Are there any built-in functions to search sorted list? Such as binary_search, lower_bound, upper_bound, etc.

    I don't think so. I have used vimgrep to find something like that but came up empty. – klaus Apr 9 at 1:50
  • Why do you need this? Vim has functions to search lists—do you need performance for a large data set? Push the code to a different level (ie out of vimscript), unless vim can expose the binary search mechanism it uses for tagsfiles. – D. Ben Knoble Apr 9 at 6:14
  • Don't really need it, just curious. – dedowsdi Apr 9 at 6:32

There is nothing built in. But you might check lh-vim-lib.

It has the following functions working on sorted lists:

  • lh#list#equal_range()
  • lh#list#lower_bound()
  • lh#list#upper_bound()

    I do indeed provide these functions, but they are quite likely to be less efficient than a naive call to filter(). You'll have to measure both to see what's better suited to the data you're manipulating in your plugins. – Luc Hermitte Apr 9 at 11:09
