生成后的模板标识

Question

I'm generating a makefile using GO text/template The template is generated as expected (with the right content ) but the problem is that it’s not indented with tabs and I got errors while running make command after generation.

This is the output of the template:

all: app app_2

DIR = $(PWD)
.PHONY: app
app:
@echo "run module 1"

.PHONY: app_2
app_2:
@echo "run module 2”

When I run make I got error "makefile:7: *** missing separator. Stop.” (This is the line with the first echo”)

If I change the ideation to tab (after the file was generated) with Goland or vsCode, I was able to run the file successfully and see the expected output..., any idea how to make it work with go text/template ?

This is the template

all: {{- range .Load.Proc}} {{.Name}}{{end}}


{{- range .Load.Proc}}
.PHONY: {{.Name}}
{{.Name}}:
    @echo {{.Text}}
{{end}}

This is the makefile issue: makefile:4: *** missing separator. Stop but for me it's a problem since I want to generate the file without the need to manually change the indentation.

Use tab characters in the template to produce tabs in the output. To fix the template in the question, replace the spaces before @echo with a tab character.

If you cannot put tabs in the template for some reason, then use {{"\t"}} to produce a tab in the output:

{{"\t"}}echo {{.Text}}
