- SRFI 29: Localization
-
- <H1>Author</H1>
-
- Scott G. Miller
-
- <H1>Abstract</H1>
-
- This document specifies an interface to retrieving and
- displaying locale sensitive messages. A Scheme program can
- register one or more translations of templated messages, and
- then write Scheme code that can transparently retrieve the
- appropriate message for the locale under which the Scheme
- system is running. <br>
-
-
- <H1>Rationale</H1>
-
- <p>As any programmer that has ever had to deal with making his
- or her code readable in more than one locale, the process of
- sufficiently abstracting program messages from their
- presentation to the user is non-trivial without help from the
- programming language. Most modern programming language
- libraries do provide some mechanism for performing this
- separation.</p>
-
- <p>A portable API that allows a piece of code to run without
- modification in different countries and under different
- languages is a must for any non-trivial software project.
- The interface should separate the logic of a program from
- the myriad of translations that may be necessary.</p>
-
- <p>The interface described in this document provides such
- functionality. The underlying implementation is also allowed to
- use whatever datastructures it likes to provide access to the
- translations in the most efficient manner possible. In
- addition, the implementation is provided with standardized
- functions that programs will use for accessing an external,
- unspecified repository of translations.</p>
-
- <p>This interface <i>does not</i> cover all aspects of
- localization, including support for non-latin characters,
- number and date formatting, etc. Such functionality is the
- scope of a future SRFI that may extend this one.</p>
-
- <H1>Dependencies</H1>
-
- An SRFI-29 conformant implementation must also implement
- SRFI-28, Basic Format Strings. Message templates are strings
- that must be processed by the <tt>format</tt> function
- specified in that SRFI.
-
- <H1>Specification</H1>
-
- <h3>Message Bundles</h3>
-
- <p>A Message Bundle is a set of message templates and their
- identifying keys. Each bundle contains one or more such
- key/value pairs. The bundle itself is associated with a
- <i>bundle specifier</i> which uniquely identifies the
- bundle.</p>
-
- <h3>Bundle Specifiers</h3>
-
- <p>A Bundle Specifier is a Scheme list that describes, in order
- of importance, the package and locale of a message bundle.
- In most cases, a locale specifier will have between one
- and three elements. The first element is a symbol denoting the
- package for which this bundle applies. The second and third
- elements denote a <i>locale</i>. The second element (first
- element of the locale) if present, is the two letter, ISO 639-1
- language code for the bundle. The third element, if present, is
- a two letter ISO 3166-1 country code. In some cases, a
- fourth element may be present, specifying the encoding used for
- the bundle. All bundle specifier elements are Scheme
- symbols.</p>
-
- <p>If only one translation is provided, it should be designated
- only by a package name, for example <tt>(mathlib)</tt>. This
- translation is called the <i>default</i> translation.</p>
-
- <h3>Bundle Searching</h3>
-
- <p>When a message template is retrieved from a bundle, the
- Scheme implementation will provide the locale under which the
- system is currently running. When the template is retrieved,
- the package name will be specified. The Scheme system should
- construct a Bundle Specifier from the provided package name and
- the active locale. For example, when retrieving a message
- template for French Canadian, in the <tt>mathlib</tt> package,
- the bundle specifier '<tt>(mathlib fr ca)</tt>' is used. A
- program may also retrieve the elements of the current locale
- using the no-argument procedures:</p>
-
- <p><b><a name="current-language"></a><tt>current-language</tt></b> <tt>->
- <i>symbol</i></tt><br>
- <tt><b>current-language</b> <i>symbol</i> ->
- undefined</tt><br>
- </p>
-
- <blockquote>
- When given no arguments, returns the current ISO 639-1
- language code as a symbol. If provided with an
- argument, the current language is set to that named by the
- symbol for the currently executing Scheme thread (or for the
- entire Scheme system if such a distinction is not possible).
-
- </blockquote>
-
- <p><b><a name="current-country"></a><tt>current-country</tt></b> <tt>->
- <i>symbol</i></tt><br>
- <tt><b>current-country</b> <i>symbol</i> ->
- undefined</tt><br>
- </p>
-
- <blockquote>
- returns the current ISO 3166-1 country code as a symbol.
