Goclipse Versions Save

• Updated minimum CDT to version 9.0 (CDT from Eclipse Neon).
• Removed effectively useless "Start gocode server automatically" preference.
• The GOROOT environment variable is no longer set when invoking Go tools (such as go, gocode, godef, etc.). (#214)
  • This causes problems with non-archive Go installations (such as those installed into /usr/bin), and the reason why it was set in the first place is not known - probably legacy code. Google also seems to indicate GOROOT should not be set explicitly.
• Fixed: NPE when invoking Content Assist inside a comment, string or character.
• Fixed 0.16.0 regression: editor open definition hyperlink (Ctrl+click) not working. (#208)
• Fixed 0.16.0 regression: Assertion exception when opening Go files in the compare editor. (#211)

• Added documentation hover (F2 or mouse-over the reference). Also documentation added to code completion popup.
• Added insertion of function arguments for function code completion proposals.
• Enabled gocode's propose-builtins option, which isn't enabled by default.
• Reworked the icon and label of code completion proposals and fixed some related issues. Now the icons are consistent with the Outline icons.
• Removed preference "Show error dialog if gocode failures occur" as it's no longer necessary.
  • Content Assist will now distinguish between setup errors (errors that the user can fix, which are related to configuration and not the source code) and other tool errors. For setup/critical errors, a dialog will always be shown. For the other errors, if Content Assist was invoked manually, a dialog will also be shown, but if it was activated automatically the error will only be displayed in the editor status line.
• Improved gofmt error message.
• Added: show Project Explorer error element if project is not contained in GOPATH.

• Fixed: Eclipse variables not being substituted in environment-variable values of Build Targets and launch configurations.
• Fixed: Project Explorer GOPATH elements not updated if project GOPATH settings changed.
• Fixed: Progress dialog never showing up when "Ok" pressed in LANG_NAME project properties page.
• Fixed: Erratic text cursor bug when typing in GOPATH field and gofmt field.

• Added support for lint build target, using gometalinter. (#163)
• Added customization of the build command for Build Targets: It's now possible to specify a command other than the default one (the go tool).
  • Note however that Goclipse still expects the output of the command (the error messages) to be in the same format as the go tool (or gometalinter).
• Added support for invoking a specific Build Target when a GoClipse editor is saved. This is called "auto-check", and is intended for build commands that only check for compilation errors, but don't produce artifacts. This has the potential to be faster than a regular build.
  • Added Building section to documentation.
  • The goal for the future is to enable invoking this command on-the-fly (as the user types), although for this to be useful in practice it will likely require the compiler to support incremental compilation (or be super fast otherwise).
• Added support for modifying the environment variables of a Build Target's build command. (#191)
• The Go oracle tool is now the guru tool. GoClipse has been updated to reflect this.
• Improved the default names for automatically created launch configuration.
• Improved error display for Outline operation failures.

• Fixed "IllegalStateException: The service has been unregistered" on Mars.2 when Eclipse is closed.
• Fixed: Don't call editor save actions (such as gofmt) when Open Definition is requested.

• Added godef integration. godef is used as an alternative to oracle for the Open Definition operation.
  • I wasn't able to use it extensively, but it seems to be more powerful than oracle (it can recover from some compiler errors for example), and faster. Indeed, most other Go IDEs/editors are using godef, so this bring Goclipse in line with that.
• Added "Format automatically on editor save." preference.
• gofmt preferences moved to "Go/Tools" preference page.
• Minor improvement to editor caret position preservation when invoking gofmt.
• Added signing to releases.
• Removed GOOS and GOARCH from preferences, they no longer have an apparent use.
• Removed godoc preference.
• Fixed: Incorrect icon for errors and warnings in preference page status.
• Fixed: Can't save preference pages with empty fields.
• Fixed: Problem markers for the #build-tests target would not be created for Eclipse projects inside a GOPATH entry.

• Added on-the-fly parser errors in the editor (uses Go oracle).
• Added some new Snippets: for, foreach, switch, main, apl and a few others.
• Added improved download functionality in gocode/oracle preference page.
• Pressing F2 in the editor now shows information popup for problem under cursor (same as the mouse-over hover).
• Project builder is no longer invoked when workspace "Build Automatically" setting is enabled and a file is saved. (this was considered a misfeature anyways)
• Dirty editors are now automatically saved if a build is invoked directly from a Build Target in the Project Explorer. (if the workspace "Save automatically before build" option is enabled).
• Improved Auto-Indent when Enter pressed before a closing brace.
• Added preference to control whether project location is implicitly added to GOPATH or not.
• Added gocode preference to enable/disable showing the error dialog if failures occur during Content Assist.
• Minimum and recommended CDT version is now 8.8.

