To do so, a few dependencies have been imported: * external/bsd/lutok * external/mit/lua * external/public-domain/sqlite * external/public-domain/xz The Kyua framework is the new generation of ATF (Automated Test Framework), it is composed of: * external/bsd/atf * external/bsd/kyua-atf-compat * external/bsd/kyua-cli * external/bsd/kyua-tester * tests Kyua/ATF being written in C++, it depends on libstdc++ which is provided by GCC. As this is not part of the sources, Kyua is only compiled when the native GCC utils are installed. To install Kyua do the following: * In a cross-build enviromnent, add the following to the build.sh commandline: -V MKBINUTILS=yes -V MKGCCCMDS=yes WARNING: At this point the import is still experimental, and not supported on native builds (a.k.a make build).

/// Custom templating engine for text documents.

|
|
/// This module provides a simple mechanism to generate text documents based on
|
|
/// templates. The templates are just text files that contain template
|
|
/// statements that instruct this processor to perform transformations on the
|
|
/// input.
|
|
///
|
|
/// While this was originally written to handle HTML templates, it is actually
|
|
/// generic enough to handle any kind of text document, hence why it lives
|
|
/// within the utils::text library.
|
|
///
|
|
/// An example of how the templates look like:
|
|
///
|
|
/// %if names
|
|
/// List of names
|
|
/// -------------
|
|
/// Amount of names: %%length(names)%%
|
|
/// Most preferred name: %%preferred_name%%
|
|
/// Full list:
|
|
/// %loop names iter
|
|
/// * %%last_names(iter)%%, %%names(iter)%%
|
|
/// %endloop
