+OSXPhotos
+=========
+
+What is osxphotos?
+------------------
+
+OSXPhotos provides both the ability to interact with and query Apple's Photos.app library on macOS directly from your python code 
+as well as a very flexible command line interface (CLI) app for exporting photos. 
+You can query the Photos library database -- for example, file name, file path, and metadata such as keywords/tags, persons/faces, albums, etc. 
+You can also easily export both the original and edited photos. 
+
+Supported operating systems
+---------------------------
+
+Only works on macOS (aka Mac OS X). Tested on macOS Sierra (10.12.6) until macOS Catalina (10.15.7). 
+Beta support for macOS Big Sur (10.16.01/11.01).
+
+This package will read Photos databases for any supported version on any supported macOS version.  
+E.g. you can read a database created with Photos 5.0 on MacOS 10.15 on a machine running macOS 10.12 and vice versa.
+
+Requires python >= ``3.7``. 
+
+Installation
+------------
+
+If you are new to python and just want to use the command line application, I recommend you to install using pipx. See other advanced options below. 
+
+Installation using pipx
+^^^^^^^^^^^^^^^^^^^^^^^
+
+If you aren't familiar with installing python applications, I recommend you install ``osxphotos`` with `pipx <https://github.com/pipxproject/pipx>`_. If you use ``pipx``\ , you will not need to create a virtual environment as ``pipx`` takes care of this. The easiest way to do this on a Mac is to use `homebrew <https://brew.sh/>`_\ :
+
+
+* Open ``Terminal`` (search for ``Terminal`` in Spotlight or look in ``Applications/Utilities``\ )
+* Install ``homebrew`` according to instructions at `https://brew.sh/ <https://brew.sh/>`_
+* Type the following into Terminal: ``brew install pipx``
+* Then type this: ``pipx install osxphotos``
+* Now you should be able to run ``osxphotos`` by typing: ``osxphotos``
+
+Installation using pip
+^^^^^^^^^^^^^^^^^^^^^^
+
+You can also install directly from `pypi <https://pypi.org/project/osxphotos/>`_\ :
+
+.. code-block::
+
+   pip install osxphotos
+
+
+Installation from git repository
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+OSXPhotos uses setuptools, thus simply run:
+
+.. code-block::
+
+   git clone https://github.com/RhetTbull/osxphotos.git
+   cd osxphotos
+   python3 setup.py install
+
+
+I recommend you create a `virtual environment <https://docs.python.org/3/tutorial/venv.html>`_ before installing osxphotos.
+
+**WARNING** The git repo for this project is very large (> 1GB) because it contains multiple Photos libraries used for testing 
+on different versions of macOS.  If you just want to use the osxphotos package in your own code, 
+I recommend you install the latest version from `PyPI <https://pypi.org/project/osxphotos/>`_ which does not include all the test 
+libraries. If you just want to use the command line utility, you can download a pre-built executable of the latest 
+`release <https://github.com/RhetTbull/osxphotos/releases>`_ or you can install via ``pip`` which also installs the command line app.  
+If you aren't comfortable with running python on your Mac, start with the pre-built executable or ``pipx`` as described above.
+
+Command Line Usage
+------------------
+
+This package will install a command line utility called ``osxphotos`` that allows you to query the Photos database and export photos.  
+Alternatively, you can also run the command line utility like this: ``python3 -m osxphotos``
+
+.. code-block::
+
+   > osxphotos
+   Usage: osxphotos [OPTIONS] COMMAND [ARGS]...
+
+   Options:
+     --db <Photos database path>  Specify Photos database path. Path to Photos
+                                  library/database can be specified using either
+                                  --db or directly as PHOTOS_LIBRARY positional
+                                  argument. If neither --db or PHOTOS_LIBRARY
+                                  provided, will attempt to find the library to
+                                  use in the following order: 1. last opened
+                                  library, 2. system library, 3.
+                                  ~/Pictures/Photos Library.photoslibrary
+     --json                       Print output in JSON format.
+     -v, --version                Show the version and exit.
+     -h, --help                   Show this message and exit.

+<p>OSXPhotos provides both the ability to interact with and query Apple’s Photos.app library on macOS directly from your python code
+as well as a very flexible command line interface (CLI) app for exporting photos.
+You can query the Photos library database – for example, file name, file path, and metadata such as keywords/tags, persons/faces, albums, etc.
