 # libcifpp
 
-This library contains code to work with mmCIF and legacy PDB files.
+As the name implies, this library was originally written to work with mmCIF files
+using C++ as programming language. The design of this library leanes heavily on
+the structure of CIF files. These files can be thought of as a text dump of a
+relational databank with, often but not always, a very strict schema describing
+the data. These schema's are called dictionaries.
+
+Using information from the content of a mmCIF file and an optional schema,
+libcifpp allows you to access the data in the file as a collection of datablock
+each containing a collection of categories with rows of data. The categories can
+be searched for data using queries written in regular C++ syntax. When a dictionary
+was specified, inserted data is checked for validity. Likewise removal of data
+may result in cascaded removal of linked data in other categories using
+parent/child relationship information.
+
+Since there were still many programs using the legacy PDB format at the time
+development started, a layer was added that converts data to and from PDB format
+into mmCIF format. This means you can manipulate PDB files as if they were
+normal mmCIF files.
+
+Apart from this basic functionality, libcifpp also offers code to help with
+symmetry calculations, 3d manipulations and obtaining information from the CCD
+[Chemical Component Dictionary](https://www.wwpdb.org/data/ccd).

 You might be able to use libcifpp from a package manager used by your

 Therefore it is recommended to build *libcifpp* from code. It is not
-hard to do.
+hard to do. But it is recommended to read the following instructions
+carefully.
 
 ### Requirements
 
 The code for this library was written in C++17. You therefore need a
-recent compiler to build it. For the development gcc 9.4 and clang 9.0
+recent compiler to build it. For the development gcc >= 9.4 and clang >= 9.0
 have been used as well as MSVC version 2019.
 
-Other requirements are:
+The other requirement you really need to have installed on your computer
+is a version of [CMake](https://cmake.org). For now the minimum version
+is 3.16 but that may soon change into a higher version. You should also
+install the gui version of CMake to set build options easily, on Debian
+I prefer to use the curses version installed with `cmake-curses-gui`.
+
+It is very useful to have [mrc](https://github.com/mhekkel/mrc) available.
+However, this is only an option if you use Windows or an operating system
+using the ELF executable format (i.e. Linux or FreeBSD). MRC is a resource
+compiler that allows including data files into the executable making them
+easier to install.
+
+Other libraries you might want to install beforehand are:
 
-- [cmake](https://cmake.org) A build tool.
-- [mrc](https://github.com/mhekkel/mrc), a resource compiler that
-  allows including data files into the executable making them easier to
-  install. Strictly speaking this is optional, but at the expense of
-  functionality.
 - [libeigen](https://eigen.tuxfamily.org/index.php?title=Main_Page), a
   library to do amongst others matrix calculations. This usually can be
   installed using your package manager, in Debian/Ubuntu it is called
   `libeigen3-dev`
-- zlib, the development version of this library. On Debian/Ubuntu this
-  is the package `zlib1g-dev`.
-- [boost](https://www.boost.org).
-
-When building using MS Visual Studio, you will also need [libzeep](https://github.com/mhekkel/libzeep)
-since MSVC does not yet provide a C++ template required by libcifpp.
-
-The Boost libraries are only needed in case you want to build the test
-code or if you are using GCC. That last condition is due to a long
-standing bug in the implementation of std::regex. It simply crashes
-on the regular expressions used in the mmcif_pdbx dictionary and so
-we use the boost regex implementation instead.
+- [zlib](https://github.com/madler/zlib), the development version of this
+  library. On Debian/Ubuntu this is the package `zlib1g-dev`.
+- [pcre2](https://www.pcre.org/), the Perl Compatible Regular Expression
+  library. On Debian/Ubuntu this is the package `libpcre2-dev`.
 
 ### Building
 
-Building the code is as simple as typing:
+First you need to download the code:
 
 ```console
- git clone https://github.com/PDB-REDO/libcifpp.git --recurse-submodules
+ git clone https://github.com/PDB-REDO/libcifpp.git
  cd libcifpp
- cmake -S . -B build -DCMAKE_INSTALL_PREFIX=$HOME/.local -DCMAKE_BUILD_TYPE=Release
- cmake --build build
- cmake --install build
 ```
 
