Sequence Editor

Aerie sequence editor is a web application with various features (auto complete, linting, hinting) to assist users while typing a sequence of commands. Aerie only supports AMPCS command dictionary schema for commands. To be able to author or edit a sequence, users must reference a command dictionary available in the Aerie instance. To upload a command dictionary see instructions here.

Navigate to the Aerie sequence editor from the Aerie drop down menu at the upper left corner.

Use main Aerie drop down menu to navigate to the Aerie sequence editor.

The landing page lists all sequences available at this venue in the left panel. Upon click users can view the contents of sequences in the right hand side editor in a "read only" mode. To edit an individual sequence click the pencil icon for the sequence on the left hand side panel as shown in the image below.

The landing page lists all sequences that are authored.

note

Currently Aerie sequence editor does not support user roles and permissions, hence all sequences authored in this venue will be accessible to everyone who has access to Aerie. User roles will allow limiting edit and/or view access to some sequences. For now, we recommend pre-appending a user name to your sequence names to indicate ownership.

In the sequence editing page users need to select a command dictionary before they can edit the sequence. Editing sequence simply means adding any of the step types defined in the seqJSON format to the steps section of the sequence. In addition seqJSON allows arbitrary JSON objects to be added as metadata. Refer to your mission guidelines regarding metadata format expected by downstream processes and tools.

Users can rename or edit a sequence, and view the seqJSON output.

Import / export seqJSON

Aerie editor allows authoring and viewing sequences in a user friendly format which is more compact, easier to read and write compared to the seqJSON. However seqJSON is the exchange format that should be used to exchange sequences with upstream and downstream tools. While creating a new sequence, users can import a seqJSON using the in (Choose File) button available at the new sequence the left panel. After authoring a sequence, it can be downloaded to the your local machine using the (Download) button at the upper right corner of the seqJSON view panel at the bottom.

Typing commands

As explained earlier authoring a sequence simply means concatenating commands in the steps array. Example below illustrates how a simple sequence with a few commands and various time tags looks like.

R001T00:00:01 GROW_BANANA 1 60
C PICK_BANANA

C AVS_RESET_ECE
C BC_MANAGE_ACTIVE_BUS "BUS_A" "DISABLE"
A2024-123T00:00:00 PACKAGE_BANANA 0 ["lot_0" 1]
R00:00:10 THROW_BANANA 10

• Each command step must start with a time tag. Time tags supported in seqJSON are command complete ( C ), absolute ( A2020-001T00:00:00), relative ( R00:00:00 ), and epoch relative (E00:00:00). To understand how these time tags get executed on board, refer to your missions Sequencing FDD.
• To view list of commands, type a time tag and a space.
• To filter commands, start typing the first few letters of the command stem.
• After selecting the command the parameters will be inside of the right "Selected Command" panel.
• If command has arguments they will be deliniated with a space.
• Editor can autocomplete argument names with the control + Space shortcut.
• For the enumerated args, control + Space can be used to select one of the defined enum values.
• Errors will be linted with a red squiggly underline. Hovering over the error should provide explanation for the error as shown below.
• Generate seqJSON will fail if you have errors in the sequence.
