Changelog

v4.7.0

Enhancements

• #523 - Use the CommonProgramParametersPanel to get the working directory and environment variables the same way the JUnit form does. Replace the custom “Command” input with the “Program arguments” input built into the CommonProgramParametersPanel. CommonProgramParametersPanel expects to store the “Program Arguments” in a “ProgramParameters” field, so old run configurations will lose their “Command” option value and it will be migrated to the new “ProgramParameters”. - @KronicDeth
• #482 - @JakeBecker, @KronicDeth
  • Create / Run Mix ExUnit Run Configurations
    • Run Configuration from Directory
    • Run Configuration from File
    • Run Configuration from LIne
  • Run Configurations support Common Program Parameters
    • Program Arguments
    • Working directory
    • Environment variables
• #531 - @KronicDeth
  • enclosingMacroCall returns enclosing macro call when parent is ElixirDoBlock, so that end element goes to the macro call.
  • Navigate > Test will go to the Module that has the same canonical name as the current defimpl, defmodule, defprotocol , or quote with a Test suffix added
  • Navigate > Test Subject will go to the defimpl, defmodule, defprotocol, or quote that has the same canonical name as the current Module with the Test suffix removed.
• #533 - Regression test for #500 - @KronicDeth
• #545 - Regression test for #517 - @KronicDeth
• #548 - Regression test for #521 - @KronicDeth
• #549 - @KronicDeth
  • Regression test for #525
  • If : is used instead of :: for a type specification, mark it as an error with a Quick Fix to convert : to ::.
  • Highlight = operands the same as :: operands in type specifications.
  • If = is used instead of :: in a type specification, mark it as an error with a Quick Fix to convert = to ::.

Bug Fixes

• #523 - Fix typo: myRunInModuleChekcBox => myRunInModuleCheckBox - @KronicDeth
• #532 - Don’t log error when name length exceeds presentable text length because it appears to be common for normal users and not a development environment artifact. - @KronicDeth
• #533 - Check parent of ElixirMultipleAliases for isVariable because ElixirMultipleAliases can be hit in isVariable when MyAlias. is added on a line above a pre-existing tuple, such as when typing a new qualified call. - @KronicDeth
• #534 - Add space between variable and match in lookup element presentation - @KronicDeth
• #535 - Check VirtualFile is not null before creating attachment because PsiFile can lack a VirtualFile if the PsiFile only exists in memory. - @KronicDeth
• #537 - Convert CallDefinitionClause(Call) to CallDefinitionClause.fromCall(Call), so that null can be returned when CallDefinitionClause.enclosingModular(Call) returns null. - @KronicDeth
• #539 - @KronicDeth
  • Use functionName instead of getName when multiresolving unqualified functions because getName will return the Alias when called on defmodule.
  • maybeQualifiedCallToModular returned null BOTH (1) if the call was unqualified OR (2) if the call was qualified, but its modular could not be resolved, so qualified calls to .beam-only modules, like File.read! returned null because File could not be resolved to a modular. Remove maybeqQualifiedToModular and call qualifiedToModular when myElement is qualified. If the modular is null, then return an empty ResolveResult[] instead of looking for unqualified matches.
  • Pass maxScope to Module reference. maxScope is generally the containing file for the element, but when using Module to resolve imports, it is the import call’s parent element, so that the resolve doesn’t ricochet between the defmodule and its child, the import call until StackOverflowError.
• #545 - A variable cannot be declared in update arguments, so return LocalSearchScope.EMPTY, the same as interpolation. - @KronicDeth
• #548 - ElixirSystemUtil.getProcessOutput already allowed for an empty, invalid ProcessOutput when the workDir wasn’t a directory, so allow it to also be null and return the empty ProcessOutput. - @KronicDeth
• #549 - @KronicDeth
  • If a single keyword pair is used for a type spec, treat : as a type for ::
  • Limit variable use scope for variables “declared” in module attributes to the module attribute because the variable can’t be declared there and it is really a variable usage without declaration.

README Changes

Inspections

Keyword pair colon (:) used in type spec instead of type operator (::)

Type specifications separate the name from the definition using ::.

@type name: definition

Replace the : with ::

@type name :: definition

Match operator (=) used in type spec instead of type operator (::)

Type specifications separate the name from the definition using ::.

