Follow the same pattern as pid_to_list

All of those are present on the target Emacs 24.1.

This commit removes some compatibility for old GNU Emacs releases
and XEmacs. erlang-mode didn't really work on them for a while now,
so this is just a cleanup, nothing actually changes.
It's part of the ongoing effort to clean up and modernize the codebase
of erlang-mode.
|
|
Only the xref front-end introduced in Emacs 25 consider arity. It is
not implemented for older emacsen.
Look for manual page files in lib/erlang/man in erlang-root-dir. Also
do not give up in erlang-man-module when not finding the manual page
file. Call manual-entry as a fallback.
Do not bother to populate menu-bar with man pages when menu-bar-mode
is nil.
Add erlang extensions also to dired-omit-extensions.
Remove some support for Emacs 18 and 19.

* maint:
Add an option erlang-icr-indent
|
|
The option makes it possible to customize the indention of
if/case/recieve patterns.
Before the change, the indentation of 'if' patterns is 3 steps and
'case' patterns is 4 steps. It cannot be changed alone. Some people
prefer other styles, for example, zero indentation.
case a of
true ->
do_something();
false ->
do_something_else()
end.
This patch just adds an option `erlang-icr-indent'. Its default value is
`nil' which means keeping the legacy behavior. When non-nil, the
pattens of if/case/receive are indented according to
`erlang-icr-indent'. "(setq erlang-icr-indent 0)" will keep
if/case/receive at the same column of the sub-clauses.

New commands to ease looking up OTP documentation

- erldoc-browse: open the manual entry for an MFA in the browser
- erldoc-apropos: list MFAs containing a substring
- erldoc-browse-topic: open user guides in the browser

Fix whitespace setting in test files
Avoid some error reports when stopping mnesia
wx: Improve error handling
Fix all whitespace-related issues in erlang.el
mnesia: Fix double blocked tables which could cause a crash
wx: Add wxWindow:getContentScaleFactor
|
|
Having a consistent whitespace usage in the source makes it easier for
future contributors to send patches. This commit does the following:
* Replace tabs with spaces
* Kill trailing whitespace
* Disable indent-tabs-mode for erlang.el to prevent tabs from creeping
in

- EDoc comment indentation

erlang-mode: do not configure require-final-newline

* dgud/emacs/do-not-require-final-newline/PR-1130:
erlang-mode: do not configure require-final-newline
|
|
Implement as ceil/1 and floor/1 as new guard BIFs (essentially part of
Erlang language). They are guard BIFs because trunc/1 is a guard
BIF. It would be strange to have trunc/1 as a part of the language, but
not ceil/1 and floor/1.
|
|
The syntax was limited to atoms, strings and 2-tuples. This covers most
compile options but not for example {d,Macro,Value}.
Add support for N-tuples and lists.
Add a related unit test case.
|
|
Lambda advice cannot easily be updated.
|

Completion in erlang shell buffer only works in Emacs 25.
Minor cleanup of completion stuff.
Add test-case for completion at point.
Avoid inf-loop in erlang-end-of-clause when buffer starts with
whitespace.
|
|
Erlang source files do not require a final newline. Thus,
require-final-newline is a personal setting and should not be configured
in the major mode. Setting it here will also negatively impact helpers
like ethan-wspace.
|
|
Adapt tag completion for changes in Emacs 25.
Stop storing module:tag entries in the completion table for definitions
in hrl-files. These entries make no sense since hrl-files are not
modules.
Add test-case for tag completion in erlang-test.el.
Ensure prog-mode is defined for the sake of Emacs 23 and XEmacs.
|
|
Add current module to non external functions calls.
Also improves finding record and macro definitions.
|
|
The right order is defined by find-tag-tag-order which is a list of
predicate functions. Tags matched by the first function shall be
visited first. After that tags matched by the seconds function shall be
visited and so on.
Previous behavior was to visit tags that match any of the functions in
the order they appear in the TAGS file.

* dgud/tools/emacs-xref/PR-1051:
Add xref support in erlang.el
Conflicts:
lib/tools/emacs/erlang.el
|
|
In GNU Emacs 25 xref will be introduced. It is a framework for cross
referencing commands, in particular commands for finding definitions.
It does not replace etags. It rather resides on top of it and
provides user-friendly commands. The idea is that the user commands
should be the same regardless of what back-end does the actual finding
of definitions.
Add to the xref commands awareness of the module:tag syntax in a
similar way that is already done for the old etags commands.
Xref completion support is not included in this commit.
Remove all compilation warnings for GNU Emacs 24.5 and current 25
(4ffec91).
Remove XEmacs incompatibility in
erlang-font-lock-exported-function-name-face.
Add file erlang-test.el with a single unit test.
Add TAGS to .gitignore.

Inside type specs, line-initial commas shall align with open curly
braces. This also applies to record definitions with type specs for
the fields.
For example:
-type foo() :: { a :: integer()
, b :: integer()
}.
For type specs for functions, the commas shall align with the opening
parenthese. So do a closing parenthese when put on a new line.
For example:
-spec foo( X :: integer()
, Y :: integer()
) -> integer().
This does not affect coding styles that don't put commas at the
beginning of lines.

* erlang/pr/1006:
Use define-derived-mode to define erlang-mode
|
|
Remove some things that define-derived-mode does for us.
Also, derive erlang-mode from prog-mode, so that a user that has added
customizations meant for all programming language major modes will
enjoy those in Erlang mode as well.
|

In the Emacs Erlang mode, typing "->" will usually automatically add a
newline, which is usually what you want when writing a function, but
not when writing a type spec. Therefore, there is a check for not
adding the newline when the current line starts with -spec or -type.
This change adds -callback to that check, since it is usually written
the same way as type specs.

Fix "Unbalanced parentheses" error when indenting particular map
constructs. Add new test cases for this fix.
To prevent infinite looping when the programmer mistakenly enters
incorrect syntax, detect cases where erlang-partial-parse fails to
advance when called within a loop, and raise an "Illegal syntax"
error.
|
|
The tag completion code was changed in GNU Emacs 23.1 in a way that
broke erlang.el tag completion. This commit fix that for Emacs 23.1 and
later.
Add progress report while building completion table.
Add completion of module_info/0 for all modules.
Add lib/tools/emacs/*.elc to .gitignore.

The dummy BIF exports 'erlang:bitstr_to_list/1' and 'erlang:list_to_bitstr/1'
seem to have appeared as a result of a copy-paste error and are now removed.
