+! title		Non Session Management API
+! author	Jonathan Moore Liles #(email,male@tuxfamily.org)
+! date		August 1, 2010
+
+-- Table Of Contents
+
+: Non Session Management API version 0.7
+
+  The Non Session Management API is an API for session management used
+  by the various parts of the Non music production suite. It comprises
+  a simple OSC based protocol which can easily be implemented by other
+  applications. NSM provides robust session management, including
+  interactive features.
+
+  The Non project contains an implementation of the NSM server API
+  called `nsmd` which can be controlled by the `non-session-manager`
+  GUI, but the same server API can easily be implemented by other
+  session managers (such as LADISH).
+  
+  The only dependency for clients `liblo` (the OSC library), which
+  several Linux audio applications already link to or plan to link to
+  in the future.
+
+  The aim of this project is to thoroughly define the behavior
+  required of clients. This is an area where other attempts at session
+  management (LASH and JACK-Session) have failed. Often the difficulty
+  with these previous system been, not in implementing support for
+  them, but in attempting to interpret the confusing and ambiguous API
+  documentation. For this reason, all LASH support has been removed
+  from Non.
+
+  You *WILL* see a lot of unambiguous language in this document. These
+  rules are meant to be followed and are non-negotiable. If an
+  application does not conform to this specification it should be
+  considered broken. Consistency across applications under session
+  management is very important for a good user experience.
+
+:: Client Behavior Under Session Management
+
+  Most graphical applications make available to the user a common set
+  of file operations, typically presented under a File or Project
+  menu.
+
+  These are: New, Open, Save, Save As, Close and Quit or Exit.
+
+  The following sub-sections describe how these options should behave when
+  the application is part of an NSM session. These rules only apply
+  when session management is active (that is, after the `announce`
+  handshake described in the #(ref,NSM OSC Protocol) section). 
+  
+  In order to provide a consistent and predictable user experience, it
+  is important for applications to adhere to these guidelines.
+
+::: New
+
+  This option may empty\/reset the current file or project (possibly
+  after user confirmation). *UNDER NO CIRCUMSTANCES* should it allow
+  the user to create a new project\/file in another location.
+
+::: Open
+
+  This option should be disabled. 
+
+  The application may, however, elect to implement an option called
+  'Import into Session', creates a copy of a file\/project which is
+  then saved in the session path provided by NSM.
+
+::: Save
+
+  This option should behave as normal, saving the current
+  file\/project as established by the NSM `open` message.
+
+  *UNDER NO CIRCUMSTANCES* should this option present the user with a
+  choice of where to save the file!
+
+::: Save As
+
+  This option should be disabled.
+
+  The application may, however, elect to implement an option called
+  'Export from Session', which creates a copy of the current
+  file\/project which is then saved in a user-specified location
+  outside of the session path provided by NSM.
+
+::: Close (as distinguished from Quit or Exit)
+  
+  This option should be disabled, unless its meaning is to disconnect
+  the application from session management.
+
+::: Quit or Exit
+
+  This option may behave as normal (even possibly asking the user to
+  confirm exiting).
+
+:: NSM OSC Protocol
+
+  All message parameters are *REQUIRED*. All messages *MUST* be sent
+  from the same socket as the `announce` message, using the
+  `lo\_send\_from` method of liblo (the server uses the return
+  addresses to distinguish between clients).
+
+::: Establishing a Connection
+
+:::: Announce
+
+  When started clients *MUST* check the environment for the value of
+  `NSM\_URL`. If present, the client *MUST* send the following message
+  to the provided address as soon as it is ready to respond to the
+  `\/nsm\/client\/open` event:
+
+> /nsm/server/announce s:application_name s:capabilities i:api_version_major i:api_version_minor i:pid
+
+  If `NSM\_URL` is undefined, invalid, or unreachable, then the client
+  should proceed assuming that session management is unavailable.
+
+  `api\_version\_major` and `api\_version\_minor` must be the two parts of
+  the version number of the NSM API as defined by this document.
