问题 This question already has answers here : What is the difference between <%, <%=, <%# and -%> in ERB in Rails? (7 answers) Closed 5 years ago . I have been going through a crash course of Ruby and Ruby on Rails and i can't figure this out: In embedded ruby html files, there are several tags. <% %> for execution <%= %> for output, but what function do these tags serve: <%= -%>, what's with the "-" sign at the end ?

问题 I'm looking for a keyboard shortcut to select tags and all text between tags, such as: <div> Hello World </div> Consider above html code when I place cursor between div tags and press ctrl + shift + a it select all content that is Hello World but not div tags. 回答1: If you hit Ctrl Shift A once while your cursor is in the text, it will select all the text. Hit Ctrl Shift A again, and it will select the tags. Keep hitting it, and the selection will keep expanding outwards. 来源： https:/

问题 I have some history rewriting to do for which I'd like to keep my original tree intact for now. The rewritten tree should however copy the tags previously used as well. Is there any less manual option than e.g. prepending tag names with the branch name? 回答1: No, there is nothing like a per-branch tag in git. All branches and tags are just kinds of refs in Git; a ref is just a name that points to a particular revision in the revision history. For instance, if you have devel and master branches

问题 I'm using VSTS for CD/CI and I like to tag my builds (not the git branch) based on the git branch name. I got the below PowerShell script which is tagging the VSTS builds (it's different o git tag) : If ("$(Build.SourceBranchName)" -like "master") {Write-Host "##vso[build.addbuildtag]prod"} If ("$(Build.SourceBranchName)" -like "deploy/dev*") {Write-Host "##vso[build.addbuildtag]dev"} so when my code branch (git) is "master" then it's supposed to tag it "prod" which is does just fine. but

问题 I'm new to Perl and im trying to extract the text between all <li> </li> tags in a string and assign them into an array using regex or split/join. e.g. my $string = "<ul> <li>hello</li> <li>there</li> <li>everyone</li> </ul>"; So that this code... foreach $value(@array){ print "$value\n"; } ...results in this output: hello there everyone 回答1: Note: Do not use regular expressions to parse HTML. This first option is done using HTML::TreeBuilder, one of many HTML Parsers that is available to use

问题 The EventBrite API is great but there are a couple of really simple features that would make it much better. In particular, does anyone know a way to update the tags property of an event (or set it on a new event) - I can't see it on the API method http://developer.eventbrite.com/doc/events/event_update/ but'tags' is available in the response from get_event so am I just missing something. If this just hasn't been exposed through event_update yet it would be fantastic to get that implemented.
