History.js vs. window.history for HTML5-only mode -


does history.js offer substantial advantages on html5's window.history nowadays? we're not interested in supporting/falling html4 hashbang urls.

history.js doesn't support anchors in pushstate(), while window.history does. need feature if there no big reasons use history.js instead of native window.history in html5-only mode, we'd rather go latter.

yes - on website say:

provide cross-compatible experience html5 browsers (they implement html5 >history api little bit differently causing different behaviours , bugs - >history.js fixes ensuring experience expected / same / great throughout >the html5 browsers)

those differences small, , googling wasn't enough find them - had in source code - seems main 1 fixing html5 functionality in safari. there 2 problems safari implementation - 1 history.back fails return hash state set location.hash susequently replaced history.replacestate.

the second when busy safari fail apply state changes.

relevant history.js source code:

    history.bugs = {         /**          * safari 5 , safari ios 4 fail return correct state once hash replaced `replacestate` call          * https://bugs.webkit.org/show_bug.cgi?id=56249          */         sethash: boolean(!history.emulated.pushstate && navigator.vendor === 'apple computer, inc.' && /applewebkit\/5([0-2]|3[0-3])/.test(navigator.useragent)),          /**          * safari 5 , safari ios 4 fail apply state change under busy conditions          * https://bugs.webkit.org/show_bug.cgi?id=42940          */         safaripoll: boolean(!history.emulated.pushstate && navigator.vendor === 'apple computer, inc.' && /applewebkit\/5([0-2]|3[0-3])/.test(navigator.useragent)),

so guess decision comes down whether care safari 5 , safari ios 4.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

javascript - Clean way to programmatically use CSS transitions from JS? -

as title implies, there proper way set initial css properties (or class) , tell browser transition these value? for example ( fiddle ): var el = document.queryselector('div'), st = el.style; st.opacity = 0; st.transition = 'opacity 2s'; st.opacity = 1; this not animate opacity of element in chrome 29/firefox 23. because ( source ): [...] you’ll find if apply both sets of properties, 1 after other, browser tries optimize property changes, ignoring initial properties , preventing transition. behind scenes, browsers batch property changes before painting which, while speeding rendering, can have adverse affects. the solution force redraw between applying 2 sets of properties. simple method of doing accessing dom element’s offsetheight property [...] in fact, hack work in current chrome/firefox versions. updated code ( fiddle - click run after opening fiddle run animation again): var el = document.queryselector('div'...