- If provided with an argument, the current country is
- set to that named by the symbol for the currently executing
- Scheme thread (or for the entire Scheme system if such a
- distinction is not possible).
- </blockquote>
-
- <p><b><a name="current-locale-details"></a><tt>current-locale-details</tt></b> <tt>-> <i>list of
- symbol</i></tt>s<br>
- <tt><b>current-locale-details</b> <i>list-of-symbols</i> ->
- undefined</tt><br>
- </p>
-
- <blockquote>
- Returns a list of additional locale details as a list of
- symbols. This list may contain information about
- encodings or other more specific information. If
- provided with an argument, the current locale details are set
- to those given in the currently executing Scheme thread (or
- for the entire Scheme system if such a distinction is not
- possible).
- </blockquote>
-
- <p>The Scheme System should first check for a bundle with the
- exact name provided. If no such bundle is found, the last
- element from the list is removed and a search is tried for a
- bundle with that name. If no bundle is then found, the list is
- shortened by removing the last element again. If no message is
- found and the bundle specifier is now the empty list, an error
- should be raised.</p>
-
- <p>The reason for this search order is to provide the most
- locale sensitive template possible, but to fall back on more
- general templates if a translation has not yet been provided
- for the given locale.</p>
-
- <h3>Message Templates</h3>
-
- <p>A message template is a localized message that may or may
- not contain one of a number of formatting codes. A message
- template is a Scheme string. The string is of a form that can
- be processed by the <tt>format</tt> procedure found in many
- Scheme systems and formally specified in SRFI-28 (Basic Format
- Strings).</p>
-
- <p>This SRFI also extends SRFI-28 to provide an additional
- <tt>format</tt> escape code:</p>
-
- <blockquote>
- <tt>~[n]@*</tt> - Causes a value-requiring escape code that
- follows this code immediately to reference the [N]'th
- optional value absolutely, rather than the next unconsumed
- value. The referenced value is <i>not</i> consumed.
- </blockquote>
- This extension allows optional values to be positionally
- referenced, so that message templates can be constructed that
- can produce the proper word ordering for a language.
-
- <h3>Preparing Bundles</h3>
- Before a bundle may be used by the Scheme system to retrieve
- localized template messages, they must be made available to the
- Scheme system. This SRFI specifies a way to portably
- define the bundles, as well as store them in and retrieve them
- from an unspecified system which may be provided by resources
- outside the Scheme system.<br>
-
-
- <p><b><a name="declare-bundle!"></a><tt>declare-bundle!</tt></b> <tt><i>bundle-specifier
- association-list</i> -> undefined<br>
- </tt></p>
-
- <blockquote>
- Declares a new bundle named by the given bundle-specifier.
- The contents of the bundle are defined by the provided
- association list. The list contains associations
- between Scheme symbols and the message templates (Scheme
- strings) they name. If a bundle already exists with the
- given name, it is overwritten with the newly declared
- bundle.<br>
- </blockquote>
- <tt><a name="store-bundle"></a><b>store-bundle</b> <i>bundle-specifier</i> ->
- boolean</tt><br>
-
-
- <blockquote>
- Attempts to store a bundle named by the given bundle
- specifier, and previously made available using
- <tt>declare-bundle!</tt> or <tt>load-bundle!</tt>, in an
- unspecified mechanism that may be persistent across Scheme
- system restarts. If successful, a non-false value is
- returned. If unsuccessful, <tt>#f</tt> is returned.<br>
- </blockquote>
- <tt><a name="load-bundle!"></a><b>load-bundle!</b> <i>bundle-specifier</i> ->
- boolean</tt><br>
-
-
- <blockquote>
- Attempts to retrieve a bundle from an unspecified mechanism
- which stores bundles outside the Scheme system. If the
- bundle was retrieved successfully, the function returns a
- non-false value, and the bundle is immediately available to
- the Scheme system. If the bundle could not be found or loaded
- successfully, the function returns <tt>#f</tt>, and the
- Scheme system's bundle registry remains unaffected.<br>
- </blockquote>
- A compliant Scheme system may choose not to provide any
- external mechanism to store localized bundles. If it does
- not, it must still provide implementations for
- <tt>store-bundle</tt> and <tt>load-bundle!</tt>. In such a
- case, both functions must return <tt>#f</tt> regardless of the
- arguments given. Users of this SRFI should recognize that the
- inability to load or store a localized bundle in an external
- repository is <i>not</i> a fatal error.<br>
-
-
- <h3>Retrieving Localized Message Templates</h3>
-
- <p><a name="localized-template"></a><b><tt>localized-template</tt></b> <i><tt>package-name
- message-template-name</tt></i> <tt>-> <i>string or #f<br>
- </i></tt></p>
-
- <blockquote>
- Retrieves a localized message template for the given package
- name and the given message template name (both symbols).
