EShell is a fully POSIX compliant shell written entirely in Emacs Lisp, included with Emacs. |
|||
|
|||
* Config |
|||
|
|||
While not a traditional terminal emulator, it provides a native REPL for Emacs Lisp code, with everything in your configuration available in the environment. Make some slight configurations: |
|||
|
|||
+ Don't highlight the prompt |
|||
+ Favour use of system utilities |
|||
|
|||
#+begin_src emacs-lisp |
|||
(setq eshell-highlight-prompt nil |
|||
eshell-prefer-lisp-functions nil) |
|||
#+end_src |
|||
|
|||
* Extras |
|||
|
|||
Implement the lambda prompt for aesthetic purposes with the ~eshell-prompt-extras~ package. Here's an example of what that looks like: |
|||
|
|||
#+begin_example |
|||
~/.emacs.d/modules:main*? λ |
|||
#+end_example |
|||
|
|||
#+begin_src emacs-lisp |
|||
(use-package eshell-prompt-extras |
|||
:custom (eshell-prompt-function 'epe-theme-lambda)) |
|||
#+end_src |
|||
|
|||
* Shortcuts |
|||
|
|||
Open ~eshell~ in the current buffer with =SPC e=: |
|||
|
|||
#+begin_src emacs-lisp |
|||
(dotfiles/leader |
|||
"e" '(eshell :which-key "EShell")) |
|||
#+end_src |

Performing terminal interactions is a must-have for any modern editor. This module introduces *two* means of doing so with [[https://gnu.org/software/emacs/manual/html_node/eshell/index.html][EShell]][fn:1] and [[https://github.com/akermu/emacs-libvterm][VTerm]][fn:2]. |

** Prompt extras |
|||
|
|||
Implement the lambda prompt for aesthetic purposes with the [[https://github.com/zwild/eshell-prompt-extras][EShell Prompt Extras]][fn:3] package. |
|||
|
|||
#+begin_src emacs-lisp |

(use-package eshell-prompt-extras |

:custom (eshell-prompt-function 'epe-theme-lambda)) |

* Interactive Terminal |
|||
|
|||
*EShell*[fn:1] isn't enough when needing interactivity from the terminal. Going through [[https://chrishayward.xyz/notes/thinking-in-cpp/][Thinking in C++]] for one of my courses required lots of terminal interaction which *Eshell*[fn:1] was unable to handle. *VTerm's*[fn:2] based on an external C library which is blazing fast, and fully interactive. |

VTerm is an implementation of libvterm for Emacs. |

|

* Interactive Terminal |
|||
|
|||
I noticed ~eshell~ wasn't enough when needing interactivity from the terminal. Going through [[https://chrishayward.xyz/notes/thinking-in-cpp/][Thinking in C++]] for one of my courses required lots of terminal interaction which ~eshell~ was unable to handle. Since ~vterm~ is based on ~libvterm~, an external C library, it's blazing fast and fully interactive. Add a few configurations: |
|||
|
|||
+ Always compile the module |
|||
+ Install the required packages on *Debian/Ubuntu* |
|||
|
|||
#+begin_src emacs-lisp |
|||
(use-package vterm |
|||
:commands (vterm) |
|||
:custom (vterm-always-compile-module t)) |
|||
#+end_src |
|||
|
|||
* Shortcuts |
|||
|
|||
Open a new ~vterm~ buffer with =SPC v=: |
|||
|
|||
#+begin_src emacs-lisp |
|||
(dotfiles/leader |
|||
"v" '(vterm-other-window :which-key "VTerm")) |
