equivalent of get() for a string ?

[Marc Chantreux]

hello people,

I would like this

if exists('g:purescript_update_path')
if g:purescript_update_path
call PurescriptUpdatePath()
endif
endif

To be something like

if get('g:purescript_update_path',v:false)
call PurescriptUpdatePath()
endif

but get() doesn't work with strings and i don't find something close.
did i miss something from the doc ?

regards,
marc

Shameless plug: my GetVar script (https://www.vim.org/scripts/script.php?script_id=353) does this.

thanks for noticing but i can't add such a dependency as i'm trying to
fix an existing package and would like to push my code upstream at
some point.

Marc,

try this here:

if get(g:, 'purescript_update_path')
call PurescriptUpdatePath()
endif

You can omit the v:false in get(), see `:help get()` for more details.
g:, w: and b: return the global, window-local, and buffer-local dictionary,
respectively. See `:help g:` for more details. For example, if you run `:echo g:`
in the command-line it will print all the global variables as a dictionary. When
we pass g:, b: or w: to get(), we essentially use the following overload:
get({dict}, {key} [, {default}])
