Moving panes between tmux sessions is something that makes tmux a very flexible and powerful tool. I don’t need this feature very often, but it comes in clutch when you need it. Pull a pane from any other session # [1] Using choose-window I was able to come up with a way to select any pane withing any other session and join it into my current session. # Choose a pane to join in horizontally bind f choose-window -Z 'join-pane -h -s "%%"' Push/Pull from scratch # [2] I’ve long had this one in my tmux config, I always have a “scratch” session that I’m running, I often use for looking at things like k9s accross repos within a popup. This use case puts a pane into the scratch session, then pulls it back out. I will use this to move a pane between sessions in the rare cases I need to do this. # push the active pane into the scratch session horizonally bind -n M-f join-pane -ht scratch # pull the last active pane from the scratch session horizonally into this session bind -n M-F join-pane -hs scratch References: [1]: #pull-a-pane-from-any-other-session [2]: #pushpull-from-scratch

I love the freedom of writing in markdown. It allows me to write content from the comfort of my editor with very little focus on page style. It turns out that markdown is also a fantastic tool for creating slides. Present from the terminal # [1] I will most often just present right from the terminal using lookatme [2]. Presenting from the terminal lets me see the results quick right from where I am editing. It also allows me to pop into other terminal applications quickly. reveal.js # [3] I sometimes also use reveal.js, but that’s for another post. It is handy that it lives in the browser and is easier to share. New Slides # [4] I leverage auto slides when I write my slides in markdown. The largest heading, usually an h2 for me, becomes the new slide marker. Otherwise my process is not much different, It just becomes a shorter writing style. Installation # [5] lookatme is a python library that is available on pypi, you can install it with the pip command. python -m pip install lookatme Since it’s a command line application it works great with pipx. This prevents the need to manage virtual environments yourself or ending up with packages clashing in your system python e...

I recently found a really great plugin [1] by mhinz [2] to open files in neovim from a different tmux split, without touching neovim at all. Installation # [3] neovim-remote [1] is not a neovim plugin at all, it’s a python cli that you can install with pip. Unlike the repo suggests, I use pipx to install nvr. pipx install neovim-remote How I use it # [4] I have this added to my .envrc that is in every one of my projects. This will tie a neovim session to that directory, and all directories under it. export NVIM_LISTEN_ADDRESS=/tmp/nvim-$(basename $PWD) In my workflow I open a tmux session for each project, so this essentially ties a neovim session to a tmux session. Open neovim # [5] First open neovim, but with the nvr command. This will open neovim, and look pretty much the same as always. nvr If you try to run nvr again in another shell nothing will happen as its already runnin under that address, but if you give it a filename it will open the file in the first instance of neovim that you opened. nvr readme.md Links # [6] - GitHub [1] References: [1]: https://github.com/mhinz/neovim-remote [2]: https://github.com/mhinz [3]: #installation [4]: #how-i-use-it [5]: #op...

As I am toying around with textual, I am wanting some popup user input to take over. Textual is still pretty new and likely to change quite significantly, so I don’t want to overdo the work I put into it, So for now on my personal tuis I am going to shell out to tmux. The Problem # [1] The main issue is that when you are in a textual app, it kinda owns the input. So if you try to run another python function that calls for input it just cant get there. There is a textual-inputs [2] library that covers this, and it might work really well for some use cases, but many of my use cases have been for things that are pre-built like copier, and I am trying to throw something together quick. textual is still very beta Part of this comes down to the fact that textual is still very beta and likely to change a lot, so all of the work I have done with it is for quick and dirty, or fun side projects. The Solution # [3] So the solution that was easiest for me… shell out to a tmux popup. The application I am working on wants to create new documents using copier templates. copier has a fantastic cli that walks throught he template variables and asks the user to fill them in, so I just shell...

The default keybinding for copy-mode <prefix>-[ is one that is just so awkward for me to hit that I end up not using it at all. I was on a call with my buddy Nic this week and saw him just fluidly jump into copy-mode in an effortless fashion, so I had to ask him for his keybinding and it just made sense. Enter, that’s it. So I have addedt his to my ~/.tmux.conf along with one for alt-enter and have found myself using it way more so far. Setting copy-mode to enter # [1] To do this I just popped open my ~/.tmux.conf and added the following. Now I can get to copy-mode with <prefix>-Enter which is control-b Enter, or alt-enter. bind Enter copy-mode bind -n M-Enter copy-mode More on copy-mode # [2] I have a full video on copy-mode you can find here. tmux copy-mode [3] References: [1]: #setting-copy-mode-to-enter [2]: #more-on-copy-mode [3]: /tmux-copy-mode/

One of the first things I noticed broken in my terminal based workflow moving from Windows wsl to ubuntu was that my clipboard was all messed up and not working with my terminal apps. Luckily setting tmux and neovim to work with the system clipboard was much easier than it was on windows. First off you need to get xclip if you don’t already have it provided by your distro. I found it in the apt repositories. I have used it between Ubuntu 18.04 and 21.10 and they all work flawlessly for me. I have tmux setup to automatically copy any selection I make to the clipboard by setting the following in my ~/.tmux.conf. While I have neovim open I need to be in insert mode for this to pick up. # ~/tmux.conf bind -T copy-mode-vi Enter send-keys -X copy-pipe-and-cancel "xclip -i -f -selection primary | xclip -i -selection clipboard" bind-key -T copy-mode-vi MouseDragEnd1Pane send-keys -X copy-pipe-and-cancel "xclip -selection clipboard -i" To get my yanks to go to the system clipboard in neovim, I just added unnamedplus to my existing clipboard variable. # ~/.config/nvim/init.vim set clipboard+=unnamedplus If you need to copy something right from the terminal you can use xclip directly. ...

I have added a hotkey to my copier template setup to quickly access all my templates at any time from tmux. At any point I can hit <c-b><c-b>, thats holding control and hitting bb, and I will get a popup list of all of my templates directory names. Its an fzf list, which means that I can fuzzy search through it for the template I want, or arrow key to the one I want if I am feeling insane. I even setup it up so that the preview is a list of the files that come with the template in tree view. bind-key c-b popup -E -w 80% -d '#{pane_current_path}' "\ pipx run copier copy ~/.copier-templates/`ls ~/.copier-templates |\ fzf --header $(pwd) --preview='tree ~/.copier-templates/{} |\ lolcat'` . \ " I’ve had this on my systems for a few weeks now and I am constantly using it for my tils [1], blogs [2], and my .envrc file that goes into all of my projects to make sure that I have a virtual environment [3] installed and running any time I open it.

tmux popups can be sized how you like based on the % width of the terminal on creation by using the flags (h, w, x, y) for height, width, and position. # normal popup tmux popup figlet "Hello" # fullscreen popup tmux popup -h 100% -w 100% figlet "Hello" # 75% centered popup tmux popup -h 100% -w 75% figlet "Hello" # 75% popup on left side tmux popup -h 100% -w 75% -x 0% figlet "Hello" Sorry, your browser doesn't support embedded videos. example running these commands
