+# Cli application based on ENM Topology Browser API
+
+[![NPM][npm-badge]][npm]
+[![LICENSE][license-badge]][license]
+[![dependencies][dependencies-badge]][dependencies-david]
+
+## Main goal
+
+Main features is type suggestions everywhere where it is possible and detailed attributes and values description available in config mode.
+
+## Installation
+
+First you need **node.js** which can be downloaded from official site nodejs.org and installed as described in the docs.
+
+Next clone or download this repository and run from the project root directory ...
+
+```
+npm i
+```
+
+... to install dependencies,
+
+```
+npm link
+```
+
+... to add application to your OS $PATH variable if you want to run it from anywhere.
+Now you can launch apllication
+
+```
+tplg-cli -l USERNAME -p PASSWORD -u https://enm.your.company.domian.com
+```
+
+## Usage
+
+Recommended environment is Windows Terminal (not _cmd.exe_) or any shell with rich formatting support. After application successfully launched you'll see root content and available commands.
+
+```
+PS C:\> tplg-cli -l USERNAME -p PASSWORD -u https://enm.your.company.domian.com
+✔ Login in...
+Authentication Successful
+✔ Starting Topology Browser...
+✔ Reading Topology...
+ SubNetwork=ONRM_ROOT_MO> (Use arrow keys or type to search)
+> SubNetwork=Core
+  SubNetwork=LTE
+  SubNetwork=RBS
+  SubNetwork=RNC
+  show
+  config
+  up
+  home
+  exit
+```
+
+### Commands
+
+> **Note:** _only `show` command can have parameter, all other commands haven't._
+
+- `show` - shows current object's attributes
+- `config` - enters _config_ mode
+- `up` - navigate up one level
+- `home` - navigate to root folder
+- `exit` - logout and exit application
+
+Start typing and you see only matches commands to your input.
+
+```
+SubNetwork=ONRM_ROOT_MO> subn
+> SubNetwork=Core
+  SubNetwork=LTE
+  SubNetwork=RBS
+  SubNetwork=RNC
+SubNetwork=ONRM_ROOT_MO> exi
+>exit
+```
+
+You can navigate to the next level selecting object ...
+
+```
+SubNetwork=ONRM_ROOT_MO> subn
+  SubNetwork=Core
+  SubNetwork=LTE
+  SubNetwork=RBS
+> SubNetwork=RNC
+SubNetwork=ONRM_ROOT_MO,SubNetwork=RNC>
+> MeContext=RNC01
+  MeContext=RNCTEST
+  MeContext=TEST
+```
+
+View objects attributes ...
+
+```

+  platformType: CPP
+```
+
+... show attributes with filter
+
+```

+> show type
+✔ Reading Topology...
+
+  FDN: SubNetwork=ONRM_ROOT_MO,SubNetwork=RNC,MeContext=RNC01
+
+  neType: RNC
+  platformType: CPP
+
+... Network=ONRM_ROOT_MO,SubNetwork=RNC,MeContext=RNC01>
+```
+
+Return one level up in FDN tree ...
+
+```
+... Network=ONRM_ROOT_MO,SubNetwork=RNC,MeContext=RNC01> up
+> up
+✔ Reading Topology...
+SubNetwork=ONRM_ROOT_MO,SubNetwork=RNC>
+```
+
+Return to the root from anywhere ...
+
+```
+... Network=ONRM_ROOT_MO,SubNetwork=RNC,MeContext=RNC01> home
+> home
+✔ Reading Topology...
+SubNetwork=ONRM_ROOT_MO>
+```
+
+And logout and exit ...
+
+```
+... Network=ONRM_ROOT_MO,SubNetwork=RNC,MeContext=RNC01> exit
+> exit
+✔ Logout...
+Logout OK
+PS C:\>
+```
+
+### Config Mode
+
+To modify attributes _config_ mode is used.
+
+Available commands are:
+
+- `commit` - commiting changes to the network
+- `check` - view configuration changes
+- `end` - end config mode without commiting
+- `exit` - logout and exit application
+
+```
+... ManagedElement=ERBS01,ENodeBFunction=1,EUtranCellFDD=test1> config
+> config
+✔ Reading Attributes...
+✔ Reading Attributes Data...
+
+    syncStatus: SYNCHRONIZED
+    ipAddress: 10.10.11.1

+    radioAccessTechnology: 4G, 3G
+
+... lement=ERBS01,ENodeBFunction=1,EUtranCellFDD=test1(config)# (Use arrow keys or type to search)
+> acBarringForCsfb
+  acBarringForEmergency
+  acBarringForMoData
+  acBarringForMoSignalling
+  ...
+  commit
+  check
+  end
+  exit
+(Move up and down to reveal more choices)
+```
+
+To modify attribute select it ...
+
+```
+... lement=ERBS01,ENodeBFunction=1,EUtranCellFDD=test1(config)# userLabel
+... ent=ERBS01,ENodeBFunction=1,EUtranCellFDD=test1(userLabel)#
+  commit
+  check
+  end
+  exit
+> get
+  set
+  description
+```
+
+Now you can get it ...
+
+```
+... ent=ERBS01,ENodeBFunction=1,EUtranCellFDD=test1(userLabel)# get
+> get
+
+  FDN: SubNetwork=ONRM_ROOT_MO,SubNetwork=RBS,MeContext=ERBS01,ManagedElement=1,ENodeBFunction=1,EUtranCellFDD=test1(userLabel)
+
+  userLabel: test1
+
+  Type: STRING
+
+```
+
+And set it's value ...
+
+```
+... ent=ERBS01,ENodeBFunction=1,EUtranCellFDD=test1(userLabel)# set
+? userLabel (STRING): ? test_label
+```
+
+Check configuration before applying
+
+```
+... ent=ERBS01,ENodeBFunction=1,EUtranCellFDD=test1(userLabel)# check
+
+  FDN: SubNetwork=ONRM_ROOT_MO,SubNetwork=RBS,MeContext=ERBS01,ManagedElement=ERBS01,ENodeBFunction=1,EUtranCellFDD=test1
+
+  userLabel: test_label

+## Contribution
+
+1. [Fork it]
+2. Create your feature branch (`git checkout -b my-new-feature`)
+3. Commit your changes (`git commit -am 'Add some feature'`)
+4. Push to the branch (`git push origin my-new-feature`)
+5. Create new Pull Request
+
+## Known Issues
+
+### flickering issue
+
+In some windows terminal spinner may look flickery. To fix this you need to modify file ./node_modules/ora/index.js
+
+Add 1 to _clearLine()_ on this line
+
+```javascript
+this.stream.clearLine(1);
+```
+
+### Issue with type SHORT
+
+EMN returns error if commited configuration includes attributes with type SHORT. It is not an application issue and should be fixed in API by Ericsson.
