:s/from/to/g only replaces one occurence in markdown-mode

[norcalli]

Description

:s/from/to/g doesn't replace all occurences on the line, but the preview shows the correct replacement.

Reproduction guide

• Start Emacs
• Open a README.md
• Type :.s/./x/g

Observed behaviour:
Only the first occurence is replaced, but the preview shows all occurences being replaced.

Expected behaviour:
All occurrences should be replace with the g flag.

Just to be sure, dotspacemacs-ex-substitute-global is set to nil in your .spacemacs?

[norcalli]

Yup, not present at all in my .spacemacs.

[sooheon]

Also check the value of evil-ex-substitute-global directly with C-h v rather than look in your .spacemacs, see what emacs has the value as.

[norcalli]

Ah gotcha. It is definitely nil.

[sooheon]

If it's still consistent, some better steps to reproduce starting from emacs -Q and initializing the minimum packages will be helpful.

markdown-mode had issue which overwrites match-data. I fixed it at jrblevin/markdown-mode#105. Could you try with latest version ?

[norcalli]

@syohex Hooray! I can confirm that this is fixed. Thanks for the quick turnaround time!
