ifSplice :: Monad m => Bool -> Splice mSource
Run the splice contents if given condition is True, make splice disappear if not.
paramSplice :: MonadSnap m => Splice mSource
Gets the value of a request parameter. Example use:
utilSplices :: [(Text, SnapletISplice b)]Source
A list of splices offered in this module
addUtilSplices :: HasHeist b => Initializer b v ()Source
Bind splices offered in this module in your Initializer
:: Monad m | |
=> Text | A name for the select element |
-> Text | An id for the select element |
-> [(Text, Text)] | value, shown text pairs |
-> Maybe Text | Default value |
-> Splice m |
Splice helper for when you're rendering a select element
runTextAreas :: Monad m => HeistState m -> HeistState mSource
Assume text are contains the name of a splice as Text.
This is helpful when you pass a default value to digestive-functors by putting the name of a splice as the value of a textarea tag.
heistLocal runTextAreas $ render "joo/index"
:: MonadIO m | |
=> FilePath | Path to the directory on disk holding the javascript files. |
-> String | A prefix to add to the src attribute of each script tag. |
-> m [Node] |
Searches a directory on disk and all its subdirectories for all files with names that don't begin with an underscore and end with a .js extension. It then returns script tags for each of these files.
You can use this function to create a splice:
("staticscripts", scriptsSplice "static/js" "/")
Then when you use the <staticscripts/>
tag in your templates, it will
automatically include all the javascript code in the static/js
directory.
ifFlagSplice :: SnapletISplice bSource
Check to see if the boolean flag named by the ref attribute is present and set to true in snaplet user config file. If so, run what's inside this splice, if not, simply omit that part.
Example:
<flag ref="beta-functions-enabled"> stuff... </flag>
This will look for an entry inside your .cfg file:
beta-functions-enabled = true
