EXEC command examples do not work. Should use var instead of const

[koresar]

I have just found out that if I use +++! const a=1;+++ command does not work. Throws Unknown symbol 'a'.

But as soon as I changed it to +++! var a=1;+++ the further usage of the a variable works.

Is it a known thing?

+++! const a=1;+++ works on my machine, at least within the installed docx-templates repo and from the example-node directory. What Node version are you using? I've tried with v8.11.4, v9.11.2, v10.12.0 and v11.1.0 and it consistently works.

Same for me : I cannot reproduce it on my side.
@koresar could you give a full example to reproduce your problem ?

@guigrpa Koresar is right, if you declare your variables as const in +++EXEC +++ you will be able to use them only in the exec script. If you want to access these variables in other +++EXEC +++ scripts or +++INS +++ you have to declare them more globally with var.

+++! const a=1;+++ is working but useless as you will never be able to access a in any other snippet.

To resume:

+++! const a='1';+++
+++= a+++

does not work

+++! var a='1';+++
+++= a+++

works

@razyon I see! Thanks for the clarification. I guess the original post was missing the key part: "from another EXEC block".

#48 has just been merged explaining this in the docs. It's normal that variables declared with const are not visible, since they are local to the block in which they're defined. Use var instead, or just nothing at all: +++! a = '1'.

Apologies for the misleading issue description.
