Since we + # install the headers to `/usr/include/QuotientE2EE` to prevent conflicts + # with software that use the official non-encryption package, we need to + # adjust the include statements in the headers to make sure that the right + # ones are used. We can't do this in the `prepare()` step because the build + # system stores the headers alongside the source code in a directory called + # `Quotient` and we therefore cannot change the include statements without + # also moving the entire source tree.

The `\1` in the replacement means to include the text + # which matched the first sub-expression verbatim. + # - `[[:blank:]]*` matches an arbitrary amount of white-space (space or + # horizontal tab characters) + # - Places where a forward slash needs to be part of the expression or + # replacement text are escaped with a backslash, i.e. `\/` + # - So the expression reads: match all instances of text which are of the + # form `# include <Quotient/`, with everything but the final forward + # slash contained in a sub-expression, and with an arbitrary amount of + # white-space allowed + # - And the replacement text will be whatever text matched the first + # sub-expression (i.e. `# include <Quotient` but with the right amount + # of white-space) followed by `E2EE/`. + find "${pkgdir}/usr/include/QuotientE2EE" -name '*.h' -exec sed -i \ + 's/\(#[[:blank:]]*include[[:blank:]]*<Quotient\)\//\1E2EE\//g' '{}' \; } |