-This checks out the source code from github, creates a new directory
-where cmake stores its files. Run a configure, build the code and then
-it installs the library and auxiliary files.
+You should start by considering where to install libcifpp. If you have
+sufficient permissions on your computer you perhaps should use the
+default but libcifpp can be configured to be installed anywhere
+including e.g. *$HOME/.local*.
+
+Next step is to configure, for this use the CMake gui application. If you
+installed the curses version of cmake you can type `ccmake`. On Windows
+you can use `cmake-gui.exe`.
+
+To install in the default location:
+
+```console
+ccmake -S . -B build
+```
+
+To install elsewhere, e.g. *$HOME/.local*:
+
+```console
+ccmake -S . -B build -DCMAKE_INSTALL_PREFIX=$HOME/.local
+```
+
+In the cmake window, start the configure command (use button or press 'c').
+After the first configure step you will see a list of settable options.
+Alter these to match your preferences. Most options are self explaining
+and contain a description. Some may need a bit more explanation:
+
+- CIFPP_DATA_DIR, this directory will be used to store initial versions
+  of the mmcif_pdbx dictionary as well as the optional CCD file.
+
+- CIFPP_DOWNLOAD_CCD
+
+  The CCD file is huge and perhaps you think you don't
+  need it. In that case you can leave this OFF. But that will limit the
+  use cases.
+
+- CIFPP_INSTALL_UPDATE_SCRIPT
+  
+  The files in CIFPP_DATA_DIR are quickly becoming out of date. On
+  FreeBSD and Linux you can install a script that updates these files
+  on a weekly basis.
+
+- CIFPP_CRON_DIR
+  
+  The directory where the update script is to be installed.
+
+- CIFPP_ETC_DIR
+  
+  The update script will only work if the file called *libcifpp.conf*
+  in this *etc* directory will contain an uncommented line with
+
+```console
+update=true
+```
+
+- CIFPP_CACHE_DIR
+
+  When you installed and enabled the update script, new files are
+  written to this directory.
+
+- CIFPP_RECREATE_SYMOP_DATA
+  
+  If you had CCP4 sourced into your environment, this option allows
+  you to recreate the symop data file.
+
+- BUILD_FOR_CCP4
+  
+  Build a special version of libcifpp to be installed in the CCP4
+  environment.
+
+After setting these options you can run the configure step again and
+then use generate to create the makefiles.
+
+Building and installing is then as simple as:
+
+```console
+cmake --build build
+cmake --install build
+```
+
+If this fails due to lack of permissions, you can try:
+
+```console
+sudo cmake --install build
+```
 
 Tests are created by default, and to test the code you can run:
 
 ```console
- cmake --build build
- ctest --test-dir build
+ctest --test-dir build
 ```

+CQL
+===
+
+The structure of cif files (even of STAR files, from which this format is derived) looks suspiciously like a relational database. When you consider categories to be tables and items to be columns you're almost there. The only problem is linking tables, in common cif files this is done based on multiple columns and the rules are a bit fuzzy allowing for empty columns to still match related columns that do have a value.
+
+An early version of the tool *mmCQL* contained a SQL like language interpreter to SELECT and UPDATE values in cif files. This functionality has been expanded by implementing a full SQL interface using the `SQLite <https://sqlite.org>`_ library. Libcifpp categories are exposed as virtual tables in a SQLite environment and can be queried and manipulated using SQL syntax.
+
+The current limitation is that CREATE TABLE and ALTER TABLE are not supported yet. Since SQLite has no way of supporting this, we will have to write a preprocessor to intercept these statements. That's on the to-do list.
+
+The new *mmcql* tools in `cif-tools <https://github.com/PDB-REDO/cif-tools>`_ uses this new backend and is a command line application you can use similar to the *sqlite* or e.g. *psql* tools for regular SQLite files and postgresql databanks respectively.
+
+Synopsis
+--------
+
+.. literalinclude:: ../examples/example-cql.cpp
+	:language: c++
+	:start-at: #include <cif++/cif++.hpp>
+
+Usage
+-----
+
+To start using CQL, you will first have to create a :cpp:class:`connection` to a :cpp:class:`cif::cql::datablock`. Using this connection you can create a :cpp:class:`transaction`. And with the transaction can execute SQL statements using :cpp:func:`cif::cql::transaction::exec`. Or you can use the :cpp:func:`cif::cql::transaction::stream` function to directly pull values from the result.
+
+The result of :cpp:func:`cif::cql::transaction::exec` is a :cpp:class:`cif::cql::result` class which uses a :cpp:class:`cif::category` as storage class.
+
+Implementation Details
+----------------------
+
+When the datablock contains a validator (i.e. you loaded a dictionary) the SQL engine knows about all possible items/columns that are allowed. It also knows about links/relations between categories, just like the regular libcifpp query mechanism. So, updating and deleting will cascade automatically.
+
+Another point is data types. cif files can have numbers, strings or NULL values. Same goes for SQLite. However, when a file was loaded without a dictionary, the type of an item is dependent on its content. If something was parsed as being a number, the type will be numeric. If however, the file does contain a dictionary/validator, the type is determined by this dictionary. So, even if it looks like a number, it still might be a string internally. Good example is the ID field in atom_site, or the auth_seq_id/auth_seq_num fields. In the WHERE clause this may have unexpected results, so you may have to fall back to using `CAST <https://sqlite.org/lang_expr.html#castexpr>`_.
+
+The API for this functionality is a bit new, there may be room for improvement. Ideas are welcome.