@type name = definition

Replace the = with ::

@type name :: definition

Quick Fixes

Convert : to :: in type specs

If a type specification uses a single : instead of ::, then hit Alt+Enter on the : to change it to :: and fix the type spec.

Convert = to :: in type specs

If a type specification uses = instead of ::, then hit Alt+Enter on the = to change it to :: and fix the type spec.

Run Configurations

mix test

The mix test task gets a special type of Run Configuration, Elixir Mix ExUnit. Using this Run Configuration type instead, of the basic Elixir Mix Run Configuration will cause the IDE to attach a special formatter to mix test, so that you get the standard graphical tree of Test Results

Creating mix test Run Configurations Manually

1. Run > Edit Configurations…
2. Click +
3. Select “Elixir Mix ExUnit”
4. Fill in the “Program arguments” with the argument(s) to pass to mix test. Normally, this will be a directory like test, relative to the “Working directory”
5. Fill in the “Working directory”

• Type the absolute path to the directory.
• Select the path using directory picker by clicking the ... button

6. (Optionally) click the ... button on the “Environment variables” line to add environment variables.
7. Click “OK” to save the Run Configuration and close the dialog
8. Click the RUn arrow in the Toolbar to run the mix test task
9. The Run pane will open showing the Test Results

While you can create Elixir Mix ExUnit run configurations manually using the Run > Edit Configurations... menu, it is probably more convenient to use the context menu.

Creating mix test Run Configurations from context

The context menu must know that the the directory, file, or line you are right-clicking is a test. It does this by checking if the current directory or an ancestor is marked as a Test Sources Root.

1. In the Project pane, ensure your OTP application’s test directory is marked as a Test Sources Root
2. Check if the test directory is green. If it is, it is likely a Test Sources Root. This color may differ in different themes, so to be sure you can check the context menu
3. Right-click the test directory.
4. Hover over “Mark Directory As >”
   * If “Unmark as Test Sources Root” is shown, then the directory is already configured correctly, and create from context will work.
   * If “Test Sources Root” is shown, then the directory need to be configured by clicking that entry

Creating/Running mix test Run Configurations from directory

1. Right-click the directory in the Project pane
2. Click “Run Mix ExUnit”, which will both create the Run Configuration and Run it.

• If you want to only create the Run Configuration, select “Create Mix ExUnit” instead

Alternatively, you can use keyboard shortcuts

1. Select the directory in the Project pane.
2. Ctrl+Shift+R will create the Run Configuration and Run it.

Creating/Running mix test Run Configurations from file

1. Right-click the file in the Project pane
2. Click “Run Mix ExUnit”, which will both create the Run Configuration and Run it.

• If you want to only create the Run Configuration, select “Create Mix ExUnit” instead

Alternatively, you can use keyboard shortcuts

1. Select the directory in the Project pane.
2. Ctrl+Shift+R will create the Run Configuration and Run it.

Finally, you can use the editor tabs

1. Right-click the editor tab for the test file you want to run
2. Click “Run Mix ExUnit”, which will both create the Run Configuration and Run it.

• If you want to only create the Run Configuration, select “Create Mix ExUnit” instead

Creating/Running mix test Run Configurations from line

If you want to be able to run a single test, you can create a Run Configuration for a line in that test

1. Right-click a line in the test file
2. Click “Run Mix ExUnit”, which will both create the Run Configuration and Run it.

• If you want to only create the Run Configuration, select “Create Mix ExUnit” instead

