indentation in source rST for documentation The rST manual pages for bpftool would use a mix of tabs and spaces for indentation. While this is the norm in C code, this is rather unusual for rST documents, and over time we've seen many contributors use a wrong level of indentation for documentation update. Let's fix bpftool's indentation in docs once and for all: - Let's use spaces, that are more common in rST files. - Remove one level of indentation for the synopsis, the command description, and the "see also" section. As a result, all sections start with the same indentation level in the generated man page. - Rewrap the paragraphs after the changes. There is no content change in this patch, only indentation and rewrapping changes. The wrapping in the generated source files for the manual pages is changed, but the pages displayed with "man" remain the same, apart from the adjusted indentation level on relevant sections. [ Quentin: rebased on bpf-next, removed indent level for command description and options, updated synopsis, command summary, and "see also" sections. ] Signed-off-by: Rameez Rehman Signed-off-by: Quentin Monnet Signed-off-by: Daniel Borkmann Link: https://lore.kernel.org/bpf/20240331200346.29118-2-qmo@kernel.org tools/bpf/bpftool/Documentation/Makefile | 6 +- tools/bpf/bpftool/Documentation/bpftool-btf.rst | 104 +++-- tools/bpf/bpftool/Documentation/bpftool-cgroup.rst | 224 ++++++----- .../bpf/bpftool/Documentation/bpftool-feature.rst | 115 +++--- tools/bpf/bpftool/Documentation/bpftool-gen.rst | 338 ++++++++-------- tools/bpf/bpftool/Documentation/bpftool-iter.rst | 58 ++- tools/bpf/bpftool/Documentation/bpftool-link.rst | 73 ++-- tools/bpf/bpftool/Documentation/bpftool-map.rst | 232 ++++++----- tools/bpf/bpftool/Documentation/bpftool-net.rst | 112 +++--- tools/bpf/bpftool/Documentation/bpftool-perf.rst | 34 +- tools/bpf/bpftool/Documentation/bpftool-prog.rst | 436 ++++++++++----------- .../bpftool/Documentation/bpftool-struct_ops.rst | 81 ++-- tools/bpf/bpftool/Documentation/bpftool.rst | 60 +-- tools/bpf/bpftool/Documentation/common_options.rst | 26 +- 14 files changed, 908 insertions(+), 991 deletions(-) accumulated error probability: 0.00 culprit signature: 75344a95765cf7c603aa64ef59309baef29ad8dfd8bbccea1634424300cfd4a9 parent signature: 66edc404d35b94c99995a2bd02bf5d150573302a6d61f6babdb27e686dc584f9 reproducer is flaky (0.55 repro chance estimate) revisions tested: 26, total time: 4h58m38.027988925s (build: 1h54m18.001064835s, test: 2h33m16.06633665s) first good commit: f7b68543642136164ce7348945d3ada707c4e635 bpftool: Use simpler indentation in source rST for documentation recipients (to): ["daniel@iogearbox.net" "qmo@kernel.org" "rameezrehman408@hotmail.com"] recipients (cc): []