+You can also easily export both the original and edited photos.</p>

+<h3>Installation using pipx<a class="headerlink" href="#installation-using-pipx" title="Permalink to this headline">¶</a></h3>
+<p>If you aren’t familiar with installing python applications, I recommend you install <code class="docutils literal notranslate"><span class="pre">osxphotos</span></code> with <a class="reference external" href="https://github.com/pipxproject/pipx">pipx</a>. If you use <code class="docutils literal notranslate"><span class="pre">pipx</span></code>, you will not need to create a virtual environment as <code class="docutils literal notranslate"><span class="pre">pipx</span></code> takes care of this. The easiest way to do this on a Mac is to use <a class="reference external" href="https://brew.sh/">homebrew</a>:</p>
+<ul class="simple">
+<li><p>Open <code class="docutils literal notranslate"><span class="pre">Terminal</span></code> (search for <code class="docutils literal notranslate"><span class="pre">Terminal</span></code> in Spotlight or look in <code class="docutils literal notranslate"><span class="pre">Applications/Utilities</span></code>)</p></li>
+<li><p>Install <code class="docutils literal notranslate"><span class="pre">homebrew</span></code> according to instructions at <a class="reference external" href="https://brew.sh/">https://brew.sh/</a></p></li>
+<li><p>Type the following into Terminal: <code class="docutils literal notranslate"><span class="pre">brew</span> <span class="pre">install</span> <span class="pre">pipx</span></code></p></li>
+<li><p>Then type this: <code class="docutils literal notranslate"><span class="pre">pipx</span> <span class="pre">install</span> <span class="pre">osxphotos</span></code></p></li>
+<li><p>Now you should be able to run <code class="docutils literal notranslate"><span class="pre">osxphotos</span></code> by typing: <code class="docutils literal notranslate"><span class="pre">osxphotos</span></code></p></li>

+<p>I recommend you create a <a class="reference external" href="https://docs.python.org/3/tutorial/venv.html">virtual environment</a> before installing osxphotos.</p>
+<p><strong>WARNING</strong> The git repo for this project is very large (&gt; 1GB) because it contains multiple Photos libraries used for testing
+on different versions of macOS.  If you just want to use the osxphotos package in your own code,
+I recommend you install the latest version from <a class="reference external" href="https://pypi.org/project/osxphotos/">PyPI</a> which does not include all the test
+libraries. If you just want to use the command line utility, you can download a pre-built executable of the latest
+<a class="reference external" href="https://github.com/RhetTbull/osxphotos/releases">release</a> or you can install via <code class="docutils literal notranslate"><span class="pre">pip</span></code> which also installs the command line app.
+If you aren’t comfortable with running python on your Mac, start with the pre-built executable or <code class="docutils literal notranslate"><span class="pre">pipx</span></code> as described above.</p>

+Several options, such as --directory, allow you to specify a template  which
+will be rendered to substitute template fields with values from the photo.
+For example, '{created.month}' would be replaced with the month name of the
+photo creation date.  e.g. 'November'.
+
+Some options supporting templates may be repeated e.g., --keyword-template
+'{label}'  --keyword-template '{media_type}' to add both labels and media
+types to the  keywords.
+
+The general format for a template is '{TEMPLATE_FIELD,DEFAULT}'. The full template format is: 
+'{DELIM+TEMPLATE_FIELD(PATH_SEP)[OLD,NEW]?VALUE_IF_TRUE,DEFAULT}'
+
+With a few exceptions (like '{created.strftime}') everything but the TEMPLATE_FIELD
+is optional.
+
+- 'DELIM+' Multi-value template fields such as '{keyword}' may be expanded 'in place'
+with an optional delimiter using the template form '{DELIM+TEMPLATE_FIELD}'.
+For example, a photo with  keywords 'foo' and 'bar':
+
+'{keyword}' renders to 'foo' and 'bar'
+
+'{,+keyword}' renders to: 'foo,bar'
+
+'{; +keyword}' renders to: 'foo; bar'
+
+'{+keyword}' renders to 'foobar'
+
+- 'TEMPLATE_FIELD' The name of the template field, for example 'keyword'
+
+- '(PATH_SEP)' Some template fields such as '{folder_album}' are "path-like" in 
+that they join multiple elements into a single path-like string. For example, 
+if photo is in album Album1 in folder Folder1, '{folder_album}' results in
+'Folder1/Album1'. This is so these template fields may be used as paths in
+--directory. If you intend to use such a field as a string, e.g. in the
+filename, you may specify a different path separator using the form:
+'{TEMPLATE_FIELD(PATH_SEP)}'. For example, using the example above,
+'{folder_album(-)}' would result in 'Folder1-Album1' and '{folder_album()}'
+would result in  'Folder1Album1'.
