Question Mark Symbol

[Jev1337]

Describe the bug A question mark symbol on the graphs.

To Reproduce Just running the program.

Expected behavior No weird symbols

Screenshots

Environment Info

• OS: Windows 11
• Trippy version: 0.9.0
• Installation method: scoop install trippy

Additional context I hope this wasn't an already asked issue!

[Jev1337]

I would like to also ask how are settings changed in order to enable ASN info and Geolocation, which button to use?

[c-git]

Yes unfortunately this is an artifact of the terminal. IIRC it was powershell that does this. But if you use the normal cmd then it works fine. Please test in the other one and let me know if it still happens for you.

For this part I will have to test and get back to you as I don't normally use that feature. Or if if one of the others remember off hand and get to it before me they should be able to point you in the right direction.

[c-git]

I checked the readme in the usage examples section and I see it has an example of how to do geoip and while the program is running if you go to settings by pressing 's' I'd think you should see the file there. Let me know if this helps.

I'm using the normal cmd as admin, I tried PS 7 in case you meant the oposite but it's the same issue.

Even status indicator seems to be off compared to the readme's images.

[c-git]

One way to change the setting is to use the command line options to set it like it shows in the examples. If I recall correctly you can also use a settings file but try the command line option first as that's easier.

I'm using the normal cmd as admin, I tried PS 7 in case you meant the oposite but it's the same issue.

I know one of them was doing it. I don't remember which. I will try it hopefully later and let you know. I use Linux normally so I don't usually need to remember which one, but I will check for you.

@Jev1337 I'm not overly familiar with Windows, but from a brief search it does seem like there are known issues (and workarounds) for showing some unicode code pages and so this is not an issue specific to Trippy. The "best" solution seems to be to use Windows Console Preview whcih does not suffer from these issues.

Trippy (and in particular Ratatui, the TUI library) uses various unicode characters to display the charts and other things. Specifically, the Samples is a Ratatui Sparkline and uses the following unicode characters:

    pub const FULL: &str = "█";
    pub const SEVEN_EIGHTHS: &str = "▇";
    pub const THREE_QUARTERS: &str = "▆";
    pub const FIVE_EIGHTHS: &str = "▅";
    pub const HALF: &str = "▄";
    pub const THREE_EIGHTHS: &str = "▃";
    pub const ONE_QUARTER: &str = "▂";
    pub const ONE_EIGHTH: &str = "▁";

Thanks; I already tried changing fonts, reverting back to legacy cmd, and trying a windows 10 machine but nothing, I will try out the preview console later and report back!

@Jev1337 to add to what @c-git said and for the benefit of others who may ask a similar question in the future:

To enable AS lookup you use the --dns-lookup-as-info (-z) option. However, AS lookup is not supported for the default system DNS resolver and so you need to pick one of the others (i.e. Google's 8.8.8.8) with the --dns-resolve-method (-r) option. The command therefore becomes:

trip example.com -r google -z

To enable GeoIp information you need a MaxMind GeoIp mmdb database file, which you provide with the --geoip-mmdb-file (-G) option. Note that from Trippy 0.10.x, both MaxMind and IpInfo mmdb files may be used. You can optionally adjust how GeoIp information is displayed with the --tui-geoip-mode option. Therefore, your command could be:

trip example.com --geoip-mmdb-file GeoLite2-City.mmdb --tui-geoip-mode short

To avoid providing these options every time you run Trippy you can set them permanently in a trippy.toml config file.

Combining these, your config file would become:

[dns]
dns-resolve-method = "google"
dns-lookup-as-info = true

[tui]
geoip-mmdb-file = "/path/to/GeoLite2-City.mmdb"
tui-geoip-mode = "short"

Pressing 's' would show up the settings however I don't know how to change them

To confirm that the settings dialog is read-only for the moment, something we aim to improve in the future.

Hi @Jev1337 I tested and you're right both cmd and power shell show that. I tried windows terminal and that worked for me. I didn't install it so I'm guessing it came with Windows. I almost never boot up into windows so really not sure if I did it years ago.

