-Command Line Usage
+Command-Line Usage
------------------
The :mod:`trace` module can be invoked from the command line. It can be as
simple as ::
- python -m trace --count somefile.py ...
+ python -m trace --count -C . somefile.py ...
-The above will generate annotated listings of all Python modules imported during
-the execution of :file:`somefile.py`.
+The above will execute :file:`somefile.py` and generate annotated listings of
+all Python modules imported during the execution into the current directory.
-The following command-line arguments are supported:
+.. program:: trace
+
+.. cmdoption:: --help
+
+ Display usage and exit.
+
+.. cmdoption:: --version
+
+ Display the version of the module and exit.
+
+Main options
+^^^^^^^^^^^^
+
+At least one of the following options must be specified when invoking
+:mod:`trace`. The :option:`--listfuncs <-l>` option is mutually exclusive with
+the :option:`--trace <-t>` and :option:`--counts <-c>` options . When
+:option:`--listfuncs <-l>` is provided, neither :option:`--counts <-c>` nor
+:option:`--trace <-t>` are accepted, and vice versa.
+
+.. program:: trace
+
+.. cmdoption:: -c, --count
+
+ Produce a set of annotated listing files upon program completion that shows
+ how many times each statement was executed. See also
+ :option:`--coverdir <-C>`, :option:`--file <-f>` and
+ :option:`--no-report <-R>` below.
+
+.. cmdoption:: -t, --trace
-:option:`--trace`, :option:`-t`
Display lines as they are executed.
-:option:`--count`, :option:`-c`
- Produce a set of annotated listing files upon program completion that shows how
- many times each statement was executed.
+.. cmdoption:: -l, --listfuncs
+
+ Display the functions executed by running the program.
+
+.. cmdoption:: -r, --report
-:option:`--report`, :option:`-r`
Produce an annotated list from an earlier program run that used the
- :option:`--count` and :option:`--file` arguments.
+ :option:`--count <-c>` and :option:`--file <-f>` option. This does not
+ execute any code.
-:option:`--no-report`, :option:`-R`
- Do not generate annotated listings. This is useful if you intend to make
- several runs with :option:`--count` then produce a single set of annotated
- listings at the end.
+.. cmdoption:: -T, --trackcalls
+
+ Display the calling relationships exposed by running the program.
+
+Modifiers
+^^^^^^^^^
+
+.. program:: trace
+
+.. cmdoption:: -f, --file=<file>
-:option:`--listfuncs`, :option:`-l`
- List the functions executed by running the program.
+ Name of a file to accumulate counts over several tracing runs. Should be
+ used with the :option:`--count <-c>` option.
-:option:`--trackcalls`, :option:`-T`
- Generate calling relationships exposed by running the program.
+.. cmdoption:: -C, --coverdir=<dir>
-:option:`--file`, :option:`-f`
- Name a file containing (or to contain) counts.
+ Directory where the report files go. The coverage report for
+ ``package.module`` is written to file :file:`{dir}/{package}/{module}.cover`.
-:option:`--coverdir`, :option:`-C`
- Name a directory in which to save annotated listing files.
+.. cmdoption:: -m, --missing
-:option:`--missing`, :option:`-m`
When generating annotated listings, mark lines which were not executed with
- '``>>>>>>``'.
+ ``>>>>>>``.
-:option:`--summary`, :option:`-s`
- When using :option:`--count` or :option:`--report`, write a brief summary to
- stdout for each file processed.
+.. cmdoption:: -s, --summary
-:option:`--ignore-module`
- Accepts comma separated list of module names. Ignore each of the named
- module and its submodules (if it is a package). May be given
- multiple times.
+ When using :option:`--count <-c>` or :option:`--report <-r>`, write a brief
+ summary to stdout for each file processed.
-:option:`--ignore-dir`
- Ignore all modules and packages in the named directory and subdirectories
- (multiple directories can be joined by os.pathsep). May be given multiple
- times.
+.. cmdoption:: -R, --no-report
+ Do not generate annotated listings. This is useful if you intend to make
+ several runs with :option:`--count <-c>`, and then produce a single set of
+ annotated listings at the end.
-.. _trace-api:
+.. cmdoption:: -g, --timing
+
+ Prefix each line with the time since the program started. Only used while
+ tracing.
+
+Filters
+^^^^^^^
+
+These options may be repeated multiple times.
+
+.. program:: trace
+
+.. cmdoption:: --ignore-module=<mod>
+
+ Ignore each of the given module names and its submodules (if it is a
+ package). The argument can be a list of names separated by a comma.
-Programming Interface
----------------------
+.. cmdoption:: --ignore-dir=<dir>
+ Ignore all modules and packages in the named directory and subdirectories.
+ The argument can be a list of directories separated by :data:`os.pathsep`.

.. class:: Trace([count=1[, trace=1[, countfuncs=0[, countcallers=0[, ignoremods=()[, ignoredirs=()[, infile=None[, outfile=None[, timing=False]]]]]]]]])
- Create an object to trace execution of a single statement or expression. All
- parameters are optional. *count* enables counting of line numbers. *trace*
- enables line execution tracing. *countfuncs* enables listing of the functions
- called during the run. *countcallers* enables call relationship tracking.
- *ignoremods* is a list of modules or packages to ignore. *ignoredirs* is a list
- of directories whose modules or packages should be ignored. *infile* is the
- file from which to read stored count information. *outfile* is a file in which
- to write updated count information. *timing* enables a timestamp relative
- to when tracing was started to be displayed.

+
+ .. method:: run(cmd)
+
+ Execute the command and gather statistics from the execution with
+ the current tracing parameters. *cmd* must be a string or code object,
+ suitable for passing into :func:`exec`.
+
+ .. method:: runctx(cmd[, globals=None[, locals=None]])
+
+ Execute the command and gather statistics from the execution with the
+ current tracing parameters, in the defined global and local
+ environments. If not defined, *globals* and *locals* default to empty
+ dictionaries.
+
+ .. method:: runfunc(func, *args, **kwds)
+ Call *func* with the given arguments under control of the :class:`Trace`
+ object with the current tracing parameters.
-.. method:: Trace.run(cmd)
+ .. method:: results()
- Run *cmd* under control of the Trace object with the current tracing parameters.
+ Return a :class:`CoverageResults` object that contains the cumulative
+ results of all previous calls to ``run``, ``runctx`` and ``runfunc``
+ for the given :class:`Trace` instance. Does not reset the accumulated
+ trace results.
+.. class:: CoverageResults
-.. method:: Trace.runctx(cmd[, globals=None[, locals=None]])
+ A container for coverage results, created by :meth:`Trace.results`. Should
+ not be created directly by the user.
- Run *cmd* under control of the Trace object with the current tracing parameters
- in the defined global and local environments. If not defined, *globals* and
- *locals* default to empty dictionaries.
+ .. method:: update(other)
+ Merge in data from another :class:`CoverageResults` object.
-.. method:: Trace.runfunc(func, *args, **kwds)
+ .. method:: write_results([show_missing=True[, summary=False[, coverdir=None]]])
- Call *func* with the given arguments under control of the :class:`Trace` object
- with the current tracing parameters.
+ Write coverage results. Set *show_missing* to show lines that had no
+ hits. Set *summary* to include in the output the coverage summary per
+ module. *coverdir* specifies the directory into which the coverage
+ result files will be output. If ``None``, the results for each source
+ file are placed in its directory.
