'''Sequence insertion
A sequence may be inserted using an 'in' command. The 'in'
command specifies the name of a sequence object and text to
be inserted for each element in the sequence.
The EPFS syntax for the in command is::
%(in name)[
text
%(in name)]
The HTML syntax for the in command is::
<!--#in name-->
text
<!--#/in name-->
See the example below that shows how 'if', 'else', and 'in' commands
may be combined to display a possibly empty list of objects.
The text included within an 'in' command will be refered to
as an 'in' block.
Synopsis
If the variable 'sequence' exists as a sequence, a simple case
of the 'in' tag is used as follows::
<!--#in sequence-->some markup<!--#/in-->
A more complete case is used as follows::
<!--#in sequence sort=age-->
<!--#var sequence-number-->) <!--#var age-->
<!--#/in-->
Attributes
sort -- Define the sort order for sequence items. Parameter to the
attribute is either a sort option, or list of sort options separated
by comma. Every sort option consists of variable name, optional
comparison function name (default is cmp) and optional sort order
(default is asc).
Examples: sort="date" or sort="date,time" or
sort="title/locale,date/cmp/desc". If you want to specify sort order,
you cannot omit the function; use cmp for standard comparison.
Few predefined comparison functions available: standard cmp,
nocase (ignore string case), strcoll (alias "locale"),
strcoll_nocase (alias "locale_nocase"). Locale functions are
available only if module locale is already imported (you started Zope
with -L locale).
sort_expr -- The "sort" attribute accepts only static list of
sort options. This calculated parameter allows you to calculate the
list of sort options on the fly.
sort_expr -- This allows an expression to control sort order.
reverse -- Reverse the sequence (may be combined with sort). Note
that this can cause a huge memory use in lazy activation instances.
reverse_expr -- This calculated parameter allows you to calculate the
need of reversing on the fly.
Within an 'in' block, variables are substituted from the
elements of the iteration unless the 'no_push_item' optional
is specified. The elements may be either instance or mapping
objects. In addition, the variables:
'sequence-item' -- The element.
'sequence-var-nnn' -- The value of a specific named attribute
of the item, where 'nnn' is the name. For example, to get
an items 'title' attribute, use 'sequence-var-title'. This
construct is most useful in an 'if' tag to test whether an
attribute is present, because the attribute lookup will be
extended to the full document template namespace.
'sequence-key' -- The key associated with the element in an
items list. See below.
'sequence-index' -- The index, starting from 0, of the
element within the sequence.
'sequence-number' -- The index, starting from 1, of the
element within the sequence.
'sequence-letter' -- The index, starting from 'a', of the
element within the sequence.
'sequence-Letter' -- The index, starting from 'A', of the
element within the sequence.
'sequence-roman' -- The index, starting from 'i', of the
element within the sequence.
'sequence-Roman' -- The index, starting from 'I', of the
element within the sequence.
'sequence-start' -- A variable that is true if the element
being displayed is the first of the displayed elements,
and false otherwise.
'sequence-end' -- A variable that is true if the element
being displayed is the last of the displayed elements,
and false otherwise.
are defined for each element.
Normally, 'in' blocks are used to iterate over sequences of
instances. If the optional parameter 'mapping' is specified
after the sequence name, then the elements of the sequence
will be treated as mapping objects.
An 'in' command may be used to iterate over a sequence of
dictionary items. If the elements of the iteration are
two-element tuples, then then the template code given in the
'in' block will be applied to the second element of each
tuple and may use a variable, 'sequence-key' to access the
first element in each tuple.
Batch sequence insertion
When displaying a large number of objects, it is sometimes
desirable to display just a sub-sequence of the data.
An 'in' command may have optional parameters,
as in::
<!--#in values start=start_var size=7-->
The parameter values may be either integer literals or
variable names.
Up to five parameters may be set:
'start' -- The number of the first element to be shown,
where elements are numbered from 1.
'end' -- The number of the last element to be shown,
where elements are numbered from 1.
'size' -- The desired number of elements to be shown at
once.
'orphan' -- The desired minimum number of objects to be
displayed. The default value for this
parameter is 0.
'overlap' -- The desired overlap between batches. The
default is no overlap.
