 # runfile (`rfile`)

+a **suckless** and **minimal**, **POSIX C99** alternative to `Makefile`/`justfile`!
+

+
+## `rfile` syntax & features
+
+- `#` -> ignore line (comment)
+
+
+### variables
+
+the variable system in `rfile`s is very minimal:
+
+- every variable is a _string_
+- when accessed, `rf` text-substitutes the variable with its content
+
+example:
+```
+@cc=gcc
+@inp=rf.c
+@out=rf
+@opts=-Wall -Wextra -pedantic -std=c99
+
+@cc @inp -o @out @opts
+# becomes 'gcc rf.c -o rf -Wall -Wextra -pedantic -std=c99'
+```
+
+
+### rfile command prefix (`@`) 
+
+- `@: [msg]` -> print/log
+- `@var=cmd` -> create variable `var`
+- `@var` -> access variable `var`
+
+
+### command sections
+
+example syntax:
+
+```
+section {
+    @: hello!
+}
+```
+
+every other line is treated as a command and will run normally.
+
+> if no section is specified when calling `rf`, only commands in global scope will run.
+
+---
 
 ## usage
-1. create an `rfile` with commands divided by a `\n`
-2. run `rf` in that directory.
+
+1. create an `rfile`.
+2. run `rf [section name]` :)
