This extension was originally named 'AL Code Outline' because it started as AL code outline panel from which it was possible to run different code generators on AL syntax nodes. Each new version has been adding new features, some of them were no longer related to the AL code outline panel. Current version of the extension is a collection of different al development tools and al outline panel is just one of them, so it seems that the name should be updated to reflect functionality changes.
"AZ AL Dev Tools/AL Code Outline" extension is a collection of these tools designed to help with AL extension development:
- AL objects wizards
- Symbols browser
- AL symbols outline panel
- Symbols tree view
- AL code generators
- Code actions
- Code transformation commands
- Action images browser
- Custom editors
- Documentation comments support
- Code analyzers rules viewer
- Document syntax visualizer
AL objects wizards
Extensions add new "New AL File Wizard" item to EXPLORER context menu. It allows to run one of these wizards to create new AL object file:
- Table Wizard
- Table Extension Wizard
- Page Wizard
- Codeunit Wizard
- Interface Wizard
- XmlPort Wizard
- Report Wizard
- Query Wizard
- Enum Wizard
- Enum Extension Wizard
Symbols browser shows list of AL objects, allows to select one of them and then display details of that symbol. It is also possible to select multiple objects (by clicking on nodes with Ctrl key or using Ctrl+A) and then use context menu to run one of code generators on them. Browser can display symbols in 2 modes - list and tree view. In tree view screen is split into two parts showing objects tree on the left side and selected symbol on the right. In list view browser shows flat list of symbols and uses "AL Outline" panel to show details of selected object.
Both views support keyboard navigation with arrow keys and allow to filter data by using filter fields at the top of the screen.
Symbols browser can display symbols from:
- *.app symbols files - extension registers default custom read only editor for these files so symbols browser can be opened by just clicking on the file in the EXPLORER panel. If it does not work, it means that other editor has been selected as default. In that case symbols browser can still be open by right clicking on the file, selecting "Open With..." from the context menu and choosing "AL App Viewer" editor.
- current project symbols with all dependencies defined in app.json by running "AZ AL Dev Tools: Show All Project Symbols" from the "Command Palette"
- current project symbols without dependencies by running "AZ AL Dev Tools: Show Project Symbols without Dependencies" from the "Command Palette"
AL symbols outline panel
'AL Outline' panel displays code outline of the currently active editor. Basic functionality allows user to click on one of the symbols tree nodes to move cursor to that symbol in the code editor. It looks like standard VS Code Outline view, but supports syntax node types specific to AL, display custom icons and allows to invoke some commands on them using context menu. Currently symbol context menu allows user to run pages, reports and tables in the web client and run code generators to create new card and list pages, reports, xmlports and queries with all fields from selected table symbols. For tables and pages it is also possible to create page or table extension.
Symbols tree view
This view shows symbols tree looking similar to content of "AL symbols outline panel", but uses WebView to display it and can be opened on one of the editor tabs. If there is an editor in which user changes definition of the object displayed in the tree view, tree content will be updated, but switching active editor to other file does not change the tree. It can be used to display table symbols when user edits page object or page symbols when developers edits page extension. View can be opened from:
- AL Symbols Browser by using object list context menu and selecting "Open symbol in new tab" option
- "Show Document Symbols Tree" command from "Command Palette" when there is an acive text editor with AL file
- Editor context menu by selecting "Show Definition in the Symbols Tree" menu item
AL code generators
Extension contains code generators that can create new card and list pages, reports, xmlports and queries with all fields from selected table symbols. It can also create empty page or table extension from page or table symbols. Generators can be invoked using context menu on symbols in "AL Outline" view and in "Symbols Browser".
When new objects are created, generators use "CRS AL Language Extension" templates functionality to suggest file names.
Extension adds VS Code editor code actions to some of al elements to help developers modify or insert code quickly. At this these types of actions available:
- Sorting actions that can sort
Sort table fields available when cursor is at the first line of table, table extension, fields keyword or table/table extension field. It will sort all fields by the field number.
Sort procedures available when cursor is at the first line of a procedure. This action will sort procedures of the same type (i.e. local) in a natural order
Sort data item columns available when cursor is at report data item, column or first line of the object declaration. This action will sort all columns inside data item in a natural order. If it is invoked from the first line of the object, it will sort columns inside all data items.
Sort properties available from the first line of any object declaration. It will sort properties of every element declared inside the object.
Sort variables available from the first line of any object declaration or from "var" keyword of local or global variables section
- Code generation actions
Create interface action available on the first line of codeunit declaration, it creates a new interface with all public functions from the codeunit
Add multiple fields when cursor is at these elements in the editor:
- "group" and "repeater" on pages
- "group", "repeater", "addfirst", "addlast", "addafter" and "addbefore" on page extensions
- "dataitem" on reports
- "dataitem" on queries
There are also
Add multiple field elements and
Add multiple field attributes actions available at "tableelement", "fieldelement" and "fieldattribute" elements on xml ports.
Fields can be added is selection or alphabetic order, it can be controlled using "alOutline.fieldsSelectionOrder" setting. Default value is "selection order".
