The Fish shell parser written in Go.
This is a library to parse Fish shell script. Use like
tree := parser.ParseExpr("ls -la | cat -\n")and get AST node tree.
It can be printed like this:
ast.Print(tree) 0 ast.Stmts (len = 1) {
1 . 0: ast.PipeStmt {
2 . . Lhs: ast.CmdStmt {
3 . . . Cmd: ast.StrExpr (len = 1) {
4 . . . . 0: ast.Ident {
5 . . . . . Name: "ls"
6 . . . . }
7 . . . }
8 . . . Args: []ast.Expr (len = 1) {
9 . . . . 0: ast.StrExpr (len = 1) {
10 . . . . . 0: ast.Ident {
11 . . . . . . Name: "-la"
12 . . . . . }
13 . . . . }
14 . . . }
15 . . }
16 . . Rhs: ast.CmdStmt {
17 . . . Cmd: ast.StrExpr (len = 1) {
18 . . . . 0: ast.Ident {
19 . . . . . Name: "cat"
20 . . . . }
21 . . . }
22 . . . Args: []ast.Expr (len = 1) {
23 . . . . 0: ast.StrExpr (len = 1) {
24 . . . . . 0: ast.Ident {
25 . . . . . . Name: "-"
26 . . . . . }
27 . . . . }
28 . . . }
29 . . }
30 . }
31 }
Experimental. The API can be changed roughly!
