"""Module implementing the command line entry point for post-processing outputs.
This module can be executed from the command line using the following
approaches::
python -m robot.rebot
python path/to/robot/rebot.py
Instead of ``python`` it is possible to use also other Python interpreters.
This module is also used by the installed ``rebot`` start-up script.
This module also provides :func:`rebot` and :func:`rebot_cli` functions
that can be used programmatically. Other code is for internal usage.

USAGE = """Rebot -- Robot Framework report and log generator
Version: <VERSION>
Usage: rebot [options] robot_outputs
or: python -m robot.rebot [options] robot_outputs
or: python path/to/robot/rebot.py [options] robot_outputs
Rebot can be used to generate logs and reports in HTML format. It can also
produce new XML output files which can be further processed with Rebot or
other tools.
The easiest way to execute Rebot is using the `rebot` command created as part
of the normal installation. Alternatively it is possible to execute the
`robot.rebot` module directly using `python -m robot.rebot`, where `python`
can be replaced with any supported Python interpreter. Yet another alternative
is running the `robot/rebot.py` script like `python path/to/robot/rebot.py`.
Inputs to Rebot are XML output files generated by Robot Framework or by earlier
Rebot executions. When more than one input file is given, a new top level test
suite containing suites in the given files is created by default. This allows
combining multiple outputs together to create higher level reports. An
exception is that if --merge is used, results are combined by adding suites
and tests in subsequent outputs into the first suite structure. If same test
is found from multiple outputs, the last one replaces the earlier ones.
For more information about Rebot and other built-in tools, see
http://robotframework.org/robotframework/#built-in-tools. For more details
about Robot Framework in general, go to http://robotframework.org.
Options
=======
--rpa Turn on the generic automation mode. Mainly affects
terminology so that "test" is replaced with "task"
in logs and reports. By default the mode is got
from the processed output files.
-R --merge When combining results, merge outputs together
instead of putting them under a new top level suite.
Example: rebot --merge orig.xml rerun.xml
-N --name name Set the name of the top level suite.
-D --doc documentation Set the documentation of the top level suite.
Simple formatting is supported (e.g. *bold*). If
the documentation contains spaces, it must be quoted.
If the value is path to an existing file, actual
documentation is read from that file.
Examples: --doc "Very *good* example"
--doc doc_from_file.txt
-M --metadata name:value * Set metadata of the top level suite. Value can
contain formatting and be read from a file similarly
as --doc. Example: --metadata Version:1.2
-G --settag tag * Sets given tag(s) to all tests.
-t --test name * Select tests by name or by long name containing also
parent suite name like `Parent.Test`. Name is case
and space insensitive and it can also be a simple
pattern where `*` matches anything, `?` matches any
single character, and `[chars]` matches one character
in brackets.
--task name * Alias to --test. Especially applicable with --rpa.
-s --suite name * Select suites by name. When this option is used with
--test, --include or --exclude, only tests in
matching suites and also matching other filtering
criteria are selected. Name can be a simple pattern
similarly as with --test and it can contain parent
name separated with a dot. For example, `-s X.Y`
selects suite `Y` only if its parent is `X`.
-i --include tag * Select tests by tag. Similarly as name with --test,
tag is case and space insensitive and it is possible
to use patterns with `*`, `?` and `[]` as wildcards.
Tags and patterns can also be combined together with
`AND`, `OR`, and `NOT` operators.
Examples: --include foo --include bar*
--include fooANDbar*
-e --exclude tag * Specify tests not to be included by tag. They are not
selected even if included with --include. Tags are
matched using same rules as with --include.
--processemptysuite Processes output also if the top level suite is
empty. Useful e.g. with --include/--exclude when it
is not an error that there are no matches.
Use --skiponfailure when starting execution instead.
-d --outputdir dir Where to create output files. The default is the
directory where Rebot is run from and the given path
is considered relative to that unless it is absolute.
