# To figure out what should be precompiled, run this script, then move
|
|
# precompile_Plots.jl in precompiles_path (see below) to src/precompile.jl
|
|
|
|
# This script works by using SnoopCompile to log compilations that take place
|
|
# while running the examples on the GR backend. So SnoopCompile must be
|
|
# installed, and StatsPlots, RDatasets, and FileIO are also required for
|
|
# certain examples.
|
|
|
|
# If precompilation fails with an UndefVarError for a module, probably what is
|
|
# happening is that the module appears in the precompile statements, but is
|
|
# only visible to one of Plots' dependencies, and not Plots itself. Adding the
|
|
# module to the blacklist below will remove these precompile statements.
|
|
|
|
# Anonymous functions may appear in precompile statements as functions with
|
|
# hashes in their name. Those of the form "#something##kw" have to do with
|
|
# compiling functions with keyword arguments, and are named reproducibly, so
|
|
# can be kept. Others generally will not work. Currently, SnoopCompile includes
|
|
# some anonymous functions that not reproducible, but SnoopCompile PR #30
|
|
# (which looks about to be merged) will ensure that anonymous functions are
|
|
# actually defined before attempting to precompile them. Alternatively, we can
|
|
# keep only the keyword argument related anonymous functions by changing the
|
|
# regex that SnoopCompile uses to detect anonymous functions to
|
|
# r"#{1,2}[^\"#]+#{1,2}\d+" (see anonrex in SnoopCompile.jl). To exclude all
|
|
# precompile statements involving anonymous functions, "#" can also be added to
|
|
# the blacklist below.
