Colorschemes

ytop ships with a few colorschemes which can be set with the -c flag followed by the name of one. You can find all the colorschemes in the colorschemes folder.

To make a custom colorscheme, copy one of the default ones to ~/.config/ytop/.json and load it with ytop -c . Colorscheme PRs are welcome!

  • [WIP] Ability to not follow a process

    [WIP] Ability to not follow a process

    This introduces an ability to not-follow a process in the proc widget. I having to do gg whenever I visit ytop to find out the process which is currently using high mem/CPU. It'd be great to have the ability to not always track the currently highlighted process.

    This patch is a POC for that. What it does is:

    • Introduce a new flag on the widget: follow_proc, which is false by default. If it is set to true, the render will always jump to the position for the highlighted position. If it is false, it'll keep the selected position the same, no matter which process lands on it.
    • When ever the user does a scroll action (except gg), ytop will keep track of the process. gg or scroll to top on the other hand, stops the process tracking facilitating a view such as: the current process taking the most resources.
    • Also, bind Esc to set follow_proc as false and disable following of a process.

    I understand this cannot be merged as is, but I'd like to start a discussion. If this makes sense, I'd like suggestions on what can be changed in the patch to merge it in.

    I tried using another font with kitty (Fira Code Nerd Font Mono) but it doesn't make any difference.

    Any idea which settings I should tweak in order to get the same rendering than the VM one?

    Thanks.

    ~/.local/state/ytop/errors.log exists, but is empty.

    Problem

    On iMac (but not on older MacBooks) sysinfo provides - and ytop displays - wrong temperature. Note: I cloned sysinfo, and added some sensors (PECI CPU, and a couple more of such) to see what sensors report correctly on both Mac platforms). I found that all of those sensors give correct values on MacBook, but some fail on iMac Pro.

    Screen Shot 2020-08-02 at 21 25 01

    Proposed Workaround

    While we're discussing with @GuillaumeGomez the possibility of fixing sysinfo library - it would be nice if ytop could validate (sanity-check) inputs it receives from it. In this particular case, I'd love if ytop would check the received CPU temperature either against zero, or against CPU Proximity, and if it is lower (i.e., lower than zero, or lower than CPU Proximity) - ignore/drop that value and don't display it.

    Could you do that, please?

    Document automatic `-a` vs `-p` selection

    Some people have been rightfully confused (including myself when I first switched to ytop) that some computers will display all CPU cores, vs the average CPU usage. I think it would help if this detection was documented in the --help output next to the -a and -p flags saying something along the lines that it's the default if >= or < 8 cpu cores respectively.

If a minimum supported rust version was documented in the README and tested against with CI then hopefully people will understand the issue earlier.
