TagList vim plugin is not working

I have issues in using taglist. For example if I TlistOpen, it shows an error E117: Unknown function: taglist#Tlist_Window_Toggle

I am using a Ubuntu18.04 , with vimrc looks like as follows;

test@test-VirtualBox:~/.vim/taglist/plugin$ cat ~/.vimrc set nocompatible " be iMproved, required filetype off " required " set the runtime path to include Vundle and initialize set rtp+=~/.vim/bundle/Vundle.vim set rtp+=~/.vim/taglist/plugin/ call vundle#begin() " alternatively, pass a path where Vundle should install plugins "call vundle#begin('~/some/path/here') " let Vundle manage Vundle, required Plugin 'VundleVim/Vundle.vim' " The following are examples of different formats supported. " Keep Plugin commands between vundle#begin/end. " plugin on GitHub repo Plugin 'tpope/vim-fugitive' " plugin from " Plugin 'L9' " Git plugin not hosted on GitHub Plugin 'git:// " git repos on your local machine (i.e. when working on your own plugin) Plugin 'file:///home/gmarik/path/to/plugin' " The sparkup vim script is in a subdirectory of this repo called vim. " Pass the path to set the runtimepath properly. Plugin 'rstacruz/sparkup', {'rtp': 'vim/'} " Install L9 and avoid a Naming conflict if you've already installed a " different version somewhere else. " Plugin 'ascenator/L9', {'name': 'newL9'} Plugin 'taglist.vim' " All of your Plugins must be added before the following line call vundle#end() " required filetype plugin indent on " required " To ignore plugin indent changes, instead use: "filetype plugin on " " Brief help " :PluginList - lists configured plugins " :PluginInstall - installs plugins; append `!` to update or just :PluginUpdate " :PluginSearch foo - searches for foo; append `!` to refresh local cache " :PluginClean - confirms removal of unused plugins; append `!` to auto-approve removal " " see :h vundle for more details or wiki for FAQ " Put your non-Plugin stuff after this line set tags=/home/test/code/tags 

I have my taglist cloned to .vim/taglist/plugin. My Exuberant Ctags is installed in /usr/bin/ctags and the path is available in PATH. I have installed the vim plugin manager vundle. I have my cscope and ctags set for the directory code. However when I TlistOpen in vim, it throws an error message E117: Unknown function: taglist#Tlist_Window_Toggle

Let's start by removing all the comment noise from your vimrc:

set nocompatible " be iMproved, required filetype off " required set rtp+=~/.vim/bundle/Vundle.vim set rtp+=~/.vim/taglist/plugin/ call vundle#begin() Plugin 'VundleVim/Vundle.vim' Plugin 'tpope/vim-fugitive' Plugin 'git:// Plugin 'file:///home/gmarik/path/to/plugin' Plugin 'rstacruz/sparkup', {'rtp': 'vim/'} Plugin 'taglist.vim' call vundle#end() " required filetype plugin indent on " required set tags=/home/test/code/tags 

as well as the examples that Vundle's README.md tells you to remove:

set nocompatible " be iMproved, required filetype off " required set rtp+=~/.vim/bundle/Vundle.vim set rtp+=~/.vim/taglist/plugin/ call vundle#begin() Plugin 'VundleVim/Vundle.vim' Plugin 'taglist.vim' call vundle#end() " required filetype plugin indent on " required set tags=/home/test/code/tags 

and the irrelevant boilerplate:

set rtp+=~/.vim/bundle/Vundle.vim set rtp+=~/.vim/taglist/plugin/ call vundle#begin() Plugin 'VundleVim/Vundle.vim' Plugin 'taglist.vim' call vundle#end() " required set tags=/home/test/code/tags 

The first thing that catches the eye is that you are trying to manage that plugin both manually:

set rtp+=~/.vim/taglist/plugin/ 

and with your plugin manager:

Plugin 'taglist.vim' 

which doesn't make any sense.

The second thing that catches the eye is that you are adding ~/.vim/taglist/plugin/ to :help 'runtimepath' instead of ~/.vim/taglist/, which prevents Vim from finding ~/.vim/taglist/autoload/ and thus from being able to call taglist#Tlist_Window_Toggle().

Changing:

set rtp+=~/.vim/taglist/plugin/ 

to:

set rtp+=~/.vim/taglist/ 

should temporarily get you out of trouble but you will still be left with a mess.

I would suggest you abandon the manual method and let your plugin manager handle everything:

1. Delete ~/.vim/taglist/ from your machine.
2. Remove set rtp+=~/.vim/taglist/ from your vimrc.
3. Replace Plugin 'taglist.vim' with Plugin 'yegappan/taglist' in your vimrc.
4. Read your plugin manager's documentation to get familiar with it.
