Logging global variables

[MSV]

hi,

as part of swp, we are logging some information when ever we process a file.

we use below code for logging

<ui:group let:t1="{= smf:trace ('loading file {?filename} ')}"/>

now i would like to use global variable and print the same in the above trace message.

want to use ui:globalVarValue but not able to use it correctly.

can some one post an example for this ?

You'd want something like:

    smf:trace('loading file {?1}', ui:globalVarValue('filename'))

Depending on which version you are using, might be more convenient than smf:trace:

    <ui:log ui:info="loading file {= ?filename }"/>

    <ui:log ui:error="Error evaluating {= ui:globalVarValue('arg1') }"/>

I assume you have read https://uispin.org/ui.html#setGlobalVar which does show a small example?

Keep in mind that global variables only keep values for the duration of an SWP script. They will be stored in a dedicated tempGraph.
