module documentation

Library for supporting message and service generation for all ROS client libraries. This is mainly responsible for calculating the md5sums and message definitions of classes.

Function	`compute_full_text`	Compute full text of message/service, including text of embedded types. The text of the main msg/srv is listed first. Embedded msg/srv files are denoted first by an 80-character '=' separator, followed by a type declaration line,'MSG: pkg/type', followed by the text of the embedded type.
Function	`compute_full_type_name`	Compute the full type name of message/service 'pkg/type'.
Function	`compute_md5`	Compute md5 hash for message/service
Function	`compute_md5_text`	Compute the text used for md5 calculation. MD5 spec states that we removes comments and non-meaningful whitespace. We also strip packages names from type names. For convenience sake, constants are reordered ahead of other declarations, in the order that they were originally defined.
Function	`_compute_hash`	subroutine of compute_md5()
Function	`_unique_deps`	Undocumented

def compute_full_text(msg_context, spec): ¶

Compute full text of message/service, including text of embedded types. The text of the main msg/srv is listed first. Embedded msg/srv files are denoted first by an 80-character '=' separator, followed by a type declaration line,'MSG: pkg/type', followed by the text of the embedded type.

Parameters
msg_context	`MsgContext` instance to load dependencies into/from.
spec	`MsgSpec` to compute full text for.
Returns
concatenated text for msg/srv file and embedded msg/srv types, `str`

def compute_full_type_name(package_name, file_name): ¶

Compute the full type name of message/service 'pkg/type'.

Parameters
package_name	name of package file is in, `str`
file_name	Undocumented
Returns
typename in format 'pkg/type'
Raises
`Unknown exception`	`MsgGenerationException` if file_name ends with an unknown file extension
Unknown Field: file_name
name of the msg or srv file, `str`

def compute_md5(msg_context, spec): ¶

Compute md5 hash for message/service

Parameters
msg_context	`MsgContext` instance to load dependencies into/from.
spec	`MsgSpec` to compute md5 for.
Returns
md5 hash, `str`

def compute_md5_text(msg_context, spec): ¶

Compute the text used for md5 calculation. MD5 spec states that we removes comments and non-meaningful whitespace. We also strip packages names from type names. For convenience sake, constants are reordered ahead of other declarations, in the order that they were originally defined.

Returns
text for ROS MD5-processing, `str`

def _compute_hash(msg_context, spec, hash): ¶

subroutine of compute_md5()

Parameters
msg_context	`MsgContext` instance to load dependencies into/from.
spec	`MsgSpec` to compute hash for.
hash	hash instance

def _unique_deps(dep_list): ¶

Undocumented
