git log - Is it possible to dynamically generate git log format? -


i'd show author name , author date, optionally show committer name , committer date if different author name , date.

this use after rebase. author info remains same, committer info changes. if , if different, i'd show committer info in addition author info.

author , committer info same:

%c(yellow)%h%creset %s %c(cyan)(%an - %ar)%creset

different:

%c(yellow)%h%creset %s %c(cyan)(%an - %ar, %cn - %cr)%creset

is possible?

there no conditionals in format arguments, , no format string expands conditionally that, so: no. on other hand, extract information commit manually (in script), compare, , choose format apply 1 commit, so: yes, if you're willing outside of git log command.

for showing single commit, latter seems reasonable. looking @ whole log, suspect painful. :-) (could still done, use git rev-list generate list of revs, git log each, 1 @ time, piping whole result through same pager git log use, etc. but... painful.)

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
