- path.exists() is no longer part of nodejs
- fs.exists() is deprecated (as of nodejs >= 8)
- checking a file for existence before using it is open to raca condition. It is
preferable to go ahead and use the file, and eventually handle the error
- we can afford two simple synchronous fs operations here
This commit vastly shortens (and simplifies) the version table within
handler/APIHandler.js by building each version's entry incrementally based off
the previous version.
The resulting table has been validated by comparing the "before" and "after"
output of the following loop on both versions of the code (albeit with an
intermediate "sort" step to account for the different insertion order)
for (let v in version) {
let m = version[v];
for (let [k, a] of Object.entries(m)) {
console.log(v, k, a);
}
}
The patch also fixes a few typos, and removes a duplicate definition of
getChatHistory which in each applicable version was defined with two different
parameter lists, but where only the second would be used.
Get rid of an else branch to simplify code layout. No functional changes at all.
==============
This series is an attempt to reduce the control structure depth of the code
base, maintaining at the same time its exact same behaviour, bugs included. It
is, in a sense, an initial attempt at a refactoring in the spirit of its
original definition [0].
The idea beyond this refactoring is that reducing the code depth and, sometimes,
inverting some conditions, bugs and logic errors may become easier to spot, and
the code easier to read.
When looked at ignoring whitespace changes, all of these diffs should appear
trivial.

skinName must be a single string (no directory separators in it) pointing to an
existing directory under /src/static/skins.
In case these conditions are not met, its value is rewritten to "no-skin".
Also, the value of skinName if sent to the client via clientVars for allowing
its use it in the browser.
* Add scroll when it edits a line out of viewport
By default, when there is an edition of a line, which is out of the
viewport, Etherpad scrolls the minimum necessary to make this line
visible. This makes that the line stays either on the top or the bottom
of the viewport. With this commit, we add a setting to make possible to
scroll to a position x% pixels from the viewport. Besides of that, we
add a setting to make an animation of this scroll.
If nothing is changed on settings.json the Etherpad default behavior is
kept
Users still cannot choose which shortcuts they want to enable/disable,
so it does not make sense (yet) to have a cookie with that preference.
This can be reverted once we create an UI to change shortcuts, but
PLEASE PLEASE PLEASE do not read the cookie every time handleKeyEvent is
called!!!
This is an adjustment to #2891.
On some erros that display a modal with "Force reconnect" button, allow
Etherpad to automatically reload pad after a few seconds. Amount of
seconds is defined on settings.json.
Still need to create tests for this feature, and implement i18n.
Currently pressing ENTER on a line that ends with ':', '[', '(' or '{'
automaticaly indents the new line with 4 spaces. The variable added by
this commit to settings.json allow an Etherpad instance to not have this
behavior.