- * @brief A stripped down quaternion implementation, based on boost::math::quaternion
- *
- * We use quaternions to do rotations in 3d space. Quaternions are faster than

- * errors.
- *
- * Like complex number, quaternions do have a meaningful notion of "real part",
- * but unlike them there is no meaningful notion of "imaginary part".
- * Instead there is an "unreal part" which itself is a quaternion, and usually
- * nothing simpler (as opposed to the complex number case).
- * However, for practicality, there are accessors for the other components
- * (these are necessary for the templated copy constructor, for instance).
- *
- * @note Quaternion multiplication is *NOT* commutative;
- * symbolically, "q *= rhs;" means "q = q * rhs;"
- * and "q /= rhs;" means "q = q * inverse_of(rhs);"

+ *
  * You can access the values of stored items by name or index.
- * The return value of operator[] is an cif::item_handle object.

+ *
  * There some template magic here to allow easy extracting of data
  * from rows. This can be done using cif::tie e.g.:
- * 
+ *
  * @code {.cpp}
  * std::string name;
  * float x, y, z;

+ *
  * cif::tie(name, x, y, z) = rh.get("label_atom_id", "cartn_x", "cartn_y", "cartn_z");
  * @endcode
- * 
+ *
  * However, a more modern way uses structured binding:
- * 
+ *
  * @code {.cpp}
  * const auto &[name, x, y, z] = rh.get<std::string,float,float,float>("label_atom_id", "cartn_x", "cartn_y", "cartn_z");

  * @brief A simple progress bar class for terminal based output
- * 
+ *
  * Using a progress bar is very convenient for the end user when
  * you have long running code. It gives feed back on how fast an
  * operation is performed and may give an indication how long it
  * will take before it is finished.
- * 
+ *
  * Using this cif::progress_bar implementation is straightforward:
- * 
+ *
  * @code {.cpp}
  * using namespace std::chrono_literals;
- * 
+ *
  * cif::progress_bar pb(10, "counting to ten");
- * 
+ *
  * for (int i = 1; i <= 10; ++i)
  * {
  *   pb.consumed(1);
  *   std::this_thread::sleep_for(1s);
  * }
- * 
+ *
  * @endcode
- * 
+ *
  * When the progress_bar is created, it first checks
  * to see if stdout is to a real TTY and if the VERBOSE
  * flag is not less than zero (quiet mode). If this passes
  * a thread is started that waits for updates.
- * 
+ *
  * The first two seconds, nothing is written to the screen
  * so if the work is finished within those two seconds
  * the screen stays clean.
- * 
+ *
  * After this time, a progress bar is printed that may look
  * like this:
- * 
+ *
  * @code
  * step 3           ========================--------------------------------  40% ⢁
  * @endcode
- * 
+ *
  * The first characters contain the initial action name or
  * the message text if it was used afterwards.
- * 
+ *
  * The thermometer is made up with '=' and '-' characters.
- * 
+ *
  * A percentage is also shown and at the end there is a spinner
  * that gives feedback that the program is really still working.
- * 
+ *
  * The progress bar is removed if the max has been reached
  * or if the progress bar is destructed. If any output has
  * been generated, the initial action is printed out along

-Boost Regex Library
-============================
-
-The Boost Regex library provides regular expression support for C++, this library is the ancestor to std::regex and still goes beyond
-and offers some advantages to, the standard version.
-
-The full documentation is available on [boost.org](http://www.boost.org/doc/libs/release/libs/regex/index.html).
-
-## Standalone Mode ##
-
- This library may now be used in "standalone" mode without the rest of the Boost C++ libraries, in order to do this you must either:
-
-* Have a C++17 compiler that supports __has_include, in this case if <boost/config.hpp> is not present then the library will automoatically enter standalone mode. Or:
-* Define BOOST_REGEX_STANDALONE when building.
-
-The main difference between the 2 modes, is that when Boost.Config is present the library will automatically configure itself around various compiler defects. In particular in order to use the library with exception support turned off, you will either need a copy of Boost.Config in your include path, or else manually define BOOST_NO_EXCEPTIONS when building.
-
-In any event, to obtain a standalone version of this library, simply download a .zip of the "master" branch of this repository.
-
-## Support, bugs and feature requests ##
-
-Bugs and feature requests can be reported through the [Gitub issue tracker](https://github.com/boostorg/regex/issues)
-(see [open issues](https://github.com/boostorg/regex/issues) and
-[closed issues](https://github.com/boostorg/regex/issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aclosed)).
-
-You can submit your changes through a [pull request](https://github.com/boostorg/regex/pulls).
-
-There is no mailing-list specific to Boost Regex, although you can use the general-purpose Boost [mailing-list](http://lists.boost.org/mailman/listinfo.cgi/boost-users) using the tag [regex].
-
-
-## Development ##
-
-Clone the whole boost project, which includes the individual Boost projects as submodules ([see boost+git doc](https://github.com/boostorg/boost/wiki/Getting-Started)): 
-
-    git clone https://github.com/boostorg/boost
-    cd boost
-    git submodule update --init
-
-The Boost Regex Library is located in `libs/regex/`. 
-
-### Running tests ###
-First, make sure you are in `libs/regex/test`. 
-You can either run all the tests listed in `Jamfile.v2` or run a single test:
-
-    ../../../b2                        <- run all tests
-    ../../../b2 regex_regress          <- single test
