Follow up to816fbcc26(patch 9.0.1833: [security] runtime file fixes, 2023-08-31) andf7ac0ef50(runtime: don't execute external commands when loading ftplugins, 2023-09-06). This puts the logic for safe executable checks in a single place, by introducing a central vim library, so all filetypes benefit from consistency. Notable changes: - dist#vim because the (autoload) namespace for a new runtime support library. Supporting functions should get documentation. It might make life easier for NeoVim devs to make the documentation a new file rather than cram it into existing files, though we may want cross-references to it somewhere… - The gzip and zip plugins need to be opted into by enabling execution of those programs (or the global plugin_exec). This needs documentation or discussion. - This fixes a bug in the zig plugin: code setting s:tmp_cwd was removed inf7ac0ef50(runtime: don't execute external commands when loading ftplugins, 2023-09-06), but the variable was still referenced. Since the new function takes care of that automatically, the variable is no longer needed. Signed-off-by: D. Ben Knoble <ben.knoble+github@gmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
The ftplugin directory is for Vim plugin scripts that are only used for a specific filetype. All files ending in .vim in this directory and subdirectories will be sourced by Vim when it detects the filetype that matches the name of the file or subdirectory. For example, these are all loaded for the "c" filetype: c.vim c_extra.vim c/settings.vim Note that the "_" in "c_extra.vim" is required to separate the filetype name from the following arbitrary name. The filetype plugins are only loaded when the ":filetype plugin" command has been used. The default filetype plugin files contain settings that 95% of the users will want to use. They do not contain personal preferences, like the value of 'shiftwidth'. If you want to do additional settings, or overrule the default filetype plugin, you can create your own plugin file. See ":help ftplugin" in Vim.
