My first programming experience was a TRS-80 and BASIC. I am also self taught, no school. I went to college for land Surveying in the late 90's, used AutoCAD extensively, and now I program, go figure.
Why parsers? I think in 2008 or so I had a vision of just what a parser was and how primal the concept really is, it's what our brain does. Lexers and Parsers are a perfect mirror of how are brain receives, sorts and make meaning out of the randomness of life. So you could say it has been a mystical journey for me. :) haha Mike On Thu, Jul 9, 2015 at 1:53 PM, Frédéric THOMAS <webdoubl...@hotmail.com> wrote: > > Well not so much compilers, I am still a newbie when it comes to byte > code > > stuff and binary math/operations etc. > > > > But I know parsers/lexers/scanners/AST pretty freaking well. ;-) > > Hehe, except of the emitting part, that's all the compiler though, well > done !! ;-) > > I'm only an autodidact coder lover who started as kid with Basic, ASM, DOS > / Windows 3.0 programming, then, mainframe (Cobol / CICS), 12 years in > Microsoft dev, PHP / JS and full stack Java / Flex with all the common > testing / industrialisation tools around who is now interested in > compilers, better late than never but I have a lot to learn, it is so > different from all what I did before :-) > > Thanks again for your help. > Frédéric THOMAS > > > ---------------------------------------- > > Date: Thu, 9 Jul 2015 13:25:28 -0400 > > Subject: Re: [FalconJX] Collection Imports branch > > From: teotigraphix...@gmail.com > > To: dev@flex.apache.org > > > > On Thu, Jul 9, 2015 at 1:10 PM, Frédéric THOMAS <webdoubl...@hotmail.com > > > > wrote: > > > >>> It's antlr 3 grammar if I remember correctly, hah maybe even antlr 2.
