Modified Files:
js_internal.c
Log Message:
Add js.exec().
This allows executing a new script in a specified scope, much like load(). There are important differences however...
1) js.exec() *must* specify a scope.
2) js.exec()d scripts can call exit() and their handlers are ran then,
rather than when the parent script exists as in js.load().
3) The js object is installed in the scope with the real JS object as the
prototype. This generally shouldn't be an issue, but if you're doing
strange things, stranger things may happen.
4) As part of #3, the exec_path/exec_dir/exec_file/startup_dir/scope
properties of the JS object represent the new script, not the calling
one.
5) js.exec() only searches in the passed startup dir (if specified) and the
current js.exec_dir path. It does not search the load paths or the mods
directory at all.

This API is also subject to change.

A child of the parent scopes js object can't do on_exit() stuff properly
due to the missing private context. Create a new JS object in the child instead.

We also need to copy in the js.load_path_list array contents since we don't want the child changing the parent by accident.

Just curious... what would it take to get Synchronet up to the current spidermonkey engine?

Related to your recent arguments change for `js.exec()`, having a spread operator would help for when writing such scripts.

A lot of work.

js.exec(...params)

We don't have the spread operator currently, but reading about it brought me to function.apply() which looks like that can be used to solve the js.exec() problem I had. I don't need to array argument trick. Thanks for the tip!

js_internal.c
Log Message:
Revert the last commit (mostly): don't treat array arguments to js.exec() specially, just pass them on to the script as-is. Included a JSDOC note about the use of js.exec.apply() to pass a variable number of arguments (ala execv).

Thanks Tracker1 for the pointer to 'spread' which led me to function.apply() and the JS-standard method of achieving the result I needed with this enhancement.

I still think that a script that calls exit() is unlikely to expect non-string arguments in the first place, but if we don't need special case behavior, it's better not to add it and keep the behavior consistent with load() and require(). That was the decision of the executive board anyway. :-|

Fix js.exec() returned nul" unless exit() was called explicitly

Don't use the "exit_code" property value as the return value of js.exec() unless it's a number. As reported by mlong (thanks).

Also, "exit_code" was being set to null (instead of void/undefined) in js_PrepareToExecute(). I think this was just an oversight or typo by Deuce from his commit of 5 years ago (f3256d81). Since we're comparing exit_code with JSVAL_VOID in other places to determine if it was actually set, this appears to be a long standing bug.

If the search up the scope tree for js.exec_dir fails, the script 'path' would be left blank leading to a weird error message.
e.g. !JavaScript default.js line 249: Error: Script file () does not exist

I just did an update and rebuilt my Synchronet binaries (and updated my default.js as well). That seems to fix the issue we were seeing with DDMsgReader and default.js. But now I'm seeing the same error in a different situation.

In my command shell (custom JS), I have this command to run my file area chooser:

bbs.exec("?../xtrn/DigDist/AreaChoosers/DDFileAreaChooser.js");

That works. However, I also have a JS script in my sbbs/mods directory that I use as a test sandbox to try out new things, which I usually run from my main menu. I tried using the same line above in my test script to run my DDFileAreaChooser.js, but when I run that, I get the error:

!JavaScript DigitalDistortionTest.js line 8: Error: Script file () does not exist

It seems this might be a recent issue, as I've done similar things in my sandbox test script, and I don't remember seeing this before.

It was something silly on my part.. I had a line above it using js.exec(), and I thought I had removed that but it was still in there.

Also, I had to check out a fresh copy of the repo in order to rebuild successfully. In the copy of the repo I had, it was getting a build error ('no rule to make target' for something, but I don't remember what it was now). But it's building now, and all is good.