Typically, only 'start' and 'size' will be specified.
When batch insertion is used, several additional variables are
defined for use within the sequence insertion text:
'sequence-query' -- The original query string given in a get
request with the form variable named in the 'start'
attribute removed. This is extremely useful when
building URLs to fetch another batch.
To see how this is used, consider the following example::
<!--#in search_results size=20 start=batch_start-->
... display rows
<!--#if sequence-end--> <!--#if next-sequence-->
<a href="&dtml-URL;/&dtml-sequence-query;batch_start=&dtml-next-sequence-start-number;">
(Next &dtml-next-sequence-size; results)
</a>
<!--#/if--> <!--#/if-->
<!--#/in-->
If the original URL is: 'foo/bar?x=1&y=2', then the
rendered text (after row data are displayed) will be::
<a href="foo/bar?x=1&amp;y=2&amp;batch_start=20">
(Next 20 results)
</a>
If the original URL is: 'foo/bar?batch_start=10&x=1&y=2',
then the rendered text (after row data are displayed)
will be::
<a href="foo/bar?x=1&amp;y=2&amp;batch_start=30">
(Next 20 results)
</a>
'sequence-step-start-index' -- The index, starting from 0,
of the start of the current batch.
'sequence-step-end-index' -- The index, starting from 0, of
the end of the current batch.
'sequence-step-size' -- The batch size used.
'previous-sequence' -- This variable will be true when the
first element is displayed and when the first element
displayed is not the first element in the sequence.
'previous-sequence-start-index' -- The index, starting from
0, of the start of the batch previous to the current
batch.
'previous-sequence-end-index' -- The index, starting from
0, of the end of the batch previous to the current
batch.
'previous-sequence-size' -- The size of the batch previous to
the current batch.
'previous-batches' -- A sequence of mapping objects
containing information about all of the batches prior
to the batch being displayed.
Each of these mapping objects include the following
variables:
batch-start-index -- The index, starting from
0, of the beginning of the batch.
batch-end-index -- The index, starting from
0, of the end of the batch.
batch-size -- The size of the batch.
'next-sequence' -- This variable will be true when the last
element is displayed and when the last element
displayed is not the last element in the sequence.
'next-sequence-start-index' -- The index, starting from
0, of the start of the batch after the current
batch.
'next-sequence-end-index' -- The index, starting from
0, of the end of the batch after the current
batch.
'next-sequence-size' -- The size of the batch after
the current batch.
'next-batches' -- A sequence of mapping objects
containing information about all of the batches after
the batch being displayed.
Each of these mapping objects include the following
variables:
batch-start-index -- The index, starting from
0, of the beginning of the batch.
batch-end-index -- The index, starting from
0, of the end of the batch.
batch-size -- The size of the batch.
For each of the variables listed above with names ending in
"-index", there are variables with names ending in "-number",
"-roman", "-Roman", "-letter", and "-Letter" that are indexed
from 1, "i", "I", "a", and "A", respectively. In addition,
for every one of these variables there are variables with
names ending in "-var-xxx", where "xxx" is an element
attribute name or key.
Summary statistics
When performing sequence insertion, special variables may be
used to obtain summary statistics. To obtain a summary
statistic for a variable, use the variable name:
'statistic-name', where 'statistic' is a statistic name and
'name' is the name of a data variable.
Currently supported statistic names are:
total -- The total of numeric values.
count -- The total number of non-missing values.
min -- The minimum of non-missing values.
max -- The maximum of non-missing values.
median -- The median of non-missing values.
mean -- The mean of numeric values values.
variance -- The variance of numeric values computed with a
degrees of freedom equal to the count - 1.
variance-n -- The variance of numeric values computed with a
degrees of freedom equal to the count.
standard-deviation -- The standard deviation of numeric values
computed with a degrees of freedom equal to the count - 1.
standard-deviation-n -- The standard deviation of numeric
values computed with a degrees of freedom equal to the count.
Missing values are either 'None' or the attribute 'Value'
of the module 'Missing', if present.
'else' continuation tag within in
An 'else' tag may be used as a continuation tag in the 'in' tag.