I just typed terminal in the start menu then right clicked on the program in red and chose Run as Administrator and that worked.

Thank you both, trying out the "Terminal" instead of the normal CMD works, and the ASN functionality works as well!

By the way, I can't seem to find "geoip-mmdb-fil" in the settings, do I have to manually add it? Also while trying to use the config I get an UTF-8 Stream error

Are you able to share the file you use to get the stream error here?

@Jev1337 just to confirm you ONLY get this issue if you use the config file?

This config file seems identical to the default and both the default and the one copied work for me. I've uploaded the file I created with what I copied from this post with the .txt extension added as .toml files are not allowed by github. Could you download, remove the .txt extension and try it and let me know if you get the same error please.

trippy.toml.txt

Yes, I only get this if I use the config file, I remove it, trippy works as expected.

The file you gave me works as expected, however the auto generated template does not work for me.

Path: %APPDATA%

[c-git]

Interesting how do you generate the template? I want to see if I can reproduce the problem.

[fujiapple852]

Interesting how do you generate the template?

@c-git the template is generated with:

trip --print-config-template

This prints the contents of the trippy-config-sample.toml file that is baked into Trippy to stdout. Note that by baking the configuration file into Trippy we ensure that it matches the version of Trippy, so for example Trippy 0.9.0 has https://github.com/fujiapple852/trippy/blob/0.9.0/trippy-config-sample.toml baked into it.

The --print-config-template simply prints it:

fn print_config_template() {
    println!("{}", include_str!("../trippy-config-sample.toml"));
    process::exit(0);
}

So if the original file is valid utf-8 (it is) then so to will the output. However, I can reproduce the issue in a Windows 11 VM. I'll debug it.

I think what is happening is that the above is outputting UTF-16 LE encoding on Windows and so the file is rejected when later read, as Rust strings must be UTF-8.

[fujiapple852]

By the way, I can't seem to find "geoip-mmdb-fil" in the settings, do I have to manually add it?

@Jev1337 thanks for pointing this out, it was missing from the trippy-config-sample.toml. This is fixed now and will be correct in Trippy 0.10.0. For now you can just add it manually to the [tui] section:

# The mmdb file to use GeoIp lookup [default: none]
#
# Supported mmdb formats:
#   MaxMind "GeoLite2 City"
#   IPinfo "IP to Country + ASN Database"
#   IPinfo "IP to Geolocation Extended Database"
#geoip-mmdb-file = "/path/to/geoip_file.mmdb"

[c-git]

I think what is happening is that the above is outputting UTF-16 LE encoding on Windows and so the file is rejected when later read, as Rust strings must be UTF-8.

I think one possible solution might be to output directly to a file so the terminal can't mess it up. Either to the home directory or the current directory but I feel like the home directory might be better as I feel more users would want it there and then just output the path to the file. I don't think it's necessarily the best to get rid of the current feature but maybe add one that create a config file like maybe --init-config.

Edit: By home directory I mean the place where trippy would look for it anyway.

[Jev1337]

@Jev1337 thanks for pointing this out, it was missing from the trippy-config-sample.toml. This is fixed now and will be correct in Trippy 0.10.0.

Glad to be of help! Everything now works as expected!

Interesting how do you generate the template? I want to see if I can reproduce the problem.

As @fujiapple852 said but with redirection, via trip --print-config-template > .toml.

[c-git]

Thank you very much @Jev1337 glad everything works now.

[fujiapple852]

@Jev1337 @c-git Whilst not strictly a bug, I've added a fix that allows Trippy to read the configuration file in various encodings, including UTF-8 and UTF-16 LE such that it should "just work" on Windows.

See: https://github.com/fujiapple852/trippy/issues/958

See: #958

I did think of two solutions, either making it read various encodings like you did it or by adding another method that takes a path where to save the configuration file as UTF-8 rather than redirecting the std output to a file (for example --output-template <path>), but good to know that this is no longer a problem!