Alternatively, you can use keyboard shortcuts

1. Place the cursor on the line you want to test
2. Ctrl+Shift+R will create the Run Configuration and Run it.

Changelog

v4.1.0

Enhancements

• #331 - @KronicDeth
  • Allow do end blocks to fold to do: ...
  • Allow -> operator and the right operand to fold to -> ...
  • Allow @doc, @moduledoc and @typedoc value to fold to "...".
  • Fold runs of adjacent alias, import, require, or use to be followed to a single alias, import, require, or use followed by ....
• #334 - Function separators - @KronicDeth
  • Show a function separator (Preferences > Editor > General > Appearance > Show method separators) above the group of @doc, @spec and def, defp, defmacro, and defmacrop (call definition clauses) of the same name and arity range. Arity range will be used if one of the call definition clauses uses default arguments.
• #337 - @KronicDeth
  • @for folds to the resolved module name in defimpl
  • @protocol folds to the protocol name in defimpl
• #343 - Share code between mix and elixir version parsing. - @KronicDeth
• #344 - @KronicDeth
  • Allow Unknown modulars in the Structure pane, in addition to Go To Symbol. Their icon is a big ? to indicate their correct usage is unknown.
• #348 - @KronicDeth
  • Regenerate gen folder using Grammar Kit 1.4.1 and fix some bugs (including JetBrains/Grammar-Kit#126) manually.
• #349 - Have both QualifiedBracketOperation and UnqualifiedBracketOperation extend BracketOperation, so that BracketOperation can be used to match both when the qualification does not matter. - @KronicDeth
• #364 - @KronicDeth

  • Regenerate parser with GrammarKit 1.4.2

  • ElixirSdkRelease is now Comparable, so version checks can be done for tests to restrict them to Elixir 1.2+ for multiple alias support.

  • Resolve Multiple Aliases with unqualified Alias in tuples.

  • canonicalName borrows from the idea of PsiReference#canonicalText: an element can have both a Name (from getName), which is the literal name in the code, which can be renamed, and a Canonical Name, which is the name to refer to the element without need for imports or aliases. For this change, defimpl, defmodule, and defprotocol will show their full module Alias for their Canonical Name.

    This change addresses the use case of Go To Declaration that should resolved to a nested defmodule.

Bug Fixes

• #330 - Check if parameter is null before Variable#execute call in Variable#execute(PsiElement[], ResolveState). - @KronicDeth
• #336 - Fix isVariable and variableUseScope for var!(name)[...] - @KronicDeth
• #337 - @KronicDeth
  • @for is no longer marked as unresolved in defimpl and instead resolve to the either the <name> in for: <name> or the module name for the enclosing module when for: is not given.
  • @protocol is no longer marked as unresolved in defimpl and instead resolve to the <name> in defimpl <name>.
• #342 - @KronicDeth
  • Instead of assert checkRight || checkLeft in Match#processDeclaraions, do the normal code if checkRight || checkLeft and log an error report otherwise, so that the exact code that trigger this error can be reported and the method fixed to handle that form of Match later.
• #343 - Be able to parse mix version from 1.3.0+ - @KronicDeth
  • Check all lines of output for mix version as Elixir 1.3.0 changed the format of mix --version, so that it includes the Erlang header (Erlang/OTP ... [erts-...] [source] [64-bit] [smp:..:..] [async-threads:..] [hipe] [kernel-poll:false] [dtrace]) on the first line and Mix <version> on the 3rd line. Previously the parsing expected Mix <version> to be the first line.
• #344 - @KronicDeth
  • If no known modular (Module, Implementation, Protocol, Quote, or Use) matches the call, then use Unknown, which accepts any macro with a do block or keyword. This allows Go To Symbol to no error in projects using Dogma as defrule is now treated as Unknown instead of causing an error that the enclosing modular could not be found.
• #349 - BracketOperations are neither parameters nor variables. - @KronicDeth
• #353 - Fix stacktrace linking picking wrong file with same basename - @KronicDeth
  • Strip spaces from front of file path in mix output, which allows file looks to work correctly.
  • Ensure file reference highlight doesn’t include the leading and trailing characters by fix off-by-one errors.
• #358 - Determine whether to check left, right, or both by doing isAncestor checks for all operands, not just the normalized operand. The normalized operand is still used for PsiScopeProcessor#execute since #execute is not expected to handle error elements. - @KronicDeth
• #364 - @KronicDeth
  • Add A.{B, C} to grammar with quoting to check consistence with Elixir 1.2. Ports elixir-lang/elixir#3666.
  • Use fullyQualifiedName instead of getName for resolvableName because fullyQualifiedName is needed so that qualified aliases inside of the { } of a multiple alias will not have a name as getName is null for those qualified aliases because the name from getName has to be a literal name that can be renamed and qualified names can’t be renamed.
• #365 - The Module icon got the same icon as Unknown when creating Unknown somehow, I assume due to find-replace. - @KronicDeth

Bug Fixes

• #454 - Return emptySet when lookupElementByPsiElement is null. - @KronicDeth
• #455 - @KronicDeth

  • Don’t do a naked assert that there are 2 children because this can fail during error recovery on the operand, instead use the prefix.Normalized.operand() through prefix.operand().

