Participants' native languages: Chinese (2), Dutch, English, Finnish, French (2), Greek, Hebrew, Italian (3), Korean, Persian (2), Polish, Portuguese, Romanian (3), Russian, Spanish, Swedish (2), Swiss German, West-Assyrian - 24 students, 17 languages + 2 teachers, 1 more language

Formal grammar is no more expected to match natural language exactly

analysis: should be wider than the language (we will use UD)
generation: should be contained in the language (we will use GF)
in both formats, we aim to use universal concepts for many languages

Phrase structure grammars, context-free = BNF, grammar rules, trees

example: english.cf
testing grammars in GF: import, generate_random, parse, linearize, visualize_parse, help

GF grammars: dividing .cf into abstract and concrete .gf

example: Intro*.gf
forms of rules: cat, fun, lincat, lin
word order switch English-Italian

Agreement, parameter definitions, variable and inherent features, linearization types

IntroEng.gf

For you to do:

write a concrete syntax for some other language, carefully thinking about

GF for ARM Mac (M1, M2, M3): https://www.grammaticalframework.org/~aarne/gf-mac.gz

After download, open a terminal and do:

 mkdir tmp  # in your home directory
 cd tmp
 mv ~/Downloads/gf-mac.gz .
 gunzip gf-mac.gz
 mv gf-mac gf
 chmod a+x gf
 ./gf

You should now see the GF promt. Type 'help' to see if it works!

The next thing is to move it to a place where you can find it from anywhere in your system. One standard place is

  mv gf /usr/local/bin

If you get "permission denied", you will have to write

  sudo mv gf /usr/local/bin

and type your computer's password.

Then you can try

  cd
  gf

to verify that GF works in your home directory.

After that, you can test it in the course GitHub directory

  cd comp-syntax-gu-mlt/lectures/lecture-02
  gf
  > import IntroEng.gf   # in GF

You can work here for a while. The next step will be to install the RGL, but this can wait a bit. The instructions in https://www.grammaticalframework.org/download/index-3.11.html should work even for the ARM Mac.
