From 24d63cd8a9ace35d0b3d29d6a2369bb62712c2d6 Mon Sep 17 00:00:00 2001 From: Alex Palaistras Date: Sun, 25 Aug 2019 16:30:34 +0100 Subject: [PATCH] Implement initial version of Grawkit Web Playground Running `grawkit` locally can be a hassle for one-off tasks, and can be hard to iterate against when plotting graphs based on complex command-line descriptions. Given recent fixes for POSIX compatibility, this commit implements a basic web-based "playground"-style application that allows for entering command-line descriptions in an HTML textarea, and seeing the results (or errors) instantly. The playground application itself is built in Go (Awk itself would be insufficient for the throughput required, but may be investigated in the future), with the excellent GoAwk library providing parsing and execution duties, therefore making for a pure-Go implementation (other than Grawkit itself). Additional support for setting custom styling and an online deployment with Docker are forthcoming. --- LICENSE | 4 +- play/README.md | 21 + play/go.mod | 5 + play/go.sum | 2 + play/play.go | 187 ++++++++ play/static/apple-touch-icon.png | Bin 0 -> 8059 bytes play/static/css/main.css | 122 +++++ play/static/css/normalize.css | 427 ++++++++++++++++++ play/static/css/skeleton.css | 418 +++++++++++++++++ play/static/favicon.ico | Bin 0 -> 4286 bytes play/static/img/logo.png | Bin 0 -> 7055 bytes play/static/js/main.js | 42 ++ play/static/template/default-content.template | 11 + play/static/template/default-preview.template | 26 ++ play/static/template/index.template | 49 ++ 15 files changed, 1312 insertions(+), 2 deletions(-) create mode 100644 play/README.md create mode 100644 play/go.mod create mode 100644 play/go.sum create mode 100644 play/play.go create mode 100644 play/static/apple-touch-icon.png create mode 100644 play/static/css/main.css create mode 100644 play/static/css/normalize.css create mode 100644 play/static/css/skeleton.css create mode 100644 play/static/favicon.ico create mode 100644 play/static/img/logo.png create mode 100644 play/static/js/main.js create mode 100644 play/static/template/default-content.template create mode 100644 play/static/template/default-preview.template create mode 100644 play/static/template/index.template diff --git a/LICENSE b/LICENSE index 1777578..24e4d44 100644 --- a/LICENSE +++ b/LICENSE @@ -1,4 +1,4 @@ -Copyright (c) 2016 Alex Palaistras +Copyright (c) 2019 Alex Palaistras Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal @@ -16,4 +16,4 @@ FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

About the Grawkit Playground

+

+ This is an online version of the Grawkit tool for + building SVG graphs based on command-line descriptions of git commands. +

+

+ Simply fill in the textarea with git commands, as you would enter these in the + command-line, and press 'Generate' to return an SVG graph representation. +

+

Features

+

+ This can currently parse the following (to varying degrees): +

+
    +
  • git branch for creating named branches
    • +
  • git commit for adding commit markers on branches
    • +
  • git checkout for changing branch contexts
    • +
  • git merge for generating merges between branches
    • +
  • git tag for adding labels to specific commits
    • +
+