    WARNING: This changes the @NotNull array so that its sole element changes from @NotNull to @Nullable. It may trigger new bugs.

• #461 - Use shipped GeneratedParserUtilBase.DUMMY_BLOCK because the DUMMY_BLOCK MUST match the GeneratedParserUtilBase to detect dummy blocks inserted for error handling. - @KronicDeth
• #465 - Skip over ElixirNoParenthesesStrict for isVariable - @KronicDeth

  • Don’t add current call definition clause being written to completion
• #476 - When#leftOperand will return null (because it’s normalized) if there are left-hand error elements, but when stripping guards we want best-effort to match human expectations, so don’t use normalized null, but use left, non-error element if it is unique. - @KronicDeth
• #477 - Highlight types in QualifiedNoParenthesesCall - @KronicDeth
• #478 - Still not obvious why name for a CallDefinitionClause lookup renderer can be longer than presentableText, so still log an error, but with Logger.error, so we get name, presentableText, and the original element. - @KronicDeth
• #479 - @KronicDeth
  • Skip Arguments elements in previousParentExpresion to eliminate an unnecessary level of processing declarations since calls will enter their arguments.
  • Only put new ENTRANCE in ResolveState in variable.MultiResolve.resolveResultList, so that caller can override the default value.
  • Set ENTRANCE to matchAncestor instead of previous expression to eliminate the looping that occurred when a variable was unbound (or a function) because the check for with (and for) was expecting the ENTRANCE to be the previous child expression instead of the with clause as a whole (or the Arguments element as had been the case before 6fcc19b).
• #483 - @KronicDeth
  • Resolves functions qualified by Aliases that are either direct Module references or one-step aliases.
  • Remove Call#resolvedFunctionName because import can’t rename functions.
• #484 - Don’t type-highlight BracketOperations as they occur when putting maps or structs in front of lists. - @KronicDeth
• #485 - Treat Enum.each the same as Enum.map around def - @KronicDeth

v4.5.0

Enhancements

• #452 - @KronicDeth
  • Go To Declaration for functions and macros (only those defined in parseable-Elixir source. References to Erlang functions or only those available in .beam file, such as the standard library will not resolve.)
  • Completion for functions and macros (only those defined in parseable-Elixir source. Erlang functions and Elixir function only in compiled .beam file, such as the standard library will not complete.)
    • Completion uses the same presentation as Structure View, so the you can tell whether the name is a function/macro, whether it is public/private, and the Module where it is defined.
    • Completed functions/macro insert () after the name in preparation for Elixir 1.4 where it is an error to have bare function calls. It also makes it more obvious that you inserted a function and not a variable.
    • Completion works for all functions when a bare identifier is used. For a qualified identifier, only functions/macros under than Module are shown.

README Changes

Completion

Function and Macro Calls

Completion uses the same presentation as Structure, so you can tell whether the name is function/macro (Time), whether it is public/private (Visibility) and the Module where it is defined. Between the icons and the Modules is the name itself, which is highlighted in bold, the parameters for the call definition follow, so that you can preview the patterns required for the different clauses.

526×146 15.2 KB

Qualified

Qualified functions and macro calls will complete using those functions and macros defined in the qualifying Module (defmodule), Implementation (defimpl) or Protocol (defprotocol). Completion starts as shown as . is typed after a qualifying Alias.

Unqualified

Function and macro calls that are unqualified are completed from the index of all function and macro definitions, both public and private. (The index contains only those Elixir functions and macro defined in parsable source, such as those in the project or its dependencies. Erlang functions and Elixir functions only in compiled .beam files, such as the standard library will not complete.) Private function and macros are shown, so you can choose them and then make the chosen function or macro public if it is a remote call.

Go To Declaration

Function or Macro

You’ll know if function or macro usage is resolved and Go To Declaration will work if the call is annotated, which in the default themes will show up as italics.

