makepplog option ...

mppl option ...

Makepp by default writes a detailed log of its decision finding and actions. So as to not waste its time with pretty printing, this data is dumped in a compact, cryptic format. This tool does the pretty printing and filtering in various formats. For a less detailed but prettier graphical view see makeppgraph.

This is solely based on the contents of the log file (.makepp/log), so it can be performed at any time as long as you preserve the file, and even on a different machine. Every time makepp stops when running with option "--loop", you get a page break. Valid options are:

-A filename

--args-file=filename

--arguments-file=filename

Read the file and parse it as possibly quoted whitespace- and/or newline-separated options.

-c

--current-working-directory

-C number

--current-working-directory-and-up=number

The first two options strip the current directory from the front of all filenames it outputs. The second two additionally replace number directories up from here, with the necessary number of ../ entries.

These options only work meaningfully when you call makepplog in the same directory makepp ran, or one near there.

-d

--set-directory

Virtually switch to the directory where the log file was originally produced. If you copied or moved it from there, this is necessary for "-c" (which is implied by this option) to shorten the original path.

-f

--follow

As in "tail" command, process more lines of logfile as it grows.

-?

-h

--help

Print out a brief summary of the options.

-i

--install-dirs

--installation-directories

These options replace the invocation of makepp and the pathes to the built in makefiles with .../ so as to keep odd pathes out of your sight.

-k list

--keys=list

--keylist=list

The list specifies one or more space separated Shell style patterns (with [xyz], ?, *, {a,bc,def}). Remember to protect these from your Shell by quoting. These are matched against the message keys (as shown by "--showkey"). Each pattern may be preceded with an exclamation mark ("!") or a caret ("^") to exclude the matched keys from those selected before instead of adding them to the selection. If the first pattern starts with an exclamation mark, it operates on all keys. There are a few key prefixes with fixed meanings so you can select categories of keys:

BC*

All build cache related messages.

BUILD*

All build reason related messages.

LOAD*

All makefile loading related messages.

REP*

All repository related messages.

RULE*

All rule related messages.

SCAN*

All scanning related messages.

    --keys='LOAD* RULE*'        # Only makefile loading and rule messages.
    --keys='!BUILD* *CMD'       # No build messages, except BUILD_CMD.

-K

--showkey

This prefixes each output line with the internal name of the message key, for later use with "--keys".

-l filename

--log=filename

--log-file=filename

The filename is to where makepp wrote its log. It may also be a directory, in which a file called .makepp/log or log will be searched. To read from stdin, you must give - as a filename. When this option is not given, it defaults to the current directory.

This option can be given multiple times, e.g. for merging all the logs from "--traditional-recursive-make". But it will get the message version information, which keeps track of message formats, only from the first file. So if you feed it log files from different version of makepp in the same invocation, output can get a bit messed up.

-n

--no-indent

Makepp puts indentation information into the log file to show you what happened because of what else. This option turns indentation off.

-o filename

--output=filename

Write the output to this file, rather than stdout.

-p

--prefix

Prefix every structured message with the string ``makepplog: ''. IDEs like Emacs can then parse the lines and hyperlink to the mentioned files.

-t

--tabulate

Put each list item on a new line, rather than outputting a line that can easily become longer than a screenful.

-u

--uniq

--unique

Report each found include statement and each scan output only once.

-V

--version

Print out the version number.

EXAMPLES

If you want to know which file includes which other file, and nothing else:

    makeppclean -r
    makepp                      # Full build to scan all source files.
    makepplog -p '/^INCL$/'

If you want to format lines with a prefix so Emacs' compilation-mode can parse the lines and exclude all scanning related messages:

    makepplog -mp '!/^SCAN/'

If you want to explore which keys you can exclude or include in the above manners:

    makepplog -kn
