GoSublime Changelog

18.11.28

This release introduces the HUD and comes with many improvements to snippets and a tweaked version of the Mariana color schemed named Ariana.

  • The HUD is an output panel that’s automatically populated with info traditionally found in the status bar and various pop-ups/tool-tips.
    Currently, the following info will be displayed there:
    • The Issues status, including the error messages for the current line.
    • The GocodeCalltips status, including positional highlighting of params and return statement.
      It’s bound to the keys ctrl+.,ctrl+0.
      You can manually bind it to another key. e.g. via Preferences > Key Bindings:
      {
        "keys": ["ctrl+0"],
        "command": "margo_show_hud",
      },
    
  • Several new snippets have been added and old ones improved.
    • AppendSnippet: name = | suggests:
      • name = append(name, ...)
      • slice = append(slice[:len(slice):len(slice)], ...)
    • DeferSnippet:
      • defer func() {}()
      • defer f()
    • ReturnSnippet:
      • return
    • MutexSnippet: mu.| suggests:
      • mu.Lock(); defer mu.Unlock(); |
      • mu.Lock(); |; mu.Unlock()
    • PackageNameSnippet:
      • package main; func main() { | }
    • DocSnippet: suggest function names, field names, etc. inside the corresponding documentation comment
  • Fix the golang.Gocode{} reducer changing View.Pos
  • The (Add)UnimportedPackages feature no longer adds circular imports
  • Show the tasks animation after 500ms instead of 1s to (hopefully) make things feel more responsive
  • GOROOT and GOPATH are scanned in parallel at startup
  • All packages in GOROOT and GOPATH are available for the unimported packages feature, not just those in GOROOT and the package cache.
  • Add better named alias pkg-list for unimported-packages and show the directory where the package is
  • API BREAKAGE:
    Most users should not be affected, but there were some API changes/breakages.
    • removed CursorScope.Any and CursorScope.All
    • make CursorCtx.Pos the int offset instead of token.Pos
    • CursorNode and ParseCursorNode were removed
    • CursorCtx.Ctx is no longer embedded

18.11.06

  • Fix UnimportedPackages support for stdlib packages in go1.10 and earlier versions.

18.11.04

  • API BREAKAGE: Rename mg.Reducer.Reducer* to mg.Reducer.R*.
    Most users should be unaffected.
    If you’ve called any of these methods directly,
    you will need to rename the following method calls:
    • ReducerLabel -> RLabel
    • ReducerInit -> RInit
    • ReducerConfig -> RConfig
    • ReducerCond -> RCond
    • ReducerMount -> RMount
    • Reducerduce -> Rduce
    • ReducerUnmount -> RUnmount
  • API BREAKAGE: mg.RunCmdData has been un-exported
  • The following fields in the &golang.GoCode{} and &golang.GocodeCalltips{} reducers are now ignored.
    • Source: this is now the default
    • ProposeBuiltins: this is now the default
    • ProposeTests: use &golang.MarGocodeCtl{}
    • Autobuild: we now use the source code so there are no plans to implement this
    • UnimportedPackages: this is now the default
      See &golang.MarGocodeCtl{} (below).
  • Add support for ‘unimported’ packages.
    • auto-completing json. will now try to import encoding/json
    • known bugs: when adding the import, the view will scroll
    • known limitation: we don’t scan GOPATH and we don’t support the vendor directory
      Use NoUnimportedPackages (below) to disable this.
  • Add support for preloading imported packages when a view is activated.
    • This aims to keep the cache warm to speed up auto-completion.
      Use NoPreloading (below) to disable this.
  • Add support for adding unimported packages to the file.
    • Use AddUnimportedPackages (below) to enabled this
  • All the above can be configured using the &golang.MarGocodeCtl{} reducer
    &golang.MarGocodeCtl{
      // whether or not to include Test*, Benchmark* and Example* functions in the auto-completion list
      // gs: this replaces the `autocomplete_tests` setting
      ProposeTests: false,
      // Don't try to automatically import packages when auto-compeltion fails
      // e.g. when `json.` is typed, if auto-complete fails
      // "encoding/json" is imported and auto-complete attempted on that package instead
      // See AddUnimportedPackages
      NoUnimportedPackages: false,
      // If a package was imported internally for use in auto-completion,
      // insert it in the source code
      // See NoUnimportedPackages
      // e.g. after `json.` is typed, `import "encoding/json"` added to the code
      AddUnimportedPackages: false,
      // Don't preload packages to speed up auto-completion, etc.
      NoPreloading: false,
      // Don't suggest builtin types and functions
      // gs: this replaces the `autocomplete_builtins` setting
      NoBuiltins: false,
    },
    
  • Add new lang conststants for mg.JSX, mg.TS, mg.TSX and rename R to Rlang
  • Don’t treat an empty non-nil slice as matching in LangIs() and ActionIs()
  • Fix an infinite loop when auto-completing inside packages with cyclic dependencies

18.10.06

  • restore support for running individual test functions by pressing ctrl+.,ctrl+g or ctrl+shift + left/right-click on the function declaration’s name
  • add support for having multiple builtins with the same name
  • API breakage:
    mg.ExecRunFunc() was replaced with the pattern CmdCtx.WithCmd().Run()
    the former bypasses builtins so running go install has no linting support

18.09.30

  • Improve autocompletion scope detection
    • snippets should now the shown when there is a comment above the package statement
    • completion should no longer be shown when there is no package statement
  • misc tweaks to the method snippets
    • for pointer method receivers, only the * is selected for the initial method definition
    • when there are syntax errors in the file, methods should no longer be suggested for the invalid type _

