Takes a process and a signal to send. Class: class:word | Namespace: unix | Interface Layer: rre ------------------------------------------------------------------------ unix:pclose Data: n- Addr: - Float: - Close a pipe. Class: class:word | Namespace: unix | Interface Layer: rre ------------------------------------------------------------------------ unix:popen Data: sn-n Addr: - Float: - Open a pipe. Takes a command to run, and a file mode (`file:R` or `file:W`; `file:R+` may work on some systems). Returns a file ID usable with words in the `file:` namespace. Class: class:word | Namespace: unix | Interface Layer: rre ------------------------------------------------------------------------ unix:putenv Data: s- Addr: - Float: - Takes a string in the form `name=value` and sets an environment variable named `name` to `value`. Class: class:word | Namespace: unix | Interface Layer: rre Example #1: 'EDITOR=vi unix:putenv ------------------------------------------------------------------------ unix:sleep Data: n- Addr: - Float: - Sleep for the specified number of seconds. Class: class:word | Namespace: unix | Interface Layer: rre ------------------------------------------------------------------------ unix:system Data: s- Addr: - Float: - Runs another application using the system shell and returns after execution is completed. Class: class:word | Namespace: unix | Interface Layer: rre Example #1: 'ls_-lh_/etc unix:system ------------------------------------------------------------------------ unix:time Data: -n Addr: - Float: - Return a timestamp. Class: class:word | Namespace: unix | Interface Layer: rre ------------------------------------------------------------------------ unix:wait Data: -n Addr: - Float: - Waits for a child process to complete. This maps to the wait() system call. Class: class:word | Namespace: unix | Interface Layer: rre ------------------------------------------------------------------------ unix:write Data: sh- Addr: - Float: - Write a string to the specified file handle. Class: class:word | Namespace: unix | Interface Layer: rre ------------------------------------------------------------------------ until Data: q- Addr: - Float: - Execute quote repeatedly while the quote returns a value of `FALSE`. The quote should return a flag of either `TRUE` or `FALSE`, though `until` will treat any non-zero value as `TRUE`. Class: class:word | Namespace: global | Interface Layer: all Example #1: #10 [ dup n:put nl n:dec dup n:zero? ] until ------------------------------------------------------------------------ v:dec Data: a- Addr: - Float: - Decrement the value stored at the specified address by 1. Class: class:word | Namespace: v | Interface Layer: all ------------------------------------------------------------------------ v:dec-by Data: na- Addr: - Float: - Decrement the value stored at the specified address by the specified value. Class: class:word | Namespace: v | Interface Layer: all ------------------------------------------------------------------------ v:inc Data: a- Addr: - Float: - Increment the value stored at the specified address by 1. Class: class:word | Namespace: v | Interface Layer: all ------------------------------------------------------------------------ v:inc-by Data: na- Addr: - Float: - Increment the value stored at the specified address by the specified value. Class: class:word | Namespace: v | Interface Layer: all ------------------------------------------------------------------------ v:limit Data: alu- Addr: - Float: - Fetch the value stored at the address, then run `n:limit` against it, using the specified lower and upper bounds. Then store the resulting value back to the original address. Class: class:word | Namespace: v | Interface Layer: all ------------------------------------------------------------------------ v:off Data: a- Addr: - Float: - Set a variable to 0. Class: class:word | Namespace: v | Interface Layer: all ------------------------------------------------------------------------ v:on Data: a- Addr: - Float: - Set a variable to -1. Class: class:word | Namespace: v | Interface Layer: all ------------------------------------------------------------------------ v:preserve Data: aq- Addr: - Float: - Make a copy of the value at the address, then run the quote. Once the quote completes, restore the address to the specified value. Class: class:word | Namespace: v | Interface Layer: all ------------------------------------------------------------------------ v:update-using Data: aq- Addr: - Float: - Fetch a value from the specified address, then run the quotation with this value on the stack. Afterwards, store the returned value at the original address. Class: class:word | Namespace: v | Interface Layer: all ------------------------------------------------------------------------ var Data: s- Addr: - Float: - Create a variable. The variable is initialized to 0. Class: class:word | Namespace: global | Interface Layer: all Example #1: 'Base var ------------------------------------------------------------------------ var Data: ns- Addr: - Float: - Create a variable with the specified initial value. Class: class:word | Namespace: global | Interface Layer: all Example #1: #10 'Base var ------------------------------------------------------------------------ while Data: q- Addr: - Float: - Execute quote repeatedly while the quote returns a `TRUE` value. The quote should return a flag of either `TRUE` or `FALSE`, though `while` will treat any non-zero value as `TRUE`. Class: class:word | Namespace: global | Interface Layer: all Example #1: #10 [ dup n:put nl n:dec dup n:-zero? ] while ------------------------------------------------------------------------ xor Data: mn-o Addr: - Float: - Perform a bitwise XOR operation. Class: class:primitive | Namespace: global | Interface Layer: all ------------------------------------------------------------------------ { Data: - Addr: - Float: - Begin an array. This is intended to make creating arrays a bit cleaner than using a quotation and `a:counted-results`. Class: class:word | Namespace: global | Interface Layer: all ------------------------------------------------------------------------ {{ Data: - Addr: - Float: - Begin a lexically scoped area. Class: class:word | Namespace: global | Interface Layer: all ------------------------------------------------------------------------ } Data: -a Addr: - Float: - Complete an array begun by `{`. Returns a pointer to the data. Class: class:word | Namespace: global | Interface Layer: all ------------------------------------------------------------------------ }as Data: f- Addr: - Float: - End an assembly section. Class: class:macro | Namespace: global | Interface Layer: all ------------------------------------------------------------------------ }} Data: - Addr: - Float: - End a lexically scoped area. This will hide any headers between `{{` and `---reveal---`, leaving only headers between `---reveal---` and the `}}` visible.
