fats is a cat-like dotnet tool to quickly dump multiple F# ranges from multiple files to stdout.
Please note: F# ranges use 1-based lines and 0-based columns.
Given a single path to a .sarif file, fats will dump the regions from the sarif results.

Installation

dotnet tool install --global fats

Usage

USAGE: fats.exe [--help] [--nomarkup] [<paths>...]

PATHS:

    <paths>...            the ranges to dump

OPTIONS:

    --nomarkup            don't use console markup like bold or underline
    --noprefix            don't dump line content before the range
    --nopostfix           don't dump line content after the range
    --help                display this list of options.

A single path argument consists of a file path followed by an optional colon and a range in parentheses.
Two types of ranges are currently supported:

(startLine-endLine) - a range of lines
(startLine,startColumn-endLine,endColumn) - a range of characters
(line,column) - a range of a single line

Between start and end line/column numbers there can be a single dash or multiple dashes.
The default output style is to print whole lines and to markup the exact range with an underline and a bold font. See the usage to control this.

Examples:

> fats "./src/Fats/Program.fs:(1,0-1,4)" "./src/Fats/Program.fs:(3,0--4,0)" "./src/Fats/Program.fs:(5,0--5,10)"

> fats --nomarkup "./src/Fats/Program.fs:(1,0-1,4)" "./src/Fats/Program.fs:(3,0--4,0)" "./src/Fats/Program.fs:(5,0--5,10)"

    type Line =

> fats  --nomarkup "./src/Fats/Program.fs(1-3)" # lines 1 to 3
namespace Fats

module Model =

> fats  --nomarkup "./src/Fats/Program.fs:(1,3)" # line containing the position
namespace Fats

> fats --nomarkup ./testbed.sarif