• Partially fixed outline not showing some method declarations. Now it works when editor is saved, but not if the editor is dirty. (#177)
• Fixed NPE when invoking Open Definition in a file that is available in the Eclipse workspace under more than one path/location. (#167)
• Fixed bug with Content Assist snippets using the ${word_selection} variable.
• Fixed workspace resource locking when a build is invoked directly from a Build Target in the Project Explorer.
• Fixed regression: Console view always activates when a build is invoked. (#158)
• When debugging, fixed toggling breakpoints on and off for files that are outside the workspace.
• When debugging, fixed opening source files that are are outside the workspace.
• Fixed line breakpoint icon.
• Fixed: in New Go File Wizard, "Browse" button not working.
• Fixed: "Restore Defaults" in "Go Compiler" settings page sometimes causes GOPATH field to be enabled when it shouldn't.
• Fixed: project Build Targets settings pages shows wrong default for Program Path field.

• Added support for Eclipse dark theme (#131). Namely:
  • Syntax/source coloring now have different settings for dark theme.
  • Fixed Tools Console colors, as well as content assist pop-up colors.
• Added number literals syntax highlighting. (#138)
• Syntax highlighting now works on the source compare editor/viewer.
• Added per-project compiler installation preferences. (#152)
• Newly created launch configurations now have the debug option "Stop on startup at:" set to false by default. This way debugging won't stop on the C main, which is essentially useless outside of C/C++.

• Fixed: Quick outline breaks when file begins with /* */. (#160)
• Fixed: Preferences: custom setting for gofmt command is not saved. (#166)
• Fixed: AssertionFailureException pressing Enter after source with more closing braces than opening ones.
• Fixed: Unindent (Shift-Tab) broken, does nothing after empty lines in selection.
• Fixed: Outline broken, due to error "CommonException: Invalid line, out of bounds". (#156)

• Go build now displays GOOS and GOARCH environment variables in build/tools console, if a non-default value is set.
• Added UserGuide note about using Homebrew GDB in OS X.
• Fixed: when invoking Go toolchain programs, add tool directory to beginning of PATH, not end.
• Fixed: In Linux, the "Build Target" group UI widget height is broken, too short. (#150)
• Fixed: if build tool reports many error messages, the Eclipse project build will take too long to finish.
• Fixed: "Run As"/"Debug As" launch shortcut incorrectly matching pre-existing launch configurations.
• Fixed: project not being refreshed when Build Target build invoked directly from Project Explorer.
• Fixed: "null" text inserted when cancel pressed in "Variables..." and other dialogs.
• Fixed: Launch Configuration Main tab fields incorrectly modified when a new Build Target is selected (if Build Target is not using defaults)

• Added: support for Build Targets:
  • Build Targets are displayed in the Project Explorer. Here you can also configure which targets are enabled for a workspace build.
  • Predefined Build Targets for Go are: ./... #build, ./... #build-tests, ./... #[run-tests]. See the updated Build section in the UserGuide for more information.
  • Project Build Configuration property page updated to support configuring Build Targets.
  • Note that a ./... Build Target is not launchable. To run a Go launch, you need to specify a specific Go package.
• Added: Explicit GOPATH preference option to use the same value as the GOPATH environment variable.
• No longer required to set an explicit value for the GOOS and GOARCH preference for running tools such as Go Oracle. You can just leave those fields at the default setting.
• No longer showing error dialog when gocode fails. Now, only the editor status line is updated.
• Removed go fix menu operation.
• Updated Configuration section in the User Guide.
• Fixed: Occasional AssertionFailure when creating new projects in nested locations (the project would not show up in Explorer).
• Fixed: Arguments field in launch configuration is not multi-line.

▶ Recommended/tested CDT version is now 8.7

• Fixed: Debugging not working on Eclipse 4.5 Mars (CDT 8.7), for certain platform/GDB combinations.
• Fixed: NPE launching a Go launch with a Go package that doesn't exists.
• Doc: added note about Cygwin GDB not being recommended for debugging.

• Fixed #135: Cannot set breakpoints in editor.
• Fixed: PATH of external tools bungled if original PATH not set (Windows).
