[feature] rename all symbols between camelCase and snake_case about ast-grep

[HerringtonDarkholme]

Sorry I didn't get your point.

If you need a rule to convert identifier, https://ast-grep.github.io/reference/yaml/transformation.html#convert can do that already.

convert can do that already

aah! also Use transform in Rewrite. but the docs have no full example

i just cant get this working... this should rename some_var to someVar
ast-grep always shows the interactive screen, but it should just patch input.py

cat >input.py <<'EOF'
some_var = 1
print(some_var)
EOF

cat >rules.yaml <<'EOF'
id: fix-case
language: python
rule:
  pattern: $X
  kind: identifier
transform:
  X2:
    convert:
      toCase: camelCase
      source: $X
# edit: fix was missing
fix: $X2
EOF

ast-grep scan -U -r rules.yaml input.py

You also need a fix field to apply the fix. https://ast-grep.github.io/reference/yaml/fix.html

id: fix-case
language: python
rule:
  pattern: $X
  kind: identifier
transform:
  X2:
    convert:
      toCase: camelCase
      source: $X
fix: $X2

Please read the doc. https://ast-grep.github.io/guide/rewrite-code.html
