Why is the hyphen conventional in symbol names in LISP?

由 ＊爱你＆永不变心＊ 提交于 2019-12-09 10:20:09
问题 What's the reason of this recommendation? Why not keeping consistent with other programming languages which use underscore instead? 回答1: I think that LISP uses the hyphen for two reasons: "history" and "because you can". History LISP is an old language, and in the early days typing an underscore could be challenging. For example, the first terminal I used for LISP was an ASR-33 teletype. On some hosts and teletype models, the key sequence for the underscore character would be interpreted as a

R How do i keep punctuation with TermDocumentMatrix()

由 落花浮王杯 提交于 2019-12-08 02:58:36
问题 I have a large dataframe where I am identifying patterns in strings and then extracting them. I have provided a small subset to illustrate my task. I am generating my patterns by creating a TermDocumentMatrix with multiple words. I use these patterns with stri_extract and str_replace from stringi and stringr packages to search within the 'punct_prob' dataframe. My problem is that I need to keep punctuation in tact within the 'punct_prob$description' to maintain the literal meanings within

Bad line breaking in Eclipse javadoc comments

由 雨燕双飞 提交于 2019-12-07 08:40:46
问题 There's a minor but annoying bug, I think, in the Eclipse built-in Java formatter. I have a Javadoc comment that looks like this: /** * - - - stuff - - - {@code mTasksBelow}. */ where period at the end is in column 81. The formatter is set to wrap Javadoc comments at line 80. Unfortunately, when I format the code, it does this: /** * - - - stuff - - - {@code mTasksBelow} * . */ This puts white space between the text and the period in the generated output, so a browser rendering the Javadoc in

This regex to strip punctuation also incorrectly makes the word Báenou into Benou

由 家住魔仙堡 提交于 2019-12-06 04:14:31
问题 The goal of this regex is to remove punctuation characters: var myTxt = "Welcome, Visitor: The Royal Kingdom Of Báenou"; myTxt = myTxt.replace(/[^a-zA-Z0-9 ]+/g, '').replace('/ {2,}/',' '); alert(myTxt); So the text above should become this: Welcome Visitor The Royal Kingdom Of Báenou But instead it incorrectly drops the á in Báenou to produce this: Welcome Visitor The Royal Kingdom Of Benou What's the simplest change I could make to the regex to make it work as intended? 回答1: Your problem is

What is '`' character called?

由 [亡魂溺海] 提交于 2019-12-05 09:59:27
问题 I feel silly for asking this but it isn't like I could google this. What is the ` character called? In case it doesnt show up, it is the character used for inline code with markdown. Also, on most keyboards, it shares the key with ~ . I like all three answers so I made this a CW instead of accepting 回答1: All sorts of things, but in programming mostly the back-quote or backtick, 回答2: Grave (pronounced Grahv, not like the synonym for tomb) or Grave accent . 回答3: From the Jargon file, the prime

Strip all punctuation from a string in VB.net

由 北战南征 提交于 2019-12-05 04:35:54
问题 How do I strip all punctuation from a string in vb.net? I really do not want to do stringname.Replace("$", "") for every single bit of punctuation, though it would work. How do i do this quickly and efficiently? Other than coding something that codes this for me.... 回答1: You can use a regular expression to match anything that you want to remove: str = Regex.Replace(str, "[^A-Za-z]+", String.Empty); [^...] is a negative set that matches any character that is not in the set. You can just put

tm custom removePunctuation except hashtag

由 北城以北 提交于 2019-12-05 00:47:50
问题 I have a Corpus of tweets from twitter. I clean this corpus (removeWords, tolower, delete URls) and finally also want to remove punctuation. Here is my code: tweetCorpus <- tm_map(tweetCorpus, removePunctuation, preserve_intra_word_dashes = TRUE) The problem now is, that by doing so I also loose the hashtag (#). Is there a way to remove punctuation with tm_map but remain the hashtag? 回答1: You could adapt the existing removePunctuation to suit your needs. For example removeMostPunctuation<-

Redefining “sentence” in Emacs? (single space between sentences, but ignoring abbreviations)

由 谁说我不能喝 提交于 2019-12-04 16:26:41
问题 I would like to be able to navigate by sentence in Emacs (M-a, M-e). Here's the problem: by default, Emacs expects that each sentence is separated by two spaces, and I'm used to just putting a single space. Of course, that setting can be turned off, to allow for sentences separated by only a single space, like so: (setq sentence-end-double-space nil) But then Emacs thinks that a sentence has ended after abbreviations with a full stop ("."), e.g. after something like "...a weird command, e.g.
