Handle missing capture file destination and report to user

[milanglacier]

Describe the bug

when try to use capture template with a non default target file and a specified headline, get the following error:

Error executing vim.schedule lua callback: ...ite/pack/packer/opt/orgmode/lua/orgmode/capture/init.lua:230: attempt to index local 'destination_file' (a nil val
ue)
stack traceback:
        ...ite/pack/packer/opt/orgmode/lua/orgmode/capture/init.lua:230: in function 'refile_to_headline'
        ...ite/pack/packer/opt/orgmode/lua/orgmode/capture/init.lua:124: in function ''
        vim/_editor.lua: in function ''
        vim/_editor.lua: in function <vim/_editor.lua:0>

Steps to reproduce

1. <Leader>oc to open the org capture
2. select the template, say t, which will write the buffer to a non default file with a specified headline.
3. press C-c, and get the error

Expected behavior

write the buffer to the specified file with a specified headline

Emacs functionality

write the buffer to the specified file with a specified headline

Minimal init.lua

vim.cmd [[set runtimepath=$VIMRUNTIME]]
vim.cmd [[set packpath=/tmp/nvim/site]]

local package_root = '/tmp/nvim/site/pack'
local install_path = package_root .. '/packer/start/packer.nvim'

local function load_plugins()
    require('packer').startup {
        {
            'wbthomason/packer.nvim',
            { 'nvim-treesitter/nvim-treesitter' },
            { 'kristijanhusak/orgmode.nvim', branch = 'master' },
        },
        config = {
            package_root = package_root,
            compile_path = install_path .. '/plugin/packer_compiled.lua',
        },
    }
end

_G.load_config = function()
    require('orgmode').setup_ts_grammar()
    require('nvim-treesitter.configs').setup {
        highlight = {
            enable = true,
            additional_vim_regex_highlighting = { 'org' },
        },
    }

    vim.cmd [[packadd nvim-treesitter]]
    vim.cmd [[runtime plugin/nvim-treesitter.lua]]
    vim.cmd [[TSUpdateSync org]]

    -- Close packer after install
    if vim.bo.filetype == 'packer' then
        vim.api.nvim_win_close(0, true)
    end

    local org_dir = '~/Desktop/orgmode' -- change this line to an org dir
    require('orgmode').setup {
        org_agenda_files = { org_dir .. '/*' },
        org_default_notes_file = org_dir .. '/capture/todo.org',
        org_capture_templates = {
            n = {
                description = 'personal notes',
                template = '** %u %?',
                target = org_dir .. '/capture/notes.org',
                headline = 'Notes'
            },
        },
    }

    -- Reload current file if it's org file to reload tree-sitter
    if vim.bo.filetype == 'org' then
        vim.cmd [[edit!]]
    end
end

if vim.fn.isdirectory(install_path) == 0 then
    vim.fn.system { 'git', 'clone', 'https://github.com/wbthomason/packer.nvim', install_path }
    load_plugins()
    require('packer').sync()
    vim.cmd [[autocmd User PackerCompileDone ++once lua load_config()]]
else
    load_plugins()
    load_config()
end

and the target org dir, say ~/Desktop/orgmode, needs to have the following file, capture/notes.org, with the following cotents

* Notes

Does file ~/Desktop/orgmode/capture/notes.org exist? It seems that it cannot be reached when capturing.

yes, it does contain, for sure.

Can you try to pull latest master and give it another try?

Hi! The error is still there. Since ~/Desktop/orgmode/capture/notes.org does exist, I think the issue does not come from there.

[kristijanhusak]

This is because you need to set org_agenda_files to also find files in subdirectories, like this:

org_agenda_files = { org_dir .. '/**/*' },

Problem is that your notes.org file is in the capture folder, and it is not your default file, so it's not considered.

[milanglacier]

thank you. This is the true reason.
