combined multiple classes into one css rule

由 心已入冬 提交于 2019-11-28 04:21:58
问题 I'm trying to do some buckets here and generally I would do 1 class element at a time. That seems silly since classes can share attributes. HTML <div id = "outerBuckets"> <div class = "bucket1"> <div class ="bucketIcon"> <p></p> </div> </div> <div class = "bucket2"> <div class ="bucketIcon"> <p></p> </div> </div> <div class = "bucket3"> <div class ="bucketIcon"> <p></p> </div> </div> <div class = "bucket4"> <div class ="bucketIcon"> <p></p> </div> </div> <div class = "bucket5"> <div class =

How can I interpolate a variable into a Perl 6 regex?

由 谁都会走 提交于 2019-11-28 00:03:27
Synopsis 05 mentions that Perl 6 doesn't interpolate variables into a regex, but you can associate an external variable with a pattern. The docs don't mention this feature as far as I can tell. I think people are still going to want to build up a pattern from a string somehow, so I'm curious how that would work. Here's a program that demonstrates what happens now. I don't know if that's what is supposed to happen or what anyone intended. I insert a variable into a pattern. If you look at $r with .perl , you see the variable name. Then, I apply the pattern and it matches. I change the variable

Using the replace function in firestore security rules

由 社会主义新天地 提交于 2019-11-27 19:37:52
问题 I'm struggling with Firestore security rules. I want to check on a value that needs the replace function, i.e. an e-mail address. I can find some documentation in the general security docs, but that does not seem to work with Firestore. For example this works: allow write: if resource.data.members.data[(request.auth.token.email)] in ["admin"]; but this doesn't (and I changed the key in the members object accordingly): allow write: if resource.data.members.data[(request.auth.token.email

How to write files to current directory instead of bazel-out

由 大憨熊 提交于 2019-11-27 18:59:01
问题 I have the following directory structure: my_dir | --> src | | | --> foo.cc | --> BUILD | --> WORKSPACE | --> bazel-out/ (symlink) | | ... src/BUILD contains the following code: cc_binary( name = "foo", srcs = ["foo.cc"] ) The file foo.cc creates a file named bar.txt using the regular way with <fstream> utilities. However, when I invoke Bazel with bazel run //src:foo the file bar.txt is created and placed in bazel-out/darwin-fastbuild/bin/src/foo.runfiles/foo/bar.txt instead of my_dir/src/bar

What are the rules for function pointers and member function pointers to Standard functions?

由 狂风中的少年 提交于 2019-11-27 18:38:34
问题 What are the existing rules for taking function pointers or member function pointers to Standard functions? For example, something like auto p = &std::string::size; Is this legal? Would it be more or less legal if I explicitly requested the correct type, so it would function even if there was an additional implementation-added overload of std::string::size ? 回答1: Using the "correct" type doesn't make things better: Except for the virtual functions all functions in the standard C++ library can

Drools - Ability to define rules at runtime?

由 余生长醉 提交于 2019-11-27 12:11:50
It is possible to define rules dynamically completely at runtime ? Also change the ruleset at runtime. For example, at time = t_1 the ruleset is { R1, R2, R3 } at time = t_2 the ruleset is { R1, R3, R4 } ..... R1, R2 are rules that are defined at runtime. Thanks. Edson Tirelli Yes, Drools is completely dynamic. You can add/remove/replaces rules at runtime. All the existing sessions are automatically updated in order to keep consistency. Check the documentation/javadoc: http://www.jboss.org/drools/documentation And here you can see some integration tests: DynamicRulesTest.java Read the

List of C++ name resolution (and overloading) rules

由 醉酒当歌 提交于 2019-11-27 11:27:09
Where I can find a list of the rules that a C++ compliant compiler must apply in order to perform names resolution (including overloading)? I'd like something like a natural-language algorithm or flow chart. C++ standard of course has this set of rules but it is build up as new language statements are introduced and the result it's pretty hard to remember. To make a long story short, I'd like to know the complete and detailed answer to the question " What compiler do when it see the name 'A' ?" I know C++ is all " We do this when X but not Y if Z holds " so, I'm asking whether it is possible

Makefile with multiples rules sharing same recipe

由 孤人 提交于 2019-11-27 10:33:16
问题 I'd like to know if it's possible to write a Makefile with several rules, each one defining its own prerequisites and executing all of them the same recipe without duplicating the recipe. Example: TARGETS= file1 file2 file3 all: $(TARGETS) file1: dep1 dep2 file2: dep2 dep3 dep4 file3: dep2 dep1 cat $^ > $@ Thanks! 回答1: Yes, it is written in a rather obvious way: TARGETS= file1 file2 file3 all: $(TARGETS) file1: dep1 dep2 file2: dep2 dep3 dep4 file3: dep2 dep1 $(TARGETS): cat $^ > $@ UPD. Just

How to show all privileges from a user in oracle?

由 别说谁变了你拦得住时间么 提交于 2019-11-27 10:20:58
Can someone please tell me how to show all privileges/rules from a specific user in the sql-console? Teja You can try these below views. SELECT * FROM USER_SYS_PRIVS; SELECT * FROM USER_TAB_PRIVS; SELECT * FROM USER_ROLE_PRIVS; DBAs and other power users can find the privileges granted to other users with the DBA_ versions of these same views. They are covered in the documentation . Those views only show the privileges granted directly to the user. Finding all the privileges, including those granted indirectly through roles, requires more complicated recursive SQL statements: select * from dba
