如何在Emacs中大寫英文字符串

Question

我想知道人們使用什么來正確地大寫英文字符串，因為“ capitalize”將無法完成工作：

(capitalize "can't")
=> "Can'T"

盡管編寫此函數很簡單，但我想知道是否存在一種首選的內置方法來實現。

Answer 1

也許如果您暫時將'添加到當前單詞構成語法表中：

(modify-syntax-entry ?' "w")

(capitalize "can't")
=> "Can't"

Answer 2

我有Mc一定要大寫單詞，並且它can't正確地大寫。

Answer 3

當前的答案很好，但是如果您在代碼中使用字符串，則可以使用s字符串操作庫。 s-capitalize將句子中的第一個單詞大寫。

ELISP> (s-capitalize "can't win the war on drugs in a prison, where the hell you gonna win it?")
"Can't win the war on drugs in a prison, where the hell you gonna win it?"
ELISP> (s-join " " (-map 's-capitalize (s-split " " "can't win the war on drugs in a prison, where the hell you gonna win it?")))
"Can't Win The War On Drugs In A Prison, Where The Hell You Gonna Win It?"

s-titleize將字符串中的每個單詞s-titleize大寫，但這是對內置capitalize的簡單包裝，因此適用了Karl Voigtland的變通方法 。

ELISP> (s-titleize "Girl, you can't even think of calling this shit a war.")
"Girl, You Can'T Even Think Of Calling This Shit A War."
ELISP> (progn (modify-syntax-entry ?' "w") (s-titleize "Girl, you can't even think of calling this shit a war."))
"Girl, You Can't Even Think Of Calling This Shit A War."

該行為當然取決於所使用的語法表，即取決於主模式。 如果'字符具有"wp"語法，則它應該可以正常工作。 在文本模式下就是這種情況，但在大多數編程模式下並非如此。