- If no such message could be found, false (#f) is
- returned.<br>
- <br>
- </blockquote>
- After retrieving a template, the calling program can use
- <tt>format</tt> to produce a string that can be displayed to
- the user.<br>
-
-
- <h2>Examples</h2>
- The below example makes use of SRFI-29 to display simple,
- localized messages. It also defines its bundles in such a
- way that the Scheme system may store and retrieve the bundles
- from a more efficient system catalog, if available.<br>
-
-<pre>
-(let ((translations
- '(((en) . ((time . "Its ~a, ~a.")
- (goodbye . "Goodbye, ~a.")))
- ((fr) . ((time . "~1@*~a, c'est ~a.")
- (goodbye . "Au revoir, ~a."))))))
- (for-each (lambda (translation)
- (let ((bundle-name (cons 'hello-program (car translation))))
- (if (not (load-bundle! bundle-name))
- (begin
- (declare-bundle! bundle-name (cdr translation))
- (store-bundle! bundle-name)))))
- translations))
-
-(define localized-message
- (lambda (message-name . args)
- (apply format (cons (localized-template 'hello-program
- message-name)
- args))))
-
-(let ((myname "Fred"))
- (display (localized-message 'time "12:00" myname))
- (display #\newline)
-
- (display (localized-message 'goodbye myname))
- (display #\newline))
-
-;; Displays (English):
-;; Its 12:00, Fred.
-;; Goodbye, Fred.
-;;
-;; French:
-;; Fred, c'est 12:00.
-;; Au revoir, Fred.
-</pre>
-
- <H1>Implementation</H1>
-
- <p>The implementation requires that the Scheme system provide a
- definition for <tt>current-language</tt> and
- <tt>current-country</tt> capable of distinguishing the correct
- locale present during a Scheme session. The definitions of
- those functions in the reference implementation are not capable
- of that distinction. Their implementation is provided only so
- that the following code can run in any R4RS scheme system.
- <br>
- </p>
-
- <p>In addition, the below implementation of a compliant
- <tt>format</tt> requires SRFI-6 (Basic String Ports) and

-<H1>Abstract</H1>
-
-The <i>named-let</i> incarnation of the <code>let</code> form has two slight
-inconsistencies with the <code>define</code> form. As defined, the <code>let</code>
-form makes no accommodation for rest arguments, an issue of functionality
-and consistency. As defined, the <code>let</code> form does not accommodate
-signature-style syntax, an issue of aesthetics and consistency. Both
-issues are addressed here in a manner which is compatible with the traditional
-<code>let</code> form but for minor extensions.
