Allow opening files from picker

[anandkumar89]

since the BibTeX file is used - this file also contains file: path_to_file. I am looking for ways to open this file from picker with a keybinding in external pdf reader e.g. open ...

How can one go about extending telescope-bibtex for this purpose?

Note for people interested :

I added a shortcut when setting up bibtex extension for telescope as below to open pdf files in desired app. For me, Sioyek.

This was inspired by solutions in #20, and help from chatGPT.

local bibtex_actions = require('telescope-bibtex.actions')
local action_state  = require('telescope.actions.state')
local actions 		= require('telescope.actions')
local job 			= require('plenary.job')
require('telescope').setup({
	extensions = {
		bibtex = {
			depth=2,
			format='plain',
			global_files = {'~/Dropbox/Apps/Overleaf/bib/online.bib', '~/Dropbox/Apps/Overleaf/bib/library.bib'},
			search_keys = {'author', 'year', 'title'},
			context = true,
			mappings = {
				    i = {
						["<CR>"] = function(prompt_bufnr)
							local entry = action_state.get_selected_entry().id.content
							-- local files = {} -- TODO handle multiple files, show harpoon like UI to select file
							-- local extensions = {}
							actions.close(prompt_bufnr)
							entry = table.concat(entry, "\n")
							for paths in entry:gmatch("file%s*=%s*{([^}]+)}") do
								for path in paths:gmatch("[^,]+") do
    									path = vim.trim(path)
    									local ext  = path:match("^.+%.(.+)$")
    									-- table.insert(files, path)
    									-- table.insert(extensions,ext)
    									if ext == "pdf" then
    											job:new({
    											  command = "/Applications/sioyek.app/Contents/MacOS/sioyek",
    											  args = { path },
    											  detached = true,
    											}):start()
    									end
    								end
    							end
    					  end,
					  }
				 },
			wrap = true,
			}
		}
})
require('telescope').load_extension("bibtex")
