Add items to a running tiddler

[anarchoNerd]

Is there a plugin that will allow me to place some code before an item or a list of items that will append the text to an already existing tiddler? As an example, I am currently taking a YouTube course on the Linux command line and am creating a tiddler for each video. One of my note headers is "Commands learned", and I would like to have this list of commands placed into a tiddler of the same name without having to manually add them.

No plugin needed, much can be done just with wikitext, typically with a button to trigger the activity.

My I suggest you not get too hung up on appending text to a tiddler, when additional tiddlers can be associated with the parent tiddler, see new here button, or streams etc... appending can be done later with a button, just set the text field of a tiddler to the text field + the new text. 

Perhaps you can describe your desired workflow a little more.

Hi Tones,

Thank you for your reply. 

Here is an example of what my Commands learned header looks like right now:

Commands learned:

• whoami - Prints current username.
• clear (ctrl l) - Clears terminal.
• adduser - *requires sudo* Adds new user.
• which - Prints directory which command binaries are being used from. 

The list goes on, but I think you can gather the idea from this. As of now, they are just living inside of the tiddlers in which they were recorded. I would like to automatically add each one to a separate tiddler (and auto sort them if possible) so that all commands can be accessed in one place, while also remaining in their original tiddler.

I have also created a Glossary tiddler for recording important definitions. For that, I have simply been using this format [[new term|Glossary]] as a link to the Glossary tiddler and then adding them manually there. I think this is what you are referring to in your reply, but I'm not certain. If so, this doesn't really solve the problem of having to manually add them to the tiddler.

I would like to automatically add each one to a separate tiddler (and auto sort them if possible) so that all commands can be accessed in one place, while also remaining in their original tiddler.

Try this:

1) First, create a tiddler (e.g., "CommandListMacros") tagged with $:/tags/Macro, containing this macro definition:

\define addToList(tid)

<$vars lf="

">

<$button class="tc-btn-invisible" style="text-align:left;" actions="""

   <$set name="lines" filter="[[$tid$]get[text]splitregexp[\n]]">

      <$action-setfield $tiddler="$tid$" text={{{ [enlist<lines>sort[]join<lf>] }}} />

   </$set>""">

!!$tid$:

<<commands>>

<$action-setfield $tiddler="$tid$" text={{{ [{$tid$!!text}addsuffix<lf>addsuffix<commands>] }}}/>

</$button>

</$vars>

\end

2) Then, create a tiddler containing the following content:

\define commands()

* ''whoami'' - Prints current username.

* ''clear (ctrl l)'' - Clears terminal.

* ''adduser'' - *requires sudo* Adds new user.

* ''which'' - Prints directory which command binaries are being used from. 

\end

<<addToList "Commands Learned">>

Notes:

In the macro tiddler:

* The addToList() macro presents a $button that shows the title of the target tiddler as a heading, followed by the list of commands

* $vars lf="..." defines a literal newline character

* Note that the blank line before the "!!$tid$" is necessary so that the heading is rendered properly using "block mode"

* The primary $action-setfield appends the commands to the text of the target tiddler, separated from existing content by a newline

* After adding the commands to the target tiddler, the $button then invokes the actions="""...""" as a secondary action

* This secondary action reads the contents of the now updated target tiddler, splitting them into separate lines

* It then enlists and sorts those lines, joins them back together, and writes it back to the target tiddler

* Note that the enlist<lines> filter operator removes any duplicate lines, so it won't matter if you click the addToList button multiple times

In the content tiddler:

* First, define the list of commands as a local macro named "commands"

* Then, invoke the <<addToList>> macro to display that command list with the $button surrounding it

* When you click on the displayed command list (or the heading), the commands are added to the target tiddler and sorted into place.  Q.E.D.

Let me know how it goes...

enjoy,

That's awesome, thank you. I only have a very very basic understanding of javascript and want to learn, so I'm going to try and understand this as I implement it, so it may be a bit. I'll let you know once I get it up and running. Unfortunately both my son and I were exposed to covid over the weekend and we're waiting on test results, so I'm off work and have some extra time. I'll start looking at it tonight and may have it figured out by tomorrow.

The code that Eric posted is TiddlyWiki wikitext only. So JavaScript is working in the background to convert wikitext inth HTML.

Here are a links to the wikitext elements Eric used.

I hope you both are well. Good luck!

Best of luck with the covid-19, 

In Australia if you get a test because you were a close or casual contact with Covid you have to self isolate until you get the result (24-48 hours max). Ee would not be allowed (with some special exceptions) to go to work today. Be carful.

Today I proudly got my second Astra-Zeneca after apparently the ideal 12 weeks and I hope to get a booster from an RNA vaccine in the next 6-12 months

Then perhaps we can visit France again, and isolate at home on our return, if necessary.

It is a curse to say "may you live in interesting times".
