Kartik K. Agaram e5b5a82970 a sharp edge in Lua's dorequire()
You can't call it on a file that isn't a module, i.e. that doesn't
return something at the end. Use dofile() instead.

Kartik K. Agaram 394c9f894c fix a few sample apps
Broken since Mar 18, when I started running tests in src/file.lua.

It's more than a little ugly that .lua files in src/ require helpers
inside .tlv apps.

Kartik K. Agaram dad78ac424 new perm: files under dir specified at commandline
I think we can now use a file browser app with relative safety. Just
give it inargs permissions, and provide a top-level directory at the
commandline to gain access to everything under it.

Kartik K. Agaram 6099fa7fb2 experiment: ask for permission on file operations
I'm not quite sure how to think about asking for permissions with
respect to my red/orange/green color codes. On the one hand, it seems
safer than many alternatives. On the other hand, it's liable to lead to
fatigue and blindly allowing apps to do stuff. For now I consider ask to
be orange. Ask + network allowed = red in summary, though it's orange on
the permissions screen since there's more space to convey nuance. Then
again, nobody may heed the nuance. The summary up top on the permissions
screen is definitely still a work in progress. And there's a
chicken-and-egg problem here: I can't really get a good feel for
real-world bugs in the permissions screen until _other programmers_ are
building apps to use the permissions screen, but they're almost certain
to have a crappy time of it.

I considered introducing a primitive called ask() in the Lua
interpreter, but it doesn't really make sense to validate it and so on.
I'm also not really supporting mixing Ask with other features so far.

This is a major step towards turning my permissions screen into
spaghetti; monitoring closely.

Kartik K. Agaram 5b64c4b3bc show common suggestions when editing permissions
Computer owners shouldn't get in the habit of trusting app authors
regarding permissions. But they have to trust somebody, and they already
trust the Teliva platform if they are running it.

Kartik K. Agaram b5aca9a571 toot-toot: stop clobbering existing files
I've been reluctant to do this until now because it makes it more
difficult to grant an app the ideal permissions. Here's what I use:

  return string.find(filename, 'toot') == 1

But I'm also trying to keep people from looking to the app to figure out
what permissions to give it :/

Kartik K. Agaram 3618487289 toot-toot: disable ctrl-k
Rather than invest LoC in asking for confirmation or an undo feature,
just have people restart to clear the page.

I fucking suck for how many ways I can come up with to lose data in a
text editor. It really should have been fucking obvious that clearing
the page so easily was a footgun just waiting to happen.

Kartik K. Agaram b56590ddc9 some more reorg of the standard library
Now life.tlv and gemini.tlv are also minimizing how much of the standard
library they pull in, just to be easy to read.

Kartik K. Agaram 9ec94aa982 disallow all relative paths (./ or ../)
Teliva's model doesn't include any way to change directory. We just have
relative paths and absolute paths. Relative paths should not be able to
reach into parent directories.

The current test is a bit hacky; it also disallows directories ending in
a period. Hopefully not an issue.

Kartik K. Agaram fddbe08fc8 graphviz: for basic stats, show all nodes ordered
The ordering is topological; nodes come before their dependencies.

Also some more helpful functions in the template for new apps.

Kartik K. Agaram a05f713dc1 graphviz: tweak data structure slightly
A node's edges contain an associative array of target nodes rather than
a linear array.

This way we automatically dedup edges when we load multiple graphs.

Kartik K. Agaram 0374e82aa5 show current definition being edited
This serves two purposes:
- Things get confusing if function being defined doesn't match the
  definition name. Displaying the current definition helps diagnose this
- We're already able to see callers at a glance even if the cursor is
  below the fold. The name of the current definition is arguably more
  important in that situation.

Kartik K. Agaram 5380817ce6 function names from globals rather than debug info
This reclaims all the slowdown in sieve.tlv, and it also is now smart
enough to detect calls to global bindings that pass through variables.

On the flip side, we lose names for non-globals. But that's not very
useful anyway in Teliva's context.

This is still not enough to detect callers through coroutines
(intervening anonymous functions), though.

src/ldo.c now has a minimal diff with Lua 5.1.

It might be a bit slower than it was before, but not noticeably so..

This approach doesn't support indirect calls.
