Erlang IDE

Erlang plugin

Erlang Plugin turns IntelliJ IDEA and other IntelliJ-based products (RubyMine, PyCharm, WebStorm, etc.) to a convenient Erlang IDE.

Pre-release builds

Download the latest successful plugin, hit 'Install plugin from disk...' at 'Plugins' page in 'Settings' of your IDE, and point it to the downloaded archive.

Note for Mac OS X users: you need to download the entire zip file, not a several jars (see Apple discussion forum).

Recent changes

The latest version

• IntelliJ 2021.2 support
• Erlang plugin could be installed and upgraded without restart

intellij-erlang's Issues

Add autocomplete for module names

more formatting errors

%1 extra space
-export_types([x/0, y/1]).

% brace extra tab
f() ->
    X = f(
        alpha,
        beta
    ).

%3 detab
-spec using(Module, Params, Callback) -> term() when
    Module :: module(),
    Params :: term(),
    Callback :: fun().

Atoms in module directive cause error highlights.

For example,

-module('ELDAPv3').

is valid. Yet plugin/idea complains that the file shoudl be declared in file named in a certain way, indicating an error in code.

This is in the latest 0.3 plugin.

Create project from source does not work

When I try to "create a project from source" and give it my Elang application directory as an input Idea claims that it finds nothing familiar in there.

P.S. Excited to see you plugin grow into a full-fledged language support. Keep up the good work.

Syntax support for config-like files

E.g. app files, rebar.config etc.

Basically, this means that Erlang file could start with tuple.

'fun' function references aren't considered usages

In the following updater is marked as unused.

-module(foo).

-export([bar/0]).

updater() ->
    ok.

foo(Func) ->
    Func().

bar() ->
    foo(fun updater/0).

ignore unused functions

eunit functions are exported by eunit parse_transform

it would be good to have ignore setting with regexp matches for unused symbols inspection for such cases.

add autocomplete record fields

Emacs style code formatting

Emacs code formatter is both de facto and de jure the industry standard. I believe that people will be more eager to move to your IDE if it formats the code the way they used to.

Support for IntelliJ 12 EAP

The plugin is greyed-out, not compatible with the latest EAP version of IntelliJ IDEA.

Extra comma in tuple syntax error showing in wrong place

This may be an edge case, but it confused me for a few minutes this morning.

The following code has a syntax error on line 14 (an extra comma after final tuple), but the plugin incorrectly flags the error as on line 12 and line 10. The erlang compiler gives me an error on line 14.

-module(foo).

-export([bar/0]).

-record (rec, { something }).

foo(Blah) -> Blah.

bar() ->
    F = fun({ Eep }) ->
        ok,
        #'rec'{ something = Eep } = Eep#'rec'.something,
        blah,
        foo([{a}, {b},])
    end,
    F.

Basic Rebar support

Please consider introducing Rebar support by that I mean:

• Create project from external model should be able to parse the rabar.config file and create project layout based on it.
• erl_opt from the rebar.config should be applied during compilation.
• Dependencies defined in rebar config should be properly added to the libs project section, automatically retreived if missing, indexed to be available for code completion, and be used during compilation.

Nested records highlighted as errors

Imagine that we have the following record definitions:

-record(nrec0, {name = "nested0"}).
-record(nrec1, {name = "nested1", nrec0=#nrec0{}}).
-record(nrec2, {name = "nested2", nrec1=#nrec1{}}).

Since R14 it is allowed to write:

N2 = #nrec2{},
"nested0" = N2#nrec2.nrec1#nrec1.nrec0#nrec0.name,
N0n = N2#nrec2.nrec1#nrec1.nrec0#nrec0{name = "nested0a"},

But the second and all the following '#' are highlighted as errors.

formatting errors round 3

-attr([x / 1, y / 2]).

-spec f/2 :: (atom(),
    atom()) -> term().

f(A, B) when is_list(A), is_list(B);
    is_binary(A), is_binary(B) ->
    f().

f(A, B) 
    when is_list(A), is_list(B);
    is_binary(A), is_binary(B) ->
    f().

-include and -include_lib directives are not supported

Records from included headers are claimed as unresolved

no module settings can be seen in erlang module but name. (0.2.0)

Cant configure source root, etc.

Create project from existing sources doesn't work.

completion does not work from the middle

If press ctrl+space on blank line it shows bunch of variants. if press it in the middle of the word it shows completion for keywords only.

http://s9.postimage.org/ih9iuveul/erlang_no_suggest.png

Type definition by U..L is syntax error highlight

I have a code:
-type(my_cell() :: 1..7).

The plugin (ver 0.2.5) highlight the 1..7 (dots) and says ')' or '|', got expected but '..'
The Erlang compiler is ok.

Add color settings page

Cannot Detect SDK Version

On both Linux CentOS and OSX Mountain Lion, when attempting to add Erlang SDK, get an error saying that "Cannot Detect SDK Version" - "Probably SDK installed in '/opt/local/installs/erlang' is corrupt"

The version is not corrupt, works just fine.

The problem went away, when selected ' /opt/local/installs/erlang/lib/erlang/' instead. Without explicit documentation of such, it is difficult to know and guess that this is the directory that needs to be provided in order for it to work.

Included record incorrectly highlighted as error

The last line has the record name highlighted with the error "Unresolved record 'msg_full_object'".

foo.hrl:

-record(msg_full_object, { action }).

foo.erl:

-module(foo).
-include("foo.hrl").
-export([foo/0]).
foo() -> #'msg_full_object'{ action = undefined }.

