returns: file |

description: | |
|
This function can run in three modes depending on the keyword arguments |
|
passed to it. |
|
|
|
When a [[@cfg_data]] object is passed |
|
to the `configuration:` keyword argument, it takes a template file as |
|
the `input:` (optional) and produces the `output:` (required) by |
|
substituting values from the configuration data as detailed in [the |
|
configuration file documentation](Configuration.md). *(since 0.49.0)* |
|
A dictionary can be passed instead of a |
|
[[@cfg_data]] object. |
|
|
|
When a list of strings is passed to the `command:` keyword argument, |
|
it takes any source or configured file as the `input:` and assumes |
|
that the `output:` is produced when the specified command is run. |
|
|
|
*(since 0.47.0)* When the `copy:` keyword argument is set to `true`, |
|
this function will copy the file provided in `input:` to a file in the |
|
build directory with the name `output:` in the current directory. |
|
|
|
kwargs: |
|
capture: |
|
type: bool |
|
since: 0.41.0 |
|
default: false |
|
description: | |
|
When this argument is set to true, |
|
Meson captures `stdout` of the `command` and writes it to the target |
|
file specified as `output`. |
|
|
|
command: |
|
type: list[str | file] |
|
description: | |
|
As explained above, if specified, Meson does not create |
|
the file itself but rather runs the specified command, which allows |
|
you to do fully custom file generation. *(since 0.52.0)* The command can contain |
|
file objects and more than one file can be passed to the `input` keyword |
|
argument, see [[custom_target]] for details about string |
|
substitutions. |
|
|
|
copy: |
|
type: bool |
|
default: false |
|
since: 0.47.0 |
|
description: | |
|
As explained above, if specified Meson only |
|
copies the file from input to output. |
|
|
|
depfile: |
|
type: str |
|
since: 0.52.0 |
|
description: | |
|
A dependency file that the command can write listing |
|
all the additional files this target depends on. A change |
|
in any one of these files triggers a reconfiguration. |
|
|
|
format: |
|
type: str |
|
since: 0.46.0 |
|
default: "'meson'" |
|
description: | |
|
The format of defines. It defaults to `'meson'`, and so substitutes |
|
`#mesondefine` statements and variables surrounded by `@` characters, you can also use `'cmake'` |
|
to replace `#cmakedefine` statements and variables with the `${variable}` syntax. Finally you can use |
|
`'cmake@'` in which case substitutions will apply on `#cmakedefine` statements and variables with |
|
the `@variable@` syntax. |
|
|
|
input: |
|
type: str | file |
|
description: | |
|
The input file name. If it's not specified in configuration |
|
mode, all the variables in the `configuration:` object (see above) |
|
are written to the `output:` file. |
|
|
|
install: |
|
type: bool |
|
default: false |
|
since: 0.50.0 |
|
description: | |
|
When true, this generated file is installed during |
|
the install step, and `install_dir` must be set and not empty. When false, this |
|
generated file is not installed regardless of the value of `install_dir`. |
|
When omitted it defaults to true when `install_dir` is set and not empty, |
|
false otherwise. |
|
|
|
install_dir: |
|
type: str |
|
description: | |
|
The subdirectory to install the generated file to |
|
(e.g. `share/myproject`), if omitted or given the value of empty |
|
string, the file is not installed. |
|
|
|
install_mode: |
|
type: list[str | int] |
|
since: 0.47.0 |
|
description: | |
|
Specify the file mode in symbolic format |
|
and optionally the owner/uid and group/gid for the installed files. |
|
|
|
See the `install_mode` kwarg of [[install_data]] for more information. |
|
|
|
install_tag: |
|
type: str |
|
since: 0.60.0 |
|
description: | |
|
A string used by the `meson install --tags` command |
|
to install only a subset of the files. By default the file has no install |
|
tag which means it is not being installed when `--tags` argument is specified. |
|
|
|
output: |
|
type: str |
|
description: | |
|
The output file name. *(since 0.41.0)* may contain |
|
`@PLAINNAME@` or `@BASENAME@` substitutions. In configuration mode, |
|
the permissions of the input file (if it is specified) are copied to |
|
the output file. |
|
|
|
output_format: |
|
type: str |
|
since: 0.47.0 |
|
description: | |
|
The format of the output to generate when no input |
|
was specified. It defaults to `c`, in which case preprocessor directives |
|
will be prefixed with `#`, you can also use `nasm`, in which case the |
|
prefix will be `%`. |
|
|
|
encoding: |
|
type: str |
|
default: "'utf-8'" |
|
since: 0.47.0 |
|
description: | |