-
-<H1>Rationale</H1>
-
-<H2>Signature-style Syntax</H2>
-
-Consider the following two equivalent definitions:
-
-<p><pre>
-(define fibonacci
- (lambda (n i f0 f1)
- (if (= i n)
- f0
- (fibonacci n (+ i 1) f1 (+ f0 f1)))))
-
-(define (fibonacci n i f0 f1)
- (if (= i n)
- f0
- (fibonacci n (+ i 1) f1 (+ f0 f1))))
-</pre>
-
-Although there is a named-let analog for the former form, there is none
-for the latter. To wit, suppose one wished to compute the 10th element
-of the Fibonacci sequence using a named let:
-
-<p>
-<pre>
-(let fibonacci ((n 10) (i 0) (f0 0) (f1 1))
- (if (= i n)
- f0
- (fibonacci n (+ i 1) f1 (+ f0 f1))))
-Values: 55
-</pre>
-
-As it stands, one cannot equivalently write
-
-<p>
-<pre>
-(let (fibonacci (n 10) (i 0) (f0 0) (f1 1))
- (if (= i n)
- f0
- (fibonacci n (+ i 1) f1 (+ f0 f1))))
-</pre>
-
-which is consistent with <code>define</code>'s signature-style form.
-<p>Those that favor the signature style may prefer this extension.
-In any case, it may be more appropriate to include all bound names within
-the binding section. As presented, this straightforward extension
-introduces no ambiguity or incompatibility with the existing definition
-of let.
-
-<H2>Rest Arguments</H2>
-
-As it stands, one cannot write a named let with rest arguments, as in
-
-<p>
-<pre>
-(let (blast (port (current-output-port)) . (x (+ 1 2) 4 5))
- (if (null? x)
- 'just-a-silly-contrived-example
- (begin
- (write (car x) port)
- (apply blast port (cdr x)))))
-</pre>
-
-otherwise equivalent to
-
-<p>
-<pre>
-(letrec ((blast (lambda (port . x)
- (if (null? x)
- 'just-a-silly-contrived-example
- (begin
- (write (car x) port)
- (apply blast port (cdr x)))))))
- (blast (current-output-port) (+ 1 2) 4 5))
-</pre>
-
-While this example is rather contrived, the functionality is not.
-There are several times when the author has used this construct in practice.
-Regardless, there is little reason to deny the <code>let</code> form access to
-all the features of lambda functionality.
-
-<H2>Symbols in Binding Sections</H2>
-
-Both the features above rely upon the placement of symbols in <code>let</code>
-binding lists (this statement is intentially simplistic). The only
-other apparent use of such symbol placement is to tersely bind variables
-to unspecified values. For example, one might desire to use
-<code>(let (foo bar baz) ...)</code>
-to bind <code>foo</code>, <code>bar</code>, and <code>baz</code> to
-unspecified values.
-
-<p>This usage is considered less important in light of the rationales
-presented above, and an alternate syntax is immediately apparent, as
-in <code>(let ((foo) (bar) (baz)) ...)</code> This may even
-be preferable, consistently parenthesizing normal binding clauses.
-
-<H1>Specification</H1>
-
-<H2>Syntax</H2>
-
-<p>
-A formal specification of the syntax follows. Below, body, expression,
-and identifier are free. Each instantiation of binding-name must be
-unique.
-</p>
-
-<p>
-<pre>
- let = "(" "let" let-bindings body ")"
- expressions = nothing | expression expressions
- let-bindings = let-name bindings
- | "(" let-name "." bindings ")"
- let-name = identifier
- bindings = "(" ")"
- | rest-binding
- | "(" normal-bindings ["." rest-binding] ")"
-normal-bindings = nothing
- | normal-binding normal-bindings
- normal-binding = "(" binding-name expression ")"
- binding-name = identifier
- rest-binding = "(" binding-name expressions ")"
-</pre>
-
-<p>
-For clarity and convenience, an informal specification follows.
-</p>
-
-<ol>
-<li><a name="unnamed">Unnamed</a>
-
-<p><pre>
-(let ((<parameter> <argument>)...)
- <body>...)
-</pre>
-</li>
-
-<li><a name="named-non-sig">
-Named, non-signature-style, no rest argument</a>
-
-<p><pre>
-(let <name> ((<parameter> <argument>)...)
- <body>...)
-</pre>
-</li>
-
-<li><a name="named-sig">Named, signature-style, no rest argument</a>
-
-<p><pre>
-(let (<name> (<parameter> <argument>)...)
- <body>...)
