gantt

An OmniPlan competitor written in Bourne shell.

Overview

Usage: gantt [OPTION]... [FILE]... Prints a gantt chart from a specially formatted 'agenda' input.

File should be in the form... TASK: SUBTASK: (status|<INT>[-<INT>])

With no FILE, standard input is read.

-h, --hours-per-day=NUM Hours of work per day. -t, --tasks=LIST Comma-separated list of tasks to include. Tasks are referenced by index in the order they appear. --help Print this help. --help-example Print an input example. --version Print version information.

Display can be customized with the following environment variables: GANTT_CHART_CHARACTER_MAX (Default: ▒) - Character to use for 'maximum estimate' portion of bars. GANTT_CHART_CHARACTER_MIN (Default: █) - Character to use for 'minumum estimate' portion of bars. GANTT_CHART_CHARACTER_TIMELINE (Default: •) - Character to use for the timeline decoration.

Piping to a pager is recommended if output exceeds your terminal width.

.Example input:

This is an example of the input gantt expects.

Lines starting with a '#' are ignored.

Whitespace padding is also ignored.

Hint: try piping this output back into gantt to see the visual output.
