Hello, this library sounds really useful. I am trying it out but get the following error
mapbox-filter: Parsing mapbox style failed: Error in $.layers[1]: Unknown function name / wrong param count: in CallStack (from HasCallStack): error, called at app/Main.hs:224:20 in main:Main
I think it might be caused by this part in the second layer in my style layers (at index 1 of layers):
"filter": [ "all", [ "in", "class", "residential", "suburb", "neighbourhood" ] ],
I understand not all expressions are supported. Is the 'in' not supported yet?
Thanks!
Dear buddy!
I get several errors for paint
attributes. paint['fill-opacity']
, line-width
, fill-translate
and etc. do they affect the shrink process? I'd appreciate if you add support for them (even with simply ignoring them if they aren't effective in the process)
Thanks a lot
Hi buddy!
I have the following filter in my style but I get Comparing unequal things: Fix (UApp "get" (Fix (UStr "subclass"))), Fix (UStr "glacier"): Anyvs. String
error.
"filter": [
"==",
[
"get",
"subclass"
],
"glacier"
],
the same problem exists with !=
expression.
First of all, thanks for creating and sharing this tool @ondrap :)
I use a style which has a in
filter.
This seems not supported right now.
It would be awesome if you could add this, or tell me how to workaround it.
An example is below. It will currently produce Parsing mapbox style failed: Error in $.layers[X]: Unknown function name / wrong param count: in
"filter": [
"all",
[
"in",
"building",
"cathedral",
"chapel",
"church",
"mosque",
"temple",
"synagogue",
"shrine",
"civic",
"hospital",
"school",
"stadium",
"train_station",
"transportation",
"university"
]
]
Another example:
"filter": [
"all",
[
"in",
"highway",
"primary",
"trunk"
],
[
"==",
"tunnel",
"yes"
]
]
Dear Ondrej,
I have some filters with to-number
expression as follows:
"filter": [
"all",
[
"==",
[
"to-number",
[
"get",
"admin_level"
]
],
2
],
[
"!=",
[
"to-number",
[
"get",
"maritime"
]
],
1
],
[
"!=",
[
"to-number",
[
"get",
"disputed"
]
],
1
]
],
I'll be so thankful if you add support for it too. ^_^ ๐
Many editors of Mapbox Styles do not care about a difference between number and string for the filters.
So in many style.json there is the following in the filter expression
["==", "layer", 2]
When running filter on such a style one received the error Parsing mapbox style failed: Error in $.layers[X]: Comparing unequal things: Fix (UStr "layer"), Fix (UNum 2.0): Stringvs. Number
As far as I know the styles the number should always be treated as a string here.
It would be amazing to see this being supported.
Hi dear,
I'd appreciate if you add match
expression support.
I use openmaptile styles which has in
and !in
filter statements. I saw that filters
are depricated. So, I changed it to match
expression but unfortunately it's not supported in your app yet.
Thank you!
According to the style spec the source is required except for the background layer (which is nothing but a plain color mostly).
Example:
{
"id": "background",
"type": "background",
"layout": {
"visibility": "visible"
},
"paint": {
"background-color": "rgba(235, 237, 215, 1)"
}
}
Currently it will error with Parsing mapbox style failed: Error in $.layers[X]: key "source" not present
