E.g., assume the path is <c>["/usr/lib/erl", "/usr/local/lib/otp/legacy/ebin", "/home/barney/erl"]</c>. - Then, the code for a module named <c>foo.bar.fred</c> will be - searched for - first as <c>"/usr/lib/erl/foo/bar/fred.beam"</c>, then - <c>"/usr/local/lib/otp/legacy/ebin/foo/bar/fred.beam"</c> - and lastly <c>"/home/barney/erl/foo/bar/fred.beam"</c>. - A module - like <c>lists</c>, which is in the top-level package, - will be looked for as <c>"/usr/lib/erl/lists.beam"</c>, - <c>"/usr/local/lib/otp/legacy/ebin/lists.beam"</c> and - <c>"/home/barney/erl/lists.beam"</c>.</p> - <p><em>Programming</em></p> - <p>Normally, if a call is made from one module to another, - it is assumed that the - called module belongs to the same package as the source module. - The compiler - automatically expands such calls. E.g., in:</p> - <code type="none"> --module(foo.bar.m1). --export([f/1]). - -f(X) -> m2:g(X).</code> - <p><c>m2:g(X)</c> becomes a call to <c>foo.bar.m2</c> - If this is not what was intended, the call can be written - explicitly, as in</p> - <code type="none"> --module(foo.bar.m1). --export([f/1]). - -f(X) -> fee.fie.foe.m2:g(X).</code> - <p>Because the called module is given with an explicit package name, - no expansion is done in this case.</p> - <p>If a module from another package is used repeatedly in a module, - an import declaration can make life easier:</p> - <code type="none"> --module(foo.bar.m1). --export([f/1, g/1]). --import(fee.fie.foe.m2). - -f(X) -> m2:g(X). -g(X) -> m2:h(X).</code> - <p>will make the calls to <c>m2</c> refer to <c>fee.fie.foe.m2</c>. - More generally, a declaration <c>-import(Package.Module).</c> - will cause calls to <c>Module</c> - to be expanded to <c>Package.Module</c>.</p> - <p>Old-style function imports work as normal (but full module - names must be - used); e.g.:</p> - <code type="none"> --import(fee.fie.foe.m2, [g/1, h/1]).</code> - <p>however, it is probably better to avoid this form of import - altogether in new - code, since it makes it hard to see what calls are really "remote".</p> - <p>If it is necessary to call a module in the top-level package - from within a - named package, the module name can be written either with an - initial period as - in e.g. "<c>.lists</c>", or with an empty initial atom, as in - "<c>''.lists</c>". - However, the best way is to use an import declaration - - this is most obvious to - the eye, and makes sure we don't forget adding a period somewhere:</p> - <code type="none"> --module(foo.bar.fred). --export([f/1]). --import(lists). - -f(X) -> lists:reverse(X).</code> - <p>The dot-syntax for module names can be used in any expression. - All segments must - be constant atoms, and the result must be a well-formed - package/module name. - E.g.:</p> - <code type="none"> -spawn(foo.bar.fred, f, [X])</code> - <p>is equivalent to <c>spawn('foo.bar.fred', f, [X])</c>.</p> - <p><em>The Erlang Shell</em></p> - <p>The shell also automatically expands remote calls, - however currently no - expansions are made by default. - The user can change the behaviour by using the <c>import/1</c> - shell command (or its abbreviation <c>use/1</c>). E.g.:</p> - <pre> -1> <input>import(foo.bar.m).</input> -ok -2> <input>m:f().</input></pre> - <p>will evaluate <c>foo.bar.m:f()</c>. - If a new import is made of the same name, - this overrides any previous import. - (It is likely that in the future, some - system packages will be pre-imported.)</p> - <p>In addition, the shell command <c>import_all/1</c> - (and its alias <c>use_all/1</c>) - imports all modules currently found in the path for a given - package name. E.g., - assuming the files "<c>.../foo/bar/fred.beam</c>", - "<c>.../foo/bar/barney.beam</c>" - and "<c>.../foo/bar/bambam.beam</c>" can be found from our current - path,</p> - <pre> -1> <input>import_all(foo.bar).</input></pre> - <p>will make <c>fred</c>, <c>barney</c> and <c>bambam</c> - expand to <c>foo.bar.fred</c>, - <c>foo.bar.barney</c> and <c>foo.bar.bambam</c>, respectively.</p> - <p>Note: The compiler does not have an "import all" directive, for the - reason that Erlang has no compile time type checking. - E.g. if the wrong search - path is used at compile time, a call <c>m:f(...)</c> - could be expanded to <c>foo.bar.m:f(...)</c> - without any warning, instead of the intended - <c>frob.ozz.m:f(...)</c>, if - package <c>foo.bar</c> happens to be found first in the path. - Explicitly - declaring each use of a module makes for safe code.</p> - </description> -</erlref> - diff --git a/lib/kernel/doc/src/ref_man.xml b/lib/kernel/doc/src/ref_man.xml index 9ef0959271..96604a2fa2 100644 --- a/lib/kernel/doc/src/ref_man.xml +++ b/lib/kernel/doc/src/ref_man.xml @@ -4,7 +4,7 @@ <application xmlns:xi="http://www.w3.org/2001/XInclude"> <header> <copyright> - <year>1996</year><year>2009</year> + <year>1996</year><year>2013</year> <holder>Ericsson AB.

(simultaneous connect where B's name is - greater than A's) -not_allowed: The connection is disallowed for some (unspecified) security - reason. -alive: A connection to the node is already active, which either means - that node A is confused or that the TCP connection breakdown - of a previous node with this name has not yet reached node B. - See 3B below. - -This is the format of the status message: - -+---+-------+-------+-...-+-------+ -|'s'|Status0|Status1| ... |StatusN| -+---+-------+-------+-...-+-------+ - -'s' is the message tag -Status0 ... StatusN is the status as a string (not terminated) - -3B) send_status/recv_status: If status was 'alive', node A will answer with -another status message containing either 'true' which means that the -connection should continue (The old connection from this node is broken), or -'false', which simply means that the connection should be closed, the -connection attempt was a mistake. - -4) recv_challenge/send_challenge: If the status was 'ok' or 'ok_simultaneous', -The handshake continues with B sending A another message, the challenge. -The challenge contains the same type of information as the "name" message -initially sent from A to B, with the addition of a 32 bit challenge: - -+---+--------+--------+-----+-----+-----+-----+-----+-----+-----+-----+--- -|'n'|Version0|Version1|Flag0|Flag1|Flag2|Flag3|Chal0|Chal1|Chal2|Chal3| -+---+--------+--------+-----+-----+-----+-----+-----+-----+-----+-----+--- - ------+-----+-...-+-----+ - Name0|Name1| ... |NameN| - ------+-----+-... +-----+ - -Where Chal0 ...
