The proposed fix in #11662 was effectively a workaround for some
already bad logic. What we actually want to do is described in the
updated function comment (from the spec in #5914), and requires an
additionl case that was not present in the original implementation
(which effectively assumed a collapsed message was condensible).
Also add some documentation.
Fixes#11662.
This is totally broken on master. If you "collapse" a /me
message, it adds the "More..." link without actually
hiding any content.
I have another branch related to collapse/condense that
will make this easier to resurrect.
This commit prepares the frontend code to be consumed by webpack.
It is a hack: In theory, modules should be declaring and importing the
modules they depend on and the globals they expose directly.
However, that requires significant per-module work, which we don't
really want to block moving our toolchain to webpack on.
So we expose the modules by setting window.varName = varName; as
needed in the js files.
We now initialize most modules in ui_init.js, which
isn't the perfect place to do it, but at least now
we have a mostly consolidated entry point.
All the new foo.initialize() methods introduced in
this module run the same order relative to each
other as before this commit. (I did some console
logging with a hacked version of the program to
get the order right.) They happen a bit later than
before, though.
A couple modules still have the `$(function() {`
idiom for miscellaneous reasons:
archive - is a different bundle
common - used elsewhere
list_render - non-standard code style
scroll_bar - no exports
setup - probably special?
socket - $(function () is nested!
transmit - coupled to socket
translations - i18n is a bigger problem
ui_init - this bootstraps everything
We now make direct calls to `send_flags_update` for
seting collapsed/uncollapsed, rather than going through
the `batched_updaters` mechanism.
Also the methods in `message_flags` to set
collapsed/uncollapsed now take a single message.
This fixes the mobile web experience for Chrome on iOS.
Apparently, Chrome-on-iOS silently has a `viewport` module that
overrides and user-defined module by that name, causing all of our
code that accesses the viewport module to not work on that platform.
We fix this by renaming it.
Using the offsetHeight getter is ~2.5x faster than
getBoundingClientRect() on what can be an expensive operation to do in
the hundreds of times.
Note: Tim thinks that this may have been different a few years ago,
since we tested fairly carefully before settling on
getBoundingClientRect, but benchmarks pretty clearly show offsetHeight
is faster today, so we should use that.
First user-fasing problem is that when user click to "Collapse" button
of message from narrowed list, buttons "Uncollapse" and "[More...]" does
not work. Second, is that when user collapse/uncollapse some message
from narrowed list, the collapsing/uncollapsing of the same message in
home list does not work in appropriate way.
In "popovers.js" there is the function that is called on click to the
buttons "Collapse" or "Un-collapse". It should show and hide body of a
message. If a message list is narrowed, it should show/hide message in
home list too. So, the first problem is that "toggle_row()" in this
function call methods "collapse(row)" or "uncollapse(row)" from
"condense.js" twice (for row and home_row) using condition
"if (message.collapsed)". When it happen the first time, the variable
"message.collapsed" is changed. That is why next call of "toggle_row()"
work incorrectly.
The second problem is that the function in "condense.js" that is
called on click to the button "[More...]" contains no code for
collapsing/uncollapsing message from home list. It just calls
"collapse(row)" or "uncollapse(row)" for row from narrowed list.
Now, functions "collapse(row)" and "uncollapse(row)" get row from
current list and change both messages (from current list and home
list). On-click functions call them just once for making all of needed
message changes. So, when user collapse or uncollapse message from
home or narrowed list it works correctly.
