| 01:54 | < Yossarian> | http://linuxgizmos.com/movidius-ai-acceleration-technology-comes-to-a-mini-pcie-card/ eh? |
| 01:54 | < catalyst> | http://bash.org/?400459 |
| 02:51 | < Yossarian> | am I going nuts? In lua's repl, isn't there a shortcut for typing print statements or io.write? |
| 02:55 | <&ToxicFrog> | In recent luas you can just type an expression and it'll print the result of evaluating |
| 02:55 | <&ToxicFrog> | In older ones prefix the line with = as a shortcut for return, e.g. `= 1+1` => `return 1+1` and will output 2 |
| 03:01 | < Yossarian> | I am thinking # is an operator to print or return sizeof for some reason |
| 03:09 | <@celticminstrel> | It's a REPL after all. |
| 03:09 | <@celticminstrel> | So you'll always see the result of whatever expression you type in. |
| 03:09 | <@celticminstrel> | No need to overthink it. |
| 03:09 | <@celticminstrel> | Just type 1+1 and you'll see 2 |
| 03:10 | <@celticminstrel> | # is an operator that returns the number of array elements in a table |
| 03:19 | < SmithKurosaki> | I really need to get back into coding and learn SQl |
| 03:44 | < Yossarian> | I saw a feature in Juypter Notebook or whatever it is called for interpreted language (python) that as you write you have chunks of code, you can seperate chunks and type in there and it will execute that given chunk or selected code as if it were in the REPL. |
| 03:44 | < Yossarian> | Can emacs do that? |
| 03:45 | < Yossarian> | because in some instances a lot of testing to be done, especially if it is an interpreted language... if I can get real-time feedback by running certain chunks by typing into a block or being able to execute a block... |
| 03:47 | < Yossarian> | I was just curious if emacs can do that, besides with emacslisp. |
| 03:47 | < Yossarian> | I can make my editor do something like what I described. |
| 03:49 | < Yossarian> | another interesting thought is I know lua's garbage collector has "chunks" and I'm not sure often it sweeps away chunks but it'd be interesting to have them stick around, I know lua is implemented as a stack machine buttt I think something like that could be done. |

| 16:34 | <&ToxicFrog> | I believe emacs can do that if you are willing to spend enough time fiddling with elisp. |
| 16:34 | <&ToxicFrog> | Yossarian: ^, also # is a unary prefix operator named __len that returns the size of the array-part of tables and the length (in bytes) of strings, and can be customized for userdata. |
| 16:35 | <&ToxicFrog> | Yossarian: I have no idea what you mean by "lua's garbage collector has chunks [...] ot |
| 16:35 | <&ToxicFrog> | it'd be interesting to have them stick around", anything that gets collected is, definitionally, no longer accessible except with a C-side debugger |
| 16:35 | <&ToxicFrog> | (and if you're doing that you can also just turn off the collector entirely) |
| 16:36 | <&ToxicFrog> | Also, Lua is not a stack machine, it's a register machine with a sliding register window that looks stack-y to the C API. |
| 16:39 | <&ToxicFrog> | celticminstrel: you did in fact need some overthinking in earlier versions of lua, because lua has a statement/expression distinction and the repl only accepted statements, not expressions |
| 16:39 | <&ToxicFrog> | So 'return 1+1' emits 2, but '1+1' is a syntax error. |
| 16:39 | <&ToxicFrog> | This is definitely fixed from 5.3 onwards, I don't think it's fixed in luajit. |
