# Dockerfile
@ -43,6 +52,21 @@ Other Dockerfiles and scripts used to release the game:
The Docker container depends on all the git servers being up, but if you have
the uber blob source code you can read the Dockerfile to see what it does.
# Go Environment
Part of the build scripts involve building and running the `doodad` command
from this repo in order to generate the game's built-in doodads. For this to
work smoothly from your Linux or macOS build environment, you may need to
ensure that your `${GOPATH}/bin` directory is on your `$PATH` by, for example,
configuring this in your bash/zsh profile:
```bash
export GOPATH="${HOME}/go"
export PATH="${PATH}:${GOPATH}/bin"
```
For a complete example, see the "Build on macOS from scratch" section below.

## Build on macOS from scratch
Here are some detailed instructions how to build Sketchy Maze from a fresh
install of macOS Ventura that assumes no previous software or configuration
was applied to the system yet.
Install homebrew: https://brew.sh pay attention to the instructions at the end
of the install to set up your zsh profile for homebrew to work correctly.
Clone the doodle repository:
```bash
git clone https://git.kirsle.net/SketchyMaze/doodle
cd doodle
```
Note: on a fresh install, invoking the `git` command may cause macOS to install
developer tools and Xcode. After installed, run the git clone again to finish
cloning the repository.
Set your Go environment variables: edit your ~/.zprofile and ensure that $GOPATH
is configured and that your $PATH includes $GOPATH/bin. **Note:** restart your
terminal session or reload the config file (e.g. `. ~/.zprofile`) after making
this change.
```bash
# in your .zprofile, .bash_profile, .zshrc or similar shell config
export GOPATH="${HOME}/go"
export PATH="${PATH}:${GOPATH}/bin"
```
Run the bootstrap script:
```bash
python3 bootstrap.py
```
Answer N (default) when asked to clone dependency repos over ssh. The bootstrap
script will `brew install` any necessary dependencies (Go, SDL2, etc.) and clone
support repos for the game (doodads, levelpacks, assets).

* Run `make wasm` to build the WASM binary and `make wasm-serve` to run a simple

# Old Docs
# Build Tags
## Build Tags
Go build tags used by this game:
These aren't really used much anymore but documented here:
## dpp
### shareware
The dpp tag stands for Doodle++ and is used for official commercial builds of
the game. Doodle++ builds include additional code not found in the free & open
source release of the game engine.
> Files ending with `_free.go` are for the shareware release as opposed to
> `_paid.go` for the full version.
This build tag should be set automatically by the Makefile **if** the deps/
folder has a git clone of the dpp project. The bootstrap.py script will clone
the dpp repo **if** you use SSH to clone dependencies: so you will need SSH
credentials to the upstream git server. It basically means that third-party
users who download the open source release will not have the dpp dependency,
and will not build dpp copies of the game.
Builds the game in the free shareware release mode.
If you _do_ have the dpp dependency, you can force build (and run) FOSS
versions of the game via the Makefile commands `make build-free`,
`make run-free` or `make dist-free` which are counterparts to the main make
commands but which deliberately do not set the dpp build tag.
Run `make build-free` to build the shareware binary.
In source code, files ending with `_dpp.go` and `_foss.go` are conditionally
compiled depending on this build tag.
Shareware releases of the game have the following changes compared to the default
(release) mode:
How to tell whether your build of Sketchy Maze is Doodle++ include:
* No access to the Doodad Editor scene in-game (soft toggle)
### developer
> Files ending with `_developer.go` are for the developer build as opposed to
> `_release.go` for the public version.
Developer builds support extra features over the standard release version:
* Ability to write the JSON file format for Levels and Doodads.
Run `make build-debug` to build a developer version of the program.
* The version string on the title screen.
* FOSS builds (not dpp) will say "open source" in the version.
* DPP builds may say "shareware" if unregistered or just the version.
