Description:
shcmdmgr 0.1.1
DISCLAIMER (WORK IN PROGRESS):
As of May 2020 this project is work in progress.
The alpha release is planned for June.
It IS designed to
make a clear overview of custom-made commands
provide a common user interface for the commands
provide a clear way to setup commands which work well with this tool
It IS NOT designed to
provide standard functions or libraries to be used in the custom-made commands
check correctness or analyse the commands
TODOs
refine the structure of modules
fix over-escaping, e.g. in 'proot' test command
improve search (not only one whole regex)
help for arguments
completion for arguments
think of possible project configuration variables
fix optional parameter load order
release to pypi and get it tested by somebody else
(seems hard) copy the command into command line instead of executing it
Installation
For stable release, run
pip3 install shcmdmgr
Basic usage
Use cmd -s (or cmd --save) to catalogue a command. For example lsb_release -a.
$ lsb_release -a
Distributor ID: Ubuntu
Description: Ubuntu 20.04 LTS
Release: 20.04
Codename: focal
$ cmd --save
The command to be saved: lsb_release -a % note that this was pre-filled from history
Alias: sysversion
Short description: Shows the system version
Run the command either by invoking the alias
$ cmd sysversion
Distributor ID: Ubuntu
Description: Ubuntu 20.04 LTS
Release: 20.04
Codename: focal
or use search cmd -f (or cmd --find) to find and run the command.
$ cmd --find
========================================
query $ system % items matching the regex are displayed
--- 1 ------------------------------
cmd: do-release-upgrade
des: Upgrades the system to the newest released version
--- 2 ------------------------------
cmd: lsb_release -a
des: Shows the system version
========================================
query $ 2 % choose the command by entering its number
run command: lsb_release -a
Distributor ID: Ubuntu
Description: Ubuntu 20.04 LTS
Release: 20.04
Codename: focal
To edit the command catalogue run cmd --edit (or cmd -e) which runs $EDITOR ./<script_location>/commands.json command or open and edit the catalogue file manually.
$ cmd --edit
% The "$EDITOR" opens the content similar to the following
[
{
"command": "lsb_release -a",
"description": "Show the version number of the system",
"alias": "sysversion",
"creation_time": "2020-04-11 00:24:27"
},
{
"command": "do-release-upgrade",
"description": "Upgrades the system to the newest released version",
"alias": "sysupgrade",
"creation_time": "2020-04-11 00:25:08"
}
]
Completion
Completion is supported in bash and zsh shells, and must be enabled explicitly.
Installing the completion is the matter of adding file-source to the RC file.
The correct command can be emited by invoking --completion <shell> command.
So you can use the following for bash or zsh respectively.
cmd --completion bash >> ~/.bashrc
cmd --completion zsh >> ~/.zshrc
Advanced (work in progress)
Installation
To get the latest (non-stable) development version run the following.
pip3 install git+https://github.com/vaclavblazej/shell-command-manager.git
For development setup you may fork the repository, clone it, and create a symlink.
git clone git@github.com:vaclavblazej/shell-command-manager.git
ln -s "$PWD/shell-command-manager/bin/cmd.sh" ~/bin/cmd
Parts
We manage custom scripts, their help, and completion.
execution
help
completion
One function for all three because they have too much in common.
Flags used to determine what we want to return.
All three variants are delegated lower (into arguments) and in the lowest level, we return (or do) the wanted result.
In execution, we perform the task.
In help and completion, we set the result into the relevant location.
Execution
The custom script should be an executable file.
Help
Help is invoked by calling script --help <arguments> where arguments are in the precise form as they would have been without the --help argument.
It prints a string to standard output which describes what our current command does, and if there are any expected arguments.
Completion
Completion is invoked by calling script --complete <arguments> and prints out the list of words which are sensible arguments in the next places.
The last argument is considered as argument prefix and is used to filter out possible words.
If no filtering is wanted, the last argument should be empty-string.