Imported Functions or Macros

1. Place the cursor over name of the function or macro call.
2. Activate the Go to Declaration action with one of the following:
   1. Cmd+B
   2. Select Navigate > Declaration from the menu.
   3. Cmd+Click
3. A Go To Declaration lookup menu will appear, allowing you to jump to either the import that imported the function or macro or jumping directly to the function or macro definition clause. Select which declaration you want.
   1. Use arrow keys to select and hit Enter
   2. Click

Local Functions or Macros

1. Place the cursor over name of the function or macro call.
2. Activate the Go to Declaration action with one of the following:
   1. Cmd+B
   2. Select Navigate > Declaration from the menu.
   3. Cmd+Click
3. Whether a lookup a Go To Declaration lookup menu appears depends on the number of clauses in the function or macro definition:
   1. If there is only one clause in the function or macro definition, you’ll jump immediately to that clause
   2. If there is more than one clause in the function or macro definition, a Go To Declaration lookup menu will appear, allowing you to jump to either the import that imported the function or macro or jumping directly to the function or macro definition clause. Select which declaration you want.
      1. Use arrow keys to select and hit Enter
      2. Click

Remote Functions or Macros

1. Place the cursor over name of the function or macro call that is qualified by an Alias.
2. Activate the Go to Declaration action with one of the following:
   1. Cmd+B
   2. Select Navigate > Declaration from the menu.
   3. Cmd+Click
3. 1. If there is only one clause in the function or macro definition, you’ll jump immediately to that clause
   2. If there is more than one clause in the function or macro definition, a Go To Declaration lookup menu will appear, allowing you to jump to either the import that imported the function or macro or jumping directly to the function or macro definition clause. Select which declaration you want.
      1. Use arrow keys to select and hit Enter

@KronicDeth Hi i can’t seem to find how to autocomplete builtin modules and functions from them, like Enum, List etc. How can I turn it on?

From the changelog:

only those defined in parseable-Elixir source. Erlang functions and Elixir function only in compiled .beam file, such as the standard library will not complete

So, you aren’t missing anything. The features don’t work on the standard modules because they leverage the .ex/.exs parser currently.

Is there anyway to set a code style specific for Elixir code files?

When I installed this and went to Settings → Code style it does not show Elixir in the list of languages. Elixir is the only language that tries to force me in the 2 space indention that I dislike, but I really don’t feel like fighting things like doctests :-/.

That could be changed though, you can pull call information out of the module_info callback. The atom elixir plugins use that to provide autocomplete (so, consequently, autocomplete does not work until at least one compile is done). A mixing of the two styles would be great for both completeness and up-to-date’ness. ^.^

I’m aware how Alchemist and atom-elixir does completion (with a fork of alchemist-server). It’s just a matter of time and I find using the OpenAPI tools better because the IDE knows how to cache the index and can jump to specific clauses and around errors while alchemist-server (correct me if I’m mistaken) needs at least the file to be error free because it’s using Elixir runtime to reflect on the .beam.

Now that the parseable-code Go To Declaration is complete I’m left with the .beams, but I don’t necessarily have to solve that with alchemist-server. Other solutions:

1. Use JInterface to talk directly instead of using text-based protocol used by alchemist-server (so a fork and maybe a PR to alchemist-server)
2. Use Java to read the .beams directly
3. Decompile .beam (the way IntelliJ does with Java .class) with the option to download source for stdlib.

I like (2) because it means the IDE doesn’t have to run an external process, which requires getting its environment correct too, but it would require more tightly understanding the internal .beam format. (3) isn’t a complete solution because only reflection will get a complete listing when a lot of macro indirection is involved or in the bootstrapped parts of the standard-lib, but it would be cool to have the .beam dissassembler built-in the way it in for Java in IntelliJ.

The Elixir plugin does not support Code Style or Formatting yet. There’s are open issue for Code Style (Code Style Settings · Issue #99 · KronicDeth/intellij-elixir · GitHub) and Formatter (Code Formatter · Issue #98 · KronicDeth/intellij-elixir · GitHub).

You really should try to get used to 2 space indent in Elixir. It’s the idiomatic indentation for Elixir and part of the community style guide (GitHub - christopheradams/elixir_style_guide: A community driven style guide for Elixir · GitHub).

Erlangs JInterface is pretty awesome, low level but awesome.

Each version of erlang can change that, so be careful.
