@joyeecheung do you mind if I take over this PR and rebase it? I have some ideas I would like to build on top of this :) |
This makes it easier to use third-party dependencies in this tool (e.g. adding compression using algorithms not available in Python). It is also much faster - locally js2c.py takes ~1.5s to generate the output whereas this version takes ~0.1s - and consumes less memory (~110MB v.s. 66MB). This also modifies the js2c.py a bit to simplify the output, making it easier to compare with one generated by the C++ version. Locally the output from the two are identical. We'll remove js2c.py in a subsequent commit when the C++ version is used by default.

I actually had the rebase locally, and was just waiting for the two other js2c changes to land before I could push it (and also, waiting for reviews, which this still doesn't have...so ping @nodejs/build @nodejs/build-files again..) |

tools: port js2c.py to C++
This makes it easier to use third-party dependencies in this tool
(e.g. adding compression using algorithms not available in Python).
It is also much faster - locally js2c.py takes ~1.5s to generate the
output whereas this version takes ~0.1s - and consumes less memory
(~110MB v.s. 66MB).
This also modifies the js2c.py a bit to simplify the output, making
it easier to compare with one generated by the C++ version. Locally
the output from the two are identical. We'll remove js2c.py in a
subsequent commit when the C++ version is used by default.
build: replace js2c.py with js2c.cc
Locally, running the two version for the first time (when the output does not yet exist so no reading is done):
And running for the second time (reading the existing output and not overwriting since the content isn't going to change):
