Overview ¶
Package exec defines tasks for running commands.
These are the supported tasks:
// Run executes the given shell command. Run: { $id: *"tool/exec.Run" | "exec" // exec for backwards compatibility // cmd is the command to run. cmd: string | [string, ...string] // dir specifies the working directory of the command. // The default is the current working directory. dir?: string // env defines the environment variables to use for this system. // If the value is a list, the entries mus be of the form key=value, // where the last value takes precendence in the case of multiple // occurrances of the same key. env: [string]: string | [...=~"="] // stdout captures the output from stdout if it is of type bytes or string. // The default value of null indicates it is redirected to the stdout of the // current process. stdout: *null | string | bytes // stderr is like stdout, but for errors. stderr: *null | string | bytes // stdin specifies the input for the process. If stdin is null, the stdin // of the current process is redirected to this command (the default). // If it is of typ bytes or string, that input will be used instead. stdin: *null | string | bytes // success is set to true when the process terminates with a zero exit // code or false otherwise. The user can explicitly specify the value // force a fatal error if the desired success code is not reached. success: bool // mustSucceed indicates whether a command must succeed, in which case success==false results in a fatal error. // This option is enabled by default, but may be disabled to control what is done when a command execution fails. mustSucceed: bool | *true }
