This commit includes updates that affects the build, testing, and
deployment of Tile38.
- The root level build.sh has been broken up into multiple scripts
and placed in the "scripts" directory.
- The vendor directory has been updated to follow the Go modules
rules, thus `make` should work on isolated environments. Also
some vendored packages may have been updated to a later
version, if needed.
- The Makefile has been updated to allow for making single
binaries such as `make tile38-server`. There is some scaffolding
during the build process, so from now on all binaries should be
made using make. For example, to run a development version of
the tile38-cli binary, do this:
make tile38-cli && ./tile38-cli
not this:
go run cmd/tile38-cli/main.go
- Travis.CI docker push script has been updated to address a
change to Docker's JSON repo meta output, which in turn fixes
a bug where new Tile38 versions were not being properly pushed
to Docker

=====
|
|
|
|
Liner is a command line editor with history. It was inspired by linenoise;
|
|
everything Unix-like is a VT100 (or is trying very hard to be). If your
|
|
terminal is not pretending to be a VT100, change it. Liner also support
|
|
Windows.
|
|
|
|
Liner is released under the X11 license (which is similar to the new BSD
|
|
license).