+
+- '[OLD,NEW]' Use the [OLD,NEW] option to replace text "OLD" in the template value
+with text "NEW". For example, if you have album names with '/' in the album name you
+could replace '/' with "-" using the template '{album[/,-]}'. This would replace
+any occurence of "/" in the album name with "-"; album "Vacation/2019" would thus
+become "Vacation-2019".  You may specify more than one pair of OLD,NEW values by
+listing them delimited by '|'. For example: '{album[/,-|:,-]}' to replace both
+'/' and ':' by '-'. You can also use the [OLD,NEW] syntax to delete a character by
+omitting the NEW value as in '{album[/,]}'.
+
+- '?' Some template fields such as 'hdr' are boolean and resolve to True or False.
+These take the form: '{TEMPLATE_FIELD?VALUE_IF_TRUE,VALUE_IF_FALSE}', e.g.
+{hdr?is_hdr,not_hdr} which would result in 'is_hdr' if photo is an HDR  image
+and 'not_hdr' otherwise.
+
+- ',DEFAULT' The ',' and DEFAULT value are optional.  If TEMPLATE_FIELD results
+in a null (empty) value, the template will result in default value of '_'.
+You may specify an alternate default value by appending ',DEFAULT' after
+template_field. Example: '{title,no_title}' would result in 'no_title' if the photo
+had no title. Example: '{created.year}/{place.address,NO_ADDRESS}' but there was 
+no address associated with the photo, the resulting output would be:
+'2020/NO_ADDRESS/photoname.jpg'. If specified, the default value may not
+contain a brace symbol ('{' or '}').
+
+Again, if you do not specify a default value and the template substitution has no
+value, '_' (underscore) will be used as the default value. For example, in the
+above example, this would result in '2020/_/photoname.jpg' if address was
+null.
+
+You may specify a null default (e.g. "" or empty string) by omitting the value
+after the comma, e.g. {title,} which would render to "" if title had no value thus
+effectively deleting the template from the resulting string.
+
+You may include other text in the template string outside the {}
+and use more than one template field in a single string, 
+e.g. '{created.year} - {created.month}' (e.g. '2020 - November').
+
+Some templates may resolve to more than one value.  For example, a photo can
+have multiple keywords so '{keyword}' can result in multiple values.  If used
+in a filename  or directory, these templates may result in more than one copy
+of the photo being exported.  For example, if photo has keywords "foo" and
+"bar", --directory '{keyword}' will result in  copies of the photo being
+exported to 'foo/image_name.jpeg' and 'bar/image_name.jpeg'.
+
+Some template fields such as '{media_type}' use the 'DEFAULT' value to allow
+customization  of the output. For example, '{media_type}' resolves to the
+special media type of the  photo such as 'panorama' or 'selfie'.  You may use
+the 'DEFAULT' value to override  these in form:
+'{media_type,video=vidéo;time_lapse=vidéo_accélérée}'.  In this example, if
+photo is a time_lapse photo, 'media_type' would resolve to  'vidéo_accélérée'
+instead of 'time_lapse' and video would resolve to 'vidéo' if photo is an
+ordinary video.
+
+With the --directory and --filename options you may specify a template for the
+export directory or filename, respectively. The directory will be appended to
+the export path specified in the export DEST argument to export. For example,
+if template is '{created.year}/{created.month}', and export destination DEST
+is '/Users/maria/Pictures/export', the actual export directory for a photo
+would be '/Users/maria/Pictures/export/2020/March' if the photo was created in
+March 2020.
+
+The templating system may also be used with the --keyword-template option to
+set keywords on export (with --exiftool or --sidecar), for example, to set a
+new keyword in format 'folder/subfolder/album' to preserve the folder/album
+structure, you can use --keyword-template "{folder_album}"
+
+In the template, valid template substitutions will be replaced by the
+corresponding value from the table below.  Invalid substitutions will result
+in an error.
+
+If you want the actual text of the template substition to appear in the
+rendered name, use double braces, e.g. '{{' or '}}', thus using
+'{created.year}/{{name}}' for --directory would result in output of
+2020/{name}/photoname.jpg
