NF-U429-012 GS: Strip whitespaces when creating Ada units (2021-07-05) GNAT Studio now automatically strips trailing and ending whitespaces when creating Ada units via the New/Ada package and New/Ada Main contextual menus. NF-U412-038 GS: Visual feedback for empty Outline view (2021-04-15) The Outline view now displays a 'No symbols available' label when there are no symbols available in the current context. This can be the case for empty files or if a given language is not supported by GNAT Studio. NF-U326-032 GS: Error feedback in GPS.Process API (2021-04-15) When using GPS.Process methods (like kill or send) return an exception if the process is dead or not started. NF-U128-046 GS: Hierarchical directories in the Project view (2021-02-23) The "Hierarchical directories" local configuration menu has been added to the Project view. When set, source directories are shown as a tree, corresponding to their real positions on disk. Works together with 'Group by directories'. NF-TB30-020 GS: New menus to reset language servers (2020-12-09) A submenu has been added to the Navigate global menu, allowing resetting of the language servers (that is, the underlying engine for a given language) spawned for the current project.

NF-TA06-032 GS: New 'expand all' action for the Project view (2020-10-20) A new 'expand all' action has been added, allowing expansion of all the nodes of the Project view at once. A local toolbar button has also been added. NF-T924-005 GS: Commenting/uncommenting blocks in project files (2020-09-29) It is now possible to use Comment/Uncomment Lines actions in project files. NF-T923-040 GS: "Pretty Print" in toolbar and contextual menu (2020-10-06) "Pretty print" icon has been added in the toolbar and also into the contextual menu.

NF-T817-009 GS: New "Pending breakpoints" debugger preference (2020-08-27) A new preference has been added to allow pending breakpoints when using the debugger. When enabled, breakpoints that are not recognized when starting the debugger (i.e: breakpoints set on dynamic libraries) won't be rejected: the debugger will try to set them once the executable runs. This preference is enabled by default. NF-T811-009 GS: Phase information in task manager (2020-10-20) Command-line tools can now display phase information in the task manager in addition to progress information. NF-T807-069 GS: Show only errors preference (2020-09-30) Add a new local preference named "Show only errors" in the Locations view. When enabled, it will filter the view to only show high importance messages. NF-T804-011 GS: Support for LSP textDocument/signatureHelp (2020-08-12) GNAT Studio now supports the textDdocument/signatureHelp request. When implemented by the server (for example, clangd), this request is used to provide information on parameters (for example, the function's profile) while writing a function call. It's usually triggered when opening a parenthesis after a function name. NF-T714-013 GS: Improved warnings on illegal package names (2020-08-07) When creating a package via the New/Ada package contextual menu, GNAT Studio now warns the user if the specified name is incorrect (for example, if a keyword is used for the package name). NF-T701-032 GS: Set breakpoints with the Assembly view (2020-07-29) The new tool button in the Assembly local toolbar allows setting and deleting breakpoints at given addresses. NF-T615-034 GS: Display Ada version switches as radio buttons (2020-06-26) Ada version switches (e.g.: -gnat05) are now displayed as radio buttons in the Project Properties, to avoid being able to select multiple versions at the same time.

By default, all the scenario variables are explicitly expanded. When the preference is deactivated, only variables with a value different from their default will be expanded. NF-T609-006 WB: Improve RUNTIME handling in Workbench projects (2020-06-15) The RUNTIME value defined by scenario variables and GNAT project files is now used by the generated makefile for WindRiver Workbench projects.

NF-T520-041 GS: Fuzzy completion filtering (2020-12-09) A new 'Completion filter mode' preference has been added to control the way completion items are filtered once the completion window is opened. When set to 'Fuzzy', filtering is done in a fuzzy way, allowing matching items from a subset of the letters. NF-T430-047 GS: More extensions recognized as C++ (2020-05-07) GNAT Studio now recognizes as C++ files with the extensions .cc, .cp, .cxx, .c++, .hpp, .hxx, .inl (in addition to .hh and .cpp). This allows easier setup for projects that import libraries which use these extensions. NF-T429-008 GNATDASHBOARD: Support for SonarQube 7.9 LTS (2020-05-15) The Sonar Ada plugin was updated in order to support SonarQube 7.9 LTS. The older versions of SonarQube are no longer supported. NF-T421-014 GS: Improvements regarding GNATemulator integration (2020-05-01) The integration between GNAT Studio and GNATemulator has been improved: the same GNATemulator console is now reused across debugging sessions, instead of spawning a new one each time the user starts a new debug session. A clean button has also been added to the console. An issue regarding the debuggee's output has also been fixed: the output is now properly displayed even when the GDB-mi mode is enabled. NF-T330-042 GS: Take env changes into account for navigation (2020-03-31) The capability to reload the language servers after changes in environment has been implemented. NF-T327-033 GS: Support for LSP completion snippets (2020-05-04) Support for LSP completion snippets has been introduced in GNAT Studio. Completion snippets can be sent by the underlying language server to speed up development (that is, snippets for subprogram calls, with placeholders for all the needed parameters). NF-T311-021 GS: Add contextual menus for copy_file_name plugin (2020-03-19) Contextual menus have been added for the "copy_file_name" and "copy_base_name" actions defined in the copy_file_name.py plugin.

NF-T305-033 GS: New 'Close all other tabs' contextual menu (2020-12-10) The old 'Close all editors' menu has been renamed to 'Close all editor tabs', allowing users to close all the other tabs of a given notebook in GNAT Studio, and not only the other editors. NF-T304-055 GS: Untyped variables returned by scenario_variables (2020-11-26) The scenario_variables Python API request now also returns untyped variables. NF-T210-040 GS: Dialogs to report messages in initialization (2020-02-12) Dialogs are now generated to display more information about some errors which could occur during the initialization of GNAT Studio, such as an invalid or unreadable home directory. NF-T210-012 GS: Allow running from the debugger toolbar (2020-02-10) The "Start/Continue" button in the debugger toolbar now offers the option to stop at the beginning of the main, just like the Debug->Run... menu.

NF-SB05-022 GS: Navigation between messages of same importance (2019-12-09) Add "previous/next tag (same weight)" actions which allow in the Locations view to move between messages of same importance. (I.E. if an error is selected the action will find the previous/next error). NF-SA30-034 GS: Disable automatic reload of unsaved files (2020-01-09) A dialog will always be shown when detecting conflicts between unsaved editors and the actual files on the disk.

NF-SA14-007 GS: Navigation to parent/child implementations (2019-12-17) When navigating to the definition or implementation of a subprogram via ctrl-click or via the contextual menu, if this is requested on a primitive of a tagged type, GNAT Studio will propose the option to navigate to the declarations that override or that are overridden by the current one. NF-SA10-035 GS: New actions to move block up/down one line (2019-12-05) New actions "Move block up" and "Move block down" have been added to move the current line or selected block up or down one line.
