Move error codes
Works towards #66210.
r? @Centril
Oh btw, for the ones interested, I used this python script to get all error codes content sorted into one final file:
<details>
```python
from os import listdir
from os.path import isdir, isfile, join
def get_error_codes(error_codes, f_path):
with open(f_path) as f:
short_mode = False
lines = f.read().split("\n")
i = 0
while i < len(lines):
line = lines[i]
if not short_mode and line.startswith("E0") and line.endswith(": r##\""):
error = line
error += "\n"
i += 1
while i < len(lines):
line = lines[i]
error += line
if line.endswith("\"##,"):
break
error += "\n"
i += 1
error_codes["long"].append(error)
elif line == ';':
short_mode = True
elif short_mode is True and len(line) > 0 and line != "}":
error_codes["short"].append(line)
while i + 1 < len(lines):
line = lines[i + 1].strip()
if not line.startswith("//"):
break
parts = line.split("//")
if len(parts) < 2:
break
if parts[1].strip().startswith("E0"):
break
error_codes["short"][-1] += "\n"
error_codes["short"][-1] += lines[i + 1]
i += 1
i += 1
def loop_dirs(error_codes, cur_dir):
for entry in listdir(cur_dir):
f = join(cur_dir, entry)
if isfile(f) and entry == "error_codes.rs":
get_error_codes(error_codes, f)
elif isdir(f) and not entry.startswith("librustc_error_codes"):
loop_dirs(error_codes, f)
def get_error_code(err):
x = err.split(",")
if len(x) < 2:
return err
x = x[0]
if x.strip().startswith("//"):
x = x.split("//")[1].strip()
return x.strip()
def write_into_file(error_codes, f_path):
with open(f_path, "w") as f:
f.write("// Error messages for EXXXX errors. Each message should start and end with a\n")
f.write("// new line, and be wrapped to 80 characters. In vim you can `:set tw=80` and\n")
f.write("// use `gq` to wrap paragraphs. Use `:set tw=0` to disable.\n\n")
f.write("syntax::register_diagnostics! {\n\n")
error_codes["long"].sort()
for i in error_codes["long"]:
f.write(i)
f.write("\n\n")
f.write(";\n")
error_codes["short"] = sorted(error_codes["short"], key=lambda err: get_error_code(err))
for i in error_codes["short"]:
f.write(i)
f.write("\n")
f.write("}\n")
error_codes = {
"long": [],
"short": []
}
loop_dirs(error_codes, "src")
write_into_file(error_codes, "src/librustc_error_codes/src/error_codes.rs")
```
</details>
And to move the error codes into their own files:
<details>
```python
import os
try:
os.mkdir("src/librustc_error_codes/error_codes")
except OSError:
print("Seems like folder already exist, moving on!")
data = ''
with open("src/librustc_error_codes/error_codes.rs") as f:
x = f.read().split('\n')
i = 0
short_part = False
while i < len(x):
line = x[i]
if short_part is False and line.startswith('E0') and line.endswith(': r##"'):
err_code = line.split(':')[0]
i += 1
content = ''
while i < len(x):
if x[i] == '"##,':
break
content += x[i]
content += '\n'
i += 1
f_path = "src/librustc_error_codes/error_codes/{}.md".format(err_code)
with open(f_path, "w") as ff:
ff.write(content)
data += '{}: include_str!("./error_codes/{}.md"),'.format(err_code, err_code)
elif short_part is False and line == ';':
short_part is True
data += ';\n'
else:
data += line
data += '\n'
i += 1
with open("src/librustc_error_codes/error_codes.rs", "w") as f:
f.write(data)
```
