are not "PIM aspects":
**This application is in _really_ early development.**
We have implemented the very core of the system, though some more utility work
is to be done.
We have the store working, a hooks API and some default hooks are in
development.
Basic features like tagging and linking entries is possible as well as viewing
entries.
Some small things are implemented, like a note-taking module, a basic diary
module, a counter module and a bookmark module.
These modules contain basic features and are subject to change.
More modules are about to be implemented.
Though, the very core of the system is stable and nothing prevents _you_ from
contributing and implementing a module.
* linking entries
* viewing entries
* tagging entries
* creating misc entries
* creating entries that refer to files/directories
## Building/Running
Here goes how to try imag out.
Here goes how to try `imag` out.
`imag` is a _suite_ of tools and you can build them individually.
All subdirectories prefixed with "`libimag"` are libraries for the respective
binaries.
All subdirectories prefixed with `"imag-"` are binaries and compiling them will
give you a commandline application.
### Building
By now, there are several targets in the Makefile, fulfilling following roles:
* `all` Is the default and builds every crate in debug mode. This is the same as
traversing every directory yourself and calling `cargo build` in it.
To build a single crate, call `make <crate>`, for example
`make imag-store`
* `release`, as the name implies, builds every crate in release mode. Following
the example above, to build `imag-store` in release mode, call
`make imag-store-release`.
* `install` will install all binary crates to the default installation root (see
`man cargo-install`). To install a single module, run `make <module>-install`,
again, for example: `make imag-store-install`
* `all` is the default and builds every crate in debug mode.
To build a single module, call `make <module>`, for example `make imag-store`.
* `release`, as the name implies, builds every module in release mode.
E.G.: `make imag-store-release` to build "imag-store" in release mode.
* `install` will install all commandline modules to the default installation
root (see `man cargo-install`).
To install a single module, run `make <module>-install`,
E.G.: `make imag-store-install`
* `bin`/`lib` are separate targets for either building all binaries or
libraries.
* `lib-test` runs `cargo test` for all libraries. For testing a single library,
run `make test-libimagstore` for example.
* `clean` will run `cargo clean` in every crate. Again, for cleaning a single
crate, use `make imag-store-clean` for example.
* `lib-test` runs `cargo test` for all libraries.
For testing a single library, E.G.: `make test-libimagstore`.
* `clean` will run `cargo clean` in every crate.
For cleaning a single crate, use `make imag-store-clean` for example.
* to build _only_ the `imag` binary, use the target `imag-bin`
(`imag-bin-release` for release build, `imag-bin-update` for
`cargo update`ing, `imag-bin-clean` for `cargo clean`ing).
(`imag-bin-release` for release build, `imag-bin-clean` for `cargo clean`ing).
### Running
To test out a single module, simply using `cargo run -- <options>` in the
respective directory will do the trick. For using it "normally", install the
respective directory will do the trick.
But you can also `make <module>` and call the binary on the commandline.
For using it "normally", install the
binaries as described above, as well as the imag-binary:
```
$> make install
```
The installation root of the binaries (a.k.a. where they are installed to), may
not yet be in your $PATH. To see, where this installation root is, check out
`man cargo-install`. To change the $PATH in bash:
The installation root of the binaries may not yet be in your $PATH.
To see where this installation root is check out `man cargo-install`.
To change the $PATH in bash:
```bash
$> PATH=$PATH:~/.cargo/bin
@ -155,20 +102,46 @@ To test, simply add `--help` to one of the above commands:
$> imag counter --help
```
Please note that $PATH will be reset in a new shell. To make these changes
permanent, see the User Guide of your shell.
## Staying up-to-date
Despite we have a [official site for imag](http://imag-pim.org), I do not push
updates to this site, yet. Anyways, I post a blog articles about what happened
in the last two weeks every other week.
You can find them
[on my personal blog, tagged "imag"](http://beyermatthias.de/tags/imag.html)
I also post these blog posts
[on reddit](https://www.reddit.com/r/rust/search?q=What%27s+coming+up+in+imag&restrict_sr=on)
and submit them to [this-week-in-rust](https://this-week-in-rust.org/).
From time to time I publish an article about imag which does not focus on some
things that are happening, but rather about something more general.
