# Mage
Vikunja uses [Mage](https://magefile.org/) to script common development tasks and even releasing.
Mage is a pure go solution which allows for greater flexibility and things like better paralelization.
This document explains what taks are available and what they do.
{{< table_of_contents >}}
## Installation
To use mage, you'll need to install the mage cli.
To install it, run the following command:
```
go install github.com/magefile/mage
```
## Categories
There are multiple categories of subcommands in the magefile:
* `build`: Contains commands to build a single binary
* `check`: Contains commands to statically check the source code
* `release`: Contains commands to release Vikunja with everything that's required
* `test`: Contains commands to run all kinds of tests
* `misc`: Commands which do not belong in either of the other categories
## CI
These tasks are automatically run in our CI every time someone pushes to master or you update a pull request:
* `mage check:lint`
* `mage check:fmt`
* `mage check:ineffassign`
* `mage check:misspell`
* `mage check:goconst`
* `mage build:generate`
* `mage build:build`
## Build
### Build Vikunja
{{< highlight bash >}}
mage build:build
{{< /highlight >}}
Builds a `vikunja`-binary in the root directory of the repo for the platform it is run on.
### Statically compile all templates into the binary
{{< highlight bash >}}
mage build:generate
{{< /highlight >}}
This generates static code with all templates, meaning no template need to be referenced at runtime.
### clean
{{< highlight bash >}}
mage build:clean
{{< /highlight >}}
Cleans all build, executable and bindata files
## Check
All check sub-commands exit with a status code of 1 if the check fails.
Various code-checks are available:
* `mage check:all`: Runs fmt-check, lint, got-swag, misspell-check, ineffasign-check, gocyclo-check, static-check, gosec-check, goconst-check all in parallel
* `mage check:fmt`: Checks if the code is properly formatted with go fmt
* `mage check:go-sec`: Checks the source code for potential security issues by scanning the Go AST using the [gosec tool](https://github.com/securego/gosec)
* `mage check:goconst`: Checks for repeated strings that could be replaced by a constant using [goconst](https://github.com/jgautheron/goconst/)
* `mage check:gocyclo`: Checks for the cyclomatic complexity of the source code using [gocyclo](https://github.com/fzipp/gocyclo)
* `mage check:got-swag`: Checks if the swagger docs need to be re-generated from the code annotations
* `mage check:ineffassign`: Checks the source code for ineffectual assigns using [ineffassign](https://github.com/gordonklaus/ineffassign)
* `mage check:lint`: Runs golint on all packages
* `mage check:misspell`: Checks the source code for misspellings
* `mage check:static`: Statically analyzes the source code about a range of different problems using [staticcheck](https://staticcheck.io/docs/)
## Release
### Build Releases
{{< highlight bash >}}
mage release
{{< /highlight >}}
Builds binaries for all platforms and zips them with a copy of the `templates/` folder.
All built zip files are stored into `dist/zips/`. Binaries are stored in `dist/binaries/`,
binaries bundled with `templates` are stored in `dist/releases/`.
All cross-platform binaries built using this series of commands are built with the help of
[xgo](https://github.com/techknowlogick/xgo). The mage command will automatically install the
binary to be able to use it.
`mage release:release` is a shortcut to execute `mage release:dirs release:windows release:linux release:darwin release:copy release:check release:os-package release:zip`.
* `mage release:dirs` creates all directories needed
* `mage release:windows`/`release:linux`/`release:darwin` execute xgo to build for their respective platforms
* `mage release:copy` bundles binaries with a copy of the `LICENSE` and sample config files to then be zipped
* `mage release:check` creates sha256 checksums for each binary which will be included in the zip file
* `mage release:os-package` bundles a binary with the `sha256` checksum file, a sample `config.yml` and a copy of the license in a folder for each architecture
* `mage release:compress` compresses all build binaries with `upx` to save space
* `mage release:zip` paclages a zip file for the files created by `release:os-package`
### Build debian packages
{{< highlight bash >}}
mage release:deb
{{< /highlight >}}
Will build a `.deb` package into the current folder.
You need to have [fpm](https://fpm.readthedocs.io/en/latest/intro.html) installed to be able to do this.
### Make a debian repo
{{< highlight bash >}}
mage release:reprepro
{{< /highlight >}}
Takes an already built debian package and creates a debian repo structure around it.
Used to be run inside a [docker container](https://git.kolaente.de/konrad/reprepro-docker) in the CI process when releasing.
## Test
### unit
{{< highlight bash >}}
mage test:unit
{{< /highlight >}}
Runs all tests except integration tests.
### coverage
{{< highlight bash >}}
mage test:coverage
{{< /highlight >}}
Runs all tests except integration tests and generates a `coverage.html` file to inspect the code coverage.
### integration
{{< highlight bash >}}
mage test:integration
{{< /highlight >}}
Runs all integration tests.
## Misc
### Format the code
{{< highlight bash >}}
mage fmt
{{< /highlight >}}
Formats all source code using `go fmt`.
### Generate swagger definitions from code comments
{{< highlight bash >}}
mage do-the-swag
{{< /highlight >}}
Generates swagger definitions from the comment annotations in the code.
