- test rendered recipe lines
- test evaluated recipe lines
- properly handle state stack at EOF
- implement string parsing
. use the same rules as rust: https://doc.rust-lang.org/reference.html#string-literals
. \xHH, \u{HHHHHH}, \n, \r, \t, \0, \\, \{ no other escapes
. '' strings with no escapes
- assignment
. make quine use assignment and interpolation
- do proper handling of the state stack at EOF
- disallow unused arguments and variables
- allow exporting environment variables
- write some tests to test the binary itself and all command line flags
- test that run runs first recipe by default
- parse arguments on command line:
. ugly but conservative: j build --set a=hello
. by export: A=HELLO j build
. by export 2: BUILD.A=HELLO j build
. by name: j build a=hello
. by position: j build hello
. with marker: j build hello : clean hello :
. after -- : j build -- foo baz
- integration testing
. run app with command line options and test output
. exercise all features and all command line options
. test that first recipe runs by default
- underline problem token in error messages
- add context to unexpected_token error
"while parsing a recipe"
"while parsing an expression"
- figure out argument passing:
. flag: j build --set a=hello
. by export: A=HELLO j build
. by export 2: BUILD.A=HELLO j build
. by name: j build a=hello
. by position: j build hello
. with marker: j build hello : clean hello :
. after -- : j build -- foo baz
. fast errors when arguments are missing
. could also allow this to override variables
although maybe only after a '--': j build -- a=hello
. sub arguments into recipes
- change error messages to underline problem token
- allow calling recipes in a justfile in a different directory:
- just ../foo # ../justfile:foo
- just xyz/foo # xyz/justfile:foo
- just xyz/ # xyz/justfile:DEFAULT
- this is going to be hard. should a single recipe with a slash
require that all recipes have slashes?
or should non-slash recipes still run in this directory?
will need to change things a great deal
- indentation is line continuation
- should i disallow a shebang recipe where the shebang isn't on the first line?
- add insane borrow checker issue to issue tracker
- add context to unexpected_token error
"while parsing a recipe"
"while parsing an expression"
- add post requirements:
# do c then a then b
a: c b~
- before release:
- rewrite grammar.txt
- change name back to 'just'
. suggest j as alias
- create some kind of group feedback forum:
. email list, reddit
- change name back to 'just', suggest j as alias
- change description to "a polyglot command runner"?
- update readme
- document all code, including private stuff

. lay out the structure of the code, mention tests, give tips
for contributing
- vim and emacs syntax hilighting (use makefile syntax hilighting for now)
- split up code into modules for easier reading
. parsing
. tokenizing
. executing
- make sure there isn't any unused code
- ask users to contribute their justfiles
- try to get some users

enhancements:
- add post requirements:
# do c then a then b
a: c b~
- allow calling recipes in a justfile in a different directory:
. just ../foo # ../justfile:foo
. just xyz/foo # xyz/justfile:foo
. just xyz/ # xyz/justfile:DEFAULT
. get all directories, if more than one, fork just for each
- allow setting and exporting environment variables
- indentation or slash for line continuation
