Feature Request: Custom `.filemanager-ignore` support and `hideassets` toggle

[DOZ-Michael]

Hi,

I'm using your filemanager2 plugin and I love the improvements. However, I encountered a challenge when working in directories with problematic symlinks (e.g., disconnected network mounts or broken docker registries) or in environments where I don't have a Git repository.

Currently, the plugin relies on Git for ignoring files. In my setup, I implemented a surgical solution that adds a local ignore file support:

1. New Option: filemanager2.hideassets (true/false) to toggle custom filtering.
2. Custom Ignore File: A simple .filemanager-ignore file located in the plugin directory where users can list filenames or directories to hide.

Motivation

This prevents the plugin from scanning "poisonous" symlinks that can cause the editor to hang and provides a clean workspace even in non-Git environments. It makes the file tree much more stable and user-friendly for complex home directories.

Proposed Implementation Details

1. Option Registration:

   config.RegisterCommonOption('filemanager2', 'hideassets', true)

2. The Filter Logic:

   local function get_custom_ignore()
    local readout_results = {}
    local config_dir = config.ConfigDir
    local ignore_file_path = config_dir .. "/plug/filemanager2/.filemanager-ignore"
    local go_os = import("os")
    local _, err = go_os.Stat(ignore_file_path)
    if err == nil then
        local file = io.open(ignore_file_path, "r")
        if file then
            for line in file:lines() do
                local pattern = line:match("^%s*(.-)%s*$")
                if pattern ~= "" and string.sub(pattern, 1, 1) ~= "#" then
                    readout_results[#readout_results + 1] = pattern
                end
            end
            file:close()
        end
    end
    return readout_results
   end

3. Integration:
   Integrate get_custom_ignore() into the get_scanlist() function to filter results before they are processed.

I've already implemented this in my local version. Are you interested in a Pull Request for this feature?

Best regards,
Michael

Hi @DOZ-Michael

Appreciate the feedback. Yeah, it would be great if you could create a PR for it.

I would probably make the following changes/additions:

• Not sure if filemanager2.hideassets is necessary since it requires the user to explicitly create a file for it, or do you have a use case for it? (I would also rename it to filemanager2.ignorefiles instead)
• I would probably also add a local version too where the plugin would search in the current working directory to see what to ignore locally, similar to .gitignore.

You don't have to implement any of the above, but would be great if you can use a feature branch for the PR (instead of main) so that I can add commits to it.

Thanks

Actually, this should not happen and should be fixed as well. Are you able to reproduce the hang?
