Running kache

kache is a compiled program, download the one for your platform and extract the package to a directory you wish.

Go to that directory, open a command prompt and run the kache executable like

• ./kache if you are on linux or mac
• .\kache if you are on windows

This will start the application and port 7088 will be open by default.

Try to open telnet or netcat then

$: nc localhost 7088
ping

If you get the +PONG kache is working as expected.

Default configuration file can be found in config/kache-default.toml

kache can produce logs as you wish, in addition to default format it supports

• json
• logfmt

To run with a custom config file do

./kache --config=path/to/config/file.toml

Development

Prerequisites

• Go 1.10.+

Installing mage

mage is the build tool we use for build kache. To install mage

• Run go get -u github.com/magefile/mage
• For a proper installation refer official documentation

Setting up workspace

• Fork the repo
• Go to your GOPATH if you don't know about it learn from here
• Create a directory github.com/kasvith
• Clone the repo into that directory and cd to it

Make sure you have an active internet connection as for the first time it will download some depedencies.

Build the kache

• mage vendor will install all the dependencies of the project(will take some time)
• mage kache will produce the binary of the kache in bin directory
• mage kachecli will produce the binary of the kache-cli in bin directory

Other options

• mage check will run gofmt, goimports, go vet and all tests with 32 bit platform including
• mage fmt will run only gofmt on the code, will warn you when code has format errors
• mage vet will reports suspicious constructs
• mage imports will check import errors
• mage test will run a unit test with defaults
• mage test386 will run a test in 32-bit mode
• mage testrace will run a test with race conditions enabled
• mage -l for list all commands

Special note : According to your environment executable will be built, for windows users it will need to add .exe to the end of -o flag like go build -o bin/kache.exe ./cmd/kache
