tarantool / try Goto Github PK

That is the reason why we use a custom delimiter in build-in tutorial. This make things more complex and I hope we can fix it.

Moved from tarantool/tarantool#619

tarantool> a = "&"

---
- error: '[string "a = ""]:1: unfinished string near ''<eof>'''

from the command line:

tarantool> a = "&"

---
...

tarantool> a

---
- '&'
...

Please add a buildslave to try.tarantool.org to rebuild container images on each change in https://github.com/tarantool/tarantool repository. A script to regenerate is already made (see tool.sh cron) and installed in /etc/cron.daily to automatically regenerate container image once a day. Please add buildslave and remove image generation from cron.

Please add docker, tarantool-1.6.3-240, tarantool-http-module as tarantool-try-module dependencies.

Please switch Dockerfile to official tarantool/tarantool:1.7 Docker images based on Alpine Linux.
We should eat our own dog food.

It is also worth mentioning that tarantool-try images are regenerated automatically by cron.
As result try.tarantool.org always has the latest version of Tarantool.

If the screen is full it does not scroll automatically and it is impossible to do so youself. Using try.tarantool.org

Motivation

We want to let the English-speaking part of the community to have used the Try Tarantool service. The current version of the frontend module can't fetch different files for different types of language.

We've already translated the tutorial and separated tutorial files into two subfolders: 'ru' and 'en'. See "/front/tutorial/en/" path.

What needs to do

• Support to show tutorial with user's browser language. As I understand we can fetch this data via JavaScript and change the language in realtime. If the user's language is missing by default show the tutorial in Russian.
• Add language selector for users who want to select the more appropriate language.

Preinstall http/shard/queue/expirationd rocks in try

Currently, the usage of "require" command is disabled on Try due to security issues. This ruins most examples from Tutorial, e.g.:

1. we cannot set custom delimiters and, subsequently, all multi-line examples in the Tutorial don't work (Ctrl+Enter for line breaks doesn't work on Try either, so there's no known work-around)
2. we cannot load sockets, etc
   Please enable the usage of "require".

Please move all JS requirements to our web server.

Like on https://godbolt.org or https://jsfiddle.net

Sometimes input spans multiple lines, ex: function declarations. There is a delimiter thing but it is less then convenient. Tarantool implemented delimiter-less parsing.

In try.tarantool.org a different method is used. Shift+Enter starts a new line without submitting the input. However the information about this feature is nowhere to be seen. The only way one can find about it is invoking console.delimiter(): in try the function prints a tip about Shift+Enter and does nothing besides that.

This is not reliable anymore, since normally console.delimiter() is unnecessary and no one is going to know about it.

It is especially useful feature of interactive console.

I see a lot of errors in the server log:

• Завести проект https://crowdin.com/project/try-tarantool
• Добавить конфиги в репозиторий
• Запушить в первый раз строки и переводы

Сначала нужно, чтобы в репозитории разделили файлы на ./en/ и ./ru/. Подробности тут https://www.notion.so/tarantool/e70da95c62484eb8a82f48aa7518c227

Конфиг будет выглядеть как-то так:

files:
  - source: /foo/en/*.md
    translation: /foo/ru/%file_name%.md

To make some people less mad, sandbox the container:
Add this:

os.execute = nil
os.exit = nil
os.rename = nil
os.tmpname = nil
os.remove = nil
io = nil
require = nil
package = nil

to:
https://github.com/tarantool/try/blob/master/try/container/container.lua

check that tutorial still works.

function is_prime(x) for i = 2,x-1 do if x % i == 0 then return false end end return true end
for i = 2,10000000 do if is_prime(i) then primes[i] = true end end
primes = {}
for i = 2,10000000 do if is_prime(i) then primes[i] = true end end

Error:
Attention! The server has stopped your tarantool machine. Please wait for restart or update the web page.

But this works:

a = {} for i = 2,10000000 do a[i] = true end

From my /etc/inputrc:

# map "page up" and "page down" to search history based on current cmdline
"\e[5~": history-search-backward
"\e[6~": history-search-forward

This is default on Gentoo and the feature I use very-very often to speed up my work. Don't know whether other distros have it enabled by default.

With latest site updates scroll for "try frame" was broken.
No scrollbar, mousewheel is useless

Apparently LuaJIT doesn't recognize the unicode character sent for space as a whitespace character.
Removing spaces around = sign fixes the problem.
