thisProcess.interpretCmdLine could set nowExecutingPath with Document.current.path

... and the error printout becomes useless for troubleshooting. I'm not sure we want to make that a general situation.

big complication:

when the code in a file loads other code in other files.

this is really common in Instr and in various players.

there would have to be a messy call stack.

Not messy at all. Just save the old path in the method and restore it at cleanup, like Environment:use does.

executeFile { arg pathName ... args;

var result, saveExecutingPath = thisProcess.nowExecutingPath;

if (File.exists(pathName).not) { ["file \"",pathName,"\" does not exist."].join.postln; ^nil };

thisProcess.nowExecutingPath = pathName;

protect { result = this.compileFile(pathName).valueArray(args) }

{ thisProcess.nowExecutingPath = saveExecutingPath };

^result

}

(That's a change from what I committed before... um, not just "change"... improvement :)

and it has benefits for other code elsewhere

Yes... I'm using it in chucklib so that all the preloaded objects know where they were defined.
