OSError: [Errno 36] File name too long: '/home/user/.local/share/rofimoji/recent/…'

[c4rlo]

I have this in my .config/rofimoji.rc:

files = [arrows, emojis, general_punctuation, geometric_shapes, geometric_shapes_extended, latin-1_supplement, latin_extended-a, letterlike_symbols, mathematical_operators, miscellaneous_symbols, miscellaneous_symbols_and_pictographs, number_forms, ornamental_dingbats, superscripts_and_subscripts, supplemental_symbols_and_pictographs, symbols_and_pictographs_extended-a, transport_and_map_symbols]

This used to work fine with rofimoji 6.2.0. Now with 6.3.0, this happens:

$ rofimoji 
Traceback (most recent call last):

OSError: [Errno 36] File name too long: '/home/user/.local/share/rofimoji/recent/arrows-emojis-general_punctuation-geometric_shapes-geometric_shapes_extended-latin-1_supplement-latin_extended-a-letterlike_symbols-mathematical_operators-miscellaneous_symbols-miscellaneous_symbols_and_pictographs-number_forms-ornamental_dingbats-superscripts_and_subscripts-supplemental_symbols_and_pictographs-symbols_and_pictographs_extended-a-transport_and_map_symbols'

I see this is because of how __filename_for is defined:

https://github.com/fdw/rofimoji/blob/b3bac50137b75c940a00567a6e3e79730069a129/src/picker/recent.py#L47-L48

Here, files comes from either command-line arg --files or – in my case – from config file item files.

I'm able to work around this by instead abbreviating all the files with wildcards:

files = [arrows, emojis, general_punct*, geometric_shapes*, latin-1*, latin_extended-a, letterlike*, mathematical_op*, miscellaneous_symbols, miscellaneous_symbols_and_p*, number*, orna*, superscripts_*, supplemental_sym*, symbols_and_pictographs_extended-a, transport_*]

But clearly that is not a proper solution.

Perhaps this could be fixed by instead defining __filename_for as something like the following:

def __filename_for(files: List[str]) -> Path:
    return recents_file_location / hashlib.sha256(b'\0'.join(f.encode() for f in files)).hexdigest()

Okay, that was unexpected... but thanks very much for the report and your fix! I've updated main, maybe you can check it out 🙂

[c4rlo]

Thanks! I can confirm that this fixes it for me.

Thank you 🙂
