Re: [Bug-apl] How to create profile in preferences file?

[Juergen Sauermann]

Hi David,

thanks for analyzing this. I have split the option parsing in two parts:
parse_argv_1() before reading the preference files and parse_argv_2()
after reading them. Command line options are supposed to override settings in the
preference files therefore most options shall be considered after reading the preference
files. SVN 512.

Thank you, Jüergen.

It turns out that there is a problem with the implementation:

In main.cc::init_apl(), uprefs.parse_argv() is called after the calls to
uprefs.read_config_file(). As a result, read_config_file() never sees
the value set by the -p N command-line argument.

If I move the call to parse_argv() ahead of the calls to
read_config_file(), the Profile entries are recognized as per your
intent.

I didn't investigate the semantics of option processing. The -p N
parsing may need to be a special case in order for the command-line
options to override the preferences when parse_argv() is invoked from
its current position in the code. Perhaps it's sufficient to call
parse_argv() both before and after the calls to read_config_file().

Hi David,

the plan was this:

   <preferences in all profiles>
   ...

Profile 1

   <preferences in first profile>
    ...

Profile 2

   <preferences in second profile>
   ...

The profile number 0 stands for "all profiles"

Not sure if I ever tested this.

I'd like to create multiple profiles in the GNU APL preferences file and
and select one at runtime using the -p N command-line option. I
apologize if I've overlooked something in the documentation, but I can't
find an example of how this works.
