patign

patign

Align / format streams by pattern. "patign" is a portmanteau of "pattern" and "align".

install

go get github.com/nathanleclaire/patign

usage

Right now only piping from is supported, though that will change soon.

Imagine in file test.file you have something like :

"aws_resource" "droplet" {
    "ip" = "54.23.62.11"
    "foo" = "bar"
    "quuuuuuuuuuuuuux" = "spam"
    "amazon_secret_key" = "ASDFASDFASDFASDFASDFASDF"
    "amazon_id" = "asdffad,fdsa?"
}

(this example inspired by terraform configuration)

Wouldn't it be nice if all those = lined up?

Well, with patign, they can.

$ cat test.file | patign "=" 
"aws_resource" "droplet" {
    "foo"               = "bar"
    "quuuuuuuuuuuuuux"  = "spam"
    "amazon_secret_key" = "ASDFASDFASDFASDFASDFASDF"
    "amazon_id"         = "asdffad,fdsa?"
}

Another use case that I ran into the other day: let's say you have renamed a bunch of files in git.

$ git status
# On branch master
# Your branch is ahead of 'origin/master' by 1 commit.
#   (use "git push" to publish your local commits)
#
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   renamed:    test/a.txt -> test/b.txt
#   renamed:    test/barquux.java -> test/c.java
#   renamed:    test/foo.java -> test/d.java
#   renamed:    test/foobarwidgetfactory.java -> test/e.java
#   renamed:    test/randomlongname.java -> test/f.java
#   renamed:    test/somethingelesethatsstilldifferent.javca -> test/g.java

It's hard to parse the modified files. Can't they be more nicely formatted? With patign, they can.

$ git status | patign "-"
# On branch master
# Your branch is ahead of 'origin/master' by 1 commit.
#   (use "git push" to publish your local commits)
#
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   renamed:    test/barquux.java                            -> test/c.java
#   renamed:    test/foo.java                                -> test/d.java
#   renamed:    test/foobarwidgetfactory.java                -> test/e.java
#   renamed:    test/randomlongname.java                     -> test/f.java
#   renamed:    test/somethingelesethatsstilldifferent.javca -> test/g.java

disclaimer

Naturally it's still early days for patign and so there are rampant bugs, issues, etc. I'd love it if you'd contribute!
