About

CLI and library implementation of [COCOMO] (Constructive Cost Model) estimates using [tokei] as a library to calculate total SLOC and [scc] as reference

See also [tokei#359].

Usage

```test $ cocomo -h COCOMO (Constructive Cost Model) CLI utility and library

Arguments: [PATH]... Files / Directories [default: .]

Options: --sloc Source lines of code [default: calculate from Files / Directories argument(s)] --average-wage Average Wage [default: 56286.0] --overhead Overhead [default: 2.4] --eaf Effort Adjustment Factor (EAF); typically 0.9 - 1.4 [default: 1.0] --project-type Project type [default: organic] [possible values: embedded, organic, semi-detached] --custom Custom parameters (a, b, c) --development-time Development time (d) [default: 2.5] --currency-symbol Currency symbol [default: $] -o, --output-format Output format [default: markdown-table] [possible values: markdown-table, sloccount] -h, --help Print help (see more with '--help') -V, --version Print version ```

Examples

Use [tokei] CLI to count lines of code in a given directory

Use [cocomo] to calculate COCOMO estimates

text $ cocomo ~/github.com/XAMPPRocky/tokei Description | Value ---------------------------|--------------------------------- Total Source Lines of Code | 5,567 Estimated Cost to Develop | $163,886.77 Estimated Schedule Effort | 6.92 months Estimated People Required | 2.10

Add -o sloccount to use the SLOCCount-style output format

text $ cocomo ~/github.com/XAMPPRocky/tokei -o sloccount Total Physical Source Lines of Code (SLOC) = 5,567 Development Effort Estimate, Person-Years (Person-Months) = 1.21 (14.56) (Basic COCOMO model, Person-Months = 2.40*(KSLOC**1.05)*1.00) Schedule Estimate, Years (Months) = 0.58 (6.92) (Basic COCOMO model, Months = 2.50*(person-months**0.38)) Estimated Average Number of Developers (Effort/Schedule) = 2.10 Total Estimated Cost to Develop = $163,887 (average salary = $56,286/year, overhead = 2.40)

Pass --sloc N to calculate COCOMO estimates for a given number of lines of code (without counting SLOC in any files or directories)

text $ cocomo --sloc 5567 Description | Value ---------------------------|--------------------------------- Total Source Lines of Code | 5,567 Estimated Cost to Develop | $163,886.77 Estimated Schedule Effort | 6.92 months Estimated People Required | 2.10
