Any program (person), that produces man pages, should check the output for defects by using (both groff and nroff) [gn]roff -mandoc -t -ww -b -z -K utf8 The same goes for man pages that are used as an input. For a style guide use mandoc -T lint -.- So any 'generator' should check its products with the above mentioned 'groff', 'mandoc', and additionally with 'nroff ...'. This is just a simple quality control measure. The 'generator' may have to be corrected to get a better man page, the source file may, and any additional file may. Common defects: Input text line longer than 80 bytes. Not removing trailing spaces (in in- and output). The reason for these trailing spaces should be found and eliminated. Not beginning each input sentence on a new line. Lines should thus be shorter. See man-pages(7), item 'semantic newline'. -.- The difference between the formatted output of the original and patched file can be seen with: nroff -mandoc > nroff -mandoc > diff -u and for groff, using "printf '%s\n%s\n' '.kern 0' '.ss 12 0' | groff -mandoc -Z - " instead of 'nroff -mandoc' Add the option '-t', if the file contains a table. Read the output of 'diff -u' with 'less -R' or similar. -.-. If 'man' (man-db) is used to check the manual for warnings, the following must be set: The option "-warnings=w" The environmental variable: export MAN_KEEP_STDERR=yes (or any non-empty value) or (produce only warnings): export MANROFFOPT="-ww -b -z" export MAN_KEEP_STDERR=yes (or any non-empty value) -.-. Output from "mandoc -T lint dcb-buffer.8": (possibly shortened list) mandoc: dcb-buffer.8:6:2: WARNING: skipping paragraph macro: sp after SH -.-. Change (or include a "FIXME" paragraph about) misused SI (metric) numeric prefixes (or names) to the binary ones, like Ki (kibi), Mi (mebi), Gi (gibi), or Ti (tebi), if indicated. If the metric prefixes are correct, add the definitions or an explanation to avoid misunderstanding. 96:Set sizes of all buffers to 10KB, except for buffer 6, which will have the size 100:# dcb buffer set dev eth0 buffer-size all:10K 6:1M 109:buffer-size 0:10Kb 1:10Kb 2:10Kb 3:10Kb 4:10Kb 5:10Kb 6:1Mb 7:10Kb 111:total-size 1222Kb -.-. Use the correct macro for the font change of a single argument or split the argument into two. 19:.RI DEV 26:.RI DEV -.-. Add a comma (or \&) after "e.g." and "i.e.", or use English words (man-pages(7)). Abbreviation points should be protected against being interpreted as an end of sentence, if they are not, and that independent of the current place on the line. 61:i.e. as used with the \fBset\fR command. For the \fBshow\fR command, the -.-. Wrong distance between sentences in the input file. Separate the sentences and subordinate clauses; each begins on a new line. See man-pages(7) ("Conventions for source file layout") and "info groff" ("Input Conventions"). The best procedure is to always start a new sentence on a new line, at least, if you are typing on a computer. Remember coding: Only one command ("sentence") on each (logical) line. E-mail: Easier to quote exactly the relevant lines. Generally: Easier to edit the sentence. Patches: Less unaffected text. Search for two adjacent words is easier, when they belong to the same line, and the same phrase. The amount of space between sentences in the output can then be controlled with the ".ss" request. 55:priority, and sizes of those buffers. It can be also used to inspect the current 61:i.e. as used with the \fBset\fR command. For the \fBshow\fR command, the 62:parameter name is to be used as a simple keyword without further arguments. This 63:instructs the tool to show the value of a given parameter. When no parameters 69:buffers. This might be more than a simple sum of individual buffer sizes if 76:for details. Keys are priorities, values are buffer indices. For each priority 83:for details. Keys are buffer indices, values are sizes of that buffer in bytes. -.-. Split lines longer than 80 characters into two or more lines. Appropriate break points are the end of a sentence and a subordinate clause; after punctuation marks. Line 49, length 82 .IR SIZE " := { " INTEGER " | " INTEGER\fBK\fR " | " INTEGER\fBM\fR " | " ... " }" -.-. Use the name of units in text; use symbols in tables and calculations. The rule is to have a (no-break, \~) space between a number and its units (see "www.bipm.org/en/publications/si-brochure") 100:# dcb buffer set dev eth0 buffer-size all:10K 6:1M 109:buffer-size 0:10Kb 1:10Kb 2:10Kb 3:10Kb 4:10Kb 5:10Kb 6:1Mb 7:10Kb 111:total-size 1222Kb -.-.