+
+  Note that if the application intends to register JACK clients,
+  `application\_name` *MUST* be the same as the name that would
+  normally by passed to `jack\_client\_open`. For example, Non-Mixer
+  sends "Non-Mixer" as its `application\_name`. Applications *MUST
+  NOT* register their JACK clients until receiving an `open` message;
+  the `open` message will provide a unique client name prefix suitable
+  for passing to JACK. This is probably the most complex requirement
+  of the NSM API, but it isn't difficult to implement.
+
+  `capabilities` *MUST* be a string containing a colon separated list
+  of the special capabilities the client
+  possesses. e.g. ":dirty:switch:progress:"
+
+// Available Client Capabilities
+[[ Name, Description
+[[ switch, client is capable of responding to multiple `open` messages without restarting
+[[ dirty, client knows when it has unsaved changes
+[[ progress, client can send progress updates during time-consuming operations
+[[ status, client can send textual status updates 
+
+:::: Response
+
+  The server will respond to the client's `announce` with the following message:
+
+> /reply "/nsm/server/announce" s:message s:name_of_session_manager s:capabilities
+
+  `message` is a welcome message.
+
+  The value of `name\_of\_session\_manager` will depend on the
+  implementation of the NSM server. It might say "Non Session Manager",
+  or it might say "LADISH".
+
+  `capabilities` will be a string containing a colon separated list of
+  special server capabilities.
+
+  Presently, the server `capabilities` are:
+
+// Available Server Capabilities
+[[ Name, Description
+[[ server_control, client-to-server control
+
+  A client should not consider itself to be under session management
+  until it receives this response (the Non programs activate their
+  "SM" blinkers at this time.)
+
+  If there is an error, a reply of the following form will be sent to
+  the client:
+
+> /error "/nsm/server/announce" i:error_code s:error_message
+
+  The following table defines possible values of `error\_code`:
+
+// Response codes
+[[ Code, Meaning
+[[ ERR_GENERAL, General Error
+[[ ERR_INCOMPATIBLE_API, Incompatible API version
+[[ ERR_BLACKLISTED, Client has been blacklisted.
+
+::: Server to Client Control Messages
+
+  Compliant clients *MUST* accept the client control messages
+  described in this section. All client control messages *REQUIRE* a
+  response. Responses *MUST* be delivered back to the sender (NSM)
+  from the same socket used by the client in its `announce` message
+  (by using `lo\_send\_from`) *AFTER* the action has been completed or
+  if an error is encountered. The required response is described in
+  the subsection for each message.
+
+  If there is an error and the action cannot be completed, then
+  `error\_code` *MUST* be set to a valid error code (see #(fig,Error Code Definitions))
+  and `message` to a string describing the problem (suitable
+  for display to the user).
+
+  The reply can take one of the following two forms, where `path` *MUST* be
+  the path of the message being replied to (e.g. "/nsm\/client\/save"):
+
+> /reply s:path s:message
+
+> /error s:path i:error_code s:message
+
+:::: Quit
+
+  There is no message for this. Clients will receive the Unix SIGTERM
+  signal and *MUST* close cleanly *IMMEDIATELY*, without displaying
+  any kind of dialog to the user and regardless of whether or not
+  unsaved changes would be lost (when a session is closed the
+  application will receive this signal soon after having responded to
+  a `save` message).
+
+:::: Open 
+
+> /nsm/client/open s:path_to_instance_specific_project s:client_id
+
+  The client *MUST* open an existing project, or create new one if one
+  doesn't already exist, at `path\_to\_instance_specific\_project`
+
+  If the path provided doesn't exist, then the client *MUST*
+  immediately create and open a new file\/project at the specified
+  path (whether that means creating a single file or a project
+  directory).
+
+  No file or directory will be created at the specified path by the
+  server. It is up to the client to create what it needs.
+
+  The client may append to the path, creating a subdirectory,
+  e.g. '/song.foo' or simply append the client's native file extension
+  (e.g. '.non' or '.XML'). The same transformation *MUST* be applied
+  to the name when opening an existing project, as NSM will only
+  provide the instance specific part of the path.
+
+  For clients which *HAVE NOT* specified the 'switch' capability, the
+  `open` message will only be delivered once, immediately after the
+  'announce' response.
+
+  For client which *HAVE* specified the `:switch:` capability, the
+  client *MUST* immediately switch to the specified project or create
+  a new one if it doesn't exist.
