Add a separate face for exported functions to erlang mode so that they
are distiguishable at a glance. By default, the face is identical to
that of normal functions and there is also a configuration variable to
inhibit the face in case running this on a low-performance machine is
too slow.

Like this: 'atom$'. In that example, the last single quote should be
recognised as ending the atom. This needs a font-lock workaround
similar to the one for strings.

In some situations, the indentation of record fields in Emacs was
strange. This example below shows how Emacs previously would indent
two similar pieces of code very differently:
some_function_with_a_very_long_name() ->
#'a-long-record-name-like-it-sometimes-is-with-asn.1-records'{
field1=a,
field2=b}.
x() ->
#some_record_name{
field1=a,
field2=b}.
This changes the indentation to be like below for both cases:
some_function() ->
#some_record{
field1=a,
field2=b}.

The purpose of this regexp is to ensure that, when invoking the Erlang
compiler inside Emacs through M-x compile, any error messages be
turned into links jumping to the right line in the right source file.
However, it seems like this works out of the box in modern Emacsen,
and furthermore, using a non-standard regexp inhibits jumping to a
certain column when this is provided by the compiler.

Package.el and Emacs package repositories (like ELPA or Marmalade
place some requirements onto packages which are uploaded to them. This
commit does minor cosmetic changes which makes it easier to create
appropriate package file for those repositories.

Update erlang-flymake to recognize the "deps" folder as an include
directory. This makes erlang-flymake compatible with the rebar
dependency management tool's default folder structure, which puts
included dependencies in "deps". Considered additionally adding
deps/*/include, deps/*/ebin, and deps/*/src as include directories,
but erlc's -I command line option does not support wildcards.

If visiting a .yrl or .xrl file in emacs with erlang-mode,
then the `erlang-compile' function (normally bound to C-c C-k),
now knows how to compile yecc and leex files, and then, if that
compilation succeeds, also compiles the resulting .erl files.
Also introduce a `erlang-compile-command-function-alist'
to make it possible to hook in other functions for computing
compilation commands/expressions, depending on file name.

The Erlang mode for Emacs inserts a newline after every "->", which
saves you one keystroke when writing a function, but that is
inappropriate when writing a type spec, as you'd normally keep the
spec on one line. This change inhibits the automatic insertion when
the current line starts with "-spec" or "-type".

Emacs has a facility for setting options on a per-file basis based on
comments in the source file. By default, all options are considered
"unsafe", and the user is queried before the variable is set. This
patch declares the variables erlang-indent-level, erlang-indent-guard
and erlang-argument-indent to be safe, if the value specified in the
source file is valid.
Such declarations usually look like this:
%% -*- erlang-indent-level: 2 -*-
and appear on the first line of the file.

A string whose last character is a dollar sign used to make the syntax
highlighter believe that the string never ends, breaking highlighting
of following code:
-vsn("$Revision: 42 $").
And the double quote as a character constant with a (superfluous)
backslash used to make the syntax highlighter believe that a new
string started:
foo() ->
$\".
This change fixes both problems by adding two regexps to
font-lock-syntactic-keywords in erlang-font-lock-init.
One case that is still broken is when a multi-line string ends with a
dollar sign:
bar() ->
"This multi-line string
ends with a $".
baz() ->
this_gets_incorrectly_highlighted.

Follow the GNU recommendation of not introducing runtime
dependencies on the Common Lisp package in ELisp packages
that will be distributed for widespread use.
In practice this means it's ok to use cl macros but not
functions.

This determines the most recent invocation of EUnit and runs it
again -- whether one test or all tests in a module were run (and
if all a module's tests were run, whether cover compilation was
involved). This can be especially handy when one test is being
run repeatedly, eliminating the need to position the cursor in
the desired test just to run it.
Default keybinding: C-c C-e l

If the variable 'erlang-eunit-autosave' is non-nil, buffers will be
automatically saved just before running tests -- the "Do you want
to save?" prompt will be inhibited. This can be useful, reducing the
save-compile-load-test cycle to just one keychord.
|
|
Add a number of features to the emacs mode which make it easier to
work with eunit test cases while keeping track of code coverage.
* C-cC-ec:
Compile the module under test for code coverage analysis, run tests
and show the results of the coverage analysis in a new buffer.
* C-c-C-ev:
Compile the current module for code coverage analysis.
* C-cC-ea:
Show the results of the coverage analysis in a new buffer.

Previously there were only two options: either the EUnit test file was
placed directly within the test directory or within the same directory
as the source file. Now a list of candidate locations are supported.
This way more than two alternative locations are supported as well as
arbitrarily deep directory structures (i.e. test/eunit/x_tests.erl).
The default behaviour is still the same, but it's possible to specify
locations by setting the following two variables:
erlang-eunit-src-candidate-dirs
erlang-eunit-test-candidate-dirs

* dgud/emacs-catch-improvements:
Improved indentation of old catch.
Added more type highlighting and fixed record indentation with types.
|

An example that didn't work previously.
case Foo of
{ok, X} ->
ok;
_ ->
catch file:close(FD)
end.

Type highlighting reported by Jay Nelson
non_neg_integer() will highlight purple but pos_integer() does not.
Closing record indentation problem reported by Maxim Treskin:
-record(state, {
sequence_number = 1 :: integer()
}).
|
|
|
|
|
|
Hopefully this covers at least some of the common cases and makes the
flymake support more usable as is. The purpose of including the ebin
directory is to support things like behaviours and parse transforms.

Create and assign the erlang-mode keymap to erlang-mode-map once
erlang.el is loaded, not the first time it is used. This way of doing
it follows the Emacs Lisp convention described at
http://www.gnu.org/software/emacs/manual/html_node/elisp/Tips-for-Defining.html
and also makes it easier for users to customize the keymap.
Remove the now unneeded functions erlang-keymap-init and
erlang-mode-commands.
Also move the definition of inferior-erlang-use-cmm, so it is
available when defining erlang-mode-map.
|
|
Make the function names used by M-x imenu contain the function arity
as well as the name. This makes it possible to jump to all functions
of the same name, as opposed to only the one that is defined first.
For example, in the following module there is now a way to jump
directly to foo/1:
-module(foo).
foo() ->
ok.
bar() ->
error.
foo(A) ->
{ok, A}.
|
|
Trying to indent this piece of code by hitting TAB on each line:
foo() ->
[#foo{
foo = foo}].
used to cause an error. Fix by ignoring errors when trying to skip
backwards from a record.
Also add this test case to test.erl.orig and test.erl.indented.
|
|
Add a new feature to the command inferior-erlang: when called with a
prefix argument, prompt for the command to execute to start the Erlang
shell. When possible (i.e., in Emacs 23 and later), allow tab
completion as in a normal shell.
Also create the shell buffer in such a way that, if
uniquify-buffer-name-style is not nil and several Erlang shell buffers
are started in different directories, the names of those buffers
reflect their working directories instead of being *erlang*,
*erlang*<2>, etc.
|
|
A file whose first line contains "#!/usr/bin/env escript" should be
opened in erlang-mode, even if its name doesn't end in ".erl". Add an
entry to interpreter-mode-alist to that effect.
|
|
This determines the current test function under point (cursor), whether the active buffer
contains a test module (foo_tests) or the module itself (foo), then compiles the source
module (and test module if present) and runs that test function.
Since this added a third testing feature, there was some natural duplication that needed
to be factored out. The notion of 'compile and run tests' was decoupled from exactly
which tests should be run. The definitions of default keybindings were converted to a list
for clarity and conciseness.
