Linux: Compile C++ to WebAssembly and JavaScript using Emscripten and CMake

Download and Install Emscripten

• My preferred installation location is /home/user
• Get the latest sdk: git clone https://github.com/emscripten-core/emsdk.git
• Enter the cloned directory: cd emsdk
• Install the lastest sdk tools: ./emsdk install latest
• Activate the latest sdk tools: ./emsdk activate latest
• Activate path variables: source ./emsdk_env.sh
• Configure emsdk in your bash profile by running: echo 'source "/home/user/emsdk/emsdk_env.sh"' >> $HOME/.bash_profile

When resolving script imports, the code doesn't deals with empty string imports, and relies on nullptr :

https://github.com/adventuregamestudio/ags/blob/c52217180969576717173777d8ac195dd4347047/Engine/script/cc_instance.cpp#L1591

This works because when reading script objects, empty strings (a single \0 character) are replaced by a nullptr :

https://github.com/adventuregamestudio/ags/blob/c52217180969576717173777d8ac195dd4347047/Common/script/cc_script.cpp#L39

But when writing a script object, we don't treat the nullptr case, so if you read a script object, and want to write it back to a file, this will break here :

if(NOT CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT)
install(TARGETS ags
    DESTINATION "${CMAKE_INSTALL_PREFIX}/bin"
    )
endif()

#!/bin/bash
for file in *.mp4; 
do
    filename=$(basename -s .mp4 "$file")
    ffmpeg -i "${filename}.mp4" "${filename}.srt"
done
sed -i 's/<[^>]*>//g' *.srt

Building an AGS game

Ideally, while the project files holds the game information in the form that is the most convenient by the Editor used by the game developer, the game data represents this information in the most convenient form for the Engine.

Building a game is to transform information that describes the game to the form convenient for the Engine. This document describes how a platform agnostic AGS game is built.

A guide to writing a language grammar (TextMate) in Atom

Tree sitter

• Atom is transitioning to an entirely new way of defining grammars using tree-sitter. This will be enabled by default quite soon now. It is theoretically faster and more powerful than regex based grammars (the one described in this guide), but requires a steeper learning curve. My understanding is that regex based grammars will still be supported however (at least until version 2), so this guide can still be useful. To enable it yourself, go to Settings -> Core and check Use Tree Sitter Parsers

Links for tree-sitter help:

• tree-sitter: the main repo
• tree-sitter-cli: converts a JavaScript grammar to the required C/C++ files
• node-tree-sitter: module to use Tree-sitter parsers in NodeJS
• [My guide on starting a Tree-sitter grammar