+
+  Clients which are incapable of switching projects or are prone to
+  crashing upon switching *MUST NOT* include `:switch:` in their
+  capability string.
+
+  If the user the is allowed to run two or more instances of the
+  application simultaneously (that is to say, there is no technical
+  limitation preventing them from doing so, even if it doesn't make
+  sense to the author), then such an application *MUST* prepend the
+  provided `client\_id` string to any names it registers with common
+  subsystems (e.g. JACK client names). This ensures that the multiple
+  instances of the same application can be restored in any order
+  without scrambling the JACK connections or causing other
+  conflicts. The provided `client\_id` will be a concatenation of the
+  value of `application\_name` sent by the client in its `announce`
+  message and a unique identifier. Therefore, applications which
+  create single JACK clients can use the value of `client\_id` directly
+  as their JACK client name. Applications which register multiple JACK
+  clients (e.g. Non-Mixer) *MUST* prepend `client_id` value to the
+  client names they register with JACK and the application determined
+  part *MUST* be unique for that (JACK) client.
+
+  For example, a suitable JACK client name would be:
+
+> $CLIENT_ID/track-1
+
+  A response is *REQUIRED* *AFTER* the load\/new operation has been
+  completed.  Ongoing progress may be indicated by sending messages to
+  `\/nsm\/client\/progress`.
+
+::::: Response
+
+  The client *MUST* respond to the 'open' message with:
+
+> /reply "/nsm/client/open" s:message
+
+  Or
+
+> /error "/nsm/client/open" i:error_code s:message
+
+// Response Codes
+[[ Code, Meaning
+[[ ERR, General Error
+[[ ERR_BAD_PROJECT, An existing project file was found to be corrupt
+[[ ERR_CREATE_FAILED, A new project could not be created
+[[ ERR_UNSAVED_CHANGES, Unsaved changes would be lost
+[[ ERR_NOT_NOW, Operation cannot be completed at this time
+
+:::: Save
+
+> /nsm/client/save
+
+  The client *MUST* immediately save the current application specific
+  project data to the project path previously established in the
+  'open' message. *UNDER NO CIRCUMSTANCES* should a dialog be
+  displayed to the user (giving a choice of where to save, etc.)
+

+  The client *MUST* respond to the 'save' message with:
+
+> /reply "/nsm/client/save" s:message
+
+  Or
+
+> /error "/nsm/client/save" i:error_code s:message
+
+// Response Codes
+[[ Code, Meaning
+[[ ERR, General Error
+[[ ERR_SAVE_FAILED, Project could not be saved
+[[ ERR_NOT_NOW, Operation cannot be completed at this time
+
+::: Server to Client Informational Messages
+
+:::: Session is Loaded
+ 
+  Accepting this message is optional. The intent is to signal to
+  clients which may have some interdependency (say, peer to peer OSC
+  connections) that the session is fully loaded and all their peers
+  are available.
+
+> /nsm/client/session_is_loaded
+
+  This message does not require a response.
+
+::: Client to Server Informational Messages
+
+  These are optional messages which a client can send to the NSM
+  server to inform it about the client's status. The client should not
+  expect any reply to these messages. If a client intends to send a
+  message described in this section, then it *MUST* add the
+  appropriate value to its `capabilities` string when composing the
+  `announce` message.
+
+:::: Progress
+
+> /nsm/client/progress f:progress
+
+  For potentially time-consuming operations, such as `save` and
+  `open`, progress updates may be indicated throughout the duration by
+  sending a floating point value between 0.0 and 1.0, 1.0 indicating
+  completion, to the NSM server.
+
+  The server will not send a response to these messages, but will
+  relay the information to the user.
+
+  Note that, even when using the `progress` feature, the final
+  response to the `save` or `open` message is still *REQUIRED*.
+
+  Clients which intend to send `progress` messages should include
+  `:progress:` in their `announce` capability string.
+
+:::: Dirtiness
+
+> /nsm/client/is_dirty
+
+> /nsm/client/is_clean
+
+  Some clients may be able to inform the server when they have unsaved
+  changes pending. Such clients may optionally send `is\_dirty` and `is\_clean`
+  messages. 
+
+  Clients which have this capability should include `:dirty:` in their
+  `announce` capability string.
