## Customized platform.local.txt to compile for mbed targets under Windows
## This recipe works around the Windows limit of 32k characters in a cmd line by calling .o files from a text file during linking
## Install: put file under your mbed sub-directory - ie: C:\Users\MYUSER\AppData\Local\Arduino15\packages\arduino\hardware\mbed\1.1.4
## You can also find the local arduino folder in the IDE under File -> Preferences -> see preferences.txt location in the bottom part of the window

## hooks

# create a txt file with all object file paths from libraries and sketch folders (core\variant.cpp.o needed too for linking)
recipe.hooks.linking.prelink.1.pattern=cmd /c dir /b /s {build.path}\sketch\*.o > {build.path}\obj_files_tmp.txt
recipe.hooks.linking.prelink.2.pattern=cmd /c "dir /b /s {build.path}\libraries\*.o >> {build.path}\obj_files_tmp.txt 2>nul & exit 0"
recipe.hooks.linking.prelink.3.pattern=cmd /c echo "{build.path}\core\variant.cpp.o" >> {build.path}\obj_files_tmp.txt

# replace \ by \\ in file paths (otherwise escaped by linker) and save in new txt file
recipe.hooks.linking.prelink.4.pattern=cmd /v /c "@echo off && for /f %a in ({build.path}\obj_files_tmp.txt) do (set line=%a && set line=!line:\=\\! && echo !line! >> {build.path}\obj_files.txt)"

# delete txt file after linking
recipe.hooks.linking.postlink.1.pattern=cmd /c del {build.path}\obj_files.txt
