slangroom-exec

The missing slangroom executor. We are working the .wasm transpile of the slangroom, but in the meantime this repo could be used similar to the zencode-exec to embed https://dyne.org/slangroom into other languages.

slangroom-exec is a simple utility that reads from STDIN the following content

1. conf
2. slangroom-contract
3. data
4. keys
5. extra
6. context

separated each per new-line and encoded in base64 and outputs the slangroom execution to stoud.

💾 Install

wget https://github.com/dyne/slangroom-exec/releases/latest/download/slangroom-exec-$(uname)-$(uname -m) -O ~/.local/bin/slangroom-exec && chmod +x ~/.local/bin/slangroom-exec

check that works by running:

wget -O - https://raw.githubusercontent.com/dyne/slangroom-exec/main/test/fixtures/welcome.slex| slangroom-exec

Demo

SLangroom-EXec Format Encoder

This script is used to encode the format of the slangroom-exec command into a string that can be used in the slangroom-exec command.

The script accepts the six parameters that are used in the slangroom-exec command and encodes them into a string. The encoded string is then printed to stdout.

Usage

For each of the parameters, the script also has option flags:

-c or --conf for conf
-s or --slangroom-contract for slangroom-contract
-d or --data for data
-k or --keys for keys
-e or --extra for extra
-x or --context for context
-F or --filename lookup files based on a prefix
-h or --help to print the help message

The named convention -F option flag

When you have a suite of files if you follow the formal slangroom name convention as such:

conf: `${prefix}.conf`
slangroom-contract: `${prefix}.slang`
data: `${prefix}.data.json`
keys: `${prefix}.keys.json`
extra: `${prefix}.extra.json`
context: `${prefix}.context`

you can just run:

slangroom-exec -F prefix

STDIN

if you just pass something in /dev/stdin is interpreted as the contract. This also overwrites the --slangroom-contract option flag if passed as a duplicate.

Examples

To encode a slangroom-contract, you can run:

cat slangroom-contract.slang | slexfe

To encode parameters from a file, you can run:

slexfe -s slangroom-contract.slang

To load data and keys

slexfe -s slangroom-contract.slang  -d slangroom-contract.data.keys -k slangroom-contract.keys.json

To load many files with a correct naming convention

slexfe -F prefix
