astlog not working in MacOS environments

[gzrubio]

Hello!

First of all thanks for your amazing tool, it has made my life way easier :)

I recently switched to a MacOS environment and when I try to use the tool I get an error about a file missing:

(astlog) gonzalo@XXXX ~ % astlog $PWD/sip.log
Traceback (most recent call last):

    with open('/proc/meminfo') as f:
FileNotFoundError: [Errno 2] No such file or directory: '/proc/meminfo'

I suspect this has to do with the get_memory_size method:

Given that MacOS does not use /proc/ :

• is there any way to circumvent this memory size check?
• Alternatively, can we add support for it? -> Do you accept external PRs? I would not mind to try to fix it myself!

Best,

I ran into this issue also. You can replace get_memory_size() in reader.py with this, and you'll be in good shape:

def get_memory_size():
    try:
        # Run the sysctl command to get memory information
        sysctl_output = subprocess.check_output(['sysctl', 'hw.memsize']).decode('utf-8')
        
        # Extract the memory size from the output
        m = re.search(r'hw\.memsize:\s+(\d+)', sysctl_output)
        if m:
            mem_total_bytes = int(m.groups()[0])
            return mem_total_bytes
    except Exception as e:
        print(f"Error retrieving memory size: {e}")
        return None
