Descripción

## Expected behavior

in evil mode w motion should work on clojure symbols for example: this-symbol?!

## Actual behavior

currently the motion will only include 'this' - i.e up to to the hyphen.

## Steps to reproduce the problem

std doom-emacs with clojure mode

## Environment & Version information

### clojure-mode version

```
clojure-mode (version 5.16.0)
```

### Emacs version

GNU emascs 27.1

### Operating system

Linux 5.15.0-67-generic #74-Ubuntu SMP Wed Feb 22 14:14:39 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

# Suggested change

I am not too familiar with emacs lisp or the clojure mode so this is just a suggestion - it has worked for me in my local configs.

add the following extensions to the word syntax definitions in the clojure-mode-syntax-table (there may be a more compact way of expressing that but I am not familiar with required syntax).

you may or may not want to include the # character. I found it useful and it is accepted in symbols

I am not certain how/if to this should be changed where a character is not allowed as the first char of a word....

I note also that motions like yW are a problem because they pick up brackets when at the end of an expression. So I also included # / : and . because these are useful. There may be a better way to include these...

```
;; word syntax: add clojure symbol characters
;; as per https://clojure.org/reference/reader
(modify-syntax-entry ?* "w" table)
(modify-syntax-entry ?+ "w" table)
(modify-syntax-entry ?! "w" table)
(modify-syntax-entry ?- "w" table)
(modify-syntax-entry ?_ "w" table)
(modify-syntax-entry ?' "w" table)
(modify-syntax-entry ?? "w" table)
(modify-syntax-entry ?< "w" table)
(modify-syntax-entry ?> "w" table)

;; word-syntax: and other characters that
;; are useful in word motions
(modify-syntax-entry ?# "w" table)
(modify-syntax-entry ?/ "w" table)
(modify-syntax-entry ?: "w" table)
(modify-syntax-entry ?. "w" table)
```

Línea de trabajo

Localiza clojure-mode-syntax-table y revisa primero sus entradas existentes de sintaxis de palabras. Reproduce el comportamiento de Evil-mode para w y W con this-symbol?! y compáralo con los caracteres de símbolo de Clojure propuestos, incluidos #, /, : y .. Se considera terminado cuando los caracteres previstos se gestionan de forma coherente mediante los movimientos por palabras, sin absorber incorrectamente los corchetes circundantes.