18.09.25

  • Switch golang.Gocode and golang.GocodeCalltips to new mode SrcImporterWithFallback by default
    This should improve the experience a lot:
    • in the old Source: true mode, CGO packages often failed
    • in the old Source: false mode, you had to make sure the package was installed
      and up-to-date
    • in this new mode, we try the more reliable source mode and fallback
      to the binary mode if it fails
      As a result, the Source: bool fields are now ignored.
      To restore the old behaviour, use the golang.MarGocodeCtl reducer:
    &golang.MarGocodeCtl{
      ImporterMode: golang.SrcImporterOnly,
      // or
      ImporterMode: golang.BinImporterOnly,
    }
    
  • replace margocodectl cache-list-by-key and cache-list-by-dur with cache-list
    see margocodectl cache-list --help
  • Improve FmtCmd’s error message
    When goimports fails due to a syntax error, the parse error should now be shown as well
    and not just the meaningless exit 2 error message

18.09.18

  • fix a case where margo exits due to IPC shutdown
    you will need to restart Sublime Text
  • return all possible completions in gocode to allow the editor to do filtering.
    this restores the old behaviour where typing abc.X proposes abc.XYX123

18.09.14

  • This release adds a new experimental update notifier.
    MOTD keeps you updated about new versions and important announcements
    It adds a new command motd.sync available via the UserCmd palette as Sync MOTD
    Interval can be set in order to enable automatic update fetching.
    When new updates are found, it displays the message in the status bar
    e.g. ★ margo.sh/cl/18.09.14 ★ a url where you see the upcoming changes before updating
    It sends the following data to the url https://api.margo.sh/motd.json:
    • current editor plugin name e.g. ?client=gosublime
      this tells us which editor plugin’s changelog to check
    • current editor plugin version e.g. ?tag=r18.09.14-1
      this allows us to determine if there any updates
    • whether or not this is the first request of the day e.g. ?firstHit=1
      this allows us to get an estimated count of active users without storing
      any personally identifiable data
      No other data is sent. For more info contact privacy at kuroku.io
      To enabled it, add the following reducer:
    &mg.MOTD{
      // Interval, if set, specifies how often to automatically fetch messages from Endpoint
      // Interval: 3600e9, // automatically fetch updates every hour
    },
    
    You will need to restart Sublime Text.
    Unless you uncomment/set Interval, you will need to manually check for updates
    using the Sync MOTD command from the usercmd palette
    ctrl+.,ctrl+c / super+.,super+c
  • The GoSublime: Go syntax was switched to a new syntax based on the Go syntax shipped in Sublime Text
    • if you find any breakages, please file an issue at margo.sh/gs/i
    • if you prefer the colouring of the previous version, you can switch back to the old syntax
      via Menu > View > Syntax > Open all with current extension as... > GoSublime > GoSublime: Go (Deprecated)
      please not that this version is buggy and will not receive any fixes
  • golang.Gocode, golang.GocodeCalltips:
    • reduce memory use with Source: true
    • support syscall/js
  • golang.Guru gained support for syscall/js
    guru is now called with -tags "js wasm" if syscall/js is imported in the package

18.08.31

  • Switch the ctrl+.,ctrl+t / cmd+.,cmd+t keybinding to the new &golang.TestCmds{} reducer:
    &golang.TestCmds{
      // additional args to add to the command when running tests and examples
      TestArgs: []string{},
      // additional args to add to the command when running benchmarks
      BenchArgs: []string{"-benchmem"},
    },
    

18.08.29

  • implement more aggressive gocode caching.
    behind the scenes, imported/type-checked packages are cached until the respective package is edited.
    • it should now be ok to use Source: true option without slowdowns.
    • as a bonus, go modules should now have completion with Source: true
    • please note that Source: true uses a lot more memory (see below for details about cache pruning)
    • if both &golang.Gocode{Source: true} and &golang.GocodeCalltips{Source: true}
      use Source: true, they will share the cache (less memory use)
  • add new reducer &golang.MarGocodeCtl{}
    this allows manual cache management using the new margocodectl command
    • to clear the cache use the command margocodectl cache-prune
      run margocodectl for info about how to use the command
    • automated cache pruning will be implemented in the future

18.08.22

  • merge all shell env vars named ^(MARGO|GO|CGO)\w+ into the GoSublime environment
    this ensures new env vars like GOPROXY and GO111MODULE work correctly
  • try to prevent GO111MODULE leaking into the agent build process
  • add support for UserCmd prompts
    this enables the creation of UserCmds like the following, without dedicated support from margo:
    mg.UserCmd{
      Title:   "GoRename",
      Name:    "gorename",
      Args:    []string{"-offset={{.View.Filename}}:#{{.View.Pos}}", "-to={{index .Prompts 0}}"},
      Prompts: []string{"New Name"},
    }
    
  • fix #853 a build failure when using snap packaged go1.10
  • fix caching of packages in GOPATH when doing gocode completion
    this might slow completion, but there should no longer be any stale non-GOROOT package completions
  • add new Source option to use source code for gocode completions
    this will most likely be very slow
    &golang.Gocode{ Source: true }
    &golang.GocodeCalltips{ Source: true }
    

18.08.15

  • fix missing go command integration by default
  • you may need to add the reducer &golang.GoCmd{}
  • this adds new commands (callable through 9o):
    • go: Wrapper around the go command, adding linter support
    • go.play: Automatically build and run go commands or run go test for packages
      with support for linting and unsaved files
    • go.replay: Wrapper around go.play limited to a single instance
      by default this command is bound to ctrl+.,ctrl+r or cmd+.,cmd+r
      UserCmds (ctrl+.,ctrl+c / cmd+.,cmd+c) are also added for Go Play and Go RePlay
