Code Difference Saved User Settings Tutorial
As a PHP programmer it is easy to admire …
- the server side file and database and operating system smarts of the great serverside language PHP is … all while …
- PHP writing out HTML (with its CSS and Javascript) has a web application able to access all that clientside intelligence
… and with this in mind, we allow for saved CSS styling user settings, as of today, with our Difference Report web application arrangements.
Don’t we need a database for this? Well, that is possible, and with serverside PHP, could be done, but we opt for clientside window.localStorage usage to …
- Save user CSS styling settings
- Recall user CSS styling settings
… so that a user might opt to “set and forget” their preferred set of …
- New additional
- Changed single line
- New block of lines
- Deleted lines
- Changed multiple lines
… (CSS Selector) sensitive “categories” of Difference Report data type settings.
As a result, building on yesterday’s Code Difference User Settings Tutorial, the deployment of CSS selector logic, in PHP, now changes to …

Yesterday’s Code Difference Colour Coding Tutorial Difference Report modifications (still) had the inherent weakness …

- we had not catered for busy traffic here … but, today …
- we cater, better, for busy online traffic … and at the same time …

It’s coming up to a few years now, since we looked at the code differences reporting we offer the reader, as a way to scrutinize code changes, around here, when we presented Code Download Table Difference Functional Hover Tutorial. Well, we thought we might try some colour coding to perhaps lift the fog on the cryptic nature of Linux diff (difference) command based reports. They can be cryptic because they can feed into the automation feeding of the report into other Linux commands to facilitate ongoing editing endeavours, but we do not want to go into that here, at least today.
But on examining the reports we came up with the following difference report “categories” if you will …
- New additional
- Changed single line
- New block of lines
- Deleted lines
- Changed multiple lines
… the header (of a block of interest) the dead give away, depending on the existence of “a” or “c” or “d” and/or “,” for a common sense reinterpretation by us not visiting “man diff” ourselves, yet, regarding this work.

Is it worth adding “onmouseover” event logic onto yesterday’s Code Download Table Difference Functional Linking Tutorial? You bet it is! Just because “onmouseover” has no relevance to mobile platforms, so, obversely, developing software with version control systems is irrelevant to mobile platforms.
… we figure. But this is of relevance to the programmer. Sometimes, rather than cater for all the platforms, settling on a subset (of those platforms) can be apt because …
- one of mobile or non-mobile subsets of platforms is irrelevant to the scenario … as for today … or …
- you try to reinvent the wheel on the pretext that you are waiting for a particular web browser or platform to allow the functionality in, into the future … you could be waiting a while, with the complexity of app arrangements going on around the net these days
Anyway, back to the “onmouseover” event on non-mobile platforms … it was the case that this event was a favourite for the conduit towards Ajax (client) functionality. And thinking on what we do today to nuance our Code Differences PHP web application, we were thinking …
What would Ajax (like to) do?
… and we decided Ajax would really like to …
- populate a “div” style=display:inline-block; element adjacent to the functional detail to inform about … but this was not possible … so, instead, we …
- populate a popup window near to the functional detail to inform about

Along the way we add some more hashtag navigations and set up more colour coding to the output of (the optional) “functional links” Code Difference reporting.

Download and Copy or Move Server Tutorial
Yesterday’s Download and Copy or Move Primer Tutorial was all about the “client side” of …
- the “server” side web applications/pages … and …
- a “client” side listener (like we talked about with Korn Shell listeners with Pandoc Document Conversion Email Tutorial)
… and we’ve just “tweaked” (albeit, very importantly, in our books (… but the pamphlettes are still not playing ball)) to ensure no “file clobbering” takes place so that the Korn Shell now does …
suf=""
isuf=-1
while [ -f "${dpath}/${brest}${suf}" ]; do
((isuf=isuf+1))
suf="_${isuf}"
done
if [ ! -z "$suf" ]; then
echo "mv ${dpath}/${brest} ${dpath}/${brest}${suf} # `date`" >> download_to_place.out
mv ${dpath}/${brest} ${dpath}/${brest}${suf} >> download_to_place.out 2>> download_to_place.err
fi
… in download_copier.ksh download_copier.ksh Korn Shell scripting on our macOS operating system “client”.
But today is mainly about filling in the missing bits on the “server” side. This (need for a) “conduit” we referred to yesterday is because we accept no folder paths can be mentioned at the “server” end. Suppose, though, that the “non-pathed” filename we supply to an “a” link’s “download” attribute can be prefixed by a mildly mashed up version of that path we copy to from the Downloads folder of your “client” computer or device, as you perform a “download” via the clicking of an “a” link.
Well, at this blog we’d already started functionality to toggle the use or not of …
- “a” links … with …
- “href” attribute containing “GETME” …
- but not “diff.php” … and …
- “download” attribute (the attribute necessary to “download” rather than our default displaying of source code in a new webpage)
Were you here, then, when we published WordPress Blog Download Mode Toggler Primer Tutorial (or were you indisposed again?!) There we established an “All Posts” menu “Toggle Download Mode from GETME” option piece of functionality to toggle between …
- displaying of source code in a new webpage for GETME “a” links … versus …
- use the changed PHP toggle_download.php in conjunction with a changed good ‘ol TwentyTen Theme header.php as below …

- the default download mode downloads to the Downloads folder without the GETME parts

Download and Copy or Move Primer Tutorial
Downloading from “the net” (“server land”) to your computer or device (“client land”) is a big part of the online experience and the sharing of data over the world wide web. But have you ever wondered about the two step design of …
- download from “the net” to a Downloads folder on your computer or device … and more often than not …
- you, the user, copies or renames this data to another location on your computer or device with command line or with operating system GUI
… ? Why not allow the “server” side define where it can download to on the “client”? Well, that would be a security nightmare, allowing a highjacking of mission critical files on your computer or device. So, I get it, that is a “no no”. But could we have a controlled “arrangement” between …
- the “server” side web applications/pages … and …
- a “client” side listener (like we talked about with Korn Shell listeners with Pandoc Document Conversion Email Tutorial)
… ? We think that sounds reasonable and so, today, we start our (two parts or more) mini-project (making step 2 above be considered to be programmatically handled, sometimes) designing a Korn Shell (“client” side) listener to suit our macOS “client” computer, executed as a background process via …
ksh download_copier.ksh &
But what is the conduit, if the “server” web applications/pages cannot define a destination folder other than the macOS Downloads folder for the user involved? Well, that is where we need either …
- Korn Shell interactive input (via read command) … or …
- additional argument … as per example …
ksh download_copier.ksh /Applications/MAMP/htdocs/ &
… if the folder to copy to is known ahead of time
… to define a “client land” folder to copy to (from the user’s Download folder (receiving the downloaded data).
That first Korn Shell read command interactive input was interesting to us for a command backgrounded via the “&” command suffix. But if stdin and stdout are not mentioned in the command you can answer this interactive input and then the processing the Korn Shell performs proceeds in the background. Exactly what we were hoping for, but weren’t sure that this was the case!
The picture is filled in better tomorrow as we discuss the conduit in more detail tomorrow.
