Should rulerfmt be replaced with a ruler template file?

[joelim-work]

A few weeks ago I was exploring the idea of using Go templates as a replacement for the rulerfmt configuration syntax. The idea is that a template file allows for greater customization (in particular control flow via if/else statements, at the cost of greater complexity. A more detailed writeup is located at #2084, and there is also an outstanding draft pull request at #2083 (I do not plan to merge it unless there is sufficient interest from other users).

Anyway I just thought I would try to gauge whether users are interested in the feature or not. Here is a quick comparison of what the default ruler looks like between the two approaches:

rulerfmt (and statfmt):

set statfmt "\033[36m%p\033[0m| %c| %u| %g| %S| %t| -> %l"
set rulerfmt "%a|  %p|  \033[7;31m %m \033[0m|  \033[7;33m %c \033[0m|  \033[7;35m %s \033[0m|  \033[7;34m %f \033[0m|  %i/%t"

ruler template file:

{{with .Message -}}
    {{. -}}
{{else with .Stat -}}
    {{.Permissions | printf "\033[36m%s\033[0m" -}}
    {{with .LinkCount}} {{.}}{{end -}}
    {{with .User}} {{.}}{{end -}}
    {{with .Group}} {{.}}{{end -}}
    {{.Size | humanize | printf " %5s" -}}
    {{.ModTime | printf " %s" -}}
    {{with .Target}} -> {{.}}{{end -}}
{{end -}}
{{.SPACER -}}
{{with .Keys}}  {{.}}{{end -}}
{{with .Progress}}  {{join . " "}}{{end -}}
{{with .Copy}}  {{len . | printf "\033[7;33m %d \033[0m"}}{{end -}}
{{with .Cut}}  {{len . | printf "\033[7;31m %d \033[0m"}}{{end -}}
{{with .Select}}  {{len . | printf "\033[7;35m %d \033[0m"}}{{end -}}
{{with .Visual}}  {{len . | printf "\033[7;36m %d \033[0m"}}{{end -}}
{{with .Filter}}  {{join . " " | printf "\033[7;34m %s \033[0m"}}{{end -}}
{{printf "  %d/%d" .Index .Total}}
