Move rust.gni and deno.gni into build_extra/ Removes rust_library which was only an action. This instead defines rust_component, which is an action plus a gn "component" target to expose the resulting object file. This simplifies link code in rust.gni. Support rust modules that can be linked into C++. |

deno
A secure TypeScript runtime built on V8
-
Supports TypeScript 2.8 out of the box. Uses V8 6.8.275.3. That is, it's very modern JavaScript.
-
No
package.json. No npm. Not explicitly compatible with Node. -
Imports reference source code URLs only.
import { test } from "https://unpkg.com/deno_testing@0.0.5/testing.ts" import { log } from "./util.ts"Remote code is fetched and cached on first execution, and never updated until the code is run with the
--reloadflag. (So, this will still work on an airplane. See~/.deno/srcfor details on the cache.) -
File system and network access can be controlled in order to run sandboxed code. Defaults to read-only file system access and no network access. Access between V8 (unprivileged) and Golang (privileged) is only done via serialized messages defined in this protobuf. This makes it easy to audit. To enable write access explicitly use
--allow-writeand--allow-netfor network access. -
Single executable:
> ls -lh deno -rwxrwxr-x 1 ryan ryan 55M May 28 23:46 deno > ldd deno linux-vdso.so.1 => (0x00007ffc6797a000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f104fa47000) libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f104f6c5000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f104f3bc000) libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f104f1a6000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f104eddc000) /lib64/ld-linux-x86-64.so.2 (0x00007f104fc64000) -
Always dies on uncaught errors.
-
Supports top-level
await. -
Aims to be browser compatible.
Status
Segfaulty. Check back soon.
Roadmap is here.

Github Noise
I am excited about all the interest in this project. However, do understand that this is very much a non-functional prototype. There's a huge amount of heavy lifting to do. Unless you are participating in that, please maintain radio silence on github. This includes submitting trivial PRs (like improving README build instructions).
Compile instructions
Get Depot Tools and make sure it's in your path.
You need yarn installed.
You need rust installed.
You need ccache installed.
Fetch the third party dependencies.
./tools/build_third_party.py
Generate ninja files.
gn gen out/Debug --args='cc_wrapper="ccache" is_debug=true '
Then build with ninja (will take a while to complete):
ninja -C out/Debug/ deno
Other useful commands:
gn args out/Debug/ --list # List build args
gn args out/Debug/ # Modify args in $EDITOR
gn desc out/Debug/ :deno
