- [def] is used to define a variable (like before)
but if we assign a string such as [def var "string"] the string is evaluated to bool
in a different way: empty string is false, not empty string is true
- added [def?] statement - similar like [def] but define a variable only if such
a variable is not already defined
- added [let] statement - similar like [def] but with lazy evaluation (it is an alias to a function)
if it is called to assign a string e.g. [let var "string"] then this has the
same meaning like [def] - an alias is only created when we assign a function e.g. [let var my_function]
both [def] and [let] are using the same Vars object
- added [let?] - make an alias but only if such a variable is not already defined
- a std::map of variables moved outside of Generator
added method void SetVariables(Vars & variables);
- fixed: a result status was not correctly propagated when evaluating [def] statements,
this was in Call(...) function: last_res from variables was set in Find()
but later was overwritten by Call(...) called for parameters (recursively)
fixed: container was not correctly parsed (in template mode)

this will be mainly used in conjuction with [for ...] statements
[for my_function:xxx]
[for my_function]
[my_function_value]
[my_function_valu:xxx] (references the first loop)
[end]
[end]
added: to FunInfo<>: a reference to current item from a pattern (const Item & item)
similary on the stack is added a pointer to an item
by having this reference you can compare a function's name and its postfix
added methods:
Stack * FindLastFor(const std::wstring & name);
Stack * FindLastFor(const std::wstring & name, const std::wstring & postfix);
template<class FunUserObject> FunUserObject * FindUserObject(const std::wstring & function_name, Stack ** ezc_stack = 0);
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@1038 e52654a7-88a9-db11-a3e9-0013d4bc506e
the syntax has been changed, now [ezc ...] is used with [end] statement
added: OutStreams<StreamType> class with a pool with output streams,
the Generator::Generate() method can take it as its argument
(Generator API has been changed)
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@1014 e52654a7-88a9-db11-a3e9-0013d4bc506e
added: objects.h with a base class for the object
and Objects container (similar as Functions container)
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@1011 e52654a7-88a9-db11-a3e9-0013d4bc506e
now this [fun1 fun2 "something" fun3]
will call fun1 with three arguments: fun2, "something" and fun3
and this [fun1 [fun2 "something"] fun3]
will call fun1 with two arguments: [fun2 "something] and fun3
"something" is an argument for fun2 function
removed: statements: [if-one] [if-any] [if-no] [if-any-no] [if-one-no]
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@1004 e52654a7-88a9-db11-a3e9-0013d4bc506e
we can provide a user definied function which does the same
added: to FunInfo<>:
Stack * stack_tab
size_t stack_index
a stack table and an index to the current stack item
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@988 e52654a7-88a9-db11-a3e9-0013d4bc506e
changed: a user definied function now is able to get a string and a boolean value (parameters)
changed: we do not longer support aliases for variables
a variable is only a string and a boolean value now
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@981 e52654a7-88a9-db11-a3e9-0013d4bc506e
(copied from cache.h)
fixed: in Generator: memory leak from block_stack
objects pointing by block_stack_tab[].out_stream
were not deleted
fixed: in Item: ClearCache() didn't clear all pointers
Function::parameters table were not used
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@979 e52654a7-88a9-db11-a3e9-0013d4bc506e
(now we have a tree in Item::Function.parameters too
and we should go through that tree as well)
fixed: in Generator: Item::Function.par should be cleared
only if Item::Function.name is not empty
changed: in Generator: use method 'write' of an output stream
instead of operator<<
added: Clear() method to Blocks class
changed: in Generator
Generator has its own Vars class now
we don't need SetVars() method
added: to Generator:
void CanUseCache(bool can_use_cache);
// set whether or not we can use cache for functions or blocks
// true by default
void CanUseVars(bool can_use_variables);
// set whether or not we can use variables: [def ...] statement
// true by default
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@977 e52654a7-88a9-db11-a3e9-0013d4bc506e
added: caching functions and blocks
caching is added into Pattern and Blocks
methods: CacheFunctions() and CacheBlocks()
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@975 e52654a7-88a9-db11-a3e9-0013d4bc506e
fixed: removed GetStringFromStream() method
it returns a reference to a local object (from stream.str())
now the code is used directly

changed: in Functions
Functions are only for user-defined functions now
(before they could remember a string variable too)
added: class Vars for variables
a variable can be a string or an alias to an other function or block
added: now we can have nested functions calls e.g.:
[function1 [function2]]
in the above example an output (stream) from function2 will be passed
as the first argument to funcion1 (will be passed as a string)
removed: UTF8() method from PatternParser
now it is treated that when we have only std::string (or char*)
that this is an UTF-8 string
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@970 e52654a7-88a9-db11-a3e9-0013d4bc506e
in Pattern we have only the tree
in PatternParser there is the whole logic used to parse a file
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@969 e52654a7-88a9-db11-a3e9-0013d4bc506e
Generate() methods can take std::vector with pointers to streams
added: 'ezc' keyword -- currently only for selecting streams
e.g.
