how to change the style of the filtered prefix in the autocomplete menu?

[simonLeary42]

it's shown as bold, but I'd like it to pop a bit more. Looking around ble-face I saw that there is a highlight on the input line called menu_filter_input, and I saw that menu_filter_fixed was equal to bold. But then I changed menu_filter_fixed and nothing happened. No other style in ble-face uses bold.

while looking at my theme I noticed that all the filename_* styles are not actually in effect since I set bleopt filename_ls_colors=$LS_COLORS.

ble.sh doesn't provide the configuration interface for this.

it's shown as bold, but I'd like it to pop a bit more.

Unless it doesn't have a functional issue, I'd call it a preference. As I've explained in https://github.com/akinomyoga/ble.sh/issues/518#issuecomment-2401155760, I'm reluctant to add an option for every preference. If you want to adjust the behavior, you can modify ble.sh. The code that boldfaces the matching part is contained in the shell function ble/complete/menu-complete.class/render-item.

Looking around ble-face I saw that there is a highlight on the input line called menu_filter_input, and I saw that menu_filter_fixed was equal to bold. But then I changed menu_filter_fixed and nothing happened.

The faces menu_filter_input and menu_filter_fixed are unrelated to the faces used to show the menu items. As their names contain menu_filter, they are the faces for the menu_filter feature.

Yes, it's documented.

If there are other reasons I might implement it (e.g. if other shells have a similar configuration). Hmm, Fish's fish_pager_color_prefix seems to be that.

It's not that I want to make it pretty, it's that it's difficult to read, I have to squint. In my case it's filenames with unix timestamps in them, so a long string of numbers with a common prefix. I have to look at the files in the autocomplete menu, find the border between "already typed" and "not typed yet", and then find out which file is newer by comparing the first number to the right of said border.

GNU readline colors this prefix when colored-completion-prefix is enabled, and for some reason it uses the value from LS_COLORS for a socket.

That seems to imply that the boldface in your terminal is always difficult to distinguish from the normal font width, and thus it seems an issue with the terminal font setting.

GNU readline colors this prefix when colored-completion-prefix is enabled, and for some reason it uses the value from LS_COLORS for a socket.

The information in the link seems to be old. Bash >= 5.2 has the *.readline-colored-completion-prefix entry in LS_COLORS for the Readline setting colored-completion-prefix on.

Since fish and readline seem to support something, I'll add something, but it may take time. I'm busy.
