oEdtk - A module for industrial printing processing
This module is the main of the toolkit oEdtk. It''s dedicated for documentation only. You will find here general informations for the diferents tools.

Scripts are developped in functional mode.
We try to use the Perl conventions, we are listenning all your recommandations
to make it better.
When a sub or a function comes from the user script it''s written like this :
&function_from_the_script();
Functions or 'methods' from perl modules are written like this :
recEdtk_motif ("016", "A67 A20 A*");
oEdtk::prodEdtk function This function open and share the mains filehandles IN and OUT. The parameter 'single_job_id' is optional. It''s used to send the job id to the the document builder application.
oEdtk::prodEdtk function This function close the mains filehandles IN and OUT. Filenames in parameters are used for information, but they are mandatory.
oEdtk::prodEdtk function
This function process the record line referenced in parameters as described
with 'recEdtk_' tools (see below). It''s made for fixed size records.
mandatory parameters
'offset_Key' is the starting point position of the record key
'key_Length' is the the length of the record key you are looking for
'Record_Line' is a reference to the record line you are working on
(prodEdtk_rec use the reference of the line)
optional parameters
'offset_of_Rec' is the starting point of the record from the beginning of
the line (if you want to cut down the begging of the line)
'Record_length' is the lenght of the record from the starting point of the record
prodEdtk_rec works by ordered key size, from the left to the right.
You should use it by working first with the biggest record to the smallest one.
Examples :
record 'abc' : abcvalue_1 value_2 value_3
record 'zzza' : zzza**value_1 value_2 value_3
record 'ywba' : ywba**value_AAAAAAAAA value_B
record '016' : ***016-value_A1 value_B2 value_C3
record '600' : ***600-value_A4 value_B5 value_C6
record definitions (in fact, the order is not important here) :
recEdtk_motif ("zzza","A4 A2 A8 A8 A7 A*");
recEdtk_motif ("ywba","A4 A2 A16 A7 A*");
recEdtk_motif ("abc", "A3 A8 A8 A7 A*");
recEdtk_motif ("016", "A3 A3 A1 A9 A9 A7 A*");
recEdtk_motif ("600", "A3 A1 A9 A9 A7 A*");
you will process from left to right, from bigest to smallest :
if (prodEdtk_rec(0, 4, $ligne)){
# this will process both records 'zzza' and 'ywba' .
} elsif (prodEdtk_rec(0, 3, $ligne, 3)){
# this will process records 'abc'
# (and cut away first 3 caracters of the record line).
} elsif (prodEdtk_rec(3, 3, $ligne, 6)){
# this will process both records '016' and '600'
# (and cut away first 6 caracters of the record line).
} else {
# if not, record is ignored
warn "INFO IGNORE REC. line $.\n";
}
prodEdtk_rec return '1' when it recognize and process the record (including
the output if recEdtk_output is defined). Values extracted from the record are
splitted in @DATATAB oEdtk global array.
prodEdtk_rec return '0' when it did not recognize the record.
prodEdtk_rec make these differents steps :
1 - look if there is a record key corresponding
2 - run the pre-process function if defined (see L<oEdtk::recEdtk_pre_process>)
3 - unpack the record according to recEdtk_motif definition into @DATATAB
4 - run the process function if defined (see L<oEdtk::recEdtk_process>)
5 - build output if recEdtk_output is defined
6 - run the post-process function if defined (see L<oEdtk::recEdtk_post_process>)
oEdtk::prodEdtk function
Create a record with the 'Record_Key_ID' identifier or type. This key
identifier should be in the record.
This function define the 'Record_Template' used to expand / extract the record
(see L<perlfunc::unpack> for template descritpion).
This function is mandatory, but could be defined after recEdtk_pre_process.
example :
recEdtk_motif ("016", "A2 A10 A15 A10 A15 A*");
it''s recommended to add 'A*' at the end of the template to cut away any
unexpected data that will remain at the end of the record.
oEdtk::prodEdtk function This function link the record 'Record_Key_ID' with a process sub. This sub is called after the extraction / expanding of the record. When this process is defined, it's called before the building of the output (if defined, see L<oEdtk::recEdtk_output> ). You can access the expanded data by reading/writing global tab @DATATAB. This function is optional.
oEdtk::prodEdtk function
This function define an 'Output_Template' for the record 'Record_Key_ID'. This
template is used to build the output file (see L<perlfunc::sprintf|/"sprintf"> for the
template description).
The output is build after the record process ( L<oEdtk::recEdtk_process> )
if this one is defined.
You can access the expanded data by reading/writing global tab @DATATAB.
This function is optional. If no recEdtk_output is defined for the
'Record_Key_ID', the record would be erased at the next record process.
Example :
recEdtk_output ("016", "<SK>%s<#DATE=%s><SK>%s");
oEdtk::prodEdtk function This function link the record 'Record_Key_ID' with a process sub. This sub is called after the building of the output. When this process is defined, it''s called before the next record read. You can access the expanded data by reading/writing global tab @DATATAB. This function is optional.
oEdtk::prodEdtk function This function will erase all the descriptions made for the record 'Record_Key_ID'. This is usefull when you want to ignore a record (this will cause a message 'Record Unknown' as if it has never been declared before) or when you want to redefine a record during the process.
oEdtk::prodEdtk function
This function will erase (as above) AND redefine the record 'Record_Key_ID' and
its template 'Record_Template'.
With this function, you define the necessary to syart processing the record.It''s
the less you can do.
example :
recEdtk_redefine ("016", "A2 A10 A15 A10 A15 A*");
