From a68c9238111c6caee78bb28f8054b8f0cfa0e374 Mon Sep 17 00:00:00 2001 From: Christian Poessinger Date: Thu, 24 Feb 2022 22:47:12 +0100 Subject: scripts: T4269: node.def generator should automatically add default values Since introducing the XML node it was common, but redundant, practice to also add a help string indicating which value would be used as default if the node is unset. This makes no sense b/c it's duplicated code/value/characters and prone to error. The node.def scripts should be extended to automatically render the appropriate default value into the CLI help string. For e.g. SSH the current PoC renders: $ cat templates-cfg/service/ssh/port/node.def multi: type: txt help: Port for SSH service (default: 22) val_help: u32:1-65535; Numeric IP port ... Not all subsystems are already migrated to get_config_dict() and make use of the defaults() call - those subsystems need to be migrated, first before the new default is added to the CLI help. --- scripts/build-command-templates | 17 +++++++++++++---- 1 file changed, 13 insertions(+), 4 deletions(-) (limited to 'scripts/build-command-templates') diff --git a/scripts/build-command-templates b/scripts/build-command-templates index d8abb0a13..876f5877c 100755 --- a/scripts/build-command-templates +++ b/scripts/build-command-templates @@ -117,7 +117,7 @@ def collect_validators(ve): return regex_args + " " + validator_args -def get_properties(p): +def get_properties(p, default=None): props = {} if p is None: @@ -125,7 +125,12 @@ def get_properties(p): # Get the help string try: - props["help"] = p.find("help").text + help = p.find("help").text + if default != None: + # DNS forwarding for instance has multiple defaults - specified as whitespace separated list + tmp = ', '.join(default.text.split()) + help += f' (default: {tmp})' + props["help"] = help except: pass @@ -134,7 +139,11 @@ def get_properties(p): vhe = p.findall("valueHelp") vh = [] for v in vhe: - vh.append( (v.find("format").text, v.find("description").text) ) + format = v.find("format").text + description = v.find("description").text + if default != None and default.text == format: + description += f' (default)' + vh.append( (format, description) ) props["val_help"] = vh except: props["val_help"] = [] @@ -271,7 +280,7 @@ def process_node(n, tmpl_dir): print("Name of the node: {0}.
