conda-inherit

Automatically inherit conda/mamba/micromamba environments when creating new tmux panes or windows.

Description

When you split a tmux pane, your conda environment resets to base.
This plugin fixes that by automatically activating the parent pane's environment in new panes and windows.
No manual activation needed!

Features:

• Automatic environment inheritance from parent panes
• Works with conda, mamba, and micromamba
• Supports bash, zsh, and fish
• Automatic cleanup of closed panes
• Lightweight with minimal performance impact

Requirements

• tmux >= 3.0
• tpm (Tmux Plugin Manager)
• bash, zsh, or fish
• conda/mamba/micromamba (Initialized in your shell)

Installation

tmux configuration

Add to ~/.config/tmux/tmux.conf or ~/.tmux.conf:

# Install plugin via TPM
set -g @plugin 'oluevaera/tmux-conda-inherit'

# Add -e "TMUX_PARENT_PANE_ID=#{pane_id}" to your window split/new keybinds
bind '%' run 'tmux split-window -c "#{pane_current_path}" -e "TMUX_PARENT_PANE_ID=#{pane_id}" -h'
bind '"' run 'tmux split-window -c "#{pane_current_path}" -e "TMUX_PARENT_PANE_ID=#{pane_id}" -v'
bind c run 'tmux new-window -c "#{pane_current_path}" -e "TMUX_PARENT_PANE_ID=#{pane_id}"'

Shell configuration

Add after conda initialization block:

Bash/Zsh (~/.bashrc or ~/.zshrc):

if [[ -n "$TMUX" ]]; then
  export flavor='micromamba'  # Change to 'conda' or 'mamba' if needed
  source ~/.config/tmux/plugins/tmux-conda-inherit/conda-inherit.sh
fi

Fish (~/.config/fish/config.fish):

if set -q TMUX
    set -g flavor micromamba  # Change to 'conda' or 'mamba' if needed
    source ~/.config/tmux/plugins/tmux-conda-inherit/conda-inherit.fish
end
