|
This object is returned by [[environment]] and stores |
|
detailed information about how environment variables should be set |
|
during tests. It should be passed as the `env` keyword argument to |
|
tests and other functions. |
|
|
|
*Since 0.58.0* [[env.append]] and [[env.prepend]] can be called multiple times |
|
on the same `varname`. Earlier Meson versions would warn and only the last |
|
operation took effect. |
|
|
|
example: | |
|
```meson |
|
env = environment() |
|
|
|
# MY_PATH will be '0:1:2:3' |
|
env.set('MY_PATH', '1') |
|
env.append('MY_PATH', '2') |
|
env.append('MY_PATH', '3') |
|
env.prepend('MY_PATH', '0') |
|
``` |
|
|
|
methods: |
|
- name: append |
|
returns: void |
|
description: | |
|
appends the given values to |
|
the old value of the environment variable, e.g. `env.append('FOO', |
|
'BAR', 'BAZ', separator : ';')` produces `BOB;BAR;BAZ` if `FOO` had |
|
the value `BOB` and plain `BAR;BAZ` if the value was not defined. |

The separator to use. If not explicitly specified, the default path |

separator for the host operating system will be used, i.e. ';' for |
|
Windows and ':' for UNIX/POSIX systems. |

- name: prepend |
|
returns: void |

Sets the environment variable |
|
specified in the first argument to the values in the varargs |
|
joined by the separator. For instance, `env.set('FOO', 'BAR'),` sets envvar |
|
`FOO` to value `BAR`. |
