reuse.header module#

Functions for manipulating the comment headers of files.

exception reuse.header.MissingReuseInfo[source]#

Bases: Exception

Some REUSE information is missing from the result.

reuse.header.add_new_header(text: str, reuse_info: ReuseInfo, template: Template | None = None, template_is_commented: bool = False, style: Type[CommentStyle] | None = None, force_multi: bool = False, merge_copyrights: bool = False) → str[source]#

Add a new header at the very top of text, similar to find_and_replace_header. But in this function, do not replace any headers or search for any existing REUSE information.

Raises:

CommentCreateError – if a comment could not be created.

reuse.header.create_header(reuse_info: ReuseInfo, header: str | None = None, template: Template | None = None, template_is_commented: bool = False, style: Type[CommentStyle] | None = None, force_multi: bool = False, merge_copyrights: bool = False) → str[source]#

Create a header containing reuse_info. header is an optional argument containing a header which should be modified to include reuse_info. If header is not given, a brand new header is created.

template, template_is_commented, and style determine what the header will look like, and whether it will be commented or not.

Raises:
reuse.header.find_and_replace_header(text: str, reuse_info: ReuseInfo, template: Template | None = None, template_is_commented: bool = False, style: Type[CommentStyle] | None = None, force_multi: bool = False, merge_copyrights: bool = False) → str[source]#

Find the first SPDX comment block in text. That comment block is replaced by a new comment block containing reuse_info. It is formatted as according to template. The template is normally uncommented, but if it is already commented, template_is_commented should be True.

If both style and template_is_commented are provided, style is only used to find the header comment.

If the comment block already contained some REUSE information, that information is merged into reuse_info.

If no header exists, one is simply created.

text is returned with a new header.

Raises:
