Moving Files That Have Dependencies

Today I had to SCP(move/copy) Maestro's HTML file over to my EC2 Instance (my AWS Private Webserver) and it turned out that his html file had dependencies and was not stand alone.  Because of these dependencies, when I SCP'd the file over, it didn't work on my webserver.

What is stand alone? Stand alone means that a program/code is able to be moved from location to location and will still work.  It is not dependent on another program/code in order to run correctly.

What is a dependency?  A dependency is when a program/code is dependent on another program/code.  For example, if you have an HMTL file that contains images, if you move that HTML file to another location but do not move the image files, then when you try to run that HTML file through a web browser, the images will not render.

I found out that I couldn't just SCP Maestro's HTML file into the root directory of my EC2 Instance because of the file's existing two dependencies.  Those dependencies (files) had specific directories that I needed to create in my EC2 Instance first.

In order to create those directories, I needed to issue the "mkdir" command (make directory) in my EC2 Instance.  If you look at the picture to the left, you will see the first directory I needed to create is called "collegium".  I  issued a "cd  /var/www/html" command (change directory to my docroot).  From there, I started to make my new directories.

<---  See Picture to the left:

The first directory I made was called "collegium". I did this with the "mkdir collegium" command.  Then I issued a "cd collegium" command (change directory into collegium).  I had to do this because the next directory that needed to be made had to be located in the "collegium" directory.  Once in the "collegium" directory, I issued another "mkdir" command, but this time calling the next one "grammar".  So it looked like this:  "mkdir grammar".  Then I "cd grammar", and then once inside "grammar", I "mkdir client".  Then I "cd client".  Once inside "client", I "mkdir utils".  Then I "cd utils".  Once inside "utils", I was able to "mkdir recorderjs".  Once I finished creating all of the directories in my EC2 Instance, THEN  I was able to SCP the two dependency files over to the correct directories.

After doing this and refreshing my browser, the program was working fairly well.  The dependencies for Maestro's HTML file were satisfied.

I finally was able to make the round trip (meaning that I started with an image, I created XML files based off of the image,  I now have the program customized for my EC2 instance (webserver) that reads the XML I created, and it renders that same image that I started out with .  👊

If you would like to view Maestro's HTML file that I SCP'd into my EC2 Instance that has those 2 dependencies:

The BEFORE Image (where I took the information from to markup in XML)



For the FINISHED product, click the link and follow the directions below it:

The AFTER Image (the end result after marking up the information in XML)

Now click the "ok" button.  To the left you will see "Select User Name".  Click that and scroll down to select "lisa".  For "Choose Unit", select "unit 15".  For "Start Frame #", put a "2" in the box.  You will now be able to view a sample of what the Artes Latinae project is and what I have been working on with Maestro!

XPATH and XPATH Expressions In XMLLINT

XPATH And XPATH Expressions Earlier, I told you about xmllint and xmllint for html files .  Let's say you just want to parse the <span> tags within your html file or just your <span lang="el"> tags? Enter:  Xpath. Xpath is yet another option available within the xmllint language. Remember, an Xpath is used to navigate through elements and attributes in xml and html documents.  Xpath uses Xpath Expressions to select nodes or node sets within a document. Example 1 .  Looking for all of the <span> tags within an html document. xmllint -- html -- xpath " // span" StedmanLesson10.html xmllint = This tells the command line that we are going to be using the xmllint language. space = because we always have space in between commands -- = Remember, these are the two hyphen-minus characters that we need to tell the command line that we are going to use an xmllint option. html = This is the xmllint option we want to

Back To The Basics

Click photo above to see photo clearly  It's Been A LOOONG Minute since I have coded!!   Even so, I decided to give JavaScript another try.  I always seem to do good and then when I get to this one area, I always seem to hit a brick wall.  Well....nothing like getting back up and trying again right?   I decided to try Rithm School's online JavaScript Fundamentals FREE course .  I have never joined their school but their free courses tend to explain things in a way my brain understands it.  💁 To let you know how much I have forgotten in the coding world, I couldn't even remember how to write the basic commands for an HTML document! Yesterday I started the fundamentals free course and I am so glad that I did.  Because of time, I only made it through the JavaScript History and Setup chapter, but that chapter was enough to get my memory flowing again!   It started to feel familiar and I quickly remembered why I enjoyed coding so much.  Yesterday and this morning, I just erased

SCP: Secure Copy Protocol

SCP = Secure Copy Protocol.  What is it and why is it important?   SCP provides a secure way to transfer files from one computer to another. For the project that I'm working on, I needed to SCP (send a copy) the XML files, as well as the image files, from my computer to my EC2 Instance (my web server).  Once done,  my teacher was be able to view my work via my website. Here are the steps to do this: 1.  Open two command windows (the program for my computer is called Terminal). 2.  Let's say the file I want to send is called "SallysFirstDate.xml" and it is located in the "tomy" folder.  Here is where that file lives: /Documents/path/tomy/SallysFirstDate.xml I need to first issue the command to "change directory"(cd) through each folder until I reach the folder that my file is located in.   It would look like this: cd /Documents THEN I need to "cd" again into the "path" folder: cd path THEN I need to "c
