Vim File Searching: Upward and Combined Up/Downward Search and Trusted Files

The system also has a limit on the path length, usually 256 or 1024 bytes. - "**" can only be at the end of the path or be followed by a path separator or by a number and a path separator. You can combine "*" and "**" in any order: > /usr/**/sys/* /usr/*tory/sys/** /usr/**2/sys/* 2) Upward search: Here you can give a directory and then search the directory tree upward for a file. You could give stop-directories to limit the upward search. The stop-directories are appended to the path (for the 'path' option) or to the filename (for the 'tags' option) with a ';'. If you want several stop-directories separate them with ';'. If you want no stop-directory ("search upward till the root directory") just use ';'. > /usr/include/sys;/usr < will search in: > /usr/include/sys /usr/include /usr < If you use a relative path the upward search is started in Vim's current directory or in the directory of the current file (if the relative path starts with './' and 'd' is not included in 'cpoptions'). If Vim's current path is /u/user_x/work/release and you do > :set path=include;/u/user_x < and then search for a file with |gf| the file is searched in: > /u/user_x/work/release/include /u/user_x/work/include /u/user_x/include < Note: If your 'path' setting includes a non-existing directory, Vim will skip the non-existing directory, and also does not search in the parent of the non-existing directory if upwards searching is used. 3) Combined up/downward search: If Vim's current path is /u/user_x/work/release and you do > set path=**;/u/user_x < and then search for a file with |gf| the file is searched in: > /u/user_x/work/release/** /u/user_x/work/** /u/user_x/** < BE CAREFUL! This might consume a lot of time, as the search of '/u/user_x/**' includes '/u/user_x/work/**' and '/u/user_x/work/release/**'. So '/u/user_x/work/release/**' is searched three times and '/u/user_x/work/**' is searched twice. In the above example you might want to set path to: > :set path=**,/u/user_x/** < This searches: > /u/user_x/work/release/** /u/user_x/** < This searches the same directories, but in a different order. Note that completion for ":find", ":sfind", and ":tabfind" commands do not currently work with 'path' items that contain a URL or use the double star with depth limiter (/usr/**2) or upward search (;) notations. ============================================================================== 12. Trusted Files *trust* Nvim executes arbitrary code found on the filesystem if 'exrc' is enabled. To prevent executing malicious code, only "trusted files" are executed. You can mark a file as trusted or untrusted using the |:trust| command or the |vim.secure.read()| function. *:trust* *E5570* :trust [++deny] [++remove] [file] Manage trusted files. Without ++ options, :trust marks the current buffer as trusted, keyed on a hash of its contents. The trust list is stored on disk, Nvim will re-use it after restarting. [++deny] marks [file] (or current buffer if no [file]) as untrusted: it will never be executed, 'exrc' will ignore it. [++remove] removes [file] (or current buffer if no [file]) from the trust list. When the file is discovered by 'exrc' or |vim.secure.read()|, the user will be asked whether to trust or deny the file. vim:tw=78:ts=8:noet:ft=help:norl:

This section describes upward and combined up/downward file searching in Vim. Upward search involves traversing the directory tree upwards to find a file, with the option to specify stop-directories. Combined search merges upward and downward search, but may cause redundant searches. The section also discusses trusted files in Vim and introduces the `:trust` command to manage trusted files, which are executed when 'exrc' is enabled. It covers options to mark files as trusted, untrusted (denied), or remove them from the trust list. When an untrusted file is discovered, the user is asked whether to trust or deny the file.
