This package is not likely to receive frequent updates, once fully stable. So how long ago the last commit was does not indicate project health.

Do you often find yourself fixing the indentation of a code snippet right after
|
|
pasting it somewhere? Never again! yank-indent is the answer.
|
|
|
|
## Features
|
|
|
|
- A fire-and-forget style global mode that does the right thing most of time.
|
|
Can be customized if you find it enables `yank-indent-mode` when it shouldn't.
|
|
- Configurable size threshold to prevent triggering indentation on very large
|
|
regions which may cause performance issues in with some major-modes.
|
|
|
|
## Installation
|
|
|
|
### use-package + straight.el
|
|
|
|
```elisp
|
|
(use-package yank-indent
|
|
:straight (:host github :repo "jimeh/yank-indent")
|
|
:config (global-yank-indent-mode t))
|
|
```
|
|
|
|
### Manual
|
|
|
|
Place `yank-indent.el` somewhere in your `load-path` and require it. For example
|
|
`~/.emacs.d/vendor`:
|
|
|
|
```elisp
|
|
(add-to-list 'load-path "~/.emacs.d/vendor")
|
|
(require 'yank-indent)
|
|
(global-yank-indent-mode t)
|
|
```
|
|
|
|
## Usage
|
|
|
|
### `global-yank-indent-mode`
|
|
|
|
With `global-yank-indent-mode` enabled, you will find that `yank-indent-mode` is
|
|
automatically enabled in relevant buffers. The defaults will specifically
|
|
exclude common languages which are indentation sensitive like Python, YAML,
|
|
Makefile, etc.
|
|
|
|
For fine-grained control over which major-modes it is enabled in or not, see
|
|
customization options with `M-x customize-group RET yank-indent`.
|
|
|
|
### `yank-indent-mode`
|
|
|
|
If you prefer not to use the global mode, you can add `yank-indent-mode` as a
|
|
hook to relevant major-modes, or even manually toggle it on and off with
|
|
`M-x yank-indent-mode`.
|
|
|
|
To skip the indent operation for a single yank command, use a prefix command, so
|
|
`C-u C-y` instead of just `C-y`.
|
|
|
|
Keep in mind that the include/exclude major-mode customizations only affect the
|
|
global mode and which buffers it enables `yank-indent-mode` in. If you
|
|
explicitly enable `yank-indent-mode` in a buffer, it will operate like normal
|
|
regardless of what major-mode the buffer is using.
|
|
|
|
## Under the Hood
|
|
|
|
`yank-indent` registers an advice for after `yank` and `yank-pop` commands. The
|
|
advice function verifies that `yank-indent-mode` mode is enabled in the current
|
|
buffer, prefix argument was not given, and the yanked/pasted text was within the
|
|
`yank-indent-threshold` in size. If all true, it will trigger indentation,
|
|
otherwise it does nothing.
