Instructions

If you don't know what the Septic file format is, then you don't need this extension.

Adding the Septic extension to VS Code allows you to do the following when loading a Septic .cnfg file:

• Auto-complete for references to other objects (identifiers and attributes), object attributes and calcs.

• Diagnose certain fault modes (missing parenthesis in calcs, mistyped Calc or Xvr names etc.)

• Auto-complete commonly used segments of code, called snippets

  • Type e.g. 'sopc' (uncapitalized letters only), and you should see a number of sopcxvr snippet options. Choose the one you want with arrow up/arrow down and press Tab to create a complete sopcxvr section.
  • If you are missing a snippet, let us know and we will add it. Feel free to make one yourself and provide us the json.
  • More info on snippets here

• Fold sections of the config file. Either click the small downward-pointing arrows in the gutter to fold a specific section and all its lower-level sections, or use the following shortcuts to fold and unfold sections at different levels:

  • ctrl-k ctrl-0 folds everything.
  • ctrl-k ctrl-j unfolds everything.
  • ctrl-k ctrl-k folds/unfolds the region at the cursor.
  • ctrl-k ctrl-1 folds all level 1 sections (e.g. SopcProc and System) and lower except the level 1 section at the cursor.
  • ctrl-k ctrl-2 folds all level 2 sections (e.g. SopcMvr and CalcModl) and lower except the level 2 section at the cursor.
  • ctrl-k ctrl-3 folds all level 3 sections (e.g. CalcPvr) and lower except the level 3 section at the cursor.
  • More info on folding here

• Diagnostics (Errors/Warnings) for a certain line can be disabled by writing // noqa or {# noqa #} at the same line. It is recommended to use the jinja version when suppressing diagnostics when using scg in order to get proper diagnostics on the generated config. To disable certain errors/warnings write {# noqa: Ennn, Wnnn #} or // noqa: Ennn, Ennn (i.e. noqa + : + comma separated list of errors). The relevant error codes are displayed on the errors/warnings (e.g. septic Enn). To disable all diagnostics, use the septic.diagnostics.enabled setting. Diagnostics can be ignored for certain files by adding the path of the file to the septic.ignored.paths setting together with an array with the specific codes that should be ignored. Empty array is interpreted as ignore all codes. * can be used as a wildcard i.e. you can write templates/* to ignore all files in the folder templates. Examples: "templates_sim/Sopc*": [] will ignore all diagnostics from files that matches the pattern, "/templates_main/SmpcAppl.cnfg": ["W501"] will ignore all diagnostics with code W501. The paths are calculated relative the workspace folder(s) root(s) i.e. templates/*, /templates/* and ./templates/* are equivalent. This setting should be set on a workspace level in order avoid unintentionally ignoring files when switching between projects.

  • Code actions for adding comment that disables diagnostics for a certain code is available. The code action is only available if there are no non-disable-diagnostics comments on the same line, and will either insert a new comment or update existing disable comment.

• Formatting of cnfg files can be enabled by setting septic.formatting.enabled = True in the settings. Comments // or /* */ and jinja-comments {# #} are not formatted. Everything between the jinja expressions {% for w %} ... {% endfor %} and {% if %} ... {% endif %} are not formatted. To avoid formatting certain sections of the file the flags {# format:off #} and {# format:on #} can be used to turn off and on again formatting (Tip: snippets available by writing formaton/off).

• Documentation of objects and calcs are available by hovering over the object/calc definition. Hovering on object definition will provide an overview of the object and related attributes. For more information about a certain attribute (datatype, description etc.), hover over the definition of the attribute. Hovering over a calc will provide information about parameters, return values, quality etc.

• SignatureHelp is provided when writing calcs inside CalcPvr.Alg. The signature is shown with the active parameter highlighted together with the documentation of the active parameter. SignatureHelp can be manually activated by pressing Ctrl + Shift + Space.

• Search functionality for calcs are builtin into the completion. To start searching, start typing the search word into the CalcPvr.Alg field and all calcs that has the relevant search word in the documentation is included in the filtered results. Pressing Ctrl + Space starts the completion without a starting phrase and can be used to browse all available calcs and variables inside a CalcPvr.Alg.

• Code action for fixing references to unknown Xvrs are provided for CalcPvr. The code action can be activated by hovering over the relevant diagnostics in the file and pressing the QuickFix button. You can then select the Insert Evr code action. An Evr with the same name as the missing reference will then be inserted within the same DmmyAppl as the CalcPvr. The placement can be adjusted by changing the setting septic.codeActions.insertEvrPosition. Top means that the evr is inserted right below the DmmyAppl object, while bottom means right above the CalcModl object

• Commands can be run by pressing Ctrl+Shift+P and searching for Septic.

  • List OPC Tag: Select the desired config/scg-context from the list of available configs/scg-context. If the desired config is not listed, make sure that it is placed in the workspace folder and open the file. A csv file with the OPC-tags is generated in the root of the workspace.

  • Detect cycles: Select the desired config/scg-context from the list of available configs/scg-context. If the desired config is not listed, make sure that it is placed in the workspace folder and open the file. A text file with all the detected cycles in the config/scg-context sorted by length is generated in the root of the workspace.

  • Compare configs: Select the previous version of the config from the file explorer. Select the current version of the config from the file explorer. The user can select if the default settings for comparing configs or provide their own settings. Settings are provided in yaml-files and the user are promted to either select the default or a yaml file in the current workspace. A text file with the detected changes is generated in the root of the workspace. Tip: Press Ctrl + k Ctrl + 0 to get a dense view of all updated objects. Example settings file:

    ignoredVariables: # List of regexes for variables that should be ignored
    - ^A1.*
    ignoredObjectTypes: # List of object types that should be ignored
    - DisplayGroup
    ignoredAttributes: # List of attributes pr object type that should be ignored
    - objectName: Evr
        attributes:
        - Meas

• Septic Co-Pilot features powered by Large Language Models (LLM):

  • Chat participant @septic. The following commands are available:
    • \calcs which is specialized in generating calculations based on the description from the user. The suggested calculations are quality checked by the Septic diagnostics provider to increase the quality of the output. Co-Pilot reiterate up to 3 times based on the feedback from the diagnostics provider.
  • Code action for generating Alg attribute for a CalcPvr based on the Text1 description is available by selecting the relevant CalcPvr with the cursor and selecting Generate Calc: CalcPvrName in the code action options. The generated calc is filled in the Alg field.The suggested calculation is quality checked by the Septic diagnostics provider to increase the quality of the output. Co-Pilot reiterate up to 3 times based on the feedback from the diagnostics provider.
  • Septic documentation is used as input to the Large Language Models (LLM) powering the Co-Pilot and is selected based on the selected version in the workspace. The context (available variables etc.) is also provided to the chat participant. The current active editor is used to select the right context (i.e. the scg-context or standalone cnfg).

The extension supports Septic projects that uses the Septic Config Generator (SCG). The SCG-config file for the project is loaded and the relevant .cnfg files (required to be in the templates folder) listed in the layout section are loaded into a common context that shares references etc.

Additional recommended extensions for working with Septic config files

• Snippet Creator: For creating your own snippets.
• Color Highlight: Handy if you want to experiment with colors since it can display the color of hex triplets, e.g. "#f0f0f0", inside VSCode.