The source after the 'else' tag is inserted if:
- The sequence given to the 'in' tag is of zero length, or
- The 'previous' attribute was used and their are no
previous batches, or
- The 'next' attribute was used and their are no
next batches, or

''' The Let tag was contributed to Zope by and is copyright, 1999
Phillip J. Eby. Permission has been granted to release the Let tag
under the Zope Public License.
Let name=value...
The 'let' tag is used to bind variables to values within a block.
The text enclosed in the let tag is rendered using information
from the given variables or expressions.
For example::
<!--#let foofunc="foo()" my_bar=bar-->
foo() = <!--#var foofunc-->,
bar = <!--#var my_bar-->
<!--#/let-->
Notice that both 'name' and 'expr' style attributes may be used to
specify data. 'name' style attributes (e.g. my_bar=bar) will be
rendered as they are for var/with/in/etc. Quoted attributes will
be treated as Python expressions.
Variables are processed in sequence, so later assignments can
reference and/or overwrite the results of previous assignments,
as desired.

usage:

<!--#except-->
<!--#else-->
<!--#/try-->
or:
<!--#try-->
<!--#finally-->
<!--#/try-->
The DTML try tag functions quite like Python's try command.
The contents of the try tag are rendered. If an exception is raised,
then control switches to the except blocks. The first except block to
match the type of the error raised is rendered. If an except block has
no name then it matches all raised errors.
The try tag understands class-based exceptions, as well as string-based
exceptions. Note: the 'raise' tag raises string-based exceptions.
Inside the except blocks information about the error is available via
three variables.
'error_type' -- This variable is the name of the exception caught.
'error_value' -- This is the caught exception's value.
'error_tb' -- This is a traceback for the caught exception.
The optional else block is rendered when no exception occurs in the
try block. Exceptions in the else block are not handled by the preceding
except blocks.
The try..finally form specifies a `cleanup` block, to be rendered even
when an exception occurs. Note that any rendered result is discarded if
an exception occurs in either the try or finally blocks. The finally block
is only of any use if you need to clean up something that will not be
cleaned up by the transaction abort code.
The finally block will always be called, wether there was an exception in
the try block or not, or wether or not you used a return tag in the try
block. Note that any output of the finally block is discarded if you use a
return tag in the try block.
If an exception occurs in the try block, and an exception occurs in the
finally block, or you use the return tag in that block, any information
about that first exception is lost. No information about the first
exception is available in the finally block. Also, if you use a return tag
in the try block, and an exception occurs in the finally block or you use
a return tag there as well, the result returned in the try block will be
lost.

Python expression support
Several document template tags, including 'var', 'in', 'if', 'else',
and 'elif' provide support for using Python expressions via an
'expr' tag attribute.
Expressions may be used where a simple variable value is
inadequate. For example, an expression might be used to test
whether a variable is greater than some amount::
<!--#if expr="age > 18"-->
or to transform some basic data::
<!--#var expr="phone[:3]"-->
Objects available in the document templates namespace may be used.
Subobjects of these objects may be used as well, although subobject
access is restricted by the optional validation method.
In addition, a special additional name, '_', is available. The '_'
variable provides access to the document template namespace as a
mapping object. This variable can be useful for accessing objects
in a document template namespace that have names that are not legal
Python variable names::
<!--#var expr="_['sequence-number']*5"-->
This variable also has attributes that provide access to standard
utility objects. These attributes include:
- The objects: 'None', 'abs', 'chr', 'divmod', 'float', 'hash',
'hex', 'int', 'len', 'max', 'min', 'oct', 'ord', 'pow',
'round', and 'str' from the standard Python builtin module.
- Special security-aware versions of 'getattr' and 'hasattr',
- The Python 'string', 'math', and 'random' modules, and
- A special function, 'test', that supports if-then expressions.
The 'test' function accepts any number of arguments. If the
first argument is true, then the second argument is returned,
otherwise if the third argument is true, then the fourth
argument is returned, and so on. If there is an odd number of
arguments, then the last argument is returned in the case that
none of the tested arguments is true, otherwise None is
returned.
