# Developing Taskwarrior
The following describes the process for developing Taskwarrior. If you are only
changing TaskChampion (Rust code), you can simply treat it like any other Rust
project: modify the source under `taskchampion/` and use `cargo test` to run
the TaskChampion tests.
See the [TaskChampion CONTRIBUTING guide](../../../taskchampion/CONTRIBUTING.md) for more.
## Satisfy the Requirements:
* CMake 3.0 or later
* gcc 7.0 or later, clang 6.0 or later, or a compiler with full C++17 support
* libuuid (if not on macOS)
* python 3 (optional, for running the test suite)
* Rust 1.64.0 or higher (hint: use https://rustup.rs/ instead of using your system's package manager)
## Obtain and Build Code:
```
$ git clone --recursive https://github.com/GothenburgBitFactory/taskwarrior taskwarrior.git
$ cd taskwarrior.git
$ git checkout develop # Latest dev branch
$ git submodule init # This is now done by cmake as a test
$ git submodule update # Update the libhsared.git submodule
$ cmake -DCMAKE_BUILD_TYPE=debug . # debug or release. Default: neither
$ make VERBOSE=1 -j4 # Shows details, builds using 4 jobs
# Alternately 'export MAKEFLAGS=-j 4'
```
This will build several executables, but the one you want is probably `src/task`.
When you make changes, just run the last line again.
## Run the Test Suite:
First switch to the test directory:
```
$ cd test
```
Then you can run all tests, showing details, with
```
$ make VERBOSE=1
```
Alternately, run the tests with the details hidden in `all.log`:
```
$ ./run_all
```
Either way, you can get a summary of any test failures with:
```
$ ./problems
```
Note that any development should be performed using a git clone, and the current development branch.
The source tarballs do not reflect HEAD, and do not contain the test suite.
