Optimizing app size (for aplite): script to show code space size for every function. I noticed that you can read size of every function from build/pebble-app.map. So, here's a script to do it :)).

_pebble_function_size.sh

#!/usr/bin/env bash

cat ./build/pebble-app.map |

 # pick important part of file
 sed -n -e "/^ \*(\.text\.\*)/,/^ \*(\.rodata)/p" |
 # remove first and last line
 sed -e "1d" -e "\$d" |

 # ensure every function is on single line:
 # remove all newlines
 sed -e :a -e '$!N; s/\n/ /; ta' |
 # replace .text. with \n.text. (add newlines)
 sed -e $'s/\.text\./\\\n.text./g' |

 # cut into columns:
 # replace whitespaces with ;
 sed -e 's/  */;/g' |
 # extract columns 1-3
 cut -d ';' -f1 -f2 -f3 |

 # remove .text. from function name
 sed -e 's/^\.text\.//g' |

 # columns: 1 = function name, 2 = fn start offset, 3 = fn code length
 # print <length> <function>
 awk -F ';' '{printf "%d %s\n", $3+0, $1 }' |
  # general numeric (-g) sort by 1st column
 sort -r -t ' ' -k 1,1 -g |

 cat

Hi, awesome work. It's really helped me take a look at functions that seem to be occupying the most space and easily reading that extensive .map file.

Oddly enough, I got an error from line 20, saying that only one type of list may be specified. Commenting out the line though worked. The cut command claims that it can only do one cut operation at some point, so maybe that's related? I don't have any experience in bash scripting, so I found it out already odd that it didn't work for me when trying to just "plug and play".

Anyway, thank you for sharing this!
