@@ -770,10 +770,16 @@ The values for `g:ale_fixers` can be a list of |String|, |Funcref|, or
|lambda| values. String values must either name a function, or a short name
for a function set in the ALE fixer registry.
Each function for fixing errors must accept two arguments `(buffer, lines)`,
representing the buffer being fixed and the lines to fix. The functions must
return either `0`, for changing nothing, a |List| for new lines to set, or a
|Dictionary| for describing a command to be run in the background.
Each function for fixing errors must accept either one argument `(buffer)` or
two arguments `(buffer, lines)`, representing the buffer being fixed and the
lines to fix. The functions must return either `0`, for changing nothing, a
|List| for new lines to set, or a |Dictionary| for describing a command to be
run in the background.
Functions receiving a variable number of arguments will not receive the second
argument `lines`. Functions should name two arguments if the `lines` argument
is desired. This is required to avoid unnecessary copying of the lines of
the buffers being checked.
When a |Dictionary| is returned for an |ALEFix| callback, the following keys
are supported for running the commands.
