Using vim as pager
Use vim as a pager with the following features
- syntax highlighting should work
- "less" like key bindings (ex:- q for quit)
- preserve settings in ~/.vimrc
Assume that the user is using zsh and vim 7.4.
Add the following line to ~/.zshrc
Use it as
vless file.txt cat file.txt | vless
In some cases, the latter command does not detect the filetypes correctly . For example, while reading C++ programs through stdin, vim is setting the filetype to 'conf' instead of cpp. As a work around, set the file type on the command line.
cat prog.cpp | vless -c "set ft=cpp" -
- Instead of using /usr/share/vim/vim74/macros/less.sh, we can use "vim -u /usr/share/vim/vim74/macros/less.vim" . But this does not source standard configuration files such as ~/.vimrc . So all the custom settings will be lost.
Tested it on Debian Jessie (stable) using
% dpkg -l vim\* zsh\* | grep ^ii ii vim 2:7.4.488-7 amd64 Vi IMproved - enhanced vi editor ii vim-common 2:7.4.488-7 amd64 Vi IMproved - Common files ii vim-gtk 2:7.4.488-7 amd64 Vi IMproved - enhanced vi editor - with GTK2 GUI ii vim-gui-common 2:7.4.488-7 all Vi IMproved - Common GUI files ii vim-runtime 2:7.4.488-7 all Vi IMproved - Runtime files ii vim-tiny 2:7.4.488-7 amd64 Vi IMproved - enhanced vi editor - compact version ii zsh 5.0.7-5 amd64 shell with lots of features ii zsh-antigen 1-2 all manage your zsh plugins ii zsh-common 5.0.7-5 all architecture independent files for Zsh ii zsh-doc 5.0.7-5 all zsh documentation - info/HTML format