For example, to convert a value to lower case::
<!--#var expr="_.string.lower(title)"-->

"""Variable insertion parameters
When inserting variables, parameters may be specified to
control how the data will be formatted. In HTML source, the
'fmt' parameter is used to specify a C-style or custom format
to be used when inserting an object. In EPFS source, the 'fmt'
parameter is only used for custom formats, a C-style format is
specified after the closing parenthesis.
Custom formats
A custom format is used when outputing user-defined
objects. The value of a custom format is a method name to
be invoked on the object being inserted. The method should
return an object that, when converted to a string, yields
the desired text. For example, the DTML code::
<dtml-var date fmt=DayOfWeek>
Inserts the result of calling the method 'DayOfWeek' of the
object bound to the variable 'date', with no arguments.
In addition to object methods, serveral additional custom
formats are available:
'whole-dollars' -- Show a numeric value with a dollar symbol.
'dollars-and-cents' -- Show a numeric value with a dollar
symbol and two decimal places.
'collection-length' -- Get the length of a collection of objects.
Note that when using the EPFS source format, both a
C-style and a custom format may be provided. In this case,
the C-Style format is applied to the result of calling
the custom formatting method.
Null values and missing variables
In some applications, and especially in database applications,
data variables may alternate between "good" and "null" or
"missing" values. A format that is used for good values may be
inappropriate for null values. For this reason, the 'null'
parameter can be used to specify text to be used for null
values. Null values are defined as values that:
- Cannot be formatted with the specified format, and
- Are either the special Python value 'None' or
are false and yield an empty string when converted to
a string.
For example, when showing a monitary value retrieved from a
database that is either a number or a missing value, the
following variable insertion might be used::
<dtml-var cost fmt="$%.2d" null=\'n/a\'>
Missing values are providing for variables which are not
present in the name space, rather than raising an NameError,
you could do this:
<dtml-var cost missing=0>
and in this case, if cost was missing, it would be set to 0.
In the case where you want to deal with both at the same time,
you can use 'default':
<dtml-var description default=''>
In this case, it would use '' if the value was null or if the
variable was missing.
String manipulation
A number of special attributes are provided to transform the
value after formatting has been applied. These parameters
are supplied without arguments.
'lower' -- cause all upper-case letters to be converted to lower case.
'upper' -- cause all upper-case letters to be converted to lower case.
'capitalize' -- cause the first character of the inserted value
to be converted to upper case.
'spacify' -- cause underscores in the inserted value to be
converted to spaces.
'thousands_commas' -- cause commas to be inserted every three
digits to the left of a decimal point in values containing
numbers. For example, the value, "12000 widgets" becomes
"12,000 widgets".
'html_quote' -- convert characters that have special meaning
in HTML to HTML character entities.
'url_quote' -- convert characters that have special meaning
in URLS to HTML character entities using decimal values.
'url_quote_plus' -- like url_quote but also replace blank
space characters with '+'. This is needed for building
query strings in some cases.
'url_unquote' -- convert HTML character entities in strings
back to their real values.
'url_unquote_plus' -- like url_unquote, but also
replace '+' characters with spaces.
'sql_quote' -- Convert single quotes to pairs of single
quotes. This is needed to safely include values in
Standard Query Language (SQL) strings.
'newline_to_br' -- Convert newlines and carriage-return and
newline combinations to break tags.
'url' -- Get the absolute URL of the object by calling it\'s
'absolute_url' method, if it has one.
Truncation
The attributes 'size' and 'etc' can be used to truncate long
strings. If the 'size' attribute is specified, the string to
be inserted is truncated at the given length. If a space
occurs in the second half of the truncated string, then the
string is further truncated to the right-most space. After
truncation, the value given for the 'etc' attribute is added to
the string. If the 'etc' attribute is not provided, then '...'
is used. For example, if the value of spam is
'"blah blah blah blah"', then the tag
'<dtml-var spam size=10>' inserts '"blah blah ..."'.
Evaluating expressions without rendering results
A 'call' tag is provided for evaluating named objects or expressions
without rendering the result.

'''Nested namespace access
The 'with' tag is used to introduce nested namespaces.
The text enclosed in the with tag is rendered using information
from the given variable or expression.
