extra blocks for variables

[fridolinux]

We have this situation:

1. A block, that reports all variables.
   

   
   
   and
   
   
   
   You could use this block for example like this, so the output needs to be ringed:
   

2. A block, that says, if a variable is visible or not.
   

3. A block that reports the value of a variable.
   (It should be similar to this: )

Block 3 can be written like so, unless there's something different going on with the "value of variable" block.

Blocks 1 and 2 could possibly be implemented using that Javascript function reporter but I don't know any Javascript.

this is actually something I want to do, and that last block has already been made, I can't remember who made it, but here it is.

and here's the xml

<blocks app="Snap! 5.4, http://snap.berkeley.edu" version="1"><block-definition s="variable %&apos;var&apos;" type="reporter" category="variables"><header></header><code></code><translations></translations><inputs><input type="%s"><options>§_getVarNamesDict</options></input></inputs><script><block s="doIf"><custom-block s="does variable %s exist?"><block var="var"/></custom-block><script><block s="doReport"><block s="evaluate"><block s="reportJSFunction"><list><l>v</l></list><l>return this.variables.getVar(v)</l></block><list><block var="var"/></list></block></block></script></block><block s="doRun"><block s="reportJSFunction"><list><l>v</l></list><l>throw new ReferenceError(`Variable ${v} does not exist.`)</l></block><list><block var="var"/></list></block></script></block-definition></blocks>

the <does variable exist?> block is in the create variables in program library

I tried this, but it only worked, when you put a variable in a ring, not with a block that reports a ringed variable.

[fridolinux]

Thanks! This is very useful!

[ego-lay_atman-bay]

did you do this?

because if you want it to report the value of the variable, you should unringify the block, so it should look like this

[snapenilk]

Do you have a variable and a variable reporter both named variable?

[ego-lay_atman-bay]

oh, um, yeah, here's everything but with the custom block named var