-o --output file XML output file. Not created unless this option is
specified. Given path, similarly as paths given to
--log, --report and --xunit, is relative to
--outputdir unless given as an absolute path.
-l --log file HTML log file. Can be disabled by giving a special
name `NONE`. Default: log.html
Examples: `--log mylog.html`, `-l none`
-r --report file HTML report file. Can be disabled with `NONE`
similarly as --log. Default: report.html
-x --xunit file xUnit compatible result file. Not created unless this
option is specified.
-T --timestampoutputs When this option is used, timestamp in a format
`YYYYMMDD-hhmmss` is added to all generated output
files between their basename and extension. For
example `-T -o output.xml -r report.html -l none`
creates files like `output-20070503-154410.xml` and
`report-20070503-154410.html`.
--splitlog Split the log file into smaller pieces that open in
browsers transparently.
--logtitle title Title for the generated log file. The default title
is `<SuiteName> Log`.
--reporttitle title Title for the generated report file. The default
title is `<SuiteName> Report`.
--reportbackground colors Background colors to use in the report file.
Given in format `passed:failed:skipped` where the
`:skipped` part can be omitted. Both color names and
codes work.
Examples: --reportbackground green:red:yellow
--reportbackground #00E:#E00
-L --loglevel level Threshold for selecting messages. Available levels:
TRACE (default), DEBUG, INFO, WARN, NONE (no msgs).
Use syntax `LOGLEVEL:DEFAULT` to define the default
visible log level in log files.
Examples: --loglevel DEBUG
--loglevel DEBUG:INFO
--suitestatlevel level How many levels to show in `Statistics by Suite`
in log and report. By default all suite levels are
shown. Example: --suitestatlevel 3
--tagstatinclude tag * Include only matching tags in `Statistics by Tag`
in log and report. By default all tags are shown.
Given tag can be a pattern like with --include.
--tagstatexclude tag * Exclude matching tags from `Statistics by Tag`.
This option can be used with --tagstatinclude
similarly as --exclude is used with --include.
--tagstatcombine tags:name * Create combined statistics based on tags.
These statistics are added into `Statistics by Tag`.
If the optional `name` is not given, name of the
combined tag is got from the specified tags. Tags are
matched using the same rules as with --include.
Examples: --tagstatcombine requirement-*
--tagstatcombine tag1ANDtag2:My_name
--tagdoc pattern:doc * Add documentation to tags matching the given
pattern. Documentation is shown in `Test Details` and
also as a tooltip in `Statistics by Tag`. Pattern can
use `*`, `?` and `[]` as wildcards like --test.
Documentation can contain formatting like --doc.
Examples: --tagdoc mytag:Example
--tagdoc "owner-*:Original author"
--tagstatlink pattern:link:title * Add external links into `Statistics by
Tag`. Pattern can use `*`, `?` and `[]` as wildcards
like --test. Characters matching to `*` and `?`
wildcards can be used in link and title with syntax
%N, where N is index of the match (starting from 1).
Examples: --tagstatlink mytag:http://my.domain:Title
--tagstatlink "bug-*:http://url/id=%1:Issue Tracker"
--expandkeywords name:<pattern>|tag:<pattern> *
Matching keywords will be automatically expanded in
the log file. Matching against keyword name or tags
work using same rules as with --removekeywords.
Examples: --expandkeywords name:BuiltIn.Log
--expandkeywords tag:expand
--removekeywords all|passed|for|wuks|name:<pattern>|tag:<pattern> *
Remove keyword data from all generated outputs.
Keywords containing warnings are not removed except
in the `all` mode.
all: remove data from all keywords
passed: remove data only from keywords in passed
test cases and suites
for: remove passed iterations from for loops
while: remove passed iterations from while loops
wuks: remove all but the last failing keyword
inside `BuiltIn.Wait Until Keyword Succeeds`
name:<pattern>: remove data from keywords that match
the given pattern. The pattern is matched
against the full name of the keyword (e.g.
