Created March 26, 2018 22:17
capture search to a variable for later re-use in Vim

The expression below captures the first group match and adds its to a list for later use.

let t =[] | '<,'>s/\v\\code\{([^}]+)}\zs/\=add(t, submatch(1))[1:0]/g

We can then place the list into another section of the file with.

put = t

Last active January 30, 2018 22:22
Installing python with pyenv

pyenv was failing to install python due the inexistence of the pyexpat library.

In order to solve this problem, I upgraded brew, installed and uninstalled openssl with brew and installed the HEAD version of pyenv.

Before installing the required python versions I exported the following flags:

CFLAGS="-I$(brew --prefix openssl)/include"
LDFLAGS="-L$(brew --prefix openssl)/lib"
