我正在尝试基于使用“;”的CSV文件的内容创建组织表。作为分隔符。
我认为使用源代码块来“捕获”文件的内容,然后将结果传递给创建表的函数会很容易,但是我陷入了困境:我找不到一种方法使用第一个源代码块的“结果”。我知道的功能(org-table-convert-region)期望可以使用一个区域,但我不知道如何将“ cat”编辑的文本作为区域传递。
#+NAME: csvraw
#+BEGIN_SRC sh :results raw
cat afile.csv
#+END_SRC
非常感谢您的帮助,以生成一个代码块,该代码块从我的csv文件中生成一个组织表,该文件包含以下行:
ID;Region;SubRegion;Area;No
1234;Asia;India;45;2
24251;Europe;Romania;456;67

有org-table-convert-region
(绑定到C-c |
)可以很简单地进行转换。唯一的技巧是将;
指定为分隔符。您可以通过使用适当的前缀参数来调用它-文档字符串说:
(org-table-convert-region BEG0 END0 &optional SEPARATOR)
Convert region to a table.
The region goes from BEG0 to END0, but these borders will be moved
slightly, to make sure a beginning of line in the first line is included.
SEPARATOR specifies the field separator in the lines. It can have the
following values:
(4) Use the comma as a field separator
(16) Use a TAB as field separator
(64) Prompt for a regular expression as field separator
integer When a number, use that many spaces, or a TAB, as field separator
regexp When a regular expression, use it to match the separator
nil When nil, the command tries to be smart and figure out the
separator in the following way:
- when each line contains a TAB, assume TAB-separated material
- when each line contains a comma, assume CSV material
- else, assume one or more SPACE characters as separator.
(64)
值仅连续三个C-u
,因此过程如下:
C-x i
插入CSV文件。C-x C-x
将插入的内容标记为活动区域。C-u C-u C-u C-c | ; RET
更酷的是,在CSV文件的第一行和其余各行之间保留一个空行,将使第一行自动成为表格的标题。
您也可以将其包装在代码块中:
#+begin_src elisp :var file="/tmp/foo.csv" :results raw
(defun csv-to-table (file)
(with-temp-buffer
(erase-buffer)
(insert-file file)
(org-table-convert-region (point-min) (point-max) ";")
(buffer-string)))
(csv-to-table file)
#+end_src
#+RESULTS:
| a | b | c |
|---+---+---|
| d | e | f |
| g | h | i |

(defun jea-convert-csv-to-org-table (fname)
(interactive "fCSV to convert: ")
(let ((result '("|-\n")))
(with-temp-buffer
(save-excursion (insert-file-contents-literally fname))
(while (and (not (eobp)) (re-search-forward "^\\(.+\\)$" nil t nil))
(push (concat "|" (replace-regexp-in-string ";" "|" (match-string 1)) "|\n")
result))
(push '"|-\n" result))
(concat (seq-mapcat #'identity (reverse result)))))
将elisp代码安装在〜/ .emacs文件中,然后重新启动emacs。或者更好的是,eval
使其存在( CTRL + x,CTRL + e 或 ALT + x eval-last-sexp )。
#+NAME: csvraw
#+BEGIN_SRC elisp :results raw
(jea-convert-csv-to-org-table "/Users/jamesanderson/Downloads/test1.csv")
#+END_SRC
请注意,上述内容已从elisp
更改为sh
。这是它的实际效果:
emacs converting csv to org table
该代码并未针对大型文件进行优化,并且坦率地说,很快就将它们组合在一起。但是,经过少量测试,似乎可以正常工作。
