ABAP minifier #76

Open larshp opened 8 years ago

larshp commented 8 years ago

As noted in https://github.com/larshp/abapGit/pull/467 the "compiled" version of abapGit is getting quite large.

As a joke I suggested writing a ABAP minifier, but perhaps it is not totally stupid?

Wonder how much the source code can be reduced if:

guess this would be a new project in some language that can run on travis(javascript?)

eduardocopat commented 8 years ago

Couldn't the abapMerge do this? Something like abapmerge --minify

larshp commented 8 years ago

yeah

Sirius-A commented 7 years ago

I wrote a minifier for abapmerge (See: https://github.com/Sirius-A/abapmerge)

Results

Normal ABAPGit:    1.31 MB (1375246 Bytes)
Minified AbapGit:   848 KB  (868582 Bytes)

-->minified version is around 60% of its normal size.

Note: I did not not test the minified code on a SAP system yet. I'll PR when I made sure it works.

did some testing, it seems like the editor and/or abap parser is not very happy with the very long 1 line of code.

perhaps try adding newline(at appropriate places) after each 1000 bytes

UPDATE: it looks like the editor automatically splits after 255 bytes image

One thing to consider might be that there are legacy function modules which read the uncompiled source code from the database and analyze it line by line with a line variable typed as CHAR80 which causes a dump if there is any line longer than 80 characters. I would not bother trying to support that, just so you know.
