Crate rusty_dumb_tools 

A collection of simple tools in Rust as Rust modules:

• crate::arg::DumbArgParser: A simple argument parser.
• crate::progress::DumbProgressIndicator: A simple Iterator wrapper that helps to show progress of iteration.
• crate::json::DumbJsonProcessor: A simple JSON processor / stream parser. It can be useful for handling command line argument parsing.
• crate::calc::DumbCalcProcessor: A simple infix calculation processor.
• crate::calculator::DumbCalculator: A simple calculator that accepts input keys acting like a real calculator. It can be used to implement a simple calculator UI.
• crate::ltemp::DumbLineTemplate: A simple line template for formatting a line, which can be use to print values as a line with some template.
• crate::lblscreen::DumbLineByLineScreen: A terminal / text-based “screen” update helper, which is extended from crate::ltemp::DumbLineTemplate, and should be helpful in managing the updates of the formatted lines that acts as a “screen”.

For a demo program of using the tools, you may want to run the included demo function demo::run_demo like

use rusty_dumb_tools::demo;
// demo::run_demo(None);  // get arguments from command-line         
demo::run_demo(Some(vec!["calc", "-h"]));  // pass in explicit arguments        

Assuming new Rust project with main.rs like

use rusty_dumb_tools::demo;
fn main() {
   demo::run_demo(None);
}

the demo can be cargo run like

• cargo run -- -h
• cargo run -- calc -h
• cargo run -- calc 1.1 + 2.2 * (4.3 - 2.4) + 5
• cargo run -- calc-repl
• cargo run -- ltemp Trevor
• cargo run -- lblscreen
• cargo run -- arg -f 0.2 5 --string2 VAL1 false 1 2 3

Enjoy!

Peace be with you! May God bless you! Jesus loves you! Amazing Grace!

Modules

arg

A simple argument parser – crate::arg::DumbArgParser

calc

A simple infix calculation processor – crate::calc::DumbCalcProcessor

calculator

A simple calculator that accepts input keys acting like a real calculator. It is base on crate::calc::DumbCalcProcessor for it’s calculation processing.

demo

Home for rusty_dumb_tools demo, and sub-demos for the various tools included in this crate. Please refer to crate::demo::run_demo.

json

A simple JSON processor / stream parser – crate::json::DumbJsonProcessor

lblscreen

A simple terminal / text-based “screen” update helper – crate::lblscreen::DumbLineByLineScreen

ltemp

A simple line template for formatting a line, which can be use for printing values as a line with some template – crate::ltemp::DumbLineTemplate

prelude

All the common ‘uses’ of this crate – use rusty_dumb_tools::prelude::*;

progress

A simple Iterator wrapper that helps to show progress of iteration – crate::progress::DumbProgressIndicator

shared

Things shared by the different tools of this crate.

Macros

dap_arg

use this macro to create a DumbArgBuilder instance to build argument object (argument specification) to be added to DumbArgParser with DumbArgBuilder::add_to the macro accepts one for more strings (positional argument name or flags) like

dlt_comps

use this macro to compose DumbLineTemplate components

dltc

use this macro to construct a value-mapped DumbLineTemplate component (a MappedLineTempCompBuilder to be precise), and it is expected to be use together with dlt_comps!

dpi_into_iter

use this macro to wrap a Vec into_iter() with DumbProgressIndicator to show progress of iteration

dpi_iter

use this macro to wrap a Vec iter() with DumbProgressIndicator to show progress of iteration

dpir

use this macro to wrap a Range with DumbProgressIndicator to show progress of iteration

dpiw

use this macro to wrap an Iterator with DumbProgressIndicator to show progress of iteration

sap_arg

please consider using the macro crate::dap_arg! instead, since this macro will be deprecated
