chfritz / meteor_deps.sh
Created August 4, 2015 03:54
A script for checking the two-step package dependencies of a meteor project, i.e., the package dependencies of direct dependencies (as seen in `meteor list`).
meteor list | grep ^[a-z] | tr -s ' ' | cut -d ' ' -f1,2 | tr -d '\*\+' | tr ':' '_' \
| while read X Y; do \
cat ~/.meteor/packages/$X/$Y/web.browser.json \
| xargs -0 node -e "X = JSON.parse(process.argv[1]); \
X.uses.forEach(function(d) { \
console.log(\"$X\", \"$Y\", d.package, d.constraint); \
})"; \
done | sort

A tiny bash script that loads a given JSON file into an interactive node.js shell. Once the shell is loaded, look at the variable `json`.
#!/bin/bash
# explore a JSON file in node.js
# run: seejson.sh file.json
# then look at "json" in the opening node shell
node -e "json = require(\"./$1\"); repl = require(\"repl\").start(\"> \"); console.log(\"loaded... see json\");"

chfritz / squeezing.tex
Created December 5, 2013 23:15
A tex file full of tricks for squeezing a latex document. Clearly you should avoid using these tricks. But when the deadline is near and you see no other way, you can use it to quickly change the formatting slightly to get more space. Just comment in some of the length changes or add other for the described sizes.