For example, if the variable 'person' is bound to an object that
has attributes 'name' and 'age', then a 'with' tag like the
following can be used to access these attributes::
<!--#with person-->
<!--#var name-->,
<!--#var age-->
<!--#/with-->
Eather a 'name' or an 'expr' attribute may be used to specify data.
A 'mapping' attribute may be used to indicate that the given data
should be treated as mapping object, rather than as an object with
named attributes.

The let tag:
is a new tag that lets you create blocks like:
<!--#in "1,2,3,4"-->
<!--#let num=sequence-item
index=sequence-index
result="num*index"-->
<!--#var num--> * <!--#var index--> = <!--#var result-->
<!--#/let-->
<!--#/in-->
Which yields:
1 * 0 = 0
2 * 1 = 2
3 * 2 = 6
4 * 3 = 12
The #let tag works like the #with tag, but is more flexible in that
it allows you to make multiple assignments, and allows you to chain
assignments, using earlier declarations in later assignments. Notice
inthe ablove example, the 'result' variable is based on 'num' and
'index', both of which are assigned in the same #let expression.
Syntacticly, each argument to be evalulated in the head of the let
tag must be seperated by a newline. Enclosing an argument in double
quotes causes it to be evaluated by the DTML expression machinery.
Un-quoted arguments are referenced by name.
Evaluation is in sequence with the result of earlier assignments
available to later ones. Later assignments can also override earlier
ones, which can be helpful for longer step-by-step calculations. The
variables thus set are in effect for the life of the <!--#let-->
block.

'''Document templates with fill-in fields
Document templates provide for creation of textual documents, such as
HTML pages, from template source by inserting data from python objects
and name-spaces.
When a document template is created, a collection of default values to
be inserted may be specified with a mapping object and with keyword
arguments.
A document templated may be called to create a document with values
inserted. When called, an instance, a mapping object, and keyword
arguments may be specified to provide values to be inserted. If an
instance is provided, the document template will try to look up values
in the instance using getattr, so inheritence of values is supported.
If an inserted value is a function, method, or class, then an attempt
will be made to call the object to obtain values. This allows
instance methods to be included in documents.
Document templates masquerade as functions, so the python object
publisher (Bobo) will call templates that are stored as instances of
published objects. Bobo will pass the object the template was found in
and the HTTP request object.
Two source formats are supported:
Extended Python format strings (EPFS) --
This format is based on the insertion by name format strings
of python with additional format characters, '[' and ']' to
indicate block boundaries. In addition, parameters may be
used within formats to control how insertion is done.
For example:
%%(date fmt=DayOfWeek upper)s
causes the contents of variable 'date' to be inserted using
custom format 'DayOfWeek' and with all lower case letters
converted to upper case.
HTML --
This format uses HTML server-side-include syntax with
commands for inserting text. Parameters may be included to
customize the operation of a command.
For example:
<!--#var total fmt=12.2f-->
is used to insert the variable 'total' with the C format
'12.2f'.
Document templates support conditional and sequence insertion
Document templates extend python string substitition rules with a
mechanism that allows conditional insertion of template text and that
allows sequences to be inserted with element-wise insertion of
template text.
Access Control
Document templates provide a basic level of access control by
preventing access to names beginning with an underscore.
Additional control may be provided by providing document templates
with a 'guarded_getattr' and 'guarded_getitem' method. This would
typically be done by subclassing one or more of the DocumentTemplate
classes.
If provided, the the 'guarded_getattr' method will be called when
objects are accessed as instance attributes or when they are
accessed through keyed access in an expression.
Document Templates may be created 4 ways:
DocumentTemplate.String -- Creates a document templated from a
string using an extended form of python string formatting.
DocumentTemplate.File -- Creates a document templated bound to a
named file using an extended form of python string formatting.
If the object is pickled, the file name, rather than the file
contents is pickled. When the object is unpickled, then the
file will be re-read to obtain the string. Note that the file
will not be read until the document template is used the first
time.
DocumentTemplate.HTML -- Creates a document templated from a
string using HTML server-side-include rather than
python-format-string syntax.
DocumentTemplate.HTMLFile -- Creates an HTML document template
from a named file.