-</pre>
-</li>
-
-<li><a name="named-non-sig-rest">Named, non-signature-style, rest argument</a>
-
-<p><pre>
-(let <name> ((<parameter> <argument>)...
-
-. (<rest-parameter> <rest-argument>...))
- <body>...)
-</pre>
-
-<li><a name="named-sig-rest">Named, signature-style, rest argument</a>
-
-<p><pre>
-(let (<name> (<parameter> <argument>)...
-
-. (<rest-parameter> <rest-argument>...))
- <body>...)
-</pre>
-</li>
-</ol>
-
-<H2>Semantics</H2>
-
-Let <code>$lambda</code> and <code>$letrec</code> be hygienic bindings for the <code>lambda</code>
-and <code>letrec</code> forms, respectively.
-
-<ul>
-<li>For informal syntax 1:
-
-<p><pre>
-(($lambda (<parameter>...) <body>...) <argument>...)
-</pre>
-</li>
-
-<li>For informal syntaxes 2 and 3:
-
-<p>
-<pre>
-($letrec ((<name> ($lambda (<parameter>...) <body>...)))
- (<name> <argument>...))
-</pre>
-</li>
-
-<li>For informal syntaxes 4 and 5:
-
-<p>
-<pre>
-($letrec ((<name> ($lambda (<parameter>...
-
-. <rest-parameter>) <body>...)))
- (<name> <argument>... <rest-argument>...))
-</pre>
-</li>
-</ul>
-
-<H1>Implementation</H1>
-
-Here is an implementation using <code>SYNTAX-RULES</code>.
-
-<p>
-<pre>
-;; Use your own standard let.
-;; Or call a lambda.
-;; (define-syntax standard-let
-;;
-;; (syntax-rules ()
-;;
-;; ((let ((var val) ...) body ...)
-;; ((lambda (var ...) body ...) val ...))))
-
-(define-syntax let
-
- (syntax-rules ()
-
- ;; No bindings: use standard-let.
- ((let () body ...)
- (standard-let () body ...))
- ;; Or call a lambda.
- ;; ((lambda () body ...))
-
- ;; All standard bindings: use standard-let.
- ((let ((var val) ...) body ...)
- (standard-let ((var val) ...) body ...))
- ;; Or call a lambda.
- ;; ((lambda (var ...) body ...) val ...)
-
- ;; One standard binding: loop.
- ;; The all-standard-bindings clause didn't match,
- ;; so there must be a rest binding.
- ((let ((var val) . bindings) body ...)
- (let-loop #f bindings (var) (val) (body ...)))
-
- ;; Signature-style name: loop.
- ((let (name binding ...) body ...)
- (let-loop name (binding ...) () () (body ...)))
-
- ;; defun-style name: loop.
- ((let name bindings body ...)
- (let-loop name bindings () () (body ...)))))
-
-(define-syntax let-loop
-
- (syntax-rules ()
-
- ;; Standard binding: destructure and loop.
- ((let-loop name ((var0 val0) binding ...) (var ... ) (val ... ) body)
- (let-loop name ( binding ...) (var ... var0) (val ... val0) body))
-
- ;; Rest binding, no name: use standard-let, listing the rest values.
- ;; Because of let's first clause, there is no "no bindings, no name" clause.
- ((let-loop #f (rest-var rest-val ...) (var ...) (val ...) body)
- (standard-let ((var val) ... (rest-var (list rest-val ...))) . body))
- ;; Or call a lambda with a rest parameter on all values.
- ;; ((lambda (var ... . rest-var) . body) val ... rest-val ...))
- ;; Or use one of several other reasonable alternatives.
-
- ;; No bindings, name: call a letrec'ed lambda.
- ((let-loop name () (var ...) (val ...) body)
- ((letrec ((name (lambda (var ...) . body)))
- name)
- val ...))
-
- ;; Rest binding, name: call a letrec'ed lambda.
- ((let-loop name (rest-var rest-val ...) (var ...) (val ...) body)
- ((letrec ((name (lambda (var ... . rest-var) . body)))
- name)
- val ... rest-val ...))))
