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 :
oe_rec_motif("016", "A67 A20 A*");
oe_new_job( input_file, output_file, [single_job_id] )
This function opens and shares the main filehandles IN and OUT. The parameter 'single_job_id' is optional. It is used to send the job id to the document builder application.
oe_compo_link( input_file, output_file )
This function closes the main filehandles IN and OUT. Filenames in parameters are used for information, but they are mandatory.
oe_process_ref_rec( offset_Key, key_Length, Record_Line, [offset_of_Rec, Record_length] )
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 (oe_process_ref_rec uses the reference of the line)
oe_process_ref_rec
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
The oe_process_ref_rec function 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) : oe_rec_motif ("zzza","A4 A2 A8 A8 A7 A*"); oe_rec_motif ("ywba","A4 A2 A16 A7 A*"); oe_rec_motif ("abc", "A3 A8 A8 A7 A*"); oe_rec_motif ("016", "A3 A3 A1 A9 A9 A7 A*"); oe_rec_motif ("600", "A3 A1 A9 A9 A7 A*"); you will process from left to right, from bigest to smallest : if (oe_process_ref_rec(0, 4, $ligne)) { # this will process both records 'zzza' and 'ywba' . } elsif (oe_process_ref_rec(0, 3, $ligne, 3)) { # this will process records 'abc' # (and cut away first 3 caracters of the record line). } elsif (oe_process_ref_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"; }
The oe_process_ref_rec function returns 1 when it recognizes and processes the record (including the output if oe_rec_output is defined). Values extracted from the record are split into the @DATATAB oEdtk global array. oe_process_ref_rec returns 0 when it could not recognize the record.
oe_rec_output
@DATATAB
The oe_process_ref_rec function makes these differents steps :
look if there is a record key corresponding
run the pre-process function if defined (see "oe_rec_pre_process")
unpack the record according to oe_rec_motif definition into @DATATAB
run the process function if defined (see "oe_rec_process")
build output if oe_rec_output is defined
run the post-process function if defined (see "recEdtk_post_process")
oe_rec_motif( Record_Key_ID, Record_Template )
Create a record with the 'Record_Key_ID' identifier or type. This key identifier should be in the record. This function defines the 'Record_Template' used to expand / extract the record (see unpack for template description). This function is mandatory, but cannot be defined after oe_rec_pre_process.
oe_rec_pre_process
Example :
oe_rec_motif("016", "A2 A10 A15 A10 A15 A*");
It is 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.
oe_rec_process( Record_Key_ID, \&user_sub_reference )
This function links 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 "oe_rec_output"). You can access the expanded data by reading/writing global tab @DATATAB. This function is optional.
oe_rec_output( Record_Key_ID, Output_Template )
This function defines an 'Output_Template' for the record 'Record_Key_ID'. This template is used to build the output file (see sprintf for the template description). The output is built after the record process ("oe_rec_process" if this one is defined). You can access the expanded data by reading/writing global tab @DATATAB. This function is optional. If no oe_rec_output is defined for the 'Record_Key_ID', the record would be erased at the next record process.
oe_rec_output("016", "<SK>%s<#DATE=%s><SK>%s");
recEdtk_post_process( Record_Key_ID, \&user_sub_reference )
This function links 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.
recEdtk_erase( Record_Key_ID )
This function will erase all the descriptions made for the record 'Record_Key_ID'. This is useful 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.
recEdtk_redefine( Record_Key_ID, Record_Template )
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 start processing the record. It's the less you can do.
recEdtk_redefine("016", "A2 A10 A15 A10 A15 A*");
