<excludefname_rule plat="mac" osVers="*"  ruleIsOptional="t" skipFirstCharThenStartsWith="users/" contains_1="/node_modules/" contains_2="*" doesNotContain="*" endsWith="*" hasFileExtension="*" />
<excludefname_rule plat="mac" osVers="*"  ruleIsOptional="t" skipFirstCharThenStartsWith="users/" contains_1="/.git/" contains_2="*" doesNotContain="*" endsWith="*" hasFileExtension="*" />

Need

Convert .mov/.MP4 to .gif

Reason

As a developer, I feel better to upload a short video when I create the pull request to show other viewers what I did in this PR. I tried .mov format directly got after finishing recording screen using Quicktime, however, gif offers preview in most web pages, and has smaller file size.

This is not limited to developer, anyone has this need can use this method to convert the files.

Installing SSHPASS

SSHPass is a tiny utility, which allows you to provide the ssh password without using the prompt. This will very helpful for scripting. SSHPass is not good to use in multi-user environment. If you use SSHPass on your development machine, it don't do anything evil.

Installing on Ubuntu

apt-get install sshpass

Installing on OS X

Problem

You wanna serve up static files, but are bored by the usual trick of:

python -m SimpleHTTPServer

This is pretty simple but why type this every time? Let's use Pow for some zero-effort web serving. If you have Pow already set up, then just drop the provided config.ru file into the root of your static files. Then link your directory into ~/.pow so Pow can see it and that's it!

Let's say you have a directory with mockups you wanna show people, they are in ~/Dropbox/Mockups/ then you might do this:

	" Generate compile_commands.json for clangd.
	" Prefer CMake export, else Ninja compdb, else Bear + Make with optional append:
	" First check is whether need for (re)generation be at all, then where relative
	" to the open file, then calling CMake, Ninja, or finally Bear if applicable (as
	" background jobs). To make those builders work more predictably, additional
	" flags are passed to ensure all files are indexed as, say, `bear -- make` falls
	" short in presence of build artifacts.

	if exists('b:did_c_compdb_ftplugin') \| finish \| endif
	let b:did_c_compdb_ftplugin = 1

	if app.apiVersion < 21 then
	return app.alert("This script requires Aseprite v1.3-rc1")
	end

	-- This script requires UI
	if not app.isUIAvailable then
	return
	end

	local sprite = app.cel.frame.sprite
