@__FILE__ doesn't report current file in weaving context

[ssfrr]

when loading data it's often convenient to use @__FILE__ to reference files relative to the current file. During weaving that macro seems to evaluate to "none" though.

Additionally @__DIR__ is the current working directory path instead of the directory the file is located in.

Just for the record -- we'll need to wrap everything Weave evaluates in something like CodeTools.withpath.

Weave uses Core.eval in a SandBox module to evaluate expressions from the various formats after converting them into chunks.

Weave.jl/src/run.jl

Line 235 in 72e7ccf

obj = Core.eval(SandBox, expr)

We wouldn't be able to use CodeTools.withpath for this, right?

[aviatesk]

my hunch is adding something like this on eval_chunk will solve the problems.

I set this issue as a milestone for v0.11.

Yeah. Can also use something like https://github.com/JuliaDocs/DocumentationGenerator.jl/blob/d3c3ce4aa1dc9e3c813ac26d81023dda9d3dfc62/src/utils/rewrite.jl#L109-L117 if you don't want the dep on MacroTools.