'MyLib.Keyword', 'resource.Second Keyword'),
is case, space, and underscore insensitive,
and may contain `*`, `?` and `[]` wildcards.
Examples: --removekeywords name:Lib.HugeKw
--removekeywords name:myresource.*
tag:<pattern>: remove data from keywords that match
the given pattern. Tags are case and space
insensitive and patterns can contain `*`,
`?` and `[]` wildcards. Tags and patterns
can also be combined together with `AND`,
`OR`, and `NOT` operators.
Examples: --removekeywords foo
--removekeywords fooANDbar*
--flattenkeywords for|while|iteration|name:<pattern>|tag:<pattern> *
Flattens matching keywords in all generated outputs.
Matching keywords get all log messages from their
child keywords and children are discarded otherwise.
for: flatten FOR loops fully
while: flatten WHILE loops fully
iteration: flatten FOR/WHILE loop iterations
foritem: deprecated alias for `iteration`
name:<pattern>: flatten matched keywords using same
matching rules as with
`--removekeywords name:<pattern>`
tag:<pattern>: flatten matched keywords using same
matching rules as with
`--removekeywords tag:<pattern>`
--starttime timestamp Set execution start time. Timestamp must be given in
format `2007-10-01 15:12:42.268` where all separators
are optional (e.g. `20071001151242268` is ok too) and
parts from milliseconds to hours can be omitted if
they are zero (e.g. `2007-10-01`). This can be used
to override start time of a single suite or to set
start time for a combined suite, which would
otherwise be `N/A`.
--endtime timestamp Same as --starttime but for end time. If both options
are used, elapsed time of the suite is calculated
based on them. For combined suites, it is otherwise
calculated by adding elapsed times of the combined
suites together.
--nostatusrc Sets the return code to zero regardless are there
failures. Error codes are returned normally.
--prerebotmodifier class * Class to programmatically modify the result
model before creating outputs.
-C --consolecolors auto|on|ansi|off Use colors on console output or not.
auto: use colors when output not redirected (default)
on: always use colors
ansi: like `on` but use ANSI colors also on Windows
off: disable colors altogether
-P --pythonpath path * Additional locations to add to the module search path
that is used when importing Python based extensions.
-A --argumentfile path * Text file to read more arguments from. File can have
both options and output files, one per line. Contents
do not need to be escaped but spaces in the beginning
and end of lines are removed. Empty lines and lines
starting with a hash character (#) are ignored.
Example file:
| --include regression
| --name Regression Tests
| # This is a comment line
| output.xml
-h -? --help Print usage instructions.
--version Print version information.
Options that are marked with an asterisk (*) can be specified multiple times.
For example, `--test first --test third` selects test cases with name `first`
and `third`. If an option accepts a value but is not marked with an asterisk,
the last given value has precedence. For example, `--log A.html --log B.html`
creates log file `B.html`. Options accepting no values can be disabled by
using the same option again with `no` prefix added or dropped. The last option
has precedence regardless of how many times options are used. For example,
`--merge --merge --nomerge --nostatusrc --statusrc` would not activate the
merge mode and would return a normal return code.
Long option names are case and hyphen insensitive. For example, --TagStatLink
and --tag-stat-link are equivalent to, but easier to read than, --tagstatlink.
Long options can also be shortened as long as they are unique.
Environment Variables
=====================
REBOT_OPTIONS Space separated list of default options to be placed
in front of any explicit options on the command line.
ROBOT_SYSLOG_FILE Path to a file where Robot Framework writes internal
information about processed files. Can be useful when
debugging problems. If not set, or set to special
value `NONE`, writing to the syslog file is disabled.
ROBOT_SYSLOG_LEVEL Log level to use when writing to the syslog file.
Available levels are the same as for --loglevel
command line option and the default is INFO.