Supports macros

Resolve, rename, go to declaration, safe delete.

Rewrite warning annotations using intentions

parse errors in binary comprehensions

these correct lines are red

<< <<X>> || <<X>> <= <<"abc">>>>

<< <<B:8>> || B <- [1,2,3] >>

-callback Doesn't work

All variables marked "Unresolved". I've made the screenshot to illustrate what I mean.

Support for quick help (Ctrl+Q) for standard functions

When I press Ctrl+Q on a module or a function name a window should open with documentation on the subject. That works only for methods and functions defined in my project, but not for those defined e.g. in stdlib.

Type specification is highlighted as error

If a function type specification contains when clause then the first word after it is highlighted as error. E.g.:

-spec expect(Mod, Func, Expect) -> ok when
      Mod :: atom() | [atom()],              % <-- Mod is highlighted as an error
      Func :: atom(),
      Expect :: StubFun | [ClauseSpec],
      StubFun :: fun(),
      ClauseSpec :: {ArgPatterns, RetSpec},
      ArgPatterns :: [term() | '_'],
      RetSpec :: term() | ret_spec().

Add Integrated Testing

Just like RubyMine, I'm pretty sure you know exactly what I mean :)

I wish support was added for:

• specific single test
• all tests related to a module
• common tests
• dialyzer

r.

'<=' highlights as error

fun M:F/A does not work right

When you define a fun as fun M:F/A then it is highlighted as error. If we have:

-module(mod1).
-export([func1/0]).
func1() -> ok.

Then:

-module(mod2).
func2() -> ok.
error_here() ->
    F1 = fun mod1:func2/0,    % no error here (probably because func2 is defined in this module), but it should be since no func2 in mod1. 
    F2 = fun mod1:func1/0.    % func1/0 is highlighted as error, but it should not.

Note that in place of explicit module and function names it should be possible to use Variables and Marcos. e.g. fun Mod:Func/Arity and fun ?MOD:?FUNC/?ARITY.

Predefined macros are not respected

There is a number of macros that are predefined for every module, e.g. MODULE, LINE, etc. (for a complete list please refer to http://www.erlang.org/doc/reference_manual/macros.html#id80541). They are highlighted as errors now.

IDEA chokes on exprecs.erl

It appears easy to reproduce.

git clone git://github.com/esl/parse_trans.git

Then create new project out of the cloned repo.

Open file src/exprecs.erl

At this point IDEA starts spinning CPU and further interactions with it are pointless.

almost forgot to mention: on mac IDEA 11.1

alphabetical order in ctrl+F12

It would be good functions in ctrl+F12 to be sorted alphabetically

Add autocomplete and resolve for BIFs

For further information see /usr/lib/erlang/lib/stdlib-1.17.3/src/erl_internal.erl

Tab autocomplete doesn't overwrite entire function

Put your cursor after the 'f' in 'foo' in the export statement and press ctrl-space. Hit tab to accept and overwrite the selected completion. It doesn't overwrite the complete function and leaves 'foo/0/0'.

-module(foo).

-export([foo/0]).

foo() ->
    ok.

unused variable highlight errors in comprehension

http://s10.postimage.org/dl76ed207/erlang_unused.png

1,3 variables are actually used.
2. should be marked as unbound variable but it's not highlighted in first perform and is erroneously highlighted as unused in second

-module(x).

-export([perform/2]).

perform(X, Y) ->
    Z = X ++ "X",
    [error_m ||
        f(Z, EbinProdDir, Y),
        m:f(Z, m:v(Y), EbinProdDir)
    ].

perform(X, Y) ->
    Z = X ++ "X",
    [error_m ||
        f(Z, EbinProdDir, Y)
    ].

Duplicate function not marked as error

Second foo is an error.

-module(foo).
-export([foo/0]).

foo() ->
    ok.

foo() ->
    ok.

Supports auto indentation

It would be very usable to set a cursor after Enter pressed and separate menu item "Format code".

Settings/Code Style/Erlang format doesnt look working

settings doesn't have effect. Example - unchecking setting 'Space around assignment" doest actually reformat that way.

Another point this option is not really correct regarding erlang syntax because of

X=<<"a">>.

is syntactically illegal. So having in unchecked will introduce compilation errors for

X = <<"a">>.

formatting errors

All this examples will be "detabbed".

-module(format_errors).

-export([comprehension/0,
    record/0]).

-spec f/1 :: (atom()) ->
    atom().

comprehension() ->
    [X ||
        Y <- [1,2,3],
        X <- Y
    ].


record() ->
    #x{
        a = 1,
        b = 2
    }.

Create live templates for popular behaviours

Will be cool to create a predefined code fragments for some popular behaviours, e.g. gen_server.
At the moment we have three file templates: empty module, OTP application and OTP gen_server
So the issue is: need to create velocity templates for some useful behavious.
Please, see commit below and http://www.jetbrains.com/idea/webhelp/live-templates.html for futher information.

escript support

add support for

!/usr/bin/env escript

Single period doesn't highlight as error

This should be shown as a syntax error.

-module(foo).

.

'orelse' and 'andalso' doesn't highlights as erlang construction

Compile to ebin directory

It seems that it only wants to compile to "Project Compiler Output" directory with production/test subdirectories. It would be fantastic if it compiled to ebin directory

Create a custom WordScanner for FindUsageProvider

For further information please see example from #21.

Add warnings for unusable variables, functions and for other

Add 'New Erlang File' action

Code Reformatting

I'd be nice to have a way to automatically indent code in a module, on a single key press (again, RubyMine docet).
