```

### Examples:

`yarn wsrun watch` will run `yarn watch` on every individual package, in parallel.

`yarn wsrun --stages build` will build all packages, in stages, starting from those that don't depend on other packages.

#### Specific packages:

`yarn wsrun -p planc -r watch` will watch planc and all of its dependencies.

`yarn wsrun -p planc -c watch` will watch planc only. Note that `-c` is passed here explicitly to
denote the beginning of the command. This is needed because `-p` can accept multiple packages. (`-c`
can also be substituted with `--` but that generates warnings in yarn)

`yarn wsrun -p 'app-*-frontend' -r watch` will watch all packages matching the glob
`'app-*-frontend'` and their dependencies. Globstar and extglobs are supported. Make sure to pass
the option quoted to prevent bash from trying to expand it!

`yarn wsrun -p h4zip planc -c test` - run tests for both `h4zip` and `planc

`yarn wsrun -p planc --exclude planc -r watch` will watch all of planc's dependencies but not planc

`yarn wsrun -p h4zip -r --stages build` will build all deps of h4zip, in order, then build h4zip

`yarn wsrun -p planc --stages --done-criteria='Compilation complete' -r watch` will watch planc deps,
in order, continuing when command outputs a line containing "Compilation complete"

`yarn wsrun --exclude-missing test` will run the test script only on packages that have it

`yarn wsrun --changedSince --exclude-missing test` will run the test script only on packages that have c
hanged since master branch and have `test` command

#### Additional arguments to scripts

If you want to pass additional arguments to the command you can do that by adding them after the
command:

`yarn wsrun -r --stages build -p tsconfig.alternative.json` - build all packages in stages with
and pass an alternative tsconfig to the build script

#### Commands not in the scripts field

When `--skip-missing` is not used, you can pass a command that doesn't exist in the scripts field:

`yarn wsrun -r --stages tsc -p tsconfig.alternative.json` - run tsc for all packages with an alternative tsconfig

#### Conditional execution

Conditional execution is supported with `--if` and `--ifDependency`

Examples

`yarn wsrun --stages --if build-needed build` - for each package it will first try `yarn wsrun build-needed` and only if the exit code is zero (success) it will run `yarn wsrun build`

`yarn wsrun --stages --if build-needed --ifDependency build` - it will run `build` for each package in stages, if either the package's own condition command was success, or any of the dependencies had a successful condition.
