Hello all,
I’m trying to do something a bit convoluted, because of how I need to architect things in my GURPS TW project (GURPS is a TTRP game for those who don’t know).
Context:
- Characters have skills. Certain skills can have a specialty, which could be anything. For example, the skill “Animal handling” has to be specialized in a species or type of animal. It could be anything, from Big cats to Unicorns, depending on the setting the game is happening in.
- The skills themselves (in this example, Animal Handling) are defined in the rules of the game, and are all individual tiddlers in my TW, tagged with
GURPS Skill. - All the skills a character knows are saved in a dictionary tiddler I called a “skillbook”.
- A character knows a skill to a certain level of mastery, with a minimum of 1.
- Skills are saved in the format
Skill name (specialty):level
What I’m trying to do:
When the Tiddler of a Character is edited, we obviously have access to all its characteristics, in order to edit them. The skillbook, appears like this in the character sheet tiddler being edited:
One can thus change the skillbook of a character via the drop down, or create a new one, or, edit it. When the “Edit skills” is pressed, the list of that character’s known skills appears in a table like this:
This table is populated by reading the character’s skillbook tiddler, like this (tried to indent it for easier viewing):
How populating the table is implemented
<table>
<tr><th></th><th>Skill</th><th>Difficulty</th><th>Relative skill</th><th>Effective skill</th><th><div class="mark" title="CP points"><span class="mark label entity clean"><span class="icon-cost-cp">'' points''</span></span></div></th></tr>
<$let skillbook={{!!skillbook}}>
<$list filter="[<skillbook>indexes[]]" variable="skill" emptyMessage="<tr><td colspan=11>No skills in skillbook.</td></tr>">
<$let pure-skill={{{ [<skill>split[ (]first[]] }}} specialty={{{ [<skill>split[ (]last[]] +[removesuffix[)]] }}}>
<tr><td>
<$button class="tc-btn-invisible tc-tiddlylink" tooltip="Remove skill">
<$action-setfield $tiddler=<<skillbook>> $index=<<skill>> />{{$:/core/images/delete-button}}</$button></td><td><$link to=<<pure-skill>>/> (<<specialty>>) <$macrocall $name=skillspec-edit skill=<<skillitem>> skillbook=<<skillbook>>/>

<$let advbook=<<advbook>> IQvalue={{{ [<cp>divide[20]trunc[]add[10]] }}}>
''<$text text={{{ [<rskill>add<IQvalue>] }}}/>''
</$let>
</$wikify>
</td>
<td align="center">
<$edit-text tiddler=<<skillbook>> index=<<skill>> type="number" min="1" default="1" size="2" tag=input/>
</td></tr>
</$let>
</$list>
</$let>
</table>
What I’m working on and can’t yet fully achieve is this: I’d like to have the specialization be editable when the “Edit spec” button is clicked, via a text-edit widget, like in the below image.
This is currently implemented via this (couple) procedure(s):
\procedure skillspec-edit-actions()
<$let skill-new={{{ [[ (]addprefix<pure-skill>addsuffix[<spellbook>get<skill>]] }}}>
<$action-setfield $tiddler=<<skillbook>> $index=<<skill-new>> $value=<<value>>/>
<$action-setfield $tiddler=<<skillbook>> $index=<<skill>>/>
</$let>
\end
\procedure skillspec-edit(skillbook, skill)
<$let pure-skill={{{ [<skill>split[ (]first[]] }}} specialty={{{ [<skill>split[ (]last[]] +[removesuffix[)]] }}} value={{{ [<skillbook>getindex<skill>] }}}>
<$reveal type="nomatch" state="$:/temp/skillspecedit" text="show" animate=yes><$button set="$:/temp/skillspecedit" setTo="show" actions="<action-setfield $tiddler=<<skillbook>> $field=<<skill>> $value=<<specialty>> />">Edit spec</$button></$reveal>
<$reveal type="match" state="$:/temp/skillspecedit" text="show" animate=yes><$edit-text tiddler=<<skillbook>> field=<<skill>> default=<<specialty>>/><$button set="$:/temp/skillspecedit" setTo="hide" actions="<<skillspec-edit-actions>>">{{$:/core/images/done-button}} Done editing</$button></$reveal>
</$let>
\end
The overarching mechanic being: I’m saving the current specialization in a field on the spellbook tiddler, the field is named with the full name and specialization of the skill so it is unique to each specialization. Then, when the field is edited via the text-edit widget, and the user clicks to validate the edition, I add the new index in the skillbook dictionary tiddler, and remove the old one.
The problem I have, is that I don’t know how to replace the old index (Animal handling (Big cats)) with the new (Animal handling (Small cats)). I’m guessing that I would have to actually delete the old index, and create the new one from scratch, but the way I wrote it above is probably completely wrong syntaxically.
Neither of the <action-setfield> widgets work; when I edit, the old skill index isn’t removed, and the new one isn’t added.
I’m sure <$let skill-new={{{ [[ (]addprefix<pure-skill>addsuffix[<spellbook>get<skill>]] }}}> is full of syntax errors, that for the life of me I can’t fix… but even if it was syntaxically correct, I don’t know why the action-setfield widgets don’t work at all…
You can take a look by following this link. Edit the “Character” tiddler to access the overall editing, then click on the “Edit skills” button.
Edit: It seems the first click on the button <$button set="$:/temp/skillspecedit" setTo="show" actions="<action-setfield $tiddler=<<skillbook>> $field=<<skill>> $value=<<specialty>> />">Edit spec</$button> doesn’t actually create and populate the field of the current skill (specialty). The field is created after editing the text-edit widget and clicking the second button <$button set="$:/temp/skillspecedit" setTo="hide" actions="<<skillspec-edit-actions>>">{{$:/core/images/done-button}} Done editing</$button>, though.
The core of the issue is certainly the <$let skill-new={{{ [[ (]addprefix<pure-skill>addsuffix[<spellbook>get<skill>]] }}}>. I changed the actions procedure to:
\procedure skillspec-edit-actions()
<$let skill-new={{{ [<pure-skill> <skillbook>get[<skill>] +[join[ (]] +[addsuffix[)]] }}}>
<$action-setfield $tiddler=<<skillbook>> $index=<<skill-new>> $value=<<value>>/>
</$let>
\end
… but now, when an edition happens, everything but the value of the first index is removed from the skillbook tiddler.
