[bp-dev] LoadSettings()

[Bernard B. <ber...@gm...>]

Dear Anthony,

To implement the -se.some_settings_file option you will need a few more 
changes in the LoadSettings() procedure. It should ignore output options 
which are now set in the command line.

Variables that will remain significant in the ‘-se’ file are the ones 
that need to be stored and retrieved each time the application is 
prompted to produce items. Other variables may be temporarily stored on 
the interface, but starting the interface will each time set them to 
default values.

For instance, the current Grammar page takes care of the output option:

• No file (i.e. real-time MIDI)
• BP data file
• MIDI file
• CSOUND file

and it appends the corresponding option after the command.

LoadSettings() is in SaveLoads1.c.

Below are the names of variables along with their meanings and default 
values when necessary. Fot instance, you will replace 
"ReadInteger(refnum,&OutMIDI,&pos)" with 
"ReadInteger(refnum,&dummy_integer,&pos)" and keep the old line in a 
comment just in case…

• Use MIDI in/out = OutMIDI
• Write MIDI files = WriteMIDIfile
• Write Csound scores = OutCsound
• Csound file format = CsoundFileFormat = 2
    (Probably obsolete: choosing between MacOS, Windows and Unix. Should 
be set to Unix, value is ‘2’.)
• Opcode OMS = *p_oms = 0
• Show messages = ShowMessages
• File save mode = FileSaveMode
   (Read below)
• File write mode = FileWriteMode = 0
   (This means that the items is immediately written to the file instead 
of being first played on MIDI.)

A few more instructions need to be commented out, for instance :

// if(oldoutcsound && !OutCsound && !startup) CloseCsScore();
// if(oldwritemidifile && !WriteMIDIfile && !startup) CloseMIDIFile();
// if(OutMIDI && !oldoutmidi && !InitOn && !startup) ResetMIDI(FALSE);

I am wondering about "File save mode" used to save MIDI and Csound 
files. We had the following options:

0 = Prompt for changing filename
1 = Save each item to a new file
2 = Store all items to same file

Mode 1 is probably the only valid one. If we need mode 2 then an 
additional option needs to be added, telling that the file should not be 
overwritten, it shoud be completed with the produced item(s).

BP2.9.8 used to load ‘-se.startup’ when starting up. This may remain 
necessary in case the grammar or data file does not indicate a specific 
‘-se’ file. I am enclosing a display of ‘-se.startup’ on the PHP 
interface. MIDI input and output filters will be considered later…

In other cases the interface picks up the name of the ‘-se’ file and 
appends it as an option of the command. Note that no variable in the 
settings file has an impact on compiling grammar and alphabet. Compiling 
and producing are 2 separate operations.

All these changes maybe revised if necessary. I am keeping the 
definitions and values of obsolete ones on the interface, ready to be 
reinstalled if needed.