[ezc stream "0" "3"] - after now the output is generated to streams 0 and 3
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@445 e52654a7-88a9-db11-a3e9-0013d4bc506e
[if-index] statement has to look for a last [for] statement on the stack
(because the stack is for all items now)
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@394 e52654a7-88a9-db11-a3e9-0013d4bc506e
now we have a stack item for all statements [if...] [normal_fun] etc.
previously was only for [for ...] statements
changed: FunInfo<> has a pointer to the current stack item
changed: now we have a static number of stack items (default: 300)
so you can remember a pointer to a stack item and this pointer
is always valid
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@393 e52654a7-88a9-db11-a3e9-0013d4bc506e
bool remove_fun_data
fun_data is removed only when remove_fun_data is true (default)
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@392 e52654a7-88a9-db11-a3e9-0013d4bc506e
now we have a pointer to FunData struct
by default the pointer is null
you can create an object of a class derived from FunData
an set the pointer to the object
those pointers will be kept on the [for] stack
and will be auto removed
(not finished yet -- need some testing)
added: to FunInfo<>::
bool is_if;
bool is_is;
bool is_normal;
bool is_filter;
removed: from FunInfo<>:
bool is_for_first_iter;
changed: in FunInfo<>:
int iter -> size_t iter
now it indicates the number of a current iteration for the [for] statement
for other statements than [for] this is always zero
(the same old behaviour as before revision 331)
added: in FunInfo<>:
size_t last_iter
it indicates the number of a previous [for] iteration
for a [for] it returns not the current iterator but a value from a previous [for]
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@391 e52654a7-88a9-db11-a3e9-0013d4bc506e
// indicates that this function is from [for ...] statement
bool is_for;
// indicates that this function is from [for ...] statement
// and this is a first iteration (iter=0 too)
// this is only for convenience -- you don't have to check is_for and iter==0
bool is_for_first_iter;
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@380 e52654a7-88a9-db11-a3e9-0013d4bc506e
previously they used FunInfo::res, now they use FunInfo::out
and the out string is not put to the main output stream
added: FunInfo<>::case_sensitive (default true)
when false then [is] statement is comparing in case insensitive manner
changed: the out stream in [if...] [for] statements
the output text is ingored now
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@344 e52654a7-88a9-db11-a3e9-0013d4bc506e
a new statement [filter]
syntax:
[filter funcion_name]....[end]
everything which is between [filter] and [end] is processed normally and
at the end it is passed to the function (function_name)
FunInfo struct has 'in' input stream now
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@333 e52654a7-88a9-db11-a3e9-0013d4bc506e
sample:
[for my_function]
[for my_function]
foo
[end]
[end]
changed: FunInfo::iter has a value from the last [for] statement now
sample:
[for my_function]
[other_function]
[end]
void other_function(Info &i)
{
// here i.iter is the number of iteration
// previously was always zero
}
changed: small optimization in [for]
the proper function is being looking for only once at the beginning
previously it was searched in each iteration
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@331 e52654a7-88a9-db11-a3e9-0013d4bc506e
you can cache all functions (their addresses) in the pattern
changed: now we have two methods for generating content:
Generator<>::Generate(StreamType & o, Pattern & p, Functions<StreamType> & f);
similar like previous -- Set(...) methods were removed as well as the second ctor
and a second one:
Generate(StreamType & o, Pattern & p);
without functions, the functions should be cached beforehand in the pattern
by calling CacheFunctions() method on the pattern
this gives O(1) complexity when looking for a specific function
previously was O(log n)
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@329 e52654a7-88a9-db11-a3e9-0013d4bc506e
StreamType
we use method write where the content should not be escaped (html escaping)
we use operator<< where the content can be escaped (such as error messages)
PrintSpecialText() and PrintNormalText() are a little faster now
we use 'write' for a whole text instead of printing each character
git-svn-id: svn://ttmath.org/publicrep/ezc/trunk@328 e52654a7-88a9-db11-a3e9-0013d4bc506e
they can be even used without the rest library
as only a library for converting between wide characters and UTF-8
changed: everywhere we use std::wstring instead of std::string
changed: Generator and Functions are templates now
they take a stream type
renamed: Info to FunInfo and it is a template too
taking a stream type
now you can use other kind of streams with the library
previous was only std::ostringstream