+
+:::: Status Messages
+
+> /nsm/client/message i:priority s:message
+
+  Clients may send miscellaneous status updates to the server for
+  possible display to the user. This may simply be chatter that is normally
+  written to the console. `priority` should be a number from 0 to 3, 3
+  being the most important.
+
+  Clients which have this capability should include `:message:` in their
+  `announce` capability string.
+
+::: Error Code Definitions
+
+// Error Code Definitions
+[[ Symbolic Name, Integer Value
+[[ ERR_GENERAL, -1
+[[ ERR_INCOMPATIBLE_API, -2
+[[ ERR_BLACKLISTED,      -3
+[[ ERR_LAUNCH_FAILED,    -4
+[[ ERR_NO_SUCH_FILE,     -5
+[[ ERR_NO_SESSION_OPEN, -6
+[[ ERR_UNSAVED_CHANGES,  -7
+[[ ERR_NOT_NOW, -8
+[[ ERR_BAD_PROJECT, -9
+[[ ERR_CREATE_FAILED, -10
+
+::: Client to Server Control
+
+  If the server publishes the `server\_control` capability, then
+  clients can also initiate action by the server. For example, a
+  client might implement a 'Save All' option which sends a
+  `\/nsm\/server\/save` message to the server, rather than requiring
+  the user to switch to the session management interface to effect the
+  save.
+
+::: Server Control API
+
+  The session manager not only manages clients via OSC, but it is itself
+  controlled via OSC messages. The server responds to the following
+  messages.
+
+  All of the following messages will be responded to back to the sender's address 
+  with one of the two following messages:
+
+> /reply s:path s:message
+
+> /error s:path i:error_code s:message
+ 
+  The first parameter of the reply is the path to the message being
+  replied to. The `\/error` reply includes an integer error code
+  (non-zero indicates error). `message` will be a description of the
+  error.
+
+  The possible errors are:
+
+// Responses
+[[ Code, Meaning
+[[ ERR_GENERAL, General Error
+[[ ERR_LAUNCH_FAILED, Launch failed
+[[ ERR_NO_SUCH_FILE, No such file
+[[ ERR_NO_SESSION, No session is open
+[[ ERR_UNSAVED_CHANGES, Unsaved changes would be lost
+
+= /nsm/server/add s:path_to_executable
+  Adds a client to the current session.
+
+= /nsm/server/save
+  Saves the current session.
+
+= /nsm/server/load s:project_name
+  Saves the current session and loads a new session.
+
+= /nsm/server/new s:project_name
+  Saves the current session and creates a new session.
+
+= /nsm/server/close
+  Saves and closes the current session.
+
+= /nsm/server/abort
+  Closes the current session *WITHOUT SAVING*  
+
+= /nsm/server/quit
+  Saves and closes the current session and terminates the server.
+
+= /nsm/server/duplicate s:new_project 
+  Saves and closes the current session, creates a complete copy of
+  it as `new_project` and opens it. The existing project should ideally be
+  a lightweight template, as copying any audio data could be very time
+  consuming.
+
+= /nsm/server/list 
+  Lists available projects. One `\/reply` message will be sent for each existing project.
+
+
+
+# = /nsm/server/client/list
+#   Lists clients in the current session, their client IDs and statuses
+# = /nsm/server/ve
+
+:::: Client to Client Communication
+
+  If the server includes `:broadcast:` in its capability string, then
+  clients may send broadcast messages to each other through the NSM
+  server.
+  
+  Clients may send messages to the server at the path
+  `\/broadcast`.
+
+  The format of this message is as follows:
+
+> /nsm/server/broadcast s:path [other parameters...]
+
+  The message will then be relayed to all clients in the session at
+  the path given in the `path` parameter and with the other parameters
+  shifted forward by one.
+
+  For example the message:
+
+>  /nsm/server/broadcast /tempomap/update "0,120,4/4:12351234,240,4/4"
+
+  Would broadcast the following message to all clients in the session
+  (except for the sender), some of which might respond to the message
+  by updating their own tempo maps.
+
+>  /tempomap/update "0,120,4/4:12351234,240,4/4"
+
+  Clients may use this feature to establish peer to peer OSC
+  communication with symbolic names without having to remember the OSC
+  URLs of peers.
