* Fix binary-sizes.py scriptdevelDaniel Mueller2020-07-26
| | | | | | | A while back we removed the nitrocli/ directory in the repository root. Unfortunately, we missed that the binary-sizes.py script relied on the previous directory structure. This change adjusts the script to work with the new structure.
* Correctly use doc comments in macrosDaniel Mueller2020-07-03
| | | | | | | | | | | | | | | | Our custom macros for conveniently creating types with additional meta information for working with structopt do not actually use the doc comments we have in place -- these comments are solely for in-source documentation. We are an application and as such crates.io will not automatically generate documentation. All of that does not deter rustc from complaining that doc comments are unused. In the past we tried to fudge that by adding a special allowance, #[allow(unused_doc_comments)], but that seems to have seized to work. With this change we finally give in and move the doc comment into the macro itself, where it will be used to annotate the generated type. This step should hopefully silence rustc once and for all -- at the expense of a slight decrease in readability.
* Rename arg_defs.rs to args.rsDaniel Mueller2020-04-11
| | | | | | We have never been fully satisfied with the name arg_defs. Now that we have gotten rid of the formerly used args module, this change renames arg_defs to args.
* Add test for bash completion functionalityDaniel Mueller2020-04-05
| | | | | | | | | This change adds a test for the previously introduced bash completion functionality. To test the generated completion script, we spin up a bash instance, source the script, and then perform a completion as the shell would do it. It seems impossible to convince compgen to do the heavy lifting for us and so we invoke the completion function with the expected environment variables present.
* Add support for generating a bash completion scriptDaniel Mueller2020-04-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | This change adds support for generating a bash completion script. If sourced, the shell will provide tab completions for the program's arguments. There are two possible approaches provided by clap for going about generating shell completion functionality: either at build time, by separately generating the clap parsers out-of-band, or at run time, as an option to the main program itself. We are generally not too much in favor of a run time approach, as it means less inspectability at installation time and more overhead in the form of code crammed into the main binary. Hence, with this change we take the "build time" approach. Clap recommends hooking the generation up in build.rs, but this seems like an inflexible choice. For one, that is because it would mean unconditionally generating this file or using some user-unfriendly environment variable based approach for making the process conditional. But there is also the fact that specifying the command for which to generate the script should likely be configurable. That is a limitation of the completion script that clap generates (see https://github.com/clap-rs/clap/issues/1764). In our version we provide a utility program that emits the completion script to standard output, accepting regular command line options itself. In doing so we allow for installation time generation of the completion script or installation of the utility itself, the output of which could be sourced on demand -- depending on the user's preference.
* Move nitrocli source code into repository rootDaniel Mueller2020-04-04
Now that all vendored dependencies have been removed, this change moves the program's source code from the nitrocli/ directory into the root of the repository.
