The Lounge What is on Your Mind? PHP Man Pages Now Available (Over 10,000) Post 302886454 by Neo on Friday 31st of January 2014 03:47:01 PM

OK. I found out why apropos does not work for the PHP manpages.

apropos is dependent on parsing the formatted manpages to create the whatis database for each manpage set, as discussed in mandb

Where we see:

Quote:
DIAGNOSTICS
The following warning messages can be emitted during database building.

<filename>: whatis parse for page(sec) failed
An attempt to extract whatis line(s) from the given <filename>
failed. This is usually due to a poorly written manual page,
but if many such messages are emitted it is likely that the sys-
tem contains non-standard manual pages which are incompatible
with the man-db whatis parser. See the WHATIS PARSING section
in lexgrog(1) for more information.
So, I used lexgrog on the PHP manpages and got the parse error; and when I examined the PHP manpages files, it's easy to see the pages are very poorly formatted (compared to "standard" manpages for linux and osx) and would require a lot of reformatting to get the parser to work so whatis would work, etc.

Hahaha... if anyone cares to reformat over 10,000 PHP pages so the lexgrog parser works on the PHP manpages, please raise your hand... otherwise, well will accept the fact that the PHP manpages will not be including in our recursive apropos (whatis) search.

apropos(1)						      General Commands Manual							apropos(1)

NAME
apropos - Locates reference pages by keyword SYNOPSIS
apropos keyword... The apropos command shows which reference pages contain instances of any of the given keywords in their purpose lines. OPTIONS
Specifies the word(s) for which apropos should search. DESCRIPTION
In looking for keywords, apropos considers each word separately and ignores the case of letters. Words that are part of other words are also considered; thus, when looking for the word compile, apropos will also find all instances of compiler. If the output of the apropos command begins with a name and reference section number, you can enter man section name. For example, if the output of the apropos command is make(1u), you can enter man 1u make to obtain the reference page on System V version of the make command. The apropos command works just like the man command with the -k option. EXAMPLES
To find reference pages with the keyword password in the purpose line, enter: apropos password FILES
Keyword database. SEE ALSO
Commands: man(1), whatis(1), catman(8) apropos(1)
