Multitool

small tools each less than 1000 lines of code

Installation From Source

1. make sure you have Go installed and put $GOPATH/bin in your $PATH
2. clone this repository while navigated to $GOPATH/src/github.com/rigelrozanski/ with git clone https://github.com/rigelrozanski/multitool.git
3. go to the repo directory with cd $GOPATH/src/github.com/rigelrozanski/multitool
4. run make install

Slack

Often when attempting to copy and paste text from a slack conversation there is excess whitespace and timestamps riddled throughout. This tool will remove the whitespace and pesky timestamps automatically within the clipboard. Usage

<copy text to the clipboard from slack>
mt slck [names]
<paste text into desired output>

Note that the [names] arguments are optional but add extra whitespace between the conversation paragraphs from different participants. The name is the slack handle of the participant.

Got

Adapted from https://github.com/ebuchman/got

Got is a tool for doing things with go and git that the go tool doesn't do for you by default. It's particularly useful for working with forks of open source projects, where import paths become an issue.

Usage

Replace strings in an entire directory tree

got replace [-d <depth> -p <dirpath>] <oldString> <newString>

Switch import paths to upstream repo, pull, switch back

got pull <remote> <branch>

This does the same thing as running replace, followed by a commit, followed by a git pull, followed by a replace which undoes the first replace.

Check out the same branch across many repositories

got checkout develop

This will cd into every directory in the current one and run git checkout develop. If you want to specify exceptions, add arguments of the form <repo>:<branch>, ie

got checkout develop myrepo:newfeature repo2:master

will cd into every repo and run git checkout develop except in myrepo it will do git checkout newfeature and in repo2 will do git checkout master. To only cd into some directories, just list them, ie.

got checkout develop myrepo anotherepo repo2:master

will checkout myrepo and anotherepo onto develop and repo2 onto master while leaving all others alone.

See which branch every repo in a directory is on

got branch

Toggle the import path in a go directory between the Godep/ vendored packages and the $GOPATH based location

got dep --local github.com/myorg/myrepo

and

got dep --vendor github.com/myorg/myrepo

Book Binding Commands

The first step once you have your pdf is to separate out the pdf into a folder of all the images (one image for each page in the pdf book). To accomplish this I use a command line program named "magick" which can be downloaded here: (https://imagemagick.org/script/download.php) 

magick convert -density 300 input.pdf -quality 100 -depth 8 -sharpen 0x1.0
~/Desktop/temp/output-%04d.png

For instance if you were navigated to your Desktop within terminal (cd ~/Desktop) The above command would convert a file on your desktop that was named "input.pdf" into a folder of images within a new folder "temp" on your desktop. NOTE this step can take a LONG time to run, like 45min+ depending on the size of your book, I think that if you replace "input.pdf" with "input.pdf[1-3]" in the above command it will do this task for only 3 pages (taking much less time) which will give you a sense if the command is working or not.

The next step is to reorder all those images for proper printing and further add them all to a single pdf. This is accomplished with my little be piece of software. The software will need to get compile from source, here is the link to the code and the installation instructions

https://github.com/rigelrozanski/multitool#installation-from-source

Once installed the command you could use from your Desktop within terminal is: 

mt pdf alt-book "temp/"

(optional step) if you want to get fancy and change the margins around a bit to maximize the text size on the page you can play with the margins with the following flags (change those 0.3 numbers around, they're the margin in inches)

mt pdf alt-book "temp/" --xmar 0.3 --ymar 0.3 

This would compile all the images into your desired file... once you have that file, it'll be dead easy to print/cut/bind.
