问题 What I'm trying to do is as follows: (let ((pj-path (concat src haxe-project-generator))) (when (file-exists-p pj-path) (shell-command (concat "env " (haxe-build-env-vars <more arguments>) (format "'%s'" pj-path))))) I.e.

问题 (+CMGL: 2,"REC READ","DD-Etopup",,"11/11/04,12:48:51+22" Hye! How's it going?) I want to store this sms message in python as a string. How can I do this? 回答1: Triple quotes - this will allow embedded single and double-quotes without escape characters. s = """(+CMGL: 2,"REC READ","DD-Etopup",,"11/11/04,12:48:51+22" Hye!

问题 I'm working in classical ASP and am trying to simply insert some user input into my MS SQL 2008 database. This is something I do basically every day, but I don't think I've ever experienced this bug before. The bug I am getting is that, if a user ends a line of text in backslash, and starts a new line below, both the backslash and line break are lost after the data is stored in the DB. If i try the following statement, hardcoded from an ASP file: UPDATE TBLarticle_text SET Introduction =

问题 I'm writing a Jinja macro to render some form data in a template, but for some reason the form data renders as escaped text instead of html!

问题 I have a vector of text strings containing smilies and a dictionary containing only the smilies. A <- c("This :/ :/ :) ^^","is :/ ^^", "weird^^ :)") B <- c(":)",":/","^^") I would like to extract all matches of smilies for each text string including duplicates, so my output should look like this: [[1]] [1] ":/" ":/" ":)" "^^" [[2]] [1] ":/" "^^" [[3]] [1] "^^" ":)" This is what I tried so far: # does not return duplicates sapply(A, function(x) B[str_detect(x, fixed(B))], USE.NAMES = FALSE) [