Sort procedures, variables, properties and report columns actions can be also run automatically on document save. To turn this functionality on "source.fixAll.al" property of "editor.codeActionsOnSave" must be set to true and "alOutline.codeActionsOnSave" setting should contain list of sorting actions that you want to run. That's how settings should look like to run all these sort actions on save:
"SortProcedures", "SortProperties", "SortReportColumns", "SortVariables"
There are also some additional code actions available for warnings and errors reported by CodeCop code analyzer:
- add parentheses for diagnostics AA0008,
- remove variable for diagnostics AA0137,
- add CopyStr for diagnostics AA0139
Code transformation commands
Extension adds a few commands that allow to automatically modify al code in the current editor or in all project files. Currently these commands are available:
Add Application Areas to the Active Editor: adds missing application areas to all page controls in the current editor
Add Application Areas to the Active Project: adds missing application areas to all page controls in the current project
Add ToolTips to the Active Editor: adds missing tooltips to all page fields and actions in the current editor
Add ToolTips to the Active Project: adds missing tooltips to all page fields and actions in the current project
Add Table Field Captions to the Active Editor: adds missing captions to all table fields in the current editor
Add Table Field Captions to the Active Project: adds missing captions to all table fields in the current project
Add Page Controls Captions to the Active Editor: adds missing captions to page controls in the current editor
Add Page Controls Captions to the Active Project: adds missing captions to page controls in the current project
Add Object Captions to the Active Editor: adds missing captions to all table, page, report, xmlport and query objects in the current editor
Add Object Captions to the Active Project: adds missing captions to all table, page, report, xmlport and query objects in the current project
Remove 'with' usage from the Active Editor: removes all implicit and explicit 'with' usage from the current editor
Remove 'with' usage from the Active Project: removes all implicit and explicit 'with' usage from the current project
Default application area and templates for field and action tooltips can be specified using these VS Code settings:
Action images browser
Extension adds new "AZ AL Dev Tools: Show Action Images" command to the "Command Palette" to load all available action images from active Microsoft AL Language extension and show them in a single web view panel. Action images browser supports filtering, keyboard navigation and adds context menu to each image on the list. Context menu contains these 3 actions:
- Copy name - copies image name to the clipboard
- Copy as action - generates page action element and copies it to the clipboard
- Copy as promoted action - generates promoted page action element and copies it to the clipboard
Extension adds new custom editors for app.json, rulesets (*.ruleset.json) and AppSourceCop.json files. These editors are defined as "secondary" which means that developers have to right click on the file in the EXPLORER and choose "Open With..." option. It will display list of available editors for selected file. It is also possible to change default editor on this list.
When developer types "///" in a line above a symbol declaration (i.e. variable, procedure, field), extension can add "Xml Documentation Comments" to the list of available completion items. When it is selected, xml documentation snippet will be inserted into the code editor. If symbol below cursor is a procedure declaration, inserted snippet will contail all procedure parameters. This functionality can be turned off and on by changing "alOutline.docCommentsType" setting to "none" or "xml".
Code analyzers rules viewer
Code analyzers rules viewer can be opened by running "AZ AL Dev Tools: Show Code Analyzers Rules" command. It allows to select one of available code analyzers from a dropdown list and then displays all rules implemented by that analyzer in a table view. It is then possible to select some or all of the rules and create new ruleset file or copy them as ruleset rules or a table to the clipboard using context menu.
Document syntax visualizer
Document syntax visualizer shows syntax tree created by the AL compiler for the current document. It can be opened by running "AZ AL Dev Tools: Open Document Syntax Visualizer" command. The main purpose of this functionality is to help developers create their own al code analyzers. More information how to create analyzer can be found on my blog here: https://anzwdev.wordpress.com/2019/11/09/custom-al-code-analyzers/

This extension has originally been inspired by "Code Outline" extension created by Patryk Zawadzki and "Tree Data Provider" example from "VS Code Extension Examples". I've decided to create it because I wanted something that could understand AL object structure and to be able to add some AL specific commands to tree nodes in the future.
This extension contributes the following settings:
alOutline.addDataItemToReportColumnName: include data set name in report columns names
alOutline.docCommentsType: enable documention comments, available values: none, xml
alOutline.autorefresh: refresh code outline tree automatically
alOutline.autoGenerateFiles: automatically generate files for newly created objects
alOutline.autoGenerateFileDirectory: the default directory to create files in, relative to the root directory (e.g., "Source<ObjectType>")
alOutline.autoShowFiles: automatically show any newly created files in the editor
alOutline.defaultAppArea: default application area for page code generator
alOutline.defaultListUsageCategory: default usage category for list pages
alOutline.promptForObjectId: when generating a new object, ask the user to input the object ID.
alOutline.promptForObjectName: when generating a new object, ask the user to input the object name
alOutline.promptForFilePath: when generating a new file, ask the user to specify a path relative to the root of the project-folder
alOutline.stripNonAlphanumericCharactersFromObjectNames: always strip non-alphanumeric characters from generated object names
alOutline.webClientPort: web client port number, use 0 for default http/https ports
alOutline.openDefinitionInNewTab: set to true to always open documents in a new tab from "Go to definition" command in "AL Object Browser"
fieldsSelectionOrder: specifies how "Add multiple fields" functionality adds fields, available options are: "alphabetic" and "selection order"
alOutline.codeActionsOnSave: list of code actions that should be run on document save, available options are: SortReportColumns, SortProperties, SortProcedures, SortVariables
alOutline.pageActionToolTip: default tooltip template for page actions. Use %1 as placeholder for action caption or name
alOutline.pageFieldToolTip: default tooltip template for page fields. Use %1 as placeholder for field caption or name
alOutline.addToolTipsToPageFields: set to true to add tooltips to page fields when 'Add multiple fields' action is used
- It takes some time to parse all *.al files when new project is opened so code outline will stay empty during that time.
- Extension uses CRS-AL-LANGUAGE-EXTENSION for generating file names for new objects. As a result you will see plenty of new snippets added by the CRS extension. If you don't want to see them, go to Visual Studio settings and disable them in CRS-AL-LANGUAGE-EXTENSION section.
