Here is an AppleScript script to make it possible double-click files in Finder so that they will be opened in Vim, by Normen Hansen: https://github.com/normen/vim-macos-scripts/blob/master/open-file-in-vim.applescript (it must be used from Automator). I try to simplify it and also to make it possible to use it without Automator. To use my own version, you only need to save it as application instead, like this: osacompile -o open-with-vim.app open-with-vim.applescript and then copy it to /Applications and set your .txt files to be opened using this app. Here it is, it alsmost works: -- https://github.com/normen/vim-macos-scripts/blob/master/open-file-in-vim.applescript -- opens Vim with file or file list -- sets current folder to parent folder of first file on open theFiles set command to {} if input is null or input is {} or ((item 1 in input) as string) is "" then -- no files, open vim without parameters set end of command to "vim;exit" else set firstFile to (item 1 of theFiles) as string tell application "Finder" to set pathFolderParent to quoted form of (POSIX path of ((folder of item firstFile) as string)) set end of command to "cd" & space & (pathFolderParent as string) set end of command to ";hx" -- e.g. vi or any other command-line text editor set fileList to {} repeat with i from 1 to (theFiles count) set end of fileList to space & quoted form of (POSIX path of (item i of theFiles as string)) end repeat set end of command to (fileList as string) set end of command to ";exit" -- if Terminal > Settings > Profiles > Shell > When the shell exits != Don't close the window end if set command to command as string set myTab to null tell application "Terminal" if it is not running then set myTab to (do script command in window 1) else set myTab to (do script command) end if activate end tell return end open The only problem is the if block in the very beginning: if input is null or input is {} or ((item 1 in input) as string) is "" then What is wrong here? How to make it work? (Assuming it already works fine if AppleScript is used using Automator.)
